Abstract

[2-(3,4-epoxycyclohexyl) ethyl] triphenylsilane was synthesized, using triphenylsilane and 1,2-epoxy-4-vinylcyclohexane as the main raw materials. When the molar ratio of triphenylsilane to 1,2-epoxy-4-vinylcyclohexane was 1.0:1.2, the content of Wilkinson catalyst was 0.4%, the reaction temperature was 90°C, and the reaction time was 6 hours, the yield of [2-(3,4-epoxycyclohexyl) ethyl] triphenylsilane could reach 95.21%. The structure of the synthesized product was analyzed and characterized using FT-IR and 1H-NMR. The synthesized product was added to a bisphenol A-type epoxy resin (E-51) and a modified amine (593 amine) to prepare an adhesive. Then, the adhesive was poured into the mold and cured at 35°C for 8 hours. The cured sample exhibited the best performance when the ECETPS: E-51:593 amine molar ratio was 0.8:7.2:2. Thermal gravimetric analysis (TG) showed that the thermal stability of the cured samples increased relative to pure E-51 amine-cured samples with the synthesized product added. The mechanical properties of the samples were tested using a universal material testing machine, and the results showed a tensile strength of 37.95 MPa and a bending strength of 39.10 MPa.

2-(3,4-环氧环己基)乙基]三苯基硅烷的合成及其胺固化特性研究

以三苯基硅烷和 1,2-环氧-4-乙烯基环己烷为主要原料，合成了[2-(3,4-环氧环己基)乙基]三苯基硅烷。当三苯基硅烷与 1,2-环氧-4-乙烯基环己烷的摩尔比为 1.0:1.2，威尔金森催化剂的含量为 0.4%，反应温度为 90℃，反应时间为 6 小时时，[2-（3,4-环氧环己基）乙基]三苯基硅烷的收率可达 95.21%。利用傅立叶变换红外光谱和 1H-NMR 对合成产物的结构进行了分析和表征。将合成产物加入双酚 A 型环氧树脂（E-51）和改性胺（593 氨基）中制备粘合剂。然后将粘合剂倒入模具中，在 35°C 下固化 8 小时。当 ECETPS：E-51：593 氨基酸的摩尔比为 0.8：7.2：2 时，固化样品的性能最佳。热重分析（TG）表明，与添加了合成产品的纯 E-51 氨基化合物固化样品相比，固化样品的热稳定性有所提高。使用万能材料试验机测试了样品的机械性能，结果显示拉伸强度为 37.95 兆帕，弯曲强度为 39.10 兆帕。
