A kind of water-based cold-melt road marking paint and preparation method thereof

Abstract

The invention relates to the technical field of coating, and discloses water-based cold cut road marking coating which comprises the following components in parts by weight: 4.87 parts of water, 0.03 part of a fungicide, 1.5 parts of a water-based wax emulsion, 3 parts of ethanol, 0.4 part of a water-based dispersant, 27 parts of a water-based acrylic emulsion, 1-2 parts of organic bentonite, 1 part of a water-based drier, 5-8 parts of a pigment, 15 parts of a 40-60 mesh of glass bead, 30 parts of a 80-120 mesh of glass bead, 8.2 parts of white corundum, and 3 parts of a coalescing agent. The invention further discloses a preparation method of the water-based cold cut road marking coating. The preparation method comprises the step of uniformly mixing all the components. The water-based cold cut road marking coating combines the advantages of solvent marking coating and heat fusing marking coating, such as convenient and fast construction, environment protection, no pollution, ideal marking thickness, high drying speed and long service life, and is an ideal product replacing the solvent marking coating and the heat fusing marking coating.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a road marking paint, in particular to a water-based cold-soluble road marking paint and a preparation method thereof. Background technique [0002] In traffic driving, standardized road markings define the driving routes of various vehicles. Vehicles traveling at high speed at night need clear and bright reflective lane guidance to ensure that everyone goes their own way and drives safely. [0003] Pavement markings were born with the development of the automobile industry, and have a history of nearly 100 years. The application of road marking paint has generally gone through three development stages: one is the stage of solvent-based cold spray paint; the other is the stage of solvent-free hot-melt paint, which is also widely used at present; the third is the development stage of water-based environmental protection system. At present, the first two coatings still occupy mor...

AI Technical Summary

Problems solved by technology

The existing water-based marking paint generally can only use the scribing method of cold spraying at room temperature, and the thickness can only reach 0.3mm to 0.5mm during construction. It is difficult to ensure the hardness and strength of the coating, and it is impossible to adhere to enough glass reflective beads. If the reflective effect at night cannot be achieved, the service life will be greatly reduced. Generally, it can only last for 3 to 4 months, and the section with heavy traffic will fall off in about 1 month.

In addition, the drying time of water-based marking paint is not ideal. As we all know, construction on the road will inevitably temporarily close the road, and the speed of paint drying will directly affect the passing time of vehicles.
