摘要: 提出了一种新的纤维表面处理方法和工艺, 将MPP 乳液引入黄麻纤维的表面处理。考察了NaOH 处理对黄麻纤维吸湿性和热稳定性的影响, 研究了NaOH 溶液及NaOH 溶液和MPP 乳液组合处理对黄麻纤维毡增强聚丙烯复合材料力学性能的影响。结果表明: 黄麻经NaOH 处理后, 吸湿率降低, 热稳定性提高; 黄麻纤维毡增强聚丙烯复合材料的力学性能明显提高, 表面涂覆MPP 乳液后, 力学性能更进一步改善。Abstract: A new method of pret reatment of jute f iber is put forward , where MPP emulsion was used in the pret reatment . Several issues were studied including the effect s of pret reatment of jute f iber with alkali solution on themoisture and thermal stability as well as the effect s of pret reatment of jute f iber with alkali solution and combinationof alkali solution and MPP emulsion on the mechanical properties of the jute f iber mat reinforced polypropylene. Theresult s show that the moisture and thermal stability of the jute f iber are improved and the mechanical properties ofjute f iber mat reinforced polypropylene are obviously increased af ter t reating with alkali solution. The mechanicalproperties of the composites are even better af ter t reating with combination of alkali solution and MPP emulsion.
