Abstract

The invention provides a wear-resistant high-brightness reflective hot-melt marking coating, which belongs to the field of road marking construction. A marked line is divided into a surface layer anda bottom layer and further comprises glass beads, the glass beads are located between the surface layer and the bottom layer, and the structure of the marked line is shown in the specification, namelya is the surface layer, b is the glass beads and c is the bottom layer. Specifically, the surface layer is prepared from hydroxymethyl cellulose, nitrocellulose, acrylic resin, ethyl cellosolve acetate and polyethylene wax through hot melting, and has high transparency and high wear resistance; and the bottom layer is prepared by melting titanium dioxide, petroleum resin, a plasticizer, EVA, PLA-PEG and flaky aluminum oxide, has high reflectivity and has high adhesion to glass beads. The hot-melt marking coating provided by the invention is durable and high in light reflection, and the actualperformance is higher than the existing standard requirements.

Description

technical field [0001] The invention relates to the field of road marking construction, in particular to a high-brightness and durable Class III reflective hot-melt marking paint, a preparation method thereof and a marking construction process. Background technique [0002] As the most basic, effective and cost-effective traffic management facility, road markings play an extremely important role in highway management. Domestic road marking materials are mainly hot-melt marking materials. Hot-melt coatings for road signs can be applied quickly and can be used in about half an hour after coating construction. They have thick coatings, friction resistance, durability, and do not contain organic solvents. , Environmental friendliness and so on. Hot-melt coatings for road signs are currently the most widely used coatings on highways and urban traffic roads. [0003] Domestic main requirements for hot-melt marking paint: shelf life of more than one year; good wear resistance; hi...
