Heat insulation board

Abstract

The invention relates to a heat insulation board, in particular to a board which can perform heat insulation through an alkali-resisting gridding cloth layer. The heat insulation board comprises a panel. The panel comprises a bottom layer, a intermediate layer and a surface layer. The bottom layer, the intermediate layer and the surface layer are composited together. The intermediate layer is sequentially provided with a treatment layer, a waterproof coating, a connecting layer, the alkali-resisting gridding cloth layer and a protective layer from bottom to top. The design of the alkali-resisting gridding cloth layer is adopted, a glass fiber gridding cloth inner wall heat insulation alkali-resisting glass fiber net is formed by taking a medium-alkali or alkali-free glass fiber gridding cloth as a base material and then coating the medium-alkali or alkali-free glass fiber gridding cloth with modified acrylic ester copolymerization glue solution and has the advantages of being light in mass, high in strength, resistant to temperature and alkali, waterproof and resistant to corrosion and fracturing and the like, and cracking caused by overall plaster layer surface tension retraction and external force can be effectively avoided. The light and thin gridding cloth is often used for wall renovation and inner wall insulation; and by using the alkali-resisting gridding cloth layer, not only can the wall heat insulation effect be improved, but also the service life of the heat insulation board can be prolonged.

Description

technical field [0001] The invention relates to a thermal insulation board, in particular to a board which can be insulated through an alkali-resistant grid cloth layer. Background technique [0002] In our daily life, maintaining a constant indoor temperature will make us feel more comfortable. For example, heating in winter and cooling in summer can only occur by consuming fossil resources. According to statistics, during the air-conditioning season, the consumption of air-conditioning is 44% to 51% of the power consumption, so the indoor thermal insulation plays a decisive role. [0003] The existing indoor thermal insulation materials mostly use benzene board, but its disadvantages are aging resistance, large deformation coefficient, poor stability, poor safety, easy to burn, poor ecological environmental protection, difficult construction, high engineering cost, limited resources and difficult recycling use. From the perspective of environmental protection, cork has g...

[0003] The existing indoor thermal insulation materials mostly use benzene board, but its disadvantages are aging resistance, large deformation coefficient, poor stability, poor safety, easy to burn, poor ecological environmental protection, difficult construction, high engineering cost, limited resources and difficult recycling use

From the perspective of environmental protection, cork has a good insulation effect, but the cost is too high; and if the insulation board is used in a humid environment, the insulation board will rot easily and the safety is poor
