本发明系一种一液型硬化性树脂组成物，其系至少(A)分子内具有2个以上环氧基之化合物、(B)分子内具有2个以上硫醇基之化合物、以及(C)下式(I)所表示之咪唑化合物以液态均匀地混合而成，且不含异氰酸酯化合物；其中，式中之m为0或1，n为1~6之整数，R 1 ~R 3 分别独立地为氢原子、碳原子数1~20之烷基或碳原子数6~20之芳基，R 4 为碳原子数1~20之伸烷基、碳原子数6~20之伸芳基、或以-CH2CH2COO-表示之基，当n为1时，R 5 为碳原子数1~20之烷基或碳原子数6~20之芳基，当n为2~6时，R 5 为碳原子数1~20之烃基。;The present invention is a one component curable resin composition. The composition consisting of at least (A) a compound having molecular formula with two or more epoxy groups, (B) a compound having molecular formula with two or more thiol groups, and (C) an imidazole compound as shown in formula (I). The at least three compounds are uniformly mixed as a liquid, and the composition is free from isocyanate compounds. ;In formula (I), m is 0 or 1, n is an integer from 1 to 6, R 1 ~R 3 are independently one of the following: hydrogen, an alkyl group consisting of 1 to 20 carbon atoms, and an aryl group consisting of 6 to 20 carbon atoms. R 4 is an alkylene group consisting of 1 to 20 carbon atoms, an arylene group consisting of 6 to 20 carbon atoms, or a group such as -CH2CH2COO-. When n is 1, R 5 is an alkyl group consisting of 1 to 20 carbon atoms or an aryl group consisting of 6 to 20 carbon atoms. When n is a value from 2 to 6, R 5 is a hydrocarbon group consisting of l to 20 carbon atoms. |
