Problems solved by technology

However, although the existing corrosion-resistant coatings can avoid the erosion of harmful substances such as oxygen, salt, and water vapor, they are not resistant to ultraviolet rays, are prone to chalking, softening when exposed to heat, and poor physical properties of low molecular weight. , does not have hydrophobic properties, it is difficult to use in high humidity or water for a long time, and the coating film will oxidize with oxygen in a dry environment to cause embrittlement, which will cause delayed cracks and shorten the service life; in addition, the coating formed after coating Corrosion resistance is poor, after long-term use, it is easy to cause wear and damage of the surface coating

Abstract

The invention discloses a self-cleaning nano material with high weather fastness and a preparation method thereof, and belongs to the technical field of coating. The nano material comprises, by weight, 29-65% of vinyl ester unsaturated polyester resin, 5-35% of nano silicon nitride, 3-33% of nano aluminum nitride, 2-32% of nano titanium dioxide, 6-34% of nano zinc phosphate, 1-19% of nano active calcium carbonate, 1.5-18% of nano wollastonite, 0.6-19% nano precipitated calcium carbonate and 1-18% of nano aluminum silicate. The vinyl ester unsaturated polyester resin is uniformly dispersed in proportion to other components, then an additive is added, and the mixture is uniformly stirred and dispersed and is qualified in detection. The nano material has better hydrophobicity, thereby effectively improving dust adhesion resistance of the coating film, improving stain resistance and self-cleaning ability of the coating film, and allowing the coating film to have good self-cleaning performance and high weather fastness.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a self-cleaning nano material with high weather resistance and a preparation method thereof. Background technique [0002] In order to prevent corrosion, large steel structures such as ships, land structures, and bridges are generally subjected to anticorrosion coating using a corrosion-resistant paint composition. Corrosion-resistant coatings must not only be able to withstand the erosion of harmful substances, but also have the function of isolating harmful substances from the base material. For example, in the field of ships, due to the long-term exposure of ships to marine atmosphere and mist or seawater and other sodium chloride-containing water media, such as the bottom area of ​​the ship submerged in seawater, and the waterline area where seawater alternates between wet and dry and contains sufficient oxygen. , the freeboard area and deck area that are vulnerable to coll...
