ル系樹脂シート及びフィルムの表面性が悪化する。2. Description of the Related Art A calendering method is generally used as a method for producing a hard vinyl chloride resin sheet and film. However, calendering a vinyl chloride resin composition tends to cause plate-out. Plate-out is a phenomenon in which the content in the vinyl chloride resin composition adheres to the surface of the calender roll to cause fogging on the surface of the roll, and when plate out occurs, the vinyl chloride resin sheet and film. The surface property of is deteriorated.

Although the method is often used, if the addition amount is reduced, problems in performance and productivity are likely to occur, and substitution with other substances tends to increase the compounding cost. It was not possible to say that it was a practical method because it could not obtain the desired effect.

選ばれたものが好ましい。The vinyl chloride resin used in the present invention is mainly composed of polyvinyl chloride and vinyl chloride, and other monomers such as vinyl acetate, ethylene, propylene, alkyl vinyl ether, acrylic ester and methacrylic ester. Examples thereof include copolymers obtained by copolymerization reaction of maleic acid ester, acrylonitrile and the like, polyvinyl chloride or the above copolymers and chlorine-containing polymers such as chlorinated polyethylene or polymer blends of polyvinyl chloride and the copolymer. The degree of polymerization of the vinyl chloride resin is preferably selected from the range of 450 to 1000.

が悪くなる。As the calcium carbonate fine powder used in the present invention, precipitated calcium carbonate having an average particle diameter of 0.1 to 0.5 μm, ground calcium carbonate, and surface-treated activated calcium carbonate can be used. . Particle size is 0.
If it exceeds 5 μm, the smoothness of the surface of the obtained hard vinyl chloride resin sheet and film is impaired. On the other hand, if the particle size is less than 0.1 μm, the plate-out prevention effect becomes poor.

た。The amount of calcium carbonate fine powder added is
Although it is appropriately adjusted depending on the degree of plate-out, it should be used in the range of 0.1 to 1 part by weight with respect to 100 parts by weight of the vinyl chloride resin. If the blending amount is less than 0.1 part by weight, the plate-out prevention effect is insufficient,
On the other hand, if it exceeds 1 part by weight, the color tone and surface property of the sheet or film are adversely affected. Generally, calcium carbonate fine powder is used as a filler for vinyl chloride moldings.
It is used in a high composition of more than 1 part by weight, and has not been used until now in the range of 0.1 to 1 part by weight in order to prevent plate-out as in the present invention.
