Abstract

The invention provides hot melt coating for road markings. The hot melt coating is prepared from the following raw materials in parts by mass: 180 to 200 parts of calcium triple superphosphate powder,100 to 110 parts of quartz sand with the size of 40 to 80 meshes, 100 to 110 parts of quartz sand with the size of 120 to 160 meshes, 50 to 55 parts of C5 petroleum resin, 20 to 25 parts of glass beads, 10 parts of titanium white, 10 to 15 parts of a compound auxiliary agent and 5 to 6 parts of epoxidized soybean oil. According to the hot melt coating provided by invention, the production cost isreduced under the condition that each performance index of the hot melt coating is not reduced, and properties including compression strength, a softening point and the like of the coating are improved; the hot melt coating accords with a development trend of a coating industry in China.

Description

technical field [0001] The invention relates to a road marking paint, in particular to a hot-melt road marking paint. Background technique [0002] As a safety mark, road markings play a very important role in road traffic. There are three types of road marking paints currently used in my country: hot-melt type, water-based and room temperature solvent-based. Although due to the vigorous promotion of two-component road markings in recent years, room temperature solvent-based coatings have occupied an increasing market share, but hot-melt coatings are low in cost and are still the most widely used road marking coatings in my country. [0003] Although a small amount of organic additives are added to hot-melt coatings, compared with room-temperature solvent-based coatings containing a large amount of volatile organic solvents, hot-melt coatings have a higher solid content, less environmental pollution, and are more environmentally friendly. [0004] Although hot-melt coating...
