Abstract

The invention provides a preparation method of an anti-glare nano anti-microbial composite functional coating: first, the improved sol-gel method is used to prepare silica particles enriched with hemispherical strontium oxide on the surface; An organic solvent is used to coat and disperse the hemispherical strontium oxide-rich silica particles on the surface. Then, the swollen PMMA polymer particles are used to uniformly wrap the strontium oxide-rich silica particles as light-scattering particles, and then prepare a sheet of silicon-doped alumina / graphene powder and make an ethanol slurry. Scattering particles, silicon-doped alumina / graphene slurry, special resin, adhesion promoter, and graphene composite anti-virus powder are mixed with ultrasound to make anti-glare nano-anti-microbial composite functional coating liquid. The coating solution is coated on PET film or glass to prepare a coating, which has anti-glare, anti-microbial, strong wear resistance, high bending strength and fracture toughness, and has wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of preparation of nano functional coatings, in particular to a preparation method of an anti-glare nano anti-microbial composite functional coating. Background technique [0002] Glare mainly refers to a human visual condition. Under such visual conditions, the human body will feel uncomfortable, which will also reduce the resolution of the human eye. The most direct cause is the brightness of the human visual environment. Uneven distribution, simply put, is stronger contrast. In our life, there are bare light sources in schools, offices, private houses, etc. The bare light source has high brightness, which interferes with people's life and work to a certain extent. Especially in places where the intensity of work is high, such as industrial plants, many workers will experience glare and other phenomena, which will directly affect the labor efficiency of workers and human visual health to a certain extent, ...
