NOVELTY - High temperature resistant special engineering plastic formulation comprises 35-60 pts. wt. polyphenylene sulfide, 40-60 pts. wt. polyethersulfone, 0.5-0.8 pts. wt. additives, 0.3-0.5 pts. wt. lubricant, 0.3-0.5 pts. wt. antioxidant, 0.1-0.5 pts. wt. silicon-containing flame retardant and 1-5 pts. wt. modified graphene oxide. USE - High temperature resistant special engineering plastic formulation. ADVANTAGE - The high temperature resistant special engineering plastic formulation has good high-temperature adaptability and long-term use. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing high temperature resistant special engineering plastic formulation, which involves: (A) adding high temperature resistant polyphenylene sulfide and polyethersulfone in a reaction kettle; (B) stirring for an hour under the condition of 100 degrees C after after suction filtration; (C) drying at 100 degrees C to obtain the mixed material; (D) controlling the formula ratio and mixing effect of additives, lubricants and modified grapheneoxide through weight loss feeding; (E) adding additive, extruding melted mixed material; (F) controlling the extruding temperature at 300-340 degrees C; (G) putting the lubricant; (H) sending the modified graphene oxide into the mixed material; and (I) conveying and granulating the extruded materialstrips to obtain the cylindrical particles.
