Problems solved by technology

However, due to the fact that the road surface is often covered with dust, the vehicles are rolling back and forth, the size of the glass beads, the roundness rate, and other factors cause the reflection effect of the reflective line to be very poor.
In such an environment with no light at night, poor reflective performance, and weak visual effect, it brings great danger to safe travel.

Abstract

The invention discloses a formula and preparation method of a road marked line coating; the formula comprises 14%-18% by volume of Jinsen resin, 2.5%-4.0% by volume of rutile titanium dioxide, 2%-4% by volume of a rare earth aluminate noctilucent powder, 0.8%-1.2% by volume of PE wax, 0.8%-2.0% by volume of an ethylene-vinyl acetate copolymer (EVA), 0.8%-1.8% by volume of dioctyl phthalate, 30%-55% by volume of a heavy calcium carbonate powder, 15%-25% by volume of quartz sand, and 18%-25% by volume of glass beads. The road marked line coating is characterized in that the luminescent material in the coating adopts an energy-storage type self luminescent material and still can give out light under conditions of night, especially rain night, and darkness, a good guiding effect is achieved, people are safer when going out at night, and occurrence of safety hidden danger at night is greatly reduced.

Description

technical field [0001] The invention relates to the field of public transportation, in particular to a formula and a preparation method of a road marking paint. Background technique [0002] At present, the widely used hot-melt reflective marking lines are in the form of surface sprinkled glass beads and internally mixed glass beads. The reflective performance of the reflective marking lines is due to the addition of reflective glass beads to the paint. Reflective glass beads are colorless, transparent balls that have the functions of refracting, focusing and directional reflection of light. Glass beads mixed into the paint or sprinkled on the surface of the film can greatly improve the visibility of markings by reflecting car lights back to the driver's eyes. Glass beads in the paint reflect light from car lights back into the driver's eyes. However, due to the fact that the road surface is often covered with dust, the vehicle is rolling back and forth, the size of the gl...
