Effect of reynolds number on the dispersion of carbon black in natural rubber latex and filler-rubber interfacial interaction in high-speed jet flow field

Abstract

A novel strategy of high‐speed impinging jet processing technique was developed to prepare rubber composites by directly mixing natural rubber latex (NRL) with carbon black (CB). The results showed that CB could be more evenly dispersed into natural rubber by jet compounding technique, compared with the traditional dry process. The dispersion of carbon black was improved at higher Reynolds number because of more intensive shear force. Furthermore, a high performance of natural rubber latex/CB composite was gained by jet compounding technique. When compared to the traditional dry process, the mechanical properties and abrasion resistance of the composite prepared by the jet compounding technique were greatly improved because of the improved filler–rubber interaction at higher Reynolds number.

High‐performance natural rubber latex composites developed by a green approach using ionic liquid‐modified multiwalled carbon nanotubes

“…The dispersion and distribution of MWCNTs, the interaction between MWCNTs and ILs, as well as rubber fatigue resistance are the main focus of the work. Compared with conventionally produced rubber composites, those obtained by the liquid latex blending method, have improved properties, and are more eco‐friendly due to the assistance of the IL.…”

Preparation of Water-suspensible Carbon Nanoparticles and Their Influence on the Properties of Epoxidized Natural Rubber Latex

“…To date, there have been a number of methods developed to disperse CBs into water and latex. Many researchers used advanced processes and equipments to get better dispersion [7][8][9][10]. However, it ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT 4 was found that there was only a slight decrease of the particle size of the CBs and little improvement of its dispersion in water [6].…”
