Abstract

The invention relates to a high-glow wire halogen-free flame-retardant polyamide compound. The components of the compound are: 40-90% of polyamide resin, 2-25% of organic phosphinate flame retardant by weight percentage, 1-40% of melamine flame retardant, 1-10% of phosphate ester flame retardant, 0-45% of reinforcing agent, and 0.1-3% of other additives, wherein the total weight of the above components is 100%. The invention aims to provide a polyamide compound with high glow wire performance, high flame retardant performance, halogen-free and environmental protection, and the glow wire performance and flame retardant performance of the polyamide compound can be significantly improved by adding a phosphate ester flame retardant.

Description

technical field [0001] The present invention relates to the technical field of halogen-free flame-retardant plastics, in particular to halogen-free flame-retardant polyamide compounds and moldings comprising the halogen-free flame-retardant polyamide compounds. Background technique [0002] Many plastics are very easy to burn 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 generate 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 more and more popular among researchers and consumers. [0003] Polyamide resins are widely used in home appliances, electricity, electronics, aviation, automobiles and other fields due t...
