Problems solved by technology

[0003] There are two main reasons why the surface of the powder coating is easy to accumulate dust and is not resistant to pollution: (1) The powder coating is easy to be charged with static electricity, and the polymer resin as the matrix has strong electrical insulation. and other reasons to generate and accumulate static electricity, and a small static charge is enough to generate a high static voltage, resulting in electrostatic dust collection; (2) The surface of the powder coating still has more polar groups, which is easy to cause air pollution. Adsorption of polar dust, resulting in polar sticky dust
[0004] The existing industrial and practical antistatic polymers are mainly surfactant products. This type of surfactant contains both hydrophilic and lipophilic groups. The lipophilic group combines with the resin to produce a similar "water film" in the air layer. ", to reduce static electricity, but on the one hand, the polar surface layer produced by this scheme is easy to stick to dust, and on the other hand, the durability of the coating is poor
While super-hydrophobic coatings are more common in liquid coatings, solid coatings often use surface treatment to spray a layer of hydrophobic layer again to achieve the purpose of hydrophobicity, but their service life is short

Description

technical field [0001] The invention relates to the field of powder coatings, in particular to a dust-proof and anti-fouling powder coating, a preparation method and application thereof, and a dust-proof and anti-fouling product. Background technique [0002] Powder coatings have a completely different form from conventional liquid coatings, which exist in the state of fine powder. Because no solvent is used, it is called powder coating. Powder coatings mainly have the characteristics of solvent-free, pollution-free, recyclable, environmentally friendly, energy-saving and resource-saving. [0003] There are two main reasons why the surface of the powder coating is easy to accumulate dust and is not resistant to pollution: (1) The powder coating is easy to be charged with static electricity, and the polymer resin as the matrix has strong electrical insulation. and other reasons to generate and accumulate static electricity, and a small static charge is enough to generate a ...
