NOVELTY - Thermoplastic resin and fiber composite sheet comprises 30-40 pts. wt. polyethylene terephthalate-1,4-cyclohexanedimethanol (PETG) resin, 5-7 pts. wt. random copolymer polypropylene, 12-14 pts. wt. polystyrene microsphere unit plant fiber reinforced materials, adhesion promoter, coupled graphene nanoparticles, polyphenylene sulfide and Polyethylene glycol monoallyl ether oligomer. A base layer of the sheet material is processed with 5-7 parts of stiffening agent, the top and bottom of the base sheet are both bonded with hot-melt film. The hot-melt film is far away Ultra-high molecular weight polyethylene fiber is bonded to one side of the sheet base layer. The preparation method comprises (i) uniformly mixing polyethylene glycol monoallyl ether oligomer and coupled graphene nanoparticles; (ii) combining polyethylene terephthalate-1,4-cyclohexanedimethanol PETG resin, random copolymer polypropylene, plant fiber reinforced materials. USE - Used as thermoplastic resin and fiber composite sheet. DETAILED DESCRIPTION - Thermoplastic resin and fiber composite sheet comprises 30-40 pts. wt. polyethylene terephthalate-1,4-cyclohexanedimethanol (PETG) resin, 5-7 pts. wt. random copolymer polypropylene, 12-14 pts. wt. polystyrene microsphere unit, 8-10 pts. wt. plant fiber reinforced materials, 3-5 pts. wt. adhesion promoter, 16-20 pts. wt. coupled graphene nanoparticles, 2-4 pts. wt. polyphenylene sulfide and 7-9 pts. wt. Polyethylene glycol monoallyl ether oligomer. A base layer of the sheet material is processed with 5-7 parts of stiffening agent, the top and bottom of the base sheet are both bonded with hot-melt film. The hot-melt film is far away Ultra-high molecular weight polyethylene fiber is bonded to one side of the sheet base layer. The preparation method comprises (i) uniformly mixing polyethylene glycol monoallyl ether oligomer and coupled graphene nanoparticles mixed using high-speed mixing equipment to obtain a thickening liquid, which is ready for use; (ii) combining polyethylene terephthalate-1,4-cyclohexanedimethanol PETG resin, random copolymer polypropylene, plant fiber reinforced materials, 2 polyphenylene sulfide and stiffener passed into the high-temperature furnace for high-temperature heating for 4-6 hours. In the process of high-temperature treatment in the high-temperature furnace, a certain amount of adhesion promotion is added every 10 minutes Agent to obtain a liquid mixture; (iii)adding mixture, the thickening liquid and polystyrene microsphere units to the high-speed mixing equipment for high-speed mixing to obtain a colloidal mixture; (iv) passing colloidal mixture into the forming mold for forming operation to obtain a solid sheet base layer; (v) soaking the base layer of the sheet in a solution of vinyl silicone oil for 45-55 minutes, and then using a high-pressure water gun for cleaning; (vi) placing the sheet base layer cleaned in the curing chamber for curing operation to obtain the finished sheet base layer; (vi) binding a layer of hot melt film on the top and bottom of the sheet base layer , and then on the side of the hot melt film (2) away from the sheet base layer, carrying out bonding ultra-high molecular weight polyethylene fiber, and using thermoforming equipment to bond two layers of ultra-high molecular weight polyethylene fiber, where two layers of hot-melt film and a layer of sheet base layer are hot pressed together, and finally mechanical polishing and corona treatment on the side of the ultra-high molecular weight polyethylene fiber away from the sheet base layer to obtain a composite sheet with light weight, high hardness and impact resistance.
