Water-based acrylic road marking paint: the invisible guardian of road safety

In the modern transportation system, clear and eye-catching road markings are important infrastructure to ensure traffic safety. Whether it is the hustle and bustle of the city or the traffic in the countryside, road markings are like silent guides, guiding vehicles and pedestrians to pass in an orderly manner. Among the many road marking materials, water-based acrylic road marking paint has gradually become a "star product" in the field of road marking with its unique performance and environmental advantages.

1. The core advantages of water-based acrylic road marking paint

Excellent environmental performance

Traditional solvent-based marking paint releases a large amount of volatile organic compounds (VOCs) during production and use. These substances not only threaten the health of construction workers, but also aggravate air pollution, form photochemical smog, and harm the ecological environment. Water-based acrylic marking paint uses water as a solvent, contains almost no organic solvents, and has extremely low VOCs emissions. It meets the requirements of national environmental protection policies and is a typical representative of green and environmentally friendly coatings. During the construction process, there is no pungent odor, which can effectively improve the construction environment and reduce the impact on surrounding residents and ecology.​

Excellent physical properties​

Water-based acrylic marking paint has good wear resistance and weather resistance. Road markings are exposed to the outdoors for a long time, and are subjected to frequent vehicle rolling, sun and rain, wind and snow erosion, etc. Ordinary paints are prone to wear and fading. With its special formula and molecular structure, water-based acrylic marking paint can form a tough paint film on the road surface. Even on roads with heavy traffic, it can remain clear and complete for a long time, greatly reducing the maintenance frequency and cost of road markings. In addition, the marking paint also has excellent adhesion and can firmly adhere to a variety of road substrates such as cement and asphalt, and is not easy to peel off. ​

Fast drying speed​

In road construction, time is efficiency. The fast drying speed of water-based acrylic marking paint gives it a significant advantage in practical applications. Under normal circumstances, it can be dry on the surface 10-30 minutes after construction at room temperature, and it can be completely dry in 1-2 hours, which greatly shortens the construction time and reduces the impact of road closures on traffic. It is particularly suitable for places such as urban roads and airport runways that have strict requirements on construction time.​

2. Wide application areas​

Road traffic markings​

On urban roads, highways, national and provincial roads and other types of roads, water-based acrylic marking paint is an ideal material for marking traffic lines. It can clearly mark lane demarcation lines, edge lines, guide arrows, pedestrian crossing lines, etc., provide clear traffic guidance for drivers and pedestrians, regulate traffic order, and reduce the occurrence of traffic accidents. At the same time, its good reflective performance can make the markings clearly visible at night or in low light conditions, further ensuring driving safety. ​

Parking lot and garage markings​

Parking lots and garages are concentrated areas for vehicle parking. The clarity of the markings directly affects the parking efficiency and safety of vehicles. Water-based acrylic marking paint can be used to divide parking spaces, lane lines, entrance and exit indicator lines, etc., which can not only make the parking lot layout more reasonable and orderly, but also guide vehicles to park accurately through eye-catching colors and clear lines to avoid scratch accidents. In addition, its environmental protection characteristics also meet the use requirements of relatively closed spaces such as parking lots and garages.​

Sports field marking lines

In various sports venues, such as basketball courts, tennis courts, football fields, etc., water-based acrylic marking paint is used to divide the boundaries of the venue, regional markings, etc. It has the characteristics of bright colors and long-lasting non-fading, which can provide athletes with clear venue boundaries and ensure the fairness and standardization of the competition. At the same time, good wear resistance and anti-slip properties can meet the needs of athletes in high-intensity sports and reduce the risk of sports injuries. ​

Other fields

In addition to the above main application scenarios, water-based acrylic marking paint can also be used for factory workshop floor markings, school playground markings, commercial area sidewalk markings and other fields, providing clear and durable marking services for different places. ​

3. Scientific construction methods

Preparation before construction

Before construction, the road surface needs to be thoroughly cleaned to ensure that the road surface is dry, clean, free of oil, dust and other impurities. Loose particles and attachments on the road surface can be removed by sweeping with a broom, washing with a high-pressure water gun or mechanical grinding. At the same time, check the flatness and roughness of the road surface. For uneven roads, repairs should be carried out to ensure the quality of the marking. In addition, it is necessary to prepare the equipment required for construction, such as marking machines, paint mixers, spray guns, etc., and debug the equipment to normal working conditions. ​

Preparation of paint​

According to the requirements of the product manual, mix the water-based acrylic marking paint with an appropriate amount of water and stir evenly. The amount of water added during the preparation process must be strictly controlled. Too much or too little will affect the performance and construction effect of the paint. At the same time, according to actual construction needs, an appropriate amount of reflective glass beads can be added to improve the reflective performance of the marking. When adding glass beads, they should be added evenly during the mixing process of the paint to ensure uniform dispersion. ​

Construction process​

When using a marking machine for construction, the parameters of the marking machine, such as nozzle size, paint flow, driving speed, etc., should be adjusted according to the width and shape of the marking line. During the construction process, the marking machine should be kept at a constant speed to avoid speed fluctuations or pauses in the middle to ensure uniform thickness and straight lines. For some complex marking patterns or irregular areas, a spray gun can be used for manual re-marking to ensure the integrity and accuracy of the markings. After the construction is completed, the construction equipment should be cleaned in time to avoid the paint from drying and clogging the equipment. ​

Maintenance after construction​

After the construction is completed, before the markings are completely dry and solidified, warning signs should be set up to prohibit vehicles and pedestrians from passing through to avoid damage to the markings. At the same time, pay attention to weather changes to avoid being affected by bad weather such as rain and sun exposure in a short period of time after construction. Generally, it takes about 24 hours for the markings to completely dry and solidify. During this period, the protection and inspection of the markings should be strengthened, and problems should be dealt with in a timely manner. ​

4. Future development trends​

With the continuous improvement of people's environmental awareness and the increasingly stringent national environmental protection policies, the market demand for water-based acrylic marking paint will continue to grow. In the future, this product will develop in the direction of high performance and multi-functionality. For example, by improving the formula and production process, the wear resistance, water resistance, chemical corrosion resistance and other properties of the coating can be further improved; new water-based acrylic marking paints with self-repairing, self-cleaning, anti-skid and noise reduction functions can be developed to meet the special needs of different scenarios. At the same time, with the continuous development of intelligent construction equipment, the construction efficiency and quality of water-based acrylic marking paints will also be further improved, promoting the road marking industry to move towards a more intelligent and automated direction. ​

Water-based acrylic road marking paints play an increasingly important role in the field of road markings due to their environmental protection, excellent performance, and wide application. Whether it is to ensure traffic safety or to enhance the image of the city, it has made an indelible contribution. I believe that in the future, with the continuous advancement and innovation of technology, water-based acrylic marking paints will bring more convenience and safety to our lives.
