The present invention provides a flame-retardant resin composition, a thermosetting resin composition, a flame-retardant engineering plastic and a composite metal substrate. The flame-retardant resin composition comprises 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, phosphorus-containing flame retardant and nitrogen-containing flame retardant in the flame-retardant resin composition of the present invention play a synergistic effect, making the prepared copper clad laminate have good flame retardancy, and also good heat resistance, water resistance, adhesion, mechanical properties and electrical properties, and making the prepared engineering plastic have good flame retardancy and good mechanical properties, and thus the flame-retardant resin composition of the present invention is a kind of flame-retardant composition with large economy and friendly environment. |
