Abstract
The invention relates to the technical field of adhesive, and specifically relates to a high-performance epoxy adhesive. The epoxy adhesive is composed of the materials in parts by weight: 80-100 parts of epoxy resin, 10-30 parts of liquid butadiene-acrylonitrile rubber, 2-10 parts of a curing accelerator, 6-12 parts of dicyanodiamine, 15-30 parts of calcium carbonate, 15-30 parts of silicon micro-powder, 4-8 parts of fumed silica, 0.1-2 parts of a silane coupling agent, and 2-10 parts of a curing promoter. The invention aims to provide the high-performance epoxy adhesive.
Description
Technical field
The present invention relates to the technical field of tackiness agent, specifically a kind of high-performance epoxy adhesive.
Background technology
Take epoxy resin as the tackiness agent of base-material, the bonding various metals of energy and non-metallic material, it has good processing characteristics, excellent mechanical property, electrical property and chemical resistance.After unmodified epoxy resin cure, because fragility large (elongation at break about about 4%) limits its use.In order to overcome this shortcoming, people carry out flexibilizing epoxy tackiness agent with elastomerics for a long time.The method of modified epoxy is a lot, but to add elastomerics and thermoplastics carries out modified toughened method.But being separated of elastomerics and epoxy resin occurs elastomer-modified method in the solidification process of tackiness agent in the past, elastomerics forms disperse phase, the energy-absorbing when system is subject to impacting, thus the object reaching toughening modifying.Along with the increase of engineering adhesive demand, at present its Research Requirements is increased.
Summary of the invention
The object of the invention is to be to provide a kind of high-performance epoxy adhesive.
The technical solution used in the present invention is, a kind of high-performance epoxy adhesive, described material is by weight ratio: epoxy resin 80-100 part, liquid acrylonitrile butadiene rubber 10-30 part, curing catalyst 2-10 part, Dicyanodiamide 6-12 part, calcium carbonate 15-30 part, silicon powder 15-30 part, aerosil 4-8 part, silane coupling agent 0.1-2 part, curing catalyst 2-10 part.
Say further, described silane coupling agent is KH550, KH560 or KH570.
Say further, described curing catalyst is the one or more combination thing in 2-heptadecane base imidazoles, 2-phenylimidazole, 2-ethyl-4-methylimidazole, 2-phenyl-4-methylimidazole, 2-hendecane base imidazoles, 3-phenyl-1,1-dimethyl urea.
Advantage of the present invention is that toughness is high, good springiness, cementability are good.
