NOVELTY - The utility model claims a double-faced adhesive tape structure without base material, comprising a silica gel composite layer, the inner part of the silica gel composite layer is provided with several sodium bicarbonate particles, the left and right sides of the inner part of the silica gel composite layer are provided with a side seam, the upper and lower surfaces of the silica gel composite layer are provided with a covered crystal layer, one side of the upper and lower covered crystal layer is provided with a graphene coating, the upper and lower graphene coating are provided with a acrylic adhesive layer, the opposite sides of the acrylic adhesive layer on the upper and lower sides are provided with a pressure-sensitive adhesive layer, the graphene coating can well ensure the tensile-resistant amplitude of the non-substrate double-faced adhesive tape, at the same time, the heat of the surface bonding the silica gel composite layer and sodium bicarbonate particles for fast heat transfer, heat transfer to the cladding crystal layer, through the crystal in the crystal layer of the crystal heat-conducting unidirectivity, fast radiating to the two sides of the double-faced adhesive tape without substrate, so as to avoid the heat caused by the pressure-sensitive adhesive layer bonding failure.
