▎ 摘　　要

NOVELTY - An electric heating fabric for thermal insulation and protection comprises fiber heating layer connected to external battery whose lower surface has flame retardant and heat insulation layer and upper surface is made of 1st insulating and thermally conductive layer, graphene oxide layer, and 2nd insulating and thermally conductive layer arranged in this order from bottom to top. Fiber heating layer is made of non-woven fabric as a base layer, and graphene is used as a conductive heating material. Flame retardant and heat insulation polystyrene film, 1st insulating and thermally conductive layer, and 2nd insulating and thermally conductive layer adopt thermally conductive silicone film, and thickness of 1st insulating and thermally conductive layer is 20-50% of thickness of 2nd insulating and thermally conductive layer. USE - An electric heating fabric for thermal insulation and protection. ADVANTAGE - The fiber heating layer is used to form a uniform heating film to achieve arbitrary cutting, which solves the problem of existing heating fabric which is cumbersome to make and cannot be arbitrarily cut. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of electric heating fabric for thermal insulation protection which involves (1) placing flame-retardant thermal insulation layer on substrate, heating fibers, placing layer on surface of flame-retardant and heat-insulating layer and squeezing to form tight bond; (2) spraying thermally conductive silicone liquid to form 1st insulating and thermally conductive film on surface of fiber heating layer, and curing by constant temperature extrusion to form 1st insulating and thermally conductive layer; and (3) spraying graphene oxide resin solution and thermally conductive silica gel liquid on surface of 1st insulating and thermally conductive layer in order according to the method previous step to form graphene oxide layer and 2nd insulating and thermally conductive layer.
