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 insulation boards (such as polyurethane insulation boards, phenolic insulation boards, etc.) are used to assemble outdoor houses, their structural strength cannot meet the requirements

Abstract

The invention relates to an inert glass bead explosion-proof heat-insulation paint. The inert glass bead explosion-proof heat-insulation paint comprises a component A and a component B at a weight ratio of 50-60:10-15; the component A comprises, by weight, 50 to 60 parts of a polyurea performed polymer, 5 to 10 parts of polyurethane gel, 8 to 15 parts of hollow glass bead, and 10 to 15 parts of afire retardant; and the component B comprises, by weight, 20 to 30 parts of a diamine chain extender, and 25 to 35 parts of a solvent. The inert glass bead explosion-proof heat-insulation paint possesses excellent fire resistance and freezing and thawing resistance, is capable of providing thermal insulation boards coated with the inert glass bead explosion-proof heat-insulation paint with relatively high compressive strength, and relatively excellent heat insulation performance, flame resistance, and explosion resistance.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to an explosion-proof and heat-insulating coating of inert vitrified microbeads. 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 joints. 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, prefabricated structures adva...
