Description

一种气体辅助橡胶湿法混炼制备装置 技术领域
本发明涉及橡胶混炼技术领域，具体来说，涉及一种气体辅助橡胶湿法混炼制备装置。
背景技术
长期以来，橡胶工业使用的原材料一直是一种块状橡胶，这种块状橡胶不仅给搬运和配料带来不便，还需要切成小块称量，同时在混炼时也要消耗很大动力才能将其碾碎、混合，因此需要重型的炼胶设备，不仅消耗动力大，而且炭黑不易分散，炼胶次数多，周期长。此外，橡胶树所生产的是液态的胶乳，将胶乳凝固、干燥制备成块状的橡胶，不仅工序繁杂、周期长，而且还需消耗大量的人力、物力，浪费很多能源。
针对块状橡胶混炼时的种种缺点，湿法混炼技术应运而生。湿法混炼技术是指将经过预先加工的炭黑、白炭黑等填料制成水分散体，在液态下与橡胶胶乳充分混合，再经凝聚、脱水、干燥等过程生产橡胶混炼胶的方法。与传统的将干胶与炭黑、白炭黑等配合剂在密炼机中进行多段干法混炼完全不同。湿法混炼技术的最大的优点就是填料分散性好，硫化胶的物理机械性能好，能有效避免粉体填料的飞扬污染，利于环保，与其它配合材料的混合效果好，加工非常方便，能显著降低橡胶的混炼能耗和成本，并有利于连续混炼工艺的实现。
中国专利申请号201080052075.4中公开了制造胶乳凝块复合材料的方法及装置，包括凝固反应器的设备，所述凝固反应器具有混合部分和从进入端以逐渐增大的横截面面积延伸到开放的排放端的总体上管状的扩散体部分，所述设备的进一步特征在于结尾于注射孔的传输管，所述注射孔被调整和构造用于将流体在设置于所述进入端与所述开放的排放端之间的入口处传输到所述扩散体部分。其装置应用于胶乳复合材料的制备主要是利用管道直径变化产生混合效果。
中国专利申请号201310037190.X中公开了一种用于橡胶母炼胶的连续式制造方法的装置，其具体的技术方案为，凝聚器为具有一个或两个以上进料口的管式凝聚器。当经过精分散的橡胶/填料/添加剂/溶剂混合物在高速高湍流的状态下注入凝聚器时，由于速度十分高，根据流体力学及湍流流体力学原理，混合物内部压力急骤下降。在高剪切作用下混合物流将形成细小液滴。其混炼是利用装置的形状，液体在内形成高速高湍流进行混合。
以上两种混炼效果不太理想，针对相关技术中的问题，目前尚未提出有效的解决方案。

第一步：将配方中的填料、配合剂制备成各自的溶液，并且将该溶液配 置成均匀的水分散体。
上述各个溶液的制备具体包括：
1、天然胶乳溶液制备：取干胶含量60％的离心浓缩天然胶乳332g，在胶乳中加入668g蒸馏水，用搅拌棒搅拌，将离心浓缩天然胶乳稀释成干胶含量为20％的天然胶乳溶液。
2、白炭黑浆料制备：取高分散性白炭黑120g溶解于480g蒸馏水中，用玻璃棒搅拌使白炭黑完全溶解于蒸馏水中，浆混合好的白炭黑浆料用T25高速分散机在12000rpm下处理1min，再将白炭黑浆料放入行星式球磨机中研磨2h。
3、硅烷偶联剂溶液制备：取20g硅烷偶联剂Si69溶解于180g蒸馏水中，用玻璃棒搅拌均匀，再将Si69溶液放入行星式球磨机中研磨30min。
4、氧化锌溶液制备：取4g氧化锌溶解于76g蒸馏水中，用玻璃棒搅拌均匀，再将氧化锌溶液放入行星式球磨机中研磨30min。
5、硬脂酸溶液制备：取4g硬脂酸SAD溶解于76g蒸馏水中，用玻璃棒搅拌均匀，再将硬脂酸溶液放入行星式球磨机中研磨30min。
6、防老剂4020溶液制备：先将防老剂4020颗粒在行星式球磨机中研磨1h，研磨之后的防老剂4020为粉末状，取4g溶解于76g蒸馏水中，用玻璃棒搅拌均匀，再将防老剂4020溶液放入行星式球磨机中研磨30min。
