摘　　要：四羟甲基硫酸膦(THPS)与Fe(Ⅱ)形成的二元体系进行结合鞣制后,可提高成革收缩温度。试验用THPS与几种Fe(Ⅱ)盐结合鞣制浸酸山羊皮,测定比较不同成革的收缩温度、耐老化性、物理机械强度等理化性质,寻找一种最适宜与THPS结合鞣的Fe(Ⅱ)盐,即THPS与Fe(Ⅱ)形成的配合物最稳定,抗氧化性最强。结果表明:THPS与硫酸亚铁结合鞣后的成革性能最好,收缩温度为90.3℃,成革撕裂强度23N/mm,伸长率35%,老化试验证明FeSO4-THPS结合鞣成革的耐老化性,优于其他3种Fe(Ⅱ)盐的结合鞣制。The stable complex can be formed by THPS and Fe （ Ⅱ） salts, which could improve the shrinkage temperature of tanned leather. The pickled goat skins were combined tanned with THPS and several Fe （ Ⅱ ） salts and the shrinkage temperature, assistance to aging and physical - chemical properties were determined. The results indicate that THPS and ferrous sulfate （ FeSO4） is the best tanning method. The shrinkage temperature of tanned leather is 90. 3℃, tensile strength is 23N/mm, elongation rate is 35%, and assistance to aging property of THPS - FeSO4 combination tanning is better than that of other several studied tanning combinations.
