Abstract
The present invention provides a novel process which imparts anisotropy strength to a rubber article. The process of the present invention includes mixing a rubber composition under a shearing force in a certain direction and then vulcanizing it in a mold, wherein said rubber composition comprises a base rubber, 3 to 100 parts by weight of a metal salt of an alpha, beta-unsaturated fatty acid, and 0.5 to 5.0 parts by weight of an organic peroxide; parts by weight being based on 100 parts by weight of base rubber.
Claims11
A process for preparing a rubber composition having anisotropy strength, comprising mixing said rubber composition under shearing force in a rubber orientation direction and vulcanizing said composition while in a mold, said rubber composition comprising a base rubber, 3 to 100 parts by weight of a metal salt of an alpha, beta-unsaturated fatty acid, and 0.5 to 5.0 parts by weight of an organic peroxide;
- said parts by weight being based on 100 parts by weight of said base rubber wherein crystals of said metal salt are oriented with a direction of rubber molecules in said rubber composition when mechanically mixed.
