PURPOSE:To prolong polishing time by compounding a synthetic resin with specified amts. of an abrasive and a compd. mainly comprising a surfactant. CONSTITUTION:A compd. is prepd. by mixing a surfactant (e.g. a fatty acid salt), the main component, with an anticorrosive agent (e.g. a phosphate) and at least one chelating agent (e.g. an aminopolycarboxylic acid) or cleaning aid (e.g. carboxymethylcellulose). A barrel polishing stone is obtd. by homogeneously mixing about 20-90wt.% synthetic resin (e.g. a polyester resin) with about 10-80wt.% abrasive (e.g. alundum) and about 0.1-10wt.% compd. above-prepd., further mixing with a curative, thermally curing the mixture in a mold with a desired shape. and demolding the resulting product. |
