Problems solved by technology

[0003] Water-based inorganic zinc-rich coatings have the advantages of no odor, non-flammable, non-explosive, and no environmental pollution due to their absence of organic solvents. However, due to the lack of solvents, the wettability of zinc powder is not good, and zinc powder is easy to settle, which affects product quality.

Embodiment 1

[0024] Pour 50g of potassium silicate solution and 50g of sodium silicate solution into a container for mixing respectively, and heat the mixture, the heating temperature is controlled at about 50°C, and it is stirred continuously with a stirrer. During the stirring process, slowly add 300g of silica sol dropwise, after the dropwise addition, add 30g of dioctyl phosphate acyloxy titanate and 20g of sodium dodecylbenzenesulfonate in the container, and increase the Stirring speed, stop heating after 5 minutes, and when the temperature drops to room temperature, add 250g of silicon acrylic emulsion, and finally add 300g of 700 mesh zinc powder, continue stirring evenly to get a solubilized modified zinc-rich anti-corrosion coating .

Embodiment 2

[0026] Pour 70g of potassium silicate solution and 70g of sodium silicate solution into a container for mixing, and heat the mixture. The heating temperature is controlled at about 60°C, and it is stirred continuously with a stirrer. During the stirring process, slowly add 300g of silica sol dropwise, after the dropwise addition, add 35g of dioctyl phosphate acyloxy titanate and 25g of sodium dodecylbenzenesulfonate in the container, and increase the Stirring speed, stop heating after 5 minutes, when the temperature drops to room temperature, add 300g of silicon acrylic emulsion, and finally add 200g of 700 mesh zinc powder, continue stirring evenly to get a solubilized modified zinc-rich anti-corrosion coating .

Embodiment 3

[0028] Pour 100g of potassium silicate solution and 100g of sodium silicate solution into a container for mixing, and heat the mixture. The heating temperature is controlled at about 70°C, and it is stirred continuously with a stirrer. During the stirring process, slowly add 200g of silica sol dropwise, after the dropwise addition, add 70g of dioctyl phosphate acyloxy titanate and 30g of sodium dodecylbenzenesulfonate in the container, and increase the Stirring speed, stop heating after 5 minutes, and when the temperature drops to room temperature, add 200g of silicon acrylic emulsion, and finally add 300g of 700 mesh zinc powder, continue stirring evenly to get a solubilized modified zinc-rich anti-corrosion coating .

Abstract

The invention discloses solubilizing modified anti-corrosion paint added with sodium dodecyl benzene sulfonate and a preparation method thereof. The method comprises the following steps that firstly, a certain amount of potassium metasilicate solution and a certain amount of sodium silicate solution are respectively poured into a container to be mixed and heated; silica sol is added; then, a certain amount of dioctyl phosphate acyloxy titanate and sodium dodecyl benzene sulfonate are added; high-speed uniform stirring is performed; finally, silicon-acrylate emulsion and 700-mesh zinc powder are sequentially added; solubilizing modified zinc-rich anti-corrosion paint is obtained after the continuous uniform stirring.

Description

technical field [0001] The invention relates to a solubilized modified anti-corrosion paint and a preparation method thereof, in particular to a solubilized modified anti-corrosion paint added with a surfactant and a preparation method thereof, belonging to the field of paint processing. Background technique [0002] Metal anti-corrosion coatings are more and more widely used. Ordinary metal anti-corrosion coatings are on the surface of steel to prevent steel corrosion by isolating air, while zinc-rich anti-corrosion coatings can not only isolate air, but also form primary battery protection. Zinc-rich anti-corrosion coatings The standard potential of zinc in the battery is lower than that of steel. When the corrosive medium penetrates, steel and zinc powder form a primary battery. Zinc-rich paints are divided into organic zinc-rich paints and inorganic zinc-rich paints, organic zinc-rich paints commonly used epoxy resin, chlorinated rubber, vinyl resin and polyurethane resi...
