Abstract

The invention relates to a high-glow-wire halogen-free flame-retardant polyamide compound, wherein the high-glow-wire halogen-free flame-retardant polyamide compound comprises the following componentsin percentage by weight: 40-90% of polyamide resin, 2% -25% of an organic phosphinate flame retardant, 1% -40% of a melamine flame retardant, 1% -10% of a phosphate flame retardant, 0-45% of a reinforcing agent and 0.1-3% of other additives, wherein the total weight of the components is 100%. The invention aims to provide the halogen-free environmentally- friendly polyamide compound with high-glow-wire performance and high flame retardancy, the glow-wire performance and the flame retardancy of the polyamide compound are remarkably improved by adding the phosphate flame retardant.

Description

technical field [0001] The invention relates to the technical field of halogen-free flame-retardant plastics, in particular to a halogen-free flame-retardant polyamide compound and a molding containing the halogen-free flame-retardant polyamide compound. Background technique [0002] Many plastics themselves are extremely flammable due to their chemical composition, so in order to improve the fire resistance of plastics, it is necessary to add certain flame retardants to meet the requirements. When a fire occurs, halogen-containing flame-retardant materials will produce a large amount of smoke and toxic corrosive hydrogen halide gas during the flame-retardant process, causing secondary hazards. Therefore, with the improvement of environmental awareness, halogen-free flame retardant products are becoming more and more popular among researchers and consumers. [0003] Polyamide resin is widely used in household appliances, electric power, electronics, aviation, automobiles an...
