可塑性材料の塑性加工方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a method for plastic processing of a plastic material containing a synthetic resin film or sheet.
（ロ）従来の技術及び発明が解決しようとする問題点
従来より、金属箔や金属板等の可塑性材料に、絞りや帳

よって行っている。これは、可塑性材料の展延性を利用
した加工法である。(b) Problems to be solved by conventional techniques and inventions Traditionally, when plastic materials such as metal foils and metal plates are subjected to plastic processing such as drawing or drawing, only pressure is applied without heating. Is going. This is a processing method that takes advantage of the malleability of plastic materials.
一方、合成樹脂製フィルム若しくはシートも可塑性材料
であるが、これは比較的低温で溶融又は軟化するため、
熱を利用して所定の形に加工している。On the other hand, synthetic resin films or sheets are also plastic materials, but because they melt or soften at relatively low temperatures,
Heat is used to process it into the desired shape.

下で加圧のみの塑性加工による方法を採用するのが得策
である。By the way, when trying to give a predetermined shape to a composite material made by adhering a metal foil or the like to a synthetic resin film or the like, it is conceivable to adopt the above-mentioned plastic working method or heat processing method. The processing method using heat requires the following points: - Since metal foil, etc. does not soften at the temperature at which synthetic resin films, etc. soften, metal foils, etc. must be subjected to plastic processing in any case, - - Synthetic resin films, etc. When softening the composite material, there is a risk that the adhesive used to attach the metal foil, etc. and the synthetic resin film, etc. will melt, and that if too much heat is applied, the synthetic resin film, etc. will melt, causing the composite material to melt. There are disadvantages such as damage to the Therefore, in order to give a predetermined shape to a composite material of metal foil, etc. and synthetic resin film, etc., since synthetic resin films, etc. are also plastic, it is necessary to It is advisable to use a plastic working method that involves only applying pressure under heat.

起するに到る。However, synthetic resin films are made up of polymer chains at the molecular level, so if pressure is applied without heating, the polymer chains will become oriented and crystallization will occur or be promoted, resulting in whitening of the area. That happened. For example, when a composite material is subjected to drawing or drawing processing, the synthetic resin film becomes white at some of the corners between the side walls of the central recess and the flange, and at some corners between the side walls of the central recess and the bottom of the central recess. That happened. This is because a particularly large stress is applied to the corner portion, which promotes the orientation of the polymer chains. When such whitening occurs, it leads to the disadvantage that the commercial value of the processed product decreases.
そこで本発明は、合成樹脂製フィルム等にある特定の材

な色になっている。As a result, the transparent surface layer becomes white in a portion of the corner between the side wall of the cylinder and the flange and a portion of the corner between the side wall and the bottom of the cylinder, and remains transparent in other portions. However, there is a layer in which titanium oxide is kneaded as an intermediate layer,
This layer is white in both the corners and other parts as well. Therefore, the appearance of this processed product is white in all parts and has a uniform color.

いる。As a comparative example, a three-layer structure obtained by removing the intermediate layer from the four-layer plastic material described above was subjected to cylindrical drawing under the same conditions as above. As a result, some of the corners of the transparent surface layer turned white, so that the processed product had an appearance in which some of the corners were white and the other parts had the color of aluminum.

。(E) Effects of the Invention As described above, in the present invention, a plastic material containing a synthetic resin film or sheet kneaded with a white pigment is subjected to plastic processing by pressurization without heating. Therefore,
Even if the polymer chains in a synthetic resin film or sheet become oriented and the film or sheet turns white, the color of the synthetic resin film or sheet changes as a whole because it is originally colored white by a white pigment. I don't do anything.
即ち、白色顔料を混練した合成樹脂製フィルム又はシー
