In the tread compound of Green tire, silica dispersity is critical for obtaining high-performance rubber composites. Ionic liquids have been successfully applied in improving the dispersity of silica through chemical and physical interaction. However, recent research has found that ionic liquids are harmful to the ecological environment. Meanwhile, the price of them is high. In this paper, the deep eutectic solvents (DESs-Choline Chloride: urea) was synthesized successfully. Then it was directly introduced to prepare silica-filled styrene-butadiene rubber (SBR) compound via an in-situ method. The carbonyl group and amino in DESs could constitute a hydrogen bond with the silanol on the silica surface.The hydroxyl groups were able to react with the silanol groups. The amino groups in DESs could treat as a secondary facilitator, which accelerated the curing rate. The results showed that DESs improved the dispersity of silica effectively and strengthened the interaction between silica and SBR chains.Particularly, the comprehensive performance of the rubber vulcanizates improved with an optimal ratio of bis(3-triethoxysilypropyl)-tetrasulfide (TESPT) to DESs being of 1:1. In addition, the DESs will serve as a novel material in silica-filled SBR composites, which will expand its application in the tire industry.

“…They found that the dispersion of silica in SBR was improved with incorporation of BMI. [ 8 ] Consequently, the resulting modified composite with BMI showed an increase in the tensile properties compared to the unmodified one. In this way, Surya et al used amide of fatty acid, palmitamide, as a modifier for silica in silica‐filled SBR compound and studied its effect on the physico‐mechanical properties of the resulting compound.…”

“…[1,[5][6][7] Thus, modification of silica surface is an important step for its application in rubber. [8] Silane coupling agents especially bis (3-triethoxysilylpropyl) tetra sulfide (TESPT) has emerged as a good solution to improve the silica dispersion as it converts silica to more hydrophobic material. [1,6,7,9] This was done by reacting hydrolysable alkoxy groups of TESPT with the hydroxyl groups of silanols on the silica surface, and this led to turning silica to a hydrophobic material.…”

“…[1,6,7,9] This was done by reacting hydrolysable alkoxy groups of TESPT with the hydroxyl groups of silanols on the silica surface, and this led to turning silica to a hydrophobic material. [6] Although modification by TESPT is effective in improving the dispersion of silica as it improves the processability and mechanical properties of the obtained rubber compound, [8,10] it has some limitations. Among these limitations is that it requires a high mixing temperature (150 C) in order for the silanization reaction to occur between TESPT and silica.…”

In this study, cinnamaldehyde (CAD) was used as a filler modifier and antimicrobial material for silica‐filled styrene butadiene rubber (SBR) composite. CAD was used in different amounts to modify the silica surface. Fourier‐transform infrared spectroscopy (FTIR) was used to characterize the obtained CAD modified silicas. The modified silicas were mixed with SBR matrices using a laboratory two‐roll mill to produce modified silica‐filled SBR composites. The curing, mechanical, swelling and antibacterial properties of the resulting composites were studied and compared with those of the unmodified silica‐filled SBR composite. The surface morphologies of the obtained composites were also studied. The mechanical results showed that the use of 3 g of CAD resulted in a significant improvement in the mechanical properties of the resulting composite as its tensile strength, elongation at break and modulus at 100% increased by 144.9%, 105.1%, and 37.5%; respectively; compared to the unmodified composite. Furthermore, the antibacterial results showed that all the modified composites had a high activity against Gram+ and Gram− bacteria compared to the unmodified one, and this activity increased by increasing the amount of CAD. Accordingly, it is expected that these prepared composites can be used for medicinal purposes in the future.

“…Ionic liquids have also attracted people’s attention due to their good physical and chemical properties. 6–8 Du et al 9 studied the effect of a kind of ionic liquid, 1-butyl-3-methylimidazoliumtetrafluoroborate (BMI), on the properties of silica reinforced styrene-butadiene rubber (SBR). The results show that the ionic liquid can effectively improve the dispersion of silica in SBR, and can also improve the mechanical properties, wear resistance of the composites, the rolling resistance, and wet skid resistance of SBR.…”

The effect of deep eutectic solvent (DES) modified silica on the properties of nature rubber (NR) composites were investigated. The DES is an environment-friendly and low-cost solvent, which was prepared by mixing choline chloride and urea in a 1:2 molar ratio. The NR composites filled with DES modified silica were prepared and the properties were tested. The interaction between the DES and silica were characterized by Fourier transform infrared spectroscopy (FTIR), the interaction between silica and silica were tested by differential scanning calorimetry (DSC). The dynamic properties, such as rolling resistance and wet skid resistance, and were tested by dynamic mechanical analysis (DMA). Morphologies of the composites were characterized by scanning electron microscopy (SEM). The results indicate that the DES can interact with silica by hydrogen bond to improve the compatibility between the rubber and silica. When the content of DES was 3 phr, the tensile strength, modulus at 300%, tear strength, and the crosslinking density of the composites was increased. At the same time, the proper content of DES can reduce the rolling resistance of the vulcanized rubber while maintaining good wet skid resistance.
