Description
Technical Field
The invention belongs to the field of functional materials, relates to a floor heating material, and particularly relates to a graphene floor heating film capable of rapidly heating.
Background
The graphene has excellent mechanical, electrical and thermal properties, and can convert the excellent properties of the monolithic graphene into the properties of macroscopic materials to a certain extent through specific chemical assembly. The graphene film is a typical graphene macroscopic material, and has good electric conductivity and electric heating performance and high electric-heating conversion efficiency. The composite material has wide application prospect in the fields of pipeline anti-freezing, building heating systems and the like, and is expected to replace the existing floor heating and fireplace products.
At present, the existing graphene floor heating film has high decoration requirements, such as good environmental protection property, thin thickness, strong adhesive force, good high temperature resistance and corrosion resistance and strong friction resistance. Generally, it is difficult to maintain these properties at the same time, because some properties are restricted with each other, such as friction resistance, it is difficult to satisfy high adhesion, and it is impossible to ensure fracture resistance and compression resistance at the same time.
In view of this, it is a subject to be studied to provide a graphene floor heating film with rapid heating.
Disclosure of Invention
In view of the above situation, the present invention aims to solve the problems of the conventional graphene floor heating film, so as to improve the performance and quality of the graphene floor heating film.
In order to achieve the purpose, the invention adopts the following technical scheme: a graphene floor heating film capable of rapidly heating comprises a graphene heating layer, a packaging layer and a heat insulation layer;
the method is characterized in that: the packaging layer comprises an upper packaging layer and a lower packaging layer, and the upper packaging layer and the lower packaging layer are respectively attached to the upper surface and the lower surface of the graphene heating layer; the heat-insulating layer comprises an upper heat-insulating layer and a lower heat-insulating layer, and the upper heat-insulating layer and the lower heat-insulating layer are correspondingly attached to the outer surfaces of the upper packaging layer and the lower packaging 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, a plurality of 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 plurality of 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, and the auxiliary layer comprises the following chemical components in percentage by mass:
63.5% -73.5% of polyvinyl chloride; 3.5 to 5.5 percent of thickening agent; 5.5 to 7.5 percent of dispersant; 1% -3% of age resister; 2.5 to 4.5 percent of antioxidant; 11.5 to 15.5 percent of film-forming additive; 2 to 8 percent of 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 a mixture of free radical trapping agents such as quinones and ultraviolet absorbers; the antioxidant is a mixture of zinc dialkyl dithiophosphate and zinc dialkyl dithiocarbamate; the film-forming auxiliary agent is a mixture of a flatting agent, a defoaming agent, a dispersing agent and paraffin according to a mass ratio of 2:1.5:1: 3;
wherein the mass ratio of the polyvinyl chloride to the film-forming additive is 4: 1-6: 1; the mass ratio of the polyvinyl chloride to the titanium oxide powder is 16: 1-28: 1.
according to a further improvement of the invention, the polyacrylate, the methylcellulose and the casein are mixed in a mass ratio of 1:2: 1.5.
As a further improvement of the invention: the mass ratio of the polyvinyl chloride to the auxiliary agent is 4.5: 5.5.
the invention further improves that the mass ratio of the polyvinyl chloride to the titanium oxide powder is 21: 1.
as a further improvement of the invention, the thickener, dispersant and antioxidant are mixed in a mass ratio of 8:12: 1.
As a further improvement of the invention: also includes a silane coupling agent.
As a further improvement of the invention, the thickener also comprises starch modified bentonite.
The invention further improves that the mass ratio of the anti-aging agent to the antioxidant is 1: 2.
since the relationship between the dilution effect in the dispersant and the viscosity increasing effect in the thickener is a trade-off, if the viscosity of the dispersant and the dilution and solidification properties are adjusted to be strong by component adjustment, the viscosity increasing effect of the thickener is weakened, so that the viscosity of the graphene auxiliary layer is insufficient, and the adhesion of the auxiliary layer is insufficient; if the performance of the thickening agent in the components is adjusted to be strong, the dilution and solidification effects of the viscosity of the dispersing agent are weakened, so that the viscosity of the graphene auxiliary layer is enhanced, and the water resistance and the friction resistance of the graphene auxiliary layer are reduced. Therefore, the mass ratios of the dispersant, the thickener and the titanium oxide powder are always contradictory. In addition, the mass ratio of the dispersing agent, the thickening agent and the titanium oxide powder is controlled within a reasonable range, so that the graphene auxiliary layer can obtain good auxiliary performances such as hardness, folding resistance, compression resistance, friction resistance, adhesion, light resistance, chemical resistance, water resistance and the like.
Compared with the prior art, the invention adopting the technical scheme has the following advantages:
through the design of the invention, the graphene auxiliary layer can obtain good auxiliary performances such as hardness, folding resistance, compression resistance, friction resistance, adhesion, light resistance, chemical resistance, water resistance and the like, and can be more reliably attached to the far infrared graphene layer, and meanwhile, the graphene auxiliary layer plays an auxiliary role in the far infrared graphene layer, so that the far infrared graphene layer plays an optimal role.
