Abstract

The invention discloses a high-adhesion road marking paint and a preparation method thereof. The invention is characterized in that the high-adhesion road marking paint is prepared from the following raw materials in parts by weight: 1-3 parts of aluminum oxide, 1-3 parts of GdCl3, 6-10 parts of ethanediol, 1-2 parts of zirconium oxide, 1-3 parts of NaF, 40-50 parts of water-based polyurethane emulsion, 3-5 parts of ethyl acrylate, 1-2 parts of corundum, 1-3 parts of citric acid, 10-15 parts of titanium white, 10-15 parts of barite powder, 10-15 parts of glass microballoon, a right amount of deionized water and a right amount of ethanol. The water-based polyurethane paint disclosed by the invention has the characteristics of resource saving, lower pollution, low toxicity and environment friendliness. The rare-earth nano luminescent material is utilized to improve the luminescence of the water-based polyurethane paint, so that the water-based polyurethane paint is more suitable for use on roads with poor illuminating effect, thereby lowering the road potential safety hazard. The aluminum oxide and corundum are matched and added to enhance the adhesion strength and mechanical strength of the paint.

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 with good adhesion 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 body. Small, ...
