NOVELTY - Preparing graphene-quaternary ammonium salt involves preparing allyl modified graphene, the hydroxylation graphene add to 1, 4-dioxane solvent, ultrasonically dispersing for 30-60 minutes, then added acryloyl chloride, under the nitrogen atmosphere 70-90 degreesC oil bath stirring and reacting for 24-36 hours, filtering, absolute ethyl alcohol and deionized water washing, vacuum dry to obtain the allyl modified graphene of the graft polyethylene terephthalate, using 60 Co-ray sources to irradiate the polyethylene glycol terephthalate, then adding the polyethylene glycol terephthalate after irradiation into the isopropanol dispersion of the allyl modified graphene, stirring to react, after finishing the reaction, filtering, washing deionized water vacuum dry graphene the graft polyethylene glycol terephthalate, preparing epoxypropyl dodecyl quaternary ammonium salt, and adding the dodecyl dimethyl tertiary amine into the reaction container. USE - Method for preparing graphene-quaternary ammonium salt for a long-acting anti-bacterial anti-mite bed for fabric mite bed (claimed). ADVANTAGE - The method has an excellent anti-bacterial effect and can avoid dissolving, falling, separating, and so on in the method of repeatedly washing, compared with simple melt blending, and has stronger water washing resistance, the quilt cover, sheet, and another product surface as a mite, and bacterial growth has a very good inhibiting effect, graphene also has good conductivity, because the way of grafting can help the graphene to form good dispersion in the Terylene (RTM: Polyethylene terephthalate) fiber, so it can form a good conductive network, it also has the effect of antistatic. DETAILED DESCRIPTION - Preparing graphene-quaternary ammonium salt involves preparing allyl modified graphene, the hydroxylation graphene add to 1, 4-dioxane solvent, ultrasonically dispersing for 30-60 minutes, then adding acryloyl chloride, under the nitrogen atmosphere 70-90 degreesC oil bath stirring and reacting for 24-36 hours, filtering, absolute ethyl alcohol and deionized water washing, vacuum dry to obtain the allyl modified graphene of the graft polyethylene terephthalate, using 60 Co-ray sources to irradiate the polyethylene glycol terephthalate, then adding the polyethylene glycol terephthalate after irradiation into the isopropanol dispersion of the allyl modified graphene, stirring to react, after finishing the reaction, filtering, washing deionized water vacuum dry graphene the graft polyethylene glycol terephthalate, preparing epoxy propyl dodecyl quaternary ammonium salt, and adding the dodecyl dimethyl tertiary amine into the reaction container, then adding epoxy chloro propane, where the mass ratio of dodecyl dimethyl tertiary amine and epoxy chloro propane is 10:6-12, heating to 60-80 degreesC, stirring and reacting for 4-6 hours, after finishing the reaction decompressing and distilling, to obtain the epoxy propyl dodecyl quaternary ammonium salt, antibacterial of the anti-mite polyethylene glycol terephthalate, adding the graphene of the graft polyethylene glycol terephthalate and epoxy propyl dodecyl quaternary ammonium salt into the torque rheometer melting and mixing to react, after finishing the reaction, cooling, and discharging, namely obtaining the anti-bacterial-mite polyethylene glycol terephthalate, graphene-acarid bed with a long-acting antibacterial quaternary ammonium salt, using the circular spinneret plate to melt spinning the anti- bacterial-acarid polyethylene glycol terephthalate, the spinning winding speed is 3500-4500 m/minutes, the ring blowing wind speed is 0.3-0 5 m/minutes, spinning to obtain the antibacterial anti-acarid Terylene (RTM: Polyethylene terephthalate) fiber than the anti-bacterial-acarid terylene fiber with the cotton fiber dyeing to obtain the graphene-quaternary ammonium salt for long-acting antibacterial anti-acarid bed fabric. An INDEPENDENT CLAIM is included for method for preparing an anti-acarid bed with fabric-acting graphene anti-bacterial and quaternary ammonium salt, which involves preparing the method.
