Embodiment 1
[0026] Single-component fluorocarbon coatings, by weight parts, include the following components: 45 parts of water-based vinyl fluorocarbon emulsion, 5 parts of butyl acetate, 0.3 parts of non-ionic wetting agent, 0.7 parts of polyacrylamide, silicone 0.3 parts of defoamer, 0.7 parts of associative thickener, 11 parts of lithopone, 16 parts of organic pigment, 21 parts of water, 2.5 parts of nano-magnesium oxide, and 2.4 parts of nano-zinc hydroxide.
[0027] The steps of its preparation method are as follows:
[0028] (1) Add nano-magnesium oxide powder and nano-zinc hydroxide powder into a ball mill and mill for 3 hours, sieve and cool to room temperature naturally to obtain nano-mixed powder, add nano-mixed powder to ten times the weight of water, stir and disperse After 4 hours, the nano-mixture was obtained;
[0029] (2) Add titanate coupling agent to absolute ethanol, ultrasonically disperse at 70 Hz for 20 minutes to obtain a coupling agent solution, adjust the pH val...
