Abstract

The invention relates to a preparation method of an anticorrosion paint, in particular to a preparation method of a water-based environmentally-friendly anticorrosion paint, which is mainly used for solving the technical problems that the product performance cannot be brought into full play, the comprehensive product performance cannot be reflected to the maximum extent due to the selecting and the matching of a raw material structure and the performance price ratio and the like. The method comprises the following steps of: adding water into a dispersion machine, starting the dispersion machine at a low speed and adding a dispersant, a flash rust agent, a multifunctional aid, a defoaming agent and a preservative for performing low-speed dispersing; adding a composite phosphate ferrotitanium inhibitive pigment, zinc phosphate, iron red, calcite and sericite for performing low-speed dispersing; switching to a medium-speed gear, adding a defoaming agent, silica sol, alcohol ester-12, an anti-freezing agent and a flatting agent for performing high-speed dispersing; and adding an emulsion, dispersing, adding a pH value regulating agent for adjusting the pH value, slowly adding a thickening agent and an inhibitor, verifying viscosity, filtering and canning to obtain a finished product.

Description

technical field [0001] The invention relates to a preparation method of an antirust paint, in particular to a preparation method of a water-based environment-friendly antirust paint. Background technique [0002] With the development of the national economy and the improvement of people's living standards, the application scope of coatings has been continuously expanded, people's awareness of environmental protection has been enhanced and environmental protection regulations have become increasingly strict, and the requirements for coatings are getting higher and higher. The world's sustainable development of environmental protection regulations continues to strengthen, and the general trend of promoting the coating industry to develop in an environmentally friendly direction will not change. [0003] According to data, in the United States, Japan, Canada and other countries, the direct economic loss caused by corrosion accounts for about 1%-4% of the total national economic...
