Abstract
The invention relates to anti-sticking water-based coating which comprises, by weight, 50-80 parts of polymer latex, 10-15 parts of methyl methacrylate, 6-9 parts of butyl acrylate, 2-5 parts of 2-ethylhexyl acrylate, 3-6 parts of dibutyl maleate, 0.6-1 part of hydroxyethyl acrylate, 0.3-1.0 part of sodium dodecyl sulfate, 0.1-0.4 part of potassium peroxydisulfate, 0.05-0.2 part of sodium acetate, 1-10 parts of water repellent agents and 0.5-5 parts of fluorine-modified surface additives with hydrophobic and oleophobic structures. The anti-sticking water-based coating is non-toxic and harmless, thereby being less in environmental pollution; a coating layer formed after coating is not only high in brightness and excellent in toughness and explosive spalling resistance but also good in ageing resistance and weather resistance, and is extraordinary in subsequent processing performance so that rapid and efficient gold stamping processing can be carried out, and gold stamping effects are fine; and the water-based coating is anti-sticking and is environment-friendly water-based coating beneficial to surface clearness maintaining after coating.
Description
technical field [0001] The invention relates to a water-based paint, in particular to an anti-sticking water-based paint. Background technique [0002] In the packaging and printing industry, after coating a layer of paint on the white cardboard, it can form a high-gloss paper with high brightness. As people's requirements for the decorative effect of packaging materials and the safety and hygiene during use are increasing, high-gloss paper is not only required to have high brightness, which is suitable for subsequent fast and efficient bronzing processing, but also requires that stains are not easy to adhere to and easy to remove during use. Moreover, as people pay more and more attention to environmental protection, it is also required that the coatings emit less or no harmful substances during use, which meets the requirements of environmental protection. [0003] Although the coating formed after oil-based coating can meet the requirements of high brightness and subsequ...
