摘要
以充分利用木质素、减少其对生态环境的影响和带来良好的经济效应为主要目的,研究了木质素对填充丁基橡胶的结构与性能的影响。实验中使用腰果壳油(NC700)对木质素进行改性研究,后采用湿法浸泡的木质素填充丁基橡胶的方式对比采用腰果壳油改性的木质素填充丁基橡胶的方式,表征改性木质素的粒径大小,并研究不同品种与不同用量的木质素对丁基橡胶的性能影响,发现:腰果壳油改性后的木质素的粒径变小,具有更好的分散性能。经腰果壳油改性后的木质素填充的丁基橡胶,邵氏硬度、定拉伸应力都有明显的下降,而其断裂强度、撕裂强度都在改性木质素量为40~60份时候出现峰值;永久变形会变大。对比湿法浸泡的木质素填充的丁基橡胶的各项性能都随着木质素的用量增加而不断增大。
In order to make full use of the lignin, reduce pollution and increase economic effects. Experiments using cashew shell oil （NC700） to research modified lignin, then by contrast wet immersion lignin filled butyl rubber and cashew nut shell oil modified lignin filled butyl rubber, this paper studied the size of modified lignin, and the performance impact of different varieties with different amount of lignin on the butyl rubber.This paper found that the smaller the diameter of the cashew nut shell oil modified lignin, the better dispersion performance. Cashew nut shell oil modified Iignin-filled butyl rubber, Shore hardness, given tensile stress has a significant decrease, while the breaking strength, tear strength appeared a peak whenmodified lignin amount is 40 ~ 60; permanent deformation became large. The performance of the contrast wet soak the lignin-filled butyl rubber are increasing with the increase in the amount of lignin. The properties of butyl rubber filled with lignin in the wet process are increasing with the use of lignin.
