摘　　要：本文作者合成了皮革涂饰剂用有机硅改性聚氨酯水乳液，测定了改性前后乳液和胶膜的主要性能，结果表明：加入有机硅改性，可明显提高胶膜的力学性能和耐溶剂性能，用改性液处理过的皮革具有更高的耐湿擦级数，手感滑爽舒适。图１，表５。Authors synthesized the aqueous modified-silicone polyurethane solution for leather finishings, and main properties of the emusions and coating films pre-and after-modifications were also determined. Results show in this paper that the film characteristics of dynamics and solvent resistance have greatly improved, if modified with organo-silicon. Leathers finished with the modified finish emulsions give better wet fastness, and smooth and comfortable hands. 1 drawing, 5 tables and 5 refs.
