Description
本発明は、ゴム組成物及び該ゴム組成物を架橋して得られるゴム成形体に関する。 The present invention relates to a rubber composition and a rubber molded product obtained by crosslinking the rubber composition.
自動車、鉄道車両、産業車両、船舶、航空機等の輸送機械に使用される各種機械は、近年、小型軽量化に加えて、高性能であることを同時に求められるケースが増加している。例えば、自動車の分野では、小型軽量化を目的としたＦＦ（フロントエンジン・フロント駆動）車の普及により、またさらに居住空間の拡大により、自動車はエンジンルームの縮小を余儀なくされつつある。このような高性能の機械に使用されるシール部材には、高温で使用しても劣化が小さく、良好な密封性を長く維持し、信頼性や耐熱性に優れることが求められる。 In recent years, various machines used for transportation machines such as automobiles, railway vehicles, industrial vehicles, ships, and airplanes are required to have high performance in addition to miniaturization and weight reduction. For example, in the field of automobiles, automobiles are being forced to reduce engine rooms due to the widespread use of FF (front engine / front drive) vehicles for the purpose of miniaturization and weight reduction, and further expansion of living space. A seal member used in such a high-performance machine is required to have little deterioration even when used at a high temperature, maintain good sealing performance for a long time, and have excellent reliability and heat resistance.
中でも、前記各種機械において、軸受のような回転する部分に使用されるシール材は、高温環境下にさらされることが多いため、耐熱性に優れた合成ゴムが必要とされている。
合成ゴムの耐熱性の向上を図る場合、まず前記ゴム組成物に使用するポリマーの中から所望の耐熱性を備えた素材を選択したり、そのポリマーを加工するのに適した加硫剤、老化防止剤等を選択したりすることが行われている（例えば、特許文献１、２、３参照）。
In particular, in the various machines, a sealing material used for a rotating part such as a bearing is often exposed to a high temperature environment, and therefore, a synthetic rubber having excellent heat resistance is required.
To improve the heat resistance of synthetic rubber, first select a material with the desired heat resistance from the polymers used in the rubber composition, and vulcanizing agents suitable for processing the polymer. An inhibitor or the like is selected (see, for example, Patent Documents 1, 2, and 3).
しかしながら、耐熱性を有する合成ゴムの上市品としては、実質的にはシリコーンゴム系又はフッ素ゴム系に限定されるために選択肢が少なく、これらの合成ゴムは単価が高いため各種機械を製造するメーカーにとっては経済的な負担が大きくなっている。また、新規なポリマーを用いて重合を行ったり、新規な添加剤（例えば、老化防止剤）を用いて、新規な合成ゴムを作製したりすると、開発や製造にかかるコストに加えて、新規な合成ゴムを市場に広める点でもさらに経済的な負担が大きくなるという背景もある。 However, there are few choices for commercially available synthetic rubbers with heat resistance because they are essentially limited to silicone rubbers or fluororubbers, and these synthetic rubbers are expensive and are manufacturers that produce various machines. The economic burden is increasing. In addition, when a new polymer is used for polymerization or a new additive (for example, anti-aging agent) is used to produce a new synthetic rubber, in addition to the development and manufacturing costs, There is also a background that the economic burden is further increased in terms of spreading synthetic rubber to the market.
そこで、本件出願人も、高温で使用しても劣化が小さく、良好な密封性を長く維持し、信頼性や耐熱性に優れるシール部材として、特許文献４記載のような転がり軸受用シール部材を提供している。 Therefore, the applicant of the present invention also uses a rolling bearing seal member as described in Patent Document 4 as a seal member that is small in deterioration even when used at high temperatures, maintains good sealing performance for a long time, and is excellent in reliability and heat resistance. providing.
しかしながら、各種機械では、小型軽量化に加えて、高性能であることを同時に求められるケースが、今後ますます増加していく傾向にあることは明らかであり、小型化に伴って、加工しやすく、且つ耐熱性に優れたシール部材が必要とされている。 However, it is clear that there is a tendency for various machines to be required to have high performance in addition to miniaturization and weight reduction in the future. In addition, a sealing member having excellent heat resistance is required.
本発明は、前記事情に鑑みてなされたものであり、耐熱性に優れたゴム成形体のための、加工性に優れたアクリル酸エステル系のゴム組成物、該ゴム組成物を架橋してなり、耐熱性に優れたゴム成形体並びに該ゴム成形体からなる軸受用シールを提供することにある。 The present invention has been made in view of the above circumstances, and is an acrylic ester-based rubber composition having excellent processability for a rubber molded article having excellent heat resistance, and is obtained by crosslinking the rubber composition. Another object of the present invention is to provide a rubber molded body excellent in heat resistance and a bearing seal made of the rubber molded body.
