Abstract

The invention relates to the technical field of high-precision grinding and polishing, in particular to a diamond polishing film as well as a preparation method and application thereof. The diamond polishing film comprises a base material and a polishing coating, wherein the polishing coating is mainly prepared with the following components of, by weight: 4-6 parts of coupling-process diamond micro-powder, 3-9 parts of adhesives, 1-5 parts of solvents and 0.04-1 of a hardening agent. The preparation method comprises the following steps that the coupling-process diamond micro-powder, the adhesives, the solvents and the hardening agent are mixed in proportion, a curing agent is added, then the mixture is used for coating the surface of the base material, and curing is conducted to obtain thepolishing film. The diamond polishing film prepared through the method has the advantages that in the processing process of an optical communication device, such as an optical fiber connector, the processing requirements of an optical fiber connector can be effectively met, the processing yield is improved, and the service life of the polishing film is prolonged.

Description

technical field [0001] The invention relates to the technical field of high-precision grinding and polishing, in particular to a diamond polishing film and its preparation method and application. Background technique [0002] With the development of science and technology, the precision machining of many high-tech components is inseparable from grinding and polishing. Among them, the coated polishing film has attracted more and more attention because of its convenient use and high processing efficiency, and its application fields tend to increase. , mainly used for polishing of hard materials such as metal, ceramics and glass. [0003] Generally, precision devices such as optical communication devices, optical lenses, porcelain plates, and semiconductor monocrystalline silicon have high requirements for surface finish. If the surface has unevenness, scratches, or foreign matter attached, the design accuracy and performance will not be guaranteed. Therefore, the final Surfac...
