preparation example Construction

[0038] In the second aspect, the present invention also provides a preparation method of water-based marking paint, comprising the steps:

[0039] S10, mixing the water-based acrylic emulsion, the fluorocarbon emulsion, the water-based epoxy emulsion, the water-based dispersant, and the antifoaming agent at a low speed until the mixture is uniform to obtain a first mixed solution;

[0040] S20, after slowly adding titanium dioxide, heavy calcium carbonate and nano-silicon carbide to the first mixed solution, stir until uniform to obtain a second mixed solution;

[0041] S30, adding aqueous wax solution, thickener, organic bentonite, and aqueous drier to the second mixed solution;

[0042] S40, adding ethanol, deionized water and multifunctional additives into the third mixed solution, stirring evenly, and after filtering, the filtrate is allowed to stand to obtain a water-based marking paint;

[0043] Wherein, based on the total weight of the water-based marking paint, the co...

Abstract

The invention provides waterborne marking paint and a preparation method and construction method thereof. The waterborne marking paint is prepared from, by weight, 15-35wt% of waterborne acrylic emulsion, 5-10wt% of fluorocarbon emulsion, 5-10wt% of waterborne epoxy emulsion, 1-3wt% of coalescing agent, 1-3wt% of waterborne wax emulsion, 0.5-5wt% of organic bentonite, 0.1-0.5wt% of antifoaming agent, 0.1-0.5wt% of thickener, 10-20wt% of nano-silicon carbide, 15-40wt% of heavy calcium carbonate, 5-10wt% of titanium dioxide, 1-3wt% of ethanol, 0.1-0.5wt % of waterborne dispersing agent, 0.5-1.5wt% of waterborne drier, 0.2-0.5wt% of multifunctional auxiliary agent and the balance deionized water; the particle size of silicon carbide is 600-900 nm. The waterborne marking paint has excellent quick-drying performance, abrasion resistance, weather resistance and stain resistance.

Description

technical field [0001] The invention belongs to the technical field of road markings, and in particular relates to a water-based marking paint and a preparation method and construction method thereof. Background technique [0002] The main function of road traffic markings is to guide and control vehicles to drive safely on the road. The all-weather visibility and slip resistance of road markings are important indicators to measure the performance of road marking coatings. At present, there are several kinds of marking coatings in the world: solvent-based marking coatings, hot-melt marking coatings, two-component marking coatings, and water-based marking coatings. Since the water-based marking paint uses water as a solvent, it can achieve clean production, is environmentally friendly, and has the advantages of good reflective effect and good repaintability. More than 80% of the water-based road markings in the United States are water-based road markings in Sweden and Finland...
