Background
At present, the hole sealing mode of the surface of the PET foam board is to adopt a high-temperature roller to rapidly soften or melt a layer of the surface of the foam board at high temperature in a short time, and then a cold plate is replaced to apply certain pressure to the surface of the PET foam board so as to shrink or combine holes on the surface of the PET foam board, thereby achieving the effect of hole sealing on the surface of the PET foam board; however, the surface of the foam board needs to be softened quickly, so the temperature of the high-temperature roller generally needs to be positioned at a very high degree, and thus the high-temperature roller is always in a high-temperature operation environment of over 400 to 500 ℃, so that the high-temperature roller can be thermally deformed after being heated for a long time and cannot continuously operate for a long time, and in addition, in order to prevent the foam board from being adhered to the high-temperature roller, nano paint or Teflon cloth and the like are arranged on the high-temperature roller, but the high-temperature resistance of the materials is poor, the materials are easy to peel and fall off in the high-temperature operation environment of over 400 to 500 ℃, so the materials arranged on the surface of the high-temperature roller and the surface of the high-temperature roller need to reach a certain high-temperature resistance, a high requirement is provided for the high-temperature resistance of the materials, the production cost of enterprises is increased, and the requirement for high temperature in the manufacturing process is reduced.
