The present invention provides a flame retardant resin composition, a thermosetting resin composition, a composite metal substrate, and a flame retardant electronic material, wherein the flame retardant composition contains a sulfur-containing flame retardant, a phosphorus- containing flame retardant and / or a nitrogen-containing flame retardant and a halogen-free epoxy resin. The sulfur-containing flame retardant, the phosphorus-containing flame retardant and the nitrogen-containing flame retardant in the flame retardant resin composition of the present invention have a synergistic action, so that the produced copper clad laminate has excellent flame retardancy and excellent heat resistance, water resistance, adhesiveness, The firing sealant produced in the present invention has excellent flame retardancy, shortened surface hardening time, low viscosity, excellent thermal conductivity, and excellent stability. Friendly flame-retardant composition. |
