Description
本発明は、シリカなどの水酸基を有する無機充填剤が配合されたタイヤトレッド用ゴム組成物に関するものである。 The present invention relates to a rubber composition for a tire tread in which an inorganic filler having a hydroxyl group such as silica is blended.
水酸基を有する無機充填剤配合のゴム組成物は、シランカップリング剤と組み合わせることにより、一般的なカーボンブラック配合のゴム組成物に近い又はそれ以上の摩耗性などの補強性を発揮し、また、湿潤時のグリップ性を向上させると共に転がり抵抗を低減して、安全性と低燃費性を発揮する。特に、該無機充填剤としてシリカを配合した場合、補強性と湿潤時グリップ性と転がり抵抗とのバランスに優れるので、乗用車用タイヤのトレッドゴム配合として利用されている。 A rubber composition containing an inorganic filler having a hydroxyl group, when combined with a silane coupling agent, exhibits reinforcing properties such as wear properties close to or higher than that of a general carbon black compounded rubber composition, Improves grip when wet and reduces rolling resistance to demonstrate safety and fuel efficiency. In particular, when silica is blended as the inorganic filler, it is used as a tread rubber blend for passenger car tires because it has a good balance of reinforcing properties, gripping properties when wet and rolling resistance.
このようなシリカを始めとする水酸基含有無機充填剤は、カーボンブラックに比べて極性が高く、そのため、ゴム組成物の配合時に粘度が高くなって加工性が劣り、あるいはまた分散が悪いため、シランカップリング剤がシリカ表面の極性を低減し、加工性や分散性を改良する役割を持っている。しかしながら、それでも加工性や分散性は不十分であり、上記したタイヤ性能を依然十分に引き出せないという問題がある。この問題を解決するため、一般的には、加工助剤を添加することによりゴム組成物の粘度を低下させて加工性を改善することがなされているが、加工性と上記したタイヤ性能を高次元でバランスさせるという点で未だ不十分なものであった。 Such inorganic fillers containing a hydroxyl group such as silica have a higher polarity than carbon black. Therefore, when the rubber composition is blended, the viscosity becomes high and the processability is poor or the dispersion is poor. The coupling agent has the role of reducing the polarity of the silica surface and improving processability and dispersibility. However, the processability and dispersibility are still insufficient, and there is a problem that the above-described tire performance still cannot be sufficiently obtained. In order to solve this problem, generally, by adding a processing aid, the viscosity of the rubber composition is lowered to improve the processability, but the processability and the tire performance described above are improved. It was still inadequate in terms of balancing in dimension.
例えば、特許文献１には、シリカ及びゴム成分を含む混合物に炭素数１０〜２０の脂肪酸金属塩を添加すること、及び該脂肪酸金属塩として脂肪酸亜鉛や脂肪酸カリウムを使用することが提案されている。しかしながら、加工助剤として脂肪酸亜鉛を用いた場合、粘度低減効果は大きく加工性には優れるものの、摩耗性や高歪み時での弾性率などの補強性に劣り、加工性とタイヤ性能の両立が不十分である。また、脂肪酸カリウムを用いた場合、加工性の改良効果という点で不十分である。 For example, Patent Document 1 proposes adding a fatty acid metal salt having 10 to 20 carbon atoms to a mixture containing silica and a rubber component, and using fatty acid zinc or fatty acid potassium as the fatty acid metal salt. . However, when fatty acid zinc is used as a processing aid, the effect of reducing viscosity is large and excellent in workability, but it is inferior in reinforcement properties such as wearability and elastic modulus at high strain, and both workability and tire performance are compatible. It is insufficient. Moreover, when fatty acid potassium is used, it is inadequate in the point of the improvement effect of workability.
