Water-based underwater reflecting roads sign coating

Abstract

The invention discloses a water-based underwater light-reflection road marking coating material, which comprises the following compositions in percentage by mass: 8.00 to 12.00 percent of rutile type titanium pigment, 0.30 to 0.50 percent of poly acrylate pigment dispersing agent, 0.10 to 0.14 percent of sodium tripolyphosphate, 2.00 to 2.60 percent of alcohol, 0.20 to 0.40 percent of fatty acid lower alcohol acid ester, 15.00 to 25.00 percent of glass bead, 20.00 to 40.00 percent of quartz sand, 8.00 to 12.00 percent of calcite in powder, 0.08 to 0.12 percent of Kathon, 0.10 to 0.30 percent of ethyl cellulose ether, 18.00 to 28.00 percent of acrylic acid latex base material, 0.20 to 0.40 percent of ammonia water and 2.68 to 3.88 percent of water. The marking coating material has convenient construction, high construction safety, excellent underwater light reflection, environment protection, and is nontoxic and noninflammable; moreover, the marking coating material can be directly coated again on a solvent type or hot melt type marking, thereby reducing cost and increasing construction efficiency.

Description

【Technical field】 [0001] The invention relates to the field of municipal road engineering, in particular to a road reflective marking paint, in particular to a water-based underwater reflective road marking paint. 【Background technique】 [0002] With the rapid development of national highways, there is an urgent need to develop road marking paints with good performance and more functions to meet the requirements of improving all-weather high visibility, environmental protection, durability, and construction convenience. [0003] At present, there are many road marking materials used for traffic safety facilities in China, such as solvent-based and hot-melt road marking paints. But all there are many defectives in these marking paints. [0004] Hot-melt marking paint mainly has the following defects: [0005] 1. It needs to be heated to about 180°C during construction, which may easily cause scald accidents for construction personnel and poor construction safety; [0006] ...

AI Technical Summary

Problems solved by technology

[0005] 1. It needs to be heated to about 180°C during construction, which may easily cause scald accidents for construction personnel and poor construction safety;

[0006] 2. Requires repeated heating, high energy consumption, and inconvenient construction;

[0007] 3. The microbeads are easy to fall off, and the reflective effect at night is not long-lasting. Choose 1.50RI glass beads, and the marking line under the water film at night has no reflective function;

[0008] 4. The content of volatile organic compounds in the construction seriously exceeds the standard, which will cause certain harm and pollution to the human body and the environment;

[0009] 5. The old line needs to be removed when repainting, which increases the cost and reduces the construction efficiency

[0011] 1. The glass beads are easy to fall off, the reflective effect at night is not good, the service life is short, and there is no underwater reflective function;

[0012] 2. In order to make the reflective glass beads protrude from the water surface, the glass beads with larger particle size are selected, but because of the larger moment when the force is applied, it is easier to fall off the marking surface during the use of the marking line;

[0013] 3. The solvent content in the paint is more than 650 g / liter of paint, the volatile organic compounds are seriously exceeded, the toxicity is high, and the toxic gas released has certain harm and pollution to the human body and the environment
