Abstract

The invention relates to a glass-fiber-reinforced black halogen-free flame-retardant polyamide composite material, belonging to the technical field of a polymer material. The glass-fiber-reinforced black halogen-free flame-retardant polyamide composite material consists of the following raw materials in parts by weight: 60 to 68 parts of polyamide 610 resin, 12 to 17 parts of polyamide 6 resin, 7 to 11 parts of flexibilizer, 8 to 14 parts of flame retardant, 9 to 18 parts of phosphate, 0.5 to 0.9 part of antioxidant, 23 to 29 parts of reinforcing fibers, and 2 to 3 parts of carbon black. Through test, the glass-fiber-reinforced black halogen-free flame-retardant polyamide composite material has the following performance indexes that the tensile strength is greater than 110 to 150MPa, the bending strength is greater than 200 to 220MPa, the notch impact strength of a cantilever beam is greater than 10 to 14kj / m<2>, and the fire resistance reaches V-0(UL-94-1.6mm).

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a glass fiber-reinforced black halogen-free flame-retardant polyamide composite material. Background technique [0002] Polyamide materials are widely used in various fields of the national economy such as automobiles, construction, electronics, household electrical appliances, and small household appliances. Because polyamide materials will produce a special odor and a certain smoke field when burned, and because the demand for such materials is constantly increasing with the rapid economic growth, it is urgent to make up for the aforementioned disadvantages of polyamide materials. Deficient, to avoid damage to the environment and people when burning [0003] Chinese patent CN101503570A discloses the use of halogen-containing flame retardants to improve the flame retardancy of products, but such materials still produce toxic and harmful substances after th...
