Road marking paint plays a vital role in traffic safety. Its main functions are to guide traffic, regulate vehicle and pedestrian behavior, and improve road visibility and aesthetics. Choosing the right type of paint can not only ensure the durability and clarity of the marking, but also reduce maintenance costs and improve traffic safety.
This article will introduce the main types of road marking paints, their respective characteristics and their scope of application in detail.
What are the types of road marking paints?
1. Solvent-Based Paints:
Solvent-Based Paints are one of the traditional types of road marking paints. Its main ingredients include pigments, resins and organic solvents. This type of paint dries quickly, has strong adhesion, and is suitable for all weather conditions.
● Advantages of Solvent-Based Paints:
● Fast drying: Solvent-Based paints have a short drying time, usually within a few minutes to half an hour, which reduces the road closure time.
● Strong adhesion: This paint has good adhesion and is suitable for various road surfaces such as asphalt and concrete.
● Good wear resistance: Solvent-based road marking paint has strong wear resistance and is suitable for roads with high traffic volume.
● Disadvantages of solvent-based road marking paint:
● Environmental issues: The organic solvents in solvent-based road marking paint will produce volatile organic compounds (VOCs) after evaporation, which has a certain impact on the environment and health.
● Strong odor: A strong odor will be generated during the construction process, which may cause discomfort to construction workers and surrounding residents.
2. Water-based road marking paint (Water-Based Paints):
Water-based road marking paint uses water as a solvent and has good environmental performance. It is a type of road marking paint that has been widely promoted in recent years.
● Advantages of water-based road marking paint:
● Environmental protection: Water-based road marking paint does not contain organic solvents, has low VOCs emissions, and has little impact on the environment and health.
● Small odor: The odor is small during construction, which is more friendly to construction workers and the surrounding environment.
● Easy to clean: Construction tools and equipment are easy to clean and do not require the use of solvents.
● Disadvantages of water-based road marking paint:
● Long drying time: Compared with solvent-based road marking paint, water-based road marking paint takes longer to dry, usually 30 minutes to 1 hour, and may require longer road closure time.
● Poor weather resistance: In high or low temperature environments, the performance of water-based road marking paint may not be as stable as solvent-based road marking paint.
3. Thermoplastic Paints:
Thermoplastic road marking paint is a road marking paint that is applied to the road surface after heating and melting. It dries very quickly and has a long service life.
● Advantages of Thermoplastic Road Marking Paint:
● Quick drying: Thermoplastic road marking paint can be cooled and solidified within a few minutes after application, greatly reducing the road closure time.
● Strong durability: This paint has extremely high wear and weather resistance, with a service life of up to 3 to 5 years, suitable for roads with high traffic volume.
● Good reflective performance: Glass beads are usually added to thermoplastic road marking paint to enhance the reflective performance of the marking and improve visibility at night and in bad weather conditions.
● Disadvantages of Thermoplastic Road Marking Paint:
● Complex construction: The construction of thermoplastic road marking paint requires professional equipment and technology, and the construction cost is relatively high.
● Environmental issues: Although thermoplastic road marking paint has good environmental performance after curing, it will produce certain smoke and odor during the construction process.
4. Two-Component Road Marking Paint:
Two-Component Road Marking Paint consists of two chemical components, which need to be mixed before construction and have excellent wear resistance and weather resistance.
● Advantages of Two-Component Road Marking Paint:
● Strong durability: Two-component road marking paint forms a hard coating after drying, which has extremely high wear resistance and weather resistance and a long service life.
● Strong adhesion: This paint has good adhesion to various road surfaces such as asphalt and concrete.
● Quick drying: It dries quickly after mixing, reducing the road closure time.
● Disadvantages of Two-Component Road Marking Paint:
● Complex construction: Two-component road marking paint requires precise mixing ratios and professional construction technology, and the construction is difficult.
● High cost: Due to the complexity of construction and material costs, the total cost of two-component road marking paint is high.
How to choose the road marking paint that suits you?
Choosing the road marking paint that suits you needs to consider the road surface type, traffic volume, climate conditions, construction conditions, etc.
1. Road surface type
Different types of roads have different requirements for road marking paint. For example:
● Asphalt road surface: Suitable for solvent-based road marking paint or hot melt road marking paint with strong adhesion.
● Concrete road surface: Suitable for two-component road marking paint or water-based road marking paint with good wear resistance.
2. Traffic volume
Roads with heavy traffic need to choose road marking paint with strong wear resistance and weather resistance, such as hot melt road marking paint or two-component road marking paint.
3. Climate conditions
Climate conditions have an important influence on the choice of road marking paint. For example:
● High temperature environment: Suitable for solvent-based road marking paint or hot melt road marking paint with good high temperature resistance.
● Low temperature environment: Suitable for water-based road marking paint or two-component road marking paint with good low temperature drying performance.
4. Construction conditions
Construction conditions include construction time, construction equipment and personnel technical level. For example:
● Short-time construction: Suitable for using hot-melt marking paint or solvent-based marking paint that dries quickly.
● High environmental protection requirements: Suitable for using water-based marking paint with good environmental performance.
Application cases of road marking paint
1. Urban roads:
Urban roads have a large traffic volume, and high requirements are placed on the wear resistance and reflective performance of the marking paint. Common types of marking paints include hot-melt marking paint and two-component marking paint. These paints have high wear resistance and reflective performance, and can effectively improve road visibility at night and in bad weather conditions.
2. Expressways:
Highways have high speeds and large traffic volumes, requiring marking paints to have excellent wear resistance and weather resistance. Two-component marking paints and hot-melt marking paints are common choices. These paints are not only highly wear-resistant, but also have good reflective performance, which can significantly improve driving safety on expressways.
3. Parking lots:
The marking paint in parking lots is mainly used to divide parking spaces and guide traffic directions, and has certain requirements for wear resistance and environmental protection performance. Water-based road marking paint is a common choice. It has good environmental performance and low odor, and is suitable for use in indoor and underground parking lots.
Environmental and safety considerations
When selecting and using road marking paint, its impact on the environment and safety must be considered. Environmentally friendly marking paints such as water-based marking paints and low-VOCs solvent-based marking paints can reduce pollution to the environment and protect the health of construction workers and surrounding residents. At the same time, necessary safety measures should be taken during the construction process to ensure the safety of construction workers.
