Embodiment 1

[0045] This embodiment provides a kind of luminous warning type road reflective paint, is made up of primer and finish paint;

[0046] The primer includes a primer A component and a primer B component. By weight percentage, the primer A component includes: two-component room temperature curing acrylic resin (Japan DIC 52-204ZS, molecular weight is about 15000) 30%, Luminous powder (alkaline earth aluminate) 15%, leveling agent (BYK361N) 1%, wetting and dispersing agent (OBYK-180) 0.5%, first defoamer (BYK-A515) 0.5%, drier ( Cobalt isooctanoate) 0.5%, toner (titanium dioxide) 2.5%, reactive diluent (methyl methacrylate) 50%, primer B component includes: initiator (benzoyl peroxide) 50%, reactive diluent Agent (methyl methacrylate) 50%;

[0047] The topcoat includes topcoat A component and topcoat B component. In terms of weight percentage, topcoat A component includes: two-component room temperature curing fluorocarbon resin (Shanghai Fluorine New Material 401 with a hydroxyl...

Embodiment 2

[0055] This embodiment provides a kind of luminous warning type road reflective paint, is made up of primer and finish paint;

[0056] The primer includes primer A component and primer B component, and the content of each component is shown in Table 1.

[0057] The construction method provided by this embodiment is consistent with Example 1, the difference is that in the process of preparing the primer, the mass ratio of the primer A component to the primer B component is 1:0.005, after curing, the dry film of the primer The thickness is 300μm; in the process of preparing the topcoat, the mass ratio of component A of the topcoat to component B of the topcoat is 1:0.1, and after curing, the dry film thickness of the topcoat is 60μm. The performance of the coating was tested after 72 hours of construction, and the test results are shown in Table 2.

Embodiment 3

[0059] This embodiment provides a kind of luminous warning type road reflective paint, is made up of primer and finish paint;

[0060] The primer includes primer A component and primer B component, and the content of each component is shown in Table 1.

[0061] The construction method provided by this embodiment is consistent with Example 1, the difference is that in the process of preparing the primer, the mass ratio of the primer A component to the primer B component is 1:0.02, after curing, the dry film of the primer The thickness is 100μm; in the process of preparing the topcoat, the mass ratio of topcoat A component to topcoat B component is 1:0.3, and after curing, the dry film thickness of the topcoat is 40μm. The performance of the coating was tested after 72 hours of construction, and the test results are shown in Table 2.

Abstract

The invention relates to a luminous warning road reflective paint and a construction method thereof. The coating is composed of a primer and a topcoat; by weight percentage, the A component of the primer includes: two-component room temperature curing acrylic resin, luminous powder, leveling agent, wetting and dispersing agent, the first defoamer, catalyst Drying agent, toner, reactive diluent, primer B component includes: initiator, reactive diluent; topcoat A component includes: two-component room temperature curing fluorocarbon resin, glass beads, anti-settling agent, second 2. Defoamer, drier, solvent; topcoat component B includes: curing agent, thinner. The coating formed by the coating of the present invention has a good surface state, is not easily polluted, has good reflection effect, strong adhesion, and the marking line is not easily deformed, and has good stability at the same time, which is beneficial to reducing the later maintenance cost.

Description

technical field [0001] The invention relates to the technical field of reflective paint, in particular to a luminous warning road reflective paint and a construction method thereof. Background technique [0002] At present, in terms of road traffic safety, it mainly includes two systems. One is the safety warning system, which mainly relies on signs, signs, safety barrels, markings, reflective outline marks, road stud reflective cursors, reflective film, reflective Aluminum plates, reflective paint on the sides of tunnel cable trenches, etc. are used to warn and guide pedestrians and vehicles; the second is the safety protection system, which mainly relies on the forced isolation of some obstacles or the correction of improper driving behavior to protect life and property. It is to use steel plate guardrail and concrete guardrail to protect driving safety. [0003] Among them, road traffic markings belong to the infrastructure in road traffic and are an indispensable part o...
