Definitions
- the present invention relates to a blend rubber composition, and more particularly to a blend rubber composition that can be suitably used for oil seals, rubber products, and seal parts.
- NBR is a copolymer-based synthetic rubber of acrylonitrile and butadiene, and is known to have excellent cold resistance, oil resistance, and molding processability. For this reason, it is used as a sealing material for oil seals, O-rings, knockers, etc. in a wide range of fields such as automobiles and industrial machinery industries.
- HNR hydrogenated tolyl rubber
- Non-patent documents 1 and 2 have reported high hardness.
- the rubber obtained from this polymer alloy is certainly high in strength and very excellent in wear resistance. It has the disadvantage of being inferior in mold releasability and cannot be said to be suitable as a sealing material. was there.
- Non-Patent Document 1 Saito, Y., Fujino, A., Ikeda, A .: SAE Technical Parer Series, 890359 (198 9)
- Non-Patent Document 2 Rubber Industry Handbook No. 4 (Japan Rubber Association), published in 1994, page 99
- Patent Document 1 JP 2001-032845 NBR is used for a pressure-resistant O-ring seal.
- Patent Document 2 JP 2000-017110 NBR rubber composition is used as a seal for a shock absorber of a vehicle to ensure slidability.
- an object of the present invention is to provide a blend rubber composition that is easy to mold and has excellent wear resistance.
- the present invention also uses a blend rubber composition that is easy to mold and has excellent wear resistance.
- the invention according to claim 2 is selected from the group consisting of metal alloy, hydrogenated tolyl rubber (HNBR), zinc metal or zinc compound and methacrylic acid (MMA), or poly zinc methacrylate.
- HNBR hydrogenated tolyl rubber
- MMA methacrylic acid
- poly zinc methacrylate poly zinc methacrylate.
- the invention according to claim 3 is the blend rubber composition according to claim 1 or 2, characterized in that the polymer alloy has a CN content of 18 to 44% by weight and an iodine value of 7 to 56mgZl00mg.
- the invention of claim 4 is used as a sealing material.
- the invention according to claim 5 is the blend rubber composition according to claim 4, which is used as one or more sealing materials for pressure resistance, sliding or exercise. The invention's effect
- the obtained blended rubber composition is used in any one or more sites for pressure resistance, sliding, and exercise such as oil seals, O-rings, and packings. Effective as a sealing material.
- an acrylonitrile-tolyl-butadiene rubber having an acrylonitrile content of 15 to 48% can be used.
- those having an acrylonitrile content of 15 to 35% are preferable, and therefore low- Any of a tolyl content (15 to 24%), a medium-tolyl content (25 to 30%), and a medium to high-tolyl content (31 to 35%) can be preferably used.
- the polymer alloy used in the present invention is obtained by mixing and dispersing methacrylic acid (MMA) in hydrogenated-tolyl rubber (HNBR).
- HNBR hydrogenated tolyl rubber
- MMA methacrylic acid
- HNBR hydrogenated tolyl rubber
- MMA methacrylic acid
- 'A product obtained by dispersing is preferred.
- the mixing / dispersing can be performed by a mixer, a homogenizer, an ultrasonic disperser or the like, and is preferably highly dispersed.
- the polymer alloy preferably has a CN content of 18 to 44 wt% and an iodine value of 7 to 56mgZl00mg. If the CN content and iodine value are in the above ranges, the effect of improving the wear resistance of the present invention is obtained, which is preferable.
- Powerful polymer alloys can be obtained as commercially available products such as Zeoferte ZSC-2395 and ZSC-2295 manufactured by Nippon Zeon Co., Ltd.
- the blending ratio of NBR and polymer alloy is a ratio of 10% to 90% by weight of polymer alloy with respect to 90% to 10% by weight of NBR. If NBR exceeds 90% by weight and polymer alloy is less than 10% by weight, mold releasability is good, but there is a problem of lack of wear resistance, and NBR is less than 10% by weight and polymer alloy is 90% by weight. If the weight percentage is exceeded, the wear resistance is good, but there is a problem that the mold releasability is insufficient, and none of the problems of the present invention can be solved.
- the blend rubber composition of the present invention contains a vulcanizing agent (for example, sulfur, sulfur monochloride, selenium, Inorganic vulcanizing agents such as Lulu; organic vulcanizing agents such as sulfur-containing organic compounds, dithiocarbamate and oximes; dicumyl peroxide, 2,5-dimethyl-2,5-di (tert-butyl per Oxy) hexane, benzoyl peroxide, dilauroyl peroxide, organic peroxides such as 1,3-di (tert-butylperoxyisopropyl) benzene, etc.), vulcanization accelerators (eg, acid Metal oxides such as zinc, activated zinc white, surface-treated zinc white, composite zinc white, and magnesium oxide; metal carbonates such as zinc carbonate; metal hydroxides such as calcium hydroxide and calcium; stearin Organic activators such as acids), vulcanization accelerators (eg sulfenamides, thiura), a
- the kneaded material is generally subjected to press vulcanization performed at about 150 to 200 ° C for about 3 to 60 minutes and oven vulcanization (secondary vulcanization) performed at about 100 to 180 ° C for about 0.5 to 5 hours. Sulfur) is then vulcanized.
- the blend rubber composition of the present invention is used as a sealing material, and is preferably used as one or more sealing materials for pressure resistance, sliding or movement.
- the seal material includes static seal and dynamic seal! / And misalignment.
- test piece was used for normal state physical property measurement and wear resistance test.
- a 10-point average roughness R was measured using a surface roughness profile measuring machine (manufactured by Toyo Seimitsu), and the wear resistance was evaluated according to the following criteria based on the wear depth after the test. .
- the mold releasability after test piece vulcanization was evaluated according to the following criteria using a heat press at 170 ° C for 20 minutes.
