Light fireproof heat-insulation decorative composite plate and method for preparing same

Abstract

The invention provides a light fireproof heat-insulation decorative composite plate and a method for preparing the same. The light fireproof heat-insulation decorative composite plate comprises a surface layer and a heat-insulation layer. The surface layer is a light flexible sheet with decorative finish, the heat-insulation layer is a heat-insulation plate which meets at least A-level fireproof requirements, leveling layers are arranged on two surfaces of the heat-insulation plate, the light flexible sheet with the decorative finish is arranged on the leveling layer on one of the surfaces of the heat-insulation plate by means of composition, anchoring component mounting straight slots are further formed in the heat-insulation plate, one end of each anchoring component can be inserted in the corresponding anchoring component mounting straight slot, and the light fireproof heat-insulation decorative composite plate can be fixed onto a mounting body. The light fireproof heat-insulation decorative composite plate and the method have the advantages that the surface layer is the light flexible sheet, accordingly, the weight of the light fireproof heat-insulation decorative composite plate can be reduced to a great extent, and the safety can be greatly improved; the light fireproof heat-insulation decorative composite plate is provided with the anchoring component mounting straight slots, and accordingly high and reliable anchoring force can be exerted; the heat-insulation layer is the heat-insulation plate which meets the at least A-level fireproof requirements, accordingly, the light fireproof heat-insulation decorative composite plate has an excellent fireproof function, has the light weight per unit area and can be firmly mounted, and the shortcomings in the prior art can be overcome.

Description

technical field [0001] The invention relates to thermal insulation and decoration materials for buildings, and belongs to the technical field of energy-saving thermal insulation and decoration of building exterior walls. More specifically, it relates to a lightweight fireproof thermal insulation decorative composite board and a preparation method thereof. Background technique [0002] At present, the fire-proof, thermal insulation and decorative composite panels above grade A on the market are mainly composed of inorganic panels or metal panels with a decorative layer, mostly using inorganic panels, such as calcium silicate boards, high-pressure cement fiber boards, etc. as decorative surface carriers, and A It is compounded with thermal insulation materials above grade (such as rock wool tape composite board), which has the advantage of good decorative surface effect, but the weight of inorganic calcium silicate board and high-pressure cement fiber board is relatively heavy....

AI Technical Summary

Problems solved by technology

[0002] At present, the fire-proof, thermal insulation and decorative composite panels above grade A in the market are mainly composed of inorganic panels or metal panels with decorative layers, and inorganic panels, such as calcium silicate boards, high-pressure cement fiber boards, etc. are used as decorative surface carriers. It is made of thermal insulation materials above grade (such as rock wool tape combined board), which has the advantage of good decorative surface effect, but the weight of inorganic calcium silicate board and high-pressure cement fiber board is relatively heavy. In addition, as we all know, the main It is an inorganic thermal insulation material, and the density of inorganic thermal insulation materials is relatively high, and its mass per unit area is relatively large. Requirements, usually the thickness of thermal insulation materials above grade A is relatively thick, coupled with the weight of panels and / or bottom panels, its mass per unit area often exceeds the upper limit of 30kg / ㎡ stipulated in the industry standard JG / T287-2013, and thermal insulation decoration The greater the weight of the composite board, the lower the safety factor, and the higher the requirements for the bonding and anchoring strength of the base wall

In addition, at the project site, this type of thermal insulation and decorative composite board needs to be cut by a dedicated large-scale machine. The number of machines and the ability of the operator will affect the quality and efficiency of the cutting board.
