Acidic cleaning agent as well as preparation method and application thereof

Abstract

The invention relates to an acidic cleaning agent as well as a preparation method and application thereof. The acidic cleaning agent comprises the following components in percentage by mass: 5%-20% of organic acid, 3%-10% of inorganic acid, 5%-30% of a reducing agent, 1%-8% of a pH buffering agent, 1%-8% of a surfactant, 1%-5% of a chelating agent and the balance of water. The organic acid, the inorganic acid and the pH buffering agent in a specific ratio are matched to provide a specific acidic cleaning environment, and in the acidic environment, the polishing powder shows strong oxidizing property; and meanwhile, the reducing agent with a specific ratio is added, so that the polishing powder and the reducing agent are subjected to a chemical reaction quickly in a specific acid environment, the wetting and dispersing effects of the chelating agent and the surfactant with a specific ratio are matched, and all the components with specific ratios are coordinated and matched, so that the polishing powder on the surface of glass can be treated very quickly, and the glass is not damaged.

Description

technical field [0001] The invention relates to the field of glass cleaning, in particular to an acid cleaning agent and its preparation method and application. Background technique [0002] In the production process of glass components, in order to reduce the roughness of the glass surface, the surface of the glass needs to be polished. During the polishing process, the surface of the glass is usually polished with polishing powder, and a part of the polishing powder remains on the glass surface after polishing. On the one hand, the polishing powder particles remaining on the surface of the glass element will corrode the surface of the glass element. For example, the remaining polishing powder particles on the optical glass element after precision polishing are one of the key factors affecting the ability of the element to resist laser radiation damage; On the other hand, after the glass component is assembled on the electronic product, the polishing powder remaining on th...

Problems solved by technology

However, electronic glass components are mainly made of high-aluminosilicate, and its main component is silicon dioxide. Traditional alkaline cleaners will corrode the glass due to too strong alkalinity, resulting in hazy scratches, bluish and other undesirable phenomena. ; while the traditional acidic cleaning agent adds additives such as surfactant and dispersant to the acidic system, so that the polishing powder on the glass surface is cleaned. The problem of low removal efficiency of polishing powder
