〔産業上の利用分野 〕
本発明はタイヤや靴底等に利用できる加硫ゴム組成物に
関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vulcanized rubber composition that can be used for tires, shoe soles, etc.
従来、氷雪面等での滑り防止のため、タイヤや靴底に使
用するゴムの改良や構成に種々の工夫がなされている。Conventionally, in order to prevent slipping on icy and snowy surfaces, various improvements and constructions have been made to the rubber used for tires and shoe soles.
そして、工夫されたものとして、金属製のスパイクを装
着したものや、ゴムの組成を低温下でも柔軟に保持でき
るものとし、氷雪面との摩擦抵抗を大きくするようにし
たものがある。Some innovations include those that are equipped with metal spikes, and those that have a rubber composition that allows them to remain flexible even at low temperatures, increasing the frictional resistance against ice and snow surfaces.
ゴムの組成を低温下でも柔軟にするためには、未加硫ゴ
ム組成物に補強剤や充填剤をできる限り少量に止めてガ
ラス転移点の低温下を図っている。In order to make the rubber composition flexible even at low temperatures, the amount of reinforcing agents and fillers in the unvulcanized rubber composition is kept as small as possible in order to keep the rubber composition below the glass transition point.
一般にゴムが氷雪面等で良く滑る理由は、氷雪面とこす
り合う時に生じる圧力融解と摩擦熱によって形成される
水腹、及びこの水腹が熱伝導率の不良体によるエネルギ
ーの蓄積で速く形成されることによる。In general, the reason why rubber slips well on ice and snow surfaces is that a water belly is formed due to pressure melting and frictional heat that occurs when it rubs against the ice and snow surface, and this water belly is quickly formed due to the accumulation of energy due to materials with poor thermal conductivity. Depends on the situation.
このことは、１８９８年、Ｎａｎ５ｅｎが低温時、熱の
良導体の摩擦抵抗は不良導体摩擦よりかなり大きいこと
を発見し、次いで、１９４７年、Ｋｌｅｉｎが航空機の
氷雪上でのスキーの滑り特性について広範囲に行った実
験により証明されている。This is because in 1898, Nanben discovered that at low temperatures, the frictional resistance of a good conductor of heat was considerably greater than that of a poor conductor, and then in 1947, Klein extensively studied the sliding characteristics of aircraft skis on ice and snow. Proven by experiments conducted.
例えば、スキー板滑走面にコーティングされるワックス
類は、ゴム加硫物と共に代表的な熱の不良導体であり、
このことはゴム加硫物が氷雪上では非常に滑り易い物質
であることを示し、又スキーやスケートに於ける摩擦抵
抗値の著しい低い状Ｂ（μ＝０．０３）は、スキーやス
ケートの表面と氷雪面との圧力融解によって生じる水腹
層のため潤滑されるためである。For example, waxes coated on the sliding surface of skis, along with rubber vulcanizates, are typical poor conductors of heat.
This shows that the rubber vulcanizate is a very slippery substance on ice and snow, and the extremely low frictional resistance value B (μ = 0.03) in skis and skates means that the rubber vulcanizate is a very slippery substance on ice and snow. This is because the water layer created by pressure melting between the surface and the ice and snow provides lubrication.
更に、この時の二つの滑り面に生じる摩擦エネルギーに
よる氷雪面が表面融解されて形成される水腹層、及び材
質の異なる熱伝導率の差異によって、滑り抵抗が影響を
受けるのである。Furthermore, the sliding resistance is affected by the water layer formed by the surface melting of the ice and snow surface due to the frictional energy generated between the two sliding surfaces at this time, and by the difference in thermal conductivity of different materials.
そして、固体の材質と氷上を滑る摩擦に対して、温度が
いかに影響を与えるかについては、次の表に示す通り、
摩擦は温度が下がるにつれて著しく増大し、低い熱伝導
を持つ固体はど摩擦は低くなっている。The following table shows how temperature affects the friction of sliding on solid materials and ice.
Friction increases significantly as temperature decreases, and solids with low heat conductivity have lower friction.