本発明者らは、前記課題を解決するために、単価がシリコーンゴム系又はフッ素ゴム系の合成ゴムよりも安価なアクリルゴムに着目し、その合成ゴムの耐熱性を向上させることを目的として鋭意検討したところ、ゴム組成物中の第１配合成分としてＰＴＦＥの含有量を多量に含有させ、第２配合成分としてカーボンブラック及びシリカの含有量を特定することで、ゴム組成物の加工性が優れたものでありながら、そのゴム組成物から得られるゴム成形体の耐熱性が有意に向上することを見出し、本発明を完成させた。 In order to solve the above problems, the present inventors have focused on acrylic rubber whose unit price is cheaper than silicone rubber-based or fluororubber-based synthetic rubber, and eagerly aims to improve the heat resistance of the synthetic rubber. As a result of the examination, the rubber composition has excellent processability by containing a large amount of PTFE as the first compounding component in the rubber composition and specifying the content of carbon black and silica as the second compounding component. However, the present inventors have found that the heat resistance of a rubber molded product obtained from the rubber composition is significantly improved, and completed the present invention.

In the present invention, acrylic rubber is used as the polymer. The acrylic rubber may be a commercially available acrylic acid ester polymer or copolymer having a crosslinking point such as a carboxyl group, active chlorine, and epoxy group, and any of these commercially available products can be used in the present invention. . Moreover, there is no limitation in particular also about the kind of acrylic rubber. For example, “Nipol” (trade name) manufactured by Nippon Zeon Co., Ltd. has an active chlorine group such as “AR31”, “AR42W”, “AR54”, etc. as an acrylic ester polymer or copolymer having an epoxy group. Examples of the polymer or copolymer of acrylic ester having “AR71” and “AR72LS” include “AR12” and “AR22” and the like of polymer or copolymer of acrylic ester having a carboxyl group. It is done.
Among these, an acrylate copolymer having a carboxyl group is preferable from the viewpoint of excellent heat resistance and water resistance.
本発明においては、第１配合成分として４フッ化エチレン樹脂（ＰＴＦＥ）を使用することで、アクリルゴムをポリマーとするゴム成形体の耐熱性を向上させることができる。 In this invention, the heat resistance of the rubber molding which uses acrylic rubber as a polymer can be improved by using tetrafluoroethylene resin (PTFE) as a 1st compounding component.
本発明のゴム組成物中において、前記第１配合成分であるＰＴＦＥは、前記アクリルゴム１００重量部に対して、３０〜８０重量部含有される。前記ＰＴＦＥの含有量が３０重量部未満であると、耐熱性を向上することができず、また、８０重量部を超えると、ゴム組成物の粘度が高くなりすぎて、加工性が劣化する。前記ＰＴＦＥの含有量は、ゴム組成物の加工性とゴム成形体の耐熱性が共に優れる観点から、３０〜４０重量部が好ましい。 In the rubber composition of the present invention, PTFE as the first compounding component is contained in an amount of 30 to 80 parts by weight with respect to 100 parts by weight of the acrylic rubber. If the PTFE content is less than 30 parts by weight, the heat resistance cannot be improved, and if it exceeds 80 parts by weight, the viscosity of the rubber composition becomes too high and the processability deteriorates. The content of PTFE is preferably 30 to 40 parts by weight from the viewpoint of excellent processability of the rubber composition and heat resistance of the rubber molded body.
前記ＰＴＦＥとしては、合成ゴムに使用できるものであればよい。また、ＰＴＦＥとしては、アクリルポリマーの分散性の観点から、粉体状のものが好ましい。例えば、旭硝子（株）製の「ＡＧＣ・１６９Ｊ」（粒径は１５μｍ）、住友３Ｍ（株）製の「Ｔ−９２０５」（粒径は８μｍ）が挙げられる。 Any PTFE may be used as long as it can be used for synthetic rubber. PTFE is preferably in the form of powder from the viewpoint of dispersibility of the acrylic polymer. For example, “AGC 169J” (particle size is 15 μm) manufactured by Asahi Glass Co., Ltd., and “T-9205” (particle size is 8 μm) manufactured by Sumitomo 3M Co., Ltd. may be mentioned.
本発明においては、第２配合成分としてカーボンブラック及びシリカからなる群より選ばれる１種又は２種を使用することで、アクリルゴムをポリマーとするゴム組成物の加工性を向上させ、ゴム成形体の強度を保つことができる。 In the present invention, by using one or two selected from the group consisting of carbon black and silica as the second compounding component, the processability of the rubber composition using acrylic rubber as a polymer is improved, and a rubber molded body The strength of can be kept.
前記カーボンブラックとしては、例えば、ＳＡＦカーボンブラック、ＩＳＡＦカーボンブラック、ＨＡＦカーボンブラック、ＦＥＦカーボンブラック、ＧＰＦカーボンブラック、ＳＲＦカーボンブラック、ＦＴカーボンブラック、ＭＴカーボンブラック、アセチレンカーボンブラック、ケッチェンブラック等が挙げられる。これらは単独で又は２種以上を併用することができる。 Examples of the carbon black include SAF carbon black, ISAF carbon black, HAF carbon black, FEF carbon black, GPF carbon black, SRF carbon black, FT carbon black, MT carbon black, acetylene carbon black, and ketjen black. It is done. These can be used alone or in combination of two or more.
