Abstract
The invention relates to a composite part, hereinafter also referred to as composite, which is produced by means of 2-component processing methods, preferably 2-component injection moulding (2K injection moulding), from at least one part composed of at least one polyamide moulding composition additized with polybutadiene copolymer which is livid at room temperature and at least one part composed of at least one elastomer obtainable from rubber that is to be vulcanized or crosslinked with elemental sulphur, or is composed of these components after processing thereof.
Claims17
A composite part comprising at least one part produced from at least one polyamide moulding composition, and at least one part produced from at least one elastomer, wherein:
- the polyamide moulding composition comprises a mixture of polyamide having at least one polybutadiene copolymer which is liquid at room temperature (RT);
- and
- the elastomer part comprises a rubber which is to be crosslinked or vulcanized with elemental sulphur.
A method of boosting composite adhesion of a composite part comprising at least one part produced from a polyamide moulding composition and at least one part produced from an elastomers obtained from rubber to be crosslinked or to be vulcanized with elemental sulphur, and obtained by means of at least one shaping process, the method comprising including at least one polybutadiene copolymer which is liquid at room temperature (RT) in the polyamide moulding composition.
A method for producing composite parts which are composed of at least one part produced from at least one polyamide moulding composition, and at least one part produced from at least one elastomer obtained from rubber that is to be vulcanized or crosslinked with elemental sulphur as crosslinking agent, the method comprising by at least one shaping method;
- either, contacting the part composed of the polyamide moulding composition is with a rubber component comprising elemental sulphur to form a composite, and subjecting the composite to vulcanization conditions for the rubber,
- or, contacting the part composed of elemental sulphur-crosslinked rubber with the polyamide moulding composition to form a composite, and subjection the composite to vulcanization conditions for the rubber,
- wherein the polyamide moulding composition contains a mixture of polyamide with at least one polybutadiene copolymer which is liquid at room temperature (RT).
