Background technology
Building energy conservation is main contents of carrying out national environmental protection and save energy policy, is the important component part of implementing national economy sustainable development.Nation-building portion has issued files such as " the energy-conservation detailed rules for the implementation of urban architecture " in nineteen ninety-five, " covil construction energy-saving design standard<heating residential architecture part〉" JGJ26-95 is classified as compulsory standard, the Ministry of Construction has issued the 76th command " covil construction administration of energy conservation regulation " again on October 1st, 2000 simultaneously, to not meeting the project of energy conservation standard, must not approve the construction of.Under the guidance of a series of like this energy saving policy, rules, standard and compulsive clause, the energy conservation of China's dwelling construction deepens continuously, energy conservation standard improves constantly, and introduces and has developed many novel power-saving technologies and material, vigorously promotes the use in residential housing.
But the building energy conservation level that China is present, also far below developed country, China's construction unit area energy consumption is still 3-5 times of the close developed country of weather.The building heating energy consumption of north cold area has accounted for more than 20% of local whole society energy consumption, and the overwhelming majority all is to adopt thermal power generation and coal firing boiler, brings serious pollution to environment simultaneously.Therefore the novel building building enclosure just tightly links together with energy-conservation, and building is carried out the energy-conservation instant task that become.Building energy conservation is reflected on the building enclosure, exactly building enclosure is incubated, thereby reaches purpose of energy saving.
Commonly used enclosed structure is incubated is exterior-wall heat insulation, refer to adopt certain fixed form (bonding, mechanical anchor, stickup+mechanical anchor, spraying, cast etc.), the thermal insulation material and the building masonry wall of thermal conductivity lower (heat insulating effect is better) are fixed as one, increase the evenly heat resistance of body of wall, thereby reach a kind of engineering way of insulation or effect of heat insulation.
EPS exterior-wall heat insulation and facing system are the most effective heat preservation energy-saving modes in the current all kinds of building.And along with deeply carrying out of China's building energy conservation policy, the EPS External Thermal Insulation Technology for External will be widelyd popularize and be popularized.Because the EPS plate is soft, Gu and external insulation system outside not the exemplary application unit surface heavily manage bigger ceramic tile etc. than heavy material, generally select for use coating as exterior finishing material, because of mostly currently marketed coating products is to design at common body of wall, there is not heat insulation effect, and the requirement to the EPS external wall heat insulation system does not well suit, so coating ornamental surface layer cracking usually appears in current external insulation system, influences final decorative effect.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of special paint for external thermal insulation system of outer wall, by the interpolation of optimization of formulation and functional material, improved material in the anti-down anti-sticking effect of high-temperature condition; Increased the thermal resistance of coating products, made that the function of whole heat insulation system is promoted; Improved the resistance to cleavage of coating products.
The present invention realizes by following technical scheme:
