Abstract

Nonrubber components (NRCs) play an important role in the outstanding mechanical property of natural rubber (NR). The main inositol component of NRCs in natural rubber latex (NRL) is l-quebrachitol. In this study, the influence of l-quebrachitol on the properties of centrifuged natural rubber (CNR) was investigated. The NRL was centrifuged twice to remove most of the NRCs. After that, l-quebrachitol was added in the latex with per hundreds of rubber (phr) vary from 0% to 0.8%, and the vulcanized CNR were prepared. It is shown that the properties of vulcanized CNR were greatly changed, with T 90 reduced from 19 to 15 min, the tensile strength increased from 5 to 9 MPa, T g reduced by about 2°C, and the ability for strain-induced crystallization was enhanced. It was proved by FTIR results that l-quebrachitol was linked to the CNR crosslinking network with ester bond.

Abstract

Abstract: Strain‐induced crystallization of natural rubber (NR) can greatly influence the mechanical properties of NR blends. In this study, we investigated the effect of strain‐induced crystallization on the tear energy (G) of NR/styrene butadiene rubber (SBR) blends with different compositions and cross‐link densities. Using a shift factor, we could superimpose G of an SBR blend and an NR/SBR (1/9) blend onto a single master curve. In contrast, G of NR was split into two master curves. Although the master curve of G for the NR/SBR (3:7) blend was split, increasing the cross‐link density threefold made it possible to superimpose it onto a single master curve. Strain‐induced crystallization of NR in the NR/SBR blend did not occur as a result of decreasing the NR content, increasing the cross‐link density, or removing fatty acids. Together, these findings indicate that strain‐induced crystallization of NR plays an important role in the mechanical properties of the blend. [ABSTRACT FROM AUTHOR]

Abstract

The complexity and uncertainty of prediction on power supply and demand are analyzed in this paper, and studies the meta-synthesis method of man-computer integration from qualitative analysis to quantitative analysis. The meta-synthetic seminar hall system for power supply and demand research is designed and implemented. The system integrates power economy information, knowledge and experience of experts, computer simulation, and computing capacity. The mode of meta-synthesis from qualitative analysis to quantitative analysis is adopted to construct the intelligent system, which can support research, meeting and decision-making related to power supply and demand. And, the system can support experts to synthetically analyze and evaluate the important data depended by power supply and demand, e.g. policy environment and external condition, and the analytical results. More scientific, reasonable and quantitative scheme for decision-making can be obtained by this system.

Abstract

Effect of the nanomatrix structure on mechanical properties of natural rubber was investigated in relation to the strain-induced crystallization. Structure of natural rubber was analyzed through Fourier transform infrared spectroscopy, wide-angle X-ray diffraction measurement and transmission electron microscopy. The nanomatrix of the non-rubber components was found to be inevitably formed in natural rubber, in which natural rubber particles linking to fatty acids were dispersed in the nanomatrix of the proteins and phospholipids. The nanomatrix disappeared after deproteinization of natural rubber with urea. Tensile strength and modulus of natural rubber were reduced by removal of the fatty acids and the proteins, which resulted in disappearance of the nanomatrix structure. The effect of fatty acids on the crystallization of natural rubber in small particles as a dispersoid was proved by tensile test of blend of natural rubber and styrene butadiene rubber.
