preparation example 1

[0035] An emulsified alkane, the preparation method is: after mixing 20g of alkane with 20g of water, add 4g of surfactant dropwise while stirring, and raise the temperature to 70°C, then stir for 15min under the condition of heat preservation, and naturally cool to 25°C to obtain the emulsified alkane The alkane used is decane, and the surfactant used is octadecyl dimethyl benzyl ammonium chloride.

preparation example 2-7

[0037] Preparation Examples 2-7 are all based on Preparation Example 1, and differ from Preparation Example 1 only in that the conditions for preparing emulsified alkanes and the types of alkanes used are different, see Table 2 for details.

Abstract

The application relates to the field of grinding wheels, and specifically discloses a superhard CBN ceramic grinding wheel and a preparation method thereof. The preparation raw materials of superhard CBN ceramic grinding wheel are calculated by weight, including 50-90 parts of CBN abrasive, 10-50 parts of low-temperature glass powder, 3-15 parts of emulsified alkane, 0.2-2 parts of composite wetting and dispersing agent, and 0.2-2 parts of composite wetting and dispersing agent. The agent is a mixture of polyoxyethylene ether and inorganic high molecular polymer; its preparation method is: S1, mix CBN abrasive, low-temperature glass powder, emulsified alkane, and composite wetting and dispersing agent to prepare a blank; S2, put the blank into It is pressed into the grinding wheel mold and sintered to make a superhard CBN ceramic grinding wheel. The superhard CBN vitrified grinding wheel of the present application has a higher yield.

Description

technical field [0001] The application relates to the field of grinding wheels, more specifically, it relates to a superhard CBN ceramic grinding wheel and a preparation method thereof. Background technique [0002] Grinding wheel is a porous body made by compacting and firing, and is the most important type of abrasive tool in grinding. The grinding wheel performs rough grinding, fine grinding, slotting or cutting off the outer circle, inner circle, plane and various profiles of metal or non-metallic workpieces through high-speed rotation. There are many kinds of grinding wheels, which can be divided into ordinary abrasive grinding wheels and superabrasive grinding wheels, among which superabrasive grinding wheels are mainly superhard CBN ceramic grinding wheels. [0003] Superhard CBN ceramic grinding wheel is a ceramic grinding wheel made of cubic boron nitride abrasive as the main raw material. It is usually made of CBN abrasive, glass powder, dextrin powder and water g...
