Embodiment 1

[0023] Pour 200g of potassium 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 barium stearate promptly get a kind of anticorrosion paint that adds barium stearate.

Embodiment 2

[0025] Pour 500g of potassium 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 barium stearate promptly get a kind of anticorrosion paint that adds barium stearate.

Embodiment 3

[0027] Pour 1500g of potassium 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 barium stearate promptly get a kind of anticorrosion paint that adds barium stearate.

Abstract

The invention discloses a stearic acid metallic soap stabilizer-added antifouling paint. By adding a barium stearate stabilizer in the preparation process of the antifouling paint, namely introducing a loose network thixotropic structure in the paint, the sedimentation phenomenon in the preparation process of the paint is avoided, and the stabilizing property of the paint is improved.

Description

technical field [0001] The invention relates to a metal anticorrosion paint and a preparation method thereof, in particular to a stearate-added anticorrosion paint and a preparation method thereof, belonging to the field of paint chemical industry. Background technique [0002] Many items are prone to various corrosions in the working environment. In order to make the material more durable, a protective layer is often coated on the surface of the material to prevent or delay corrosion. Anti-corrosion paint is used on the surface of objects and can be used A type of paint that protects the interior of objects from corrosion. It is widely used in aviation, ships, chemicals, oil pipelines, bridges and other fields. [0003] Anti-corrosion is very important for metal steel. Steel is widely used in our life, such as automobile industry, manufacturing industry, construction industry, transportation industry and other industries, but the corrosion resistance of steel is poor. Accor...
