บทคัดย่อ (EN): A process for production of carbon black/silica/nanoclay ternary filler masterbatch from fresh natural rubber (NR) latex was standardized. The filler, nanoclay at doses varying from 3-10 parts per hundred rubber (phr) along with carbon black and silica at a dose of 25/25 phr was incorporated in fresh NR latex by a modified coagulation process. The coagulum, containing fillers was dried at 70˚C in an air oven to get latex filler masterbatch which was processed further in the conventional way. The master batch compounds containing only silica/carbon black showed higher level of vulcanization as compared to the corresponding dry mixes. The vulcanization level of nanoclay incorporated mixes increased as the content of nanoclay increased. The mechanical properties like tensile strength, modulus, tear strength, abrasion resistance and hardness increased with proportion of nanoclay in the mixes up to 5 phr and with further amount the change was only marginal. The heat build-up values for the tri-filler masterbatches that contained 5 to 10 phr nanoclay was similar to the 25/25 carbon black/silica master batch. Lower tan delta values were observed for all the master batches containing nanoclay in the ranges 3-10 phr compared to the control dry mix containing 25/25 carbon black/silica. Showing better polymer filler interaction. The tan delta values at 60˚C are lower for all the master batches than the dry rubber mix containing 25/25 carbon black/silica. The tri-filler system containing 5 phr nanoclay showed the lowest tan delay at 60˚C and the highest storage modulus and loss modulus within the different ternary filler masterbatches. The improvement in mechanical properties and dynamic properties shown by the silica/carbon black/nanoclay masterbatches over the conventional mill mixed compounds was attributed to factors related to filler dispersion and higher level lf vulcanization. Better filler dispersion was evidenced from the result of filler dispersion data obtained using Dispersion Analyzer and nanoclay exfoliation observed from X-Ray diffractograms.
