Description
Technical Field
The invention belongs to the technical field of corundum abrasives, and particularly relates to a preparation method of a chrome corundum composite abrasive.

Abrasives are materials that play a role in grinding, lapping, and polishing; abrasives are particulate materials that are manufactured in an artificial manner to a specific grain size to produce grinding, polishing and abrading tools that remove the remainder of the material. In order to be suitable for the processing requirements of various workpiece materials, the abrasive material has the following basic properties: (1) very high hardness; (2) a certain toughness; (3) a certain mechanical strength; (4) high temperature stability; (5) chemical stability; (6) better pelletization manufacturability.
Abrasives have an irreplaceable role in industrial applications, and with the continuous progress of industry and science, the application range of abrasives is larger and larger, and the performance requirements are gradually increased. The chromium corundum is prepared by adding a proper amount of chromium oxide (Cr 2 O 3 ) The main ingredient of the prepared material is Al 2 O 3 More than 97.5 percent of Cr 2 O 3 Accounting for more than 1.3 percent. The toughness of the chrome corundum is higher than that of the white corundum, the hardness of the chrome corundum is similar to that of the white corundum, and the chrome corundum has good cutting performance. The application range of the chrome corundum in grinding processing is similar to that of the white corundum, but the durability of the grinding tool and the surface roughness of the processed workpiece are slightly better than those of the white corundum, so that the chrome corundum is suitable for precision cutters, measuring tools and instrument parts.
As the traditional electric smelting process is adopted for the most of the manufacturing of the chrome corundum abrasive, few corundum abrasive are manufactured by a sintering method. This is because alumina has a high melting point, is difficult to sinter at low temperatures, and the excessive temperature causes abnormal growth of grains, resulting in an increase in porosity, and damages the uniformity and compactness of its microstructure, thereby damaging its performance. Therefore, a novel preparation method of the chrome corundum composite abrasive is necessary to be explored.

The interaction between the raw materials of the binding agent ensures compact microstructure, less air holes and good interface bonding state.
According to the chrome corundum composite abrasive, the mixed solution composed of the aluminum dihydrogen phosphate, the copper oxide and the sodium hexametaphosphate is used as the wetting agent, the copper oxide serves as the curing agent, the polymerization degree of the phosphate mixture is increased along with the increase of the temperature in the sintering process, so that the large molecular polyphosphoric acid with the three-dimensional network structure is formed, and the large molecular polyphosphoric acid with the three-dimensional network structure reacts with the copper oxide to form the high molecular polymer with the network structure, so that the compressive strength of the composite abrasive is greatly improved.
