摘要

酸酐固化型环氧树脂可通过复合材料成型工艺制成风电叶片大梁等结构件，其交联后具有不易降解、不易回收的特点，是风电叶片回收处理的难点之一。甲基四氢邻苯二甲酸苯酐是酸酐固化剂的一种，通过研究不同液体有机胺、不同的催化剂和不同的工艺条件对该酸酐固化的环氧树脂块降解的影响，确定了最佳降解液和降解催化剂组合、降解工艺条件，实现了酸酐固化环氧体系的快速降解。同时还对降解后的产物进行了萃取分离和红外、核磁等检测，确定了回收产物的主要成分，并分析了液体有机胺对酸酐固化型环氧树脂的降解机理，为酸酐固化型环氧树脂的化学回收和再利用提供了新的思路和有益的探索。

Abstract

The anhydride-cured epoxy resin can be made into structural parts such as wind turbine blades and girders by pultrusion process. After crosslinking

it is difficult to degrade and recycle

which is one of the difficulties in the treatment of wind turbine blades. Methyl tetrahydro phthalic anhydride is a kind of anhydride curing agent. The effects of different liquid organic amines

different catalysts and different process conditions on the degradation of epoxy resin block cured by this anhydride were studied

and the best combination of degradation solution and degradation catalyst and degradation process conditions were determined

which realized the rapid degradation of anhydride cured epoxy system. At the same time

the degraded products were extracted and separated

and detected by infrared ray(IR) and nuclear magnetic resonance(NMR)

and the main components of the recovered products were determined. Moreover

the degradation mechanism of the anhydride-cured epoxy resin by liquid organic amine was deduced

which provided a new idea and beneficial exploration for chemical recovery and reuse of the anhydride-cured epoxy resin.
