望されている。2. Description of the Related Art Heretofore, it has been generally practiced to lay marble or granite on a floor surface, a wall surface, a ceiling surface or the like to create a room full of luxury. However, natural marble and granite are very expensive and are very hard, so pedestrians are often injured when they fall. Of course, in sports facilities and clubhouses where spiked shoes are used, natural marble and granite are often chipped, and spiked shoes are dangerous because they are slippery. Therefore, alternatives to natural marble and granite are desired.

あり、天然の大理石の様な質量感は得られない。As such a rubber product, a product obtained by kneading a semi-vulcanized or vulcanized rubber chip into an unvulcanized rubber sheet and vulcanizing is known. However, only a monotone speckled pattern is obtained. In addition, semi-vulcanized or vulcanized rubber chips are sprayed in the mold in advance, an unvulcanized rubber sheet of a different color is placed on this, and pressure and vulcanization are performed to change the rubber chip pattern to that of the vulcanized rubber sheet. It is also known to form on the surface. However, since the rubber chip patterns are only randomly arranged in a plane, it does not have the mass feel of natural marble. Further, when the unvulcanized rubber composition is rolled to form an unvulcanized rubber sheet, the unvulcanized rubber pellets are sprayed on the sheet, and the pellets are stretched with a calendar roll or the like to form the unvulcanized rubber sheet. It is also known to form a flow pattern by integration. However, again, since the flow pattern made of stretched rubber chips is only randomly arranged in a plane, it is monotonous and does not give the mass feeling like natural marble.

The unvulcanized rubber composition was mixed, and this mixture was molded to prepare an unvulcanized rubber sheet. At this time, by stopping the mixing before the unvulcanized rubber compositions are evenly mixed with each other, a large number of different color portions different in color from the ground color of the unvulcanized rubber sheet are formed inside the unvulcanized rubber sheet. And, I tried to disperse a lot of rubber chips of different color from the background color.

This monotonous flow pattern is due to the above-mentioned differently colored portion, and the spots of monotonous arrangement are due to the above rubber chips.

In the production method of the present invention, a plurality of types of unvulcanized rubber compositions in which a large number of rubber chips are mixed and having different colors are prepared.

There is no particular limitation. For example, natural rubber, styrene-butadiene rubber, butadiene rubber, acrylonitrile rubber,
There are chlorosulfonated polyethylene, ethylene-propylene rubber and the like, and two or more kinds may be blended. In the unvulcanized rubber composition, pigment, dye, sulfur, vulcanization accelerator,

ートを作製する際に、空孔を生じやすくなる。When manufacturing a rubber chip, a vulcanized rubber plate or the like is manufactured by mixing the above rubber raw materials with the above-mentioned chemicals for rubber. Alternatively, a used vulcanized rubber plate may be used. These vulcanized rubber plates are crushed and granulated to obtain vulcanized or semi-vulcanized rubber chips. The particle size of this rubber chip is preferably in the range of 1 mm-10 mm. If the particle size of the rubber chip is less than 1 mm, it becomes difficult to form a sharp mosaic pattern on the cut surface of the rubber chip. Further, when the particle size of the rubber chips exceeds 10 mm, holes are likely to be formed when the sheet is produced.

加硫が始まり、所望のシートが成形できなくなる。Next, these unvulcanized rubber compositions having different colors are mixed. At this time, it is preferable to mix as follows. That is, each unvulcanized rubber composition is appropriately weighed, and separately heated (heated) so that the temperature of the dough is 60 ° C to 130 ° C. Here, if the heating temperature is lower than 60 ° C., holes are likely to be formed in the obtained sheet. If the heating temperature exceeds 130 ° C., vulcanization of the rubber begins and the desired sheet cannot be formed.

機より取り出す。Next, each of the hot-pressed unvulcanized rubber compositions is kneaded to mix the unvulcanized rubber compositions having different colors. At this time, when the unvulcanized rubber compositions are completely uniformly mixed, a homogeneous unvulcanized rubber composition is obtained, and its color becomes an intermediate color of the primary colors. Therefore, the mixing is stopped before the unvulcanized rubber compositions are completely and uniformly mixed, and the mixture is taken out from the kneader.

Further, a large number of rubber chips 4 are dispersed inside the cloth 2. The differently colored portion 3 has a relatively round shape because it is before rolling.

Very monotonous flow patterns and spots appear on a and b. This monotonous flow pattern is caused by the different color portion 6, and the spots of monotonous arrangement are caused by the rubber chip 4. The different color portion 6 has a flow pattern because it is stretched at the time of molding.
