层压管绝缘胶布的制造方法
摘要：
本发明公开一种层压管绝缘胶布的制造方法，包括：胶布进入胶槽进行第一次浸胶，浸胶率控制在30～50％左右，进入烘箱烘干，完全固化，烘箱底温设定为90～135℃，烘箱顶温设定为140～170℃，第一次浸胶使胶可溶性控制在0～5％；胶布进入胶槽进行第二次浸胶，浸胶率控制在15～40％左右，胶布进入烘箱烘干，烘箱底温设定为50～120℃，烘箱顶温设定为85～120℃，第二次浸胶使胶的可溶性控制在90～95％；由收卷装置将胶布收卷，整个过程中胶布经导辊运行，运动速度控制在1～8m/min。本发明使产品的耐电压性能比传统工艺生产的产品明显提高，达到湿法缠绕生产工艺的产品性能，接近真空浸胶工艺生产出的产品。
摘要（英）：

The present invention discloses process of making insulating adhesive fabric for laminated pipe. The process includes the following steps: the first time of glue dipping in the glue dipping rate of 30-50 wt% and glue solubility of 0-5 wt%, and stoving to cure glue in a stove of bottom temperature 90-135 deg.c and top temperature 140-170 deg.c; the second time of glue dipping in the glue dipping rate of 15-40 wt% and glue solubility of 90-95 wt%, and stoving to cure glue in a stove of bottom temperature 50-120 deg.c and top temperature 85-120 deg.c; winding the dipped adhesive fabric with one winder; and running the adhesive fabric during the process in the speed controlled in 1-8 m/min. The process can produce insulating adhesive fabric with high voltage resistance.
