Problems solved by technology

Water-based inorganic zinc-rich paint has the advantages of no odor, non-flammable, non-explosive, and no environmental pollution due to its absence of organic solvents. However, due to less solvent and low wettability, the adhesion is not as good as the corresponding solvent-based paint, and zinc powder In the coating, due to the poor wettability of zinc powder, zinc powder is easy to settle, which affects product quality

Embodiment 1

[0026] Pour 200g of sodium silicate solution into a heatable container and heat it slowly. When the temperature of the solution reaches 60°C, add 100g of silicon acrylic emulsion dropwise into the container and keep stirring. After the dropwise addition, stop Heating, after the temperature of the system drops to room temperature, add 30g of titanate coupling agent to the container, and increase the stirring speed, then add 600g of 500 mesh ultrafine zinc powder, and finally add 30g of MgCl 2 Aqueous solution, 20g of calcium stearate and 20g of dodecyl glycol amide are fully stirred to obtain a stable performance anti-corrosion paint.

Embodiment 2

[0028] Pour 500g of sodium silicate solution into a heatable container and heat it slowly. When the temperature of the solution reaches 70°C, add 200g of silicon acrylic emulsion dropwise into the container and keep stirring. After the dropwise addition, stop Heating, after the system temperature drops to room temperature, add 100g of titanate coupling agent to the container, and increase the stirring speed, then add 1000g of 600 mesh ultrafine zinc powder, and finally add 80g of MgCl 2 Aqueous solution and 60g of calcium stearate and 60g of dodecyl glycol amide are fully stirred to obtain a kind of anticorrosion paint with stable performance.

Embodiment 3

[0030] Pour 1500g of sodium silicate solution into a heatable container and heat it slowly. When the temperature of the solution reaches 80°C, add 750g of silicon acrylic emulsion dropwise into the container and keep stirring. After the dropwise addition, stop Heating, after the temperature of the system drops to room temperature, add 150g of titanate coupling agent to the container, and increase the stirring speed, then add 2550g of 600 mesh ultrafine zinc powder, and finally add 150g of MgCl 2 Aqueous solution, 100g of calcium stearate and 100g of dodecyl glycol amide are fully stirred to obtain a stable anti-corrosion paint.

Abstract

The invention discloses a calcium-stearate / amide-modifier-added anticorrosive paint which is composed of sodium silicate, superfine zinc powder, a silicone-acrylic emulsion, a titanate coupling agent, a MgCl2 water solution, barium stearate and dodecyl diol amide. The composite stable modifier is added to improve the wettability of the system and enhance the solubilization property, thereby finally improving the stability of the paint. The paint has the advantages of simple preparation technique, favorable stability and low cost, and has favorable application prospects.

Description

technical field [0001] The invention relates to an anti-corrosion paint, in particular to an anti-corrosion paint added with a stearate and a dodecyl glycol amide modifier and a preparation method thereof, belonging to the field of paint synthesis. Background technique [0002] With the improvement of anti-corrosion requirements for steel, zinc-rich anti-corrosion paint has received widespread attention. Zinc-rich paint contains a large amount of zinc powder, and the zinc particles are in close contact with the surface of the steel. The potential of zinc is more negative than that of iron, so In the electrolyte solution, zinc atoms easily lose electrons and become anodes, while iron is a cathode. In the anode area, zinc is corroded due to the loss of electrons, and in the cathode area, the steel surface continuously obtains electrons, thereby being protected. When a part of the coating film is damaged, the base metal is exposed, and the corrosion current can flow to the exp...
