Intelligent controlling wall coating material and preparation method thereof

Abstract

The invention relates to a wall coating material with intelligent regulation and a preparation method thereof. The invention uses silylated polyether as a main raw material, which is co-condensed with a former body of multi-component metal oxide, thus making the coating material. The coating material essentially consists of silylated polyether and multi-component metal oxide former body. The preparation method thereof is: first, the silylated polyether, alkoxyl metal compound M(OR)n, acetylacetone coordination complex or inorganic metallic salt and silylated perfluoropolyether are added into anhydrous solvent, stirred under acid condition, filled with nitrogen at 60 to 150 DEG C, and refluxed for 1 to 5 hours; separation catalyst solution after reaction is steamed out water to get anhydrous sol which is added with curing agent, solubilizer, stabilizer and then is stored; when in use, solvent is added to dilute according to the requirements. The products of the invention is of strong toughness and intelligent with multi-function of photocatalysis perception, self-cleaning, clean air, regulation of temperature, humidity and oxygen, humidity sensing, plugging, etc. The invention is suitable for internal and external wall coating materials and has wide application.

Description

technical field [0001] The invention is an intelligent control and self-cleaning wall coating material. Background technique [0002] At present, the coatings with functions such as self-cleaning and intelligent temperature regulation are only used for architectural glass and ceramics. Its preparation methods include (1) physical vapor deposition (PVD) film-forming method; (2) chemical vapor deposition (CVD) method; (3) sol-gel powder making high-temperature sintering film-forming method, etc., and smart glass also uses interlayer method , in short, the above method is characterized by high investment costs and high production costs. Currently, the price of TiO2 self-cleaning glass is 300 yuan / m 2 , the price of smart glass is 400 US dollars - 1000 euros / m 2 Domestic 3000-4000 yuan / m 2 . At present, the wall coating does not have the above functional characteristics. The present invention uses sol-gel as the basic principle to prepare poly-inorganic metal oxide co-cond...

AI Technical Summary

Problems solved by technology

[0007] 1) Due to the limitation of high-temperature film-forming process, it is difficult to construct on-site in a large area, resulting in limited application range

[0008] 2) Since the sol prepolymer produced by the preparation process has a network molecular structure and a gel state, and the particle size distribution range is wide, it is not suitable for spraying at room temperature

[0009] 2. The shortcomings in product characteristics caused by a single composition structure are:

[0010] 1. The function is single; 2. The functional characteristics cannot reach the expected effect; 3. The photocatalytic effect cannot be judged intuitively
