The invention relates to the field of plastic composites, and discloses a high-strength coating composition for injection molding, a plastic composite obtained by using the coating composition for injection molding, and a preparation method thereof. The composition of the present invention contains a binder resin, a curing agent A, a curing agent B, a silane coupling agent and a diluent, wherein the binder resin is an epoxy resin; the curing agent A is a tertiary amine curing agent One or more of a solidifying agent, an imidazole curing agent, boron trifluoride and its complex; the curing agent B is an aromatic polyamine, an organic acid hydrazide, an organic acid anhydride, a phenolic resin and an amino resin. One or more; the weight ratio of the curing agent A and the curing agent B is 1:2-6. The plastic composite obtained by using the high-strength coating composition for injection molding of the present invention has extremely high interlaminar bonding force. |