また、特許文献２には、シリカを配合したゴム組成物に加工助剤としてポリペンタエリスリトールの脂肪酸エステルを添加することが提案され、特許文献３には、極性基含有ジエン系ゴムを主成分とするゴム成分、シリカ、シランカップリング剤、及びシリル化剤を含有するゴム組成物に、加工助剤としてポリエーテル系重合体を添加することが提案され、更に、特許文献４には、シリカを配合したゴム組成物に、加工助剤としてアルコキシシロキサンなどのポリシロキサンを添加することが提案されているが、これらはいずれも加工性の改良効果という点で不十分である。
本発明は、以上の点に鑑みてなされたものであり、水酸基を有する無機充填剤配合のゴム組成物において、配合時の加工性とタイヤ性能を高次元でバランスさせることのできるタイヤトレッド用ゴム組成物を提供することを目的とする。 The present invention has been made in view of the above points. In a rubber composition containing an inorganic filler having a hydroxyl group, a rubber for tire tread capable of balancing workability and tire performance at the time of blending at a high level. An object is to provide a composition.
本発明者は、上記課題を解決するために鋭意検討した結果、水酸基を有する無機充填剤配合のゴム組成物に対し、加工助剤として、脂肪酸カルシウム及び／又は脂肪酸カリウムと、脂肪酸アミド及び／又は脂肪酸エステルとの混和物からなるものを用いることにより、配合時の加工性とタイヤ性能とを高次元でバランスさせることができるのを見出し、本発明を完成するに至った。 As a result of intensive studies to solve the above problems, the present inventor, as a processing aid, for a rubber composition containing an inorganic filler having a hydroxyl group, fatty acid calcium and / or fatty acid potassium, fatty acid amide and / or By using what consists of a mixture with fatty acid ester, it discovered that the workability at the time of mixing | blending and tire performance could be balanced in high dimension, and came to complete this invention.
すなわち、本発明に係るタイヤトレッド用ゴム組成物は、（Ａ）ジエン系ゴム、（Ｂ）水酸基を有する無機充填剤、（Ｃ）シランカップリング剤、並びに、（Ｄ）炭素数８〜２４の脂肪酸カルシウム及び炭素数８〜２４の脂肪酸アミド、又は、炭素数８〜２４の脂肪酸カリウム及び炭素数８〜２４の脂肪酸エステル、を含有するものである。 That is, the rubber composition for a tire tread according to the present invention includes (A) a diene rubber, (B) an inorganic filler having a hydroxyl group, (C) a silane coupling agent, and (D) a carbon number of 8 to 24. It contains fatty acid calcium and a fatty acid amide having 8 to 24 carbon atoms, or a fatty acid potassium having 8 to 24 carbon atoms and a fatty acid ester having 8 to 24 carbon atoms .
また、本発明のタイヤトレッド用ゴム組成物においては、前記（Ａ）成分のジエン系ゴム１００重量部に対し、前記（Ｄ）成分の脂肪酸金属塩と脂肪酸誘導体を合計量で０．５〜１０重量部含有することが好ましい。 In the tire tread rubber composition of the present invention, the total amount of the fatty acid metal salt and fatty acid derivative of the component (D) is 0.5 to 10 with respect to 100 parts by weight of the diene rubber of the component (A). It is preferable to contain by weight.
本発明によれば、加工助剤として上記した特定の脂肪酸金属塩と脂肪酸誘導体とを併用したことにより、カーボンブラックよりも極性の高い水酸基含有無機充填剤を、かかる比較的極性の高い官能基を有する脂肪酸金属塩及び脂肪酸誘導体により親和性を高めて分散させることができ、そのため配合時におけるゴム組成物の粘度上昇を抑えて、加工性を改善することができる。また、該無機充填剤の分散性を向上させることで十分なタイヤ性能を引き出すことができ、特に加工助剤として亜鉛を使用しないので加硫特性の低下を防ぐことができる。 According to the present invention, the above-mentioned specific fatty acid metal salt and fatty acid derivative are used in combination as a processing aid, so that a hydroxyl group-containing inorganic filler having a polarity higher than that of carbon black can be obtained using such a relatively polar functional group. The fatty acid metal salt and the fatty acid derivative possessed can be dispersed with an increased affinity, so that the increase in the viscosity of the rubber composition at the time of compounding can be suppressed and the processability can be improved. Further, by improving the dispersibility of the inorganic filler, it is possible to bring out sufficient tire performance. In particular, since zinc is not used as a processing aid, it is possible to prevent a decrease in vulcanization characteristics.

