Title:
NOVEL INTUMESCENT FIREPROOF FLAME-RETARDANT SYSTEM, COATING, FLAME RETARDANT AND SIZING AGENT
Document Type and Number:
WIPO Patent Application WO/2022/027922
Kind Code:
A1
Abstract:
A novel intumescent fireproof flame-retardant system, a coating, a flame retardant, and a sizing agent. A carbon source in the flame-retardant system is a phenolic resin, an acid aldehyde epoxy resin, PPO polyphenyl ether and/or polyphenylene sulfide (PPS), an acid source is aryl phosphate ester, and the aryl phosphate ester is RDP, DMP, TPP and/or BDPO. The fireproof intumescent system is formed by reducing a conventional ternary carbon source, an acid source and a gas source to be binary, the acid/gas source is an acid flame retardant, gas is generated in a thermal decomposition reaction process, and the gas and gas generated by the carbon source serve as a gas source together. Weather resistance, durability and other weak points of the existing intumescent flame-retardant systems are improved, and the intumescent flame-retardant system can be widely applied to fireproof coatings and flame-retardant products.
