用NBR胶乳改善NBR/明胶纺织皮辊胶料的混炼工艺及性能

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１０ｍＬ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

Improving Mixing and Physical Properties of NBR/Gelatin Textile Roller Compound

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.
