Protuberant hot-melt road marking coating, and preparation method and construction method thereof

Abstract

The invention discloses a protuberant hot-melt road marking coating, and a preparation method and a construction method thereof, and relates to the technical field of road marking construction. The protuberant hot-melt road marking coating is mainly prepared from the following raw materials by the weight percentage: 3-8% of petroleum resin, 3-8% of rosin resin, 2-6% of polyamide resin, 0.5-1.5% ofalkyd resin, 20-50% of a reflective material, 1-10% of a pigment, 0-1.5% of an anti-sedimentation agent, and the balance a filler. The defects of poor formability, poor cohesion, poor low temperatureresistance, easy cracking when being used in winter and poor deformation resistance at high temperature of a traditional road marking coating are alleviated. The formula of the protuberant hot-melt road marking coating improves the performance of the coating through the cooperative use of petroleum resin, rosin resin, polyamide resin and alkyd resin; pigments and fillers, the reflective materialand the optional anti-sedimentation agent are added for compounding, so the product has the advantages of good performance, improved high temperature anti-compressive performance, no cracking in winter and no collapse when being pressed in summer.

Description

technical field [0001] The invention relates to the technical field of road marking construction, in particular to a protruding hot-melt road marking paint and a preparation method and a construction method thereof. Background technique [0002] Road markings are one of the important safety facilities of road traffic. They are used to regulate the passage of vehicles and pedestrians, so that they can go their own way without interfering with each other, so as to ensure safe and smooth traffic. It is called "lifeline". Road marking paint is used for marking roads, urban roads, airports, ports, factories, mines, residential areas, parking lots and other traffic markings. Hot-melt marking paint is widely used in high schools, highways and urban roads because of its durability and night vision. Hot-melt marking paint is a solid powder block at room temperature, and it will melt into a flowing liquid when heated to 180-220°C, and it will become a solid marking after it is scrape...

AI Technical Summary

Problems solved by technology

[0004] (1) The formability of the paint is poor, so that the paint of one formula is only suitable for the construction of marking lines with one protruding shape, and the construction of other protruding shapes is easy to cause collapse, and the applicability is small;

[0005] (2) Poor adhesion between paint and highly reflective materials and roads;

[0006] (3) Poor low temperature resistance, easy to crack in winter;

[0007] (4) The high temperature resistance is poor, it is easy to collapse in summer, and the protruding part is easy to be crushed by the wheel;

[0008] (5) The marking line is easy to block the rainwater, resulting in water accumulation on the road
