GRINDING AND POLISHING COMPOSITION Russian patent published in 1994 - IPC

FIELD: powder metallurgy. SUBSTANCE: the composition comprises as a abrasive an ultradispersed diamond and graphite powder having 10-99 wt % diamond, an average diamond and graphite particle size of and a specific surface area of 380-390 m²/g. The composition comprises as a surface active polymer an amphateric sulfanilic acid-based iminofuran resin, the ratios of the components being as follows (wt % ): 1-30 ultradispersed diamond and graphite powder; 0.2-20 sulfanilic acid-based iminofuran resin and water, the balance. The composition components are mixed and thoroughly rubbed until the mixture becomes homogeneous, then diluted with water and stirred for 20-30 min. EFFECT: improved properties of the composition. 1 tbl
