▎ 摘　　要

NOVELTY - Artificial turf filling particles, are claimed. The artificial turf filling particles are prepared by (i) dispersing nano-graphene in deionized water, adding sodium dodecylbenzenesulfonate, then adding hydroxypropyltrimethyl ammonium chloride chitosan, and drying to obtain modified nano-graphene, (ii) crushing the discarded artificial turf particles, washing, and drying and making into discarded artificial turf particles by low-temperature granulation technology, (iii) kneading liquid ethylene propylene diene monomer rubber, adding the modified nano-graphene obtained in step (i), vulcanizing agent and triallyl isocyanurate, and mixing to obtain ethylene propylene diene monomer raw rubber, and (iv) heating and melting the discarded artificial turf particles, then mixing with raw ethylene propylene diene monomer raw rubber, color masterbatch, and light stabilizer, kneading, and drying. USE - The artificial turf filling particles are useful for football field (claimed). ADVANTAGE - The artificial turf filling particles: have excellent antistatic and antibacterial properties; weakens the van der Waals force between graphene sheets and prevents the aggregation of graphene; have two cross-linking and hence graphene exists in the form of network structure in polymer matrix, which reduces the amount of graphene as much as possible while satisfying the antistatic effect and ensures the performance of the product. DETAILED DESCRIPTION - Artificial turf filling particles are claimed. Artificial turf filling particles are prepared by (i) dispersing nano-graphene in deionized water, adding sodium dodecylbenzenesulfonate, then adding hydroxypropyltrimethyl ammonium chloride chitosan and stirring for 30 minutes to obtain mixed solution, and stirring for 2-3 hours, filtering and drying to obtain modified nano-graphene, (ii) crushing the discarded artificial turf particles, washing, drying and making into discarded artificial turf particles by low-temperature granulation technology, (iii) kneading liquid ethylene propylene diene monomer rubber, adding the modified nano-graphene obtained in step (i), vulcanizing agent and triallyl isocyanurate after wrapping rolls, stirring evenly, and mixing to obtain ethylene propylene diene monomer raw rubber, and (iv) heating and melting the discarded artificial turf particles, then mixing with raw ethylene propylene diene monomer raw rubber, color masterbatch, antioxidant, filling oil, inorganic filler and light stabilizer, kneading, extruding, strand drawing, underwater pelletizing or crushing, and drying. An INDEPENDENT CLAIM is included for artificial turf filling particles are prepared by the above method.
