NOVELTY - Automobile handle injection mold material comprises 20-40 pts. wt. polypropylene, 10-20 pts. wt. polyurethane, 2-6 pts. wt. nano aluminum oxide, 4-10 pts. wt. silicon micro powder, 1-3 pts. wt. sepiolite fiber, 3-9 pts. wt. nano chromium powder, 2-6 pts. wt. talc, 1-3 pts. wt. glass fiber, 4-12 pts. wt. polyphenylene sulfide, 2-8 pts. wt. tetraphenyl tin, 3-9 pts. wt. barium sulfate, 1-4 pts. wt. plasticizer, 2-6 pts. wt. lignified plant fiber, 1-3 pts. wt. graphene, 4-12 pts. wt. paraffin, and 1-2 pts. wt. nano silver ion powder. USE - Used as automobile handle injection mold material. ADVANTAGE - The mold material: has excellent pressure resistance, abrasion resistance, impact resistance and aging resistance; and prolongs the service life of the automobile handle. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the automobile handle injection mold material, comprising (i) mixing polypropylene, polyurethane, nano aluminum oxide, silicon micro powder, sepiolite fiber, nano chromium powder and talc, adding in a stirring tank to stir at low speed of 80-120 revolutions/minute for 5 minutes, then adding plasticizer and paraffin, continuously stirring for 8 minutes, and allowing to stand for 10 minutes to obtain mixture A, (ii) orderly adding glass fiber, polyphenylene sulfide, tetraphenyl tin, barium sulfate and lignified plant fiber to the mixture A, uniformly mixing, heating in a water bath at temperature of 60-80 degrees C for 4-10 minutes, and slowly cooling to room temperature to obtain mixture B, and (iii) adding graphene and nano silver ion powder to the mixture B, uniformly mixing, extruding the mixture in a double-screw extruder, and granulating the extruded material in a granulator.
