Problems solved by technology

At the same time, the effective substances in the cleaning agent will be consumed quickly, which will greatly limit the use time or life of the cleaning agent, and bring great inconvenience to the large-scale and continuous production of the enterprise.
[0008] (3) Since the saponified or emulsified oil is dispersed or dissolved in the cleaned sewage, it is difficult to separate it, resulting in a high content of organic matter in the cleaned sewage, which is difficult to handle and brings new cleaning pollution problems , which greatly increases the sewage treatment cost of the enterprise and limits the promotion and application of water-based cleaning agents in the industrial field
Its surfactants are composed of AEO-9, TX-10, 6501, LAS and other components, with proper foaming performance and good decontamination performance, but AEO and TX series have strong emulsifying ability, solubilize and emulsify oil stains in water, greatly reducing The service life of the cleaning solution is shortened, and the cost of sewage treatment is also increased, and TX-10 is a difficult biodegradable component, which will cause continuous pollution to the water body
[0010] Chinese patent CN 105002007 A discloses a kind of environment-friendly optical glass water-based cleaning agent, which is mainly composed of nonionic surfactant, anionic surfactant, cleaning aid, corrosion inhibitor, penetrating agent and deionized water. The surfactant used still has the problem of too strong emulsifying power, and a large amount of oil is emulsified in water, resulting in secondary cleaning pollution.

Abstract

The invention discloses a peeling type waterborne cleaning agent for optical glass. The peeling type waterborne cleaning agent is prepared from the following raw materials in percentage by weight: 3 percent to 8 percent of isomeric alcohol polyoxyethylene ether, 2 percent to 5 percent of fatty alcohol polyoxyethylene polyoxypropylene ether, 1 percent to 3 percent of isomeric alcohol polyoxyethylene ether phosphate, 1 percent to 3 percent of fatty acid methyl ester polyoxyethylene ether sodium sulfonate, 0.5 percent to 2 percent of polyethylidene polyqudinedrnium, 0.2 percent to 1 percent of a fluorocarbon type surfactant, 5 percent to 10 percent of a washing assistant, 2 percent to 5 percent of a metal chelating agent and the balance of water. The peeling type waterborne cleaning agent for the optical glass, disclosed by the invention, has extremely low surface tension and prominent capabilities in the aspects of wetting effect and permeability; the peeling type waterborne cleaning agent has an extremely low emulsifying capability and basically does not emulsify oil dirt; a peeling type oil dirt washing manner is adopted and the consumption of useful-effect components in the cleaning agent is effectively reduced, so that the service life of the cleaning agent is greatly prolonged and the sewage treatment cost is greatly reduced; the popularization and application of the waterborne cleaning agent are facilitated; meanwhile, the peeling type waterborne cleaning agent does not contain water body polluting components including phosphorus, APE (Alkylphenol Ethoxylates) and the like, so that the peeling type waterborne cleaning agent has environment-friendly components and is easy to degrade.
