Abstract

Disclosed is a waterproof nanometer anticorrosive coating. The waterproof nanometer anticorrosive coating is prepared from, by mass, 28-39% of modified epoxy resin, 18-28% of a water repellent agent, 8-13% of hydrophobic nano-silica, 8-14% of glass flakes, 3-7% of isophthalic acid ester, 5-14% of diethanol amine, 2-3% of bentonite, 8-15% of nanometer calcium oxide and 5-8% of polyaniline. The water repellent agent is an organic silicon water repellent agent or a wax water repellent agent or a water-based nanometer water repellent agent. The invention further discloses a preparation method of the nanometer anticorrosive coating. The method comprises the three steps totally. The nanometer anticorrosive coating has the good waterproof performance and anticorrosive performance, is high in compactness and has the higher stability and reliability. The waterproof nanometer anticorrosive coating can be applied to seaborne facilities, industrial buildings and various mechanical devices, and has the wide development prospect.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion coatings, and in particular relates to a waterproof nano anti-corrosion coating and a preparation method thereof. Background technique [0002] There are mainly two types of coatings used in offshore facilities, civil construction, transportation machinery, etc.: waterproof coatings and anti-corrosion coatings. The waterproof coating has the function of waterproof and anti-seepage, and the anti-corrosion coating has the function of anti-corrosion. [0003] However, in actual use, it is often required that the coatings used have both waterproof and anti-corrosion functions. In offshore installations, in order to prevent seawater from penetrating into electronic devices, all parts must be waterproof, and seawater is corrosive to a certain extent, so the coating must have anti-corrosion function. In recent years, the phenomenon of acid rain in some areas has become more and more serious, whi...
