Epoxy PE wax powder modifies asphalt, and wax has an impact on the three major indicators of asphalt. The asphalt with high wax content and the same grade with low wax content Asphalt, the softening point increases, the ductility decreases, the penetration increases, the water damage resistance of the asphalt mixture becomes poor, the adhesion to the aggregate becomes poor, it is easy to peel off, and high temperature is prone to rutting.
Similarly, at low temperature, the asphalt will become brittle and hard, resulting in a decrease in the low-temperature crack resistance of the pavement and cracks. In addition, wax will make the asphalt and stone stick Adhesion is reduced. Under the condition of water, pavement stones will peel off, causing pavement damage. More seriously, waxy asphalt will reduce the skid resistance of asphalt pavement and affect the driving safety of pavement.
The wax content of asphalt is the content of wax crystallized in a specified solvent and low temperature after the oil is distilled off by distillation.
Impact on asphalt pavement:
1. It becomes soft at high temperature. Therefore, the asphalt mixture mixed with asphalt with high wax content is also easy to become soft and has poor high temperature stability.
2. It becomes hard and brittle at low temperature, and its deformation ability is poor under low temperature conditions. Therefore, the asphalt mixture pavement has poor low temperature deformation ability.
3. Due to the presence of wax, it is easy to peel off asphalt and aggregate (that is, reduce adhesion).
4. Wax is easy to wrap on the stone surface, which reduces the skid resistance of asphalt pavement.
5. The presence of wax will lead to inaccurate laboratory test data, thus affecting the quality of asphalt mixture pavement.
Product characteristics of polyethylene wax for epoxy PE wax powder:
1. High melting point: high softening point, which can improve the heat resistance of the coating;
5. High strength: toughness, which can effectively improve the strength of road markings;
6. Good wettability: it can wet titanium dioxide well, give full play to the covering ability of titanium dioxide, and increase the whiteness of marking paint;
Use scenarios: high-end and mid-range hot-melt road marking paint, hot-melt protrusion marking paint, hot-melt colored non-slip road surface, etc.
