Abstract

The invention relates to a road marking coating and a preparation method thereof. The road marking coating comprises the following components in parts by mass: 30-40 parts of modified epoxy resin, 50-60 parts of extender pigment, 10-15 parts of titanium dioxide, 20-30 parts of glass beads, 3-5 parts of a plasticizer, 5-10 parts of quartz sand, 2-3 parts of an ethylene-vinyl acetate copolymer, 1-3parts of polyethylene wax, 2-4 parts of an adhesion promoter and 1-2 parts of an ultraviolet light absorber. The road marking coating provided by the invention is good in wear resistance and high in compressive strength, and then the added glass beads can reflect light continuously, so that the indication effect at rain nights is good, safety of vehicles during running at rain nights can be improved, and probability of traffic accidents is reduced.

Description

technical field

[0001] The invention relates to the technical field of coatings, in particular to a road marking coating and a preparation method thereof. Background technique

[0002] Road marking paint is a paint that is painted on the road surface to indicate traffic. With the rapid development of my country's transportation industry, the demand for road marking paint is gradually increasing. Road marking paints are generally divided into four categories: solvent-based, hot-melt, two-component, and water-based. Solvent-based road marking paints mostly use chlorinated rubber, epoxy resin and acrylic resin as film-forming substances, which often require a large amount of organic solvents, and then the release of organic solvents will cause environmental pollution, so its market share is gradually decreasing. Hot-melt road marking paints generally use petroleum resins, natural resins, etc. as film-forming substances. Coating has the characteristics of short drying time, go...
