Problems solved by technology

The traditional marking paint has low bonding force with the road surface, and the marking line will fall off the road surface when it is subjected to rutting, high temperature, low temperature, snow plowing, etc., and the service life of the marking line is short; it also has antifouling and self-cleaning properties Poor, easy to be stained with dirt and blackened, it is necessary to repaint and refurbish the markings in a short period of time; in addition, because the markings also need to mark the road surface at night, in rainy days and other environments with poor lighting conditions, markings are usually required It has a certain reflective performance. At present, the reflective performance of the marking is usually given by mixing in the marking paint or spraying glass beads on the surface during the formation of the marking, so as to improve the retroreflective performance of the marking paint, improve the luminous effect, and prolong the life of the marking. The use performance of road markings, but because the glass beads are inorganic substances, they are not compatible with the marking paint of organic materials, and they are easy to fall off during use, resulting in a decrease in the reflective performance of the markings
[0003] Therefore, it is necessary to improve the formula composition, preparation method and construction method of marking lines to overcome the defects that existing marking paints are easy to fall off, easy to be contaminated with dirt, and reflective glass beads are easy to fall off

preparation example Construction

[0035] The modified glass microspheres adopted in the following examples are prepared by the following preparation method: specific operation steps:

[0036] 1) Prepare organic modifier solution: prepare organic modifier solvent with water and alcohol at a ratio of 1:8-10; then use organic acid to adjust the pH to acidic, and add 5-20% The coupling agent until transparent, then add 0.5-5% surfactant, then add 2-10% film-forming agent, heat up to 40-50°C, and stir at 500-4000 rpm for 0.5-2 hours;

[0037] 2) Modified glass beads: disperse the glass beads into the organic modification solution prepared in step 1), and stir at 500-4000 rpm for 1-3 hours at a temperature of 40-50°C;

[0038] 3) Removing the residual modifying agent: filtering the mixed solution of glass microbeads modified in step 2), washing the filtered microbeads with hot water, stirring for 1 to 5 hours and filtering;

[0039] 4) Drying: vacuum-dry the glass microspheres treated in step 3) at a temperature of...

Abstract

The invention relates to the technical field of road reticule coatings, in particular to a multi-component spray reticule coating as well as a preparation method and application thereof. The coating is prepared from a component A, a component B and a solid particle material C, wherein the component A is prepared from epoxy resin, hydroxyl-terminated polybutadiene liquid rubber, adipic acid, 2,6-methyl diisocyanate, 1,6-hexamethylene diisocyanate, stannous octoate, polycaprolactone polyol, dichloromethane, urea resin, lithium silicate and a film forming additive; the component B is prepared from self-crosslinked elastoacrylate emulsion, polydimethylsiloxane, diethylenetriamine and dichloromethane; the component C is prepared from nanosilicon dioxide, calcium carbonate, talcum powder, pigment and modified glass micro beads. A reticule formed by the coating is high in binding force with a pavement, is not easy to crack and fade, and has extremely high self-cleaning antifouling property. Furthermore, the surfaces of the modified glass micro beads in the coating are grafted with coupling agents and film forming agents, so that the shortcoming that a conventional luminous glass micro bead is easy to fall off is overcome.

Description

technical field [0001] The invention relates to the technical field of road marking paint, in particular to a multi-component spraying marking paint and its preparation method and application. Background technique [0002] Road demarcation lines, crosswalks and seat belt markings on highways, expressways, urban roads, airports and docks are important signs for traffic flow, vehicle operation, pedestrian safety and traffic violation accidents. Due to the sharp increase in road paving rate, higher requirements are put forward for road marking paints, and compared with paints in other fields, the application environment of road marking paints is more severe, not only to withstand environmental temperature changes, sun and rain Waiting for the test, but also face the rolling and friction from the wheels. The traditional marking paint has low bonding force with the road surface, and the marking line will fall off the road surface when it is subjected to rutting, high temperature...
