Abstract

The invention discloses an optical glass cleaning agent and a preparation method thereof. The optical glass cleaning agent is composed of the following components in percentage by mass: 14 to 30 percent of propylene glycol, 1 to 5 percent of coconut diethanol amide, 0.8 to 1.5 percent of sodium carboxymethyl cellulose, 15 to 22 percent of sodium gluconate, 3 to 10 percent of alkyl glucoside, 12 to18 percent of an inorganic alkaline substance and the balance of water. The optical glass cleaning agent disclosed by the invention has the advantages of strong wetting power, strong dirt removing power and good washing effect, can be used for dirt including oil dirt, wax, carbon black and the like stuck on the surface of glass and also has extremely strong removing power on cerium oxide and ethylene oxide; the optical glass cleaning agent has small corrosiveness on the surface of the glass and is easy to rinse when optical glass is cleaned; the dirt also can be effectively prevented from being deposited again through a chelating effect between the sodium carboxymethyl cellulose and the sodium gluconate; and raw materials are environmentally friendly, have no irritation and are easily biodegraded. The quality of the washed product completely meets the requirements of customers and the optical glass cleaning agent is suitable for being popularized and applied.

Description

technical field [0001] The invention relates to an optical glass cleaning agent and a preparation method thereof, belonging to the technical field of cleaning materials. Background technique [0002] With the rapid development of modern optoelectronic technology industry, optical glass has been widely used as optoelectronic basic material in many aspects. [0003] Optical glass usually needs to go through cutting-edging-grinding-polishing and other processes in the production and use. These processes need cutting fluid, edging oil, grinding fluid, polishing powder, etc. to assist the operation, so there will be residues on the glass substrate. Contaminants such as glass powder, cutting fluid, polishing powder, grinding powder and asphalt. In addition, after the optical glass is coated, there will be residual stains such as dust, oil, and fingerprints on the glass surface. Therefore, in the optical glass processing process, a large number of cleaning steps are required, and...
