Abstract
The invention discloses a fast-curing epoxy resin adhesive. The fast-curing epoxy resin adhesive comprises components A and components B. The components A are prepared from, by weight, 15-30 parts of epoxy resin, 60-80 parts of nitrile rubber and 5-15 parts of a fire-retardant agent. The components B are prepared from, by weight, 40-60 parts of polyamine, 35-50 parts of glycidyl ether and 5-10 parts of an accelerant. The matching ratio of the components A to the components B is 100:30-40. Due to the mode, the prepared adhesive is short in room temperature curing time and meanwhile has good heat resistance, high stripping strength and flame retardant performance.
