摘要：
In order to study the effect of particle size distribution of carbon black（CB）on natural rubber, for the first time, the fineness modulus MXCB of carbon black particle size distribution was introduced, established the ideal model of carbon black particle, calculated the ideal surface area coefficient S of carbon black particles, and combined with the practical production and application experience, the theoretical optimal particle size distribution of carbon black which can meet both the primary and secondary dispersion was calculated. At the same time, N550 (carbon black,soft) and N234 (carbon black,hard) were selected for the particle size distribution adjustment experiment to study the dispersity, physical mechanical and dynamic properties of natural rubber filled with them. The experimental results show that N550 and N234 with the optimal particle distribution have better carbon black dispersion than other samples, and the processing, mechanical and wear resistance properties of the rubber are improved to a certain extent.No matter soft or hard carbon black, the performance of carbon black with optimal particle distribution presents a positive trend, which proves that different particle sizes of carbon black have a dynamic balance in reinforcing dispersion performance of rubber compound. In the future, particle distribution design can be carried out according to different product requirements with further research, and the particle distribution can also be monitored by using equilibrium factor MXcarbon · S in carbon black production. © 2023 Chengdu University of Science and Technology.
