Now many asphalt producers will look for carbon black manufacturers to use in asphalt. In fact, for those who don’t know, they don’t know that carbon black can be used in asphalt. This article will introduce the effect of modified carbon black on the performance of asphalt. Influence, the role of pitch plus carbon black and other information related to carbon black for pitch.
The role of pitch plus carbon black
1. Disperse a small amount of carbon black into asphalt, and the viscoelastic properties, wear resistance and mechanical strength of asphalt will be improved.
2. Adding 15 parts of carbon black to asphalt can extend the life of the pavement from 6 to 9 years to 10 to 15 years.
3. Adding carbon black to asphalt is similar to the reinforcing phenomenon of carbon black in rubber and plastics.
4. Compared with the general asphalt road, the asphalt pavement added with carbon black can inhibit the decrease of the hardness of the pavement when the temperature rises, prevent ultraviolet aging, and improve the crack resistance, fatigue resistance (increased rigidity) and wear resistance.
Pitch carbon black blending ratio
Dispersing submicron carbon black in road asphalt at a dosage of 11-16% of the asphalt weight can significantly improve the durability, wear resistance and temperature-viscosity characteristics of asphalt. That is to say, the blending ratio of pitch carbon black is between 11:100 and 16:100.
Application of carbon black for asphalt
Carbon black for asphalt In addition to road asphalt, the carbon black is also used in asphalt protective films for buildings, asphalt adhesives, asphalt sealants and asphalt paints.
Can cracking carbon black be used in modified asphalt?
Cracking carbon black can be added to modified asphalt. Using cracking carbon black to modify asphalt can not only improve the performance of asphalt mixture in some aspects, but also reduce costs and improve the recycling rate of waste rubber, which has good economic benefits. with environmental benefits.
