【発明の属する技術分野】
本発明はタイヤ用ゴム組成物及びそれを用いた空気入りタイヤに関し、更に詳しくはウェットスキッドと転がり抵抗とを両立させたゴム組成物及びそれをトレッド部に用いた空気入りタイヤに関する。
【０００２】
【従来の技術】
ジエン系ゴムにシリカを配合することによりゴム組成物のウェット性能向上と転がり抵抗を低減させる技術が知られている。同様にデンプン粒子やセルロース粒子などの極性フィラーをジエン系ゴムに配合することによって同様な効果を得る試みがなされており、補強性の低い極性粒子の配合にてウェット性能が改良されることが知られている（特許文献１及び２参照）。しかしながら、このような配合剤の添加では摩耗性能が大幅に悪化するという欠点がある。
【０００３】
【特許文献１】
特開１９９８−１７７１３号公報
【特許文献２】
特開２００１−８９５９９号公報
【０００４】
【発明が解決しようとする課題】
本発明は、前述の従来技術の現状に鑑み、耐摩耗性を大きく低下させることなく、ウェットスキッド抵抗及び転がり抵抗を両立させたゴム組成物を提供することを目的とする。
【０００５】
【課題を解決するための手段】
本発明に従えば、スチレン−ブタジエン共重合体ゴム（ＳＢＲ）を含むジエン系ゴム１００重量部及び平均粒子サイズが１〜２００μｍのメタ珪酸カルシウムの粉体５〜５０重量部を含んでなるゴム組成物が提供される。
【０００６】
【発明の実施の形態】
本発明者らは、ＳＢＲを主体とする夏仕様の乗用車用ラジアルタイヤ用ゴム配合に、メタ珪酸カルシウムを主成分とする粉体（例えばウォラストナイト、珪灰石）とシランカップリング剤を配合し、メタ珪酸カルシウムの極性基とシランカップリング剤が反応する条件にてゴムの混練りを行い、加硫することによって、所望の物性が得られることを見出した。
【０００７】
本発明のゴム組成物においては、ジエン系ゴム中のＳＢＲの比率が３０重量％以上、好ましくは５０〜１００重量％でＳＢＲとポリブタジエンゴム（ＢＲ）を合わせたゴムの比率は全ゴム量に対して６０重量％以上、好ましくは７５〜１００重量％である。ＳＢＲの配合量が少な過ぎるとｔａｎδのバランスを適正に保ちにくくなるおそれがあるので好ましくない。
【０００８】
本発明において使用するＳＢＲ及びＢＲ以外のジエン系ゴムとしては、例えば天然ゴム（ＮＲ）、ポリイソプレンゴム（ＩＲ）、アクリロニトリル−ブタジエン共重合体ゴムなどをあげることができ、これらは単独又は任意のブレンドとして使用することができる。なお、ＳＢＲ及びＢＲとしては、特に限定はないが、所望の低転動抵抗と耐摩耗性、低温性能とを両立させて向上させるためにはガラス転移温度（Ｔｇ）が−４５℃〜−１５℃の範囲にあることが好ましい。
【０００９】
本発明において使用するメタケイ酸カルシウム粉体は平均粒子サイズが１〜２００μｍ、好ましくは５０〜１００μｍのものをジエン系ゴム１００重量部に対し、５〜５０重量部、好ましくは１０〜３０重量部配合する。この配合量が少な過ぎると所望の効果が得られず、逆に多過ぎると耐摩耗性が悪化するので好ましくない。一方、前記粒子径が大き過ぎると、加硫ゴムの強度が低下するので好ましくない。
【００１０】
本発明において使用するメタケイ酸カルシウムは珪灰石とも呼ばれ、ＳｉＯ４ が２つのＯ原子を共有して一次元無限鎖（ＳｉＯ３ ）ｎ ２ｎ−をつくった巨大イオン構造をしており、ＮＹＣＯ Ｍｉｎｅｒａｌｓ，Ｉｎｃからウォラストナイト（Ｗｏｌｌａｓｔｏｎｉｔｅ）として市販されているものを使用することができる。
【００１１】
本発明に従えば前記ゴム組成物に硫黄及び含硫黄シランカップリング剤を配合するのが好ましい。これらの配合量はメタケイ酸カルシウムの配合量に対し５〜２５重量％、好ましくは７〜１２重量％である。この配合量が少な過ぎると所望のカップリング効果が得られにくいので好ましくなく、逆に多過ぎるとゴムが加工中に早期加硫してしまうおそれがあるので好ましくない。
【００１２】
本発明に従ったゴム組成物は一般的な方法で製造することができるが、ジエン系ゴム及びメタ珪酸カルシウムを含み、硫黄及び加硫助剤を含まない配合成分を、放出時の最高到達温度が１４０℃以上となるように密閉式混練機で混練し、その混合より後の加工段階において、ジエン系ゴムとメタ珪酸カルシウムを含むゴム組成物を硫黄及び加硫助剤と共に混練りするのが好ましい。
【００１３】
本発明に係るゴム組成物には、前記した成分に加えて、カーボンブラックやシリカなどのその他の補強剤（フィラー）、加硫促進剤、各種オイル、老化防止剤、可塑剤などのタイヤ用、その他一般ゴム用に一般的に配合されている各種添加剤を配合することができ、かかる添加剤は一般的な方法で混練して組成物とし、加硫するのに使用することができる。これらの添加剤の配合量は本発明の目的に反しない限り、従来の一般的な配合量とすることができる。
【００１４】
【実施例】
以下、実施例によって本発明を更に説明するが、本発明の範囲をこれらの実施例に限定するものでないことはいうまでもない。
【００１５】
実施例１及び比較例１〜３

【発明の効果】
以上の通り、本発明に従えば、比較例に比べて低温ｔａｎδが高く、高温ｔａｎδが低く、低温反発弾性が低く、高温反発弾性が高く、そして耐摩耗性能の大きな低下が起らないゴム組成物を得ることができる。このゴム組成物をトレッド部に用いて空気入りタイヤを製造することによって、ウェットスキッドと低転がり抵抗が両立したタイヤを得ることができ、従来のシリカ配合よりもウェット性能の向上と転がり抵抗の低減の効果が大きく、シリカ以外の極性フィラー（セルロース粉体）よりも耐摩耗性の低下度合いが著しく小さいタイヤを得ることができる。[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rubber composition for tires and a pneumatic tire using the same, and more particularly to a rubber composition having both wet skid and rolling resistance and a pneumatic tire using the same in a tread portion.
