Problems solved by technology

[0003] However, the test found that the existing optical glass often has small white spots on the lens, which cannot be cleaned with conventional cleaning agents, and the white spots are difficult to scrape off with a blade, and the scrap rate of the glass is very high
There are also cleaning agents specially used for optical glass in the prior art, but the existing cleaning agents are all strongly alkaline and corrosive to silicon dioxide. If the ratio of cleaning agent to water is adjusted to be thicker, the glass is prone to cracking after cleaning. White and bluish phenomenon, if the proportion of cleaning agent mixed with water is diluted, it will have no effect on cleaning white spots. Therefore, there is an urgent need in the market to provide a method that can completely remove white spots on optical glass and prevent strong alkali from affecting Silica Corrosion Cleaning Agents

Abstract

The invention relates to the technical field of a cleaning agent, and particularly relates to a soaking cleaning agent for optical glass and a preparation method thereof. The soaking cleaning agent comprises the following raw materials in percentage by weight: 3-8% of sodium hydroxide, 8-15% of anhydrous sodium sulphate, 2-6% of complexing agent, 1- 3% of wetting agent, 1-5% of triethanolamine and the balance of pure water, wherein the complexing agent is one of tetrasodium EDTA (ethylene diamine tetraacetic acid), organic phosphonate, hydroxy carboxylic acid salt or a compound complex, and the wetting agent is one of ethyl-glucoside, polyether modified silicone oil, polyether modified polysiloxane or a polyether modified polydimethylsiloxane polymer. The soaking cleaning agent for the optical glass, provided by the invention, can be used for completely removing white dots from the optical glass, effectively avoids corroding the optical glass, has a good cleaning effect and is simple in a preparation technology, convenient to use and beneficial to popularization and application.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to an optical glass immersion cleaning agent and a preparation method thereof. Background technique [0002] Optical glass refers to glass that can change the direction of light propagation and change the relative spectral distribution of ultraviolet, visible or infrared light. Optical glass in a narrow sense refers to colorless optical glass, and optical glass in a broad sense also includes colored optical glass and laser glass. , quartz optical glass, anti-radiation glass, ultraviolet infrared optical glass, fiber optic glass, acousto-optic glass, magneto-optical glass and photochromic glass, etc. Optical glass can be used to manufacture lenses, prisms, mirrors, windows, etc. in optical instruments. The components made of optical glass are key components in optical instruments. Affects the quality of the entire optical instrument. [0003] However, the test found that th...
