Problems solved by technology

[0004] At present, some anti-corrosion coatings in the prior art are based on water-soluble resins. Although they have protective properties, they have the defects of strong odor and high VOC value, or they are only for the protection of brand-new materials, and they are not effective for rusted parts. Insufficient material protection
In addition, the water-based protective coatings in the prior art use a large number of raw materials containing heavy metals, which are harmful to the human body and the environment.

Abstract

The invention relates to the technical field of paint, in particular to water-based single-component air-dry paint used for machines and a production method of the water-based single-component air-dry paint used for the machines. The water-based single-component air-dry paint used for the machines is produced from water-based acrylic resin, a pH regulator, a defoaming agent, a wetting agent, titanium dioxide, anti-rust pigment, talcum powder, barium sulfate, calcium carbonate, a coalescing agent, a thickener, an anti-flash-rust assistant and water, wherein the anti-rust pigment is one or a composition of any two or more of zinc phosphate, aluminum tripolyphosphate, zinc aluminum phosphate, zinc molybdate and zinc borate. The selected anti-rust pigment not only can conduct charge migration on metal surfaces to prevent the metal surfaces from rusting, but also can conduct passivation and isolation on rusty metal surfaces to prevent the rusty metal surfaces from continuous oxidation and rusting. Moreover, due to the fact that no raw materials which contain heavy metal are used in a formula of the water-based single-component air-dry paint used for the machines, the water-based single-component air-dry paint used for the machines has the characters that the water-based single-component air-dry paint used for the machines is safe and environmentally friendly, and a VOC value is low. The production method has the characters that the process is simple, the production cost is low, and the production method can be suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based one-component self-drying paint for machinery and a preparation method thereof. Background technique [0002] Due to its environmental protection, low cost, and easy construction, water-based coatings have gradually become the development trend of future coatings. [0003] In recent years, direct or indirect economic losses caused by metal corrosion have exceeded hundreds of billions of dollars each year. Therefore, a low-cost environmentally friendly water-based coating is needed to protect it. [0004] At present, some anti-corrosion coatings in the prior art are based on water-soluble resins. Although they have protective properties, they have the defects of strong odor and high VOC value, or they are only for the protection of brand-new materials, and they are not effective for rusted parts. Insufficient material protection. In addition, the water-based prote...
