摘要
采用溶胶-凝胶工艺制备γ-缩水甘油醚丙基三甲氧基硅烷/正硅酸乙酯(GPTMS/TEOS)杂化材料,采用正交实验法对H2O与S i的摩尔比、GPTMS与TEOS摩尔比、水解时间等影响材料性能的因素进行了优化,用热失重(TGA)和动电位扫描法研究分析了该材料的结构、耐热及防腐保护性能。结果表明:当GPTMS∶TEOS=1∶3(摩尔比),H2O∶S i=11.25∶1(摩尔比)时,该材料的耐热性及防腐保护性能最优,X射线衍射分析表明,该材料结构为非晶态结构。
γ-Glycidoxypropyltrimethoxysilane/tetraethylorthosilicate （ GPTMS/TEOS ） hybrid materials was made by sol-gel process. The influencing factors on the hybrid materials：the mole ratio of H2O to Si, GPTMS to TEOS and hydrolysis time were optimized with orthogonal test. The structure, heat resistant and corrosion protection performance of the materials were researched by thermogravimetric analysis （TGA） and potentio dynamic scan （PDS）. The results showed that the heat resistant and corrosion protection performance of the materials are most excellent when GPTMS： TEOS （mole ratio） = 1：3 and H2O： Si = 11.25： 1. Meanwhile the X-ray diffraction （XRD） analysis indicated that the structure of the materials is amorphous.
