摘　　要： 以天然纳米管状埃洛石为载体，负载氯铂酸制得埃洛石固载铂催化剂，催化1，1，3，3-四甲基二硅氧烷和甲基丙烯酸缩水甘油酯的硅氢加成反应，合成一种硅骨架环氧树脂，产率达到9326％。利用SEM和TEM表征了埃洛石固载铂催化剂的形貌。结果显示，纯化后的埃洛石呈纳米管状结构，管长为0．5～15μm，管外径为50～190nm，管内径为10-20nm，管体清晰，表面干净规整，固载铂催化剂后，催化剂颗粒在埃洛石表面均匀分布。利用红外光谱和氢核磁共振谱对硅骨架环氧树脂结构进行了表征。 The silicone skeleton epoxy resin （SEP） was prepared with the chloroplatinic acid type catalyst supported natural nanotube halloysite through hydrosilylation between 1,1,3,3-tetramethyldisiloxane （TMDS） and 2,3- epoxypropylmethacrylate （GMA）,and the yield of SEP was 93.26%.The morphologies of the platinum catalyst supported halloysite were characterized by SEM and TEM.The results showed that the hallysite had the clear structure ofnanotube with length of 0.5-1.5μm,outer diameter and inner diameter of about 50-190 nm and 10-20 nm respectively after purificating.Moreover,after supporting on the halloysite,the platinum particles were uniformly dispersed on the halloysite surface.The chemical structure of the silicone skeleton epoxy resin was characterized by FT-IR and 1^H-NMR spectra.
