Vigorously promoting external insulation technology, new energy-saving materials to strengthen the development and use of energy-saving construction so that really to be implemented.Key words: energy-saving building；materials The implementation of building energy conservation and environmental protection and energy conservation policy and the main contents of the national economy and implementing sustainable development is an important component part. In such a series of energy conservation policies, regulations, standards and mandatory provisions under the guidance of China's energy-saving housing construction work has been constantly deepened, energy conservation standards continuously, and the introduction of development, many new energy-saving technologies and materials, and in residential buildings to promote use. However, China's current level of building energy conservation, but also much lower than the developed countries, China's energy consumption per unit area construction climate is similar to the developed countries, three times to five times. Cold in the north building heating energy consumption accounts for the local society more than 20% of energy consumption, and the vast majority are used in thermal power generation and coal-fired boilers, at the same time to cause serious environmental pollution. Therefore, the construction of this century, China's energy-saving construction is an important topic. In the construction of the external structure for the heat loss larger, external retaining structure in the wall and make up a large share. Therefore, the reform and building wall wall is the development of energy-saving technologies building energy-saving technology one of the most important part of the external wall insulation technology and the development of energy-saving construction materials is the main energy-saving mode.1.An external wall insulation technology Energy-saving insulation wall construction techniques can be divided into external walls, insulation and Exterior Insulation two categories.1.1 insulation technology and its features External wall insulation in construction, in the internal and external structure to the insulation layer. Construction of insulation fast, convenient operation flexible and can ensure the construction progress. Application of thermal insulation within a longer time, mature technology, construction techniques and testing standards are relatively sound. In 2001 the external wall insulation in construction, about 90 percent of the engineering applications, insulation technology. Been in the area to promote the insulation technology: Enhanced gypsum composite polystyrene insulation board, polymer mortar composite polystyrene insulation board, reinforced cement composite polystyrene insulation board, the Interior paste polystyrene board clean wall plaster and polystyrene particles floor insulation Mortar and cracking slurry pressure Network Haile practice. However, the use of thermal insulation will be more occupied area, "thermal bridge" is no easy solution, making it easy to crack, but will also affect the construction speed, the second decoration of the affected residents, and the hoisting of the interior walls and fixed objects can easily damage the insulation structure. Insulation within the technical unreasonable, its decision must be replaced by the insulation. 3 string 1.2, and its technical characteristics of insulation Exterior Insulation is vigorously promoting the construction of a thermal insulation energy-saving technologies. Exterior Insulation compared with the thermal insulation, technical reasonable, and there are obvious advantages of using the same specifications, the same size and performance of insulation materials, exterior insulation, insulation effect than good. Exterior Insulation technology not only apply to the new structure works, but also to transform the old buildings, applicable to a wide range of high technology content; exterior insulation package in the main structure of the outer side to protect the main structure, and extend the life of buildings; effectively reduce The thermal structure of the bridge, construction of an effective increase in space at the same time eliminating condensation and improve the living comfort. Materials net Currently insulation on the external walls of relatively mature technologies include the following types. 1.2.1 plug-Exterior Insulation Plug the insulation material ROCK (ORE), cotton, glass wool carpets, polystyrene foam (polystyrene board, EPS, XPS), polyphenylene Artificial Stone ceramic decorative concrete composite insulation panels, steel mesh-Sandwich such as wallboard. One for polystyrene board has excellent physical properties and cheap cost, in the world has been within the scope of the external wall insulation plug technology is widely used. The technology is plug mortar or adhesive is used for the fixed pieces of insulation materials will be posted, pegged to the outer walls, then the floor cracking mortar, pressed glass fiber Mesh protective layer formation, and the last to do decorative surface. A further approach is the use of a dedicated fixed-absorbent will be difficult various insulation board fixed the outer walls, and then aluminium, natural stone, stained glass, and other pre-production plug in the keel, the direct formation of decorative surface. Mr. IM Pei designed by the Bank of China head office building, the insulation is used in this design. This plug-in insulation installation time-consuming, difficult construction and construction-led occupation period, the main question can only after acceptance construction. Conducting high-level construction, the construction of the security personnel not be guaranteed. 