METHOD FOR COATING FAR-INFRARED RADIATION RESIN SHEET

摘要

The present invention relates to a method for treating a sheet for resin products with functional coating. The method comprises the steps of: (a) producing an intermediate product by mixing a styrene- butadiene copolymer with a far-infrared ray material based on a ceramic material; (b) producing a master batch by mixing the intermediate product with a composition consisting of a compatibilizer, a dispersant, a lubricant, and a resin stabilizer; (c) extruding the master batch in a state of an upper layer film and, at the same time, extruding a resin base material in a state of a lower layer sheet; and (d) producing a resin sheet by laminating and attaching the upper layer film and the lower layer sheet which come in close contact with each other, and cooling and drying the upper layer film and the lower layer sheet. Therefore, productivity of mass production during a process of applying the method to various cases of products can be increased. Meanwhile, degradation of an far-infrared ray element is little, and consequently a radiation rate can be maintained to be constant for a long period of time.
