Abstract

The invention discloses flame-retardant waterborne polyurethane light-emitting reflective road marking paint and a preparation method thereof. The reflective road marking paint is characterized by being prepared from the following raw materials in parts by weight: 1-3 parts of 2, 4, 6-tribromophenyl acrylate, 1-3 parts of GdCl3, 6-10 parts of ethylene glycol, 3-5 parts of acetic ether, 1-3 parts of NaF, 40-50 parts of waterborne polyurethane emulsion, 3-5 parts of ethyl acrylate, 1-3 parts of citric acid, 10-15 parts of titanium dioxide, 10-15 parts of barite powder, 10-15 parts of glass beads, right amount of deionized water and right amount of ethanol, wherein the content of the waterborne polyurethane emulsion is 40-50%. The waterborne polyurethane paint disclosed by the invention has the characteristics of being resource-saving, low in pollution, low in toxicity and environmental-friendly; furthermore, a nano rare earth luminescent material is used for improving the luminescence property of the waterborne polyurethane paint, so that the waterborne polyurethane paint is more suitable for being applied to road sections with poor lighting effect, and the road potential safety hazard is reduced; the fire retardant element Br is introduced into styrene-acrylic resin, so that the defect of short time limit of an additive type flame-retarded paint is overcome, and the reflective road marking paint has good flame retardant property.

Description

technical field [0001] The invention relates to a road marking paint, which belongs to the field of paints, in particular to a flame-retardant water-based polyurethane light-emitting 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 pain...
