Abstract: Intumescent flame?retardant coatings are effective in blocking the rapid warming of the substrate. In this experiment, polyaniline?silicon carbide (PANI?SiC) composites were synthesized, and the morphology, composition and structure of the composites were analyzed by means of SEM, FTIR and XRD, and the effects of the type of one?component intumescent flame?retardant coatings emulsions and the content of the composites on the fire resistance performance of the coatings were investigated. The results show that vinyl acetate?ethylene (VAE) emulsion can better improve the expansion ratio and flame resistance of the coating compared with phenylpropylene and acrylic emulsion With the increase of PANI?SiC content, the expansion ratio of the coating increases and the backside temperature decreases, and the fireproof coatings with 10% content of composites show excellent flame resistance.
