METHOD FOR MANUFACTURING A MOULDED ARTICLE WITH INSERT FROM A RUBBER POLYMER

摘要

The invention relates to a method for manufacturing a moulded article from a first rubber polymer, which moulded article comprises an insert from a second rubber polymer. The method comprises at least the steps of providing a vulcanizing mould with mounting means for the insert, arranging an at least partially vulcanized insert in the vulcanizing mould using the mounting means, adding the first rubber polymer to the vulcanizing mould in unvulcanized state and vulcanizing the moulded article at a suitable vulcanization temperature and subsequently removing the moulded article, with the proviso that prior to step C) at least that side of the insert which comes into contact with the first rubber polymer during step C) is provided with a reactive mixture comprising free radicals. The method is particularly suitable for the manufacture of rubber tyres and spoilers with a coloured insert.
