“…As a result, the temperature of the sample increased. 29 The crosslink density was found decreased with increasing the temperature of the sample. 23 Therefore, it is possible that the greater number of polysulfidic bonds in the SEV vulcanization systems of the char-filled NR vulcanizates is destroyed when increasing the char loading, resulting in lower crosslink density.…”

Untreated pyrolytic tire char was used in natural rubber (STR20) composites as single filler at loadings of 30–70 phr and co‐filler with carbon black (N330) at a total loading of 50 phr. The results were compared with rubbers filled with N330 and crumb rubber at 30 phr. The effects of fillers on cure characteristic, crosslink density, filler dispersion in natural rubber vulcanizates and their mechanical properties were investigated. The slight reversions were seen for the cure characteristics of 70 phr‐char‐filled and all co‐filler samples because the sulfur amount in the char together with the added sulfur could shift the vulcanization system from EV to SEV, whereas plateau cure curves were seen for the rest. While the highest tensile strength of char‐filled sample was obtained at 50 phr loading, whose tensile strength was about 88% of the N330 sample at 30 phr, 70‐phr‐char filled sample was superior in surface hardness, abrasion resistance and tear strength to N330 sample at 30 phr. For rubber with co‐fillers, the mechanical properties depended on the mass ratio of N330 to pyrolytic tire char. Therefore, it is possible to use untreated char as reinforcing filler for suitable applications according to their properties.

“…1,12 Carbon black/rubber nanocomposites have high strength and good wear resistance. [13][14][15][16] But at the same time, there are defects of large hysteresis loss, large dynamic energy loss, and high rolling resistance, [17][18][19][20] which not only leads to the increase of fuel consumption of the car, but also accelerate the thermal degradation of rubber, shortening the service life of tires and increasing the hidden danger of driving. [21][22][23] Therefore, how to make use of the advantages of carbon black and avoid the disadvantages of carbon black has become an attractive and difficult point in rubber industry research.…”

Carbon black is a very important reinforcing agent for rubber, which can significantly improve rubber modulus, strength, and abrasion performance. However, there are defects such as large hysteresis loss, dynamic energy loss, and high heat build‐up by using carbon black to reinforce rubber. In this paper, a new silane coupling agent named M1 was prepared and introduced as the coupling agent of carbon black, and M1 modified carbon black was prepared. The Fourier transform infrared spectroscopy, thermogravimetric analysis, and X‐ray photoelectron spectrometer results demonstrated the successful modification and revealed the interaction mechanism between M1 and carbon black. The results showed that strong interfacial bonding can be generated between M1 and carbon black through physical and chemical interactions, thereby promoting the dispersion of carbon black in the rubber matrix. Then, carbon black/rubber nanocomposites were prepared with different amount of M1. Because M1 could improve the dispersion of carbon black in the rubber matrix, the carbon black/rubber nanocomposites with M1 have lower network and loss factor, lower rolling resistance, and higher abrasion resistance, which is ideal to manufacture green bus and truck tires for energy‐saving, environment‐friendly, and low‐carbon society.

“…In summary, for the battery pole piece calendering process, people pay more attention to the formula parameters and structural performance of the battery pole piece, while there is little research on the pole piece calendering rubber roller. Regarding the fatigue life and temperature rise of rubber, Simin et al 25 studied the mechanical properties of composite rubber filled with carbon black. It was found that when the loss modulus of lager particle composite rubber was low and carbon black was evenly dispersed, it was more prone to heat dissipation, low temperature rise, and long fatigue life.…”

The calendering process of pole piece is a key step affecting the performance of the power battery. In the calendaring process, rubber roller materials will produce hysteresis heat, resulting in rolling resistance, which will lead to energy loss. The thermo‐mechanical coupling model for calendering rubber roller has been established and the effects of materials, calendering speeds, and roller structure shape on the viscoelastic temperature rise of rubber roller were analyzed. Solution‐polymerized styrene–butadiene rubber (SSBR) materials with different fillers have the greatest impact on temperature rise, followed by the roller shape, and calendering speed is smaller. The loss modulus of SSBR filled with white carbon black studied was smaller, and the temperature rise at high speed was 14.5°C higher than that at low speed. The optimized roller shape has a temperature rise of 10.4°C lower than the original shape. The research results could provide reference for the calendering rubber roller design of pole piece and similar processing.Highlights A thermo‐mechanical coupling model of calendering rubber roller was established. The rubber roller made of SSBR‐VN3 has a lower temperature rise. Optimized structure reduced contact pressure by 28.1% and temperature rise by 10.4°C.
