Abstract

The invention belongs to the technical field of preparation of a resin matrix diamond polishing grinding disc, and particularly relates to a diamond grinding disc for artificial zirconium jewel polishing. The diamond grinding disc is prepared from the following raw material components in percentage by mass: 70-90% of diamonds, 1.5-5% of hexagonal boron nitride nanosheets, 6-18% of high molecular resin powder, 1-3% of cerium oxide, 1-3% of zirconium oxide and 0.5-1% of stuffing fused alumina zirconia. A polishing grinding disc manufactured by a resin grinding disc manufacturing material for artificial zirconium jewel polishing is good in material compactness, is high in hardness, is smooth in surface, is moderate in pore, is pressed by low-temperature mould pressing, is free from scratch-induced damages to processing of high-hardness fragile workpieces such as jewels and the like, is high in processing precision, is especially suitable for artificial zirconium jewel polishing and is highly welcomed by users; and the jewels polished by the diamond grinding disc is good in glossiness.

Description

technical field [0001] The invention belongs to the technical field of preparation of resin matrix diamond polishing discs, and in particular relates to a diamond grinding disc for polishing artificial zircon gemstones. Background technique [0002] At present, domestic and foreign gem manufacturers have put forward a set of comprehensive polishing basic theories for gem grinding and polishing, which has laid a foundation for improving the polishing accuracy of gems. However, in the polishing of hundreds of gemstones, due to the great differences in the crystal structure and characteristics of various gemstones, there are many factors affecting the polishing effect of gemstones, so it is not easy to master the polishing techniques of various gemstones. For zirconium gemstones whose crystal structure is mainly cubic zirconia, due to their high hardness and high brittleness, impurities and other coarse-grained foreign matter can easily scratch the gemstone surface during the f...
