NOVELTY - Graphene floor heating film comprises graphene heating layer (1), packaging layer and insulating layer . The packaging layer comprises an upper packaging layer (2) and a lower packaging layer (3), which are respectively attached to the upper surface and the lower surface of the graphene heating layer. The insulating layer comprises an upper insulating layer (4) and a lower insulating layer (5), which are correspondingly attached to the outer surfaces of both layer respectively. The graphene heating layer comprises a layered frame body frame and blocky graphene blocks. The frame body frame is composed of an upper frame layer and a lower frame layer, multiple grooves are formed in the opposite inner surfaces of the upper frame layer and the lower frame layer, cavities for accommodating the graphene blocks are formed in grooves after the upper frame layer and the lower frame layer are combined, and multiple graphene blocks are embedded in cavities. USE - Graphene floor heating film with fast heating. ADVANTAGE - The graphene auxiliary layer has good hardness, folding and compression resistance, friction resistance, adhesion, light resistance, chemical resistance and water resistance, and is more reliably combined with the far infrared graphene layer. DETAILED DESCRIPTION - Graphene floor heating film comprises graphene heating layer (1), packaging layer and insulating layer. The packaging layer comprises an upper packaging layer (2) and a lower packaging layer (3), which are respectively attached to the upper surface and the lower surface of the graphene heating layer. The insulating layer comprises an upper insulating layer (4) and a lower insulating layer (5), which are correspondingly attached to the outer surfaces of both layer respectively. The graphene heating layer comprises a layered frame body frame and blocky graphene blocks. The frame body frame is composed of an upper frame layer and a lower frame layer, multiple grooves are formed in the opposite inner surfaces of the upper frame layer and the lower frame layer, cavities for accommodating the graphene blocks are formed in the grooves after the upper frame layer and the lower frame layer are combined, and the multiple graphene blocks are embedded in the cavities one by one. The graphene block comprises a far infrared graphene layer, an auxiliary layer is attached to the upper surface and the lower surface of the far infrared graphene layer. The auxiliary layer comprises 63.5-73.5 wt.% polyvinyl chloride, 3.5-5.5 wt.% thickening agent, 5.5-7.5 wt.% dispersing agent, 1-3 wt.% anti-aging agent, 2.5-4.5 wt.% antioxidant, 11.5-15.5 wt.% film-forming additive, and 2-8 wt.% titanium oxide powder. The thickening agent is a mixture of polyacrylate, methyl cellulose and casein. The dispersing agent is a mixture of microcrystalline paraffin and zinc stearate. The anti-aging agent is free radical trapping agents such as quinones and ultraviolet absorbers. The antioxidant is zinc dialkyl dithiophosphate and zinc dialkyl dithiocarbamate. The film-forming auxiliary agent is flatting agent, a defoaming agent, a dispersing agent and paraffin according to a mass ratio of 2:1.5:1:3. The mass ratio of the polyvinyl chloride and film-forming additive is 4:1-6:1. The mass ratio of polyvinyl chloride and titanium oxide powder is 16:1-28:1.
