Application of polyaniline-silicon carbide composites in intumescent flame-retardant coatings
Intumescent flame-retardant coatings are effective in blocking the rapid warming of the substrate.In this experiment,polyaniline-silicon carbide(PANI-SiC)composites were synthe-sized,and the morphology,composition and structure of the com-posites were analyzed by means of SEM,FTIR and XRD,and the effects of the type of one-component intumescent flame-retar-dant 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 bet-ter improve the expansion ratio and flame resistance of the coating compared with phenylpropylene and acrylic emulsion With the in-crease of PANI-SiC content,the expansion ratio of the coating in-creases and the backside temperature decreases,and the fireproof coatings with 10％content of composites show excellent flame re-sistance.
