Abstract
Official abstract text for this publication.
Provided are a rubber composition for hoses containing acrylonitrile butadiene rubber, a filler, a resorcin-formaldehyde precondensate, an aldehyde-ammonia vulcanization accelerator, and a fatty acid diester, and a hose including a layer formed using the same.
First claim
Opening claim text (preview).
The invention claimed is: 1. A rubber composition for hoses, comprising: acrylonitrile butadiene rubber, a filler, a resorcin-formaldehyde precondensate, an aldehyde vulcanization accelerator, and a fatty acid diester, wherein the resorcin-formaldehyde precondensate does not contain rubber latex. 2. The rubber composition for hoses according to claim 1 , wherein the total number of carbon atoms making up the fatty acid diester is at least 12. 3. The rubber composition for hoses according to claim 1 , wherein a fatty acid diester content is 5 to 15 parts by mass per 100 parts by mass of the acrylonitrile butadiene rubber. 4. A hose comprising a layer formed using the rubber composition for hoses according to claim 1 . 5. The rubber composition for hoses according to claim 2 , wherein a fatty acid diester content is 5 to 15 parts by mass per 100 parts by mass of the acrylonitrile butadiene rubber. 6. The rubber composition for hoses according to claim 1 , comprising only the aldehyde-ammonia vulcanization accelerator as a vulcanization accelerator. 7. A rubber composition for hoses, comprising: acrylonitrile butadiene rubber, a filler, a resorcin-formaldehyde precondensate, an aldehyde-ammonia vulcanization accelerator, and a fatty acid diester, wherein the rubber composition for hoses does not contain rubber latex. 8. The rubber composition for hoses according to claim 1 , comprising only the acrylonitrile butadiene rubber as a rubber component.
