称 TSP),利用 FTIR、 HNMR 对其分子结构进行了表征。以鞣后坯革的收缩温度及物理感官作为评价鞣制效果
的依据,通过单因素实验得到合理的鞣制条件:鞣剂 TSP 用量 25%(以绵羊灰皮质量计,下同),鞣制温度以 25、
40、50 ℃阶梯上升,每个温度鞣制 2 h,鞣制总时间为 6 h,通过提碱使浴液 pH 最终维持在 5.5~6.0。实验结果

Abstract: p-(4,6-Dichloro-1,3,5-triazin-2-yloxy) benzenesulfonic acid sodium salt (denoted as TSP) was
synthesized by one-step condensation reaction of cyanuric chloride and p-phenolsulfonic acid in the
1
presence of water. Its structure was characterized by FTIR and HNMR. Then, TSP was applied as tanning
agent. The shrinkage temperature and physical sense of the tanned leather were used as a basis for
evaluating the tanning effect in this paper. The reasonable tanning conditions were obtained by single factor
experiment: dosage of TSP 25% (based on the mass of limed sheep skin, the same below), tanning
temperature in three stages of 25, 40 and 50 ℃, tanning time of each temperature stage 2 h, total tanning
time 6 h and ultimate bath pH 5.5~6.0 by basification. The results indicated that the shrinkage temperature
2
of the crust leather could reach 78.4 ℃, the tensile strength was 14.15 N/mm , the tear strength was 36.44
2
N/mm, and the elongation at a specified load of 10 N/mm was 25.58%.

铬鞣法为制革工业中最主要的鞣制方法 ,其 统工艺条件下,铬鞣剂无法被皮胶原纤维完全吸收,
成革综合性能是目前其他鞣法所无法媲美的。在传 吸收率一般在 70%~80%,鞣制废液中会残存一定量
