Silica dispersibility and its correlationship with properties of silica/SBR compounds using cellulose dispersant |
| 초록 |
In silica-SBR rubber compound at tire tread, silica has a hydrophilic group and does not mix well with the rubber, resulting in some agglomeration phenomena. The mechanical properties, and wear resistance of the rubber compound are related to the silica dispersibility. To improve silica dispersibility, the wet masterbatch (WMB) process was introduced and there is also increasing interest in silica dispersants. We evaluated an eco-friendly cellulose as a dispersant of the rubber compound in the WMB process. The vulcanization properties and processability of silica/SBR compounds using cellulose dispersant were compared using a Moving Die Rheometer and Mooney Viscometer, respectively. The DIN abrasion of silica/SBR compounds with cellulose dispersant improved by up to 29%. |
