Abstract

The invention relates to hot melting reflective type road reticule coating and belongs to the technical field of road reticule coating. The hot melting reflective type road reticule coating is prepared by mixing the following components in parts by mass: 110 to 120 parts of fillers, 20 to 25 parts of modified rosin-alkyd resin, 5 to 10 parts of EVA resin, 7 to 8 parts of pigment, 2.0 to 2.4 partsof a plasticizer and 40 to 50 parts of glass microbead. The hot melting reflective type road reticule coating provided by the invention is simple and convenient to construct, only needs to be paved with one layer, and has a remarkable anti-cracking property, wear resistance, corrosion resistance, anti-fouling property and insusceptibility to fall off.

Description

technical field [0001] The invention relates to the technical field of road marking paint, more specifically, it relates to a hot-melt reflective road marking paint. Background technique [0002] Reflective road markings are important to assist vehicles in driving. At night, the centerline prevents collisions when approaching vehicles, the lane dividers guide vehicles to travel efficiently within the lane, and during the day, vehicles travel more safely and quickly. [0003] According to the type of paint used, road markings are divided into: normal temperature solvent type, heating solvent type, and hot melt type marking. Hot-melt road marking paint was first successfully developed in Europe in the mid-1950s, and my country began to use it after the 1990s. The biggest feature of reflective hot-melt marking is that the thickness of the coating is about 1.5-2.5mm, which is 10 times that of solvent-based marking at room temperature, and has good wear resistance; the hot-melt...