7、促进剂D溶液制备：取2.6g促进剂D溶解于49.4g蒸馏水中，用玻璃棒搅拌均匀，再将促进剂D溶液放入行星式球磨机中研磨30min。
8、硫化体系溶液制备：取2.4g促进剂CZ和2g硫磺溶解于83.6g蒸馏水中，用玻璃棒搅拌均匀，再将促进剂D溶液放入行星式球磨机中研磨30min。
第二步：将以上得到的各种原料的水分散体分别装入对应的储料罐中。
具体地，将炭黑、白炭黑等填料和各种配合剂以及硫化体系制作成水分散体，将胶乳、填料浆料、各种配合剂以及硫化体系的水分散体分别放入8个储料罐15中，储料罐15与喷枪5通过导料管16连接，每一个储料罐15 对应连接一个喷枪5，由储料罐15为喷枪5供料。
第三步：将储料罐中的溶液在压力下从对应的喷枪中喷出，确保从喷枪中喷出的溶液被完全均匀雾化，并连续喷射到的反应器的混合室。
气源装置6通过导气管17与喷枪5连接，由储气罐18为喷枪提供气源，气源压力为0.5-3MPa可调，优选2MPa。混合室3下方放置有接料盘8，用以盛放反应之后的混合液液体。
具体喷射的时候，胶乳溶液、填料浆料溶液、各种配合剂及硫化体系的溶液经喷枪在3MPa压力下喷射之后被均匀雾化，且各喷枪5与水平面呈60°夹角向混合室3顶部喷射，被均匀雾化的胶乳溶液、填料浆料溶液、各配合剂及硫化体系溶液能够充分接触，达到良好的分散混合状态。
第四步：如图5所示，雾化后的各物料在混合室扩散并接触，混合后在混合室的内壁凝聚，并沿混合室内壁流出，得到橡胶混合物。
具体地，混合室3设计成椭球形状，相比于圆球形状的混合室3来说，椭球形混合室的混合区体积更大，使喷枪5喷出的物料在有效的距离范围之内被更加充分的雾化，被雾化的物料在较大的体积之内能够更加充分地接触，因此更进一步提高了混合效果。
雾化之后的各种溶液经充分接触之后便附着在混合室壁上，形成液滴，液滴在重力作用下沿着混合室壁向下流，经混合室底部出口流出，流入混合室下方的接料盘。最后将接料盘内的物料进行脱水干燥制得终炼胶，再将终炼胶硫化制得橡胶制品。
在保证物料充足的情况下，通过气源装置6不断地向喷枪5供气，并且控制压力保证经过喷枪喷射出来的物料为雾态，这样保证了混合的充分性，然后保证喷枪连续喷射，从而实现该装置的连续作业，实现连续化生产。
第五步：对S4步骤中获得的橡胶混合物进行絮凝、洗胶和脱水获得橡胶母炼胶。
具体步骤包括:将搅拌后的混合液加入一定量乙酸，进而胶乳混合液均匀 絮凝。将凝固之后的胶乳混合体放入洗胶机中进行脱水，同时用自来水对其进行冲洗、将经洗胶机脱水之后的胶片放入70℃的烘箱中干燥8h，再将烘箱温度调至148℃将胶片再烘2min，即可取出。
得到后的橡胶母炼胶可进行开炼机混炼及硫化。具体操作为：将烘干之后的胶片放到开炼机上进行补充混炼，在开炼机辊筒间隙最小状态下，将胶片在开炼机上过辊十次即可下片，得终炼胶、将制得的混炼胶在150℃、10MPa压力下在平板硫化机上硫化15min，即可得湿法硫化胶。
综上所述，借助于本发明的上述技术方案，将配方中各原料制备成溶液状态，通过喷枪将溶液均匀雾化，在混合室内进行扩散混合，以此实现湿法混炼效果，通过雾化提高物料接触的比表面积，提高湿法混炼效果；本发明所提供的装置结构简单，安装方便，设备投资少，占地空间小，操作简单方便，能耗较低，且可实现连续化生产；同时本发明提供的湿法混炼制备方法改善了工作环境，减少了环境污染，节省能源，同时加工工艺简单，可实现工业化生产。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
