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.

Abstract

The invention relates to water-borne inorganic anti-corrosive paint added with lithium stearate serving as a stabilizer. A preparation method of the paint comprises the steps that an appropriate amount of sodium silicate solution is taken and poured into a vessel which can be heated, slow heating is conducted through a heat source, when the temperature rises to about 70 DEG C, silicone acrylic emulsion is added into the vessel, heating is stopped after the mixture is thoroughly mixed, a titanate coupling agent and zinc powder are sequentially added, stirring is accelerated for mixing, a MgC12 aqueous solution and the lithium stearate serving as a stabilizer are added at last, and the water-borne inorganic anti-corrosive paint added with the lithium stearate is obtained after the mixture is evenly mixed. The prepared paint is good in stability performance, the preparation technology is simple, and the water-borne inorganic anti-corrosive paint added with the lithium stearate has better application prospect.

Description

technical field [0001] The invention relates to an anti-corrosion paint and a preparation method thereof, in particular to a water-based inorganic zinc-rich anti-corrosion paint added with stearate and a preparation method thereof, belonging to the field of paint chemical industry. Background technique [0002] Steel is widely used in our lives, such as the automobile industry, manufacturing industry, construction industry, transportation industry and other industries, but the corrosion resistance of steel is poor, and corrosion resistance is very important for steel. According to statistics, every year due to corrosion The loss accounts for about 10%-20% of the annual output. Corrosion is generally caused by chemical or electrochemical multiphase reactions between the metal surface and the medium. After corrosion, the mechanical properties such as strength and toughness of the steel material will be significantly reduced, and the metal will be damaged. The geometric shape o...
