Refractory coating

Abstract

The invention relates to the technical field of coatings, in particular to a refractory coating which is prepared from, by weight, 10-15 parts of epoxy resin, 1-2 parts of yttrium oxide powder, 9-15 parts of aluminum oxide powder, 8-12 parts of quartz powder, 20-30 parts of aluminum silicate, 8-15 parts of silicon dioxide powder, 1-3 parts of barium sulfate, 1-3 parts of coupling agents, 20-30 parts of methylbenzene, 10-20 parts of rare-earth phosphates, 15-25 parts of aluminum triphosphate, 4-5 parts of melamine phosphate, 5-10 parts of sodium hydroxide, 1-8 parts of hydrochloric acid, 1-3 parts of associative polyurethane thickening agents, 1-3 parts of ferroferric oxide, 2-6 parts of zirconium oxide, 1-2 parts of boron nitride powder, 10-15 parts of silicon carbide powder, 1-4 parts of leveling agents, 4-5 parts of defoaming agents and 15-30 parts of water. The refractory coating has the advantages of good heat retaining property, fire resistance and abrasion resistance, strong high-temperature resistance and corrosion resistance, and good viscosity and leveling property.

Architectural coatings are indispensable decorative and protective materials in the construction industry. They are used to coat buildings, decorate buildings or protect buildings. Floor coatings and roof coatings, but the exterior wall architectural coatings in the prior art generally have the following problems. First, the thermal insulation performance of the coating is relatively poor. In cold winter or hot summer, it cannot play a good thermal insulation effect. , followed by high temperature resistance and poor corrosion resistance. After long-term use, the exterior wall coating is gradually corroded or removed due to the wind erosion of high-rise buildings, which seriously affects the appearance and quality of the exterior wall. The phenomenon of de-powdering is ubiquitous, the phenomenon of sagging occurs during painting, and the coating film is easy to crack; moreover, the existing coatings have insufficient fire resistance
