Description
The present invention relates to rubber materials, more specifically a kind of nitrile rubber.
Background technology
Nitrile rubber, also known as butadiene one acrylic-nitrile rubber, is called for short NBR, mean molecule quantity about 700,000. Canescence, to light yellow bulk or powdery solid, relative density 0.95��1.0, is dissolved in ethyl acetate, butyl acetate, chlorobenzene, butanone etc. Nitrile rubber has excellent oil resistivity, and its oil resistivity is only second to thiorubber. and fluorubber, and the wearability having and air-tightness. The shortcoming of nitrile rubber is weak to ozone and aromatic series, halogenated hydrocarbons, ketone and esters solvent, is unfit to do insulant. Thermostability is better than butadiene-styrene rubber, neoprene, can 120 DEG C of long-term works. Air-tightness is only second to butyl rubber. The performance of nitrile rubber is affected by acrylonitrile content, and along with acrylonitrile content increases, hot strength, thermostability, oil resistivity, air-tightness, hardness improve, but elastic, tolerance to cold reduction. Nitrile rubber ozone resistance performance is not good, and resistance to water is better.
Just because of nitrile rubber has so excellent performance, so the current domestic research and development much carrying out nitrile rubber, patent application if application number is 200810229506.4 discloses a kind of nitrile rubber, it is made up of rubber, vulcanizing agent, packing strengthening agent, plasticizer, age resistor and auxiliary agent, mass fractions relative is, butyronitrile rubber NBR100 part; Stearic acid dosage 1-20 part, amount of peroxide 5-20 part, carbon black loading 0.1-100 part, age resistor TMDQ2.0 part, surplus is auxiliary agent. Its object is to provide a kind of high rigidity, low compression deformation, thermostability and the good nitrile rubber of tolerance to cold.
And for example application number be 201210515994.1 patent application disclose a kind of nitrile rubber binder, it is by following component by weight, sebacic acid dimethyl ester 7-12 part, nitrile rubber 5-9 part, Colophonium 8-11 part, benzothiazole mercaptan 6-14 part, carbamide 6-13 part, hexamethylenamine 5-7 part, diethyl oxalate 3-9 part, phenolic resin 4-8 part, surplus is water. It is high that its goal of the invention is to provide a kind of adhesion strength, thermostability, the nitrile rubber of oil resistivity and good weatherability.
But its ozone resistance of the nitrile rubber after above-mentioned improvement is not good, it is desirable to provide the more ozone resisting nitrile rubber of one.
