摘要
用土埋法研究了施胶剂对纤维素复合材料降解性能的影响。结果表明 :与未施胶样品相比 ,施胶样品在前期降解较快 ,而在后期降解较慢。从三个月降解的最后结果来看 ,添加施胶剂对材料降解有一定负影响。未施胶样品通过土埋法降解三个月 ,其降解率为 68% ,而施胶样品降解率在 55%～ 60 %之间。从经济和降解率考虑施胶量为 2 .
The effect of sizing agent on degradability of cellulose complex materials was investigated .The results showed that the water-based agent affects the degradability of this material .Sized samples degrade faster in the prophase of degradation and slower in the later stage than thatwithout sizing.Sizing agent exist negative effect on the degradability according to the final results of degradation for three mouths.The average DP of samples no sized decreased 68% after burying for three mouths while that of samples sized decreased 55%～60%.Adapt amount of size for preparing this kind of material is 2.9% for the reason of degradation and economy.
