▎ 摘　　要

NOVELTY - Composite powder comprises attapulgite, graphene oxide, and 5-15 wt.% amino polyethylene glycol isocyanate. USE - The composite powder is used as an additive in the preparation of polymer composite materials (claimed). ADVANTAGE - The composite powder can well improve the mechanical properties and flame retardancy of the halogen-free low-smoke resistance fuel, and has better combustion performance, low smoke density and toxicity, better overall performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the attapulgite-graphene oxide composite powder, comprising mixing and grinding the attapulgite with aminopolyethylene glycol isocyanate and graphene oxide in sequence.
