Rare earth polishing disc

Abstract

The invention discloses a rare earth polishing disc which has high cutting efficiency, good wear resistance property and high surface brightness. To be different from the existing polishing disc, the rare earth polishing disc mainly comprises rare earth polishing powder, resin, magnesium sulfate or white sugar, curing agent and accelerating agent, wherein the rare earth polishing powder comprises the following compositions in percentage by weight: more than or equal to 60 percent but less than or equal to 99.99 percent of cerium oxide, and more than or equal to 0.01 percent but less than or equal to 40 percent of lanthanum oxide, the content of the rare earth polishing powder can achieve 65 percent, the relative particles of the rare earth polishing powder is small, the brightness of a polished object can be greatly improved compared with the original polishing disc, and the polishing time of the surface of a product can be shortened to be about 0.6 second, so that the working efficiency is improved, the wear resistance property is greatly improved, 1,000-1,200 NO.40 crystal balls can be polished by the original polishing disc with the same size, while the rare earth polishing disc can polish 4,000 NO.40 crystal balls.

Description

technical field [0001] The invention relates to a rare earth polishing disc. Background technique [0002] The polishing disc is mainly used in the polishing of various glass surfaces and sides, rhinestones, crystal ornaments, etc. It is also an indispensable polishing abrasive tool for the processing of high-end glass handicrafts. At present, the main method is to fix the polishing disc on the turntable of the polishing machine for crystal, Polishing of glass handicrafts, etc., can be used for single block and disc processing and batch processing on the assembly line. In the past, the polishing disc was mainly made of rare earth cerium oxide, fiber mesh as the binder, adding accelerators, grinding aids, and pH stabilizers. This kind of polishing disc often has low cutting rate and low surface brightness. The disadvantage is that it takes a long time to polish a product, and the work efficiency is low; and the wear resistance is not high, the service life is short, and it n...
