▎ 摘  要

NOVELTY - A high-transparency recycled plastic composition comprises 60 wt.% recycled polyethylene particles, 30 wt.% recycled polypropylene particles, 3 wt.% calcium carbonate powder, 2 wt.% graphene powder, 1 wt.% antioxidants, 1 wt.% brighteners, 1 wt.% stabilizers, and plasticizers. USE - High-transparency recycled plastic composition. ADVANTAGE - The composition has high transparency, excellent toughness, good heat resistance, and high production continuity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) preparation of the plastic composition comprising crushing c 60 kg polyethylene reclaimed material and 30 kg polypropylene reclaimed material into pieces or granules and preparing 2 kg calcium carbonate particles, 2 kg graphene powder, and 2 kg liquid plasticizer; mixing recycled polyethylene pellets and recycled polypropylene pellets, stirring, mixing with calcium carbonate, graphene powder, and spraying with plasticizer; heating to 190-200 degrees C and mixing; adding 1 kg antioxidant, 1 kg brightener, and 1 kg stabilizer, mixing, and maintaining temperature at 170-190 degrees C for 80 minutes; extrusion molding and cooling to become rigid plastic strips or rods; cutting into bar or granular shape; and classifying, weighing and packing; and (2) pelletizer comprising box base, mixing stirrer, raw material crushing machine, valve, discharging pipe, heating machine, auxiliary material filling machine, quantitative valve, melt modification tank, continuous screw pump, fixed bottom die, standard template, and extruding outlet.
