Problems solved by technology

[0005] 1) Cause microcrystalline ceramic beads to fall off from the surface of road marking paint;
[0006] 2) The glass beads on the microcrystalline ceramic beads are detached from the surface of the microcrystalline ceramic beads, leaving only the ceramic particles
It is impossible to solve the problem that the reflective material falls off due to abrasion, which significantly reduces the reflective effect and service life of the markings; and it is obvious that the three layers of road marking paint are constructed and prepared separately, and the components of each layer are relatively complicated. Increased construction difficulty, it is difficult to adapt to the current road construction requirements for rapid construction

Embodiment 1

[0045] In order to realize the "suspension" of irregular ceramic particles in the matrix of road marking paint and provide mosaic sites for reflective materials, the present invention screens the fillers. Different types of fillers and particle sizes were used to form road marking paints with irregular ceramic particles (particle size 1.0-1.5mm), and the settlement effect of irregular ceramic particles in road marking paints composed of different fillers was investigated (drying rear micrometer measurement), the method is as follows:

[0046] 1) First add 16 parts by weight of C5 petroleum resin, 3 parts by weight of rosin maleic anhydride polyol ester, 20 parts by weight of internally mixed glass microspheres and 20 parts by weight of filler in the stirring tank and stir evenly; then add 35 parts by weight of irregular ceramic particles (particle size is 1.0-1.5 mm), 5 parts by weight of calcium halophosphate fluorescent powder, and finally add 10 parts by weight of pigment t...

Embodiment 2

[0055] With sequence 14 in embodiment 1 as filler, reflective material glass beads and / or 3M are sprinkled on the surface of road markings TM All-weather microcrystalline ceramic beads (90S, white), test 1) the wear resistance of road markings, and evaluate the bonding force between reflective materials and road markings; 2) test the change value of the retroreflective brightness coefficient with the service cycle to measure the actual reflection Performance, which can evaluate the actual service life of the reflective material; the specific method is as follows:

[0056] 1) First add 16 parts by weight of C5 petroleum resin, 3 parts by weight of rosin maleic anhydride polyol ester, 20 parts by weight of internally mixed glass beads and 20 parts by weight of filler (quartz sand 400-500 mesh, barium sulfate and dolomite) in the stirred tank Mother powder is 200-300 mesh, the three are equal in weight) and stirred evenly; then add 35 parts by weight of irregular ceramic particle...

Embodiment 3

[0066] Compared with Example 2, Example 3 does not add internally mixed glass beads when preparing the road marking paint, so as to remove the influence of internally mixed glass beads on the coefficient of retroreflection brightness, and detect the change of the coefficient of retroreflective brightness with the service cycle The value is used to measure the actual reflective performance, so as to measure the degree of shedding of the reflective material sprinkled on the road markings. The results are shown in Table 3:

[0068]

[0069]

[0070] Note: 3M microcrystalline ceramic beads-D1 refers to the use of 3M microcrystalline ceramic beads as the reflective material, but the particle size of irregular ceramic particles is reduced from 1.0-1.5mm to 0.1-0.3mm.

[0071] The retroreflection brightness coefficient in the above Table 3 is the dry state retroref...

Abstract

The invention belongs to the technical field of road marking materials, and more specifically relates to a durable reflective self-layering road marking paint and a preparation method thereof. The present invention adds particle size to the road marking paint that 15-20 parts of C5 petroleum resin, rosin maleic anhydride polyol ester, inner mixing glass microsphere, fluorescent powder, pigment, ethylene-vinyl acetate copolymer and plasticizer form Irregular ceramic particles of 1.0-1.5mm, and the fillers are screened, so that the road marking paint can play the role of "self-layering", and the irregular ceramic particles "suspend" on the road marking paint, which is a reflective material It provides a chimeric site, which solves the defect that the reflective material is easy to fall off from the road marking paint matrix, so that the reflective material has a long-lasting reflective performance; the addition of phosphor solves the defect that the road marking paint does not have self-luminescence. All performances of the product prepared by the invention meet the requirements, and the comprehensive performance is excellent.

Description

technical field [0001] The invention belongs to the technical field of road marking materials, and more specifically relates to a durable reflective self-layering road marking paint and a preparation method thereof. Background technique [0002] Road markings are one of the important safety facilities of road traffic. They are used to regulate the passage of vehicles and pedestrians, so that they can go their own way without interfering with each other, so as to ensure safe and smooth traffic. Traditional road markings have poor reflective performance at night or in rainy days. Usually, glass beads are sprinkled on the surface immediately after the road marking paint coating is applied during road marking construction. The glass beads sprinkled on the surface are distributed in the road marking paint. The surface and part of the car are exposed to the air, so the light from the car lights driving on the road can achieve a reflective effect after it hits the road markings. ...
