NOVELTY - Modified mineral graphene melt blown cloth comprises 60-80 pts. wt. polypropylene, 10-20 pts. wt. toughening agent, 10-15 pts. wt. high carbon alkane, 5-10 pts. wt. graphene materials, 1-5 pts. wt. nano-silver, 15-25 pts. wt. titanium dioxide, 0.5-0.8 pt. wt. antioxidants, 0.2-0.8 pt. wt. modifier and 0.1-0.5 pt. wt. additive. USE - As modified mineral graphene melt blown cloth. ADVANTAGE - The modified mineral graphene melt blown cloth has excellent antibacterial properties, excellent anti-allergic properties, filtration rate and flexibility. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the modified mineral graphene melt blown cloth, comprising adding the polypropylene, toughening agent, high-carbon alkanes, graphene materials, nano-silver, titanium dioxide, antioxidants, modifiers, and additives to the mixing box in sequence for stirring and mixing to obtain raw material mixture, (b) adding the raw material mixture to a screw extruder for melt extrusion to obtain a melt, (c) filtering the melt through a double-piston filter device to obtain a filtered melt, (d) drawing the trickle by the melt through a high-speed hot air stream, mixing room temperature air on both sides into the drafting hot air stream to cool the trickle to obtain ultrafine fibers, and (e) collecting the superfine fibers on the condensation net curtain, using own waste heat to stick to each other, and passing the trimming machine to cut the edges, and winding on the winding roller.
