Problems solved by technology

[0004] However, there are still two problems in this method: on the one hand, the improvement of surface smoothness will reduce the surface anti-slip coefficient of road markings, prolong the braking distance of cars or cause pedestrians to slip, and increase safety hazards; on the other hand, its The anti-fouling effect is related to the surface structure. With the increase of the use time of the road markings, the surface structure will be damaged, which will inevitably make the road markings lose the anti-fouling effect and become equally easy to get dirty
[0005] Therefore, inventing a marking paint with low surface smoothness and continuous anti-fouling can effectively solve the above-mentioned problems in the industry

Abstract

The invention discloses a self-cleaning road marking coating. 50-150 parts by mass of modified acrylic resin, 0.1-2 parts by mass of an accelerant, 1-10 parts by mass of inert oil and 10-50 parts by mass of a low-boiling-point and low-surface-tension solvent are mixed to form a component A; and 50-150 parts by mass of modified acrylic resin, 1-10 parts by mass of a curing agent, 1-10 parts by mass of inert oil and 10-50 parts by mass of a low-boiling-point and low-surface-tension solvent are mixed to form a component B. The modified acrylic resin is a mixture obtained by taking active monomer methyl methacrylate, butyl acrylate and hydroxypropyl methacrylate dissolved solid acrylic resin as a dispersion medium, adding inorganic filler and pigment nano titanium dioxide, and modifying the inorganic filler and the nano titanium dioxide with a silane coupling agent. On the premise of not increasing the surface smoothness of the road marking, the coating can realize the continuous and long-lasting self-cleaning effect of the road marking.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to a road marking paint, in particular to a road marking paint with self-cleaning function and a preparation method of the road marking paint. Background technique [0002] Road markings are an important part of road safety facilities. Because of its traffic guidance function, the observation effect of road markings will affect the driver's driving experience, thereby affecting safety. If the road markings are easily dirty, the indication effect of the markings will drop sharply in a short period of time, and the guiding function will be reduced, thus causing potential safety hazards. [0003] In order to improve the problem that road markings are easy to get dirty, the current common solution is to improve the anti-fouling effect by improving the surface smoothness of the marking paint. [0004] However, there are still two problems in this method: on the one hand, the improvement...
