Abstract

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.

Claims (9)

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.
