The present work investigates the properties of natural rubber (NR) filled with different contents of reinforcing carbon black (CB) and other compounding ingredients. The curing characteristics were tested at 157°C. It was found that the equilibrium solvent uptake ( Qmax) decreases with the increase of the CB concentration due to reduction of the free volume. Mechanical properties such as tensile strength and hardness of CB filled rubber composites were remarkably improved, indicating the inherent reinforcing potential of CB. The percentage of elongation at break of filled CB rubber was found to be lower than that of pure NR. The dielectric constants ( ε′), dielectric loss ( ε″), and alternating current (AC) electrical conductivity ( σAC) were investigated for all samples as a function of frequency and temperature. It is concluded that the high CB content causes the formation of channels, increasing the AC conductivity of the composites.

Studies show that the dispersion of silica in the mixing process is an important factor affecting the wear of the mixing chamber. As the most important mixing equipment, the long operational life of the internal mixer will cause wear in the rotor and chamber of the internal mixer. This wear increases the gap between the rotor and chamber of the internal mixer, reduces the mixing performance, weakens the dispersion of packing, and adversely affects the quality of the rubber produced. Therefore, it is important to investigate the metal wear in the mixing process. This article examines the effect of the addition of different amounts of silane coupling agents on metal friction and wear during the mixing process. The silane coupling agent has two functions. The first is to make the surface of the silica hydrophobic, enabling it to combine the inorganic matrix of the silica with the organic matrix of the rubber; the second is to inhibit the aggregation of the silica in the rubber. In the present study, we examine (1) the influence of different formulations on the friction and wear of the metal in the mixing chamber from the perspective of formulation technology, and (2) the correlation between corrosion wear and abrasive wear. It is found that a rubber compound with 6 phr of TESPT has the lowest metal wear and that adding more TESPT does not affect the degree of metal wear. As the amount of TESPT increases, the proportion of abrasive wear decreases, while the proportion of corrosive wear increases, reaching a maximum of 20.7%. In our study we found that abrasive wear is the predominant wear mechanism of a rubber compound on metal. In contrast, the corrosive wear caused by high-temperature water vapor still occupies a large proportion of the total wear. Therefore, improving silica dispersion and reducing abrasive wear are extremely important methods to protect the mixing chamber. However, the corrosion of metals by high-temperature water vapor should also be considered when preparing for the mixing process.

Pyrolysis carbon black is the pyrolysis product of waste tires. The high‐value utilization of pyrolysis carbon black can reduce black pollution of the environment, achieve sustainable development, and solve the problem of energy supply and consumption in the world. This paper mainly studies the modification and excitation of low‐temperature plasma on pyrolysis carbon black. It proposes a micro flocculation wet process (DMLI process) for preparing master rubber by wet mixing. Combined with DMLI process, the vulcanization performance, physical and mechanical properties, Payne effect, and dynamic mechanical properties were also analyzed and characterized. The results showed that the properties of the rubber compound prepared by low‐temperature plasma modification of pyrolytic carbon black were significantly improved. The modified pyrolytic carbon black had the characteristics of less ash, higher activity, and stronger affinity with rubber, and the wettability was significantly improved. In wet mixing, the new DMLI process can effectively improve the degree of combination and dispersion of carbon black and natural rubber latex. Therefore, the modified pyrolytic carbon black can completely replace the industrial carbon black N330, thereby preparing high‐performance rubber composites, realizing the high‐value utilization of pyrolytic carbon black and sustainable green development.
