一种用于粘结工程塑料的快速固化环氧体系及其制备方法
摘要：
本发明涉及高分子材料应用技术领域，公开了一种用于粘结工程塑料的快速固化环氧体系及其制备方法，用于粘结工程塑料的快速固化环氧体系包含单官能的环氧树脂、多功能团的亚克力、聚胺酯修饰的环氧树脂、脂肪族胺类多元胺、三元胺促进剂及非螯合阴离子金属盐，通过对各组分进行优化组合，从而使其能够性能互补，协同配合形成综合性能优越的双组份环氧体系。该固化环氧体系的制备方法为将各个原料按照相应的质量百分比进行混合、加热后分别制得A组份、B组份，再将A组份、B组份按照相应的质量百分比涂抹于工程塑料进行粘结。本发明显著提高了环氧胶对工程塑料的抗剥离强度，缩短了固化时间，降低了亚克力的刺激气味，提高了工程塑料的粘结质量。
摘要（英）：

The invention relates to the technical field of high polymer material application, and discloses a fast setting epoxy system for bonding engineering plastic and a preparing method of the fast setting epoxy system. The fast setting epoxy system for bonding engineering plastic is prepared from monofunctional epoxy resin, multifunctional acrylic, polyamine-modified epoxy resin, fatty amine polyamine, a tertiary amine accelerator and non-chelation anion metal salt. All the components are optimized and combined so as to complement each other in performance and are in synergic cooperation to form the double-component epoxy resin system superior in comprehensive performance. The preparing method of the fast setting epoxy system comprises the steps that all the raw materials are mixed according to the corresponding mass percentage and heated to obtain a component A and a component B, and then the component A and the component B are smeared to engineering plastic for bonding according to the corresponding mass percentage. By means of the fast setting epoxy system for bonding engineering plastic and the preparing method of the fast setting epoxy system, the peel resistance strength of epoxy glue to engineering plastic is obviously improved, the setting time is shortened, the pungent odor of acrylic is reduced, and the bonding quality of engineering plastic is improved.
