本発明は、床面等に敷設される石目調ゴム床材の製造方

するため、ゴム粒子の混入量を増やすことは容易に考え

加すれば製品コストが大幅に上昇する。又、ゴム粒子の
混入量を増量し過ぎると、加硫接着力が低下するので、
出来た製品は強度が弱く来月に供しないものとなる。Generally, colored vulcanized or semi-vulcanized rubber particles are mixed into an unvulcanized rubber composition, the unvulcanized rubber composition is then rolled into a sheet, and the sheet is then vulcanized to form a surface. Methods for producing floor coverings with colored particles are known. However, in this method, the vulcanized or semi-vulcanized rubber particles tend to get inside the vulcanized rubber note during vulcanization and rolling, and very few colored rubber particles appear on the surface. This does not achieve the original purpose of adding colored rubber particles to create a stone-like texture.In order to solve this problem, it is easy to think of increasing the amount of rubber particles mixed in, but the price of rubber particles is , which is about twice as expensive as the rubber binder, so increasing the mixing ratio of rubber particles will significantly increase the product cost. Also, if the amount of rubber particles mixed in is increased too much, the vulcanization adhesive strength will decrease.
The resulting product is weak and cannot be used next month.
そこで従来では一旦加饋の後、表面に削るか又は加硫シ

現出させていた（特開昭６４９０７４５号公報参照）。Conventionally, after heating, the surface was scraped or the vulcanized sheet was divided into layers to expose many of the colored rubber particles on the surface (see JP-A-6490745).
しかしこれらの方法では削り取ったゴム成分が無駄とな
るか又は層分割のための余分な工程を必要とした。However, these methods either waste the scraped rubber component or require an extra step for layer division.

Generally, it is preferable to use colored vulcanized rubber particles made of the same material and the same formulation as the unvulcanized rubber. However, vulcanized or semi-vulcanized rubber particles made of a material different from unvulcanized rubber can also be used. In general, it is preferable to use vulcanized rubber or semi-vulcanized rubber of the same material and composition as the unvulcanized rubber composition from the viewpoint of compatibility.

For every 0 parts, use 2 to 80 parts of colored particles. If the amount of colored particles is less than 2 parts per 100 parts of unvulcanized rubber, the particles will appear unevenly distributed. Moreover, if it is more than 80 parts, the particles will adhere too closely and the cost will be high.
