全球范围内，利用可用且廉价的自然资源制成的高性能材料的开发正在不断增加。报道并研究了一种新的天然橡胶溶液复合材料，其中含有大麦、玉米和麦秆作为生物填料。谷物秸秆填充弹性体的最新进展和趋势检验代表了一项科技创新。使用稻草作为弹性体复合材料的填料扩大了功能特性的范围并降低了生产成本。生物复合材料更加环保，并有机会增加秸秆管理的可能性，秸秆是一种有问题的农业废物。含有木质纤维素材料的橡胶混合物表现出有利的交联特征动力学。添加适量的填充剂可对天然橡胶硫化胶进行改性，提高复合材料的机械性能和阻隔性能以及在压缩应力影响下的阻尼能力。动态力学分析显示添加秸秆后硫化橡胶的 G' 值发生变化。这表明聚合物基质中存在强烈发达的填料网络，这确保了增强特性。没有观察到天然填料对抗热氧化老化的负面影响。 (C) 2017 Elsevier Ltd. 保留所有权利。
The development of high-performance materials made from available and cheap natural resources is increasing worldwide. A new solution composites of natural rubber, containing barley, corn and wheat straw as biofillers, was reported and researched. The latest developments and trend's exams of the elastomers filled with cereal straw represent a scientific and technological innovation. The use of straw as a filler for elastomer composites bradens the range of functional properties and reduces the costs of production. The biocomposites are more ecofriendly and give the opportunity to increase the possibility of straw management which is a problematic agricultural waste. The rubber mixtures containing lignocellulosic materials demonstrate a favorable characteristic kinetics of crosslinking. The addition of filler, in an appropriate amount, modified natural rubber vulcanizates, improving mechanical and barrier properties of composites and the ability to damp under the influence of compression stress. Dynamic mechanical analysis showed change in the G' values of the vulcanizates upon addition of straw. That indicates the presence of strongly developed network of fillers into polymer matrix which ensure of reinforcing character. The negative impact of natural fillers on resistance to thermo-oxidative aging was not observed. (C) 2017 Elsevier Ltd. All rights reserved.
