【発明の詳細な説明】
〔産業上の利用分野〕
本発明は、氷上摩擦性能を向上させたゴム組成物に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a rubber composition with improved friction performance on ice.
凍結した路面、特に氷と水とが混在するような0℃付近
の路面は、滑り易く、歩行や自動車の走行が危険である
。Frozen road surfaces, especially roads at temperatures around 0° C. where ice and water coexist, are slippery and dangerous for walking or driving.
そこで、従来、このような路面での安全な走行を可能と
するために、例えば、タイヤのトレッド部を低温でも軟
質のゴム材料で構成したり、発泡ゴム材料で構成したり
している。しかしながら、この場合、耐摩耗性に劣ると
いう問題がある。Conventionally, in order to enable safe driving on such road surfaces, tire treads have been made of, for example, a rubber material that is soft even at low temperatures, or a foamed rubber material. However, in this case, there is a problem that the wear resistance is poor.
本発明は、このような事情にかんがみなされたものであ
って、耐摩耗性を実質的に損なうことなしに氷上摩擦性
能を向上させたゴム組成物を提供することを目的とする
。The present invention was conceived in view of these circumstances, and an object of the present invention is to provide a rubber composition that has improved friction performance on ice without substantially impairing wear resistance.
本発明のゴム組成物は、水溶性無機化合物を含有してお
り、その粒子同士が実質的に互いに接触していないこと
を特徴とする。The rubber composition of the present invention contains a water-soluble inorganic compound, and is characterized in that its particles are not substantially in contact with each other.
このように本発明では、粒子同士が実質的に互いに接触
していない状態で水溶性無機化合物を含有するため、本
発明のゴム組成物で例えばタイヤのトレッド部を構成し
た場合、凍結した路面の走行時にトレンド表面の水溶性
無機化合物が路面の水に溶は出してトレンド表面に凹凸
が形成されるので、氷上摩擦性能を高めることができる
。また、トレッド部の内部の水溶性無機化合物は溶は出
さないのでトレッド部が発泡状態とはならないから、耐
摩耗性が実質的に損なわれることはない。In this way, in the present invention, since the particles contain a water-soluble inorganic compound in a state in which they are not substantially in contact with each other, when the rubber composition of the present invention is used to form, for example, the tread portion of a tire, it can be used on frozen road surfaces. When driving, the water-soluble inorganic compounds on the trend surface dissolve into the water on the road surface, forming irregularities on the trend surface, which can improve friction performance on ice. Further, since the water-soluble inorganic compound inside the tread portion does not dissolve, the tread portion does not become foamed, so that wear resistance is not substantially impaired.
以下、上記手段につき詳しく説明する。The above means will be explained in detail below.
本発明で用いる水溶性無機化合物は、“0℃の飽和溶液
100g中に1g以上存在する”という0℃における水
への溶解度を有するものである。この水溶性無機化合物
としては、例えば、塩化カリウム、塩化カルシウム、塩
化鉄、塩化ナトリウム、塩化バリウム、塩化マグネシウ
ムなどの金属塩化物:硝酸カリウム、硝酸ナトリウム等
の硝酸化物:炭酸カリウム、炭酸ナトリウム等の炭酸化
合物;硫酸亜鉛、硫酸銅、硫酸合歓等の硫酸化合物が挙
げられる。これらのうち、塩化ナトリウム、特に塩化ナ
トリウムを主成分とする食塩を用いるのが好ましい。食
塩は、人手し易く、安価だからである。The water-soluble inorganic compound used in the present invention has a solubility in water at 0°C such that 1g or more is present in 100g of a saturated solution at 0°C. These water-soluble inorganic compounds include, for example, metal chlorides such as potassium chloride, calcium chloride, iron chloride, sodium chloride, barium chloride, and magnesium chloride; nitrates such as potassium nitrate and sodium nitrate; and carbonates such as potassium carbonate and sodium carbonate. Compounds: Examples include sulfuric acid compounds such as zinc sulfate, copper sulfate, and sulfuric acid. Among these, it is preferable to use sodium chloride, particularly common salt containing sodium chloride as a main component. This is because table salt is easy to produce and inexpensive.

ある。The rubber composition of the present invention contains this water-soluble inorganic compound. Particles of this water-soluble inorganic compound are not substantially in contact with each other within the rubber composition. That is, the individual particles of the water-soluble inorganic compound are substantially independently dispersed within the rubber composition. If the particles are not dispersed in this way, that is, if the particles are in contact with each other, the rubber composition will form the trend part of the tire, and when the tire is driven on an icy road surface, the inside of the tread part will be damaged. This is because even the water-soluble inorganic compounds in the tread are leached out, forming communicating pores from the tread surface to the inside, and the tread becomes foamed to the inside, impairing wear resistance.
水溶性無機化合物の個々の粒子を実質的に独立に分散さ
せるには、水溶性無機化合物の粒径および配合量を適宜
勘案して水溶性無機化合物をゴム組成物に配合し、混練
を行えばよい。すなわち、粒径が大きいときには配合量
を少なくし、一方、粒径が小さいときには配合量を多く
するなどすればよい。水溶性無機化合物の平均粒径は、
5〜2000μ−程度である。In order to substantially independently disperse individual particles of a water-soluble inorganic compound, the water-soluble inorganic compound is blended into a rubber composition, taking into consideration the particle size and blending amount of the water-soluble inorganic compound, and kneaded. good. That is, when the particle size is large, the amount to be blended may be reduced, while when the particle size is small, the amount to be blended may be increased. The average particle size of water-soluble inorganic compounds is
It is about 5 to 2000μ.
