▎ 摘　　要

NOVELTY - Aluminum-based composite material comprises 11-18 pts. wt. polyurethane, 34-59 pts. wt. alumina, 21-29 pts. wt. aluminum hydroxide, 12-21 pts. wt. silica, 4-9 pts. wt. titanium oxide, 11-29 pts. wt. sodium alginate, 21-30 pts. wt. graphene, 12-19 pts. wt. nano aluminum, 21-30 pts. wt. copper plated steel fiber, 40-60 pts. wt. polyethylene glycol, 45-68 pts. wt. hydrophilic polymer compound, 1-9 pts. wt. sodium salicylate, 1-8 pts. wt. sodium cellulose, 2-8 pts. wt. quartz sand and 0.1-2.8 pts. wt. grafting agent. USE - The aluminum-based composite material is useful for hollow glass (claimed). ADVANTAGE - The aluminum-based composite material has excellent composite material compressive strength, strong corrosion resistance, and simple and easy preparation method; and is suitable for industrial production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation of aluminum-based composite material comprising (i) adding graphene and copper plated steel fibers into a ball mill grinding into the reactor, then adding silica and titanium oxide, melting the nano-aluminum and magnetic stirring into the single-screw extruder to obtain modified nano-aluminum, (ii) mixing polyurethane, alumina, aluminum hydroxide, polyethylene glycol, sodium salicylate, sodium alginate and deionized water, heating at 50-85 degrees C for 10-30 minutes, and vacuum spray drying to obtain fine powder, and (iii) mixing the modified nano aluminum, fine powder, sodium cellulose, hydrophilic polymer compounds, quartz sand and grafting agent, and adding into the granulator and granulating to obtain final product.
