epoxy adhesive and a preparation method thereof, the
epoxy adhesive is composed of a component A and a component B. The component A comprises epoxidized gutta-percha, liquid
epoxy resin, a
reactive diluent, an auxiliary agent and the like, and the component B comprises a
cardanol modified
phenolic aldehyde amine curing agent, a modified
polyamide curing agent, vegetable
oleic acid, an auxiliary agent and the like. The gutta-percha modified second-order reaction
epoxy adhesive disclosed by the invention has the characteristics of second-order reaction characteristic, high flexibility, high
bonding strength, greenness, environment friendliness, reproducibility and the like, and is suitable for waterproof bonding between steel and concrete base planes of roads, bridges and the like and
asphalt pavement
layers.
