The abrasion-resistant rubber of the present invention is a synthetic resin excellent in abrasion resistance, in which the compounding amount of carbon black having a high structure is reduced to 10 to 30 parts by weight as compared with the conventional 40 to 70 parts by weight. Since 40 to 60 parts by weight of powder is blended, the above rubber, carbon black, synthetic resin powder, vulcanizing agent, vulcanizing aid, plasticizer and the like are intermixed,
When kneaded with a Banbury mixer or rolls, it is uniformly and easily dispersed, so that the calorific value is small and premature vulcanization does not occur. And, since the lubricating hard coating film is provided on the surface where the above synthetic resin powder is exposed by the surface polishing after being molded into a desired shape and vulcanized, the sliding is good and the vulcanized rubber is worn. The amount is significantly smaller than before, and even if the lubricious hard coating wears due to use,
The abrasion resistant synthetic resin powder in the rubber is gradually exposed on the surface,
Since this synthetic resin powder is in contact with other machine parts, the slidability is maintained well and the progress of wear is suppressed.

However, if the amount of the carbon black compounded is less than 10 parts by weight, the desired physical properties cannot be obtained, and if it exceeds 30 parts by weight, the workability during kneading deteriorates. Further, if the blending amount of the above synthetic resin powder is less than 40 parts by weight, abrasion resistance is insufficient, and conversely, if it exceeds 60 parts by weight, workability during kneading decreases. Further, when the thickness of the lubricious hard coating film is less than 3 μm, the effect of coating is not obtained, and
If it exceeds μm, the workability of coating is deteriorated.
