摘 要: 简要介绍了铬鞣剂的发展历程及现状。创新性地提出了将超支化聚合物作为蒙囿剂和/或助铬吸收剂用于新型高吸收铬鞣剂的制备,以此提高铬的吸收率,促进铬在皮革中的固定,并在一定程度上预防皮革内Cr(Ⅲ)向Cr(Ⅵ)的转化,达到节约用铬,减少铬污染的目的。 It briefly described the development of chrome tanning agent, and innovatively puts forward an idea that introducing hyperbranched polymers into high - exhaustion chrome tanning agent as the masking agent and/or tanning auxiliaries. As a particu- lar additive, hyperbranched polymers with special molecular structure and unique properties could promote chromium absorption, reduce the consumption of chromium in tanning process and the pollution caused by chrome tanning wastewater, and to some ex- tent, prevent the conversion of Cr( Ⅲ ) to Cr( Ⅵ ) in leather.
