METAL-POLYMERIC COMPOSITION FOR MANUFACTURING CAST IRON BARS Russian patent published in 2008 - IPC C08L61/10 C08K3/08 

FIELD: chemistry.

SUBSTANCE: invention relates to powder metallurgy, namely to metal-polymeric compositions for obtaining cast iron bars. Metal-polymeric composition is obtained by mechanical mixing of two mixtures - as component of the first high-dispersion powders of iron and, probably, at least, one alloying element is used, as components of the second - thermo-reactive phenol-formaldehyde resin, plastificator and iron oxide powder are used, as plastificator salt of stearine acid is used, with the following ratio of components mass %: - thermoreactive phenolformaldehyde resin -15-20; -salt of stearine acid -0.4-1.5; -iron oxide (III) -0.2-32; -iron powder - the remaining part. As alloying element in the first mixture high-dispersion powder of nickel, chrome, copper, molybdenum, manganese, aliminium, titanium, vanadium, silicon is used.

EFFECT: reduction of technological cycle of manufacturing of cast iron products and expanding their range.
