Abstract

The invention provides a halogen-free filling flame-retardant nylon 6 composite material and a preparation method thereof. The halogen-free filling flame-retardant nylon 6 composite material provided by the invention is characterized by being prepared from the following raw materials: 53-70 parts by weight of nylon 6 resin, 7-15 parts by weight of melamine cyanurate, 20-30 parts by weight of inorganic filling material, 0-5 parts by weight of synergistic flame retardant, and 1-5 parts by weight of processing agent. Compared with the prior art, the halogen-free filling flame-retardant nylon 6 composite material provided by the invention has the beneficial effects the halogen-free filling flame-retardant nylon 6 composite material is capable of passing the GWFI (Glow Wire Flammability Index) test at 960 DEG C, also has the characteristics of being low in cost, high in modulus and strength, excellent size stability, environment-friendly, flame-retardant and the like, and has good application prospect.

Description

Technical field [0001] The present invention relates to the field of preparation methods of polymer flame-retardant materials, and in particular to halogen-free filled flame-retardant nylon 6 materials and preparation methods thereof. Background technique [0002] With the development of the electronic and electrical industry, the demand for flame-retardant nylon materials continues to grow rapidly. Although halogen-containing flame retardants have good flame retardant effects, they produce large amounts of smoke when burned and produce toxic gases that cause secondary pollution. Melamine cyanurate, referred to as MCA, is a nitrogen-containing compound formed by the polymerization of melamine and cyanuric acid. As a nitrogen-based flame retardant, it has lower toxicity than halogen-based flame retardants and has excellent comprehensive flame retardant properties. Nylon 6 is an important engineering plastic with good toughness, excellent electrical properties, oil resistanc...
