摘要: 以AlCl3·6H2O为原料,通过微量加碱法制备了聚合铝PAC及聚合铝鞣剂PAT。实验表征了PAC的Aln(OH)m的结构特征;测定了PAT的溶解性和悬浊液中粒度分布与静置时间相关性;考察PAT的耐盐、栲胶溶液及加脂剂乳液的稳定性。结果表明三种材料的稳定性与时间相关。将PAT应用于制革的主鞣和复鞣工序表明,PAT作复鞣剂使用后坯革粒面细致,厚度显著增加,物理力学性能均有所提高。

Abstract: Using AlCl3·6H2O as a raw material, polyaluminum (PAC) and polyaluminum tanning agent (PAT) were prepared by a slight alkali addition method. The Aln(OH)m structure of PAC was characterized experimentally. The solubility of PAT and the correlation between standing time and the particle size distribution in the suspension were measured. The stability of PAT solutions mixed with salt,vegetable extract and fat-resistant emulsion was investigated. The results show that the stability of the three solutions is related to the storage time. The application of PAT to the main tanning and retanning processes of leather indicated that the grain surface was fine, the thickness was increased significantly,the physical and mechanical properties were improved.

Key words: polymeric aluminum, tanning agent, structure, retanning, application
