<p>A rubber composition comprising (1) 100 parts by weight of at least one organic rubber selected from natural rubber and organic synthetic rubbers or 100 parts by weight of a rubber mixture of 98 to 80% by weight of said organic rubber and 2 to 20% by weight of a silicone raw rubber having a molecular weight of 100,000 to 1,000,000 and (2) 0.5 to 50 parts by weight of at least one hon-tackiness-imparting agent selected from (a) fatty acid amides, (b) fatty acid glycerides and (c) polyhydric alcohols, polyhydric thioalcohols and monoalkyl ethers thereof represented by the general formula (HX)n-R-XR' where X is an oxygen or a sulfur atom, R is an alkylene group which may contain an ether or a thioether linkage, R ' is a hydrogen atom or an alkyl group of 1 to 12 carbon atoms and n is an integer of 1 or 2. The vulcanizate of said rubber composition is non-tacky and suitable for use as a surface layer of conveyor belts for carrying highly tacky substances such as oil sand.</p> |
