Glass-fiber-reinforced high-flame-retardance PC/PBT composite material for new-energy automobile and preparation method for glass-fiber-reinforced high-flame-retardance PC/PBT composite material

Abstract

The invention discloses a glass-fiber-reinforced high-flame-retardance PC / PBT composite material for a new-energy automobile. The composite material is prepared from the following raw materials in percentage by weight: 4% to 8% of PC resin, 50% to 80% of PBT resin, 2% to 6% of elastomer, 10% to 30% of glass fibers, 3% to 12% of flame retardant and 1% to 5% of flame-retardant assistant. The glass-fiber-reinforced high-flame-retardance PC / PBT composite material for the new-energy automobile, prepared by the method, has excellent rigidity and toughness balance performance and high flame retardance, and the flame retardance can reach a level UL94V0, so that the composite material can be extensively applied to battery shell components, electronic electrical components and the like of new-energyautomobiles, and the field of application of glass-fiber-reinforced PC / PBT materials is greatly widened.

Description

technical field [0001] The invention relates to a glass fiber reinforced high flame retardant PC / PBT composite material for new energy vehicles and a preparation method thereof, specifically a glass fiber reinforced high flame retardant PC / PBT composite material for new energy vehicles that can be applied to automotive functional parts Materials, in the field of polymer modification and processing. Background technique [0002] PC / PBT plastic alloy not only maintains the chemical resistance and easy molding characteristics of crystalline material PBT, but also has the toughness and dimensional stability of amorphous material PC, so its products are widely used in automobile bumpers, automobile handles, electronics, etc. components etc. [0003] However, with the extensive development of new energy vehicles, plastic casings such as battery components have put forward new requirements for materials, requiring materials to have extremely high rigidity and high flame retardancy...
