Abstract

A rubber composition of the present technology comprises: from 0.5 parts by mass to 1.5 parts by mass of sulfur, from 0.2 parts by mass to 0.6 parts by mass of a thiuram vulcanization accelerator, from 0.2 parts by mass to 0.6 parts by mass of a guanidine vulcanization accelerator, from 0.15 parts by mass to 0.8 parts by mass of a sulfenamide vulcanization accelerator, and from 0.1 parts by mass to 1.5 parts by mass of a thiourea vulcanization accelerator per 100 parts by mass of a diene polymer containing a chloroprene rubber.

First claim

What is claimed is:

1. A laminated body of a rubber composition and a metal comprising:
a rubber layer containing the rubber composition, the rubber composition comprising:
from 0.5 parts by mass to 1.5 parts by mass of sulfur,
from 0.2 parts by mass to 0.6 parts by mass of a thiuram vulcanization accelerator,
from 0.2 parts by mass to 0.6 parts by mass of a guanidine vulcanization accelerator,
from 0.15 parts by mass to 0.8 parts by mass of a sulfenamide vulcanization accelerator, and
from 0.1 parts by mass to 1.5 parts by mass of a thiourea vulcanization accelerator,

per 100 parts by mass of a diene polymer containing a chloroprene rubber; and
a reinforcing layer that is provided on the rubber layer and has a metal surface.

2. The laminated body of a rubber composition and a metal according to claim 1 , wherein the metal surface is formed by plating with brass.

3. The laminated body of a rubber composition and a metal according to claim 1 , wherein the reinforcing layer has a braided structure in which wires have been braided, or a spiral structure.

4. A vulcanized rubber product, the rubber layer of the laminated body of a rubber composition and a metal described in claim 1 being vulcanized in the presence of sulfur and adhered to the reinforcing layer.

5. The vulcanized rubber product according to claim 4 , wherein the vulcanized rubber product is a hose.

6. The vulcanized rubber product according to claim 5 , wherein the hose is produced by vulcanizing in an oven vulcanization device.

7. A laminated body of a rubber composition and a metal comprising: a rubber layer containing the rubber composition, the rubber composition comprising:
from 0.5 parts by mass to 1.5 parts by mass of sulfur,
from 0.2 parts by mass to 0.6 parts by mass of a thiuram vulcanization accelerator,
from 0.2 parts by mass to 0.6 parts by mass of a guanidine vulcanization accelerator,
from 0.15 parts by mass to 0.8 parts by mass of a sulfenamide vulcanization accelerator, and
from 0.1 parts by mass to 1.5 parts by mass of a thiourea vulcanization accelerator,

per 100 parts by mass of a diene polymer containing a chloroprene rubber,
wherein, in the diene polymer, a content of the chloroprene rubber is from 40 mass % to 100 mass %, and a content of a styrene butadiene rubber is from 0 mass % to 60 mass %; and a reinforcing layer that is provided on the rubber layer and has a metal surface.

8. The laminated body of a rubber composition and a metal according to claim 7 , wherein the metal surface is formed by plating with brass.

9. The laminated body of a rubber composition and a metal according to claim 8 , wherein the reinforcing layer has a braided structure in which wires have been braided, or a spiral structure.

10. The laminated body of a rubber composition and a metal according to claim 7 , wherein the reinforcing layer has a braided structure in which wires have been braided, or a spiral structure.

11. A vulcanized rubber product, the rubber layer of the laminated body of a rubber composition and a metal described in claim 7 being vulcanized in the presence of sulfur and adhered to the reinforcing layer.

12. The vulcanized rubber product according to claim 11 , wherein the vulcanized rubber product is a hose.

13. The vulcanized rubber product according to claim 11 , wherein the hose is produced by vulcanizing in an oven vulcanization device.

14. A vulcanized rubber product, the rubber layer of the laminated body of a rubber composition and a metal described in claim 2 being vulcanized in the presence of sulfur and adhered to the reinforcing layer.

15. A vulcanized rubber product, the rubber layer of the laminated body of a rubber composition and a metal described in claim 3 being vulcanized in the presence of sulfur and adhered to the reinforcing layer.
