Abstract

The invention discloses an epoxy resin curing agent with a high curing reaction rate. The epoxy resin curing agent is composed of the following components in parts by weight: 19 parts of anhydride mixture, 13 parts of alumina, 11 parts of isoprene, 5 parts of n-butanol glycerol ether, 4 parts of asbestos fiber, 7 parts of polypropylene glycol diglycidyl ether and 0.5 part of phenyl glycidyl ether. The epoxy resin curing agent provided by the invention is high in curing reaction rate, and the completely curing time of the epoxy resin can be reduced to 5 hours.

Description

technical field [0001] The invention relates to an epoxy resin curing agent with fast curing reaction rate. Background technique [0002] Epoxy resin is an amorphous viscous liquid, which becomes plastic when heated, has no obvious melting point, becomes soft when heated, gradually melts and becomes sticky, insoluble in water, and will not harden itself, so it has almost no independent use value. Epoxy resin curing agent is an additive that chemically reacts with epoxy resin to form a network-like three-dimensional polymer, envelops the composite material in the network, and makes the linear resin into a tough body-shaped solid. When a certain amount of curing agent is added to the epoxy resin, it will gradually cure. Due to the good mechanical strength and insulation properties of epoxy resin after curing, epoxy resin is widely used as an adhesive in the manufacture of electronic products. For example, epoxy resin is needed to glue and cure some electrical components on ci...
