“…Ismail and co-workers studied silica ash filled polypropylene/natural rubber blends; 28 Manna et al studied bonding between the silanol groups of silica filler and epoxy groups of rubber, 29 and Ishak et al investigated silica ash vulcanizates with a view to partially replace carbon black. 30 The first investigation found only moderate improvement in mechanical properties of polypropylenenatural rubber blends even after using amino-silane agents 28 indicating some improvement in fillermatrix interaction upon silanation.…”

Recycling rice hull ash: A filler material for polymeric composites?

Born more out of necessity, the "awareness-attitude" of our society has caused the channeling of technological developments toward immediate economic and ecological benefits. The polymer industry has a newfound interest in fillers from industrial by-products and other waste materials having potential "recyclability." This new class of fillers includes fillers from natural sources (e.g., natural fibers), industrial by-products (e.g., saw dust, rice husks), and a recent entry in the form of rice husk ash-an industrial waste material-obtained by burning rice husks. Their recyclability and utilization has become a major driving factor in their acceptance and employability, as well as low cost and abundant availability. However, their performance in composites and processing requirements has hindered their applicability within the current economic framework. The present article reviews the performance of rice husk ash, or silica ash, in polymeric composites. Silica ash, composed mainly of silica, is obtained after burning rice husks and is a major industrial waste material in rice growing countries. Optimism surrounds the application of silica ash as a potential filler in a variety of polymeric composites, however, its performance has been limited by its inherent characteristics. This paper emphasizes the need for better characterization of silica ash to obtain an in-depth understanding of its behaviour with the view to identifying suitable modifications to improve its performance as a filler. It is emphasized that poor understanding of silica ash as a

Nanosilica‐reinforced Epoxidized natural rubber nanocomposites: Effect of Epoxidation level on morphological and mechanical properties

Epoxidized natural rubbers (ENRs) with three different epoxide contents (i.e., 20, 35, and 50 mol% indicated as ENR20, ENR35, and ENR50, respectively) were prepared. They were then reinforced with 3‐methyacryloxypropyl trimethoxysilane‐modified nanosilica (MPTS‐SiO2). Influence of epoxide level in ENR molecules on morphological, mechanical, and dynamic mechanical properties of the ENR nanocomposites was investigated. The scanning electron microscopy results revealed larger agglomerates of SiO2 were found in the ENR composites with higher epoxide content. Furthermore, the strength and moduli of the ENR nanocomposites increased with increasing epoxide content. However, the optimal tensile strength and elongation at break were observed in the nanocomposites with the intermediate level of epoxide contents. The correlation between the strength properties and the interfacial silica‐matrix adhesion indicated that the maximum interfacial adhesion of the nanocomposites was observed in the nanocomposite with ENR35. Also, DMA results indicated stronger interaction between ENR35 and MPTS‐SiO2 due to higher storage modulus. POLYM. COMPOS., 38:1151–1157, 2017. © 2015 Society of Plastics Engineers

“…Consequently, increasing the filler content, which increases the filler activity, will increase the viscosity of the mixture and make processing more difficult. Thus, silane-based coupling agents are used to enhance both the dynamic and mechanical properties of silica-filled rubbers [2][3][4][5].…”

The utilization of nitrile glove waste will spark a great deal of interest in the rubber industry in developing cost-effective techniques to convert waste and used rubber into a processable form. Blends of styrene butadiene rubber/recycled acrylonitrile butadiene rubber (SBR/NBRr) reinforced at 85/15 blend with different ratios of a carbon black/silica (CB/Sil) hybrid filler (50/0, 40/10, 30/20, 20/30, 40/10, 0/50 phr) were tested either with or without the silane coupling agent, Si69. Results showed that the increased thermal stability of blends with Si69 is highly related to the formation of crosslinks between the filler. Thermogravimetric (TG) thermograms showed that the percentage of char residue for blends with Si69 was higher than without Si69. The differential scanning calorimetry (DSC) thermograms of both blends revealed a glass transition temperature (Tg) between 65.0 C and 66.9 C. At all blend ratios, the fatigue life of blends with Si69 was better than blends without Si69. After six months' exposure to natural weather, blends with Si69 exhibited better tensile properties, retention, and morphology compared to blends without Si69.
