Abstract

The invention provides a wear-resistant high-brightness reflective hot-melt marking paint, which belongs to the field of road marking construction. The marking line is divided into surface layer and bottom layer, and also contains glass beads. The glass beads are located between the surface layer and the bottom layer. The schematic diagram of the marking line structure is as follows, where a is the surface layer, b is glass beads, and c is the bottom layer. Specifically, the surface layer is made of hydroxymethyl cellulose, nitrocellulose, acrylic resin, ethyl cellosolve acetate and polyethylene wax, which has high transparency and high wear resistance; the bottom layer is made of titanium dioxide, Fusion made of petroleum resin, plasticizer, EVA, PLA‑PEG and aluminum oxide flakes, it is highly reflective and has high adhesion to glass beads. The hot-melt marking paint provided by the invention has long-lasting and high reflection, and its actual performance is higher than the requirements of existing standards.

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...
