“…What's more, the T 50 and T max of B30M10, B50M10, and B30M30 are all higher than those of B30M0. Apparently, as a compatilizer, MPTMS attributes to the exfoliation and good dispersion of bentonite, delaying the decomposition of rubber [43]. Interestingly, the control sample with no catalyst during the synthesis also shows higher T 50 and T max than most of the other samples though its mechanical strength is very poor.…”

Acrylonitrile butadiene rubber (NBR)/bentonite (Bt) nanocomposites were synthesized by an one-step method in NBR latex with (3-Mercaptopropyl)trimethoxysilane (MPTMS) as a compatilizer. The nanocomposites were compounded with curing additives and then vulcanized. The prepared vulcanizates were characterized by Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). The curing properties and mechanical properties were also investigated. The thermal properties were studied with thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC). The morphology was investigated by field emission-scanning electron microscopy (FE-SEM). By swelling test, the swelling ratio and the crosslinking density were achieved. The hydrolyzation and condensation of MPTMS was identified by FTIR while the intercalated/exfoliated structure of Bt was determined by XRD. It was evident that the mechanical properties of the nanocomposites were significantly improved compared with the neat NBR. The welldispersed bentonite particles and effects of MPTMS were supported by the images from FE-SEM. The results of TGA showed that the fastest weight-loss temperature (T max ) was elevated by over 10

“…35 To correlate the macromechanical properties with the microstructure of the prepared NR/SBR/OC nanocomposites, tensile properties of the prepared vulcanized nanocomposites were evaluated as demonstrated in Figures 12(a,b) and 13. It is clearly seen that both compatibilized nanocomposites originated from ENR50 and EPDM-g-MAH as compatibilizer exhibited enhanced strength as well as stress at 100 and 300% elongation in comparison with the neat and uncompatibilized filled NR/SBR vulcanizates.…”

Nanocomposites based on (70/30) blends of natural rubber (NR), styrene-butadiene rubber (SBR), and organoclay (OC) have been prepared successfully via meltmixing process. Effects of the extent of polymers/clay interactions upon the developed microstructure, fatigue life, and dynamic energy loss by the nanocomposites have been investigated. Maleated EPDM (EPDM-g-MAH) and epoxidized NR (ENR50) were employed as compatibilizer. Nanocomposites were characterized by means of X-ray diffractometer (XRD), transmission electron microscope (TEM), scanning electron microscope, atomic force microscopy, root mean square, and dynamic mechanical thermal analysis. EPDM-g-MAH showed more potential in enhancing dispersion of the clay nanolayers and their interaction with rubber phases. More potential for separating and dis-persing the clay nanoplatelets with better interface enhancement was exhibited by EPDM-g-MAH as compatibilizer. This was consistent with higher resistance towards large strain cyclic deformations along with more heat build-up characteristics showed by EPDM-g-MAH based nanocomposites especially at compatibilizer/organoclay ratio of 3. Pronounced non-terminal behavior within low frequency region was also observed for melt storage modulus of this nanocomposite, indicating higher extent of intercalation/ exfoliation microstructure with reinforced interfaces than the nanocomposite generated by ENR50.

“…This was because the short chain of C5, which combined with the macromolecule segment, reduced the degree of freedom of rubber, improved the temperature of transforming to vitrification, and increased the crosslinking between the rubbers. 13 When the dosage of C5 was no more than 15 phr, the influence on the DIN abrasion of the material was low. Table 2 demonstrates that the tensile strength of the material increased firstly and then decreased, and the elongation at break improved constantly with the increase in C5 dosage.…”

With the development of industrialization, rubber has been gradually used in the manufacture of sports equipment for its favourable properties. This study involved the addition of C5 petroleum resin into brominated isobutylene-isoprene rubber (BIIR) and butadiene rubber (BR) while manufacturing the sole of running shoes. The effects of running shoes with abrasion resistant rubber sole on the exercise capacity of the human body were investigated by analysing the skid resistance and abrasion resistance of the running shoes, and conducting biomechanical study on naked feet and feet wearing the shoes. The results demonstrated that the rubber sole had favourable slip resistance property and mechanical properties such as stretching, abrasion resistance, and hardness. Compared to naked feet, the peak pressure intensity of the whole step of feet wearing the newly developed shoes, was significantly lower than that of feet wearing ordinary shoes. In the future, rubber can bring more comfortable experience because of its favourable properties.