The Mooney viscosity of each rubber composition was measured. Each rubber composition was applied to a cap tread of a 185 / 70R14 test radial tire having a normal cap / base structure tread, and each tire was manufactured according to a conventional method to evaluate tire performance. The results are shown in Table 1. Measurement and evaluation methods are as follows.
・ムーニー粘度（ＭＬ１＋４）：ＪＩＳ Ｋ ６３００に準拠して１００℃での粘度を測定した。各データは、加工助剤を無添加の比較例１の値を１００として指数で示した。指数が小さいほど粘度が低いこと、即ち加工性が良好であることを示す。 Mooney viscosity (ML1 + 4): The viscosity at 100 ° C. was measured according to JIS K 6300. Each data is shown as an index with the value of Comparative Example 1 with no processing aid added being 100. A smaller index indicates a lower viscosity, that is, better workability.
・耐摩耗性：試験タイヤを規定リムを用いて、空気圧１８０ｋＰａに調整しタクシーに装着し、走行５，０００ｋｍ毎にローテーションを行い、２０，０００ｋｍ走行後の残溝深さからトレッドゴムの摩耗量を求め、耐摩耗性を評価した。比較例１を１００として指数表示し、数値が大きいほど良好である。 ・ Abrasion resistance: The test tire was adjusted to an air pressure of 180 kPa using a specified rim, mounted on a taxi, rotated every 5,000 km, and the amount of tread rubber wear from the remaining groove depth after 20,000 km. The wear resistance was evaluated. Comparative example 1 is shown as an index, and the larger the value, the better.
・ＲＲ性（燃費性能）：米国自動車技術者協会規格 ＳＡＥ Ｊ１２６９に準拠して測定し、評価した。比較例１を１００として指数表示し、数値が小さいほど良好である。 -RR property (fuel consumption performance): Measured and evaluated in accordance with American Automobile Engineers Association Standard SAE J1269. Comparative example 1 is shown as an index, and the smaller the value, the better.
・操縦安定性：試験タイヤを装着したテスト車を実車フィーリング試験担当ドライバーが運転して乾燥路面を走行したときの直進性及びレーンチェンジ性をフィーリングで判定し、比較例１のタイヤよりも優れるものを「５」、やや優れるものを「４」、同等のものを「３」、やや劣るものを「２」、劣るものを「１」の５点法で評価した。
表１に示すように、加工助剤として脂肪酸亜鉛を用いた比較例２では、加工性には優れるものの、補強性が劣っていた。また、他の従来の加工助剤である脂肪酸エステルやポリエチレングリコールなどを用いた比較例２〜６では、加工性の改善効果が不十分であり、加工性とタイヤ性能を高次元でバランスさせることのできないものであった。これに対し、実施例１〜６では、タイヤ性能を実質的に損なうことなく、ゴム組成物の粘度を低下させることで加工性が大幅に改善されており、よって、加工性とタイヤ性能を高次元でバランスさせることができるものであった。 As shown in Table 1, in Comparative Example 2 in which fatty acid zinc was used as a processing aid, the processability was excellent, but the reinforcement was inferior. Moreover, in Comparative Examples 2 to 6 using other conventional processing aids such as fatty acid esters and polyethylene glycol, the effect of improving the workability is insufficient, and the workability and the tire performance are balanced at a high level. It was not possible. On the other hand, in Examples 1 to 6, the workability is greatly improved by reducing the viscosity of the rubber composition without substantially impairing the tire performance, and thus the workability and the tire performance are improved. It could be balanced in dimension.
