Water diamond lapping liquid and its preparation method and use

Abstract

The invention provides aqueous diamond polishing liquid, process for preparation and purpose. The main components are diadust, dispersion stabilizer, suspending agent, pH modifying agent, antiseptic agent, organic solvent and deionized water. The preparing technique of the invention is that organic solvent, diadust, prior prepared suspending agent, deionized water and dispersion stabilizer are mixed, then the mixture is stirred or supersonically dispersed uniformly, finally pH modifying agent and antiseptic agent are added, and the preparation is accomplished after shaking up. The lapping liquid can be widely used in grinding and polishing in various departments and areas of optical instruments, glasses, ceramics, rigid alloy, diamonds, artificial lens, optical fiber, LED display, integrated circuit, semiconductor, hard disk and the like. The lapping liquid can be kept in uniform and stable state, generates no precipitation, delamination or invalidation.

Description

technical field

[0001] The invention belongs to the field of precision grinding and polishing, and relates to a polishing liquid for grinding and polishing, in particular to a water-based diamond grinding liquid and its preparation method and application. Background technique

[0002] Diamond is currently known as the hardest substance in nature, its relative hardness (Mohs hardness) is 10, and its microhardness (square cone indentation method) is 98588MPa. The absolute hardness of diamond is 1000 times that of quartz and 150 times that of corundum. With its unparalleled high hardness and excellent mechanical and physical properties, diamond has become a tool for processing various hard materials. Diamond micropowder is the hardest ultra-fine abrasive, which has been widely used in machinery, aerospace, optical instruments, glass, ceramics, electronics, petroleum, geology, and military industry. It is an ideal material for high-hard materials such as artificial crystals an...
