摘要
膨胀型防火涂料在阻隔基材迅速升温方面具有明显效果。试验合成了聚苯胺-碳化硅(PANI-SiC)复合材料,通过SEM、FTIR、XRD等手段分析了复合材料的形貌、组成和结构,考察了单组分膨胀型防火涂料乳液的种类及复合材料含量对涂层防火耐火性能的影响。结果表明:醋酸乙烯-乙烯(VAE)乳液相比于苯丙乳液和丙烯酸乳液可以更好地提升涂层的膨胀倍率和耐火性能。随着PANI-SiC含量的增加,涂层的膨胀倍率增加,背面温度降低,10%含量复合材料的防火涂层表现出优异的耐火性能。
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 better 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.
