Abstract

A composition for vulcanizing adhesion, comprises a rubber (a), at least one compound (b) selected from the group consisting of salts of 1,8-diazabicyclo(5.4.0) undecene-7, salts of 1,5-diazabicyclo(4.3.0)-nonene-5, 1,8-diazabicyclo(5.4.0) undecene-7, and 1,5-diazabicyclo(4.3.0)-nonene-5, and at least one water-carrying substance (c) selected from water-absorbed substances and hydrated substances.

Claims (14)

1. A composition for vulcanizing adhesion, comprising a rubber (a), at least one compound (b) selected from the group consisting of salts of 1,8-diazabicyclo(5.4.0) undecene-7, salts of 1,5-diazabicyclo(4.3.0)-nonene-5,1,8-diazabicyclo(5.4.0) undecene-7, and 1,5-diazabicyclo(4.3.0)-nonene-5, and at least one water-carrying substance (c) selected from a hydrate of a sulfate of a metal selected from the group consisting of calcium, magnesium, sodium, and copper, and/or a hydrate of an acetate of calcium.

2. The composition for vulcanizing adhesion according to claim 1 , wherein the water-carrying substance (c) is a water-absorbed substance in which a polyether compound absorbs water, a water-absorbed substance in which a metal compound absorbs water, and/or a metal salt hydrate.

3. The composition for vulcanizing adhesion according to claim 1 , further comprising an epoxy resin (d).

4. The composition for vulcanizing adhesion according to claim 1 , wherein the rubber (a) is at least one rubber selected from the group consisting of acrylonitrile butadiene rubber (NBR), hydrogenated NBR (H-NBR), acrylic rubber (ACM), ethylene acrylate rubber (AEM), fluorine-contained rubber (FKM), chloroprene rubber (CR), chlorosulfonated polyethylene (CSM), chlorinated polyethylene (CPE), and ethylene propylene rubbers (EPM and EPDM).

5. The composition for vulcanizing adhesion according to claim 1 , wherein the compound (b) is a least one compound selected from the group consisting of a p-toluenesulfonic acid salt of 1,8-diazabicyclo(5.4.0) undecene-7, a phenol salt of 1,8-diazabicyclo(5.4.0) undecene-7, a phenolic resin salt of 1,8-diazabicyclo(5.4.0) undecene-7, an orthophthalic acid salt of 1,8-diazabicyclo(5.4.0) undecene-7, a formic acid salt of 1,8-diazabicyclo(5.4.0) undecene-7, an octylic acid salt of 1,8-diazabicyclo(5.4.0) undecene-7, a p-toluenesulfonic acid salt of 1,5-diazabicyclo(4.3.0)-nonene-5, a phenol salt of 1,5-diazabicyclo(4.3.0)-nonene-5, a phenolic resin salt of 1,5-diazabicyclo(4.3.0)-nonene-5, an orthophthalic acid salt of 1,5-diazabicyclo(4.3.0)-nonene-5, a formic acid salt of 1,5-diazabicyclo(4.3.0)-nonene-5, an octylic acid salt of 1,5-diazabicyclo(4.3.0)-nonene-5, 1,8-diazabicyclo(5.4.0) undecene-7, and 1,5-diazabicyclo(4.3. 0)-nonene-5.

6. The composition for vulcanizing adhesion according to claim 1 , wherein the amount of the compound (b) is from 0.1 to 10 parts by weight for 100 parts by weight of the rubber (a).

7. The composition for vulcanizing adhesion according to claim 1 , further comprising a vulcanizing agent (e), wherein the rubber (a) is epichlorohydrin rubber.

8. The composition for vulcanizing adhesion according to claim 6 , wherein the vulcanizing agent (e) is at least one vulcanizing agent selected from the group consisting of quinoxaline vulcanizing agents, thiourea vulcanizing agents, mercaptotriazine vulcanizing agents, bisphenol vulcanizing agents, sulfur-contained vulcanizing agents, and peroxide vulcanizing agents.

9. The composition for vulcanizing adhesion according to claim 7 , wherein the epichlorohydrin rubber is a polymer having a polymerization unit based on epichlorohydrin, and a polymerization unit based on ethylene oxide.

10. The composition for vulcanizing adhesion according to claim 7 , wherein the epichlorohydrin rubber is a polymer having a polymerization unit based on epichlorohydrin, a polymerization unit based on ethylene oxide, and a polymerization unit based on ally glycidyl ether.

11. The composition for vulcanizing adhesion according to claim 7 , wherein the amount of the compound (b) is from 0.5 to 3.0 parts by weight for 100 parts by weight of the epichlorohydrin rubber.

12. A laminated body, wherein the composition, for vulcanizing adhesion, recited in claim 1 is used.

13. A tube or hose, comprising the laminated body recited in claim 12 .

14. A fuel pipe for an automobile, comprising the tube or hose recited in claim 13 .
