ABRASIVE MIXTURE FOR ABRASIVE PASTES AND TOOLS AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2014 - IPC B24D3/00 B24D18/00 C09K3/14 

FIELD: chemistry.

SUBSTANCE: invention relates to mechanical engineering and can be used in making abrasive tools and pastes for polishing articles made of solid materials and paint coats. The abrasive mixture contains as a cutting component abrasive particles which are mixed with a binding material and consist of carbon nanoparticles in form of graphenes with monoatomic thickness with sizes ranging from 0.1 mm to 2 mm and graphene pumice, which is graphene clusters in form of stacks of plane-parallel graphenes joined to each other at one of their ends. When preparing the abrasive mixture, the cutting component is mixed with binding material in a vacuum chamber at low pressure. Pressure is then raised to atmospheric pressure before the binding material begins to harden.

EFFECT: high wear resistance of abrasive pastes and tools.
