Description of the Related Art Heretofore, according to Japanese Utility Model Publication No. 34-18648, several kinds of pelletized rubber materials having an appropriate color are mixed in an amorphous form, and heated and pressed to cross-link and mold a shoe-shaped sole. A molding method has been proposed. However, because different color rubber pellets must be prepared, the molding process is complicated and the cost is high, and because the different color rubber pellets flow and fuse with each other at the time of heating and pressing, the boundaries are unclear and the colors are blurred. There was a drawback that you could only get the soles.

−等によって均一に混合されシ−テングされる。In the present invention, the colored rubber-like plastic material is compounded to have a higher softening point than that of the transparent rubber-like plastic material by 10 ° C. or more, preferably 20 ° C. or more. When the temperature difference is less than that, when kneading and sheeting, the colored rubber-like plastic is fused into the crosslinkable transparent rubber-like plastic due to self-heating, and the transparency of the transparent rubber-like plastic is transparent. And the depth of the marble pattern is lost.
When the colored rubber-like plastics are mainly composed of rubber-based plastics, the temperature difference is reduced by reducing the amount of the plasticizer or the softener in the compound as compared with the above-mentioned cross-linkable transparent rubber-like plastics. However, when it is composed of a colorant and other commonly used chemical additives for rubber, and is composed of an elastic plastic compound of a soft compound, the transparency mainly composed of PVC, EVA, PE and 1.2 polybutadiene described above. Compared to the elastic plastics of
In the case of PVC and EVA having a higher degree of polymerization, EVA and PE having a lower vinyl acetate content, and in the case of 1.2 polybutadiene, a PE having a higher crystallinity,
1.2 Polybutadiene as a main component, to which a colorant and, if necessary, a crosslinking agent are added. The crosslinkable transparent rubber-like plastics and the colored rubber-like plastics thus prepared were separately processed by a Banbury mixer, a Henschel mixer, a mixin roll, a kneader, etc. Uniformly mixed and sheeted.

It is mixed at a temperature below the softening point of the rubber-like plastic colored by, etc., and the dough is taken out, sheeted and cut into a shoe sole shape, and the cut shoe sole molding material is heated in a shoe sole mold. It is crosslinked under pressure. When heating and pressing the multi-layered shoe sole molding material in the molding die, a burr groove is provided in the molding die to give direction to the flow of the shoe sole material in the molding die to form a marble pattern. It is also possible to have a streamlined direction in a certain direction. In the present invention, 1 to 30 parts by weight of the colored rubber-like plastic is added to 100 parts by weight of the crosslinkable transparent rubber-like plastic because the addition amount of the colored rubber-like plastic is less than that. If the amount added is too small, a marble pattern cannot be expressed, and if the amount added is more than that, there are too few transparent parts in the molded product, the pattern becomes too flat and the depth is lost. Because there is.

るのでコスト安である。As described above, the crosslinkable transparent rubber-like plastics sheeted and the sheeted and colored rubbery plastics are softened by the crosslinkable colored rubbery plastics. Since the dough is mixed and kneaded at a temperature below the point,
At the time of kneading sheeting, the colored rubber-like plastic material is kneaded and dispersed without mutual compatibility with the crosslinkable transparent rubber-like plastic material, and at the time of sheeting, the rolling direction is maintained while maintaining the aggregated state. To form a marble pattern. Since the shoe sole molding material is laminated in multiple layers in the mold and heated and pressed, the marble pattern in the shoe sole molding material is irregularly scattered in multiple layers in the crosslinkable transparent rubber-like plastic. Since it is formed, it can be seen through the surface of the shoe sole as a three-dimensionally deep marble-like pattern as seen through the surface of the shoe sole. The shoe sole material thus formed is cross-linked by heating, and the colored rubber-like plastic is fixed in a transparent rubber-like plastic as a marble pattern to enhance its mechanical strength and durability. It becomes a sole material with excellent properties. Also, there is no need to pelletize the colored rubber-like plastic,
Sheeting is performed, and a transparent rubber-like plastic material and a colored rubber-like plastic material are kneaded, and only the dough is formed into a sheet shape, so that the cost is low.
