AI Technical Summary
In existing technologies, styrene-butadiene latex has unsatisfactory low-temperature performance and limited improvement in high-temperature performance in asphalt modification. Furthermore, the softening point and adhesion to aggregates of the modified asphalt are insufficient, leading to problems such as particle loss and rutting.
Using isoprene and styrene as the main monomers, combined with SBS and SIS block copolymers, and through the regulation of components such as cationic emulsifiers and pre-crosslinking agents, a high-solids-content polymer emulsion is prepared. A low-temperature polymerization process and agglomeration technology are then used to form modified asphalt with crosslinking points.
It significantly improves the high and low temperature performance of asphalt, enhances the softening point and adhesion of modified asphalt to aggregates, solves the problem of unsatisfactory low temperature performance, and reduces the energy consumption of subsequent dehydration and solvent removal.
