Abstract

An abrasive article comprises abrasive grains and a bonding material comprising a thermoset binder resin and at least one filler in the form of a mixture of at least one alkali metal salt of sulphuric, hydrochloric or hydrobromic acid with at least one metallic sulphide in the form of a sulphide of antimony, iron, lead or zinc, said filler being present in a proportion of at least 2%, based on the volume of said bonding material. The specified binders are "B"-stage phenol-aldehyde and cresol-aldehyde resins. Specified abrasives are silicon carbide, boron carbide, tantalum carbide, tungsten carbide, alumina, diamond grains, glass, quatrz and garnet. The compositions may also contain cross-linking and curing agents, e.g. paraformaldehyde and hexamethylene tetramine, modifying resins, e.g. epoxy resins, vinyl chloride and vinyl butyral resins, styrene-acrylonitrile resins and butadiene-acrylonitrile rubbers, solvents or plasticizers, e.g. furfuraldehyde, propylene sulphite, furfuryl alcohol and cresol and fillers, e.g. cryolite, felspar and iron oxide. In the examples, abrasive wheels are made by cold pressing a mixture of a powdered "B" stage phenolformaldehyde resin, lime, an abrasive, furfuraldehyde, tar oil and (I) and (II) mixtures of potassium sulphate and zinc sulphide, (III) mixtures of (a) potassium bromide and zinc sulphide, (b) potassium chloride and zinc sulphide, (c) potassium sulphate and antimony sulphide, (d) potassium sulphate and lead sulphide, and (e) potassium sulphate and ferrous sulphide. U.S.A. Specification 2,860,961 is referred to.
