Abstract

The invention relates to an electrostatic spraying type high abrasion-resistant powder coating and a preparation method thereof. The electrostatic spraying type high abrasion-resistant powder coating is prepared from the following raw materials in parts by weight: 45 to 95 parts of polyurethane, 5 to 25 parts of hydroxy acrylic resin, 1 to 5 parts of epoxy resin, 5 to 15 parts of multiwall carbon nanotube, 2 to 8 parts of titanium dioxide, 1 to 4 parts of aluminum nitride, 5 to 15 parts of mica powder, 5 to 10 parts of talcum powder, 10 to 30 parts of titanium dioxide, 1 to 20 parts of pigment filler, 0.5 to 2 parts of dibutyltin dilaurate, 0.5 to 3 parts of benzoin, 1 to 3 parts of flatting agent, 0.1 to 1 part of anti-precipitating agent, and 2 to 40 parts of curing agent. The electrostatic spraying type high abrasion-resistant powder coating has the advantage that at the premise of ensuring good conductivity of the powder coating, the corrosion-resistant property of the coating is greatly improved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an electrostatically sprayable high-corrosion-resistant powder coating and a preparation method thereof. Background technique [0002] Oil storage tanks are widely used in oil depots, refineries and oil fields. Because crude oil contains some corrosive impurities, such as inorganic salts, sulfides, nitrides, etc., although these impurities are small in content, they are very harmful to corrosion. In addition, the crude oil imported by many companies from the Middle East is deteriorating day by day, showing a trend of high acid, high sulfur, and high water content, which aggravates the corrosion in the oil storage tank. In order to prolong the service life of the oil storage tank and prevent accidents caused by corrosion, it is necessary to carry out anti-corrosion treatment on the inner wall of the oil storage tank. Coating anti-corrosion is a cheap and effective anti-corrosion...
