Abstract

The invention relates to a coating with performances of self-cleaning, heavy corrosion protection and super weather resistance. The coating with performances of self-cleaning, heavy corrosion protection and super weather resistance comprises an epoxy resin particle system which consists of epoxy resin and curing agent A, and a fluorocarbon resin particle system which comprises fluorocarbon resin, curing agent B and TiO2 nanometer particles. The ratio (weight in parts) of the epoxy resin particle system to the fluorocarbon resin particle system is 4-1:1-4. The self-cleaning powder coating with performances of heavy corrosion protection and super weather resistance disclosed by the invention has phase separation during the curing process to form a fluorocarbon face and an epoxy bottom layer, TiO2 nanometer particles only exist in the fluorocarbon face, and photocatalysis decomposition is prevented under the action of TiO2 due to the high chemical stability of fluorocarbon, so that the powder coating has good performances of self-cleaning, heavy corrosion protection and super weather resistance.

Description

technical field

[0001] The invention relates to a self-cleaning heavy-duty anti-corrosion super-weather-resistant powder coating and a preparation method and application thereof, belonging to the field of functional powder coatings. Background technique

[0002] With the rapid economic development in the last ten years, infrastructure construction has achieved a gratifying situation of rapid development, but the problem of stains on the surface of buildings has not been well resolved. Severe stains on the surface of buildings will lead to poor landscape effects, a decline in asset value, damage to the image of the government and the owner unit, and the cleaning work is time-consuming and laborious. Individual cleaning work such as highway guardrails and other traffic facilities is difficult to carry out. In the field of coatings, it is the mainstream understanding that hydrophobic coatings are not easy to adhere to stains. On this basis, many stain-resistant products have be...
