Abstract

The invention discloses a water-based high-temperature-resistant anti-rust multifunctional coating. The coating is prepared from the following raw materials in parts by weight: 30-50 parts of siliconemodified acrylic resin, 10-20 parts of high-temperature-resistant pigments, 6-10 parts of aids, 15-30 parts of anti-rust pigments and 15-25 parts of deionized water. Meanwhile, the invention furtherprovides a preparation method of the water-based high-temperature-resistant anti-rust multifunctional coating. The film-forming compactness of the coating during spraying is improved, and the adhesiveforce and toughness are improved to different degrees.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based high-temperature-resistant rust-resistant multifunctional coating and a preparation method thereof. Background technique [0002] The most effective, simple and economical way to slow down the corrosion of steel surface is to apply anti-rust paint on the surface. In order to obtain excellent anti-corrosion performance, the traditional process completely removes the rust on the substrate, and requires the substrate to expose the metallic luster, which is quite heavy work, low production efficiency, high construction cost, and rust dust is extremely harmful to the human body. Therefore, it is necessary to develop a coating that can be directly applied on a certain rusted surface. While reducing the coating cost, it can also simplify the painting process, reduce labor intensity, and reduce the harm of rust to the human body and environmental pollution. [0003] Solve...
