Abstract

The invention relates to the technical field of coatings, and provides a high-gloss black anticorrosive coating as well as a preparation method and spraying method thereof. The high-gloss black anticorrosive coating comprises a base material and a curing agent; and the base material comprises the following components, in parts by weight: 80-90 parts of organic resin, 0.5-1 part of an antifoaming agent, 1-2 parts of carbon black, 1-1.5 parts of a dispersing agent, 0.5-1 part of fumed silica and 8-11 parts of an organic solvent, wherein the carbon black can change the color of the coating, the fumed silica can prevent excessive precipitates from being formed, the dispersing agent can accelerate diffusion of the carbon black and prevent a precipitate from being formed, the content of the organic rubber is higher, so that the bonding performance of the coating is improved, and the coating has stronger adhesion, longer protection time for a metal and longer anticorrosion time. According tothe metal component provided by the invention, at least a part of the surface is provided with the high-gloss black anticorrosive coating, and the formed anticorrosive coating layer has a good anticorrosion effect and high anticorrosion stability.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-gloss black anti-corrosion coating, a manufacturing method and a spraying method thereof. Background technique [0002] Metals and their alloys are important engineering materials, widely used in construction, transportation, industry, marine, aviation, aerospace and other fields. They play an important role in national economy and social progress. Corrosion of metals is a common phenomenon; it undergoes a series of electrochemical reactions in an oxygen-containing environment, thereby deteriorating the performance of metal components. [0003] In recent years, due to the negative impact of metal corrosion on the environment, economic losses, etc., people have paid more and more attention to it. However, the existing protective coatings cannot play a good protective role due to the selection of materials. Bring inconvenience to people's use. [0004] Therefore, it is n...
