Abstract

The invention provides a novel degradable oligomer (polymer) mixed polyamine epoxy resin curing agent and a synthesis method thereof. The curing agent can react with an epoxy resin system to generate a polymerized substance which can be recovered through degradation; the curing agent, the epoxy resin system, reinforcing materials and auxiliary materials can be prepared into a reinforced composite material; and the material can be recovered through degradation. The synthesis method of the degradable oligomer (polymer) mixed polyamine curing agent provided by the invention is mild in reaction conditions, short in production cycle and suitable for industrial mass production; and the cured substance and the reinforced composite material generated by the reaction of the degradable oligomer (polymer) mixed polyamine curing agent and the epoxy resin can be degraded under normal-pressure mild but specific conditions, the degradation process is simple to operate, and industrial mass recovery can be easily realized.

Description

technical field

[0001] The invention relates to the technical field of epoxy resin, in particular to a chemical degradation and recovery of a fiber-reinforced thermosetting epoxy resin composite material. Background technique

[0002] Epoxy resin is widely used in the fields of composite materials, castings, electronic appliances, coatings and adhesives due to its excellent physical and mechanical properties, electrical insulation properties, bonding properties with various materials and its flexibility in use and processing , plays an important role in various fields of the national economy.

[0003] Epoxy resin curing agent is an additive that chemically reacts with epoxy resin to form a network-like three-dimensional polymer, making the linear resin into a tough solid body. As a thermosetting resin, epoxy resin requires a special curing agent when curing. There are many kinds of curing agents, such as basic curing agents, including aliphatic diamines and polyamines, aro...
