摘　　要：在高温和添加含氮化合物条件下,对杨梅栲胶进行亚硫酸化改性,制备低温鞣制用的栲胶。测试结果表明,改性后栲胶的粘度值和盐析值均明显下降,收敛性缓和。定量分析和鞣制试验结果表明,相对于原栲胶,改性后栲胶的渗透性和结合能力受鞣制温度影响较小,渗透速度明显增加。The modified myrica rubra extract suitable for tanning heavy leather at low temperature tanning was prepared by sulfitation with compound containing nitrogen added. It was found thatthe modified myrica rubra extract's viscosity was significantly decreased and its astringency was gentle. Quantitative analysis and tanning experiments exhibited that the modified product has good penetrability and strong combinability at low temperature tanning.
