White marking paint is one of the indispensable materials in road traffic management. It is mainly used to draw road markings to help guide traffic and ensure driving safety and order.
This article will discuss the definition, function, types and characteristics of white marking paint in detail to help readers fully understand this key road paint.
What is white marking paint? What are its types?
White marking paint is a paint specially used for marking on road surfaces. It has high reflectivity, wear resistance and skid resistance. It is clearly visible during the day and at night, ensuring that road markings can effectively guide traffic in all weather conditions.
What is the role of white marking paint?
The main functions of white marking paint include: traffic guidance, road separation, and warning.
1. Traffic guidance: guide vehicles and pedestrians through clear markings and regulate road use behavior.
2. Road separation: used to divide lanes, driving lanes, parking spaces, etc. to ensure that vehicles drive in an orderly manner.
3. Warning function: remind drivers to slow down or pay attention to dangerous sections by setting warning markings to improve driving safety.
What are the types of white marking paint?
According to the use environment, material composition and construction method, white road marking paint can be divided into many types, mainly including hot melt road marking paint, solvent-based road marking paint, water-based road marking paint and preformed road marking tape.
1. Hot melt road marking paint
Features of hot melt road marking paint:
Hot melt road marking paint is a road marking paint that needs to be heated and melted before being applied on the road. It has the characteristics of fast drying, wear resistance and strong adhesion, and is suitable for roads with high traffic volume.
Construction process of hot melt road marking paint:
Hot melt road marking paint requires the use of professional heating equipment to heat the paint to 180℃-200℃, and then it is evenly applied on the road surface through special equipment. After cooling, the coating hardens rapidly to form a solid marking line.
Advantages and disadvantages of hot melt road marking paint:
● Advantages: strong durability, good wear resistance, fast construction speed, suitable for large-area construction.
● Disadvantages: complex construction equipment, high temperature heating is required, and high requirements for the construction environment are required.
2. Solvent-based road marking paint
Characteristics of solvent-based road marking paint:
Solvent-based road marking paint is composed of synthetic resin, pigment, filler and organic solvent, and has good adhesion and durability. After coating, the solvent evaporates and the coating solidifies.
Construction process of solvent-based road marking paint:
The construction of solvent-based road marking paint is relatively simple, and it can be applied with a brush, roller or spray equipment. The coating dries quickly and can generally be completely cured within a few hours.
Advantages and disadvantages of solvent-based road marking paint:
● Advantages: convenient construction, low equipment requirements, suitable for small areas and complex markings.
● Disadvantages: The durability is not as good as hot melt type, and the volatilization of solvent may have an impact on the environment.
3. Water-based road marking paint
Characteristics of water-based road marking paint:
Water-based road marking paint uses water as a solvent, is environmentally friendly, and is suitable for areas with high environmental requirements. It has good adhesion and durability, and a moderate drying speed.
Construction process of water-based road marking paint:
Water-based road marking paint can be applied using spray equipment or brushes, and the construction process is simple. Since water is used as a solvent, it dries quickly and can usually be cured within a few hours.
Advantages and disadvantages of water-based road marking paint:
● Advantages: environmentally friendly, no solvent volatile pollution, and easy construction.
● Disadvantages: The durability is slightly inferior to hot-melt road marking paint, and it is not suitable for roads with high traffic volume.
4. Preformed marking tape
Features of preformed marking tape:
Preformed marking tape is a pre-made marking material that can be directly pasted on the road surface. It has the characteristics of high reflectivity, wear resistance and easy construction.
Construction process of preformed marking tape:
Preformed marking tape is easy to construct, just paste it on the road surface and compact it. No heating or solvent is required, suitable for quick construction and temporary marking.
Advantages and disadvantages of preformed marking tape:
● Advantages: quick construction, good reflective effect, suitable for temporary marking and quick repair.
● Disadvantages: high cost, slightly inferior durability to hot-melt road marking paint.
Application scenarios of different types of white road marking paint
1. Expressway: Highway traffic volume is large and speed is fast, and the durability and clarity of the markings are high. Hot-melt road marking paint has become the first choice for highway markings due to its excellent wear resistance and quick drying characteristics.
2. Urban roads: Urban roads have dense traffic and complex traffic conditions. Solvent-based road marking paint and water-based road marking paint are widely used in the drawing of urban road markings due to their convenient construction and good environmental protection.
3. Temporary road marking: Temporary road markings need to be set up and removed quickly on construction sections or activity venues. Preformed road marking tapes are an ideal choice for temporary road markings due to their quick construction and good reflective effect.
4. Parking lot: Parking lot markings require good wear resistance and high clarity. Both hot-melt road marking paint and solvent-based road marking paint are suitable for the drawing of parking lot markings. The specific choice depends on the construction conditions and budget.
Construction and maintenance of road marking paint
1. Preparation before construction:
Before construction, the road surface needs to be cleaned and treated to ensure that there is no oil, dust and loose particles. According to different types of road marking paint, choose appropriate construction equipment and tools.
2. Construction process:
● Hot melt road marking paint: Use heating equipment to heat the paint to the specified temperature, and evenly apply it on the road through special equipment. After cooling, it forms a marking line.
● Solvent-based road marking paint: Use a brush, roller or spray equipment to apply, and the coating will solidify after the solvent evaporates.
● Water-based road marking paint: Use spray equipment or brush to apply, and the coating will solidify after the water evaporates.
● Preformed road marking tape: Directly stick it on the road surface and compact it.
3. Maintenance and repair：
Road markings will be affected by wear and aging as they are used for a longer time. Regularly check the clarity and integrity of the markings, and repair and redraw them when necessary to ensure that the markings always effectively guide traffic.
