Problems solved by technology

Due to the large particles (15-45μm) of ordinary zinc phosphate, its shape is brick-shaped, the surface area is small, the dispersion is poor, and the solubility is low and the hydrolysis is poor, the anti-rust activity is insufficient, and the speed of forming an effective protective film is too slow. In alkaline water-based primers, the problem of "flash rust" cannot be overcome, and the anti-rust performance cannot reach the level of traditional zinc chrome yellow, and it is difficult to completely replace traditional harmful anti-rust pigments

Abstract

The invention provides anticorrosive paint and a preparation method thereof. The anticorrosive paint is prepared from components in percentage by total mass of the paint as follows: 5.0%-35.0% of nano-modified phosphate, 1.0%-20.0% of nano aluminum triphosphate and 30.0%-80.0% of water-based fluorocarbon resin. According to the anticorrosive paint, toxic-free molybdenum-modified zinc phosphate and polymeric aluminum phosphate subjected to micronization treatment are taken as anti-rust pigments, and the paint system is ensured to be toxic-free. A water-based fluorocarbon resin system is selected, a paint film is ensured to have high transparency and compactness as well as excellent weather fastness, wear resistance, corrosion resistance and low-temperature resistance, and long-time operation of equipment can be guaranteed. The paint coating has hydrophobic and oleophobic properties, is not sticky or is anti-sticking and is easy to clean.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to an anti-corrosion coating and a preparation method thereof. Background technique [0002] Stainless steel is a silver-white alloy steel with excellent corrosion resistance, wear resistance, toughness and processability. It is widely used in aerospace, marine, pharmaceutical, nuclear energy, petrochemical and other industries. [0003] The main reason for the increasingly wide application of stainless steel is based on the characteristics of this series of materials: corrosion resistance. The corrosion resistance of stainless steel in some environments is related to its passivation performance. Usually when the chromium content reaches 12%, the alloy can achieve complete self-passivation ability. The passivation ability of the alloy determines the resistance of stainless steel to a certain extent. corrosion. [0004] The function of stainless steel passivation treatm...
