Abstract

The invention discloses a road marking coating containing nano-calcium carbonate and a preparation method thereof. The road marking coating is characterized by being prepared from the following raw materials by weight part: 3-5 parts of nano calcium carbonate, 1-3 parts of GdCl, 6-10 parts of glycol, 1-2 parts of hydroxyethyl cellulose, 1-3 parts of NaF, 40-50 parts of waterborne polyurethane emulsion, 3-5 parts of ethyl acrylate, 1-3 parts of iron powder, 1-3 parts of 1-2 citric acid, 10-15 parts of titanium dioxide, 10-15 parts of blanc fixe, 10-15 parts of glass beads and a defined amount of deionized water and ethyl alcohol. The aqueous polyurethane coating disclosed by the invention has the characteristics of resource saving effect, pollution reduction, low toxicity and environmental protection; a rare earth nanometer luminescent material is utilized to improve the luminescence property of the aqueous polyurethane coating; the coating is more fit for application to the road segment with poor illuminating effect; the potential safety hazard of road is reduced; the nano calcium carbonate is added, so that the water resistance, stain resistance, abrasion resistance and weather fastness of the coating are increased.

Description

technical field [0001] The invention relates to a road marking paint, which belongs to the field of paints, in particular to a road marking paint containing nano-calcium carbonate 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 the human...
