Embodiment

[0006] Step 1: Add 28 parts of acrylic emulsion into the chemical reaction kettle, start the agitator at a speed of 40 rpm, slowly add 14 parts of iron oxide red and 6 parts of metal aluminum powder at room temperature, and react for 0.5 hours.

[0007] Step 2: Raise the temperature to about 35°C, add 5.5 parts of red lead, 0.5 parts of zinc chrome yellow, 2 parts of aluminum tripolyphosphate, and 0.5 parts of sodium hexametaphosphate in sequence, and stir and keep warm for 1 hour.

[0008] The third step: sequentially add 4 parts of sodium sulfate, 13 parts of talcum powder, 3 parts of 731 dispersant, 2 parts of dodecyl alcohol ester, and 1.5 parts of paint additives, and stir and keep warm for 1 hour.

[0009] Step 4: Cool down to room temperature, add 20 parts of water, and stir evenly to obtain the finished product.

Abstract

The invention discloses a preparation method of an aqueous rust-resisting paint, which can be widely applied as a prime paint for preventing rust on any steel product in the fields of containers, pipelines, chemicals, machineries, architectures, engineering members, bridges, vehicles, ships, iron gates, steel window frames, steel sheds, and the like. The product provided by the invention does not contain benzene. The product can be applied on non-rusted surfaces, and also can be applied on rusted surfaces after simple cleaning, such that the cost of steel structure surface treatment before painting can be substantially reduced. The rust-resisting paint is not toxic, not polluting, and not inflammable. With usage safety and reliable quality, the paint is a novel environmental protecting antirust material. The paint is produced from the raw materials of: acrylic emulsion, iron oxide red, metal aluminum powder, red lead, zinc yellow, aluminum tripolyphosphate, sodium hexametaphosphate, sodium sulfate, saponite, 731 dispersant, dodecanol ester, paint aids, and water.

Description

Technical field: [0001] The product of the invention belongs to the field of chemical building materials. Specifically relates to a preparation method of water-based antirust paint. Background technique: [0002] The antirust paint currently used is roughly two types: oily and water-based. The oil-based antirust paint film prepared with iron oxide red as the main ingredient has many excellent properties, but its weakness is that it is toxic and the oil stains are difficult to remove. The advantages of water-based anti-rust paint are easy to use, low price, and no oil pollution. However, the old products are harmful to operators because they contain toxic substances such as nitrite, and their use is also subject to certain restrictions. But along with the progress of science and technology, can reduce its harmfulness by improving formula, select substitute for use, and product of the present invention is exactly a kind of nontoxic water-based antirust paint. Anti-rust pigm...
