Problems solved by technology

At present, for the cooling of the grinding process, water-soluble grinding fluids are widely used in the glass and quartz processing industries, but most of the formulas use banned nitrite as the main component, and have poor cleaning performance and inaccurate processing accuracy. The skin and eyes are irritated, and it is easy to cause health problems caused by "nitrite". At the same time, the waste liquid causes environmental pollution

Abstract

The invention discloses an optical product grinding fluid and a preparation method and an application thereof and the preparation method comprises the following steps: mixing 1-5 parts of long chain fatty acid salt lubricant, 10-20 parts of boracic antiwear agent, 0.1-3 parts of sinking agent, 10-25 parts of alcohol, 25-40 parts of alkylol amine, 1-8 parts of surfactant and 35-50 parts of water, and stirring at 40-80 DEG C to obtain the optical product grinding fluid. The grinding fluid has excellent cooling property, the product can be processed and cooled at the same time; the grinding fluid has no smell, is completely clear and transparent and is easy to observe for the operator; the washability is good, workpieces do not need special cleaning and only need to be washed with pure water, no residue is leaf; the product is non-toxic and has no harm to the operator and the environment; the product has good setteability and facilitates processing. The grinding fluid has good lubricating property; when grinding and drilling the optical product, the grinding fluid has high efficiency, less edge damage and high finish and the qualification rate can reach more than 96%. The preparationmethod of the grinding fluid has simple operation, low cost and good market promotion prospect.

Description

technical field [0001] The invention relates to a grinding fluid, in particular to a grinding fluid for optical products and its preparation method and application. Background technique [0002] In the grinding process of optical products such as glass and quartz, water-soluble grinding fluid is often used. Since a large amount of glass powder is produced during the grinding process, the cooling performance and cleaning performance of the grinding fluid are highly required. At present, for the cooling of the grinding process, the glass and quartz processing industries generally use water-soluble grinding fluids, but most of the formulas use banned nitrite as the main component, and have poor cleaning performance and inaccurate processing accuracy. The skin and eyes are irritated, and it is easy to cause health problems caused by "nitrite". At the same time, the waste liquid causes environmental pollution. In order to improve the cleaning performance during processing, the f...
