    Rubber is recovered for re-use e.g. from scrap pneumatic tires by briefly raising a surface of the tire to a high temperature and then rasping the heat-treated surface. Tires reinforced either with a textile or a steel ply can first be parted on opposite sides of the breaker structure. A machine is provided which accepts pieces of vulcanized material and progressively reduces them to heat-treated particles by repetitively heating a surface of each piece and attacking it with a rasping tool.

    SU433165A1|1974-06-25|METHOD OF REGENERATION OF RUBBER1 This invention relates to methods for regenerating rubber based on butyl rubber, vulcanized with resins, using activators. Methods are known to regenerate vulcanized butyl rubber using activators, for example, alkylphenol disulfide, halogen-containing patterns, and body patterns and aromatics and aromatics with the use of activators; as well as improving the quality of the regenerate, it is proposed to use as an activator in the regeneration of butyl rubber, vulcanized with resins, diphenylguanium Din. The method consists in the following. To 100 weight. Part of waste or rejected rubber based on butyl rubber, vulcanized with resins, previously crushed on the crushing rollers, add 2-4 weight. including activator of destruction - diphenylguanidine known method. The mixture is heated in an air or vapor-air environment at a temperature of 160-180 ° C for 2-3 hours. After heating, the devulcanized product is subjected to additional mechanical treatment to homogenize and purify the impurities and part of the slightly devulcanised rubber. Example. The butyl rubber rubber diaphragm used in the vulcanization of tires is cut into pieces and passed through rollers with a grooved roll surface. The resulting sheet is placed in a laboratory autoclave, where it is kept at 180 ° C for 2 hours. After heating, the devulcanate is processed on smooth rollers until an even gloss is obtained. The properties of the floor epnogo regenerator to regenerate in comparison with the known method shown in tablitse.15
