摘要:
为了降低双氰胺固化环氧树脂时的固化温度,以二氨基二苯甲烷、双氰胺为原料,蒸馏水作溶剂,盐酸作催化剂制备了一种新型改性双氰胺固化剂. 采用三因素三水平正交实验研究反应时间、反应温度、反应物投料比例对二-(双胍基对苯基)甲烷产率的影响. 结果表明:当反应时间4 h,反应温度120 ℃,二氨基二苯甲烷和双氰胺物质的量比1∶2.15时,二-(双胍基对苯基)甲烷的产率可达85.12%. 用红外光谱、核磁氢谱对化合物化合物结构进行分析并确认. 该法合成的二-(双胍基对苯基)甲烷产物纯净,无副产物产生.
Abstract:
To decrease the curing temperature of epoxy resin with dicyandiamide, a new kind of modified dicyandiamide curing agent was prepared with diaminodiphenylmethane and dicyandiamide as raw materials,distilled water as solvent and hydrochloricacid as a catalyst. The optimum preparation technology of bis- (biguanide-p-phenyl) methane was studied by orthogonal experiments of three factors and three levels. The results show that the yield of bis-(biguanide-p-phenyl) methane is 85.12%at reaction time of 4 h, reaction temperature of 120 ℃, and feed ratio of 1∶2.15. The structures of the compounds were analyzed and confirmed by infrared spectroscopy and hydrogen nuclear magnetic spectroscopy. The modified dicyanodiamide is pure without by-products.
