Problems solved by technology

However, due to the particularity of water-based coatings, the salt spray resistance of current water-based anti-rust coatings is not as good as that of oil-based coatings, which is also a major obstacle to the promotion and application of water-based anti-corrosion coatings.

Abstract

The invention discloses high-performance waterborne primer with ultrahigh acidic salt mist resistance and a preparation method thereof. The primer is prepared from raw materials in parts by weight as follows: 20-30 parts of waterborne epoxy resin, 20-30 parts of waterborne amino resin, 5-8 parts of titanium dioxide, 1-3 parts of graphite powder, 6-8 parts of zinc phosphate, 6-8 parts of aluminum triphosphate, 0.5-1 part of ceramic powder, 0.5-2 parts of a silane coupling agent, 8-15 parts of an aid and 10-30 parts of deionized water. The primer has good adhesion force for a substrate and also has excellent physical and mechanical performance and higher hardness, flexibility and wear resistance, a coating can resist acidic salt mist for about 600 h, and the primer has the wide application range and can be applied to various types of metal substrates.

Description

technical field [0001] The invention belongs to the field of paint and its preparation, and in particular relates to a water-based high-performance primer with super acid salt spray resistance and a preparation method thereof. Background technique [0002] Regarding corrosion, before the 1950s, its definition was limited to the corrosion of metals. Since the 1950s, many authoritative corrosion scholars or research institutions tend to define corrosion as the expansion of all materials, but usually refers to the damage of metals. In the production process, if there is chemical corrosion that devours steel in a large area, it is easy to cause the equipment to run, run, drip, leak, etc., which not only pollutes the environment, but also may cause fire, explosion and other dangerous events, which will cause the plant , machinery and equipment damage, resulting in serious accidents. Especially in the case of high temperature and high pressure in the petrochemical production pro...
