FIELD: rubber industry; interconnection of rubbers on the basis of noncovulcanizable unsaturated general-purpose and saturated caoutchoucs. SUBSTANCE: rubber on the basis of unsaturated general-purpose caoutchoucs is preliminarily vulcanized, rough and covered with glue which is then dried. Then rubber, thus treated, is connected with second layer of nonvulcanized rubber on saturated caoutchouc base, and both layers are vulcanized together. Preliminary vulcanization of rubber on unsaturated caoutchouc base provides equalizing of degree of unsaturation of connected rubbers. Proposed method can be used for fastening heel of valve made of rubber on the basis of unsaturated general-purpose caoutchouc to body of chamber made of butyl rubber. EFFECT: improved quality of connection of rubber layers. 1 cl
