Description

一种生产橡胶制品用的复合助剂
技术领域
本发明涉及高分子橡胶材料技术领域，具体涉及一种生产橡胶制品用的复合助剂。
背景技术
橡胶制品包括轮胎，输送带，胶鞋大底，胶管，胶带，胶辊，胶板，止水带，密封条，减震制品，杂件等，而橡胶制品在生产制造过程中存在以下几个缺陷：
1、由于橡胶制品的生产制造过程中，需要加入各种助剂，而这些助剂在橡胶中的溶解度很低，造成橡胶制品容易吐霜，不仅影响橡胶制品的外观，而且影响橡胶制品的品质；
2、另外橡胶在硫化过程中的活性剂，促进剂，橡胶制品的防老剂，橡胶制作过程中的分散剂，内脱模剂，在制造过程依次加入这些助剂，不仅操作繁琐，品种多样，计量不精确，容易产生不良次品；而且不环保，费时费力，不利于提高生产效率。
发明内容
本发明的目的是为了解决上述技术问题，提供一种生产橡胶制品用的复合助剂，将这些助剂复合到一起，一次性投放橡胶制品的工艺中，省时省力省钱，提高效率，减低成本，绿色环保。
为实现上述目的，本发明采用的技术方案如下：一种生产橡胶制品用的复合助剂，该复合助剂由以下重量百分比的原料组成：
该复合助剂由以下重量百分比的原料组成：
