摘　　要：将氢化双酚A与环氧氯丙烷反应合成了氢化双酚A型环氧树脂(HBPA-EP),产物分别用多元胺类或酸酐类固化剂固化,利用差示扫描量热分析(DSC)对固化反应特性进行了研究,得到了相应的固化条件、固化反应活化能和固化反应动力学方程等。结果表明,当分别采用1,3-环己二甲胺、液态聚酰胺、顺式六氢苯酐、甲基六氢苯酐固化HBPA-EP(环氧值为0.45)时,其固化条件分别为100℃、2h,145℃、4h,90℃、2h,120℃、4h,130℃、2h,150℃、4h,140℃、2h和160℃、4h,用这4种固化剂进行固化反应的表观活化能分别为50.62、56.88、74.56kJ/mol和68.36kJ/mol,其反应级数分别为0.886、0.901、0.915和0.905。The hydrogenated bisphenol A epoxy resin （HBPA-EP） with an epoxy value of 0.45 was prepared by the reaction of hydrogenated bisphenol A and epichlorohydrin, and was cured with polyamines or anhydrides. The curing properties of the HBPA EP with different hardeners were investigated by DSC, and the curing conditions, apparent activation energies, as well as the reaction kinetic equations were determined. As the result for the hardeners 1,3-cyclohexanedimethanamine, liquid polyamide, cis-hexahy-drophthalic anhydride or methyl hexahydrophthalic anhydride, the curing condition was 100 ℃ ,2 h, 145 ℃,4 h, 90 ℃,2 h, 120 ℃,4 h, 130 ℃,2 h, 150 ℃,4 h, 140 ℃,2 h and 160 ℃,4 h, respectively. The apparent activation energy of curing reaction with the four hardeners was 50.62, 56.88, 74.56, 68.36 kJ/ mol, respectively and the reaction order of the four hardeners was 0. 886, 0. 901, 0. 915, 0. 905, respectively.
