Abstract

The invention relates to an epoxy resin toughening agent, which belongs to the technical field of epoxy resins. The toughening agent includes 10-20 parts of 2,4-toluene diisocyanate, 20-25 parts of polyether 210, 10-15 parts of polyethylene glycol, 5-10 parts of m-xylylenediamine, and 20 parts of dimethyl sulfoxide -30 parts, tetrahydrofuran 10-20 parts. The epoxy resin toughening agent has better toughening effect, easy control of reaction operation and relatively low cost.

Description

technical field [0001] The invention relates to a toughening agent, more specifically, the invention relates to an epoxy resin toughening agent, which belongs to the technical field of epoxy resins. Background technique [0002] Epoxy resin has the advantages of high bonding strength, wide bonding surface, low shrinkage, good electrical properties and acid and alkali resistance, and is widely used as adhesives, electrical materials and insulating materials. However, due to the poor toughness, easy cracking and low impact strength of epoxy resin, it is generally toughened and modified when it is used. Amine-terminated polyurethane is an amine-based epoxy resin curing agent containing polyether flexible chain segments synthesized by the reaction of polyurethane prepolymers with common aliphatic or aromatic amines. The amino-terminated polyurethane is used as the toughening agent of the epoxy resin, and through its curing reaction with the epoxy resin, the molecules of the epo...
