Method for preparing ceramic bond superhard material based on sol combined foaming method
A method for preparing a ceramic bond superhard material based on a sol combined foaming method belongs to the technical field of superhard material preparation, and comprises the following steps: S1, mixing a superhard abrasive, an auxiliary abrasive, ceramic bond powder, silica sol, a dispersing agent and deionized water to prepare mixed slurry; s2, adding a foaming agent into the mixed slurry, and uniformly stirring to prepare foam slurry; s3, adding a coagulation accelerator into the foam slurry while stirring, and injecting the foam slurry added with the coagulation accelerator into a mold for curing and molding to obtain a green body; and S4, sequentially performing primary drying on the green body under the conditions that the temperature is 25-65 DEG C and the humidity is 55-85%, performing secondary drying under the condition that the temperature is 65-110 DEG C, and performing firing treatment to obtain the ceramic bond superhard material. The method is used for preparing the ceramic bond superhard material which is uniform in molding density distribution and uniform in microstructure.
