| Component | Content | Function |
|---|---|---|
| Thermoplastic Resin | 20-25% | Provides adhesion and durability (commonly C5/C9 hydrocarbon or EVA resins). |
| Titanium Dioxide | 10-15% | White or yellow pigment ensures high visibility and UV resistance. |
| Mixed Glass Beads | 20% | Core reflective material (150-850μm) for multi-angle reflectivity. |
| Fillers | 40-45% | Calcium carbonate, quartz sand, etc., reduce costs and enhance wear/slip resistance. |
| Additives | 2-5% | Plasticizers (prevent low-temperature cracking), UV stabilizers (extend lifespan), anti-settling agents (prevent layering). |
20% glass bead content ensures initial retroreflectivity ≥350 mcd·m⁻²·lx⁻¹ (vs. 200-250 for standard products). Pre-mixed + synchronized bead spreading maintains ≥70% reflectivity after 2 years.
Temperature range: -40°C to 80°C (vs. -30°C to 60°C for standard products). 50% better UV resistance for high-altitude, high-UV regions.
Melts at 180-220°C, cures in 3-5 minutes (20% faster than standard products). Low VOC (<5%), compliant with GB 24409-2020 and EPA 1311 standards.
Lane lines, edge lines, arrows (thickness ≥2.5mm, bead spread 600-800g/m²). Handles heavy traffic (>50,000 vehicles/day), lifespan ≥5 years.
Meets ICAO Annex 14 standards for aircraft navigation. Wear resistance ≤30mg (Taber test), resistant to aviation fuel.
40% better wet-night reflectivity, reducing accidents. Tunnel line thickness: 1.8-2.2mm, resistant to vehicle pressure.
Resistant to chemicals (acids, alkalis, oils) for docks, logistics parks. Skid resistance BPN≥75 (vs. 65 for standard products), ensuring safety for special vehicles.
Pavement temperature ≥15°C (vs. ≥10°C for standard products). Air humidity <80% to prevent adhesion issues.
Use dual-bead spreading machines: pre-mix 20% beads, synchronize external bead spreading. Heating kettle temperature error ≤±5°C to avoid resin decomposition.
Pre-mixed beads: 150-300μm (internal) + external beads: 300-850μm (external) for layered reflectivity. Spread beads when paint cools to 110-130°C, ensuring 50-70% embedment depth.
Thickness: Ultrasonic testing, tolerance ±0.2mm. Reflectivity: ≥250 mcd·m⁻²·lx⁻¹ at night (initial value ≥350).
| Feature | 20% Bead Thermoplastic | Standard Thermoplastic | Water-Based Paint |
|---|---|---|---|
| Reflectivity | Very High (350+ mcd) | Medium (200 mcd) | Low (80 mcd) |
| Lifespan | 5-8 years | 3-5 years | 1-2 years |
| Construction Speed | 3-5 minutes curing | 5-8 minutes | 30-60 minutes drying |
| Eco-Friendliness | Low VOC (<5%) | Low VOC (<8%) | Zero VOC |
| Cost | High (￥25-30/kg) | Medium (￥18-22/kg) | Low (￥12-15/kg) |
Store in a cool, dry place away from sunlight (<35°C). Shelf life: 12 months; test fluidity if expired.
Workers must wear heat-resistant gloves and goggles (paint temperature >180°C). Ensure ventilation ≥2000m³/h to prevent harmful gas accumulation.
