超薄型防火涂料的研究

确定了起膨胀阻燃作用的成炭剂、发泡剂以及成炭催化剂组成的阻燃体系，3种主要成分的配合比例为：催化剂质量分数在40％～60％、成炭剂质量分数10％～20％、发泡剂质量分数30％～40％，阻燃效果最佳。苯丙乳液聚合的最佳条件是：软硬单体配比为1：1，所占比例45％；乳化剂1．25％；非离子乳化剂与阴离子乳化剂比为4：1；引发剂用量为0．2％；反应温度控制在（85±1）℃。

Study on Super-thin Fireproof Coating

A flame -retardant system including charring agent, foaming agent and char forming catalyst was determined. When ratio of three main components was as follows：mass fraction of catalyst 40% -60% , mass fraction of charring agent 10% - 20% and mass fraction of foaming agent 30% -40% ,flame- retardant effect was the best. The best condition for styrene- acrylic emulsion was as follows ： ratio of hard and soft monomer was 1 ： 1, and mass fraction of them was 45 % , emulsifier was 1.25 % , ratio of non - ionic emulsifier and anionic emulsifier was 4 ： 1, amount of initiator was 0.2%, reaction temperature was at （ 85 ±1 ） ℃.
