Embodiment 1
[0017] 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 system temperature 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 and 40g octadecanoic acid lithium salt promptly get a kind of water-based inorganic anticorrosion paint that adds octadecanoic acid lithium salt.
Embodiment 2
[0019] Pour 500g of sodium silicate solution into a heatable container and heat it slowly. When the temperature of the solution reaches 65°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 550 mesh ultrafine zinc powder, and finally add 80g of MgCl 2 Aqueous solution and 120g octadecanoic acid lithium salt promptly get a kind of water-based inorganic anticorrosion paint that adds octadecanoic acid lithium salt.
Embodiment 3
[0021] Pour 1500g of sodium silicate solution into a heatable container and heat it slowly. When the temperature of the solution reaches 75°C, add 750g 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 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 and 200g octadecanoic acid lithium salt promptly get a kind of water-based inorganic anticorrosion paint that adds octadecanoic acid lithium salt.
