Abstract

A multi-component system made from a thermoplastic component and a rubber component containing at least two different peroxide cross-linking agents with particular decomposition temperatures and a method for production of rubber and thermoplastic composite moulded pieces using the multicomponent system and the rubber and thermoplastic composite moulded pieces obtained thus.

Description

technical field [0001] The invention relates to a multi-component system (multi-component system) consisting of a thermoplastic component and a rubber component, wherein the rubber component comprises at least two different peroxide crosslinking agents with a specific decomposition temperature, and also It relates to a method for producing rubber-thermoplastic composite moldings using the multi-component system, and the resulting rubber-thermoplastic composite moldings. Background technique [0002] Due to the different temperature ranges in which the thermoplastic and rubber components are processed, the methods for producing rubber-plastic composites are often accompanied by difficulties related to the temperature distribution and dimensional stability of the thermoplastic and are difficult to achieve with a mold system and There are several problems with producing shaped articles of this type in a fully automated process. [0003] Adhesive bonding, screwing, riveting, or...
