Description
Technical Field
The invention belongs to the technical field of paint preparation, and particularly relates to a high-temperature-resistant anti-seismic anticorrosive paint and a preparation method thereof.
Background
Sonochemistry is an interdisciplinary discipline that utilizes ultrasound to enhance chemical reactions and enhance chemical effects. As an external field strengthening means, the unique action effect of the ultrasonic wave has good promotion effect on processes such as metal leaching, extraction, ion exchange and the like in hydrometallurgy. However, the hydrometallurgical process is often carried out in an environment with strong acid, strong alkali and strong oxidizing property, most of the traditional ultrasonic generators are made of iron alloy materials, and the ultrasonic generators directly acted on the system are severely corroded, so that the ultrasonic generators are difficult to work in the environment. Therefore, the anti-corrosion operation of ultrasonic waves is extremely important. However, the protection effect of the existing anticorrosive paint on the market on ultrasonic waves is quite limited, and the high-frequency vibration generated by the ultrasonic waves during working can cause the coating to fall off, so that the service life of the coating is seriously shortened. If the elastic coating is used, the mechanical action and cavitation effect of the ultrasonic wave in the system can be weakened, and the strengthening action of the ultrasonic wave in hydrometallurgy is greatly reduced. The cavitation effect of ultrasonic wave can generate instantaneous high temperature, and the high temperature resistance degree of the coating is also required. Therefore, a novel anticorrosive paint is needed to ensure that the ultrasonic generator can work in environments with strong acid, strong alkali and strong oxidizing property.
CN113831833a discloses a preparation method of an anticorrosive polyurethane metal coating, which adopts additives such as hydroxyethyl methacrylate, isooctyl acrylate and the like to improve the crosslinking density of the system, but the anticorrosive performance is poor and can not work in a strong acid-alkali solution; CN101914343a discloses an aqueous polyurethane coating modified with an organosiloxane, but its adhesion properties are poor and cannot work in high frequency vibration environments.

According to the invention, the crosslinking density of the system is improved through the crosslinking reaction of the amide and the carbon-carbon double bond, and the mechanical property of the coating is improved by the fluorenyl epoxy resin; meanwhile, the alkali-free glass fiber improves the toughness of the system and further improves the crosslinking performance of the coating, so that the coating can work under high-frequency vibration and high-pH environments. Compared with the traditional coating, the coating has stronger acid-base corrosion resistance and proper rigidity and toughness, and can cope with the working environment of long-time high-frequency vibration.
