NOVELTY - The utility model claims a surface heating seat heating pad, comprising a graphene heating component and a packaging sleeve, the packaging sleeve is formed by sealing the symmetrical upper packaging layer and the lower packaging layer, the upper packaging layer and the lower packaging layer comprise water-repellent oil-repellent non-woven fabric, the first hot melt adhesive film, a polymer film and a second hot melt adhesive film, the first hot melt adhesive film is coated on the water-repellent oil-repellent non-woven fabric, the high molecular film is adhered to the first hot melt adhesive film through the hot-pressing film coating machine, the second hot melt adhesive film is coated on the high molecular film, the upper and lower surfaces of the graphene heating assembly are respectively between the high molecular film of the upper packaging layer and the high molecular film of the lower packaging layer through the second hot melt adhesive film. The utility model adopts the water-repellent and oil-repellent and a packaging layer capable of resisting most acid-base etching in the heating pad, so it effectively improves the waterproof effect of the heating pad and acid-alkali-proof effect and can satisfy standard in the industry.
