Abstract

The invention discloses an antistatic polyamide composite material and a preparation method thereof. The antistatic polyamide composite is prepared from the following raw materials in parts by weight: 40-50 parts of polyamide, 20-30 parts of polyphenylene sulfide, 20-30 parts of poly (4-vinylpyridine), 30-80 parts of polyimide, 40-60 parts of calcium acetate, 20-30 parts of carbon black, 20-70 parts of sulfur, 30-60 parts of barium sulfate, 4-15 parts of toluene diisocyanate, 10-30 parts of stabilizer, 10-30 parts of titanium dioxide and 40-90 parts of resin. The preparation method comprises the following steps: adding polyamide, polyphenylene sulfide and polyvinyl pyridine in a reaction kettle, uniformly stirring, heating, and raising the temperature to 115-120 DEG C; adding polyimide, calcium acetate, carbon black and sulfur within 15-45min, raising temperature to 200-250 DEG C, and reacting for 1-2h; adding the rest of components, uniformly mixing, and carrying out extrusion pelletizing. The antistatic polyamide composite has surface resistance of 3.2*10<6>-3.8*10<6> omega and arc resistance of 120-125s and also has good antistatic effect.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to an antistatic polyamide composite material and a preparation method thereof. Background technique [0002] Polyamide, the English name is polyamide, referred to as PA. Commonly known as nylon (Nylon), it is the variety with the largest output, the largest variety and the widest application among the five major engineering plastics. The main varieties of nylon are nylon 6 and nylon 66, which occupy an absolute dominant position. Nylon 6 is polycaprolactam, while nylon 66 is polyhexamethylene adipate. Nylon 66 is 12% harder than nylon 6; followed by nylon 11, Nylon 12, nylon 610, nylon 612, and nylon 1010, nylon 46, nylon 7, nylon 9, nylon 13, new varieties include nylon 6I, nylon 9T and special nylon MXD6 (barrier resin), etc., nylon modification Variety. The main varieties are nylon 6, nylon, nylon 11, nylon 12, nylon 610, nylon 612, nylon 4fi, nylon 1010, etc. A...
