Description
技术领域
本发明涉及一种橡胶材料制备领域，尤其是一种解放鞋用压延型草绿色橡胶围条胶的母炼工艺。
背景技术
当前解放鞋用压延型草绿色橡胶围条胶的炼制过程中，一般来说，采用直接将物料投入围条橡胶混炼工序的方法进行炼胶。这种方法存在着性能不稳定，橡胶因为着色剂等用量较小的材料飞扬损失，导致色相及性能相波动大，从而严重影响橡胶的质量水平。生产实际需要一种物料配比相对稳定的草绿色半成品着色剂母胶，以确保草绿色剂量稳定，使其形成稳定配比的预分散体。
发明内容
本发明的目的是：提供一种解放鞋用压延型草绿色橡胶围条胶的母炼工艺，它解决了围条色剂的最终配比不稳定的难题，实现草绿色剂存量均化恒定效果，达到这些材料分散均匀、橡胶色相性能均一的目的，以克服现有技术的不足。
本发明是这样实现的：解放鞋用压延型草绿色橡胶围条胶的母炼工艺，按照重量份计算，将45～50份松香丁苯胶，5～10份天然橡胶与3～5份石蜡加入密炼机中，压炼1分钟；再加入22～27份中络黄以及0.7～1.1份酞青绿，0.7-0.9份炭黑，压炼2分钟后，再加入28-33份中络黄，再压炼5分钟，然后排料到开放式炼胶机，在辊距为5～6mm下，包辊炼胶至颜色均匀一致，即获得解放鞋用压延型草绿色橡胶围条胶的母炼胶。
密炼机的炼胶温度为80～100℃。
开放式炼胶机的炼胶温度为45～60℃。
天然橡胶是2#标准胶。
炭黑：可用N330炭黑、N660炭黑、N220炭黑等具有稳定着色力的炭黑。
合成胶不易产生过炼，保证胶料工艺性能稳定性。
天然橡胶增加混炼胶的包辊性能。
本发明通过优化母胶的制备工艺，所获得的母炼胶能提高配合剂用量的稳定性，使混炼胶性能更加稳定。
为了进一步验证本发明的效果，进行了如下实验：
生胶配比选择试验
生胶的选择对母炼胶的制作起到关键作用。试验结果如表1、表2所示：
根据表1试验结果，选择天然橡胶与丁苯橡胶进行搭配使用试验，以获得最佳工艺性能，试验结果如表2所示。
根据表2结果，优选生胶配比为丁苯胶45～50份、天然橡胶0～10份。
二、配合剂用量依据
1．石蜡用量对母胶质量影响如表3所示。
根据表3试验结果，石蜡用量3-5份，能保证母胶工艺性能及分散效果处于最佳状态。
2．炭黑、酞青绿、中铬黄用量试验
从表1-表4试验结果得出，解放鞋用压延型草绿色橡胶围条胶合适的母胶配方为：合成胶45份,天然橡胶5份、石蜡4份、炭黑0.8份、酞青绿0.9份、中铬黄55份。
三、工艺条件与胶料质量对比试验
表5
根据表5试验结果得出，最佳炼胶及工艺时间条件为：将松香丁苯胶45～50份,天然橡胶5～10份加入密炼机中，压炼1分钟；再加入22～27份中络黄以及0.7～1.1份酞青绿，0.7-0.9份炭黑，压炼2分钟后，再加入28-33份中络黄，再压炼5分钟，然后排料到开放式炼胶机，在辊距为5～6mm下，包辊炼胶至颜色均匀一致，即获得解放鞋用压延型草绿色橡胶围条胶的母炼胶。
由于采用了上述技术方案，与现有技术相比，它解决了围条色剂的最终配比不稳定的难题，实现防老剂及草绿色剂存量均化恒定效果，达到这些材料分散均匀、橡胶色相性能均一的目的。本项目优点是：（1）减少炼胶粉尘污染量；（2）消除草绿色剂分散不均，提高分散效果；（3）增加配料准确性，防止胶料色差。（4）充分发挥防老剂对胶料耐老化的贡献率。（5）提高产品质量，包括外观质量和物理性能。
