摘要

用剑麻-油棕混合纤维增强天然橡胶。通过改变纤维的重量含量和对生物纤维进行化学改性制备复合材料。分析了苯、甲苯和二甲苯三种不同类型的芳香族溶剂与橡胶复合材料的相互作用。纺织复合材料也通过将一片剑麻织物夹在两片预称重的橡胶片之间来制备。分析了纺织复合材料在苯、甲苯和二甲苯中的扩散行为。混杂生物复合材料和纺织生物复合材料的扩散机制不同。计算了所有复合材料的膨胀指数因子。发现溶胀主要取决于所使用的芳香溶剂和化学处理。化学改性的复合材料不易被溶剂渗透。

Comparison of Interaction of Aromatic Solvents in Hybrid and Textile Biocomposites

Natural rubber was reinforced with sisal—oil palm hybrid fibers. Composites were prepared by varying the weight content of the fibers and chemical modification of the biofibers. The interaction of three different types of aromatic solvents, namely, benzene, toluene, and xylene with the rubber composites was analyzed. Textile composites were also prepared by sandwiching a single sheet of sisal fabric between two pre-weighed rubber sheets. The diffusion behavior of the textile composites in benzene, toluene, and xylene was also analyzed. The mechanics of diffusion was found to be different for hybrid and textile biocomposites. The swelling index factor was also calculated for all the composites. Swelling was found to be predominantly dependent on the aromatic solvent used and chemical treatments. Chemically modified composites were found to be less prone to solvent permeation.

期刊介绍： The Journal of Elastomers and Plastics is a high quality peer-reviewed journal which publishes original research on the development and marketing of elastomers and plastics and the area in between where the characteristics of both extremes are apparent. The journal covers: advances in chemistry, processing, properties and applications; new information on thermoplastic elastomers, reinforced elastomers, natural rubbers, blends and alloys, and fillers and additives.
