Gel reaction-based polycrystalline nanometer diamond grinding tool preparation method
The invention discloses a gel reaction-based polycrystalline nanometer diamond grinding tool preparation method. The preparation method comprises mixing deionized water and DMSO, uniformly dispersing a PAN copolymer in the mixed liquid, carrying out oscillation, swelling, high temperature dissolution and stirring until the mixed liquid forms a transparent solution without impurities, adding a nanometer diamond grinding material into the solution, adding a silane coupling agent into the mixture, carrying out full and uniform dispersion, carrying out deaeration on the solution in a vacuum baking oven, pouring the solution into a mold, carrying out gel molding in a freezer at a temperature of -20 DEG C, carrying out unfreezing under room temperature or heating conditions, then carrying out dehydration, carrying out pre-oxidation in a heating furnace and carrying out sintering carbonization molding. Acrylonitrile can be cured by gelation and is carbonized so that the acrylonitrile has high strength and good wear resistance, can be used as a grinding tool binder and can prevent gel grinding tool softening deformation in grinding.
