Problems solved by technology

Among them, the most widely used hot-melt marking paint has many defects, such as high construction temperature, high energy consumption, poor safety, poor adhesion between resin and reflective glass beads, so that the reflective effect is not durable, etc.
Solvent-based marking paint contains a large amount of volatile organic compounds, which will cause pollution hazards to people and the environment during the construction process, and the construction film thickness is low, the reflection effect is not good, and the wear resistance and durability are poor

Abstract

The invention discloses a water-based self-luminous reflective marking coating for rain night. The water-based self-luminous reflective marking coating comprises a component A and a component B. The component A is a coating matrix, and the component B comprises high-reflection reflective beads used for being spread on the surface of the coating matrix. The coating matrix comprises the following components in parts by mass: 25-50 parts of water-based film-forming resin, 25-50 parts of pigment and filler, 5-20 parts of glass beads, 1-10 parts of an auxiliary agent and 1-10 parts of water. The marking paint is safe and environment-friendly, and has good wear resistance, weather resistance, rainwater resistance, acid and alkali resistance and good reflective property and luminous effect. The invention also discloses a preparation method of the marking paint, a road marking and a construction method of the road marking.

Description

technical field [0001] The invention relates to the technical field of road marking paint. More specifically, it relates to a water-based self-luminous reflective rainy night marking paint and its preparation method, road marking and its construction method. Background technique [0002] With the rapid development of national transportation and the blessing of artificial intelligence and 5G communication technology, a transportation network that meets the needs of smart cities and autonomous vehicles is particularly important. As one of the important road infrastructure, road markings need to have better stability, durability, and easy identification to ensure that autonomous vehicles can drive safely and efficiently. In addition, there are many market demands for improving the environmental protection, construction safety, and flexible use of marking materials. At present, the materials used for road marking in China are mainly marking paint, and some areas abroad will us...
