Abstract

The invention discloses a cleaning agent for optical glass, which comprises the following components in weight percentage: 2-4% of long carbon chain dibasic acid; 6-10% of an anionic surfactant; 2-4% of an inorganic base; 2-6% of a nonionic surfactant; 2-4% of a special surfactant; 6-12% of a chelator; 10-20% of an organic base; and 40-70% of deionized water, wherein the long carbon chain dibasic acid is dicarboxylic acid with 21 carbon atoms, the anionic surfactant is dodecylbenzene sulfonic acid, the inorganic base is industrial NaOH, the nonionic surfactant is primary alcobol ethoxylate AEO9, the special surfactant is sodium POE nonylphenol ether sodiosulfosuccinate, the chelator is a mixture of Tetrasodium Ethylenediamine Tetraacetate and sodium gluconate, and the organic base is diethanol amine. The cleaning agent for optical glass provided by the invention has low corrosivity and good cleaning effect.

Description

technical field [0001] The invention relates to an optical glass cleaning agent, which is widely used in substrate glass, ITO (Indium Tin Oxide, indium tin oxide) coated conductive glass, tempered glass and acrylic (acrylic, organic glass, chemical name is polymethyl methacrylate) board screen printing The invention relates to cleaning before and after ink, belonging to the technical field of cleaning for electronic industry. Background technique [0002] With the rapid development of my country's LCD (Liquid Crystal Display, liquid crystal display) industry and touch screen industry, the demand for optical glass cleaning agents is increasing, and at the same time, higher requirements are placed on the cleaning performance and environmental protection performance of cleaning agents. [0003] In the process of ITO (Indium Tin Oxide, indium tin oxide) conductive glass, the substrate glass should be thoroughly cleaned first to ensure the quality of the ITO coating; in the LCD p...
