The proportioning of table 1 embodiment 1～embodiment 3 Raws and the mechanical property of rubber composite
Conclusion: temperature can be found out the impact of rubber composite mechanical property from above-mentioned table, the highest under mechanical property room temperature by the hydrogenated nitrile-butadiene rubber composites of the single enhancing of hydroxide monomethyl zinc acrylate resin, the ionization that is the ionic polymer by generating due to it strengthens hydrogenated butyronitrile, rising along with temperature, Intermolecular Forces weakens comparatively fast, and the mechanical property of material shows the phenomenon faster that declines.Although relatively low under the mechanical property room temperature of the hydrogenated butyronitrile matrix material being strengthened by pure carbon black physical action, but its tensile strength and tear strength are slower with the rising decay of temperature, in 80 ~ 100 ℃ of temperature ranges, there is the phenomenon that maintains an equal level in the mechanical property of two kinds of single enhancement rubber composites.After temperature is higher than 100 ℃, the hydrogenated nitrile-butadiene rubber composites that the tensile strength of the hydrogenated nitrile-butadiene rubber composites of the single enhancing of hydroxide monomethyl zinc acrylate resin and tear strength strengthen lower than carbon black.When adopting hydroxide monomethyl zinc acrylate resin and carbon black to mix collaborative enhancing hydrogenated butyronitrile, the room-temperature mechanical property of rubber composite is excellent, and along with the rising of temperature, mechanical property decay is slower, and all the time higher than arbitrary single enhancement type rubber composite.Under the high temperature of 150 ℃, the collaborative successful strengthening is better than the effect of single enhancing, shows excellent mechanical property, and resistance to elevated temperatures is better.With the packing element of the two the collaborative rubber composite processing strengthening, can under oily media environment, 170 ℃, the operating mode of 30 ~ 60MPa, show good sealing effectiveness, can long term operation use.
The above, be only the specific embodiment of the present invention, is not limited to this, is anyly familiar with those skilled in the art in the technical scope that this patent discloses, and can expect easily changing or replacing, within all should being encompassed in protection scope of the present invention.
