Title:
スチールコード接着用ゴム組成物及びコンベヤベルト
Document Type and Number:
Japanese Patent JP7453501
Kind Code:
B2
Abstract:
To provide a rubber composition for steel cord adhesion excellent in water-resistant adhesiveness, and a conveyor belt.SOLUTION: The rubber composition for steel cord adhesion contains a rubber component containing a diene rubber, an organic acid cobalt salt, sulfur, water, an organic acid having carboxy groups or acid anhydride groups, and a halogen compound. The total amount of carboxy ions of the organic acid cobalt salt, protons from the water, the carboxy groups or the acid anhydride groups of the organic acid, and halogen atoms of the halogen compound is 0.02-0.50 mol based on 100 pts.mass of the rubber component. The content of a vulcanization accelerator is 0.0-1.0 pt.mass based on 100 pts.mass of the rubber component. A conveyor belt 1 is formed of steel cords 2, a cover rubber layer 6, and a coat rubber layer 4 comprising the rubber composition for adhesion.SELECTED DRAWING: Figure 1
