Description
Technical Field
The invention relates to the technical field of road marking paint, in particular to an environment-friendly wear-resistant hot-melt road marking paint and a preparation method thereof.
Background
The road traffic marking has the functions of guiding traffic and transmitting standard information. The road marking should have good visibility and retroreflective properties. The hot melt marking paint has the advantages of short drying time, convenient construction, good wear resistance and no organic solvent, and has higher occupancy rate in the road traffic marking paint market in China. The hot melt marking paint is a solid powder mixture which is prepared by mixing and stirring resin serving as a binding material, pigment, filler, reflecting material, auxiliary agent and the like. The bonding material adopted in the market at present is mostly C5 resin, is prepared by preprocessing, polymerizing, flash evaporating and other processes of cracking C5 olefin which is a byproduct of an ethylene device, and is a petrochemical product. The glass bead has the defects of low softening point, easiness in cracking and weak bonding strength between a matrix and the glass beads. The hot melt road marking using the C5 resin as the bonding material system has the problems of easy softening at high temperature in summer, easy pollution, easy falling of glass beads, quick attenuation of luminosity performance and the like. In addition, the production process of the hot-melt marking paint uses a large amount of C5 petrochemical products, which does not meet the requirement of low carbon and environmental protection, and the brought environmental pollution is paid attention to. There is therefore an urgent need for an environmentally friendly abrasion resistant road marking coating that is environmentally friendly and has excellent compressive strength, abrasion resistance, weather resistance, and thermal deformation resistance.
The patent CN104387891A proposes an environment-friendly hot melt marking paint, and the invention uses modified soybean oil as a plasticizer to replace DOP, thereby achieving the environment-friendly effect. However, the proportion of the plasticizer in the hot melt marking system is 1-2%, the content is small, and the problem of environmental protection of the paint is not fundamentally changed by replacing only a small amount of plasticizer. The paint bonding material still uses C5 petrochemical products, belongs to non-renewable resources, and therefore, an environment-friendly bonding material capable of partially replacing C5 resin is sought, and the requirement of low carbon in the future is met.
The invention provides a reflective hot-melt marking paint and a preparation method thereof, wherein the marking paint prepared by taking C5 resin as a bonding material, paraffin, EVA and white oil as auxiliary agents and quartz sand and heavy calcium powder as fillers has strong adhesive force and good wear resistance. The invention mainly reduces the non-sticking tire drying time of the marking paint by controlling the content of the C5 resin, improves the mechanical property and achieves the purpose of rapidly opening traffic. However, the C5 resin lacks a polar functional group on the molecular structure, has low softening point and poor wear resistance, can not change the determination of insufficient overall stability and easy softening at high temperature in summer, and has limited aspects of improving the dirt resistance of a coating system and the bonding performance of the coating system and glass beads. Therefore, we propose an environment-friendly wear-resistant hot-melt road marking paint and a preparation method thereof to solve the problems.

TABLE 1 examples 1-4 component mixing ratios
The hot melt marking paints of examples 1 to 4 and comparative examples 1 to 2 were tested as follows with reference to pavement marking paint (JT/T280-2022), and the measurement results are shown in Table 2:
TABLE 2 coating Performance test results for examples 1-4
As is clear from the table, the environment-friendly wear-resistant hot-melt road marking paint disclosed by the invention has excellent compression strength, wear resistance and thermal deformation resistance, and the retroreflection brightness coefficient after 24 months is above 350 mcd.m-2.lx-1 after marking, which is obviously higher than that of a comparative example. The result shows that after the modified rosin resin is used for replacing part of C5 resin, the consumption of petrochemical products in a coating system is reduced, the problem of fast attenuation of marked lines is solved, and the service life of the marked lines is obviously prolonged.
The preparation method of the environment-friendly wear-resistant hot-melt road marking paint comprises the following steps: firstly, accurately weighing the components according to the proportion of each component, and paying attention to the components of the auxiliary agent in the coating; adding titanium dioxide, heavy calcium powder, premixed glass beads and other components according to a certain sequence, respectively adding the components into a mixer, uniformly mixing, and adding modified rosin resin, C5 resin, polyethylene wax, an antioxidant and EVA (ethylene-vinyl acetate copolymer) while stirring; after being mixed evenly, the liquid plasticizer dioctyl phthalate and the modified epoxidized soybean oil are added, and then the mixture is stirred continuously until being even. The mixing process needs to pay attention to the dispersing time, and ensures that the uniformity of a coating system is primarily achieved after the dispersing. After the material mixing is finished, EVA tape packaging is adopted, and packaging can be directly put into a hot melting kettle together during on-site construction melting, so that the packaging is not required to be unpacked.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
