Abstract
Recycled rubber is cold vulcanized at reactive sites in recycled rubber that were not reacted during initial production of articles such as tires from rubber. The provides for improved coating compositions having good tensile strength and cure times Such cold vulcanization of recycled rubber is effected by use of reactive metal oxides which the oxidation number of the metal is one that is other than its most stable state and include cuprous oxide, manganese dioxide and hausmannite (Mn3O4). Less reactive oxides such as iron oxides, silicon oxides, aluminum oxides chromium oxide and titanium dioxide are less effective.
Claims14
A coating composition optionally comprising water wherein the composition excluding any water present comprises as percentages by weight a mixture of 10-60% recycled rubber particles, 0-40% glass or plastic particles, 0-10% graphite and/or fluorinated resin, and from 10-50% of a film forming resin, and from 4-10% of a reactive metal oxide.
