Embodiment 1

[0068] Divide the high-efficiency thickener XQZJ-100 (according to mass percentage: 85% organic bentonite, 10% organic kaolin, and 5% fumed silica) of 0.4% of the total amount of paint into two equal parts, and add them to groups A and B respectively After stirring evenly, add 2% benzoyl peroxide of the total amount of paint to component B and stir evenly with an electric mixer at low speed, put component A and component B added with 2% benzoyl peroxide In different containers isolated from each other, mix components A and B at a ratio of 1:1 as evenly as possible, and apply it on the test panel. Add American Standard No. 2 glass beads and American Standard No. 3 glass beads with a roundness rate of 90% and a refractive index of 1.9 into the corresponding hoppers, and adjust the output ratio to 3:4. Sprinkle the glass beads on the surface before the paint solidifies. Sprinkle the beads on the surface of the coating. Specifically, first sprinkle the American Standard No. 3 glas...

Embodiment 2

[0101] According to the composition of the paint and surface sprinkle glass beads described in Example 1 and the surface sprinkle amount forming marking line, under the conditions of different temperatures and different curing agent dosages, with the embedding degree between 55%-65% as the target, determine different The optimum dosage of curing agent at the temperature is shown in Table 3 for the results.

[0102] Table 3 Curing agent dosage at different temperatures

[0103] Ambient temperature (℃) 5℃ 10℃ 15℃ 20℃ 25℃ 30℃ 35℃ Curing agent dosage (%) 3.7 3.7 2.9 2.4 2.0 1.75 1.4

[0104]When constructing the marking line, you can refer to the local climate conditions and choose the appropriate amount of curing agent to achieve the best hardening time and retroreflection coefficient of the marking line.

Abstract

The application provides a PMMA-type two-component marking paint. In wt%, component A includes: 25-30% of the first liquid PMMA resin, 6-10% of rutile titanium dioxide, 28-33% of calcium powder, 0.2-0.5% accelerator, 2-5% additive, 32-35% of the first internal mixing glass beads; B component includes: 25-30% of the second liquid PMMA resin, 6-10% of rutile titanium dioxide, calcium 28‑33% powder, 2‑5% additives, 32‑35% second internally mixed glass beads; the roundness rate of the first and second internally mixed glass beads is ≥90%, the refractive index is 1.9‑2.1, and the particle size distribution 0.15mm‑0.3mm: 15%‑40%, 0.3mm‑0.6mm: 50%‑80%, 0.6mm‑0.85mm: 5%‑15%. The marking line prepared by the paint has better continuous light reflection and durability.

Description

technical field [0001] The invention relates to a marking material and a construction process for road markings, in particular to a PMMA-type two-component marking paint, an environmentally friendly and durable two-component marking material using the paint, and a road marking using the material Construction method. Background technique [0002] Road markings can provide drivers and pedestrians with sufficient reflection information, which has a significant effect on reducing traffic accidents and improving vehicle traffic efficiency. The road marking paint is laid on the hardened road surface after construction to achieve the purpose of planning and warning the driving route. Pavement 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 its performance. First of all, it requires short drying time and simple operation to reduce traffic...
