METHOD OF PRODUCING METAL-MODIFIED FILLER FOR RUBBER Russian patent published in 2016 - IPC C08K3/04 C08K3/36 B82B3/00 C08K9/02 C08L21/00 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to production of elastomeric composite materials. Method comprises preparation of saturated aqueous solution of metal formate with addition of filler. Metal is selected from copper, nickel or cobalt. Filler is selected from aerosil, colloidal silicic acid or technical carbon. For adsorption of metal formate on filler suspension with periodic stirring is held for 72 hours at 25 °C. Solution is filtered, precipitate is dried for 3 hours at temperature of 70 °C and ground. Ground powder is subjected to high-temperature decomposition with formation on surface of filler metal nano- and microparticles.

EFFECT: simplified method of modifying filler for rubber and possibility of forming fine particles of variable-valence metals on surface of filler for use in production of rubber with high heat resistance, electrical conductivity and heat conductivity.