前記シリカとしては、珪酸、珪酸塩、二酸化珪素等が挙げられる。また、前記シリカとしては、珪酸、珪酸塩又は二酸化珪素が含まれた材料でもよく、例えば、珪藻土、珪酸塩鉱物、シリカゲル等が挙げられる。これらは単独で又は２種以上を併用することができる。また、シリカの形態としては、粉砕品として使用することが取り扱い性の観点から、好ましい。 Examples of the silica include silicic acid, silicate, silicon dioxide and the like. The silica may be a material containing silicic acid, silicate, or silicon dioxide, and examples thereof include diatomaceous earth, silicate minerals, and silica gel. These can be used alone or in combination of two or more. Moreover, as a form of silica, it is preferable to use it as a pulverized product from the viewpoint of handleability.
本発明のゴム組成物中において、第２配合成分は、前記アクリルゴム１００重量部に対して、２０〜９０重量部含有される。前記第２配合成分の含有量が２０重量部未満であると、ゴム組成物の加工性が劣化して、例えば、表面状態が悪化する傾向があり、また、９０重量部を超えると、ゴム組成物の粘度が高くなり加工性が劣化してしまい、成形体の強度が高くなりすぎる傾向がある。前記第２配合成分の含有量は、ゴム組成物の加工性に優れ、ゴム成形体の強度を保つ観点から、３０〜６０重量部が好ましい。 In the rubber composition of the present invention, the second compounding component is contained in an amount of 20 to 90 parts by weight with respect to 100 parts by weight of the acrylic rubber. If the content of the second compounding component is less than 20 parts by weight, the processability of the rubber composition deteriorates, for example, the surface state tends to deteriorate, and if it exceeds 90 parts by weight, the rubber composition There is a tendency that the viscosity of the product is increased, the workability is deteriorated, and the strength of the molded body is too high. The content of the second compounding component is preferably 30 to 60 parts by weight from the viewpoint of excellent processability of the rubber composition and maintaining the strength of the rubber molded body.
また、本発明のゴム組成物において、前記アクリルゴム１００重量部に対して、第１配合成分と第２配合成分との合計量を５０〜１２０重量部に調整することで、ゴム組成物の加工性及びゴム成形体の耐熱性を共に優れたものとすることができる。前記第１配合成分と第２配合成分との合計量が５０重量部未満とすると、第１配合成分及び第２配合成分のそれぞれの添加効果が出難くなる傾向があり、また、１２０重量部を超えるとアクリルゴムと混練した場合に混練物の粘度が高くなりすぎたり、得られるゴム成形体の強度が高くなりすぎて、加工性が著しく損なわれる傾向がある。したがって、本発明のゴム組成物において、前記第１配合成分と第２配合成分との合計量を５０〜１２０重量部に調整することが好ましい。 In the rubber composition of the present invention, the rubber composition is processed by adjusting the total amount of the first compounding component and the second compounding component to 50 to 120 parts by weight with respect to 100 parts by weight of the acrylic rubber. Both the heat resistance and the heat resistance of the rubber molded body can be improved. If the total amount of the first compounding component and the second compounding component is less than 50 parts by weight, the respective additive effects of the first compounding component and the second compounding component tend to be difficult to appear, and 120 parts by weight When exceeding, when knead | mixing with an acrylic rubber, the viscosity of a kneaded material will become high too much, or the intensity | strength of the rubber molding obtained will become high too much, and there exists a tendency for workability to be impaired remarkably. Therefore, in the rubber composition of the present invention, it is preferable to adjust the total amount of the first compounding component and the second compounding component to 50 to 120 parts by weight.

Various additives such as an agent, a flame retardant, and an ultraviolet absorber can be blended in appropriate amounts within a range that does not impair the effects of the present invention.
架橋剤としては、アクリルゴム用のものであればよく、特に限定はないが、硫黄及び有機過酸化物が用いられる。硫黄としては、例えば、粉末硫黄、沈降硫黄、コロイド硫黄、表面処理硫黄、不溶性硫黄等が挙げられる。また、架橋温度で活性硫黄を放出して架橋する硫黄化合物、例えば、モルホリンジスルフィド、炭素数１〜１８のアルキルフェノ−ルジスルフィド、炭素数１〜１８のテトラアルキルチウラムジスルフィド、ジペンタメチレンチウラムテトラスルフィド、ジメチルジチオカルバミン酸セレン等を加硫促進剤として用いることもできる。 The cross-linking agent is not particularly limited as long as it is for acrylic rubber, but sulfur and organic peroxide are used. Examples of sulfur include powdered sulfur, precipitated sulfur, colloidal sulfur, surface-treated sulfur, insoluble sulfur, and the like.
