TL;DR: In this article, the size distributions of primary particles and aggregate and agglomerate structures were determined using a ZetaPlus instrument using the dynamic light scattering method, and the structure and molecular dynamics of the nanocomposite, consisting of poly (p-phenylene sulfide) (PPS) and of precipitated silica, were studied using atomic force microscopy and nuclear magnetic resonance.
Abstract: Using a precipitation technique, silicas were obtained from sodium metasilicate solution employing an acidic agent. Alcohol solutions were used in the process of production of highly dispersed silicas, which resulted in partial blocking of the silica surface silanol groups. Moreover, studies on morphology and microstructure using transmission electron microscopy and scanning electron microscopy were performed. The size distributions of primary particles and aggregate and agglomerate structures were determined using a ZetaPlus instrument using the dynamic light scattering method. The structure and molecular dynamics of the nanocomposite, consisting of poly (p-phenylene sulfide) (PPS) and of the precipitated silica, were studied using atomic force microscopy and nuclear magnetic resonance. It was proved that during annealing the fragmentation of PPS agglomerates takes place. This phenomena probably resulted from repulsion forces existing between agglomerates and aggregates. Fragmentation in the polymer network probably resulted from repulsion forces between agglomerates and smaller aggregates.

TL;DR: In this paper, a turbo-charging rubber hose prepared from fluorine-containing silica gel is presented, which can meet the high heat-resistant property requirements, and meanwhile, the problem that the turbo charging rubber hose cannot meet the operating requirements after hot oil gas is mixed to cause the oil aging of the turbo-charged rubber hose, can be avoided.
Abstract: The invention relates to a turbo-charging rubber hose prepared from fluorine-containing silica gel. Serving as an inner layer material for the turbo-charging rubber hose, the fluorine-containing silica gel comprises the following components in parts by weight: 20-30 parts of methyl vinyl silicone rubber, 35-45 parts of fluorine rubber premix rubber, 5-7 pars of fluorosilicone, 2-3 parts of hydroxyl silicone oil, 1.5-2 parts of peroxide vulcanizing agent 101-45S, 0.5-1 part of crosslinking agent TAIC (triallyl isocyanurate), 2-4 parts of precipitated silica, 10-15 parts of carbon black N990 and 5-10 parts of magnesium oxide. By using the excellent heat-resistant property and oil-resistant property of the fluorine-containing silica gel and the good adhesive property of the fluorine-containing silica gel with the silicone rubber, the turbo-charging rubber hose can meet the high heat-resistant property requirements, and meanwhile the problem that the turbo-charging rubber hose cannot meet the operating requirements after hot oil gas is mixed to cause the oil aging of the turbo-charging rubber hose, can be avoided.

TL;DR: In this article, a rubber composition comprised of diene based elastomer, precipitated silica, particulate low molecular weight alcohol-adsorbing (e.g. alkanol-adsorbing) activated carbon and coupling agent comprised of at least one of organopolyalkoxysilane polysulfide (e) such as a bis(3-trialkoxyilylalkyl polysulide) and organoalkoxymercaptosilane.
Abstract: The present invention relates to a rubber composition comprised of diene based elastomer, precipitated silica, particulate low molecular weight alcohol-adsorbing (e.g. alkanol-adsorbing) activated carbon and coupling agent comprised of at least one of organopolyalkoxysilane polysulfide (e.g organopolyalkoxysilyl polysulfide such as a bis(3-trialkoxysilylalkyl polysulfide) and organoalkoxymercaptosilane. The invention further relates to a tire having a component of such rubber composition.
