Road reflective marker line coating

Abstract

The invention discloses a road light-reflective mark coating which comprises components in the following mass percent: 15 percent to 25 percent of C5 petroleum resin, 1 percent to 2 percent of ethylene-acetic acid polyvinyl, 1 percent to 1.5 percent of Tissuemat E, 3 percent to 5 percent of titanium white powder, 8 percent to 12 percent of quartz sand, 1.5 percent to 2 percent of di-1-octyl, 8 percent to 12 percent of 1.5RI glass beads, 8 percent to 12 percent of 1.93RI glass beads, 0.1 percent to 0.3 percent of calcium stearate, 36 percent to 46 percent of calcite powder, 0.25 percent to 0.29 percent of bentonite and 0.02 percent to 0.04 percent of optical brightener. The coating of the invention is fine; the coating interface of the glass beads is quite smooth and close to an ideal concave mirror, can focus the light and has good reflection effect. The glass beads which are added in have high refraction rate and small refraction angle of the light; the refraction angle for the reflected light to be obliquely incident from water into the air is small, and the return reflection effect in rainy nights is good.

Description

【Technical field】 [0001] The invention relates to the field of municipal road engineering, in particular to a road reflective marking paint, in particular to a hot-melt spraying underwater reflective road marking paint. 【Background technique】 [0002] Markings have an important function in guiding traffic, and all countries attach great importance to its application. In order to ensure the visibility of the markings at night, the highway management departments require the markings to have retro-reflective properties. In fact, most markings today are retroreflective in normal weather conditions. However, these markings are bound to greatly weaken or even eliminate the retro-reflection phenomenon of the markings in the rainy night environment when the rainwater floods the reflective medium. In order to overcome the above problems, people have developed oscillating rainy night reflective marking lines and structural marking lines. [0003] A drainage layer can be formed betw...

AI Technical Summary

Problems solved by technology

[0005] 1. After the marking line is submerged by the accumulated water on the road at night, when the headlights of the car shine on the marking line with water film on the surface, the driver cannot see the marking line clearly;

[0006] 2. In order to obtain the retro-reflection phenomenon, the marking line must be made very thick, and the amount of raw materials used is greatly increased, resulting in greater waste;

[0007] 3. Because the moment of moment of the glass beads with large particle size is usually larger when the force is applied, the glass beads with large particles are more likely to fall off the marking surface during the use of the marking line;

The refraction angle of glass beads with a refractive index of 1.50RI is relatively large. The light from car lights is refracted by the rainwater layer to the surface of glass beads and then refracted three times and reflected once.

[0009] Therefore, the retro-reflection effect of the current reflective marking lines in the rainy night environment is poor, the amount of raw materials used is large, and the waste is serious
