【摘要】 利用环氧活性稀释剂乙二醇二缩水甘油醚(商品名JX-21)和环硫化剂硫脲合成了新型的环氧树脂活性稀释剂,并利用红外光谱等手段研究了产品分子结构。该类活性稀释剂和E-44环氧树脂进行复合并以甲基六氢邻苯二甲酸酐(MeHHPA)为固化剂,考察了固化物力学性能、吸水性及玻璃化温度等。更多还原

【Abstract】 A new kind of episulfide-epoxy active diluent was synthesized with ethylene glycol diglycidyl ether(JX-21) and thiourea.The products were characterized by IR spectrum for molecular structure.And using MeHHPA as a hardener and composite the new diluents with epon-44,the cured material’s properties,such as tensile strength,peeling strength,water absorption and glass transition temperature were also investigated.更多还原
