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 molding (2K injection molding), from at least one part composed of at least one polyamide molding 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 comprising at least one polyamide moulding composition, directly adhered with at least one part comprising at least one elastomer, wherein:
- the polyamide moulding composition comprises a mixture of polyamide and at least one polybutadiene copolymer which is liquid at room temperature (RT);
- and
- the elastomer comprises a rubber which is crosslinkable or vulcanizable with elemental sulphur.
A method of boosting composite adhesion between components of a composite part, the components comprising at least one part comprising a polyamide moulding composition, and at least one part comprising are elastomer obtained from rubber crosslinkable or vulcanizable with elemental sulphur, the method comprising mixing at least one polybutadiene copolymer which is liquid at room temperature (RT) with the polyamide moulding composition.
A method for producing composite parts which are composed of at least one part comprising at least one polyamide moulding composition, and at least one part comprising at least one elastomer comprising a rubber vulcanizable or crosslinkable with elemental sulphur as crosslinking agent, the method comprising:
- either, contacting the at least one part comprising the at least one polyamide moulding composition with at least one rubber comprising elemental sulphur to form a composite, and subjecting the composite to vulcanization conditions for the rubber,
- or, contacting the at least one part comprising rubber with at least one polyamide moulding composition to form a composite, and subjecting the composite to vulcanization conditions for the rubber,
- wherein the polyamide moulding composition comprises a mixture of polyamide with at least one polybutadiene copolymer which is liquid at room temperature (RT).
