改性明胶与皮革填充性能研究

Optimum Condition of Gelatin Grafting and Properties of Its Leather Fillers

通过丙烯酸乙酯对明胶的改性试验,确定了接枝聚合反应的影响因素,其中单体浓度的影响最重要,明胶的浓度次之。从27次试验并从旋转式运动粘度作目标参数,确立了接枝反应的适宜条件。利用所接枝物制备皮革填充计,填充效果表明,本填充剂改善了成苯多方面的性能。

Grafting ethyl acrylate onto gelatin, the factors affected grafting copolymeriaztion were determined, in where the concentration of monomer is the most important and the solute of gelatin is the second. The optimum condition of grafting were established by 27 trials and as the target parameter of movement viscosity. On the other, the fillers from this grafting product were prepared to leather. The filling effects were then showed that a number of properties of resultant leather are improved.
