Abstract

The invention discloses a water-based fireproof coating and a preparing method thereof. The water-based fireproof coating is prepared from, by weight, 16-23 parts of ammonium polyphosphate, 8-14 parts of melamine, 7-10 parts of pentaerythritol triacrylate, 10-16 parts of high-chlorinated polyethylene resin, 6-9 parts of polyurethane resin, 4-8 parts of methyl silicone resin, 2-5 parts of sodium carbonate, 17-21 parts of deionized water, 1.5-2.1 parts of a thickening agent, 1.5-4.5 parts of a dispersing agent, 0.22-0.32 part of an antifoaming agent and an appropriate amount of color paste. The water-based fireproof coating has the advantages of being long in flame-retarding time, high in adhesive strength, not prone to cracking, excellent in fire resistance and the like, and is free of toxicity, safe and environmentally friendly.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based fireproof coating and a preparation method thereof. Background technique [0002] At present, water-based fire retardant coatings are mainly organic, inorganic and organic and inorganic composite intumescent fire retardant coatings with excellent performance. Latex type fire retardant coatings use emulsion polymer as base material (emulsion polymer has high relative molecular weight, so it has better mechanical properties as a coating film-former), water is used as solvent, and appropriate types and quantities of additives are added through The coating prepared by grinding, the emulsion commonly used as the base material of water-based fireproof coating includes: polyacrylic acid emulsion, styrene-modified polyacrylic acid emulsion, polyvinyl acetate emulsion, polyvinylidene chloride emulsion, etc. In addition, the selected polymer emulsion must have good adhesion to the su...
