Although the proportion of ordinary arterial roads in mountainous areas in my country's road network is small, the proportion of traffic accidents is relatively large, and the accident severity is serious. Especially at night, drivers have poor physiological conditions, are prone to fatigue, and have reduced vision. Although the light of the vehicle also has an illumination effect, the driver's field of vision at night is still very narrow. In the sharp curve section, the judgment of the line shape is inaccurate, which may easily cause traffic accidents. Therefore, it is necessary to develop a self-illuminating modified marking adhesive suitable for roads in mountainous areas at night.

After the road marking construction is completed, epoxy resin, glass fiber powder, quartz sand, glass beads, dispersant, and adjacent Diisooctyl phthalate, toluene, energy storage luminescent materials and pigments are mixed, mechanically stirred in a stirrer at room temperature, and then added with curing agent and stirred to obtain line paint latex. When the viscosity reaches 11000-14000mPa.s at 25°C, The line paint latex is evenly sprayed on the road markings with a thickness of 0.5-1.0 mm, and cured at room temperature to obtain self-illuminating modified markings.

The present invention has the following beneficial effects:

Various raw materials of the two-component line marking paint of the present invention are commercially available general industrial raw materials, with low production cost, simple process, and good energy storage and self-luminous function.
