Definitions
- the present invention c prior art relating vulcanizing fluorine rubber composition providing a non-colored cured
- vulcanized fluoro rubber is used as a sealing material for plasma generators. Leaks due to the generated particles and deterioration of the material are problematic, and the sealing material is preferably a non-filler, and preferably has transparency so that the dust can be seen at a glance. By simply removing the filler, the vulcanized fluororubber becomes brown transparent or brown opaque, and does not have colorless transparency.
- An object of the present invention is to provide a fluororubber composition which gives a colorless and transparent vulcanizate.
- the present invention is a.
- R 1 and R 2 are an alkyl group having 1 to 3 carbon atoms.
- a vulcanizing fluororubber composition comprising:
- the iodine and / or bromine-containing fluororubber (a) is a polymer in which 0.001 to 10% by weight, preferably 0.01 to 5% by weight of iodine and / or bromine is bonded to carbon of a fluoropolymer.
- the carbon to which iodine or bromine is bonded is preferably not limited to the force at the terminal of the polymer chain, and may be carbon in the main chain, side chain, or branch point.
- the iodine- and / or bromine-containing fluororubber (a) refers to a fluorinated polymer having rubber elasticity at room temperature when vulcanized.
- Conventionally known fluororubbers are included, and typical fluororubbers include vinylidene fluoride / hexafluoropropylene-based (vinylidene fluoride).
- Monofluoroalkyl vinyl ether including those containing a plurality of ether bonds
- Olefin tetrafluoroethylene, ethylene, etc.
- Fluoro rubbers such as fluorosilicone and fluorophosphazene. Examples of iodine and / or bromine containing fluorine rubbers (a) are described, for example, in U.S. Pat. Nos. 4,243,770, 4,035,565 and 4.214.060 (see these disclosures).
- JP-A-53-125491, JP-B-53-4115, and JP-A-59-20310 may be used in addition to the above-mentioned monomer (for example, vinylidene fluoride) and an iodine and / or bromine-containing compound (for example, ICH 2 CF 2 CF 2 ⁇ ).
- CF CF 2
- the molecular weight of the fluororubber (a) is usually 1,000 to 100,000.
- the vulcanizing agent (b) is not particularly limited as long as it is an organic peroxide.
- Specific examples of the vulcanizing agent (b) are 1,1-bis (t-butylperoxy) —3,5,5-trimethylcyclohexane and 2,5-dimethylhexane-1,2,5-dihydroxy peroxide.
- the amount of the vulcanizing agent (b) is 0.1 to 5.0 parts by weight based on 100 parts by weight of the fluororubber (a).
- Component (c) is compound (I) which acts as a stabilizer.
- Compound (I) is, for example, 2-tert-butyl-4-methoxyphenol (m-tert-butyl-p-hydroxyanisole), 3-tert-butyl-4-methoxyphenol, 2-tert-butyl-4-ethoxy-phenol Phenol, 3 overnight, 4-northanolin 4-ethoxyethoxyphenol, 2-tanyanolebutinole 4-propoxyphenol, 3-tert-butyl-4-propioquine Phenol, 2- (1,1-ethylpropyl) -4-methoxyphenol, 3- (1,1-ethylpropyl) 4-methoxyphenol, 2- (1,1-dipropylbutyl) 4-Methoxyphenol, 3- (1,1-dipropylbutyl) -1- 4-methoxyphenol, 2- ( ⁇ , 1-ethylethyl) -4-1ethoxyquinol, 3- (1,1-Je
- the composition may contain a crosslinking aid (d).
- the crosslinking assistant (d) is effective in principle as long as it has a reaction activity for the peroxyl radical and the polymer radical, and the type thereof is not particularly limited.
- Preferred specific examples of the crosslinking assistant (d) include triaryl cyanurate, triaryl noreison anurate, triacryl formal, triaryl retrimelitate, N, N'-in-phenylene bismaleimide, dipropargyl terephthalate.
- the amount of the crosslinking aid (d) is usually 10 parts by weight or less, preferably 0.1 to 5.0 parts by weight, based on 100 parts by weight of the fluororubber (a).
- a small amount of an additive that does not impair transparency may be added. Addition of a small amount of pigment Coloring (colored and transparent) is also possible.
- a method in which the stabilizer (c) is mixed with the vulcanizing agent (b) or the crosslinking assistant (d) and then using an open roll, or a closed method such as a two-dimensional method A method using a type mixer may be used.
- Vulcanization can be performed under the usual vulcanization conditions of fluororubber. For example, after kneading the vulcanizing composition, put it in a mold, press-vulcanize it by holding it at 100 to 200 ° C and 20 to 100 kg / cm2 for 5 to 180 minutes, and then 150 to 300 ° Oven vulcanization is performed by holding in the furnace of C for 0 to 50 hours to obtain a vulcanized rubber.
- the fluorororubber composition of the present invention can be used in a field in which dust is extremely disliked, particularly as a sealing material for a plasma generator in semiconductor production. It can also be used in the food and medical fields.
- Daiel Perflo G A-15 (Iodine-containing fluoro rubber (Tetrafluoroethylene perfluorobutyl ether copolymer), manufactured by Daikin Industries, Ltd.)
- TA IC triallyl isocyanurate
- Example 1 The same procedure as in Example 1 was repeated, except that the components shown in Table 1 were used. Table 1 shows the results. Note that Daiel G-912 (manufactured by Daikin Industries, Ltd.) is an iodine-containing fluororubber (vinylidene fluoride tetrafluoroethylene hexafluoropropylene copolymer), and Co., Ltd.) is an iodine-containing fluororubber (vinylidene fluoride / tetrafluoroethylene / hexafluoropropylene copolymer), and BHT is 2,6-di-tert-butyl-4-methylphenol. .

- Co., Ltd. is an iodine-containing fluororubber (vinylidene fluoride / tetrafluoroethylene / hexafluoropropylene copolymer)
- a vulcanized rubber sheet was obtained in the same procedure as in Example 1, except that the amount of the compound shown in Table 1 was used instead of m-tert-butyl-p-hydroxydisole 250 ppm. The color of the vulcanized rubber sheet was observed, and the total light transmittance was measured. The total light transmittance was measured by DIEECT EEADING HAZE # ⁇ manufactured by Toyo Seiki Seisaku-sho, Ltd. Table 2 shows the results including the results of Example 1 and Comparative Example 1. ⁇ ⁇ 2 is 2-tert-butyl hydroquinone. Table 2
- a vulcanized rubber sheet was obtained in the same manner as in Example 1, except that the amount of m-tert-butyl- ⁇ -hydroxydisole was changed to the amount shown in Table 3. The color of the vulcanized rubber sheet was observed, and the total light transmittance was measured. Table 3 shows the results, including the results of Example 1 and Comparative Example 6. Table 3
