したゴム配合が適用されていた。[Prior Art] In recent years, rubber chains have been attracting attention as tire anti-slip devices instead of metal chains, which cause dust pollution. Rubber compounds for rubber chains have been considered based on tire tread rubber compounds, which have already been proven in the past, because of the purpose of use, which is to attach them to tires. In other words, the rubber for conventional rubber chains has
Conventional tread rubber formulations, mainly consisting of natural rubber with excellent mechanical properties and cold resistance, or slightly modified versions of this rubber formulation have been used.

た。[Problems to be Solved by the Invention] However, when a conventional rubber chain with a tread rubber composition or a rubber composition similar to a tread rubber composition is attached to a tire and driven for a long time, the tire surface and The back side of the rubber chain will stick, making it extremely difficult to remove. In particular, if the rubber chain is left as it is for a long time after running for a long time, it may not be possible to remove the rubber chain without using a tool, which has the disadvantage that it takes time and effort to remove the rubber chain after running.

明を完成させた。That is, the inventor of the present invention conducted extensive research to prevent sticking to tires, which is a drawback of conventional rubber chains.
The tire and the rubber chain attached to it do not rotate at the same time during driving, and are slightly misaligned.The shearing force and heat generated by this misalignment cause the natural rubber in the rubber compound to selectively cover the surface, making it extremely sticky. It has been clarified that the change to a substance with a high carbon content is the cause of the above-mentioned adhesion. and styrene butadiene rubber (SBR) 90 to 40]i parts,
By using a rubber with the remainder being butadiene rubber (BR), a rubber that does not become sticky even after long-term use can be obtained.
They discovered that the problem of adhesion with tires could be solved and completed the present invention.

５０部とりわけ８０〜６０部とするのが好適である。In the rubber composition constituting the tire slipper of the present invention,
When the amount of SBR is less than 40 parts and the amount of BR exceeds 60 parts, the wear resistance of the tire skid improves, but the cut resistance decreases. In the present invention, the SBR is particularly from 70 to
It is preferably 50 parts, particularly 80 to 60 parts.

場合に得られる硬度である。The tire anti-slip device of the present invention has a hardness (JISA hardness) of 50 to 75 degrees. If the hardness is less than 50", sufficient durability and abrasion resistance cannot be obtained, and if the hardness exceeds 75°, problems will arise in the anti-slip performance on ice and snow.
The hardness of 0 to 75° rubber is also obtained when carbon black is blended into the rubber composition in order to ensure the mechanical strength of the rubber.

ある場合において、著しく優れた効果が得られる。As is clear from Table 1, when the BR content of SBR/BR is increased (Comparative Example 1), both the adhesive strength and the abrasion resistance improve, but the cud resistance decreases. On the other hand, when natural rubber is blended (Comparative Example 2), physical properties such as hardness, abrasion resistance, and cut resistance are sufficiently improved, but on the other hand, there is a drawback that adhesive strength is significantly high, which is an improvement point of the present invention. . On the other hand, the rubber according to the present invention in Example 1.2 has excellent physical properties and adhesive strength, and is suitable for tire anti-slip devices. Particularly, in the present invention, when the rubber component is 80 to 60 parts of 5BR and the balance is BR, extremely excellent effects can be obtained.
