Embodiment

[0024] A luminescent reflective road marking paint with high coloring degree is characterized in that it is made of the following raw materials in parts by weight:

[0025] ZnO3, GdCl 3 3. Ethylene glycol 10, heavy calcium carbonate 2, NaF 3, water-based polyurethane emulsion 50, ethyl acrylate 5, citric acid 3, titanium dioxide 15, barite powder 15, glass microspheres 15, deionized water, ethanol Appropriate amount;

[0026] The content of the aqueous polyurethane emulsion is 40-50%.

[0027] The luminescent reflective road marking paint with high coloring degree and its preparation method is characterized in that it is made by the following steps:

[0028] a. GdCl 3 Dissolve in 3-5 parts of ethylene glycol solution, stir until clear solution;

[0029] b. Dissolve NaF in the remaining ethylene glycol solution, stir until the solution is clear, then quickly mix it with the clear solution obtained in step a, and stir evenly;

[0030] c. Add sodium lauryl sulfate to the li...

Abstract

The invention discloses a high-pigmentation-degree light-emitting and light-reflecting road marking coating and a preparation method thereof. The high-pigmentation-degree light-emitting and light-reflecting road marking coating material is characterized by being prepared from the following raw materials in parts by weight: 1-3 parts of zinc oxide, 1-3 parts of GdCl3, 6-10 parts of ethanediol, 1-2 parts of coarse whiting, 1-3 parts of NaF, 40-50 parts of aqueous polyurethane emulsion, 3-5 parts of ethyl acrylate, 1-3 parts of citric acid, 10-15 parts of titanium pigment, 10-15 parts of barite powder, 10-15 parts of glass micro-beads, a proper amount of deionized water and a proper amount of ethanol. The aqueous polyurethane coating disclosed by the invention has characteristics of being resource-saving, pollution-lowering, low-toxic and environment-friendly, meanwhile, the light-emitting performance of the aqueous polyurethane coating is improved by utilizing a rare-earth nano light-emitting material, the aqueous polyurethane coating is enabled to be more appropriately applied to a section, with a poor illuminating effect, of a road, and potential safety hazards of the road are decreased; by applying the zinc oxide and the barite powder, the coating is enabled to be high in stability, whiteness degree and pigmentation degree.

Description

technical field [0001] The invention relates to a road marking paint, which belongs to the field of paints, in particular to a luminescent reflective road marking paint with high coloring degree and a preparation method thereof. Background technique [0002] Road markings are used to guide traffic and are an important infrastructure to improve driving safety and ensure smooth road traffic. my country is gradually improving the level of transportation infrastructure and building a modern road network. At the same time, with the continuous increase of vehicles, the road load and marking wear are increasing. These all show that the current traffic marking paint has a huge market demand. [0003] Among them, water-based paint is a relatively new type of paint in the paint market. Compared with traditional solvent-based paints, water-based paints use water as a solvent, and the VOC in the process of production and use is far lower than that of solvent-based paints, which is harmf...
