Background technique

At present, there are nearly 60 billion square meters of existing buildings in China, 97% of which are non-energy-saving buildings. It is a trend of national economic development to vigorously develop building insulation and energy conservation. Energy-saving renovation of existing buildings is also a direction of building development. The current thermal insulation and decoration integrated product market includes three categories: 1. Coating decoration system with calcium silicate board and cement fiber board as the panel; 2. Thermal insulation and decoration system with thin stone and ceramics as decoration materials; Metal plate thermal insulation and decoration integrated system formed by metal plate wrapping.

As we all know, organic thermal insulation core materials have the advantages of low thermal conductivity and good thermal insulation effect, but have disadvantages such as flammability and smoke generation; inorganic thermal insulation core materials have the advantages of flame retardant and no smoke, but are easy to pulverize, crack, and absorb water to expand Lead to late cracking, falling off and other problems occur from time to time. In addition, the disadvantages of calcium silicate board or cement fiber board are high density, high weight, high water absorption rate, and easy warping. Large potential safety hazards; thin stone and ceramics are heavy, and dry-hanging construction is required, which not only wastes resources, but also costs costs; metal plates have disadvantages such as deformation and heat transfer.

Chinese invention patent CN 103276867A discloses a color-finish thermal insulation and decoration integrated board. The thermal insulation board is cut into standard-sized boards, and then a high-pressure air pump is used to spray or smear colored decorative mortar on the surface of the thermal insulation board. Under the conditions of 10-30°C and humidity of 50-80%, curing for 5-7 days, the integrated board of color mortar facing, thermal insulation and decoration can be obtained. This patent adopts the direct spraying and smearing of facing mortar, which is not shot blasting or sandblasting, and it is difficult to achieve the surface effect of natural stone.

Chinese invention patent CN107386561A discloses a light-weight fire-proof heat-preservation decorative composite board and its preparation method. The first layer is a thermal insulation board with fire protection requirements above Class A. The two sides of the thermal insulation board are leveling layers. One end of the piece can be inserted into the installation channel of the anchor piece to fix the lightweight fireproof and thermal insulation composite board on the installation body. The patent relates to decorative lightweight flexible sheets, installation channels, and thermal insulation boards with Class A flame retardant requirements, but has never been involved in organic thermal insulation boards. In addition, this patent has nothing to do with the safety of the slot.
