Title:
RESIN-VULCANIZED RUBBER COMPOSITION
Document Type and Number:
Japanese Patent JP3700143
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a resin-vulcanized rubber composition which is not corrosive to a metallic part with which it is in contact even where the metallic parts is not coated with a rust preventive and has a high vulcanization rate by adding an alkyl-containing a aromatic sulfonic acid to a composition comprising a natural or synthetic rubber and an alkylphenolic resin.
SOLUTION: 100 pts.wt. natural or synthetic rubber is mixed with 1-25 pts.wt. vulcanizing agent being an alkylphenolic resin obtained by condensing a 1-18C alkyl-containing phenol with formaldehyde, and 0.01-50 pts.wt. vulcanization accelerator being a 2-30C alkyl-containing aromatic sulfonic acid to obtain a resin-vulcanized rubber composition. This composition may contain, if necessary, a filler such as carbon black, calcium carbonate, clay, silica, zinc oxide, magnesium oxide, or titanium white or a softener such as a fatty acid, a paraffinic process oil, an aromatic process oil, or a wax.
