Abstract

The invention provides a composite vacuum insulation board for a building exterior wall and a preparation method thereof. The composite vacuum insulation board for the building exterior wall comprisesa surface layer, a vacuum insulation board and a substrate layer which are sequentially arranged, wherein the vacuum insulation board is separately connected with the surface layer and the substratelayer through rigid foam polyurethane. According to the composite vacuum insulation board, the rigid foam polyurethane is used for connecting the surface layer, the vacuum insulation plate and the substrate layer, so that the rigid foam polyurethane can not only play a role in bonding, but also play a role in protecting the vacuum insulation plate, and the problem that the insulation effect is reduced due to the fact that the vacuum insulation plate is not prone to bond with the wall and is easy to destroy in the construction process is very well solved; and the surface layer, the vacuum insulation plate and the substrate layer of the composite vacuum insulation plate for the building exterior wall form an organic whole, so that functions such as decoration and insulation can be completedthrough one process, the construction is convenient and fast, and the construction period is saved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a vacuum insulation board, in particular to a composite vacuum insulation board for building exterior walls and a preparation method thereof. Background technique [0002] With the development of the economy and the progress of the society, the rapid development of the construction industry and the rapid improvement of the living environment, the requirements for building materials are getting higher and higher. In order to improve the energy-saving effect, vacuum insulation panels have gradually attracted people's attention. The vacuum insulation panel is composed of the filling core material and the vacuum protection surface layer, which can effectively avoid the heat transfer caused by air convection, so the thermal conductivity can be greatly reduced, which is 1 / 10 of the thermal conductivity of traditional thermal insulation materials. However, there are still some ...
