Problems solved by technology

However, solvent-based coatings will emit a large amount of toxic and harmful substances during the manufacturing and construction process, causing huge pollution to the environment. Countries around the world have successively formulated relevant regulations to limit the use of protective coatings for solvent-based engines.

Abstract

The invention provides high temperature-resistant water-based paint for engines and a preparation method thereof, and relates to the technical field of paint. The high temperature-resistant water-based paint is prepared from the following components in parts by mass: 25-45 parts of water-based acrylic resin, 5-25 parts of water-based amino resin, 2-10 parts of water-based silver pulp, 0.5-5 parts of a pigment, 5-15 parts of an assistant and 15-25 parts of deionized water. The high temperature-resistant water-based paint solves the technical problems that the high temperature-resistant paint for engines in the prior art is mainly solvent-based paint which discharges a large quantity of toxic and harmful substances in the manufacture and construction process and causes great pollution to the environment. The high temperature-resistant water-based paint achieves the technical effects of reducing the discharge of toxic and harmful substances, promoting harmonic development of economy and society, providing effective protection for engines and spare parts thereof, prolonging the service life of engines, reducing the use cost and eliminating potential safety hazard.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-temperature-resistant water-based paint for engines and a preparation method thereof. Background technique [0002] The engine and its components are often exposed to high temperature and corrosive media, which makes the engine equipment very easy to corrode and perforate, which brings great hidden dangers to equipment safety, shortens the service life of the engine, and increases the cost of use. In order to prolong the service life of the engine, it is necessary to spray coatings on the surface of the engine and its parts for protection. At present, the protective coatings for engines are mainly high-temperature resistant solvent-based coatings, such as acrylic epoxy paint, one-component acrylic topcoat, acrylic Finish varnish, silicone high temperature paint, etc. However, solvent-based coatings will emit a large amount of toxic and harmful substances during the manuf...
