Problems solved by technology

[0004] However, because nano-mesoporous titanium dioxide is very small, its specific surface area is large, its surface free energy is high, and its intermolecular and electrostatic attraction are also quite high. Its dispersion into the base material is the key technology for the application of nano-mesoporous titanium dioxide in coatings

Description

technical field [0001] The invention relates to the field of coatings, in particular to a nanometer mesoporous titanium dioxide anticorrosion coating. Background technique [0002] With the continuous progress of nanomaterials science, the excellent properties of nanocomposite coatings have attracted increasing attention. According to the nano-size effect and huge specific surface area characteristics of nanoparticles, evenly dispersing nanoparticles in traditional anti-corrosion coatings to make nano-composite coatings can greatly improve the excellent performance of anti-corrosion coatings. [0003] Nano-mesoporous titanium dioxide is an excellent photocatalytic inorganic antibacterial material, non-toxic, tasteless, and non-irritating. Applying it to coatings and keeping them in a nano-scale state in the coating can improve the poor weather resistance and easy-sticking of existing coatings. Pollution and other shortcomings. [0004] However, because nano-mesoporous tita...