1.2.2 polystyrene board with a wall casting molding This technology is in the concrete frame - polystyrene board shear system will be built into the architecture template, will be pouring in the lateral wall, and then pouring concrete, concrete pouring and molding polystyrene board for a composite wall. The technology to solve the plug-in insulation of the main issues of its advantages is obvious. As the external walls of the main insulation layer with a survival, improve efficiency, greatly shorten the construction period, and the safety of construction workers be guaranteed. But in the winter construction, the role of polystyrene insulation Banqi can reduce the external envelope insulation measures. But we should pay attention to pouring concrete uniform, continuous casting, otherwise concrete lateral pressure caused the impact polystyrene board in the FORM REMOVAL after deformation and wrong stubble, impact on the construction sequence. The built-in polystyrene board which can be double-sided steel mesh, it could be a single screen of steel. Double Wire Fabric benzene plate and concrete connections, relies mainly on the medial wall and the steel mesh-banding and lateral reinforcement of concrete and polystyrene board of bonding, the combination of good performance, high security. Single Wire Fabric benzene plate and concrete connections, rely mainly on the concrete and polystyrene board and the bonding Chacha reinforced, L, such as steel and concrete wall of the anchorage, with better performance. And double steel mesh, compared to one-sided steel mesh technology with the cancellation of the inner steel mesh and installation of insulation board before the board lateral plastering, saving time and materials. Its cost can be reduced by 10 percent. However, the two approaches are used steel mesh planes, the higher cost, and the steel is hot-conductor, direct heat will be reduced wall insulation effect. We are concrete and polystyrene board with a grid molding compound wall were studied. The experimental results show that, in concrete slurry of suitable conditions, the direct use of concrete as an adhesive to paste polystyrene board, it is entirely possible. When we polystyrene board on the back of treatment, with concrete bonding further improve (the average bond strength can be achieved 0.07 Mpa, and damage occurred in polystyrene board). The technology-steel mesh canceled its performance of the insulation, and once again cut the cost of board. After its long-term durability demonstration, the project can be widely used.1.2.3 polystyrene insulation slurry particles external insulationWill be abandoned polystyrene plastic (for EPS) processing broken into the 0.5 to 4 mm particle, as a lightweight aggregate to the preparation insulation mortar. The technology includes the insulation layer, the protective layer and cracking impermeability of protection layer (or layer of impermeable surface cracking of the mortar in 1). ZL powder particles of polystyrene insulation materials and technology in 1998 by the Ministry of Construction as on the national law. This method is now widely recognized wall insulation technology. The construction technique is simple and can reduce the labor intensity, and improving work efficiency; difference in the quality of the structure from the impact of the wall on the defective construction of the wall need repair leveling, and the direct use of slurry Huabu insulation can avoid other Insulation Construction Technology for plastering leveling off Houer shedding phenomenon. At the same time the external wall insulation technology to solve the engineering harsh conditions resulting from the use of easy interface debonding hollowing, surface cracking, and other problems easier to achieve Exterior Insulation an important breakthrough technology. Insulation and other things, compared to the same insulating effect of the circumstances, its lower cost, lower housing construction costs. For example, with polystyrene insulation boards, compared to per square metre can reduce about 25 yuan. Fraunhofer-new home in Tianjin high-level external insulation is used in the works of such technology.Energy-saving insulation materials are adiabatic materials. Insulation material is used for building envelope or thermal equipment, heat transfer impedance of the material or composite materials, including insulation materials, including insulation materials. The significance of thermal insulation material, on the one hand to meet the architectural space or thermal equipment thermal environment, on the other hand in order to save energy. With worldwide energy growing tensions in the energy-saving aspects of thermal insulation material on the significance of significant outstanding. Residents generally only heating air conditioning, insulation enclosure through the use of material that can be on the basis of the existing energy-saving 50% to 80%. According to Japan's Energy Conservation Practice has proved that the use of 1 ton per insulation materials, can save three tons of standard coal / year, the energy efficiency of the cost of production is 10 times. Therefore, some countries insulation material as is the coal, petroleum, natural gas, nuclear energy after the fifth-largest "energy."Insulation on the external wall insulation is insulation materials as building envelope, development and application of highly efficient insulation thermal insulation material is to ensure that building an effective energy-saving measures. At present the world's least developed countries, are on the insulation material production and application very seriously, and energy-saving construction work is done well, and they attach importance to the development of insulation materials and are inseparable. 2.1 insulation material properties Adiabatic is to maximize the thermal impedance of the transmission and therefore asked the insulation material must be large and small thermal resistance of the thermal conductivity.Speaking from the composition of materials, organic polymer generally are smaller than the thermal conductivity inorganic materials; non-metallic thermal conductivity coefficient is less than metallic materials; gaseous substances is less than the thermal conductivity of liquid material, liquid than solid material. Therefore, in conditions permitting, should make full use of organic polymer materials or amorphous inorganic materials, which is beneficial for the insulation insulation.In addition, insulation insulation materials must also be able to resist the impact of load, the environment is consistent with the use of mechanical strength. Its better performance bond, still a small contraction rate and the environment in line with the durability. 9 string 3 Summary At present, China's external wall insulation technology developed very quickly, and energy conservation is the focus of the work. External wall insulation technology with the development of innovative energy-saving materials are inextricably linked, building energy efficiency must be the development of new energy-saving materials for the premise, there must be sufficient insulation insulation materials as a foundation. Energy-saving materials and the development of the external wall insulation must be technology, we can really play its role. It is precisely because of the energy-saving materials innovation, and the superiority of external insulation technology was increasing people's attention. Therefore, in the external wall insulation technology to promote the same time, we must step up the development of new energy-saving materials and the use and thus truly achieve energy-saving construction.
