摘　　要：以树脂和甲基丙烯酸羟丙酯为主要材料,添加气相二氧化硅,辅以促进剂、引发剂等助剂制备了厌氧胶。研究了不同种类和不同比例的树脂、两种引发剂同时使用和单独使用对厌氧胶性能的影响,也考察了厌氧胶的耐介质性,并研究了厌氧胶在不同基材的使用效果。研究结果表明:当树脂为环氧甲基丙烯酸酯树脂且质量分数为50%~60%,两种引发剂结合使用且m(异丙苯过氧化氢)∶m(无味DCP)=2∶1时,其制备的厌氧胶综合性能较佳。经过耐介质性测试,结果表明厌氧胶具有一定的耐水性和耐油性,且厌氧胶在铁制基材的使用效果较佳。Anaerobic adhesive was prepared by using resin and hydroxypropyl methacrylate as main materials,adding fumed silica,supplemented by accelerator,initiator and other additives.The effects of different types and proportions of resin,two initiators used at the same time and separately on the performance of anaerobic adhesive were studied,the medium resistance of anaerobic adhesive was also investigated,and the effects of using anaerobic adhesive on different substrates were studied.The research results showed that when the resin was epoxy methacrylate resin and the mass fraction was 50%-60%,two initiators were used together,and m(cumene hydroperoxide)∶m(tasteless DCP)=2∶1,the comprehensive performance of anaerobic adhesive prepared was relatively good.After the medium resistance test,the results showed that the anaerobic adhesive had certain water resistance and oil resistance,and the anaerobic adhesive was good in the use of iron substrate.
