Description

本発明は、シリカとシリカの補強性を高める有機珪素化合物とを含むゴム組成物及びそれを用いた空気入りタイヤに関する。   The present invention relates to a rubber composition containing silica and an organosilicon compound that enhances the reinforcing property of silica, and a pneumatic tire using the rubber composition.

近年、ゴム成分として天然ゴム及び／又は合成ゴム等のジエン系ゴムにシリカ等の無機充填剤を配合することにより、低燃費性と湿潤路面でのグリップ性とを両立させたタイヤトレッド用の各種ゴム組成物が数多く提案されている。
補強性無機充填剤としてシリカを用いた場合、従来のカーボンブラックを用いた場合と比較すると、シリカ−ゴム成分の結合は、カーボンブラック−ゴム成分の結合と比較して弱くなる。
そこで、シリカを配合したゴム組成物は、シリカ−ゴム成分の結合を補強するため、通常、有機珪素化合物であるシランカップリング剤が用いられる。即ち、シランカップリング剤は、シリカ−ゴム成分の結合を強化し、タイヤトレッドの低燃費性、破壊特性や耐摩耗性を向上させる。特に、その分子内にアルコキシシリル基及びイオウの双方を含む有機珪素化合物であるシランカップリング剤は、加硫反応によりシリカとゴム成分とを容易に結合させるため、好適に用いられている。 In recent years, various types of tire treads that achieve both low fuel consumption and grip on wet road surfaces by blending an inorganic filler such as silica with a diene rubber such as natural rubber and / or synthetic rubber as a rubber component. Many rubber compositions have been proposed.
When silica is used as the reinforcing inorganic filler, the silica-rubber component bond is weaker than the carbon black-rubber component bond as compared to the conventional carbon black.
Therefore, a rubber composition containing silica usually uses a silane coupling agent, which is an organosilicon compound, in order to reinforce the silica-rubber component bond. That is, the silane coupling agent reinforces the silica-rubber component bond and improves the fuel efficiency, fracture characteristics, and wear resistance of the tire tread. In particular, a silane coupling agent that is an organosilicon compound containing both an alkoxysilyl group and sulfur in the molecule is preferably used because silica and a rubber component are easily bonded by a vulcanization reaction.

しかし、その分子内にアルコキシシリル基を有する有機珪素化合物であるシランカップリング剤は、シリカと反応する際に、アルコールを発生する。生じたアルコールは、ゴム中で揮発するため、押出成形した未加硫ゴムの内部で発泡し（ブリスターが生成し）、ゴムの補強性、寸法安定性及び生産性を低下させるという問題がある。また、環境面での配慮からも、揮発性アルコールの放出を減少させることが望まれている。
このような問題を解決するために、アルコールの放出を減少させる有機珪素化合物である種々のシランカップリング剤が提案されている。（特許文献１〜６参照）しかし、これらの化合物では、揮発性アルコールの放出の減少と、シリカとの反応性の確保との両立が不十分であった。 However, a silane coupling agent that is an organosilicon compound having an alkoxysilyl group in the molecule generates an alcohol when it reacts with silica. Since the generated alcohol volatilizes in the rubber, there is a problem that it is foamed inside the extruded unvulcanized rubber (a blister is generated), and the reinforcing property, dimensional stability and productivity of the rubber are lowered. Moreover, from the environmental consideration, it is desired to reduce the emission of volatile alcohol.
In order to solve such problems, various silane coupling agents, which are organosilicon compounds that reduce the release of alcohol, have been proposed. (See Patent Documents 1 to 6) However, these compounds are insufficient in coexistence of a decrease in the release of volatile alcohol and ensuring reactivity with silica.

表１から明らかなように、実施例１〜６のゴム組成物は比較例１〜２のゴム組成物比べて、硬さ、破壊特性や反発弾性を損ねることなく、ムーニー粘度を低下させた。特にポーラス率を大幅に低減させたので、未加硫ゴム組成物の押出作業性が著しく改良された。   As is apparent from Table 1, the rubber compositions of Examples 1 to 6 decreased the Mooney viscosity without impairing the hardness, fracture characteristics, and resilience compared to the rubber compositions of Comparative Examples 1 and 2. In particular, since the porosity was greatly reduced, the extrusion workability of the unvulcanized rubber composition was significantly improved.

本発明のゴム組成物は、乗用車用、小型トラック用、軽乗用車用、軽トラック用及び大型車両用等の各種空気入りタイヤ、特に空気入りラジアルタイヤのトレッド用部材、サイドウォール用部材として好適に用いられる。   The rubber composition of the present invention is suitable for various pneumatic tires for passenger cars, light trucks, light passenger cars, light trucks and large vehicles, particularly as tread members and sidewall members for pneumatic radial tires. Used.
