Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the advancement of the car depends on the friction generated by the wheels and the road surface, and this friction has high requirements for the wear resistance of the performance. The strength is only 14.5Mpa, and the wear resistance is poor. After the marking line is worn out, its reflective performance is reduced. When the car is driving on a rainy night, it is easy to cause traffic accidents due to the poor indication effect of the marking line

Embodiment 1

[0038] Table 1 is the component and quality thereof of a kind of road marking paint of embodiment 1

[0039]

[0040] Wherein, the preparation method of modified epoxy resin is:

[0041] 1) Add 20 grams of sodium hydroxide to 980mL of water, stir until the sodium hydroxide is completely dissolved, and adjust the temperature of the system to 70°C;

[0042] 2) Add 57.06 grams of bisphenol A to step 1), stir and dissolve completely, add 50 grams of nano-calcium carbonate, and continue stirring;

[0043] 3) After the system temperature drops to 50°C, add 46.26 g of epichlorohydrin, then gradually raise the system temperature to 100°C, and continue stirring for 2 hours;

[0044] 4) After the reaction in step 3) ends, add 500mL cold water, after the resin sinks, remove the upper waste water;

[0045] 5) Continue to add water to step 4), increase the temperature and stir, heat the system to boil and wash for 20 minutes, then add water to continue washing until there is no chlori...

Abstract

The invention relates to a road marking coating and a preparation method thereof. The road marking coating comprises the following components in parts by mass: 30-40 parts of modified epoxy resin, 50-60 parts of extender pigment, 10-15 parts of titanium dioxide, 20-30 parts of glass beads, 3-5 parts of a plasticizer, 5-10 parts of quartz sand, 2-3 parts of an ethylene-vinyl acetate copolymer, 1-3parts of polyethylene wax, 2-4 parts of an adhesion promoter and 1-2 parts of an ultraviolet light absorber. The road marking coating provided by the invention is good in wear resistance and high in compressive strength, and then the added glass beads can reflect light continuously, so that the indication effect at rain nights is good, safety of vehicles during running at rain nights can be improved, and probability of traffic accidents is reduced.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a road marking coating and a preparation method thereof. Background technique [0002] Road marking paint is a paint that is painted on the road surface to indicate traffic. With the rapid development of my country's transportation industry, the demand for road marking paint is gradually increasing. Road marking paints are generally divided into four categories: solvent-based, hot-melt, two-component, and water-based. Solvent-based road marking paints mostly use chlorinated rubber, epoxy resin and acrylic resin as film-forming substances, which often require a large amount of organic solvents, and then the release of organic solvents will cause environmental pollution, so its market share is gradually decreasing. Hot-melt road marking paints generally use petroleum resins, natural resins, etc. as film-forming substances. Coating has the characteristics of short drying time, go...
