Technical Field
The utility model relates to a building field especially relates to a waterproof polyurethane heat preservation outer wall for building.
Background
Building energy conservation is an important work for relieving the contradiction of energy shortage in China, improving the living and working conditions of people, reducing environmental pollution and promoting the sustainable development of economy. The building energy conservation mainly comprises three major parts, namely building roof heat preservation and insulation, building external maintenance wall bodies, external door and window heat preservation and insulation and building equipment energy conservation. At present, the energy-saving requirement of China on an external thermal insulation system of an external wall is that the energy is saved by 75 percent or more. The polyurethane has low heat conductivity coefficient and good thermal performance. When the density of the rigid polyurethane is 35-40 kg/m3, the thermal conductivity is only 0.018-0.024 w/(m.k), which is about half of that of EPS, and is the lowest thermal conductivity of all heat-insulating materials. Therefore, the polyurethane board is widely applied to the heat insulation of the outer wall, but the heat conductivity coefficient of the polyurethane board is improved along with the increase of the water content, so that the heat insulation performance of the polyurethane board is influenced, the hardness of the polyurethane board is lower, the connection with the wall body is weak, and the installation process is more complex.
