<p>A method for removing a defect of the surface greying of all-rubber cemented shoes which are pressure-vulcanised, in the hot air, is processed by mixing an antioxidant agent, which is combined with a substance proving wax properties, into a rubber mixture. 100 weight parts of pure rubber are added with 0.5 to 2 weight parts of polymerised 2,2,4-trimethyl-1,2- -dihydrochinoline and 1 - 5 weight parts of the substance proving wax properties having a softening temperature in a range from 63 to 67 degrees Celsius and measuring weight of 0.92 g/cm3.</p> |
