Embodiment 2

[0029] Weigh 20kg polybutylene modified C5 petroleum resin, 2kg EVA hot melt adhesive, 2kg PE wax, 7kg titanium dioxide, 30kg calcium carbonate, 18kg glass beads, 1kg plasticizer, 15kg quartz sand, 5kg ZTA~VE high elastic The anti-cracking particles were uniformly mixed according to the method in Example 1 to obtain an anti-cracking durable hot-melt road marking paint.

[0030] Test coating performance: 4h at ~25°C, 4h at 45°C as a cycle, no cracks after three consecutive cycles, the compressive strength of the coating at room temperature is 45MPa, the abrasion resistance index is 23mg, and the pull-out bonding strength is 6.7MPa.

Embodiment 3

[0032] Weigh 25kg polybutylene modified C5 petroleum resin, 1kg EVA hot melt adhesive, 3kg PE wax, 5kg titanium dioxide, 20kg calcium carbonate, 18kg glass beads, 3kg plasticizer, 20kg quartz sand, 5kg ZTA~VE high elastic The anti-cracking particles were uniformly mixed according to the method in Example 1 to obtain an anti-cracking and durable hot-melt road marking paint.

[0033] Test coating performance: 4h at ~25°C, 4h at 45°C as a cycle, no cracks after three consecutive cycles, the compressive strength of the coating at room temperature is 43MPa, the abrasion resistance index is 22mg, and the pull-out bonding strength is 6.9MPa.

Abstract

The invention discloses an anti-crack durable hot-melt road marking coating and a preparation method thereof.The anti-crack durable hot-melt road marking coating is prepared from 10-30 parts of polybutylene modified C5 petroleum resin, 1-3 parts of EVA hot melt adhesive, 1-5 parts of PE wax, 3-8 parts of titanium dioxide, 20-40 parts of calcium carbonate, 18-25 parts of glass beads, 1-8 parts of plasticizer, 10-30 parts of quartz sand and 2-8 parts of ZTA-VE high-elastic anti-crack particles, the parts are parts by mass. The road marking coating disclosed by the invention has the advantages of good night reflective property, friction resistance, water resistance, acid and alkali resistance and good pavement adhesion, is suitable for pavements of highways, expressways and urban roads, has a better reflective effect than that of a common hot-melt marking coating under the irradiation of automobile lamps at night, enables road marking to be more obvious, and is beneficial to improving the safety of night driving; the coating has very high strength durability, weather resistance, drawing bonding strength and crack resistance, and the pavement is almost free of cracks after one year of construction; the preparation method is simple and does not need special equipment.

Description

technical field [0001] The invention relates to a crack-resistant and durable hot-melt road marking paint and a preparation method thereof, belonging to the technical field of hot-melt road marking paint. Background technique [0002] Road markings are a kind of safety mark and a "special voice". The traffic safety management department uses road marking paint to delineate vehicle driving lanes and channelize traffic, so as to strengthen traffic safety management, reduce vehicle and personal accidents and beautify the city purpose of the road. Road traffic markings are mainly drawn on the road surface, which are exposed to the sun, rain, wind, snow and ice, and are subjected to the impact and wear of vehicles, so there are strict requirements on their performance. First of all, it requires short drying time and simple operation to reduce traffic interference; secondly, it requires strong reflective ability, bright color, and strong reflective degree, so that it has good vis...
