The invention provides a water-based alkyd topcoat and a preparation method thereof. The water-based alkyd topcoat contains the following raw materials in parts by weight: 20-60 parts of water-based alkyd resin, 10-20 parts of rutile type titanium dioxide, 10-20 parts of barium sulfate, 0.1-2 parts of defoaming agent, 0.1-2 parts of flash rust-proofing agent, 2-15 parts of auxiliaries, 0.1-1 part of anti-settling agent, and 2-25 parts of water, wherein the auxiliaries include a dispersant, a thickener and a substrate wetting dispersant. The water-based alkyd topcoat achieves the national requirement on environment-friendly paint, is high in quality, has excellent corrosion resistance and weather resistance, and is stable in chemical properties and thermal storage performance.
Description
technical field [0001] The invention belongs to the field of chemical production and manufacture, and in particular relates to a water-based alkyd topcoat and a preparation method thereof. Background technique [0002] Water-based alkyd paint is mainly diluted with water, which has the characteristics of fast drying and good protection performance. It can be used as a protective paint for metal substrates. The paint can be used alone as a primer-in-one paint, or it can be used in conjunction with a water-based topcoat or a solvent-based topcoat. Suitable for protective finishing of metal substrates in industrial facilities, equipment and residential products. It can be applied by flood coating, dip coating, conventional air spraying, high pressure airless spraying and other methods. [0003] The product has the following advantages: water is used as the main solvent, and the content of volatile organic compounds is low. It is not easy to burn and is conducive to safe prod...
