Effect of acrylic acid-based copolymer on silica-SBR compounds to improve workability and wear resistance |
| 초록 |
The silica dispersibility of silica-SBR compounds is related to the wear resistance, wet traction, and fuel efficiency characteristics of tires. Recently, in order to improve the silica dispersibility of the silica-SBR compound, studies have been carried by introducing the wet masterbatch (WMB) process which is a method of mixing rubber in water phase. We expected to improve the silica dispersibility of the silica-SBR compounds by preparing a silica dispersant applicable to the WMB process. For this purpose, acrylic acid (AA) and acrylamide (AAM) were copolymerized to prepare a poly(AA-co-AAM), which was then introduced into the WMB process as a silica dispersant. The silica dispersibility of the compounds was confirmed by moving die rheometer and dynamic mechanical analyzer. The workability improvement of silica-SBR compounds was measured by mooney viscosity (MV) meter. The wear resistance of silica-SBR compound using dispersant was improved by up to 25%. |
