Abstract

The invention reveals an acrylic finish coat, which is composed of a component A and a component B, wherein the component A comprises the following components in percentage by mass: 20-50% of high-molecular-weight acrylic resins, 30-40% of coal pitch, 6-15% of mixed solvent, 10-20% of filler, 1-5% of pigment and 1-5% of additive; and the component B is a curing agent. In the construction, the component A and component B are mixed in a dosage ratio of (6-7): 1 to obtain the acrylic finish coat. The acrylic finish coat revealed by the invention has good water resistance, acid and alkali chemical resistance and weather resistance, good corrosion resistance and low possibility of aging; compared with the prior art, the acrylic finish coat revealed by the invention also has excellent fullness and high luster; and at the same time, the acrylic finish coat has low cost because of readily available raw materials, and can meet the dual requirements of the market on the performance and appearance of anti-corrosion coating.

Description

technical field [0001] The invention relates to the technical field of anticorrosion coatings, in particular to an acrylic topcoat. Background technique [0002] Among all kinds of anti-corrosion technologies and measures, the use of paint anti-corrosion is the simplest and most effective method, which is widely used. At present, the most used anti-corrosion coating is fluorocarbon topcoat, which has many advantages such as strong adhesion, good corrosion resistance and anti-aging performance, but this kind of fluorocarbon topcoat is expensive and expensive, and cannot meet the requirements The market demands high gloss. There are also some paints used for spraying on metal surfaces in the prior art, but the effect of spraying is not ideal, and there are defects such as poor appearance quality, easy scratches, easy wear damage, dull luster, and poor outdoor weather resistance, which affects the metal plate. Appearance quality and appearance image. Therefore, the developme...
