High-efficiency flame-retardant ceramic particle water-based thermal insulation coating and preparation method thereof

Abstract

The invention provides a high-efficiency flame-retardant ceramic particle water-based thermal insulation coating, comprising a liquid component I, a liquid component II and a solid component which aremixed according to a mass ratio of 7: (0.2-0.4): (3-4). The liquid component I comprises the following components in percentage by mass: 35.0%-55.0% of an acrylate emulsion, 1.5%-3.0% of texanol, 0.5%-1.5% of 2-amino-2-methyl-1-propanol, 0.5%-1.0% of an antifoaming agent, 1.0%-2.0% of a wetting agent, 0.5%-1.5% of a leveling agent, 3.0%-6.0% of a dispersing agent, 10.0%-20.0% of a liquid flame retardant and the balance of water. The liquid component II comprises the following components in percentage by mass: 50% of a thickening agent and 50% of water. The solid component comprises the following components in percentage by mass: 10.0%-20.0% of talcum powder, 5.0%-15.0% of mica powder, 5.0%-15.0% of titanium dioxide, 15.0%-30.0% of heat insulation powder and 30.0%-60.0% of hollow ceramic particles. The flame retardant property of the thermal insulation coating can be remarkably improved, and meanwhile, the thermal insulation property of the coating is not influenced.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a high-efficiency flame-retardant ceramic particulate water-based heat-insulating coating and a preparation method thereof. Background technique [0002] Water-based thermal insulation coatings are mainly composed of acrylate emulsions, water-based additives, and functional solid fillers. This type of water-based coating has the advantages of both waterproof and heat insulation. The coating formed after coating often has high density and good adhesion. Liqiang, by adjusting the proportion of functional solid fillers and emulsions, can meet the requirements of different projects for the strength and flexibility of coating films, and is a product that has developed rapidly in recent years. [0003] Water-based thermal insulation coatings are widely used in thermal insulation projects in buildings, bridges, transportation, offshore drilling platforms, chemical storage tanks, oil pi...

AI Technical Summary

Problems solved by technology

However, since the material used for this type of material is an acrylic emulsion, the coating after film formation usually does not have flame retardant properties. The fuel is modified, but the result of the modification will lead to a decrease in the proportion of functional powder in the system, which will eventually affect the heat insulation effect of the heat insulation coating

As the country pays more and more attention to safety production, the flame retardancy of water-based thermal insulation coatings greatly limits its promotion and application in fields that require certain fire protection ratings.
