Abstract
The invention relates to a method for mutually adhering molded articles of at least partially vulcanized rubber polymers. The method comprises at least the steps of providing a rubber composition which comprises a peroxide with an initiating temperature lower than the vulcanization temperature of at least one of the rubber polymers; arranging an adhesive layer of the rubber composition on the surface of the molded articles which is to be adhered; bringing the surfaces for adhering together under pressure; and vulcanizing at least the adhesive layer at an increased temperature.
Claims13
Method for mutually adhering moulded articles of at least partially vulcanized rubber polymers, which method comprises at least the following steps of
- (A) providing a rubber composition which comprises a peroxide with an initiating temperature lower than the vulcanization temperature of the rubber polymers;
- (B) arranging an adhesive layer of the rubber composition on the surface of the moulded articles which are to be adhered;
- (C) bringing the surfaces for adhering together under pressure;
- and
- (D) vulcanizing the rubber composition of the adhesive layer at an increased temperature, with the proviso that the rubber composition is vulcanized at the position of the surfaces for adhering at a maximum set temperature that is lower than the vulcanization temperature of the rubber polymers,
- wherein the method comprises the following additional steps of:
- (E) providing a film;
- (F) arranging at least part of the film between the two surfaces prior to step (C),
- with the proviso that the temperature in step (D) is lower than the melting or degradation temperature of the film,
- and wherein the film constitutes one or more inflatable bellows of plastic film.
