Problems solved by technology

However, if the prefabricated house is applied to outdoor camping, the foamed cement composite board is heavy and inconvenient to carry, which limits the application of the prefabricated house outdoors.
If the insulation board is used to assemble the outdoor house, its structural strength cannot meet the requirements

Abstract

The invention relates to an inert closed-pore perlite fire-insulation heat-insulation wallboard, the inert closed-pore perlite fire-insulation heat-insulation wallboard comprises a heat insulating block and a reinforcing layer disposed on the outer surface of the heat insulating block, wherein the heat insulating block is prepared by mixing raw materials of 50-70 parts by weight of closed-cell perlite, 15 to 25 parts by weight of silicate, 5 to 10 parts by weight of fiber, 5 to 15 parts by weight of fly ash, 3 to 8 parts by weight of volcanic ash, 15 to 20 parts by weight of a polyurea prepolymer, 5 to 6 parts by weight of polyurethane gel, 4 to 6 parts by weight of a flame retardant, 1 to 1.5 parts by weight of a diamine chain extender, 3 to 5 parts by weight of graphene and 5 to 8 partsby weight of a solvent, and the reinforcing layer is prepared by spraying after mixing raw materials of 3 to 4 parts by weight of the polyurea prepolymer, 1 to 1.3 parts by weight of the polyurethanegel, 1.6 to 2 parts by weight of the flame retardant, 0.3 to 0.5 part of the diamine chain extender, 1 to 1. 3 parts by weight of the graphene and 2.5 to 3.5 parts by weight of the solvent; wherein the shell of the closed-pore perlite is filled with an inert gas. The inert closed-pore perlite fire-insulation heat-insulation wallboard not only has the characteristics of light weight and heat preservation, but also has high structural strength and excellent flame retardant and antiknock performance.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, more specifically, it relates to an inert closed-cell perlite fireproof and heat-insulating wallboard. Background technique [0002] Prefabricated buildings refer to buildings assembled on site with prefabricated components. The prefabricated concrete components of this type of building are mainly composed of post-cast concrete, grout anchors or superimposed methods at the connection parts. The assembled integral concrete structure has reliability. The force transmission structure and meet the bearing requirements. In urban construction, there are more and more prefabricated buildings. Assembled structural components are industrially produced, and the quality of components is easy to guarantee. The on-site construction is simple and fast, and there is less construction waste, which greatly improves the efficiency of housing construction. In the process of urbanization, prefabricat...
