Composite Flame Retardant, Flame Retardant Resin Composition, Composite Metal Substrate, Flame Retardant Electronic Material and Flame Retardant Engineering Plastic

摘要

The present 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, wherein the composite flame retardant comprises a bromine-containing flame retardant, as well as a sulfur-containing flame retardant and/or a phosphorus-containing flame retardant; said bromine-containing flame retardant is a bromine-containing phenol compound and epoxy resins thereof. The bromine-containing flame retardant has a synergistic effect on the flame retardant effect with the sulfur-containing flame retardant and/or the phosphorus-containing flame retardant, thereby enhancing the flame retardancy of the composite flame retardant and further enhancing the flame retardancy of the resin composition of the present invention. Therefore, the composite metal substrate, the flame retardant electronic material and the flame retardant engineering plastic prepared from the composite flame retardant or the flame retardant resin composition of the present invention have good flame retardancy, good mechanical properties and heat resistance.
