Definitions
- the present invention relates to an oil hose having improved copper ion resistance, heat resistance, and oil leakage when used at low temperatures.
- NBR Acrylonitrile-butadiene copolymer rubber
- An object of the present invention is to provide an oil hose having excellent heat resistance and oil leakage resistance when used at a low temperature, and further having good copper ion resistance.
- the inner layer is a vulcanized hydrogenated nitrile rubber compound
- the intermediate layer is a vulcanized conjugated gen-based rubber compound
- the outer layer is An oil-based hose is provided, each of which is constituted by a vulcanized ozone-resistant rubber compound.
- the inner layer is composed of unsaturated nitrile, conjugated diene and ethylene copolymerizable therewith. It consists of a hydrogenated nitrile rubber vulcanized compound with an iodine value of 120 or less, obtained by hydrogenating the conjugated part of a copolymer rubber composed of unsaturated unsaturated monomers, and the outer layer is an ozone-resistant rubber vulcanized compound.
- An oil hose is provided which is characterized by comprising o
- the first oil hose of the present invention has a three-layer structure including an inner layer in contact with oil, an intermediate layer formed thereon, and an outer layer formed thereon in contact with outside air.
- the inner layer is formed from a vulcanizate of a hydrogenated nitrile rubber compound.
- the hydrogenated nitrile rubber is composed of a rubber obtained by hydrogenating the conjugated part of an unsaturated nitrile-conjugated diene copolymer rubber, and unsaturated nitrile, conjugated diene, and an ethylenically unsaturated monomer copolymerizable with these. At least one selected from rubbers obtained by hydrogenating the conjugated part of the copolymer rubber is used, and these preferably have a viscosity of 5 to 200.
- the copolymer rubber contains 5 to 60% by weight of an unsaturated nitrile-based monomer unit, 15 to 95% by weight of a conjugated diene-based monomer unit and 0 to 95% by weight of an ethylenically unsaturated monomer unit copolymerizable therewith.
- % Hydrogenated nitrile rubber is obtained by hydrogenating this conjugated gen unit. From the heat resistance and copper ion resistance required for the hose of the present invention (the copper ion elutes into the oil from the copper pipe to which the hose is connected), the degree of hydrogenation was measured according to the JIS method.
- the iodine value is 120 or less, preferably 1 to 80, and more preferably 1 to 50.
- the amount of the unsaturated nitrile monomer unit is appropriately determined within the above range according to the purpose of use (the type of oil).
- the conjugated diene monomer constituting the copolymer rubber include butadiene, 2,3-dimethylbutadiene, isoprene, and 1,3-pentane. Of these, butadiene is preferred.
- unsaturated nitrile monomers Agrillonitrile, methacrylonitrile and the like. Of these, acrylonitrile is preferred.
