摘要
利用乳液聚合法制备了一种含KAl(OH) 2 CO3 纳米粒子的聚苯乙烯 /丙烯酸丁酯复合物 .Zeta电位、粒径分布、扫描电镜 (SEM)和透射电镜 (TEM)等分析表明KAl(OH) 2 CO3 粒子能够稳定地分散于苯丙乳液的乳胶粒中 ,形成核 -壳结构 .热失重 (TG)分析表明KAl(OH) 2 CO3 粒子的加入能提高复合物的热稳定性 。
A P(St/BA) latex containing KAl(OH)(2)CO3 nano particles was prepared by emulsion polymerization method. The results of Zeta potential analysis, particle size analysis, scanning electron microscopy (SEM) and transmission electron microscopy (TEM) confirm that KAl(OH)(2)CO3 nano particles are well dispersed in the latex particles and show a core-shell structure. The enhanced thermal stability of the composites was measured by thermogravimetric analysis (TGA) and indicated that the developed nanocomposite has higher decomposition onset temperature. The resulting latex may have potential application for flame-retarded paints.
