Problems solved by technology

Traditional cleaning agents are generally organic solvent-based cleaning agents. Organic solvent-based cleaning agents have a faster volatilization speed when cleaning cutting fluid, abrasive paste and fingerprints on the surface of optical glass. However, the main components of these solvent-based cleaning agents are halogenated Hydrocarbon solvents, aromatic hydrocarbon solvents, short-chain alkane solvents, etc., will cause harm to human health after inhalation, and there are great fire safety hazards
[0004] In addition, although cleaning agents that use water as a solvent have also appeared in some documents in the prior art, the use of these water-based cleaning agents generally has poor cleaning effects, a large amount of cleaning agent liquid on the glass surface, and stains after cleaning. In the one-step process, the adhesion of the coating on the glass surface is weak, and these water-based cleaning agents can only obtain relatively good cleaning effects when the dilution ratio is small

Abstract

The invention discloses an optical glass cleaning agent. The optical glass cleaning agent is prepared from the following components: 10-24% of potassium hydroxide, 1-10% of tetrasodium ethylenediamine tetraacetate or nitrilotriacetic acid, 1-5% of fatty alcohol-polyoxyethylene ether, 1-8% of triethanolamine, 1-5% of dibutyltin dilaurate, 1-10% of isomeric C13 fatty alcohol-polyoxyethylene ether and / or C8-10 ethoxy propoxy fatty alcohol and the balance of purified water, wherein the total mass percentage of the components is 100%. The optical glass cleaning agent disclosed by the invention has the advantages of good cleaning effect, high cleaning efficiency and low cost and is safe and environment-friendly. Particularly, the optical glass cleaning agent can enhance the adhesion of a coating to the glass surface in the next process.

Description

technical field [0001] The invention relates to a cleaning agent for optical glass, which belongs to the field of cleaning agents. Background technique [0002] Optical glass is the foundation and an important part of the optoelectronic technology industry. Especially after the 1990s, with the continuous integration of optics, electronic information science, and new material science, the application of optical glass as the basic material of optoelectronics in the three major fields of optical transmission, optical storage, and optoelectronic display has advanced by leaps and bounds. Social informatization, especially one of the basic conditions for the development of optoelectronic information technology. [0003] In the production process of optical glass, there are a large number of links that need to be cleaned, and it is required to be cleaned without residue. Traditional cleaning agents are generally organic solvent-based cleaning agents. Organic solvent-based cleanin...
