摘要
研究了以纸张为原料合成聚氨酯材料的方法 ,并分析了以牛皮纸为原料合成的聚氨酯材料的物理强度特性及其表面形态。研究结果表明 :牛皮纸经聚氨酯化处理后 ,可以使纸张中的纤维之间产生氨基甲酸酯型架桥结构 ,能提高纸张的物理强度 。
The method of synthesizing polyurethane material with paper were investigated Physical strength and surface condition of the polyurethane material derived from kraft paper were also analyzed It was found that carbomate bond was formed between cellulosic fibers in kraft paper treated with TDI The treatment could enhance the papers physical strength,especially in wet strength
