磺甲基化蛋白填料的合成及性能研究

以工业明胶为原料,采用磺甲基化技术合成蛋白填料,并对其物化性能如溶解性、pH值等,和磺甲基化蛋白填料的用法进行了研究。试验表明:通过该方法合成的蛋白填料在水中有很好的溶解性能,而且在复鞣填充时使用具有优良的填充性能。填充后的革手感丰满、柔软且粒面细致,尤其可以显著地改善皮革的松面情况,减小皮革的部位差,改善革的手感,提高成品革的质量与档次。

Studies on the synthesis and application of protein filling agent synthesized by sulfomethylation

The protein filling agent was synthesized by the technique of sulfomethylation based on the industrial gelatin. At the same time, the properties e.g. solvent, pH value etc, and the methods of application of the protein filling agent were studied. By the experiments, it shows that the protein filling agent has better soluble property and better filling properties in the re-tanning and filling procedure, especially modify the loose grain of the wet-blue leather remarkably,lessen the difference of different parts of the wet-blue, improve the quality and grade of leather.
