Problems solved by technology

Most of the existing corundum abrasives are preliminary processed products, the performance is not obvious, and they are mostly used for low-end abrasives
In the current coating process, due to the volatilization of the binder used in the calcination process, certain harmful gases will be generated, causing environmental pollution and harmful to the human body. The volatilization of the binder will damage the calcination equipment and increase the production cost of the coating. The tempering temperature is relatively low, the process is only covered by the coating, and the performance improvement is limited

Abstract

The invention relates to a preparation method of a zirconium film grinding material, and belongs to the technical field of grinding materials. The method comprises the following specific steps: melting low-sodium aluminum oxide, and conducting cooling with water to obtain blocky aluminum oxide crystals; crushing and screening the blocky aluminum oxide crystals by a roller crusher and a jaw crusher; uniformly mixing zirconium oxide and soft water according to a mass ratio of 0.5:5 to 1.5:5, carrying out wet ball milling to obtain a zirconium oxide mother solution, and uniformly applying the zirconium oxide mother solution on the surfaces of aluminum oxide particles through coating; sintering the alumina particles coated with the zirconium oxide mother liquor at 200 DEG C to obtain zirconium film alumina particles; feeding the sintered zirconium film alumina particles into a natural gas tunnel kiln, conducting calcining at 1300 DEG C, and conducting tempering; and feeding a finished product under negative pressure in a screening workshop, conducting wind washing, and conducting screening, packaging and stoage. According to the method, the surface of aluminum oxide is evenly covered with a layer of zirconium film, the production process is simple, the influence on the surrounding environment is small, and the properties such as hydrophilicity and toughness are excellent.

Description

technical field [0001] The invention belongs to the technical field of abrasive materials, and in particular relates to a preparation method of a zirconium film abrasive material. Background technique [0002] Corundum abrasive is the largest amount of traditional abrasives and the main raw material in abrasive tool production. Most of the existing corundum abrasives are preliminary processed products with inconspicuous performance, and are mostly used for low-end abrasives. In the current coating process, the binder used in the calcination process will produce certain harmful gases due to the volatilization of the binder, which will cause environmental pollution and be harmful to the human body. The volatilization of the binder will damage the calcination equipment and increase the production cost of the coating. The tempering temperature is relatively low, the process is only covered by the coating, and the performance improvement is limited. Contents of the invention ...
