摘　　要：为改善钡酚醛树脂的耐高温性能和力学性能,本研究采用硅烷偶联剂KH-560对钡酚醛树脂进行化学改性。对改性前后的树脂进行了各项性能表征,重点研究了该改性树脂的热稳定性、力学性能和附着力。研究结果表明:(1)成功地将KH-560通过化学键稳定地连接到钡酚醛树脂的分子链上;(2)KH-560的较佳添加量为15%,相比于纯钡酚醛树脂,改性后钡酚醛树脂的Tmax2提高了约25℃,热性能提升明显;(3)KH-560能够有效改善钡酚醛树脂的力学性能,15%含量的KH-560改性钡酚醛树脂的拉伸强度提高约32.5%,拉伸模量提高约11.7%,附着力提高约30.4%。In order to improve the high-temperature resistance and mechanical properties of barium phenolic resin,silane coupling agent KH-560 was used to chemically modify the resin in this study.Various performance characterizations were conducted on the resin before and after modification,with a focus on the thermal stability,mechanical properties,and adhesion of the modified resin.The research results showed that,(1)KH-560 was successfully and stably connected to the molecular chain of barium phenolic resin through chemical bonds.(2)The optimal addition amount of KH-560 was 15%.Compared with pure barium phenolic resin,the T_(max2)of modified barium phenolic resin increased by about 25℃,and the thermal performance was significantly improved.(3)KH-560 could effectively improve the mechanical properties of barium phenolic resin.The tensile strength of barium phenolic resin modified by 15%of KH-560 increased by about 32.5%,the tensile modulus increased by about11.7%,and the adhesion increased by about 30.4%.
