采用球磨法、气流粉碎法、喷雾干燥法分别处理酶解木质素(EHL),其中气流粉碎酶解木质素的比表面积最大,达到6.311 m2/g,但仍然远低于炭黑N660的比表面积.将3种预处理方法制备的酶解木质素分别与炭黑对丁腈橡胶(NBR)进行复合补强,发现气流粉碎EHL的比例为50％的硫化胶的力学性能最优:拉伸强度、扯断伸长率比球磨法的分别高出17.28％,11.11％.该硫化胶的拉伸强度(20.44 MPa)、撕裂强度,比纯炭黑/NBR的分别略降低22.96％,12.03％;而扯断伸长率则提高28.50％,胶料仍具有优良的力学性能.但是随着复合补强体系中酶解木质素比例的逐步提高,NBR硫化胶的拉伸强度、撕裂强度都呈下降趋势.
