Optical polishing material

Abstract

The invention relates to an optical polishing material, belongs to the technical field of polishing materials and solves the technical problem that a polyurethane polishing pad is hard and brittle andis lack of toughness and elasticity in the prior art. The optical polishing material is prepared from components in parts by weight as follows: 100 parts of polyether polyol, 100 parts of diisocyanate, 1-2 parts of bisphenol A epoxy resin, 3-5 parts of chopped nylon fiber, 4-6 parts of chitin, 2-3 parts of silicone oil, -3 parts of chlorinated paraffin, 1-2 parts of ethylene glycol, 10-15 parts of maleic anhydride grafted polypropylene, 0.5-1 part of dimethylcyclohexylamine, 2-4 parts of acetone, 2-3 parts of shell powder, 2-3 parts of zinc stearate, 1-2 parts of tris(2,4-ditert-butylphenyl)phosphite, 1-2 parts of antioxidant 1010, 0.5-1 part of carbodiimide and 4-8 parts of cerium oxide. The optical polishing material has high tensile strength and good rebound resilience, wear resistance and die assembly performance, and is not prone to passivation.

Description

technical field [0001] The invention belongs to the technical field of polishing materials, and in particular relates to an optical polishing material. Background technique [0002] Glass has a long history and stable properties. It is an excellent material that has stood the test of time. It can not only be used for decoration, but also play an important role in various optical instruments, and can even be used to help buildings save energy and reduce noise. The surface of the glass is not smooth and clear enough, and it needs to undergo necessary surface polishing before being used, so polishing materials are produced. [0003] In the prior art, the polishing materials used in the early stage mainly include titanium oxide, iron oxide or silicon dioxide; in recent years, with the rapid development of electronic information technology, lenses, flat glass, liquid crystal displays (LCD), glasses, optical components The demand for glass substrates such as ceramic materials and...
