METHOD OF MANUFACTURE, MOLDING AND VULCANIZATION OF TIRES FOR WHEELS OF VEHICLES Russian patent published in 2004 - IPC

FIELD: chemical industry.

SUBSTANCE: the invention offers two methods dealt with chemical industry and used for manufacture, molding and vulcanization of tires for wheels of vehicles. According to the first alternative of realization of the method, before a stage of feeding of a fluid medium under pressure they additionally conduct a stage of treatment of the internal surface of the non-vulcanized tire, that prevents permeation of the fluid medium under pressure inside a tire itself. The indicated treatment includes a joint of at least one layer of previously vulcanized elastomeric material with an inside surface of a non-vulcanized tire, which molding is conducted by application on the outer surface of a toroidal foundation of the undercoat containing a polymer base and a vulcanizing system in the for of a water emulsion. According to the second alternative of realization of the method the additional treatment also includes a joining of a layer of the previously vulcanized elastomeric material with an inner surface of the non-vulcanized tire, molding of which is conducted by application on the outer surface of a toroidal foundation of the undercoat. At that they conduct a stage of a vulcanization of the undercoat, when the layer of the previously vulcanized elastomeric material is making a contact with the sulfur-containing vulcanized mixture. The given method ensures prevention of permeation of the fluid medium under pressure inside the tire itself.

EFFECT: the invention ensures prevention of permeation of the fluid medium under pressure inside the tire itself.
