本発明は、凹凸の大きいエンボス模様付き熱可塑性樹脂
シートの製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for producing a thermoplastic resin sheet with an embossed pattern having large irregularities.

いるが、この方法は連続的に生産できない欠点がある。The conventional method for manufacturing thermoplastic resin sheets with embossed patterns with large irregularities involves heating the thermoplastic resin sheet (hereinafter referred to as 7-T) once cooled and solidified to form a mold that fits the shape of the desired product. A method of molding by contacting with
Methods such as vacuum forming, pressure forming, and press forming have been used, but these methods have the disadvantage that continuous production is not possible.

、これはシート厚みに対して通常１倍以下であり、比較
的大きなエンボスであっても２倍未満でしかない。Additionally, in general, there is no known method to transfer a relatively shallow pattern compared to the sheet thickness, with a depth of 0.3rrVfn or less, onto the sheet surface using an embossing roll at a temperature several tens of degrees higher than the Vicat softening point of the resin during the sheet production process. However, this is usually less than one time the sheet thickness, and even for relatively large embossing, it is less than twice the sheet thickness.
即ち、シート厚みに対して２倍以上の凹凸の大きさにな
ると、従来の方法では光分なエンボス模様が得られない
のが実情である。That is, the reality is that when the size of the unevenness is more than twice the sheet thickness, it is not possible to obtain a bright embossed pattern using conventional methods.
本発明の目的は、シート厚みの２〜１０倍の凹凸をもっ
たエンボス模様付きの熱可塑性樹脂シートを製造する方
法を提供することにある。An object of the present invention is to provide a method for manufacturing a thermoplastic resin sheet with an embossed pattern having irregularities 2 to 10 times the thickness of the sheet.
本発明者等は、上記方法を改良して、シート厚０２倍以

ることができることを見出し、本発明を完成した。The inventors of the present invention improved the above-mentioned method, and as a result of intensive study to manufacture a sheet with unevenness larger than 0.2 times the sheet thickness, the inventors maintained the temperature of the resin entering the embossing roll within a specific temperature range. It was discovered that stable and continuous embossing can be achieved by this method, and the present invention was completed.

徴とする凹凸の大きいエンボス模様付き熱可塑性樹脂シ
ートの製造方法である。なお、ビカット軟化点はＡＳＴ
Ｍ Ｄ−１５２５の規定により測定したものである。That is, in the present invention, when manufacturing a thermoplastic resin sheet having an embossed pattern in which the difference in unevenness is 2 to 10 times the thickness of the sheet, the temperature of the resin is adjusted to 20° with respect to the Vicat softening point of the resin.
This is a method for producing a thermoplastic resin sheet with an embossed pattern having large irregularities, which is characterized by forming an embossed pattern by passing the sheet between embossing rolls at a temperature ranging from a high temperature to a 50° C. low temperature. In addition, the Vicat softening point is AST
It was measured according to the regulations of MD-1525.
本発明に於ては、エンボスをかける温度は、その樹脂の

成形した場合、一旦成形されかげたエンボス模様が充分
成形されず一定の形状のエンボス模様が保てず、目的の
製品が得られない。In the present invention, the embossing temperature is in the range of 10°C to -50°C relative to the Vicat softening point of the resin. If the sheet of the present invention is molded at a temperature higher than this temperature range, the embossed pattern that has been once molded will not be sufficiently molded, and the embossed pattern of a constant shape will not be maintained, making it impossible to obtain the desired product.
一方、この温度範囲より低い温度では、成形困難で目的

本発明に於ける凹凸の大きさは、シート厚みの２〜１０
倍であり、２倍未満では、うまくエンボス模様がつかず
、１０倍を超えるとエンボス模様の保持が困難である。The thermoplastic resin used in the present invention includes polypropylene, polyethylene, polyvinyl chloride, and other thermoplastic resins, and is not particularly limited. In addition, the size of the unevenness in the present invention is 2 to 10 degrees of the sheet thickness, even if these resins are used alone, or a mixture of two or more, or a material blended with inorganic fillers, etc., there is no problem.
If it is less than 2 times, the embossed pattern cannot be formed well, and if it is more than 10 times, it is difficult to maintain the embossed pattern.

が適当である。In the present invention, the sheet before being embossed may be manufactured by any method, and known methods such as extrusion and calendering can be used. The thickness of the sheet varies depending on the purpose, but is usually about 0.2 to 2.5 mm thick.
