▎ 摘  要

NOVELTY - A polyethylene corrugated pipe comprises 45% polyethylene, 5% bisphenol A type polycarbonate, 5% compatibilizer, 5% polypropylene, 3% rigid masterbatch, 2% antioxidant, 5% light stabilizer, 5% graphene, 5% silane coupling agent, 2% 3-acetylamino-5-methylisoxazole, 3% light-shielding agent, and 15% engineering plastic. USE - Polyethylene corrugated pipe is useful as flexible pipe for automobile exhaust. ADVANTAGE - The polyethylene corrugated pipe has normal-temperature ring rigidity improved by 20% and 45-70 degrees C-ring-rigidity improved by 30%, when compared with existing polyethylene pipe. The normal-temperature ring flexibility is increased by 15% and service life is prolonged.
