Abstract

Orevac–crumb rubber–arabinogalactan composites of different composition are obtained under the action of shear deformations in a Brabender mixer. The structure, mechanical properties, and biodegradability of the materials are studied. It is shown that an increase in arabinogalactan content leads to increase in elastic modulus and decrease in elongation at break, as well as slightly affecting the tensile strength. The mass loss of the samples after exposure in soil defining their biodegradability rises with an increase in arabinogalactan content in the composites.

复合材料中的天然多糖阿拉伯半乳聚糖

摘要

在 Brabender 混合机中剪切变形的作用下获得了不同成分的 Orevac-橡胶屑-阿拉伯半乳聚糖复合材料。研究了材料的结构、力学性能和生物降解性。结果表明，阿拉伯半乳聚糖含量的增加导致弹性模量增加和断裂伸长率降低，并对拉伸强度产生轻微影响。样品在土壤中暴露后的质量损失定义了它们的生物降解性，随着复合材料中阿拉伯半乳聚糖含量的增加而增加。
