Method and system for treating elastomers and articles made therefrom

摘要

A method and system for treating rubber-containing elastomers to produce materials suitable for blending with thermoplastic or thermoset polymers are disclosed. The elastomers may comprise virgin or recycled particulate rubber such as from used tires. The blended rubber and polymer materials possess thermoplastic properties and can be reused many times.

1. A method of making composite materials comprising:
mixing elastomeric particles comprising rubber and at least one fatty acid-containing material in a friction mixer to thereby generate sufficient heat to raise the temperature of the rubber-containing particulate mixture to a selected mixing temperature to thereby produce rubber/fatty acid particles; cooling the rubber/fatty acid particles; and blending the rubber/fatty acid particles with particles of at least one thermoplastic or thermoset polymer to form a composite material comprising the rubber and polymer.
