▎ 摘　　要

NOVELTY - Preparing silicon dioxide-coated zinc borate synergistic graphene multifunctional auxiliary agent comprises (a) dissolving boric acid in deionized water, adding zinc oxide, then adding ammonia while stirring, and adding sodium dodecylbenzenesulfonate, heating at 45 degrees C in a water bath, stirring for 2 hours, filtering and drying at 60 degrees C to obtain zinc borate, (b) adding zinc borate to deionized water, then adding ammonia to obtain a mixed solution, adding mixed solution to the mixed solution containing tetraethyl orthosilicate and absolute ethanol, continuing stirring for 4 hours, filtering, washing with absolute ethanol, and drying at 70 degrees C to obtain silicon dioxide-coated zinc borate, and (c) dispersing silicon dioxide-coated zinc borate in deionized water, ultrasonically oscillating for 30 minutes, then adding graphene, stirring for 1 hour, washing, and drying at 60 degrees C. USE - The multifunctional auxiliary agent is useful in artificial turf filling granular materials (claimed). ADVANTAGE - The multifunctional auxiliary agent: is simple, safe and environmentally friendly; has practical technological process, has flame retardant, wear-resistant, antibacterial property, and has huge social and economic benefits. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: silicon dioxide-coated zinc borate synergistic graphene multifunctional auxiliary agent prepared by the above method; #use of silicon dioxide-coated zinc borate synergistic graphene multifunctional auxiliary agent in artificial turf filling granular materials.
