▎ 摘  要

NOVELTY - Tent cloth comprises graphene film, Oxford cloth, and PVC film, where the graphene film is the surface layer, the Oxford cloth is the middle layer, and the PVC film is the bottom layer, and are compounded by polyurethane glue, and the PVC film comprises 90-110 pts. wt. PVC, 45-55 pts. wt. plasticizer, 2.5-3.5 pts. wt. barium-zinc stabilizer, 5-10 pts. wt. cold-resistant agent, 20-40 pts. wt. calcium carbonate, 2-3 pts. wt. processing aids, 1-2 pts. wt. flame retardants, 0.5-1.5 pts. wt. antioxidants, and 3-5 pts. wt. pigments. USE - As tent cloth. ADVANTAGE - The tent cloth optimizes the formula of PVC film, increases cold-resistant effect, improves physical and chemical properties, has excellent heat preserving effect, improves the physical property index, improves the stretch resistance of the cloth, and prolongs the shelf-life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the tent cloth, comprising (a) taking PVC film to prepare raw materials, high-stirring in the calender, where the temperature of the calender is 90 degrees C, mixing for 120-140 second, and directly on the filter, extruding, the extrusion temperature is 140-150 degrees C, after extrusion, mixing on the main engine wheel, adjusting the calendering to adjust the thickness to 0.25-0.30 mm, and winding up into a semi-finished product after cooling, (b) using the sizing layer of Oxford cloth, polyurethane glue, and controlling the sizing amount at 50-60 g, and (c) mixing the graphene film and the PVC film on the upper and lower sides of the Oxford cloth and pressed together to form the product.
