摘要 以正硅酸乙酯(TEOS)、甲基三甲氧基硅烷(MTMS)、二甲基二甲氧基硅烷、有机硅树脂和冰醋酸为原料,通过共聚缩合的方法制备性能优良的甲基体系有机硅树脂封闭剂,研究了该体系中原料配比对封闭剂性能的影响,并对于涂覆于镍板上的封闭剂膜的硬度、耐腐蚀性等进行了分析,利用傅里叶变换红外光谱仪、电化学(EIS、tafel)和扫描电镜对树脂膜进行形貌和结构表征。结果表明,当TEOS与MTMS的摩尔比为1∶0.65、有机硅树脂的质量分数为3%、二甲基二甲氧基硅烷质量分数为5%、pH为4.5时,镍金属板上所成膜的硬度达到5H,盐水浸泡实验能达到96 h。

Abstract: The methyl silicone resin sealant with good performance is synthesized by copolymerization and condensation of tetraethoxysilane (TEOS),methyl trimethoxysilane (MTMS),dimethyl dimethoxy silane,silicone resin and glacial acetic acid.The influences of the molar ratios among raw materials in the reaction system on the performance of sealant are investigated.The hardness and corrosion resistance of sealant film coated on the nickel-plated plate are analyzed and studied.Fourier transform infrared spectrometer,EIS and scanning electron microscopy are used to characterize the morphology and microstructure of resin film.Results show that the hardness of the sealant film formed on nickel-plated plate can reach 5 H and the immersion test in salt solution can reach 96 h when the molar ratio of TEOS to MTMS is 1∶0.65,the mass content of silicone resin in the reaction system is 3%,the mass content of dimethyl dimethoxy silane is 5% and pH of reaction system is 4.5.
