▎ 摘　　要

NOVELTY - Polyethylene protective film flame retardant modified material comprises 100 pts. wt. polyethylene, 30 pts. wt. talc, 5 pts. wt. plasticizer, 6-14 pts. wt. main flame retardant, 3-7 pts. wt. auxiliary flame retardant and 0-1 pts. wt. graphene micro sheet. USE - The modified material is useful for automobile industry (claimed). ADVANTAGE - The material has tensile strength; impact toughness; has simple preparation; good stability, but also provides a new environmentally-friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing polyethylene protective film flame retardant modified material comprising (i) adding the polyethylene, talc and plasticizer and premixing and mixing graphene micro sheet, melting under the temperature 80-170 degrees C, extruding and pelletizing to obtain the modified polyethylene granules, (ii) usinf flame-retardant modified polyethylene granules melt mixing, heating, cutting to obtain the polyethylene protective film flame retardant modified material.
