Abstract

The invention provides a high-brightness reflective hot melt coating material and a preparation method thereof. The high-brightness reflective hot melt coating material is prepared from the followingmain components in parts by weight: 10 to 15 parts of an EVA (Ethylene Vinyl Acetate) hot melt adhesive, 3 to 5 parts of SEBS (Styrene Ethylene Butadiene Styrene Copolymer), 5 to 10 parts of a reflective material, 10 to 20 parts of titanium dioxide, 10 to 30 parts of filler, 1 to 3 parts of nano strontium aluminate fluorescent powder and 0.5 to 1 part of a rare-earth luminescent material. The high-brightness reflective hot melt coating material provided by the invention is capable of remarkably increasing the wear resistance, the thermal stability and the cracking resistance on the premise that other properties of the high-brightness reflective hot melt coating material are not reduced; the nano strontium aluminate fluorescent powder and the rare-earth polymer luminescent material are cooperatively used in the high-brightness reflective hot melt coating material, the rare-earth polymer luminescent material is capable of absorbing and accumulating light rays exposed by headlights and converting the light rays into visible light under the environment of poor light rays at night or in rainy days, and the rare-earth polymer luminescent material is in combined action with the fluorescent powder and glass beads, so that the luminescent intensity is ensured, and the visibility is enhanced.

Description

technical field [0001] The invention belongs to the technical field of chemical compositions, and in particular relates to a performance-improved hot-melt paint and a preparation method thereof, in particular to the application of the paint in road markings. Background technique [0002] In recent years, with the rapid development of highway construction, the application environment of road marking paint is relatively severe, not only to withstand the test of environmental temperature changes, sun and rain, but also to face the rolling and friction from wheels It is easy to fall off during use, resulting in a decrease in the reflective ability of road markings. On the other hand, the surface of the marking paint will absorb a large amount of pollutants during use, reducing the brightness and reflective effect of the marking paint; another problem is that the reflective effect becomes worse at night or in rainy days, or even completely loses the reflective performance. These...
