METHODS FOR TREATING RUBBER-CONTAINING PARTICLES AND PRODUCTS PRODUCED THEREFROM

摘要

Methods for treating rubber-containing particles to produce materials suitable for blending with thermoplastic or thermoset polymers are disclosed. The rubber-containing particles are mixed with a fatty acid-containing material in a friction mixer to produce a rubber-containing particulate mixture. The rubber-containing particles may comprise virgin or recycled particulate rubber such as from used tires.

1. A method of treating rubber-containing particles comprising:
mixing rubber-containing particles and at least one fatty acid-containing material in a friction mixer to thereby generate sufficient heat to raise the temperature of the mixture to at least 200° F. and to produce a rubber-containing particulate mixture, wherein the temperature is raised without application of an external heat source to the rubber-containing particles or the fatty acid-containing material.
