Abstract

To mitigate the issues of high energy consumption and extended processing times commonly associated with rubber compounding, this study explores the vulcanization characteristics and physico-mechanical properties of rubber composites prepared using the wet mixing method with three different particle sizes of carbon black. Comparative analysis with the conventional dry mixing approach reveals distinct advantages of the wet method depending on the type of carbon black used. For N110, the sieving filtration wet process yields the most favorable overall performance. For N234, both the grinding and sieving filtration wet mixing techniques significantly enhance material properties relative to dry mixing, with negligible differences observed between the two wet methods. For N326, the grinding wet process offers superior comprehensive performance. Additionally, powdered carbon black demonstrates rapid dispersibility in natural latex under wet mixing conditions, which not only shortens processing time but also contributes to improved filler dispersion and overall rubber performance, while realizing the green and low-energy processing of rubber.


Keywords: wet mixing, natural latex, powdered carbon black, pretreatment.
