Definitions
- the present invention relates to a hydrogenated NBR composition. More particularly, the present invention relates to a hydrogenated NBR composition suitably used as a molding material for an intake-hold gasket that is an automobile engine part.
- the hydrogenated NBR which has been used as a conventional material, has an iodine value of 28 or less, which has a concern for heat resistance and the like.
- the heat resistance is improved, it can not be denied that the low temperature characteristics (e.g., low temperature-evaluated by the compression set at 30 ° C) tend to cause deterioration.
- the product if the product is exposed to a low-temperature operating environment, it may cause the product to leak, which may lead to oil leakage in the case of a sealing material, and the product function will not be satisfied.
- Patent Document 1 Japanese Patent Application Publication No. 2001-288303
- a hydrogenated NBR composition having both heat resistance and cold resistance, a hydrogenated NBR having an Atari port-tolyl content of 15 to 30% by weight and a specific surface area of 200 m 2 / g or less.
- a hydrogenated NBR composition which contains white carbon and organic peroxides, preferably further containing a polyfunctional unsaturated compound and Z or carbon black.
- this hydrogenated NBR composition achieves the intended purpose, it has a low acrylonitrile content! /, And the polymer swells in the use environment exposed to oil and fuel in the case of a gasket around the engine, etc. It is difficult to use, and new problems have been seen.
- Patent Document 2 Japanese Patent Application Laid-Open No. 2000-212333
- the object of the present invention is to further improve the oil resistance and the fuel oil resistance in addition to the heat resistance and the cold resistance, even when the hydrogenated NBR having an iodine value of less than 32 is used.
- Water that can be suitably used as a molding material for Gin's Intake-hold gasket An object of the present invention is to provide an NBR composition.
- a compelling object of the present invention is to use 100 parts by weight of hydrogenated NBR or a blend of hydrogenated NBR having an acrylonitrile content of 25 to 45% by weight and an iodine value of 20 to 65, and a nitrogen adsorption specific surface area of 30.
- the hydrogenated NBR yarn composition according to the present invention can be used at low temperature by using two types of carbon black in combination, even when using a hydrogenated NBR having an iodine value of 20 or more and less than 32. At the same time it is possible to simultaneously maintain the elasticity and to be compatible with the heat resistance and cold resistance judged by the compression set, and it is further oil resistant (resistance to oils such as No. 3 oil and other general purpose engine oil etc.) and resistance These products provide excellent crosslinks in terms of resistance to fuel oils such as fuel oil C and other general-purpose commercial gasolines, so gaskets for automobile engine inte-holds and seals especially around automobile and mission systems. It can be suitably used as a molding material for parts and the like.
- the hydrogenated NBR one having an AN content of 25 to 45% by weight, preferably 30 to 40% by weight and an oxygen number of 20 to 65, preferably 32 to 60 is used.
- an iodine value of 20 or more and less than 32 can also be used. If the AN content is less than the above, oil and fuel resistance are inferior, and oil leakage of the product occurs at high temperatures. On the other hand, when the AN content is higher than this, the low temperature characteristics are impaired and an oil leak occurs at low temperature. Also, those with low iodine value will also lose low temperature properties and cause oil leakage at low temperatures. On the other hand, those with higher iodine value will lose heat resistance.
- hydrogenated NBR or a blend 100 weight per nitrogen adsorption specific table area 30 ⁇ 130 (X 10 3 m 2 / kg), preferably 35 ⁇ 90 (X 10 3 m 2 / kg) of furnace black, such as HAF, FEF, SAF, SRF carbon black, preferably about 10 to 70 parts by weight, preferably about 20 to 60 parts by weight of HAF or FEF carbon black, and nitrogen adsorption specific surface area of 5 to 15 X 10 3 m 2 / kg) of a thermal black, eg, about 10 to 80 parts by weight, preferably 20 to 80 parts by weight of MT carbon black, provided that the total amount is about 30 to 150 parts by weight, Preferably, it is used in a proportion of 40 to 120 parts by weight.
- furnace black such as HAF, FEF, SAF, SRF carbon black
- the reinforcing effect is high !, and the use ratio of furnace black less than this, the strength and elongation of the rubber become smaller, and the heat resistance also becomes impaired.
- the proportion of thermal black used is less than this range, the compression set resistance at low temperatures will deteriorate, and oil leakage will tend to occur at low temperatures.
- these carbon blacks are used in a proportion higher than this, the kneadability and curability of the rubber will both decrease.
- ester plasticizers include dibutyl phthalate, di (2-ethylhexyl) phthalate, dioctyl phthalate, di (2-ethylhexyl) adipate, di (butoxyethoxy ethyl) adipate, di 2-Ethyl hexyl) azelate, dibutyl sebacate, dibasic carboxylic acid ester such as di (2-ethyl hexyl) sebacate, tri (2-ethyl hexyl) phosphate, triphenyl-nore phosphate, cresino resiphene-nore phosphate And phosphate esters such as tricresinole phosphate, and products manufactured by Adekagas Co., Ltd. RS 107, RS 700, RS 705, P 200 and the like.
- ester-based plasticizers are each preferably 2 to 2 parts by weight per 100 parts by weight of hydrogenated NBR or a blend thereof. It is used in a proportion of 23 parts by weight, preferably 7 to 17 parts by weight. If the proportion used is lower than this, oil resistance and fuel oil resistance will be impaired, and oil leakage will occur in the product, while if it is used at higher proportions, the low temperature characteristics and oil resistance etc. will be improved. Heat resistance will be lost.
- Crosslinking of a hydrogenated NBR compounded with two types of carbon black and an ester plasticizer is carried out using an organic peroxide.
- organic peroxide examples include di-tert-butyl peroxide, dicumyl peroxide, tert-butyl tamyl peroxide, 1,1-di (tert-butylperoxy) -3,3,5.
- polyfunctional unsaturated compounds such as triallyl (iso) cyanurate, trimethylol propane tri (meth) atalylate, and triallyl trimellitate are hydrogenated.
- NBR Or about 0.5 to 10 parts by weight, preferably about 2 to 8 parts by weight, per 100 parts by weight of the blend.
- the compounding of the polyfunctional unsaturated compound is effective to further improve the heat resistance, particularly, the compression set at that time. However, if it is used at a rate higher than this, rubber elasticity and elongation decrease.
- Preparation of the composition includes, in addition to the above-mentioned components, processing aids such as stearic acid, palmitic acid, and norafin wax, acid acceptors such as zinc oxide, magnesium oxide and hyacintal site, antiaging
- processing aids such as stearic acid, palmitic acid, and norafin wax
- acid acceptors such as zinc oxide, magnesium oxide and hyacintal site
- antiaging After various additives generally used in the rubber industry such as additives are appropriately added as necessary, they are kneaded by using a kneader such as intermixer, kneader or Banbury mixer or an oven roll. Vulcanization takes place, injection molding machine, compression The heat treatment is generally performed by heating at about 150 to 200 ° C. for about 3 to 60 minutes using a molding machine, vulcanization press, etc., and further heating at about 120 to 200 ° C. for about 1 to 24 hours if necessary. Secondary vulcanization is also performed.