[0002]
[Prior art]
A technique for improving the wet performance of a rubber composition and reducing rolling resistance by blending silica with a diene rubber is known. Similarly, attempts have been made to obtain the same effect by blending polar fillers such as starch particles and cellulose particles with diene rubber, and it is known that wet performance is improved by blending polar particles with low reinforcing properties. (See Patent Documents 1 and 2). However, the addition of such a compounding agent has a drawback that the wear performance is greatly deteriorated.
[0003]
[Patent Document 1]
JP 1998-17713 [Patent Document 2]
Japanese Patent Laid-Open No. 2001-89599 [0004]
[Problems to be solved by the invention]
An object of the present invention is to provide a rubber composition that achieves both wet skid resistance and rolling resistance without greatly reducing the wear resistance.
[0005]
[Means for Solving the Problems]
According to the present invention, a rubber composition comprising 100 parts by weight of a diene rubber containing styrene-butadiene copolymer rubber (SBR) and 5 to 50 parts by weight of calcium metasilicate powder having an average particle size of 1 to 200 μm. Things are provided.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The inventors of the present invention blended a powder (for example, wollastonite and wollastonite) containing calcium metasilicate as a main component and a silane coupling agent into a summer tire radial tire rubber composition mainly composed of SBR. The present inventors have found that desired physical properties can be obtained by kneading and vulcanizing rubber under conditions where the polar group of calcium metasilicate reacts with the silane coupling agent.
[0007]
In the rubber composition of the present invention, the proportion of SBR in the diene rubber is 30% by weight or more, preferably 50 to 100% by weight, and the proportion of rubber comprising SBR and polybutadiene rubber (BR) is based on the total amount of rubber. 60% by weight or more, preferably 75 to 100% by weight. If the amount of SBR is too small, it may be difficult to keep the balance of tan δ properly.
[0008]
Examples of diene rubbers other than SBR and BR used in the present invention include natural rubber (NR), polyisoprene rubber (IR), acrylonitrile-butadiene copolymer rubber, and the like. Can be used as a blend. SBR and BR are not particularly limited, but a glass transition temperature (Tg) is −45 ° C. to −15 in order to improve both desired low rolling resistance, wear resistance, and low temperature performance. It is preferable to be in the range of ° C.
[0009]
The calcium metasilicate powder used in the present invention has an average particle size of 1 to 200 μm, preferably 50 to 100 μm, based on 100 parts by weight of diene rubber, preferably 5 to 50 parts by weight, preferably 10 to 30 parts by weight. To do. If the blending amount is too small, the desired effect cannot be obtained. On the contrary, if the blending amount is too large, the wear resistance deteriorates, which is not preferable. On the other hand, when the particle diameter is too large, the strength of the vulcanized rubber is lowered, which is not preferable.
[0010]
The calcium metasilicate used in the present invention is also called wollastonite, and has a giant ionic structure in which SiO 4 shares two O atoms to form a one-dimensional infinite chain (SiO 3 ) n 2n- , and NYCO Minerals , Inc., commercially available as Wollastonite.
[0011]
According to the present invention, it is preferable to add sulfur and a sulfur-containing silane coupling agent to the rubber composition. These compounding quantities are 5-25 weight% with respect to the compounding quantity of calcium metasilicate, Preferably they are 7-12 weight%. If the amount is too small, the desired coupling effect is difficult to obtain, which is not preferable. On the other hand, if the amount is too large, the rubber may be vulcanized early during processing, which is not preferable.
[0012]
Although the rubber composition according to the present invention can be produced by a general method, a compound component containing a diene rubber and calcium metasilicate, and not containing sulfur and a vulcanization auxiliary agent, has a maximum temperature at the time of release. Kneading with a closed kneader so that the temperature is 140 ° C. or higher, and kneading a rubber composition containing diene rubber and calcium metasilicate together with sulfur and a vulcanization aid in the processing stage after the mixing. preferable.
[0013]
For the rubber composition according to the present invention, in addition to the above-described components, other reinforcing agents (fillers) such as carbon black and silica, vulcanization accelerators, various oils, anti-aging agents, and plasticizers for tires, In addition, various additives generally blended for general rubber can be blended, and such additives can be kneaded by a general method to form a composition and used for vulcanization. As long as the amount of these additives is not contrary to the object of the present invention, a conventional general amount can be used.
[0014]
