Abstract
The utility model discloses an EVA waterproof coiled material which comprises a winding drum and a coiled material main body wound on the winding drum, the coiled material main body comprises an EVA main body, a silica gel sheet is attached to the upper surface of the EVA main body, a PET heat-insulating film is attached to the upper surface of the silica gel sheet, a carbon fiber film is attached to the upper surface of the PET heat-insulating film, a bonding layer is arranged on the lower surface of the EVA main body, and the bonding layer is arranged on the lower surface of the EVA main body. A release film layer is arranged on the surface of the bonding layer; by designing the silica gel sheet, the PET heat insulation film and the carbon fiber film, ultraviolet rays and heat can be effectively blocked through the carbon fiber film during use, the coiled material has excellent wear resistance and corrosion resistance, the performance of the coiled material is enhanced through the high temperature resistance and grease erosion resistance of the silica gel sheet, the heat insulation effect can be enhanced through the PET heat insulation film, and the service life of the coiled material is prolonged. When the EVA coiled material is used, the influence of ultraviolet rays, high temperature and grease erosion is reduced, so that the service life is prolonged.
