Abstract

The application relates to a water-based cleaning agent containing polyhedral oligomeric silsesquioxane, which is made of the following raw material components: a first solubilizer; a second solubilizer; a chelating agent; an alkali metal hydroxide; Lotion; Defoamer; Bactericide; Hydrophilic Polyhedral Oligomeric Silsesquioxane; and Water. The present application also relates to a method of preparing a water-based cleaning agent comprising a polyhedral oligomeric silsesquioxane as described above. The cleaning agent of this application contains specific surfactants and hydrophilic polyhedral oligomeric silsesquioxanes. Through the synergistic effect of various raw material components, it can effectively remove organic pollutants and metal ions on the surface of different materials, and the decontamination rate is high. , especially suitable for cleaning silicon substrates in precision glass instruments and semiconductor industries.

Description

technical field [0001] The present application relates to the technical field of surface cleaning. Specifically, the present application relates to a water-based cleaning agent comprising polyhedral oligomeric silsesquioxane and a preparation method thereof. Background technique [0002] At present, when cleaning precision glass instruments or equipment in the industry, Freon, trichloroethane, carbon tetrachloride and chlorofluorocarbon solvent cleaning agents (referred to as ODS substances), alkaline water-based cleaning agents, water-based medium-temperature cleaning agents, and ultrasonic cleaning agents are generally used. Cleaning agents and methods such as cleaning, spray cleaning agent and ultrasonic combination cleaning. However, these knowledge and methods are not particularly effective in cleaning oily organic pollutants, with more residues and greater corrosion to the cleaned objects. Some cleaning agents may even pollute the environment and destroy the ecologica...