成るものである。[Means for Solving the Problems] The vulcanized rubber composition of the present invention is made by plasticizing polynorbornene with an aromatic oil to form an improved polymer with a secondary transition point adjusted to a range of 0°C ± 5°C. , metal oxide fine particles are blended in a ratio of 50 parts or more to 100 parts of polynorbornene.
ポリノルボーネンはシクロペンタジェンにエチレンを加
え、ディールスアダルダ反応でノルボーネンを得、更に
開環重合して得られる。Polynorbornene is obtained by adding ethylene to cyclopentadiene, performing a Diels-Adalda reaction to obtain norbornene, and then performing ring-opening polymerization.

移点を０００に調整することができる。When a petroleum softener (specific gravity 0.96 to 1.02, pour point 00C or higher, aromatic hydrocarbon content 35% or higher) is added as a plasticizer to 100 parts of this polynorbornene,
As the amount added increases, the second-order transition point decreases, and the second-order transition point can be adjusted to 000.

て作用する。The vulcanized rubber composition of the present invention hardens at subzero temperatures, so if it is molded with a design-like uneven surface, the raised portions will bite into the ice and snow surface and act as a friction resistor, while at room temperature it acts as a soft rubber resistor. .
又、熱伝導率の良導体である金属微粒子は、発生したエ

に近い作用となる。In addition, fine metal particles, which are good conductors of thermal conductivity, quickly conduct the generated energy and dissipate heat, so energy is not accumulated and acts to prevent the formation of a water film. In this composition containing a large amount of metal particles, the metal grains are in contact with each other and are dispersed, so that heat absorption, heat radiation, and transfer effects occur rapidly, resulting in effects close to those of metal.
更に、多量に金属酸化物微粒子を配合した加硫ゴム組成
物も当然こすり合う面では摩耗を生ずることとなる。Furthermore, a vulcanized rubber composition containing a large amount of metal oxide fine particles naturally causes wear on surfaces that rub against each other.
けれども、この摩耗により発生する金属酸化物の含有し

作用し、摩擦抵抗を大きくするのである。However, the fine rubber powder containing metal oxides generated by this wear acts as a polishing material equivalent to the valve plates, aluminum, and abrasive grains used when polishing lenses and glass, increasing frictional resistance. be.
以上の様に本発明は、常温時では通常の軟質ゴムである

鋭角的な形状はスパイクとして作用するため、氷雪面と
の摩擦抵抗を増大せしめる効果を有する。As described above, the present invention is made of ordinary soft rubber at room temperature, but the rubber that is vulcanized and molded at sub-zero temperatures hardens, and its acute angular shape acts as a spike, causing friction with the ice and snow surface. It has the effect of increasing resistance.
そして、多量に配合した金属酸化物微粒子は、氷雪面と
こすり合う時に生じる熱を良好な熱伝導作用により吸収
・放熱・伝達を敏速に行うため、エネルギーの蓄積を防
止し、潤滑剤となる水膜の形成を阻止する効果を有する
。In addition, the large amount of metal oxide fine particles blended with the ice and snow surface quickly absorbs, radiates, and transfers the heat generated when they rub against the ice and snow surface. It has the effect of inhibiting film formation.
更に、ａｍによって発生したゴム微粉末がボリシ材とし

ボリシング効果を発揮し滑りを防止するのである。この
ボリシング効果は、濡れた路面、床材にも有効である。Furthermore, the fine rubber powder generated by am acts as a borishing material, and when the fine rubber powder is buried in the uneven surface of ice and snow and its particle size is larger than the water layer, the frictional resistance is affected by the lubricating effect of the water layer. On the other hand, on the worn rubber surface, there are also metal oxide fine particles exposed on the surface, which synergistically exerts a bollifying effect and prevents slipping. This borishing effect is also effective on wet road surfaces and floor materials.
従って、本発明はタイヤや靴或は階段等応用範囲の広い
ゴム組成物であり、特にタイヤや靴では状況に応じて脱
着の必要のない全天候型の加硫ゴム組成物となる。Therefore, the present invention is a rubber composition that has a wide range of applications such as tires, shoes, and stairs, and particularly for tires and shoes, it is an all-weather vulcanized rubber composition that does not require attachment or detachment depending on the situation.
