摘要

论文研究了大麻纤维(HF)不同的改性方式对天然橡胶增强效果的影响

通过使用大麻纤维来减少体系中的炭黑含量

在保证橡胶材料具有一定的力学性能的同时

降低大麻纤维增强天然橡胶(HF/CB/NR)复合材料的生热。结果表明:通过力学性能测试

表明加入一份碱处理的大麻纤维可以减少体系中3份炭黑

表现为二者材料的力学性能相当。通过压缩生热测试

发现加入一份碱处理与天然胶乳包覆复合处理的大麻纤维

使得HF/CB/NR生热明显降低

降低幅度为5.6%。大麻纤维的加入可明显降低payne效应

使材料在较高的应变下保持较高的刚度。

Abstract

This paper studied the influence of different modification methods of hemp fiber on the strengthening effect of natural rubber. By using hemp fiber to reduce the carbon black content in the system

the heat generation of hemp fiber reinforced natural rubber composite (HF/CB/NR) was reduced while the mechanical properties of rubber material were guaranteed. The results showed that the three parts of carbon black could be reduced by adding one part of alkali treatment to hemp fiber

and the mechanical properties of the two materials are equivalent. Through the compression heat generation test

it was found that HF/CB/NR heat generation was significantly reduced by 5.6% after adding hemp fiber treated with alkali treatment and coating with natural rubber latex. The addition of hemp fiber can significantly reduce Payne effect

so that the material can maintain a higher stiffness under higher strain
