Abstract
The invention relates to the technical field of curing agents, particularly an epoxy resin curing agent. The epoxy resin curing agent comprises the following components in percentage by weight: 40-50% of acid anhydride, 40-50% of boron trifluoride, 5-10% of toughener and 5-10% of diluter. The components above are adopted in combination with any one toughener of carboxyl liquid nitrile-butadiene rubber, carboxyl-terminated liquid nitrile-butadiene rubber, polysulfide rubber, liquid silicone rubber and the like, or any one diluter of polypropylene glycol diglycidyl ether, phenyl glycidyl ether and ethylene glycol diglycidyl ether to further improve the toughness of the epoxy resin curing agent and enhance the bearing strength and temperature tolerance. Therefore, the prepared epoxy resin curing agent has the advantages of high reaction speed, low toxicity, high pressure resistance, corrosion resistance, small shrinkage deformation and the like, and can be widely used in the industries of electrical potting and packaging, electrical casting, electric apparatus impregnation, insulating composite material winding, pulling and extrusion, and the like.
Description
Technical field
The present invention relates to the solidifying agent technical field, be specifically related to a kind of epoxy curing agent.
Background technology
In the prior art, as bonding low-molecular-weight polyamide resin mostly be room temperature curing type at present both at home and abroad commonly used based on epoxy resin bonding.The tackiness agent of this room temperature curing type epoxy curing agent of adapted have adhesion technique simple, need not impressed pressure, the advantage such as can solidify at normal temperatures.But the curing reaction speed of this conventional adhesive is slower, and inapplicable sharp work can't be satisfied the quick-binding of building trade, the many-sided demands such as quick embedding location on the mechanical electric apparatus industry production streamline.
Summary of the invention
The purpose of this invention is to provide that fast, the sinister property of a kind of curing reaction speed is low and high pressure resistant, corrosion-resistant, shrinkage strain circlet epoxy resins solidifying agent.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: a kind of epoxy curing agent, and the component of described epoxy curing agent is, weight percent: acid anhydrides: 40～50%, boron trifluoride 40～50%, toughner 5～10%, thinner 5～10%.
Further, described toughner is carboxyl liquid acrylonitrile butadiene rubber, carboxyl end of the liquid acrylonitrile-butadiene rubber, thiorubber, liquid silastic, polyethers, polysulfones, polyimide, nano-calcium carbonate or nano titanium oxide.
Further, described thinner is polypropylene glycol diglycidyl ether, phenyl glycidyl ether or ethylene glycol diglycidylether.
The present invention has following beneficial effect: a kind of epoxy curing agent of the present invention, the component of described epoxy curing agent and weight percent are: acid anhydrides: 40～50%, boron trifluoride 40～50%, toughner 5～10%, thinner 5～10%, owing to adopt said components, and select simultaneously the carboxyl liquid acrylonitrile butadiene rubber, carboxyl end of the liquid acrylonitrile-butadiene rubber, thiorubber, any one the toughner such as liquid silastic, or polypropylene glycol diglycidyl ether, any one thinner of phenyl glycidyl ether or ethylene glycol diglycidylether, thereby the toughness of further reinforced epoxy solidifying agent, improve loading strength, strengthen heat resistance, thereby the epoxy curing agent of making to have speed of response fast, viciousness is low, and high pressure resistant, corrosion-resistant, the advantages such as shrinkage strain is little can be widely used in electrician's embedding and packing, electrician's cast, the electrical equipment dipping, the industries such as insulating composite material winding and pultrusion.
