炭黑母炼胶的湿法制备工艺及性能研究

he carbon black masterbatch was prepared with NR latex as raw material ,blending CB slurry through colloid mill dispersion,after screening, washing, dehydrating, drying. We study the dispersion of N330 and the mechanical property of carbon black vulcanized masterbatch (WET-CMB).The result shows that，the dispersion of carbon black N330, using colloid mill, concentrated grain size distribution, particle uniformity. By SEM analysis, its basically no hole on vulcanized rubber's tensile section, carbon black dispersion is uniform. Compared with traditional dry vulcanized masterbatch（DRY-CMB）, mechanical properties has little difference, ageing resistance was good. When carbon black filled quantity was 60phr, the abrasion index reached maximum, significantly improved wear resistance.
