摘要:以巯丙基三甲氧基硅烷(MPS)、双酚A双烯丙基醚(BBA)为原料,通过巯基-烯烃点击反应,生成双硅型硅烷偶联剂(BSC,产率95%)。红外(FTIR)分析表明,反应后原料的双键伸缩振动吸收峰v_(C=C)、v=(C—H)、v_(S—H)均消失,说明发生了反应;核磁分析(~1H NMR)表明产物结构为目标产物BSC。将BSC配制成水解液后加热固化成膜,采用热重分析仪(TGA)、极化曲线法(PCA)、盐雾腐蚀试验(SPT)等方法分析膜层的热稳定性、耐腐蚀等性能。结果表明,BSC膜层热稳定性能优于MPS水解液膜层;极化电阻为17 833Ω/cm^2,腐蚀速率为1.18×10^(-2)mm/a;盐雾加速腐蚀实验表明,BSC的防护性能明显优于MPS;BSC膜层耐冲击性能大于100 cm·kg,耐弯曲性能1级,附着力0级,硬度2H。
A bi-silane coupling agent (BSC) was synthesized with the yield of 95% by reacting 3-mercap- topropyhrimethoxysilane (MPS) with bisphenol A bisallyl ether (BBA). It was proved that BBA reacted with MPS because of the disappearance of the stretching vibration absorption of v c=c ,V=C-H ,VS-H via FFIR. The chemical structure of the compound (BSC) was characterized by 1H NMR. The thermo-stability and corrosion resistance of the cured BSC hydrolysate film were characterized by thermo-gravimetric analysis (TGA), polari- zation curve analysis (PCA) and the salt spray test (SPT), respectively. Thermo-gravimetric analysis shows that the cured BSC hydrolysate film has better thermo-stability than that of MPS. The polarization resistance of the film is 178331Ω/cm^2 and its corrosion rate is 1.18 ×10^-2mm/a by polarization curve analysis. The salt spray test shows that the cured BSC hydrolysate film has more prominent corrosion resistance than that of MPS. The cured BSC hydrolysate film on iron sheet withstands more than 100 cm ~ kg impact and bending level 1. Moreover, its adhesion and hardness grade are 0 and 2H, respectively.
