Abstract

The invention discloses a neutral cleaning agent for coated optical glass. The neutral cleaning agent is prepared from the following raw materials in parts by weight: 2-5 parts of a complexing agent,10-15 parts of a dispersing agent, 2-8 parts of a surfactant, 0.05-1 part of a foam inhibitor, 0.01-0.05 part of essence, 0.02-0.1 part of a preservative and the balance of water, wherein the sum of the parts of the raw materials is 100 parts. According to the invention, the foam inhibitor is prepared by selecting one or two of ethylene glycol monobutyl ether, ethylene glycol monomethyl ether, diethylene glycol monomethyl ether, diethylene glycol monobutyl ether and tributyl phosphate as defoaming component(s), thus not only avoiding the corrosion of an anti-fingerprint film layer on the surface of the glass, but also inhibiting the generation of foams; therefore, the phenomenon of residual silicon-containing defoaming agents is effectively avoided; the effects of no residue, low foam andeasy rinsing are achieved; and the technical problem that in the prior art, the cleaning agent is poor in defoaming effect is solved.

Description

Technical field [0001] The embodiment of the present invention belongs to the technical field of cleaning agents, and particularly relates to a neutral cleaning agent after optical glass coating. Background technique [0002] Optical glass is the foundation and important part of the optoelectronic technology industry, such as camera lenses, cell phone covers, and experimental microscope lenses. Because of the high manufacturing cost, the cleaning agent selected in the cleaning process is also high, and the cleaning agent is required. It meets the following conditions: low surface tension, good wettability, good permeability, etc. Solvent cleaning is a more traditional method, and its advantages are fast cleaning speed and relatively high efficiency. The solvent itself can be continuously distilled and regenerated, but the disadvantages are also obvious. These water-based cleaning agents generally have the problem of high foam during cleaning. In order to prevent too much foam dur...
