Abstract

The invention relates to an anti-corrosion and high-gloss paint and a preparation method and use thereof. The paint contains a basic paint and an organic silicon resin, which are in a volume ratio of 1: (0.5-4). According to the preparation method, the basic paint and the organic silicon resin are mixed to prepare the anti-corrosion and high-gloss paint. According to the method, zirconate, acetylacetone and isopropanol form a three-dimension crosslinking structure which facilitates the modest progress of the reaction, and allows the reaction speed to be better controlled compared with the single use of zirconate as a catalyst. The paint undergoes a cross-linking reaction with the active groups in a substrate and the paint to form bridges, which increases molecular weight. The paint and the substrate form strong adhesion under the action of the bridges, and the water, solvent and boiling resistance of the paint is improved together with the drying speed and surface gloss of films.

Description

【Technical field】 [0001] The invention relates to the technical field of functional coatings, in particular to an anti-corrosion and high-gloss coating and its preparation method and application. 【Background technique】 [0002] The particle size of the pigment in the paint and its dispersibility in the base material will affect the gloss of the paint film. The finer the pigment fineness, the better the uniformity of dispersion in the base material, which helps to form a flat and smooth paint film. The pigment-to-base ratio in the paint affects the gloss of the paint film. The gloss decreases due to the weakening of the specular reflection by the pigment particles in the paint film, and the gloss gradually decreases with the increase of the pigment volume concentration (P.V.C). When the pigment-base ratio is constant, the greater the oil absorption of the pigment, the lower the gloss. Different colors of pigments have different degrees of light absorption and reflection.
