Embodiment 1

[0015] 58 parts by weight of bisphenol A type polycarbonate, 16 parts by weight of epoxy resin, 16 parts by weight of acrylonitrile-butadiene-styrene copolymer, 9 parts by weight of nitrogen-silicon composite halogen-free environmental protection flame retardant and 1 weight part terpolymer of polybutadiene mixed. Then, it is extruded and granulated by a twin-screw extrusion granulator at 230° C. to obtain an environmentally friendly flame-retardant special engineering composite material.

Embodiment 2

[0017] 60 parts by weight of bisphenol A type polycarbonate, 13 parts by weight of epoxy resin, 14 parts by weight of acrylonitrile-butadiene-styrene copolymer, 11 parts by weight of nitrogen-silicon composite halogen-free environmental protection flame retardant and 2 parts by weight terpolymer of polybutadiene mixed. Then, it is extruded and granulated by a twin-screw extrusion granulator at 230° C. to obtain an environmentally friendly flame-retardant special engineering composite material.

Embodiment 3

[0019] 55 parts by weight of bisphenol A type polycarbonate, 16 parts by weight of epoxy resin, 16 parts by weight of acrylonitrile-butadiene-styrene copolymer, 11 parts by weight of nitrogen-silicon composite halogen-free environmental protection flame retardant and 2 parts by weight terpolymer of polybutadiene mixed. Then, it is extruded and granulated by a twin-screw extrusion granulator at 230° C. to obtain an environmentally friendly flame-retardant special engineering composite material.

[0020] It is known through testing that the composite materials prepared in the above examples all have good flame retardancy, and are environmentally friendly, green and non-toxic.

Abstract

The invention relates to the technical field of composite materials, and discloses a novel environment-friendly flame-retardant special engineering composite material. The environment-friendly flame-retardant special engineering composite material contains 50-70% by weight of bisphenol A polycarbonate, 10-20% by weight of epoxy resin, 10-20% by weight of acrylonitrile butadiene styrene copolymer,8-12% by weight of a nitrogen-silicon compound halogen-free environment-friendly flame retardant and 1-3% by weight of a ternary graft copolymer of polybutadiene. The environment-friendly flame-retardant special engineering composite material provided by the invention not only has good flame retardant property, but also has the characteristics of no toxicity, low carbon, environmental protection and greenness.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a novel environmentally friendly flame-retardant special engineering composite material. Background technique [0002] Polycarbonate is a polymer of bisphenol A, which belongs to thermoplastic resin. It is widely used as engineering plastic material, exhibits excellent impact resistance, electrical properties and molding properties, maintains physical properties in a wide temperature range, and has Self-extinguishing. However, it is difficult to use polycarbonate in small-sized and more complicated housings of electric and electronic products due to the disadvantage of poor processability of polycarbonate. In order to solve this problem, the industry adopts the method of blending polycarbonate with other types of resins to improve the processability of the material while maintaining high impact strength. Glass fiber reinforced composite material is a composite mater...
