Weather-proof reflecting coating material used for road labels, and preparation method thereof

Abstract

The invention discloses a weather-proof reflecting coating material used for road labels. The weather-proof reflecting coating material used for road labels comprises, by weight, 7 to 9 parts of an energy-storage self luminescent material, 4 to 6 parts of a nanometer grade reflecting powder, 5 to 7 parts of a reflecting material, 20 to 30 parts of a highlight transparent polyurethane emulsion, 10 to 14 parts of water-borne alkyd resin, 2 to 4 parts of an aluminate coupling agent, 8 to 10 parts of a processing auxiliary agent, 4 to 6 parts of an ore additive powder material, 5 to 7 parts of anti-cracking fiber, and 3 to 7 parts of polyethylene wax. The weather-proof reflecting coating material possesses excellent energy storage self luminescent and reflective functions, so that road labels are provided with excellent reflective identification properties at dark and light conditions, light intensity is high, and fluorescent lifetime; the adhesive force is relatively high; high temperature resistance is excellent; corrosion and moisture resistance is achieved; the material cost of the preparation method is relatively low; the raw materials are easily available; the preparation method is simple; and high practical value and promising application prospect are achieved.

Description

technical field [0001] The invention relates to the technical field of road signs, in particular to a weather-resistant reflective coating material for road signs and a preparation method thereof. Background technique [0002] At present, the common road sign paint widely used in the market is passive reflective, which plays a very important role in regulating driving and maintaining traffic safety. However, there are still some defects in ordinary signage coatings: First, even if the ordinary hot-melt road signage is illuminated by light in a foggy environment, the light will be scattered by water droplets and dust in the air, thereby reducing the recognizability of the signage 2. On road sections without lights at night, such as remote mountainous roads and township roads, non-motor vehicles and motor vehicles without lights (lights are broken), pedestrians will bring great traffic problems because they cannot see the signs. Potential safety hazard; the third is that in t...

However, there are still some defects in ordinary signage coatings: First, even if the ordinary hot-melt road signage is illuminated by light in a foggy environment, the light will be scattered by water droplets and dust in the air, thereby reducing the recognizability of the signage 2. On road sections without lights at night, such as remote mountainous roads and township roads, non-motor vehicles and motor vehicles without lights (lights are broken), pedestrians will bring great traffic problems because they cannot see the signs. Potential safety hazard; the third is that in the rainy night, due to the existence of water droplets in the air and the water layer on the ground, most of the light that irradiates on the water layer on the road surface will be scattered and refracted out of people's sight, so that people cannot see it. Signage; Fourth, under the harsh conditions of rain and poor light during the day, and when the ambient brightness is low, the legibility of the signage is also very poor
