NOVELTY - A graphene composite is prepared by mixing 100 pts. wt. graphene, 80-100 pts. wt. low-density polyethylene, 10-50 pts. wt. polyethylene wax, 20-40 pts. wt. decabromodiphenyl ether, 1-3 pts. wt. chlorinated paraffin, 3-7 pts. wt. antimony trioxide, 20-40 pts. wt. chlorinated polyethylene, 40-60 pts. wt. aluminum hydroxide, 5-25 pts. wt. zinc borate and 0.5-4.5 pts. wt. silane coupling agent. USE - Graphene composite (claimed). ADVANTAGE - The graphene composite has excellent flame retardance, Shore hardness of 90-100, breaking elongation of 400-600%, tensile strength of 10-20 MPa, oxygen index of 30-50% and breakdown voltage of 20-30 kV/mm, and can be prepared by economical, simple and easy method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene composite.
