“…34 In the past decade, considerable research has been related to the development of sol-gel-synthesized in situ silica-based rubber composites. In those publications, the solgel approach has been successfully used to synthesize silica in different rubber matrices such as NR, [35][36][37][38][39]41,42,44,45 methyl methacrylate-grafted NR (MMA-GNR), 40 styrene-grafted NR (ST-GNR), 43 SBR, [44][45][46] vinyltriethoxysilane-grafted SBR (VTES-SBR), [47][48][49] EPDM, 34,44,[50][51][52][53] hydrogenated NR (HNR), 53 NBR, 54 CR, 55 and epoxidized NR (ENR). 56 Furthermore, sol-gel science is very effective to produce in situ silica in different rubber blend systems such as NR and NBR 57,58 and NR and CR.…”

In recent years, the application of sol-gel science to industrial polymer research has offered advancements in rubber technology. The use of sol-gel–synthesized materials for the development of highly reinforced rubber composites is the most commonly adopted and popular method exercised by rubber scientists. This article comprehensively reviews the recent progress regarding preparation and properties of sol-gel–synthesized nanoparticles-based rubber composites. The pragmatic consequences of sol-gel–synthesized nanoparticles in rubber compounds are systematically described through rheological, mechanical, and thermal properties. Emphatic focus is given to understanding the reinforcement mechanism of rubber composites by the use of sol-gel–derived alkoxide silica as filler. The properties of rubber nanocomposites are usually dependent on the dispersion of sol-gel–synthesized nanoparticles into the rubber matrix. The results reviewed from prolific studies suggested that sol-gel science has tremendous potential to develop high performance rubber nanocomposites for future industrial application.

In this work, native emulsion polymerization styrene butadiene rubber (SBR) were first grafted by vinyltriethoxysilane (VTES) to SBR-g-VTES (VTES grafted SBR), second, the SBR-g-VTES were modified by different amount of TEOS (tetraethoxysilane) using in situ sol-gel method, at the last, the extra silica was added into the in situ modified SBR system to get the modified SBR/ silica composites using latex coagulation technology. The effect of different amount of TEOS on modified SBR/silica composites was also systematically studied, including the content of silica and utilization of silica, cure characteristics, physical mechanical properties and dynamic mechanical properties. The surface properties of modified SBR/silica composites were characterized by scanning electron microscope (SEM). It can be got that the grafting of VTES and in situ hydrolysis and condensation of TEOS can effectively inhibit the agglomeration and improve the mechanical properties of modified SBR/silica. It also can be found that modified SBR brings well physical and dynamic mechanical properties, wear resistance, and low rolling resistance to SBR, especially, when the TEOS is 3.0 g, the best overall performance of modified SBR/silica can be achieved. POLYM. COMPOS., 39:22-28, 2018. V C 2016 Society of Plastics Engineers INTRODUCTIONSynthetic rubbers are now commonly used in pneumatic tires. Tires must have a lot of requirements, especially for sufficient grip on the road, transmit steering forces to guide the vehicle and have as low as possible impact on fuel consumption [1]. According to investigation statistics, in the process of vehicle driving, the rolling resistance of tire is 20-30% of the total energy consumption of automobile. Furthermore, the rolling loss of tread is about 50% of the total energy consumption of tire [2].In the prevailing paper, carbon black (CB) and silica have been used as the main reinforcing fillers to resolve these problems that increase the usefulness of rubbers in tire [3,4].As discussed previously, silica can yield a lower rolling resistance at equal wear resistance and wet grip than CB. However, nano silica has a number of hydroxyl groups (silanol, Si-OH), which results in strong filler-filler interactions and adsorption of polar materials by hydrogen bonds [5]. The effective way is to use a coupling agent to modify the surface of silica, which can increase the filler-rubber interaction and improve silica dispersion in the composites, whereas, this method has two shortcomings, the first is that it is difficult to ensure each silica particle is organically modified by the molecules of silane coupling agent, the second is that the chemical bonding between rubber and silica cannot actually work quite right. As a result, researchers reported that in order to lower the rolling loss and higher wet resistance, introducing the functional groups which can either "passivate" free terminals or react with reinforcing filler into the macromolecular chains becomes a research focus in recent years [2].Up to now, there ...

Hydroxyethyl acrylate (HEA) was grafted onto styrene butadiene rubber (SBR) macromolecular chain by melt grafting method. Grafted structure was confirmed by Fourier transform infrared spectroscopy and 1 H spectra of nuclear magnetic resonance. In addition, the SBR-g-HEA/silica composites have been studied for their improved filler dispersion through hydrogen bonding interaction at the SBR/silica interface. SBR molecular chains and the silica interface was enhanced through coupling interaction at the hydroxyl modified SBR/ silica, at the same time. scanning electron microscope image of the cryo fractured surface of different SBR/silica composites and reduced Payne effect of rubber compound confirmed the silica particles have an even dispersion throughout the SBR matrix. The dynamic curves indicated the highest efficacy for wet and dry traction performances of SBR-g-HEA/silica composites comparing to unmodified reference sample. Meanwhile, the preparation of the composite does not need to add silane coupling agent to increase the capacity, there will be no volatile organic compounds produced by silanization reaction.Owing to the good properties such reduced energy and increased fuel efficiency, the SBR-g-HEA is an ideal eco-friendly material for green tire tread.
