LB型蛋白鞣剂应用性能研究

本文分别研究了LB型蛋白鞣和复鞣性能，该鞣剂由胶原纤维水解物通过苯酚磺化产物和醛类缩合改性而成。主鞣实验结果表明该鞣剂只具有微弱的主鞣性能，不适合用于主鞣过程。复鞣实验结果表明，当LB型蛋白鞣剂用量在4%以下时，经其复鞣的皮革身丰满、柔软，有较好的弹性，发泡感强，皮革增厚明显，有很好的填充效果和良好的选择填充性，同时物性实验显著经此鞣剂复鞣的成品革物性指标均能达到或超过行业标准，说明该鞣剂是一种优良的新型皮革复鞣材料。

Application Properties of LB-type Protein Syntan

This study on the tanning and retanning properties of LB type protein syntan respectively was synthesized by the collagen fiber hydrolysates with phenol sulphonate and aldehydes.The results of the main tanning experiments showed that LB type protein syntan only had a faint tanning property and was not suitable for main tanning process.The leather after retanned with more than 4% LB type protein syntan had good fullness,softness,elasticity and good vesicant feel and the thickness of the leather was obviously increased,which showed that LB type protein syntan had good filling effect and favorable selective filling property so it is a good new fype of reanning material for leather making process.
