[0004] Chinese patent CN 102604751A discloses a cleaning agent for optical glass, the main components of which are long carbon chain dibasic acids, surfactants, chelating agents and inorganic bases. Good, and contains inorganic strong alkali substances, which are easy to corrode some sensitive glass
This kind of cleaning agent uses inorganic weak base as buffer agent. Although it has no corrosion to sensitive material glass, it has poor cleaning effect on grinding powder, and the yield of good products after cleaning is low.

Abstract
At present, many enterprises use a full-automatic optical glass cleaning line to clean ground optical glass in order to improve productivity; however, the full-automatic optical glass cleaning line ishigh in running speed, and higher requirements are raised for an optical glass cleaning agent matched with the full-automatic optical glass cleaning line. The invention aims to provide an optical glass cleaning agent applicable to a full-automatic cleaning line and capable of realizing ultrasonic and spray cleaning of ground optical glass. The ptical glass cleaning agent comprises the following components in parts by weight: 1-10 parts of a surfactant, 10-30 parts of an acidic chelating agent, 10-25 parts of an alkaline chelating agent, 0.2-5 parts of a dispersing agent and 40-75 parts of water. Compared with the prior art, different raw materials, proportions and manufacturing processes are adopted; and compared with a conventional optical glass cleaning agent, the optical glass cleaningagent of the invention has the advantages that cleaning effect is stronger and glass is not corroded, so working efficiency is effectively improved, and productivity is enhanced.
Description
technical field [0001] The invention belongs to the technical field of chemical cleaning agents, and relates to a cleaning agent for cleaning residual polishingpowder on the surface of optical glass, in particular to an optical glass cleaning agent used in a fully automatic optical glass cleaning line and a preparation method thereof, especially The invention relates to an optical glass cleaning agent for spraying and a preparation method thereof. Background technique [0002] Polishing is an important process in the production of optical glass that determines its processing efficiency and surface quality (appearance and precision). Optical glass needs to use solidpolishingpowder during the grinding or polishing process. The main pollutants in the polishing process are polishing powder and asphalt, and there will be paint flakes in the optical glass processing process of a few enterprises. Among them, the types of polishing powder are different, and they are generally al...
