Problems solved by technology

[0004] However, with the continuous increase of road traffic pressure, the maintenance period of the road is shortened, and the traditional hot-melt marking paint can no longer meet the current use requirements. For the rapid road marking construction, the conventional performance of the marking paint, especially It is aimed at the retroreflection durability of the marking line, which puts forward higher requirements
[0005] The traditional hot-melt road markings mainly have the following problems: 1) Poor wear resistance. Half a year after the road is opened to traffic, the markings will be greatly worn, and the glass beads will fall off, resulting in a decrease in the retroreflective performance of the markings and

Abstract

The invention discloses a continuous reflective high-standard hot melt coating, which is prepared by mixing 13-20 parts of a resin film-forming substance, 30-35 parts of mixed glass beads, 10-20 parts of a filler and 3-6 parts of a functional aid, and the resin film-forming substance is prepared by mixing C5 petroleum resin, C9 hydrogenated petroleum resin and maleic anhydride modified rosin resin; and the mixed glass beads are formed by mixing glass beads with three particle size grades of 16-30 meshes, 30-50 meshes and 50-80 meshes. The continuous retroreflection value and the conventional performance of the coating are superior to those of a traditional hot melt coating, the later retroreflection performance can last for more than one year, and the road marking maintenance cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to a road marking paint, in particular to a hot-melt road marking paint. Background technique [0002] As the lifeline of controlling and guiding road traffic, road traffic markings are drawn on the road surface or other facilities with prescribed lines, arrows, characters, facade marks, raised road signs or other guiding devices to control and guide traffic and disperse traffic streaming facilities. [0003] With the rapid development of road construction in my country, the types of road marking paints have become more abundant, and the performance requirements have gradually increased. At present, marking paints are mainly divided into two categories: hot-melt and solvent-based, among which hot-melt marking paints are still the mainstream products in the market due to their low price and no volatile organic compounds. [0004] However, with the continuous increase of road traffic...
