Silica dispersibility and mechanical properties of silica/SBR compound by using carboxylized acrylic monomer-based low molecular weight copolymer |
| 초록 |
Wet masterbatch (WMB) is a technique for producing rubber compounds by using water as a solvent to coagulate surface-modified silica. This technique is a process for producing a high content of silica filler and a rubber compound with improved silica dispersibility. However, WMB technology has difficulties in improving the mechanical properties of the rubber compound due to the low silica dispersibility due to the silica aggregation when the silica content is higher than 100 phr. In this study, an amphiphilic silica dispersant was applied to the WMB process. The amphipathic silica dispersant was synthesized by copolymerizing carboxylated acrylic monomer and acrylamide. The improvement of silica dispersibility in the rubber compound with dispersant was measured by Rubber Process Analyzer. In addition, both the wear resistance measured by DIN abrasion and the dynamic viscoelastic property measured by Dynamic Mechanical Analyzer were enhanced when the content of dispersant was 6 phr. |
