▎ 摘  要

NOVELTY - The silicone patch has a composite silicone layer which is provided with a composite silicone layer having a soft sheet-like or plate-like structure graphene and a PU functional group, and the composite silicone layer is provided with a graphene silicone layer composed of a mixture of graphene and silicone. The upper portion of the graphene silicone layer is composed of a material having a PU functional group, is a material having an isocyanate group and a polyol. An independent interface layer positioned above the graphene silicone layer is formed by the material having a PU functional group. The material having a PU functional group is a polymethacrylic acid resin having a PU functional group, is a polymethacrylic acid resin having an isocyanate group and a polyol. A hot-melt adhesive (HMA), pressure-sensitive adhesive, reactive adhesive, moisture-curing reactive polyurethane adhesive (PUR) is used as the material of the adhesive layer. USE - Graphene silicone patch used in wearing article such as clothes or eye mask. ADVANTAGE - The graphene silicone patch has excellent stability, chemical inactivity and hydrophobicity, and does not cause allergy even if silicone is directly and completely stuck to the skin.
