Problems solved by technology

[0002] Most of the anti-rust paints currently used in steel structures are solvent-based anti-corrosion paints, which contain a large amount of organic solvents, which will be released during production and construction, which will cause harm to the health of workers and pollute the environment.
Since the 1970s, the development of environmentally friendly anti-corrosion paints such as high solid content, solvent-free, powder and water-based paints has been carried out in foreign countries. Among them, water-based paints have low cost, safe and convenient construction, and easy control of film thickness. However, due to the high technical difficulty, great progress has been made at the end of a long period of time

Embodiment Construction

[0013] Table 1 is an example of the present invention, wherein the content of each component is in mass percentage, but the present invention is not limited to the following examples.

[0014] Table 1

[0015]

[0016] The paint preparation process is:

[0017] Component A:

[0018] ① Add water-based epoxy emulsion 3520-WY-55 to the slurry mixing container accurately, add additive 1 and additive 2 respectively (auxiliary 1 is the softened aqueous solution of wetting and dispersing agent byk190, and additive 2 is defoamer byk019 , defoamer byk034 and lauryl alcohol mixture), then add the remaining benzyl alcohol, demineralized water, and stir at low speed for 5 to 10 minutes.

[0019] ② Add filler and stir at low speed for 5-10 minutes.

[0020] ③Use a sand mill, ball mill or three-roll mill to grind to a fineness of less than 50 μm.

[0021] ④ Add water-based bentonite and water-based aluminum silver paste, and stir for 30 minutes.

[0022] ⑤ Filter with 100-mesh coppe...

Abstract

The invention relates to a middle coating of the high-performance rustproof paint such as epoxy zinc-rich primer, in particular to a water-based epoxy micaceous iron oxide rustproof paint and a preparation method thereof. The rustproof paint comprises a component A and a component B, wherein the component A comprises 25-50wt% of water-based epoxy emulsion, 1.2-2.0wt% of auxiliary agent, 1.5-5wt% of cosolvent, 40-60wt% of packing and 7-16wt% of softened water; and the component B comprises 85-95wt% of water-based epoxy curing agent and 5-15wt% of softened water; and the weight ratio of the component A to the component B is 100:10. The rustproof paint of the invention can overcome the shortages of the existing rustproof paint.
