Abstract

The invention relates to a coating, and provides a fireproof coating and a preparation method thereof. The total weight of the fireproof coating is 100%, the fireproof coating is prepared from 65 to 79 percent of polycarbonate polyurethane emulsion; 0.5%-1.5% of a wetting dispersant; 0.5%-2.0% of a defoaming agent; 0.5%-1.5% of a polyurethane thickening agent; 0.1%-0.3% of a cellulose thickener, 0.5%-1% of a wetting leveling agent, 0.2%-0.5% of an adhesion promoter, 0-1.5% of matting powder, 0.3%-0.8% of an anti-settling aid, 3%-7% of a coalescing agent, 0.2%-0.5% of a bactericidal mildew preventive, 11%-20% of a flame retardant and 1%-13% of water, wherein the adhesion promoter is selected from a polysiloxane-free non-ionic compound. The fireproof coating has good dispersing performance,storage performance and rheological property, and a paint film formed by the fireproof coating is flat and smooth, excellent in adhesive force, good in flame retardant property, strong in wrapping property, high in hardness and good in chemical resistance.

Description

Technical field [0001] This application belongs to the technical field of coatings, and in particular relates to a fire-resistant coating and a preparation method thereof. Background technique [0002] Fire is one of the most common disasters in society nowadays. Most of the home decoration materials are wood products and PVC plastic sheets, which are flammable, so the home improvement coating market has a greater demand for fire retardant coatings. However, the existing fire-retardant coatings have poor versatility and are often only suitable for a single substrate. Oil-based coatings are often applied to the oily coating of the substrate. When the polarities of the fire-retardant coating and the substrate are different, adhesion is likely to occur. Poor problem. Summary of the invention [0003] The purpose of this application is to provide a fireproof coating and a preparation method thereof, aiming to solve the problem that the existing fireproof coating has poor versatility ...
