Description
Technical Field
The invention belongs to the technical field of chemical compositions, particularly relates to a hot-melt coating with improved performance and a preparation method thereof, and particularly relates to application of the coating in pavement marking.
Background
In recent years, with the rapid development of highway construction, the application environment of the road marking paint is severe, and the road marking paint is not only subject to the tests of environmental temperature change, sun and rain, but also subject to rolling and friction from wheels and the like, and is easy to fall off in use, so that the light reflecting capacity of the road marking is reduced. On the other hand, the surface of the marking paint can adsorb a large amount of pollutants in the using process, so that the brightness and the light reflecting effect of the marking paint are reduced; there is also a problem that the light reflecting effect at night or in rainy days becomes poor and even the light reflecting performance is completely lost. These factors all present a danger to the driving safety of the road.
At present, the improvement method of the night luminescence and the rainy day luminescence of the marking paint is usually realized by improving the glass beads, but the conventional reflective materials such as the glass beads and the like are usually granular and exist in the marking paint, and the reflective materials fall off along with the abrasion of the friction of vehicle tires, road cleaning operation and the like in the using process, so that the reflective effect and the service life of the marking are obviously reduced, and in addition, the improvement process of the glass beads is quite complicated.
CN107573777A discloses a hot-melt type marking paint, wherein it is disclosed that nanometer strontium aluminate phosphor and rare earth high molecular photoluminescence material are added into the hot-melt type paint to improve the visibility of the marking paint. However, the components of the coating are complex, especially the multilayer arrangement comprising a bottom layer, a surface layer and an intermediate layer, the construction period is long, the construction process is complex, and the cost is high. In addition, this patent does not disclose a specific kind of rare earth polymer photoluminescent material.

The construction method of the coating comprises the following steps: heating to 180-220 ℃ by a hot melting kettle, stirring while keeping the temperature for 3-5 minutes to form a flowing state, coating the flowing state on a road surface by a special construction machine, and cooling to form a firm coating.
Compared with the prior similar products, the coating has the following characteristics:
(1) the EVA hot melt adhesive with specific composition and performance is creatively selected to be matched with SEBS (hydrogenated butadiene-styrene resin) with specific content, so that the wear resistance, the thermal stability and the crack resistance are obviously improved on the premise of keeping other performances of the coating not to be reduced;
(2) the nano strontium aluminate fluorescent powder and the rare earth polymer luminescent material are matched in the coating, so that at night or in an environment with poor light in rainy days, the rare earth polymer luminescent material can absorb and accumulate light irradiated by car lamps and the like, convert the light into visible light, and jointly act with the fluorescent powder and glass beads, so that the luminous intensity is ensured, and the visibility is enhanced.
(3) In the preferred scheme, the high molecular micro/nano luminescent composite fiber obtained by spinning the high molecular doped silicon dioxide embedded organic rare earth complex is selected, so that the luminescent property is improved, the addition of the substance also has the effects of an interface agent and a reinforcing agent, and the method is hardly thought by the technical personnel in the field of mass existing chemical raw materials.
(4) The marking line coating can be formed by one-time coating, and can be used for traffic in 3 minutes.
