Problems solved by technology

[0002] Anti-corrosion mainly plays the role of beautifying the appearance and anti-corrosion. Commonly used anti-corrosion coatings are mainly organic solvent coatings, and do not have hydrophobic properties. Traditional anti-corrosion coatings generally use epoxy resin, polyurethane resin, polyester resin or alkyd resin as the polymer matrix. , use the high molecular weight of the polymer to prevent corrosion of the cable metal material, and add graphite powder, titanium dioxide, iron red and other fillers to play the role of pigments and anti-corrosion fillers. Since the wires are generally used outdoors, they are in a dusty environment. In a highly polluted environment, it is very easy to get dirty, which affects the conductivity and service life
[0003] Conventional anti-corrosion coatings play an anti-corrosion effect on metals under normal conditions and protect the service life of non-ferrous metals; however, the existing anti-corrosion coatings have poor anti-corrosion effects, and often crack and fall off after a period of use. Repeated coating is required to achieve the anti-corrosion effect, the cost is high, and it cannot meet the needs of users
