Embodiment 1

[0040] Prepare 1000g of the bottom surface of the present invention in one water-based anti-corrosion coating, realize by following process: Add 2.0g dispersant, 1.76g defoamer, 4.62g pH regulator in 192.3g water successively and stir 20min with 500rmp low speed with disperser, make dispersant Distribute evenly in water. Add 100.00g of kaolin, 25.00g of modified zinc phosphate and 50.00g of red iron oxide into the solution, stir with a disperser at a high speed of 1000rmp for 30 minutes, reduce the dispersion rate after the dispersion is uniform, add 589.55g of styrene-acrylic emulsion, and add film-forming 27.98g of additives, 4.98g of anti-flash rust agent and 3.74g of thickener were stirred at 500rmp at a low speed for 10 minutes to make the viscosity reach 100-105KU, and finally 3g of defoamer was added to obtain the bottom-surface-integrated water-based anti-corrosion coating.

Embodiment 2

[0042] Prepare 1000g of the bottom surface of the present invention in one water-based anti-corrosion coating, realize by following process: Add 2.0g dispersant, 1.76g defoamer, 4.62g pH regulator in 192.3g water successively and stir 20min with 500rmp low speed with disperser, make dispersant Distribute evenly in water. Add 100.00g of kaolin, 50.00g of modified zinc phosphate and 50.00g of red iron oxide into the solution, stir with a disperser at a high speed of 1000rmp for 30 minutes, reduce the dispersion rate after the dispersion is uniform, add 559.62g of styrene-acrylic emulsion, and add film forming after the dispersion is uniform 27.98g of additives, 4.98g of anti-flash rust agent and 3.74g of thickener were stirred at 500rmp at a low speed for 10 minutes to make the viscosity reach 100-105KU, and finally 3g of defoamer was added to obtain the bottom-surface-integrated water-based anti-corrosion coating.

Embodiment 3

[0044] Prepare 1000g of the bottom surface of the present invention in one water-based anti-corrosion coating, realize by the following process: add 2.25g dispersant, 1.76g defoamer, 4.62g pH regulator in 199.94g water successively and stir 20min with disperser at 500rmp low speed, make dispersant Distribute evenly in water. Add 100.00g of kaolin, 75.00g of modified zinc phosphate and 50.00g of red iron oxide into the solution, stir with a disperser at a high speed of 1000rmp for 30 minutes, reduce the dispersion rate after the dispersion is uniform, add 528.3g of styrene-acrylic emulsion, and add film forming after the dispersion is uniform 26.41g of additives, 4.98g of anti-flash rust agent and 3.74g of thickener were stirred at 500rmp at a low speed for 10 minutes to make the viscosity reach 100-105KU, and finally 3g of defoamer was added to obtain the bottom-surface-integrated water-based anti-corrosion coating.

Abstract

The invention discloses a bottom unified aqueous anticorrosive paint and its preparation method. the paint is composed of the following ingredients, by weight, 15-30% of water, 0.1-0.5% of a dispersant, 0.4-0.8% of an antifoaming agent, 2.5-25% of modified zinc phosphate, 5-25% of iron oxide red or mica iron oxide, 5-25% of a body filler, 40-70% of a film-forming emulsion, 0.1-1.5% of a thickening agent, 1-4% of a film-forming auxiliary agent and 0.2-1.5% of a flash-rust inhibitor. According to the bottom unified aqueous anticorrosive paint, each ingredient with specific weight percentage interacts with each other. Thus, comprehensive performance of the paint is raised, and in particular, anticorrosive performance of the paint is excellent. The paint is environmentally friendly. Problems of heavy odor, high pollution and the like existing in a traditional oil paint are solved. Meanwhile, each anticorrosion index is guaranteed. The product has simple preparation and construction technologies, is easy to carry out, is easy for large-scale industrial production, and has a wide application prospect.

Description

technical field [0001] The invention relates to the field of water-based anti-corrosion paint and its preparation, in particular to a bottom-surface-integrated water-based anti-corrosion paint and a preparation method thereof. Background technique [0002] Metal materials occupy an important position in the field of materials due to their excellent mechanical properties and process properties, but metal corrosion has also caused huge losses to human society, such as storage and transportation equipment made of metal materials, petrochemical equipment, steel structure workshops, storage roofs and other facilities , due to long-term chemical or electrochemical action and corrosion damage, resulting in a large number of economic losses. Aiming at the problem of metal corrosion, a variety of technologies can be used to protect, slow down or prevent metal corrosion. The most effective and common method is to coat the metal surface with an anti-corrosion coating to isolate the cor...
