More specifically, the present invention relates to a hydrogenated-tolyl rubber composition capable of providing a cross-linked molded article having excellent gas shielding properties, heat resistance, and wear characteristics.
- the main refrigerant used in refrigerators and the like is Freon R-134a (1,1,1,2-tetrafluoroethane), a new refrigerant, but due to environmental regulations and other issues, it will be used in the future. Is scheduled to be banned, and hydrocarbon-based gas or carbon dioxide gas is attracting attention as a substitute for this refrigerant. Of these, hydrocarbon-based gas has a significantly high risk of explosion and combustion, so it can be said that the world is moving toward using carbon dioxide gas as the next refrigerant.
- carbon dioxide gas has a higher pressure than chlorofluorocarbon and has high permeability and solubility in commonly used polymer materials, so blisters (foaming) are liable to occur, even if pre-stars do not occur.
- the polymer itself permeates carbon dioxide gas, making it difficult to maintain pressure and seal.
- rubber materials also generally have a high carbon dioxide permeability, especially at 1 Mpa or higher, so that the phenomenon is remarkable, so that the carbon dioxide gas cannot be sufficiently sealed.
- carbon dioxide since carbon dioxide is easily dissolved in a polymer, it swells greatly, and as a result, rubber material parts cannot be used in an apparatus using carbon dioxide gas.

- a co-crosslinking agent for example, triallyl (iso) cyanuric , Trimethylolpropane tri (meth) acrylate, triallyl trimellitate, butadiene oligomer, etc. are used in an amount of about 1 to 10 parts by weight, preferably about 1 to 5 parts by weight, per 100 parts by weight of hydrogenated nitrile rubber. .
- processing aids such as stearic acid, palmitic acid and paraffin
- acid acceptors such as zinc oxide, magnesium oxide and hydrotalcite, antioxidants and plasticizers.
- the various compounding agents used are appropriately added and used.
- the composition is prepared by kneading using a kneading machine such as an intermix, kneader, Banbury mixer or an open roll, and the crosslinking is carried out using an injection molding machine, a compression molding machine, a vulcanizing press, or the like. It is generally used by heating at about 160 to 220 ° C. for about 1 to 10 minutes, and if necessary, heat treatment at about 180 ° C. or more for about 1 to 30 hours. Such a heat treatment is also effective for further improving heat resistance.
