Abstract
The invention discloses a halogen-free phosphate-free flame-retardant unsaturated polyester resin composition. The invention is characterized in that the composition is prepared by mixing the following components in parts by mass: 60-80 parts of halogen-free phosphate-free unsaturated polyester resin, 20-40 parts of benzoxazine resin, 35-50 parts of diluter, 80-110 parts of inorganic filler, 1-3 parts of initiator, 2-4 parts of curing agent, 5-15 parts of low shrink agent and 5-10 parts of mold release agent. The halogen-free phosphate-free flame-retardant unsaturated polyester resin composition has the characteristics of high heat resistance, high mechanical strength, halogen-free phosphate-free flame retardancy, low specific gravity, low cost and the like, and can be used for preparing unsaturated polyester molding compound boards, unsaturated polyester glass cloth laminated boards, unsaturated polyester glass felt boards, unsaturated polyester glass plaid boards, unsaturated resin bulk molding compound products or the like. The product is applicable to the fields of transportation vehicles, yachts, buildings, shipbuilding, chemical equipment, electronics and electricity, sports equipment, daily equipment and the like.
