Abstract

The invention discloses a flame-retardant nylon 66 / nylon 6 composite material with high mechanical properties. The composite material comprises the following raw materials by weight: 42 to 50 parts ofnylon 66, 10 to 20 parts of nylon 6, 10 to 20 parts of transparent nylon, 0.1 to 0.3 part of a main antioxidant, 0.1 to 0.3 part of an auxiliary antioxidant, 0.1 to 0.3 part of a heat stabilizer, 0.1to 0.3 part of zinc stearate, 2-3 parts of color master batch, 20 to 30 parts of a halogen-free flame retardant and 0.5 to 1 part of an processing auxiliary agent. The composite material provided bythe invention has the following beneficial effects: the obtained composite material has the advantages of higher mechanical properties, excellent flame retardant property, excellent impact resistanceand the like under the condition of meeting a flame retardant condition; meanwhile, the environment-friendly raw materials adopted in the process do not generate substances harmful to human bodies andare free of pollution to the environment.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a flame-retardant nylon 66 / nylon 6 composite material with high mechanical properties. Background technique [0002] Nylon (PA) is the general term for polymers containing amide groups in the repeating unit of the main chain of the macromolecule. It is the variety with the largest output, the most varieties, and the widest application among the five major engineering plastics. There are many varieties of PA, including nylon 6, nylon 66, Nylon 11, Nylon 12, Nylon 46, Nylon 610, Nylon 612, Nylon 1010, etc. Among them, the main varieties are Nylon 6 and Nylon 66, which occupy an absolute dominant position. Nylon 6 has excellent mechanical strength and good wear resistance. Lubricity and chemical resistance, good low temperature performance, easy processing and production, are widely used in engineering plastics, synthetic fibers, packaging materials and other fields; nylon...
