为了解特种酚醛型环氧树脂的应用特性，通过选取双酚A型、溴化苯酚型、联苯型及三酚型4种特种酚醛型环氧树脂，采用线型酚醛作固化剂，分析了树脂体系的固化反应特性及其覆铜板的耐热性、力学性能与粘结性能。结果表明：联苯型酚醛环氧的反应速度最慢，固化时需较高的温度，制成的覆铜板具有最高的热分解温度、弯曲储能模量与粘结性能，但其玻璃化转变温度却最低；三酚型酚醛环氧树脂具较高的玻璃化转变温度，但失重1%与2%时的热分解温度都最低。
To investigate the application characteristic of special phenolic epoxy resin, using phenolic res-in as curing agent, the curing reaction characteristic of bisphenol A type, brominated phenol type, bi-phe-nyl type and tri-phenol type phenolic epoxy resin and the heat-resistance, mechanical properties and adhe-sion of the copper clad laminate were studied. The results show that the bi-phenyl type phenolic epoxy resin has the slowest reaction speed and requires higher curing temperature, the prepared laminate has the highest thermal decomposition temperature, bending storage modulus and adhesion, but the glass transition temperature shows the lowest. The tri-phenol type phenolic epoxy resin has a higher glass transition tem-perature, but its thermal decomposition temperature at 1% and 2% weight loss shows the lowest.
