Description
技术领域
本发明涉及橡胶材料技术领域，尤其涉及一种耐油耐腐蚀橡胶材料。
背景技术
橡胶材料属于非极性物质，根据相似相溶原理，橡胶材料往往易在油液中溶解，这样不利于橡胶材料在充满油液环境中使用，而某些橡胶材料需要在强酸强碱的环境下使用，上述两种使用环境会使橡胶材料的物理力学性能变化。为了提高橡胶材料的耐腐蚀和耐油的性能，人们在生胶制成橡胶制品的过程中，添加了各种配合组分，各种配合剂对橡胶制品的耐腐蚀和耐油性能影响甚大，目前，耐腐蚀耐油的橡胶材料仍然满足不了需求，如何制备一种耐腐蚀、耐油性能优异的橡胶材料成为目前需要解决的技术问题。
发明内容
基本背景技术存在的技术问题，本发明提出了一种耐油耐腐蚀橡胶材料，具有优异的耐油耐腐蚀的性能，而且耐热耐磨性能优秀，还具有较好的硬度。
本发明提出的一种耐油耐腐蚀橡胶材料，其原料按重量份包括：全氟醚橡胶30-40份，腈硅橡胶30-40份，丁苯橡胶20-30份，硫化剂DCP2.5-3.5份，硫磺粉3-4份，二乙烯基苯1-2.5份，三乙醇胺3-4份，氧化铝2-3份，氧化锌3-4份，氢氧化镁2.5-5份，硬脂酸4-6份，石蜡3-5份，炉法炭黑10-15份，纳米碳酸钙20-30份，改性酚醛树脂10-20份，硅烷偶联剂KH5604-6份，抗氧化剂10101.5-2.5份，其中改性酚醛树脂为采用妥尔油对酚醛树脂进行改性所得。
优选地，所述丁苯橡胶中结合苯乙烯的含量为为21-35wt％，门尼粘度(ML1+4，100℃)为48-66。
优选地，所述腈硅橡胶的侧链为β-腈乙基。
优选地，硫化剂DCP、硫磺粉、二乙烯基苯和三乙醇胺的重量比为3：3.5：2：3.5。
本发明采用如下工艺制备：将全氟醚橡胶、腈硅橡胶和丁苯橡胶置于密炼机中塑炼均匀，继续加入三乙醇胺、氧化铝、氧化锌、氢氧化镁、硬脂酸、石蜡、炉法炭黑、纳米碳酸钙、改性酚醛树脂、硅烷偶联剂KH560、抗氧化剂1010混炼均匀后，抽真空挤出得到混合物料，维持负压为0.6-0.9MPa；将混合物料置于冷却机中冷却至室温得到混合橡胶；将混合橡胶、硫化剂DCP、硫磺粉和二乙烯基苯投入到硫化机中混合均匀，再进行硫化，然后排胶、出片、冷却静置40h，得到耐油耐腐蚀橡胶材料。
本发明以全氟醚橡胶、腈硅橡胶和丁苯橡胶为主料，使本发明具有优异的耐油性能，而且耐酸碱腐蚀能力优秀；加入改性酚醛树脂，由于其是由妥尔油对酚醛树脂进行改性，使得改性酚醛树脂与主料相容性好，可以大幅提高本发明的硬度和耐热、耐磨抗撕裂性能，与氧化铝、氧化锌、氢氧化镁、炉法炭黑、纳米碳酸钙配合形成填充补强剂，进一步提高本发明的耐热耐磨性能；硫化剂DCP能使全氟醚橡胶、腈硅橡胶两个杂链橡胶产生交联反应，再辅以硫磺粉、二乙烯基苯作为助硫化剂，三乙醇胺作为活性剂，大大加速流程过程，提高交联程度和密度，大幅提高了本发明的耐热耐油耐酸碱腐蚀性能；而且三乙醇胺在本发明中还用作乳化剂和保湿剂，与硬脂酸、石蜡配合使用，提高了补强填充剂在主料中的溶解度和分散性；三乙醇胺还是PH平衡剂，由于硫化剂DCP为过氧化物硫化剂，在酸性条件下，会减缓硫化效率，而三乙醇胺呈弱碱性，调整制备过程中的PH值，保证整个硫化程度顺利进行。
具体实施方式
下面，通过具体实施例对本发明的技术方案进行详细说明。
在实施例1-3中，本发明提出的一种耐油耐腐蚀橡胶材料的原料按重量份如下表所示组成。
实施例1中所述丁苯橡胶中结合苯乙烯的含量为为21wt％，门尼粘度(ML1+4，100℃)为48，所述腈硅橡胶的侧链为β-腈乙基；实施例2中所述丁苯橡胶中结合苯乙烯的含量为为35wt％，门尼粘度(ML1+4，100℃)为66；实施例3中所述腈硅橡胶的侧链为β-腈乙基。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，根据本发明的技术方案及其发明构思加以等同替换或改变，都应涵盖在本发明的保护范围之内。
