▎ 摘　　要

NOVELTY - Graphene far-infrared floor heating floor comprises a wear-resistant paper layer, a wood grain paper layer and a functional substrate layer. The wear-resistant paper layer is a complex of high-temperature heat transmitted through the functional substrate layer and thermal curing of the colored wood-grain paper layer. The wood-grain paper layer is bonded to the high-temperature functional substrate layer with thermal adhesion. The functional substrate layer comprises PVC resin, calcium carbonate, graphene, tourmaline, graphite, aluminum nitride, calcium zinc stabilizer, stearic acid, impact modifier, Chlorinated Polyethylene (CPE) toughener and poly ethylene (PE) wax. USE - Used as graphene far-infrared floor heating floor. ADVANTAGE - The floor maintains the original wooden floor's anti-moisture, deformation, mildew, and formaldehyde release problems, and improves the floor strength, temperature stability, heat resistance, antistatic property, and far-infrared health. The original thermal conductivity has been increased from 0.6-2.6 W/mk, and the thermal conductivity has increased by more than 3 times; provides the floor heating industry with healthy, is environmentally friendly and economical; has high-efficiency and low-energy-consumption floor heating, filling the gap in the market, and very high usability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the graphene far-infrared floor heating floor comprising (i) adding 30-50 pts. wt. PVC resin, 40-60 pts. wt. calcium carbonate, 0.1-0.5 pts. wt. graphene, 5-10 pts. wt. tourmaline, 10-20 pts. wt. graphite, 5-10 pts. wt. aluminum nitride, 3-10 pts. wt. calcium zinc stabilizer, 0.5-1 pts. wt. stearic acid, 2-5 pts. wt. impact modifier, 2-5 pts. wt. CPE toughener, 0.5-1 pts. wt. PE wax into a high-speed mixer, and heat mixing at 125 degrees C for 1-3 hours, (ii) sending the mixture of step (i) to a cooling mixer with a cooling temperature of 50-60 degrees C for further cooling and mixing for 1-2 hours, (iii) adding mixture material into a twin-screw extruder, heating and extruding into the sheet die to extrude the sheet, (iv) sheet enters the next four-roll calender, and the base material sheet and the wood-grain paper layer and the wear-resistant paper layer are heated and pressed together to fix the thickness at the temperature of the roller of the calender at 165-185 degrees C, enter the cooling conveyor belt, and (v) sheet material enters the cooling conveyor belt to be cooled and cut into a specified specification sheet, and then cutting, grooving, and packaging according to the floor specification DESCRIPTION OF DRAWING(S) - The drawing shows a schematic structural diagram of the graphene far-infrared floor heating floor structure diagram.
