A kind of oily polishing liquid and its preparation method and application

Abstract

The invention relates to an oily polishing liquid and its preparation method and application, belonging to the technical field of precision polishing. The oily polishing liquid of the present invention is composed of the following components in parts by weight: 5-20 parts of α-phase nano-alumina powder, 69-85 parts of mineral oil, 0.5-5 parts of hydrophobically modified silicon oxide, 1-20 parts of oily dispersant 5 servings. The oily polishing liquid contains hydrophobically modified silicon oxide and α-phase nano-alumina powder. The hydrophobically modified silicon oxide can not only increase the polishing effect, but also increase the thixotropy of the oily polishing liquid. Adjust the viscosity of the liquid to 50-1000cp. Good adhesion to the steel wire, and good fluidity; α-phase nano-alumina powder is not easy to cause scratches during the polishing process due to its low cost, good wear resistance, and fine particle size.

Description

technical field [0001] The invention relates to an oily polishing liquid and its preparation method and application, belonging to the technical field of precision polishing. Background technique [0002] In the modern optical communication industry, optical fiber connectors are the most widely used optical passive devices that have the greatest impact on the transmission quality of optical fiber communication. As the core part of the connector, the processing quality of the ceramic ferrule has a great influence on the loss of the connector. Domestic research mainly focuses on the ultra-fine grinding and polishing of the end face and outer surface of the optical fiber connector, but less research on the precision polishing of the inner hole of the ferrule. The processing accuracy of the inner hole of the ferrule directly determines the optical performance of the fiber optic connector - insertion loss and return loss. [0003] At present, special equipment is used for the inn...

Problems solved by technology

[0007] The polishing liquid and the polishing paste in the above-mentioned prior art are not enough to meet the requirements, mainly in: (1) the wettability of the water-based polishing liquid or the polishing paste and the steel wire is poor, and then the adhesion of the polishing liquid and the polishing paste on the steel wire surface is relatively poor. Poor, not conducive to polishing; (2) The viscosity of the oily polishing liquid is low, the suspension of the abrasive is poor, and it cannot evenly adhere to the steel wire; while the viscosity of the oily polishing paste is too high and lacks fluidity, it cannot take away the polishing waste, resulting in early polishing. The efficiency is high, and the polishing efficiency in the later stage decreases too fast, and in addition, it will affect the smoothness of the movement of the steel wire in the micropore; (3) the diamond in the prior art is easy to disperse in water, and it is easy to agglomerate after drying, and it is secondarily dispersed in oil Difficult, prone to scratches during polishing

[0008] Therefore, there is still a lack of a polishing solution that can improve the wettability of the polishing solution and the steel wire, make the viscosity of the polishing solution moderate, and can take away the polishing waste in time during use.
