Problems solved by technology

However, in the current construction process of reflective marking materials, when adding glass beads, there are disadvantages, that is, the time of adding glass beads during the construction process is not easy to control
If the adding time is too early, the beads cannot be completely integrated into the resin matrix, which will reduce the reflective effect of the material; if the adding time is too late, the beads will float on the surface of the resin and fall off easily

Embodiment 1

[0024] The preparation method of the road marking patch, the specific steps are as follows.

[0025] Step 1, coating of artificially dyed glass microspheres.

[0026] (1) Preparation of colored polyurethane prepolymer: Take 8 parts by mass of dipropylene glycol and place it in a three-necked flask equipped with an electric mixer, a constant pressure dropping funnel, a thermometer, and a drying tube; depressurize to 0.04MPa at 110°C After removing water for 2 hours, cool naturally to 65°C, add 20 parts by mass of acetone solution with a concentration of 30% for dilution, and simultaneously turn on the electric mixer and stir at 1000 rpm. Then 2 parts by mass of dibutyltin dilaurate are added to the diluent; 20 parts by mass of toluene diisocyanate is diluted with 20 parts by mass of acetone with a concentration of 30%, and all of them are added to the there-necked flask, while adding 10 parts by mass of lead Chrome yellow powder and 6 parts by mass of hydroxy silicone oil were...

Embodiment 2

[0031] (1) Preparation of colored polyurethane prepolymer: Take 7 parts by mass of dipropylene glycol and place it in a three-necked flask equipped with an electric mixer, a constant pressure dropping funnel, a thermometer, and a drying tube; depressurize to 0.03MPa at 110°C After removing water for 2 hours, cool naturally to 65° C., add 30 parts by mass of acetone solution with a concentration of 30% for dilution, and simultaneously turn on the electric mixer and stir at 1500 rpm. Then 3 parts by mass of dibutyltin dilaurate are added to the diluent; 25 parts by mass of toluene diisocyanate is diluted with 30 parts by mass of acetone with a concentration of 30% and then all added to the three-necked flask. Iron yellow powder and 7 parts by mass of hydroxy silicone oil were stirred at 65° C. at 2000 rpm for 15 minutes, and cooled to room temperature to obtain a colored polyurethane prepolymer containing silicon.

[0032] (2) Coating of glass beads: first take 20 parts by mass ...

Abstract

The invention belongs to the technical field of coating, and particularly relates to a road marking patch and a preparation method thereof. The road marking patch is mainly formed by compounding artificially stained glass beads coated with polyurethane and water-borne epoxy resin, takes fluorinated graphene as a filler, and takes gridding cloth as a substrate material. The method overcomes the disadvantage that the time for adding glass beads during construction of the traditional reflective marking materials is not easy to control, meanwhile further enhances the water resistance property, alkaline resistance property, non-skid property and wear resistance property of materials, and greatly improves the economic value of road markings.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a road marking sticker and a preparation method thereof. Background technique [0002] Road traffic markings are traffic safety facilities composed of various lines, arrows, characters, facade marks, raised road signs and contour marks marked on the road surface. Its role is to control and guide traffic. Road traffic markings are mainly drawn on the road surface, which are exposed to the sun, rain, wind, snow and ice, and are subjected to the impact and wear of vehicles, so there are strict requirements on their performance. First of all, the construction operation should be simple to reduce traffic interference; secondly, it should have strong reflection ability, bright color, and strong reflective degree, so that it can have good visibility during the day and night; thirdly, it should have anti-slip and abrasion resistance to ensure driving safety and longevity. [0003] At...
