Problems solved by technology

The existing water-based paints on the market have the characteristics of difficulty in dispersion and poor storage stability, and corrosion often occurs during construction and application in winter
In addition, the current common metal water-based paints have poor hardness, the anti-corrosion and anti-rust function cannot last long, and the weather resistance is poor. In winter, the temperature is low, it is easy to fall off, and the better anti-rust effect cannot be achieved; the light resistance is poor, and it is easy to pulverize. Safety cannot be guaranteed; there may be toxic substances that may cause harm to the human body during use

Description

technical field [0001] The invention relates to a water-based paint, in particular to a water-based metal paint and a preparation method thereof. Background technique [0002] As an environmentally friendly and convenient metal paint, water-based metallic paint has been used more and more widely in recent years, and its cost is low. It has been more and more respected and developed rapidly. The existing water-based paints on the market have the characteristics of difficulty in dispersion and poor storage stability, and phenomena such as corrosion often occur during construction and application in winter. In addition, the current common metal water-based paints have poor hardness, the anti-corrosion and anti-rust function cannot last long, and the weather resistance is poor. In winter, the temperature is low, it is easy to fall off, and the better anti-rust effect cannot be achieved; the light resistance is poor, and it is easy to pulverize. Safety cannot be guaranteed; ther...
