▎ 摘　　要

NOVELTY - A polyformaldehyde composite material comprises 90-110 pts. wt. polyformaldehyde, 0.5-10 pts. wt. modified white graphene, 10-20 pts. wt. flame retardant, 0.1-1 pt. wt. antioxidant and 0.1-1 pt. wt. stabilizer (A). The modified white graphene is polymer coated modified white graphene. The polymerized monomer of polymer is a styrene or acrylate monomer. USE - Polyformaldehyde composite material. ADVANTAGE - The polyformaldehyde composite material has excellent flame retardance and mechanical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of polyformaldehyde composite material, which involves uniformly mixing polyformaldehyde, modified white graphene, flame retardant, antioxidant, and stabilizer (A), melt extruding, and granulating.
