NOVELTY - Manufacturing an electric mat comprises: (i) sequentially adding 5-30 wt.% aqueous dispersion in which polytetrafluoroethylene is dispersed in water, 1-5 wt.% polytetrafluoroethylene, 1-10 wt.% polytetrafluoroethylene molding powder, 10-50 wt.% acrylic resin, 0.3-4 wt.% additives, 1-10 wt.% pigment and balance of solvent into a stirring tank and then stirring at 50-100 revolutions/minute for 1-2 hours at 30-40° C to obtain anti-fouling hydrophilic fluororesin, (ii) adding 20-50 wt.% antifouling hydrophilic fluororesin, 10-20 wt.% acrylic resin, 10-20 wt.% modified latex resin, 5-20 wt.% hybrid rubber, 1-10 wt.% polyflon polytetrafluoroethylene-M, 1-5 wt.% ammonium phosphate monobasic, 0.1-2 wt.% lauryl betaine, 0.1-1 wt.% diethylenetriamine and remaining water dispersion-polyurethane resin into a mixing tank, stirring, further adding liquefied graphene solution and stirring to obtain a graphene base resin; (iii) impregnating the graphene base resin and the polyester-based fabric. USE - Used as graphene hot/cold heating electric mat. ADVANTAGE - The electric mat: ensures that there is no heating wire in direct contact with the human body, hence it is safer as a risk of electromagnetic waves, and the thickness of the heating wire can take a comfortable rest because there is no exhaustion in the contact area of the electric mat due to the heat; increases the lifespan of the temperature controller using a short length heating wire; and reduces the amount of power. DETAILED DESCRIPTION - Manufacturing an electric mat comprises: (i) sequentially adding 5-30 wt.% aqueous dispersion in which polytetrafluoroethylene is dispersed in water, 1-5 wt.% polytetrafluoroethylene, 1-10 wt.% polytetrafluoroethylene molding powder, 10-50 wt.% acrylic resin, 0.3-4 wt.% additives, 1-10 wt.% pigment and balance of solvent into a stirring tank and then stirring at 50-100 revolutions/minute for 1-2 hours at 30-40° C to obtain anti-fouling hydrophilic fluororesin, (ii) adding 20-50 wt.% antifouling hydrophilic fluororesin, 10-20 wt.% acrylic resin, 10-20 wt.% modified latex resin, 5-20 wt.% hybrid rubber, 1-10 wt.% polyflon polytetrafluoroethylene-M, 1-5 wt.% ammonium phosphate monobasic, 0.1-2 wt.% lauryl betaine, 0.1-1 wt.% diethylenetriamine and remaining water dispersion-polyurethane resin into a mixing tank, stirring at a rate of 150 revolutions/minute for 10 minutes, further adding 5-20 wt.% liquefied graphene solution and stirring at a rate of 150 revolutions/minute for 30 minutes to obtain a graphene base resin; (iii) impregnating the graphene base resin and the polyester-based fabric, where the amount of the graphene base resin can be reduced by inputting a specific pattern, the area to be used will be 10-60%, and the thickness of the graphene base resin is 20-150 μ m, the creation of the pattern must be divided into an inlet and an outlet, and the total length of one pattern must be 2-20 m and 2-50 patterns between 5-20 m can be used for one electric mat, and the pattern used is to connect each inlet to the inlet heating wire and each outlet to the outlet heating wire; and (iv) using a 3-18m heating wire when manufacturing an electric mat i.e. queen size (2000x 1500), and the used heating wire must be divided into an inlet heating wire and an outlet heating wire to insert into the mat, if heating wires are inserted inside the reinforcing seam line, which is the end (edge) of the electric mat, then the total length of the heating wire is at least 4 m at both ends of the horizontal part, separating the inlet heating line and the outlet heating line, and all parts of the inside except for the edge of the electric mat have a structure in which the heat of the heating wire is transmitted by the graphene pattern of the graphene fabric.
