AI Technical Summary
Existing SBS modified asphalt has problems such as environmental pollution, high energy consumption, poor storage stability and unstable performance during production and storage, and the investment in on-site production equipment is large and the cost-effectiveness is low.
Cross-linked porous polycarbazole is blended with other components to prepare fast-dissolving, direct-dispensing, high-viscosity asphalt binder through click chemistry. The microporous structure of cross-linked porous polycarbazole is used to adsorb and fix plasticizers and tackifiers, and a heat-conducting network is used to improve heat transfer efficiency, thereby achieving rapid melting and uniform dispersion.
It enables the rapid and uniform dispersion of high-viscosity asphalt binder under conventional mixing conditions, reducing energy consumption and environmental pollution, improving storage stability and performance consistency, and avoiding reliance on high-shear equipment.
