Problems solved by technology

According to the above preparation method, there are still a large number of nanoparticles covered and sealed by pigments and fillers and film-forming polymers after the coating is formed into a film, resulting in the problem that its nano-efficacy cannot be exerted.
Therefore, at present, my country's nanocomposite coatings are still in the stage of unstable function and quality, poor practicability, and most of them are research types.
[0004] Looking at the existing technologies for making nano-composite functional coatings, there are problems with the surface dispersion and stability of nano-functional powders, especially the problems of nano-coating and sealing, resulting in poor efficacy, low utilization rate and unstable quality of nano-materials.

Component A is composed of functional complementary nano TiO2,ZnO,SiO2 composite material(1.0-5.0%),film solution silicasol(5.0-10.0%),film forming additive polymer polyvinyl alcohol(500-1000ppm) and water, Ph 7.5-9.0.Component B is composed of resin base material, pigment, additives and water, Ph 8.5-9.5.The invention overcomes low utilization rate, hard dispersion and bad function of general nano material, and having high nano efficiency, and low cost.

Description

technical field [0001] The invention belongs to the field of inorganic materials and nanometer technology, and relates to a manufacturing and construction method of a packaged nanocomposite functional paint. Background technique [0002] At present, the general method of manufacturing nano-coatings can be divided into two categories: (1) nano-structured coatings. Nano-structured coatings are prepared by a special process to prepare nano-emulsions, which are prepared by mixing and mixing nano-polymer emulsions (base materials) with dispersed and stable nano-scale pigments and fillers, additives, etc. The cost of this type of coating is high, and there are still problems in the dispersion and stabilization of nano-pigment filler slurry at high concentrations. (2) Nano-composite functional coatings. Nano-composite functional coatings are made by adding nano-powder or its dispersion liquid as a functional component to ordinary pigment and filler slurry for high-speed sand grin...
