Abstract

The invention belongs to the technical field of high polymer materials, and particularly relates to an anti-fouling self-cleaning face coating agent and an anti-fouling self-cleaning face coating ETFE film with a lotus leaf effect. A sol-gel method is designed to prepare inorganic and organic hybrid particles, a silane coupling agent is utilized to modify the inorganic and organic hybrid particles, the modified hybrid particles are utilized to prepare the antifouling self-cleaning face coating agent, the antifouling self-cleaning face coating agent can form an organic-inorganic hybrid particle coating on an ETFE film, the smoothness degree of the surface of the ETFE film is reduced, and the antifouling self-cleaning face coating agent can be used for cleaning the ETFE film. A micro-bulge structure with a micro-nano size is formed on the surface, so that a super-hydrophobic structure is realized, and a self-cleaning function is achieved. The antifouling self-cleaning facial coating agent provided by the invention can also be used on the surfaces of other films or other materials.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an antifouling self-cleaning surface coating agent and an antifouling self-cleaning surface coating ETFE film with lotus leaf effect. Background technique [0002] Polymer materials are divided into three categories: general polymer materials, special polymer materials and functional polymer materials. General-purpose polymer materials refer to polymer materials that can be produced on a large scale and have been widely used in major areas of the national economy such as architectural membranes, transportation, agriculture, electrical and electronic industries, and people's daily life. With the continuous development of science and technology, polymer materials play a more important role in the field of architectural membranes. Among them, the self-cleaning performance of polymer architectural membrane materials is an important indicator. [0003] Zhou Dun...
