Abstract

The invention relates to the technical field of coatings, in particular to a high temperature-resistant fireproof coating and a preparation method thereof. The high temperature-resistant fireproof coating is prepared from the following raw materials in parts by weight: acrylic resin, inorganic filler, a thickener, a flame-retardant agent, a ceramic additive, fireproof short fibers, a crosslinkingagent, a coupling agent, a flatting agent, a defoaming agent, a wetting agent, a film forming additive, other additives and solvents. The high temperature-resistant fireproof coating has the advantages that high temperature can be endured, the flame-retardant property is good, the propagation of fire condition is well blocked, and the fireproof property is excellent; the effect of resisting long-time impact by 1100 DEG C hydrocarbon high-temperature fire hazard is realized; the weather-resistant property and waterproof property are realized, the shrinkage is avoided, the coating strength is high, and the surface is flat.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-temperature-resistant fireproof coating and a preparation method thereof. Background technique [0002] Building fire prevention is an important field of fire science and technology, and fireproof coating is an important part of fireproof building materials. Fireproof coating refers to coating on the surface of objects, which can prevent fire from happening, prevent fire from spreading or isolate fire source, prolong A type of coating that delays the time of fire of the substrate or increases the thermal insulation properties to delay the time of structural failure. The existing fire retardant coatings have unsatisfactory flame retardant effects and poor high temperature resistance, which restrict the development of the construction field. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the object of the prese...
