Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a reinforced flame-retardant PA6 / POK alloy material and a preparation method thereof. Background technique [0002] Nylon 6 (PA6) is widely used in electronic appliances, automobiles, home appliances and other industries. However, caprolactam, the monomer used to produce nylon 6, has certain toxicity and can decompose toxic nitrogen oxides when heated. The production of nylon 6 will cause certain harm to people and the environment in terms of monomer treatment and synthesis process. Therefore, as the domestic environment continues to deteriorate, the state's efforts to improve the environment are gradually increasing, so higher environmental protection requirements are also put forward for manufacturers of nylon 6. This not only increases the manufacturing cost of the enterprise, but also affects the production capacity, which leads to the continuous rise o...
