▎ 摘　　要

NOVELTY - An alloy based on coating modified carbon method, is a flame-retardant polyphenylene oxide/ high impact polystyrene (PPO/HIPS) antistatic alloy comprising 50-100 pts. wt. polystyrene resin powder, 10-50 pts. wt. polyphenyl ether resin powder, 5-50 pts. wt. phosphorus-containing flame retardant, 0.5-5 pts. wt. conductive carbon, 0.2-2 pts. wt. antioxidant and 0.2-2 pts. wt. lubricant. USE - Alloy, based on coating modified carbon method, is used as antistatic engineered plastic alloy. ADVANTAGE - The alloy, based on coating modified carbon method, has conductive carbon completely ground and dispersed with phosphorus-containing flame retardant, so that the alloy which is a halogen-free flame retardant is easily dispersed and has easy to flow and easy to process properties. The PPO/HIPS antistatic alloys are prepared without the problems of dust dispersion, uneven conduction, and difficulty in processing. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation of alloy, based on coating modified carbon method, which involves: 1) adding carbon into a heating three-roller grinder, setting the heating temperature to room temperature to 150℃, followed by performing coarse grinding three times, then fine grinding twice (roller distance 10μm, 5μm), to form phosphorus-containing flame retardant molecule coated high-dispersion carbon; 2) adding the coated high-dispersion carbon and other raw materials into a high-speed mixer, mixing for 3-30 minutes and forming a mixed material; 3) performing melt extrusion granulation and performing underwater bracing, air drying with a wind bucket, followed by particle cutting mixed melt, with a particle cutting machine.
