FIELD: technological processes.SUBSTANCE: invention relates to a sheet body capable of preventing icing and/or sticking of snow. Sheet body includes a solid oil-containing polymer layer and an oil-permeable polymer surface layer, which has higher wear resistance than the oil-containing polymer layer, and is layered on one of the surfaces of the oil-containing polymer layer. Oil included in the oil-containing polymer layer includes a first oil component and a second oil component, wherein the second oil component is a phase-separable oil component, which is phase-separable from the first for sweating from the oil-containing polymer layer when the temperature is reduced to a predetermined value or lower, and surface polymer layer has sufficient oil permeability, so that the low-temperature sweating oil component sweating from the oil-containing polymer layer penetrates to the surface of the surface polymer layer, which is opposite to the side of the oil-containing polymer layer.EFFECT: invention provides creation of a sheet body having an improved function of preventing icing and/or snow sticking.17 cl, 6 dwg, 1 tbl |
