Method for mutually adhering moulded articles of vulcanized rubber

Abstract

The invention relates to a method for mutually adhering moulded 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 moulded 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.

1 . Assembly of mutually adhered moulded articles of substantially vulcanized rubber polymers, which assembly comprises an adhesive layer of a rubber composition which comprises a peroxide with an initiating temperature lower than the vulcanization temperature of the rubber polymers, the assembly manufactured in accordance with the method of  claim 1 . 
     
     
         2 . Assembly as claimed in  claim 1 , wherein the adhesive layer has an average thickness of 0.05 to 0.5 mm. 
     
     
         3 . Assembly as claimed in  claim 2 , wherein the adhesive layer has an average thickness of 0.1 to 0.3 mm. 
     
     
         4 . Assembly as claimed in  claim 1 , wherein it also comprises a film which is at least partially anchored between the moulded articles. 
     
     
         5 . Assembly as claimed in  claim 1 , the assembly comprising a flexible spoiler for a vehicle, comprising an airflow-conducting element of a first rubber polymer, a mounting member of a second rubber polymer for mounting the spoiler to the vehicle and an operating member which can move the airflow-conducting element in and out, wherein the operating member takes the form of a number of inflatable bellows of plastic film disposed on the rear side of the spoiler, wherein the operating member, the airflow-conducting element and the mounting member are mutually connected.
