The invention provides a composite flame retardant, a flame retardant resin composition, a composite metal substrate, a flame retardant electronic material and a flame retardant engineering plastic, the composite flame retardant includes a bromine-containing flame retardant and a sulfur-containing flame retardant And/or a phosphorus-containing flame retardant, the bromine-containing flame retardant is a bromine-containing phenolic compound and an epoxy resin thereof. The bromine-containing flame retardant and the sulfur-containing flame retardant and/or phosphorus-containing flame retardant have a synergistic effect on the flame retardant effect, which can enhance the flame retardant performance of the composite flame retardant, and then enhance the flame retardant performance of the resin composition of the present invention. flammability. The composite metal substrate, flame-retardant electronic material and flame-retardant engineering plastic prepared from the composite flame retardant or flame-retardant resin composition of the present invention have good flame retardancy, good mechanical properties and heat resistance. |
