ANTI-ADHESIVE TIRE, ANTI-ADHESIVE RUBBER AND METHOD OF THEIR MANUFACTURE AND APPLICATION Russian patent published in 2004 - IPC

FIELD: tire industry; manufacture of tires on tire-forming drums. SUBSTANCE: inflated tire is made from elastomer material; part of outer surface of this material is provided with anti-adhesive rubber containing mixture of natural rubber and chlorosulfonated polyethylene and possessing adequate hardening and anti-adhesive properties. Proposed method includes mixing natural rubber and chlorosulfonated polyethylene for molding anti-adhesive rubber; then first layer is molded and bonded to elastomer material, thus forming second layer of tire. Anti-adhesive rubber contains natural rubber, chlorosulfonated polyethylene, hardening agent, plasticizing agent and oxides of metals. Natural rubber and chlorosulfonated polyethylene are combined at addition of fillers, reinforcing agents, technological additives and plasticizing agents; then mixing agents, oxides of metals, hardening agents and hardening activators are mixed, thus molding anti-adhesive rubber for obtaining separate layer. Proposed method is used for turning the layers of cord around bead rings. EFFECT: avoidance of cracks at repeated use and lamination of anti-adhesive rubber from elastomer material. 15 cl, 3 dwg, 3 tbl
