Due to the poor washing resistance of traditional coatings, the coating will change color and fall off after a short period of time. The glass curtain wall will also bring light pollution, increase the weight of the building, and have potential safety hazards. If traditional cleaning agents are used for cleaning, it will not only pollute The environment also wastes a lot of human resources and water resources
Many self-cleaning coatings currently on the market have relatively simple construction methods and many defects. The most important thing is that their self-cleaning effect is not long-lasting

preparation example Construction
[0034] A kind of preparation method of long-acting self-cleaning coating as claimed in claim 1, comprises the following steps:
[0035] (1) Weigh the materials in the raw material formula according to the above parts by weight;
[0036] (2) Add the resin into the material tank for stirring, while stirring, slowly add raw materials such as dispersant, defoamer, pigment and filler in sequence, after mixing evenly, grind and disperse the slurry to a fineness of 15um;
[0037] (3) Add the leveling agent, active components, and solvents to the slurry in step (2) in sequence, and mix evenly again to obtain a long-lasting self-cleaning coating (component A).
[0038] The long-acting self-cleaning paint of the present invention can be applied in various ways: spraying (air / airless), brushing, roller coating, electrostatic spraying, etc. Taking spraying (with air) as an example, the application process of the long-acting self-cleaning coating of the present invention is briefly descri...

Abstract
The invention provides a long-lasting self-cleaned coating which comprises the following components in parts by weight: 40-60 parts of a resin, 15-30 parts of a pigment filler, 1-5 parts of aids, 2-8 parts of active components, 20-40 parts of a solvent and 5-20 parts of a curing agent, wherein the aids comprise a dispersing agent, a defoaming agent and a leveling agent. The long-lasting self-cleaned coating provided by the invention has surface properties which are greatly different from those of a common coating, and has relatively high surface energy and humidity. If the coating is affected by external factors such as wind, frost, rain and snow, a relatively great amount of antifouling effective components can be slowly released from the coating continuously, and then surface cleaning of the coating is recovered. In different actual use environments, the long-lasting self-cleaned coating can last for 3-5 years or even longer, and can be applied to inner and outer coating of high-speed rains, vehicle stations and carriages, building aluminum profiles, aluminum veneers, metal curtain walls, glass curtain walls, automobiles, solar panels and decoration fields which require surface cleaning and cannot be frequently maintained or are barely maintained.
Description
technical field [0001] The invention relates to the field of petrochemical coatings, in particular to a long-acting self-cleaning coating and a preparation method thereof. Background technique [0002] With the development of society and economy, the living and working standards and requirements are increasing day by day, and the pollution brought by environmental deterioration to human life is becoming more and more serious, especially the pollution of buildings such as building exterior walls and glass curtain walls. High-rise buildings are being eroded more and more seriously, and glass curtain walls and metal curtain walls are favored by architects because of their functional and decorative advantages, but maintaining their cleanliness and beauty is a difficult problem. Due to the poor washing resistance of traditional coatings, the coating will change color and fall off after a short period of time. The glass curtain wall will also bring light pollution, increase the we...
