Problems solved by technology

[0004] Large-scale steel installations and facilities, such as oil storage tanks, iron frames, iron bridges, sluice gates, ships, etc., can only be derusted by hand, which is not only labor-intensive and inefficient, but also difficult to remove rust;
[0005] Small and medium-sized steel parts can be derusted by shot blasting. Although the derusting effect is good, it is subject to various restrictions due to large dust, loud noise, serious environmental pollution and high labor costs.
[0006] With the development of industry, there are more and more projects such as steel bridges and large pipelines. The above rust removal methods are far from meeting the needs of the project. solved problem

preparation example Construction

[0053] The invention also discloses a preparation method of an antirust color paste for water-based industrial coatings, the specific steps are as follows:

[0054] Step 1: Add the stabilizer to deionized water, stir and mix to make a pre-solution;

[0055] Step 2: Add dispersant, humectant, bactericide, acidic complexing agent, conversion agent, and defoamer into the pre-solution, and stir evenly;

[0056] Step 3: Add nano-TiO 2 and carbon black powder, stir;

[0057] Step 4: Add the above-mentioned mixed slurry components into a grinder and grind until a uniform slurry with good fluidity is formed;

[0058] Step 5: adding an appropriate amount of pH regulator to adjust the pH value of the slurry to prepare the antirust color paste for water-based industrial coatings of the present invention.

[0059] In order to further realize the technical effect of the present invention, the stirring time of step 2 is 10-20 minutes, and the stirring time of step 3 is 60-90 minutes.

Abstract

The invention relates to a waterborne industrial rustproof color paste and a preparation method thereof, wherein the rustproof color paste comprises the following raw material components in parts by mass: 45-65% of pigment, 4-7% of wetting dispersant, 5-10% of humectant, 0.05-0.1% of stabilizer, 0.01-0.5% of defoaming agent, 1-2% of acidic complexing agent, 0.05-0.3% of bactericide, 0.2-0.3% of PHregulator and 10-40% of deionized water. The rustproof color paste prepared by using the preparation method is not only suitable for rustproofness of a steel surface with a rusted and hard oxide scale layer or an old paint film, but also suitable for rustproofness of a stainless steel surface if being added into a waterborne industrial coating. In addition, the rustproof color paste prepared by using the preparation method is also environment-friendly when being used and further has good compatibility with various common waterborne industrial coatings such as an alkyd primer and an epoxy ester primer as well as water-soluble resin.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based industrial anti-rust color paste and a preparation method thereof. Background technique [0002] Steel structure engineering is a structure mainly made of steel, which is one of the main types of modern industrial and architectural structures, but its easy to corrode characteristics have brought huge losses to the national economy. [0003] In order to protect steel from rust, a layer of paint is often applied to its surface. In the past, before using paint, the base material must be thoroughly derusted, and even the original color of the metal base must be exposed; [0004] Large-scale steel installations and facilities, such as oil storage tanks, iron frames, iron bridges, sluice gates, ships, etc., can only be derusted by hand, which is not only labor-intensive and inefficient, but also difficult to remove rust; [0005] Small and medium-sized steel parts can ...
