Polishing solution for optics lens

Abstract

The invention provides a polishing solution for an optics lens. The polishing solution comprises the following components in parts by weight: 10 to 15 parts of deionized water, 20 to 30 parts of zinc nitrate, 8 to 12 parts of an organic silicon defoamer, 15 to 20 parts of nonylphenol polyoxyethylene ether, 5 to 8 parts of hydrogen peroxide, and 50 to 80 parts of aluminum oxide. The polishing solution is safe and nontoxic, and good in polishing performance, and can reduce the reject ratio during optics lens polishing, reduce scratches and improve the grinding quality.

Description

technical field [0001] The invention relates to the technical field of surface treatment, in particular to a polishing solution for optical lenses. Background technique [0002] In the manufacturing industry of optical lenses, the control of the preparation process is the key to the production of optical lenses. After the optical lens is finely ground with abrasive fluid, there is still a crack layer about 2-3m thick on the surface. The method to eliminate this crack layer is polishing. Among them, for processing optical lenses, especially the polishing liquid used for grinding optical lenses has a great influence on this process. The traditionally used polishing liquid has the defects of long processing time, unstable product quality and poor overall operation efficiency. Contents of the invention [0003] In view of the various problems mentioned in the background technology, the object of the present invention is to provide a polishing solution for optical lenses that...
