| 摘 要： | 研究采用超速促进剂PX/硫黄/氧化锌硫化体系的无氨天然胶乳贮存性能、工艺性能、胶膜拉伸性能及自硫化机理。结果表明:无氨天然胶乳用异噻唑啉酮类衍生物保存剂对促进剂PX/硫黄/氧化锌硫化体系具有硫化协同效应;异噻唑啉酮类衍生物会使无氨配合胶乳在室温贮存时产生自硫化;适当调整促进剂PX/硫黄/氧化锌用量,可得到贮存性能、成膜性能和胶膜拉伸性能较好的无氨配合胶乳。

| Abstract: | The storage performance,processability,tensile properties of the latex film and self-curing mechanism of the ammonia-free natural latex using the fast curing system of accelerator PX/sulfur/zinc oxide were studied. The results showed that the isothiazolinone derivative preservative used for ammoniafree natural latex and the curing system had a synergistic effect on the curing. The self-curing of ammoniafree latex at room temperature was found with the presence of isothiazolinone derivative. By appropriate adjustment of the amount of accelerator PX/sulfur/zinc oxide,the ammonia-free latex with good storage performance and film formation performance was obtained,and the tensile property of the cured film was good. |
