Abstract

The invention provides an environment-friendly film for treating volatile organic compounds in air and a preparation method of the environment-friendly film. The environment-friendly film comprises aglass fiber cloth substrate, wherein the surface of the glass fiber cloth substrate is coated with an ionic liquid coating layer, and the surface of the ionic liquid coating layer is coated with a silicon dioxide gel layer; tartaric acid and sulfamic acid are dispersed in the ionic liquid coating layer; and tartaric acid and sulfamic acid are dispersed in the silicon dioxide gel layer. According to the environment-friendly film, tartaric acid and sulfamic acid are dispersed in silicon dioxide gel and ionic liquid, and the glass fiber cloth is coated with silicon dioxide gel and ionic liquid, so that the environment-friendly film has good collection adsorbability to volatile matters of organic compounds such as hydrocarbon, ketone, ester, alcohol, phenol, aldehyde and amine, and sulfamic acid, ionic liquid and tartaric acid in the environment-friendly film are capable of effectively permeating, dissolving and decomposing the organic compounds, and the defects in the prior art that the volatile organic compounds are difficult to be effectively absorbed and treated are remedied.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and relates to an environment-friendly film for controlling air volatile organic compounds and a preparation method. Background technique [0002] Volatile Organic Compounds (Volatile Organic Compounds, hereinafter referred to as VOCs) are the most common type of pollutants emitted by petrochemical, pharmaceutical, printing, shoemaking, painting and other industries, including benzene, toluene, xylene and other volatile organic compounds. General furniture, automobile, metal and non-metal component processing, silk screen printing and other processes will also produce volatile organic waste gas. Now, with the development of industry and the improvement of people's living standards, the emission of VOCs is increasing day by day, and has the characteristics of wide range and large emission. Most of these organic substances are toxic and can participate in photochemical reactions to for...
