埃洛石固载铂催化合成硅骨架环氧树脂

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93.26%。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0.5~1.5μm,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。

Synthesis of silicone skeleton epoxy resin with platinum catalyst supported halloysite

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.
