复合无机防火涂料优配研究

以市售无机膨胀型AB牌防火涂料为研究基础,复合了膨胀阻燃剂(APP-MEL-PER阻燃体系)、抑烟剂和助剂,进行了新型防火涂料的制备,当膨胀阻燃体系(APP-MEL-PER阻燃体系)以17∶6∶6的配比混合于该涂料中,其所占质量百分比为19%的时,防火性能最好。测试表明,该新型防火涂料烟密度等级6.77,指数下降了10,接近于国家标准1级。在248℃~400℃期间失重仅为12%,在390℃,有强烈的吸收峰,也表现了优异的阻燃性能。实现了APP-MEL-PER膨胀阻燃剂和AB牌涂料优配的目的。

Study on Optimization Confection of Inorganic Compound Fire-resistant Coatings

Taking the AB-branded inorganic intumescent fire-resistant coatings in market as a basis, a new type of fire-resistant coating was prepared by compounding some intumescent flame-retardant material (APP-MEL-PER retardant system), smoke-retardant material and other supporting materials. When the intumescent flame-retardant material was compounded into this new type of coating in a ratio of 17 to 6 to 6 and its mass percentage is 19%, the new type of coating had the best performance of fire-resistance. Test shows that smoke density level of this new coating is 6.77; its index reduces 10 and approaches to the first level of national standard. Besides, It also shows that the new coating has a good effect on inflame-retarding between 248℃ and 400℃, the loss gravimetric rate is only 12%, and there is an intensive absorption peak at 390℃. Thus, the confection of a new type of coating is optimized.
