Problems solved by technology

However, the reactive diluents in solvent-free epoxy coatings still have volatile, toxic and irritating odors during the production and construction of the coatings, which can cause harm to the human body. These are often ignored during the production of coatings
[0004] The marking paint products currently used in the market are not environmentally friendly, have low solid content and contain volatile solvents. The coating is thick during construction and needs to be marked 3-4 times before it can be formed, which increases construction costs and labor. The color of the line paint is not bright, the surface is flat, and the gloss is not good
Moreover, the existing marking paint products generally reduce costs and reflect their color and performance by adding toxic and harmful metal elements such as lead, mercury, cadmium, arsenic and hexavalent chromium, which will seriously endanger production and construction. personal safety of personnel

Abstract

The invention discloses an aqueous road marking paint. The aqueous road marking paint comprises the following components by weight percentage: 15-20% of a polyester composite acrylic emulsion, 25-28%of glass beads, 15-20% of titanium dioxide, 12-15% of powdered steatile, 1-2% of an anti-settling agent, 0.5-1% of an antifreezing agent, 0.5-0.8% of a dispersant, 0.1-0.2% of a wetting agent, 0.3-0.5% of a defoamer, 0.2-0.3% of a pH conditioning agent, 0.2-0.6% of an antiseptic, 0.2-0.5%of a thickener, and 20-25% of water. The aqueous road marking paint of the invention has excellent wear resistance and water resistance, and has wide adhesion, the high refractive index glass microbead achieves obvious reflective warning effect, and the paint is suitable for road making for asphalt or cement concrete.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based road marking paint and a preparation method thereof. Background technique [0002] At present, my country's liner paint is mainly hot-melt type based on C5 petroleum resin and rosin-modified resin and room temperature solvent type based on polyacrylate resin. With the development of the times and the advancement of science and technology, this type of coating has developed from a single normal temperature solvent type to a normal temperature solvent type, heating solvent type, hot melt type and environmentally friendly coatings. [0003] Hot-melt coatings have disadvantages such as slow construction speed, poor construction conditions, and difficulty in rerouting. Solvent-based coatings contain a large amount of volatile organic compounds (VOC). When the paint film dries, it will cause great pollution and harm to the surrounding environment. Environmental requirem...
