Problems solved by technology

[0003] However, due to the strong van der Waals force between the graphene layers, the dispersion of graphene in common organic solvents is poor, which in turn affects the compatibility and dispersion of graphene in the composite substrate and affects the performance of the glue.

Abstract

The invention discloses a graphene-coated conductive heat storage fabric and a preparation process thereof. Graphene coating glue comprises, by weight, 70-80 parts of an aqueous aliphatic polyurethaneemulsion, 20-30 parts of an aqueous graphene emulsion, 5-10 parts of a cross-linking agent, 5-10 parts of water and 1-3 parts of an acrylate polymer, wherein the solid content of the aqueous aliphatic polyurethane emulsion is 50%, and the graphene content is 30-50%. The functionality of the fabric is improved through coating post-finishing, functions of high conductivity and heat storage are added on the basis of original common coated fabrics, and the fabric can be applied to outdoor fields to cope with harsh outdoor sports climate such as lightning and extreme cold. At the same time, a far-infrared heat storage property of graphene can resist the cold winter, and a graphene material can absorb the radiant heat released by the human body and perform corresponding conversion to release heat by utilizing a far-infrared continuous circulation function of the graphene material.

Description

technical field [0001] The invention belongs to the field of textile fabrics, and in particular relates to a graphene-coated conductive thermal storage fabric and a preparation process thereof. Background technique [0002] If the fabric prepared by the prior art is not finished with graphene coating, the fabric itself does not have conductivity and heat storage. The special graphene coating technology in this solution inherits the consistent heat storage, conductivity, anti-mite, anti-static, anti-radiation, anti-ultraviolet and far-infrared functions of graphene, and the glue made of graphene is bonded to the textile fabric. The fabric prepared after the functional coating has strong electrical conductivity and heat storage function. [0003] However, due to the strong van der Waals force between graphene layers, the dispersion of graphene in common organic solvents is poor, which in turn affects the compatibility and dispersion of graphene in composite substrates and aff...
