Problems solved by technology

Judging from similar products imported from abroad, only iron oxide blackening components are added to it, resulting in the illusion of rapid blackening after coating
Therefore, the corrosion resistance is poor or poor

Embodiment 1

[0022] The water-based silicone resin and the water-based acrylic resin are reacted to prepare a silicon-containing acrylic resin emulsion, which is cooled for later use. According to the mass percentage, take 20% of silicon-containing acrylic resin emulsion, 20% of anti-rust and anti-rust agent Kx123, anti-rust and flame retardant Al 2 o 3 ·3H 2 O 5%, Zn(H 2 PO 4 ) 2 2H 2 O 5%, pigment and filler 4%, H 2 O 46%, the above materials are added one by one, fully stirred and reacted, and it can be used as an environmentally friendly water-based rust-removing and anti-rust paint for general primers.

Embodiment 2

[0024] The water-based silicone resin and the water-based acrylic resin are reacted to prepare a silicon-containing acrylic resin emulsion, which is cooled for later use. According to mass percentage, take silicon-containing acrylic acid emulsion 48%, Kx123 20%, Al 2 o 3 ·3H 2 O 5%, Al(H 2 PO 4 ) 3 2H 2 O 5%, pigment and filler 4%, H 2 O 18%, add the above-mentioned materials one by one, fully stir and react, and it can be used as an environmentally friendly water-based rust-removing and anti-rust paint for advanced primers.

Embodiment 3

[0026] The water-based silicone resin and the water-based acrylic resin are reacted to prepare a silicon-containing acrylic resin emulsion, which is cooled for later use. According to the mass percentage, take silicon-containing acrylic emulsion 52%, Kx123 5%, Al 2 o 3 ·3H 2 O 7%, ZnAl(H 2 PO 4 )n·xH 2 O 8%, pigment and filler 4%, H 2 O 24%, add the above-mentioned materials one by one, fully stir and react, and it can be used as an environmentally friendly water-based rust-removing and anti-rust paint for matching topcoats.

Abstract

The invention relates to an environmental-friendly aqueous dust-removing and dust-preventing paint for a steel structure. The paint is mainly prepared from the following components in percentage by mass: 15-60% of a silicone-contained acrylic resin solution, 1-40% of a rust-converting and rust-preventing agent, 5-30% of a rust-preventing flame retardant, 3-10% of pigments and filler and the balance of water. According to the dust-removing and dust-preventing paint provided by the invention, only loose rust scales on the surface and crusty old paints and oil strains need to be removed without complete polishing; the paint does not need to be diluted or is diluted with a small amount of water and can be used directly after being opened; the paint is commonly smeared once or twice, the surface dry time is 30-60 minutes, and the paint is convenient to construct. The paint is aqueous and environmental-friendly, non-toxic, harmless and odorless, free of damages to the environment and a human body, incombustible and inexplosive and convenient to convey; the paint is good in compatibility with other marketed intermediate paints and finishing paints. The dust-removing and dust-preventing paint provided by the invention is small in specific gravity and great in coating rate, and 8-12 square meters can be coated by using one kilogram of the paint; the use of the paint has the advantages of high efficiency and small labor intensity; the construction period can be shortened by 40%, and the unit manual cost can be lowered by 60%. The tools used are washed by water and therefore the consumption is less.

Description

technical field [0001] The invention relates to an environment-friendly water-based rust-removing and anti-rust paint for steel structures, which belongs to the technical field of water-based anti-rust paint. Background technique [0002] Antirust paint or antirust paint for steel components is a solvent-based paint, also known as paint. It is highly toxic, has a smoky smell and pollutes the environment. In the past ten years, a kind of water-based paint or water-based paint has emerged at the historic moment, and there are patents on the market one after another. There are both at home and abroad, especially in recent years, the good and the bad are mixed, and the rapid development has the potential to replace paint. Such as the water-based anti-rust paint with rust in my country's patent 01126779, the nano-water-based anti-rust paint in 200410016326 and a kind of water-based anti-rust paint with rust in 201110138765; there are also international ones that have entered t...
