“…In addition, according to SEM, the original DT had a larger powder size, and the particles were aggregated together. However, after modification, the particle size of DT was significantly smaller, and this was attributed to removing of impurities together with coating of the modifier which may reduce the agglomeration of DT [30].…”

“…In addition, some researchers investigated the application properties of modified DT in rubber composites. Wu et al [30] used modified diatomite to reinforce different types of rubbers by ultrasonic dispersion technology. Through detailed study of the mechanical properties, it is revealed that silica may be replaced by DT and some rubbers may be filled by these powders.…”

In this work, a novel type of diatomite was prepared with a limited content of hindered phenol groups grafted on its hydrophobic surface. The obtained samples were characterized for their surface groups, particle morphology, pore structure, and thermal behaviors. Then, modified diatomite (MDT) was used in preparation of reinforced chlorinated butyl rubber (CIIR) composites by mechanical blending method. The powder of MDT can be uniformly dispersed in CIIR matrices and the compatibility was good. In addition, the MDT showed a positive effect on damping performance of CIIR composites. A blending ratio of CIIR/MDT = 100/10 presented the best damping performance and the damping temperature range (tan δ > 0.7) was extended from 60 to 70 °C. The variable temperature FTIR spectra showed the presence of hydrogen bonds between the hydroxyl groups and chloride atoms in the CIIR matrices, and a blue shift exhibited when these hydrogen bonds were dissociated. Hence, these CIIR composites provided good damping behaviors and supplied a novel and promising way for preparation of high damping rubber composites with broad temperature ranges.

“…In the majority of applications, rubbers need to be strengthened with reinforcing fillers to improve the failure properties in particular along with upliftment of other technical properties. [1] However, the degree of reinforcement grossly depends on the size of the fillers, surface functionalities and their state of dispersion and distribution in the rubber matrix. [2] The main two conventional reinforcing fillers used in the rubber industry are carbon black and silica.…”

Influence of partial substitution of carbon black with silica on mechanical, thermal, and aging properties of super specialty elastomer based composites

The reduction of the carbon black quantity in elastomeric composites is a massive requirement from environmental perspective and a huge challenge for industrial implementation. The present work consists of the replacement of half amount of carbon black with silica without compromising the basic properties along with ushering of superior characteristics of fluoroelastomer and silicone rubber blends. The comparative study of carbon black-silica hybrid filler (1:1 ratio) with carbon black and silica at different loadings shows much superior aging behavior and thermal stability compared with the other composites with unforeseen increment of tensile strength (56%). The fundamentals of rubber-filler interaction and reinforcement phenomenon of the hybrid filler composites have been determined by the correlation of the experimental findings with different models like Nicolais-Narkis, Nielsen, Guth, and Kerner model. Furthermore, enhanced compatibility between the two rubber phases has been observed in terms of T g shifting (3.8 C) and reduced FKM domain size (from 450 to 300 nm) in the silicone rubber matrix for hybrid filler composites. Morphological studies reflect the selected homogeneous dispersion of the carbon black in fluoroelastomer domain and silica in silicone rubber phase. These super specialty elastomeric composites can be used as oil and fuel resistant gaskets and O-rings for wide temperature range.

“…At present, some scholars have filled pure natural diatomite in various kinds of rubbers and the effect of modification is not significant [3]. In this work, a new, simple and green methodology to introduce a limited content of silanol groups on the surfaces of the silica and diatomite compound filler and fluorine rubber was studied to find the most suitable filler system for fluorine rubber and the modified fluorine rubber nanocomposites were prepared by using diatomite [4,5], carbon black and silica [6,7] as the reinforcement and filler and the coupling agents KH550, KH590 or Si69 [8] as the compatibilizer between the filler and fluorine rubber. The diatomite used is in disc shape with a very large specific surface area.…”

To find the most suitable filler system for fluorine rubber, a simple and green method to introduce a limited content of silanol groups on the surfaces of silica and fluorine rubber was studied. Fluorine rubber nano-composites were prepared by using nano-silica, diatomite and carbon black as the reinforcement and filler and the coupling agents KH550, KH590 or Si69 as the compatibilizer between the filler and fluorine rubber. The structure and morphology of the composites were investigated by Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). The results showed that the most suitable filler system for fluorine rubber was the diatomite and silica compound (8:12 mass ratio), the best coupling agent was KH550 at 2 parts per hundred rubber (phr). The modified compound filler was silanized with the coupling agent KH550 for fluorine rubber by FTIR analysis, the compatibility between the filler and fluorine rubber was improved by SEM analysis and further confirmed by thermogravimetric analysis to improve the thermal properties of fluorine rubber with the filler compound system.
