In this work, a cycloaliphatic epoxy resin hexahydrophthalic acid bis(3,4-epoxycyclohexylmethyl) ester (BE) was prepared and cured with anhydride. The curing kinetics and properties of the cycloaliphatic epoxy resin were characterized and compared with (3′,4′-epoxycyclohexane) methyl-3,4-epoxycyclohexyl-carboxylate (CE) and bis(3,4-epoxycyclohexylmethyl) adipate (BA). The result shows that BE/4-methyl hexahydrophthalic anhydride (MHHPA) exhibits a higher reaction activation energy and a slower curing rate than CE/MHHPA and BA/MHHPA. The loss modulus of BE/MHHPA increased 53 and 24% compared to CE/MHHPA and BA/MHHPA, respectively. The Young’s modulus and initial degradation temperature of BE/MHHPA improved 31 and 6.4% compared with those of BA/MHHPA. Furthermore, superior moisture resistance and dielectric properties are expressed for BE/MHHPA among these epoxy resins. Those results demonstrated the potential usefulness of BE/MHHPA in the electronic packaging materials field.

酸酐固化高性能脂环族环氧树脂的固化动力学和性能
在这项工作中，制备了脂环族环氧树脂六氢邻苯二甲酸双（3,4-环氧环己基甲基）酯（BE）并用酸酐固化。表征了脂环族环氧树脂的固化动力学和性能，并与（3'，4'-环氧环己烷）-3,4-环氧环己基羧酸甲酯（CE）和双（3,4-环氧环己基甲基）己二酸酯（BA）进行了比较。结果表明，与CE / MHHPA和BA / MHHPA相比，BE / 4-甲基六氢邻苯二甲酸酐（MHHPA）具有更高的反应活化能和更低的固化速率。与CE / MHHPA和BA / MHHPA相比，BE / MHHPA的损耗模量分别增加了53％和24％。与BA / MHHPA相比，BE / MHHPA的杨氏模量和初始降解温度分别提高了31％和6.4％。此外，在这些环氧树脂中，BE / MHHPA表现出优异的耐湿性和介电性能。这些结果证明了BE / MHHPA在电子包装材料领域的潜在用途。
