Embodiment

[0024] A limestone-containing luminescent reflective road marking paint is characterized in that it is made of the following raw materials in parts by weight:

[0025] Limestone 2, GdCl 3 3. Ethylene glycol 10, boron oxide 2, NaF 3, water-based polyurethane emulsion 50, ethyl acrylate 5, glycerin 2, citric acid 3, titanium dioxide 15, barite powder 15, glass microspheres 15, acrylic resin emulsion, Appropriate amount of deionized water, appropriate amount of ethanol;

[0026] The content of the water-based polyurethane emulsion is 40-50%, and the solid content of the acrylic resin emulsion is 20-40%.

[0027] The luminescent reflective road marking paint containing limestone and its preparation method are 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 to a clear solution, then quickly mix with t...

Abstract

The invention discloses a limestone-containing light-emission and reflection road marking coating and a preparation method thereof. The limestone-containing light-emission and reflection road marking coating is prepared from the following raw materials in parts by weight: 1-2 parts of limestone, 1-3 parts of GdCl3, 6-10 parts of ethylene glycol, 1-2 parts of boric oxide, 1-3 parts of NaF, 40-50 parts of aqueous polyurethane emulsion, 3-5 parts of ethyl acrylate, 1-2 parts of glycerinum, 1-3 parts of citric acid, 10-15 parts of titanium dioxide, 10-15 parts of blanc fixe, 10-15 parts of glass beads, a proper amount of acrylic resin emulsion, a proper amount of deionized water and a proper amount of ethanol. The limestone-containing light-emission and reflection road marking coating disclosed by the invention has the characteristics of resource conservation, pollution reduction, low toxicity and environment protection, and meanwhile as a rare-earth nano light-emitting material is adopted to improve the light emission property of the aqueous polyurethane coating, the aqueous polyurethane coating is particularly applicable to roads under poor lighting conditions, and thus the potential safety hazard of the roads can be reduced.

Description

technical field [0001] The invention relates to a road marking paint, which belongs to the field of paints, in particular to a limestone-containing luminescent reflective road marking paint 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 harmful to...
