Abstract

The invention discloses a halogen-free flame-retardant nylon 6 material and a preparation method thereof, which belong to the technical field of polymer materials. The material is prepared from the following raw materials: a nylon 6 raw material, a heat stabilizer, an antioxidant, a halogen-free flame retardant, a processing modifier, an inorganic powder filler, fiberglass and pigment. The preparation method comprises the following steps of measuring the raw materials, mixing various raw materials fully and evenly through a high-mixing machine, and preparing a nylon 6 major material; and extruding the nylon 6 major material through an extruder for granulation and forming the halogen-free flame-retardant nylon 6 material. The halogen-free flame-retardant nylon 6 material has the advantages of good mechanical properties, flame retardancy, high-temperature resistance, capability of being widely applied to electrical-appliance components, control switches, rotary switch timers and the like, and better flame-retardant effect compared with the prior halogen-containing flame retardant, as well as no carcinogenic substances in production process and final products.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a halogen-free flame-retardant nylon 6 material and a preparation method thereof. Background technique [0002] Traditional halogen-containing flame retardants can make materials achieve good flame-retardant effects, but they will cause "secondary disasters" due to the release of a large amount of smoke and hydrogen halide gas that irritate the eyes and respiratory system. In particular, polybrominated diphenyls (PBDB) and polybrominated diphenyl ethers (PBDBE) will produce dioxins, which may cause metabolic disorders in the human body and cause nervousness, insomnia, headache, eye diseases, arteriosclerosis, liver tumors and other symptoms , found in animal experiments to cause cancer. On the other hand, it is also quite difficult to dispose or recycle these halogen-containing waste materials, so the use of halogen-containing flame retardants is greatly restricted. H...
