Claims (6)

In preparing the upper material material, 5 to 100 parts of binder resin having a melting temperature range of 50 to 220 ° C is added to 100 parts of chip raw material mixed with colored hard chips having high hardness and melt fluidity and colored and transparent soft chips. The raw material mixture was laminated on a machine or belt with a thickness of 2 to 8 mm, heated in a gelling oven at 130 to 220 ° C. for 3 to 15 minutes, and then rolled on a rolling roll heated at a surface temperature of 80 to 210 ° C. Method for producing a material having a natural granite pattern characterized in that. The method of claim 1, wherein the colored and transparent soft chip is added by adding 50-150 parts of a plasticizer, if necessary, while heating and stirring a PVC resin having a degree of polymerization of 500-1800 in a mixer rotating at a rate of 50-1600 r.pm. It is made by granulating to 4.0mm size. The colored and transparent soft chip according to claim 2, wherein the PVC paste prepared by adding 40-150 parts of a plasticizer to a paste prepared by heating and stirring the PVC resin and the plasticizer into a paste PVC resin having a degree of polymerization of 500-1800. And adding 500 parts so as to make the particles uniform. The colored and transparent soft chip is manufactured by adding 5-500 parts of a synthetic resin such as ACRYL, EVA or PU having a melting temperature range of 50-220 ° C. to an indenter obtained by heating and stirring a PVC resin and a plasticizer. Characterized by the above. The binder resin is an ACRYL, EVA, PU resin having a melting temperature range of 50-250 ° C with a PVC compound or PVC paste prepared by adding 20-200 parts of a plasticizer to 100 parts of PVC having a degree of polymerization of 500-1800. Prepared by mixing the same. A raw material mixture consisting of a base material such as asbestos paper, mineral paper or glass fiber or a belt such as silicone or teflon, and a chip material and a binder resin mixed with colored hard chips and colored and transparent soft chips having a large difference in hardness and melt flow. A material having a natural granite pattern, wherein the layers are laminated at a thickness of 2-8 mm. ※ Note: The disclosure is based on the initial application.
