| 中文摘要: |
| 采用NBR胶乳与明胶水溶液共沉的方法对NBR/明胶纺织皮辊胶料的混炼工艺及性能进行了研究。试验结果表明，采用明胶/NBR胶乳并用体系可明显改善明胶与NBR的混炼工艺，缩短混炼时间，提高胶料的弹性。在NBR胶乳中加入10 mL水稀释，可改善明胶的分散效果，胶料综合性能较好。明胶/NBR胶乳并用体系中填充适量的白炭黑，可弥补拉伸强度和硬度的损失，其用量以6份为宜。加入表面活性剂对甲苯磺酰胺，可降低胶料的体积电阻率，提高皮辊的抗静电性能。 |

| A study was made on the application of NBR latex and gelatin-water solution coprecipitation to improve mixing and physical properties of NBR/gelatin textile roller compound.The results showed that the mixing cycle reduced and the elasticity of compound improved by using gelatin/NBR latex blend；the dispersion of gelatin improved and better comprehensive physical properties of compound were obtained by adding 10 mL of water to dilute NBR latex；the loss of tensile strength and hardness could be compensated by adding 6 phr of silica to gelatin/NBR blend；and the volume resitivity of compound reduced and the antistatic property of roller improved by adding p-toluenesulfonamide as surface active agent. |
