Abstract:
This invention relates to an anti-friction bearing lining composition which comprises the product resulting from heating at a sufficient temperature and for a sufficient period of time to cause curing a mixture of: A. AT LEAST ONE SOLID EPOXY RESIN CONTAINING TERMINAL EPOXY GROUPS AND HAVING A MOLECULAR WEIGHT IN THE RANGE FROM ABOUT 2,000 TO 4,000; B. A CARBOXYLIC ACID ANHYDRIDE IN AN AMOUNT FROM ABOUT 1 TO 17 EQUIVALENTS OF ANHYDRIDE PER EPOXY EQUIVALENT; C. AN ORGANIC CURING ACCELERATOR CONTAINING AN ACTIVE HYDROGEN ATOM OR A TERTIARY AMINE GROUP IN AN AMOUNT FROM ABOUT 0.1 TO 0.5 PHR (PARTS PER 100 PARTS RESIN); AND D. ONE OR MORE INORGANIC ANTI-FRICTION MATERIALS IN AN AMOUNT FROM ABOUT 4 TO 20 PERCENT BY WEIGHT.
Abstract:
This invention relates to an organometallic reticulated antifriction composition comprising at least one solid epoxy resin containing terminal epoxy groups and a molecular weight in the range from about 2,000 to 4,000 having incorporated therein from about 5 to 60 percent by weight of lead and/or bismuth powder or powdered alloys containing lead and/or bismuth, said reticulation having been caused by heating the composition for a sufficient period of time and at a sufficient temperature to effect said reticulation. This invention also relates to metal bearings coated with said organo-metallic anti-friction compositions and their method of manufacture.
