6. the rubber combination of above-mentioned 5 records is styrene butadiene rubbers or natural rubber more than the 50 quality % of rubber.
The working of an invention mode
Below, describe the present invention in detail.
At first, describe for rubber processing oil of the present invention.
The viscosity-gravity constant that rubber processing oil of the present invention contains (a) 25～100 quality % (preferred 25～90 quality %) be 0.79～0.87 mineral oil be the underpressure distillation residual oil and (b) the polycyclc aromatic compound amount of 0～75 quality % (preferred 10～75 quality %) less than 3 quality %, the mineral oil of flash-point more than 200 ℃.The viscosity-gravity constant that perhaps contains (a) 25～100 quality % (preferred 25～90 quality %) be 0.790～0.875 mineral oil be the underpressure distillation residual oil and (b) the polycyclc aromatic compound amount of 0～75 quality % (preferred 10～75 quality %) less than 3 quality %, the mineral oil of flash-point more than 200 ℃.
(a) composition must be the residual oil of the normal pressure residual oil of the various crude oil of underpressure distillation, and viscosity-gravity constant is 0.79～0.87 or 0.790～0.875.Following formula (1) expression of viscosity-gravity constant (V.G.C.) based on ASTMD2501-91,
In the formula, the density when G represents 15 ℃ (g/ml), the kinetic viscosity (mm when V ' represents 100 ℃
2/ s).
The adjustment of this viscosity-gravity constant can mainly be undertaken by the selection or the mixing of crude oil.
If viscosity-gravity constant less than 0.79, is the underpressure distillation residual oil as mineral oil then, be difficult to obtain, if surpass 0.875, then with the combination of (b) composition in, rubber rerum natura (normality rerum natura, thermal ageing rerum natura) just has the possibility of reduction.
(b) composition be the polycyclc aromatic compound amount less than 3 quality %, the mineral oil of flash-point more than 200 ℃, the amount of preferred polycyclc aromatic compound is less than 3 quality %.In Europe, yardstick as the carinogenicity of mineral oil, have by according to (the Institute of Petroleum of Institute of Petroleum(IP), be designated hereinafter simply as IP) the polycyclc aromatic compound amount measured of IP346/92 method, more than 3 quality %, use is restricted, and the value of polycyclc aromatic compound amount described herein is also measured by the IP346/92 method.
Flash-point [C.O.C. (℃)] be necessary for more than 200 ℃, if less than 200 ℃, then and (a) combination of composition, the possibility that reduces rubber rerum natura (particularly thermal ageing rerum natura) is arranged, and and the deterioration of the operating environment that causes of the oil vapour during Rubber processing relation is arranged.As mineral oil with above character, can use by each operations such as solvent treatment, hydrofinishing or hydrogenation decomposition, and the material that obtains of the cut that obtains such as the refining air distillation by various crude oil of dewaxing operation as required, underpressure distillation, diasphaltene operation.
Just (a) composition and (b) blending ratio of composition, with respect to (a) composition of 25～100 quality %, (b) composition is 0～75 quality %.Perhaps with respect to (a) composition of 25～90 quality %, (b) composition is 10～75 quality %.If (a) composition is less than 25 quality %, then rubber rerum natura (normality rerum natura, thermal ageing rerum natura) just has the possibility of reduction.If (a) composition surpasses 90 quality %, then because 100 ℃ kinetic viscosity surpasses 100mm
2/ s, operability reduces, so preferred (a) composition is below the 90 quality %, the more preferably scope of 30～80 quality %.
The preferred rerum natura of rubber processing oil of the present invention is, for density (15 ℃), is 0.90～0.97g/ml, for kinetic viscosity (100 ℃), is 20～100mm
2/ s for flash-point (C.O.C.), is 220～300 ℃.
Then, second rubber combination of inventing for the application describes.
By in rubber, be benchmark with the total composition, cooperate the above-mentioned rubber processing oil of 10～25 quality %, can obtain rubber combination.The kind of this rubber has no particular limits, natural rubber or elastomeric any can.As synthetic rubber, for example can list styrene butadiene rubbers (SBR), vinylbenzene neoprene (SCR), styrene isoprene rubber (SIR), iso-butylene synthetic polyisoprene (IIR), ethylene propylene rubber (EPR), ethylene propylene diene monomer (EPDM) etc.Fragrant family rubber such as wherein preferred SBR, SCR, SIR especially preferably contain the above SBR of 50 quality % or the rubber of natural rubber.
The rubber combination that has cooperated the rubber processing oil of the present invention that obtains like this, the rubber rerum natura at initial stage (normality rerum natura) is good, and excellent heat resistance.
