[0076] Mix the ingredients shown in Table 1 and Table 2 except the plasticizer and release agent in a Henschel mixer, and add the plasticizer when the temperature of the mixture rises to 80°C. It is completely dry (it is called the state where the plasticizer is absorbed by the vinyl chloride resin particles and the above mixture becomes loose.), and then when the composition is cooled to below 70°C, add vinyl chloride resin particles as a release agent to prepare a powder Vinyl chloride resin composition for molding. Then, sprinkle the vinyl chloride resin composition for powder molding into a textured mold heated to 250°C, place it for 13 seconds to melt, shake off the remaining composition, and place it in an oven set at 200°C Then, after 60 seconds, the mold was cooled with cooling water, and when the mold temperature was cooled to 40° C., a vinyl chloride resin molded sheet of 205 mm×298 mm×1 mm was released from the mold. The obtained vinyl chloride resin molded sheet w...
