Embodiment Construction
[0026] see figure 1 , A new type of inorganic polyurethane thermal insulation veneer decoration system, the system includes a bottom adhesive layer 2, a thermal insulation and fireproof board 3, a surface layer adhesive layer 4, and a protective finishing layer 5 from the outer wall base surface 1 to the outside.
[0027] The bonding layer 2 is composed of strip-shaped polymer bonding mortar located in the surrounding frame of the thermal insulation and fireproof layer 3 and a dot-shaped polymer bonding mortar in the middle, with a thickness of 5-10 mm.
[0028] The polymer bonding mortar is a general bonding mortar in construction.
[0029] The thermal insulation and fireproof board 3 is a rigid foam polyurethane PUR or PIR board with a thickness of 20-200mm.
[0030] The surface layer adhesive layer 4 is configured by modified polyurethane adhesive or polymer emulsion and heavy calcium carbonate, and has a thickness of 0.5-1.5 mm.
[0031] The protective finishing layer 5 ...
