摘　　要：将秸秆纤维在不同浓度碱溶液中浸泡不同的时间进行碱处理,观察NaOH溶液的浓度和浸泡时间对植物纤维石膏基复合材料力学性能的影响。实验结果表明,秸秆纤维碱处理可以提高植物纤维石膏基复合材料的力学性能,并通过正交试验得出最优试样中秸秆纤维碱处理的碱溶液浓度和浸泡时间,并初步探讨了秸秆纤维碱处理提高植物纤维石膏基复合材料力学性能的机理。Straw fibers are soaked in different concentration of alkali solution for different immersion time, examining the effect of concentration of NaOH solution and immersion time on mechanical property of plant fiber gypsum composites. The experimental results show that alkali treatment on straw fibers can enhance mechanical property of plant fiber gypsum composites, and through orthogonal test, the optimum alkali solution concentration and optimum immersion time during the process of alkali treatment are concluded. The mechanism of alkali treatment on straw fibers enhancing mechanical property of plant fiber gypsum composites are also discussed elementarily.
