Abstract

The invention discloses flame retardant paint and a preparation method thereof. The flame retardant paint is prepared from, by weight, 70-90 parts of vinyl acetate-acrylate copolymer emulsion, 20-30 parts of styrene-acrylate emulsion, 8-10 parts of cellulose ether, 10-15 parts of glass beads, 3-5 parts of expanded graphite, 3-4 parts of hydrogenated castor oil, 20-30 parts of phenolic propane epoxy resin, 5-6 parts of ammonium polyphosphate, 5-6 parts of pentaerythritol, 2-3 parts of zinc borate, 6-8 parts of butyl latex, 2-3 parts of sodium fluorosilicate, 6-8 parts of quartz sand, 3-5 parts of lignocellulose, 12-15 parts of modified andalusite powder and 10-15 parts of modified kaolin. The flame retardant paint has excellent fire resistance and optical pollution resistance and good weathering corrosion resistance and is good in adhesive strength and wear resistance, not prone to cracking and disengaging on the condition that a large temperature difference exists, excellent and stable in performance, stable in storage, free of toxicity and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a fireproof coating and a preparation method thereof. Background technique [0002] At present, fire retardant coatings are more and more widely used in petrochemical, electric power, industrial and civil construction, machinery and other industries. Fireproof coating is a special coating used on the surface of flammable substrates, which can reduce the flammability of the surface of the coated material, retard the rapid spread of fire, and improve the fire resistance limit of the coated material. However, the existing fireproof coatings have the problems of difficult balance of coating film surface adhesion, cohesive force, burning resistance and weathering corrosion resistance. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a fire-resistant coating, which has excellent anti-burning perform...
