Problems solved by technology

[0003] Flame-retardant thermal insulation coatings are favored by people because of their good thermal insulation performance. The existing flame-retardant thermal insulation generally adds flame retardants to the basic coatings, and its flame-retardant effect is not ideal. When a fire occurs, there is no substantial flame-retardant effect. effect

Abstract

The invention provides a flame-retardant thermal-insulation nano thick paste coating. The flame-retardant thermal-insulation nano thick paste coating comprises an inner-layer coating and a surface-layer coating, the inner-layer coating comprises inner-layer powder, an adhesive and a regulator; the inner-layer powder comprises aerogel, an expandable inorganic silicate powder material, diatomite, inorganic fibers or / and organic fibers; the surface layer coating comprises surface layer powder, an adhesive and a conditioning agent, and the surface layer powder comprises calcium powder, diatomite and sericite powder. The aerogel daub and the diatomite serve as a heat-preservation flame-retardant layer in a coating outside a workpiece or a wall surface, in a fire environment, the aerogel and the diatomite wrap the surface layer of the ceramic powder which is not expanded, fire is retarded and isolated, along with temperature rise and heat conduction, the ceramic powder is preheated until expansion, the expanded coating is kept intact and does not crack due to fibers, and the thermal insulation effect is achieved. And the coating has the effects of high temperature resistance and flame retardance. Therefore, the nano high-build coating disclosed by the invention has very good flame-retardant and heat-insulating properties. The coating method is simple, the construction controllability is high, and use is convenient.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a flame-retardant and heat-retaining nano thick paste coating and a coating method thereof. Background technique [0002] Building thermal insulation coating is to take measures on the building envelope to reduce the indoor heat of the building to the outside, so as to maintain the temperature of the building indoors and achieve the effect of heat preservation. In recent years, coatings have been very diversified in terms of functions, such as thermal insulation, scratch resistance, corrosion resistance, flame retardancy, etc.; in addition to suspended ceilings, they are also widely used in building walls, wood and other fields. [0003] Flame-retardant thermal insulation coatings are favored by people because of their good thermal insulation performance. The existing flame-retardant thermal insulation generally adds flame retardants to the basic coatings, and its fl...
