Problems solved by technology

Many scholars have carried out research on the performance optimization of road marking paint, but based on the harsh environment such as large temperature difference and strong ultraviolet radiation in high altitude areas, there is almost no way to optimize the design of road marking paint.
And there is little research on the cooling construction of hot-melt coatings
[0005] Aiming at a series of cracking and peeling problems in road markings in high-altitude areas, the present invention provides a cooling system that can reduce the melting construction temperature by 40-60°C, has anti-ultraviolet aging, high toughness, high durability, and strong low-temperature cracking resistance. Formula and preparation method of high-performance road marking paint

preparation example Construction

[0025] The preparation method includes the following steps:

[0026] The binder, the filler, the pigment, the reflective material, the plasticizer, the elasticizer, the warm-mixing agent and the light-shielding agent are dry-mixed and uniformly mixed at 160° C. After heating for 15 minutes, when the coating is initially melted, the rheological agent is added to mix quickly and uniformly.

Embodiment 1

[0028] A preparation method of a cooling type high-performance road hot-melt marking paint in high-altitude areas, the specific steps are as follows:

[0029] 1) Weigh each raw material in the following proportions: 14% of binder, 45% of filler, 8% of pigment, 23% of reflective glass beads, 1% of plasticizer (No. 1-1), 2% (No. 1- 2), 3% (No. 1-3), elasticizer 8%, rheology agent 2%, warm mix agent 2%, light shielding agent 1%;

[0030] 2) Dry-mix the binder, fillers, pigments, reflective materials, plasticizers, elasticizers, warm-mixing agents and light-shielding agents evenly, and heat at 160°C for 15 minutes. When the coating is initially melted, add rheology agent and mix quickly and evenly , adjust the melt fluidity of the coating to be less than 45s (mixing time is about 5min), and obtain a high-altitude cooling high-performance road hot-melt marking coating, which can be directly coated on the road.

Abstract

The invention provides a cooling type high-performance road marking hot melt coating for high-altitude areas and a preparation method thereof, and relates to the technical field of road marking materials. The cooling type high-performance road marking hot-melt coating for the high-altitude area comprises the following components in percentage by mass: 10-18% of a cementing material, 40-60% of a filler, 3-8% of a pigment, 15-23% of a reflective material, 0.5-3% of a plasticizer, 4-12% of an elasticizer, 1-4% of a rheological agent, 0.5-3% of a warm mixing agent and 0.5-2% of a light screening agent. According to the obtained cooling type high-performance road marking coating for the high-altitude areas, the ultraviolet resistance and the low-temperature cracking resistance can be remarkably improved on the premise that the good pavement performance of the road marking coating is maintained and effectively improved, and the cooling type high-performance road marking coating has important application and popularization significance in the high-altitude areas.

Description

technical field [0001] The invention relates to the technical field of road marking materials, in particular to a high-altitude cooling type high-performance hot-melt paint for road markings and a preparation method thereof. Background technique [0002] The role of road marking paint is to guide the driving of motor vehicles and non-motor vehicles on the road. Hot-melt marking is the leading road marking coating in my country with low cost, good wear resistance and convenient construction. The main component of hot-melt coating is thermoplastic resin (petroleum resin, etc.), which is characterized by bonding sex, quick drying. Synthetic resin can combine coloring pigments, extender pigments, reflective materials, etc., adhere to the road surface, hot-melt bonding, make the coating have a suitable viscosity when melted, and dry to form a film after cooling. The production cycle is short, the production cost is relatively low, the production process is pollution-free, and it...
