Abstract

The invention discloses a novel fiber reinforced composite heat insulation plate and a preparing method of the novel fiber reinforced composite heat insulation plate, wherein the novel fiber reinforced composite heat insulation plate comprises a decoration surface layer, a bottom layer and a heat insulation core layer; the heat insulation core layer is clamped between the decoration surface layer and the bottom layer; the decoration surface layer and the bottom layer are made of polymer modified mortar; the heat insulation core layer is manufactured by injecting inorganic foaming materials into three-dimensional fiber fabrics; the decoration surface layer is connected with the upper part of the heat insulation core layer; and the bottom layer is connected with the lower part of the heat insulation core layer. The composite heat insulation plate has the advantages that the heat isolation and heat preservation effects are good; the weight is light; the intensity is high; and the durability is high. The composite heat insulation plate can be used as a heat insulation roof plate or a heat insulation external wall plate and the like for a mainstream building.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a novel fiber-reinforced composite thermal insulation board and a preparation method thereof. Background technique [0002] The most common traditional composite insulation board is "color steel polystyrene sandwich panel", which is a sandwich panel made of metal plate as the surface layer and polystyrene board as the core material. The same type of composite insulation board also has "color steel rock wool sandwich board", "color steel polyurethane sandwich board" and so on. These traditional insulation sandwich panels have some shortcomings: 1) low mechanical strength, especially low impact resistance; 2) poor corrosion resistance, especially in hot and humid environments; 3) the outer surface is monotonous Steel plates have poor touch and perception; 4) because the used insulation core material is a flammable material, there is a fire hazard.
