▎ 摘  要

NOVELTY - High wearable and toughened polybutylene terephthalate (PBT) material comprises 70-90 pts. wt. PBT70, 5-20 pts. wt. wearable agent, 5-10 pts. wt. toughening agent, 0.2-2 pts. wt. compatibilizer, 0.4-2.0 pts. wt. antioxidant, 0.2-1.0 pts. wt. lubricant, 0.1-0.5 pts. wt. graphene composite modified polyimide fiber and 0.1-0.3 pts. wt. ionic liquid composite rare earth liquid. USE - High wear-resistant and toughened PBT material used for automobile inhaul cable. ADVANTAGE - The high wear-resistant and toughened PBT material has high abrasion resistance for automobile inhaul cable. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing wear-resistant toughening PBT material for automobile inhaul cable, which involves: a. weighing raw material; b. adding raw materials to high-speed mixer to mix; c. mixing material by double-screw feeder continuously and uniformly adding into main cylinder of double-screw extruder main machine, where screw diameter is 30 mm, length diameter ratio is L/D=40, controlling each section temperature by section, from feeding port to machine head outlet temperature is 200℃, 220℃, 230℃ or 235℃, double-screw speed is 350 revolutions/minute (rpm); and d. extruding material strip after cooling by cooling water tank, and cutting to obtain high wear-resistant toughening PBT material.
