“聚合物”是指包含互聚的二价单体单元的宏观结构。聚合物的数均分子量(Mn)为至少50,000道尔顿、至少100,000道尔顿、至少300,000道尔顿、至少500,000道尔顿、至少750,000道尔顿、至少1,000,000道尔顿或甚至至少1,500,000道尔顿并且此类高分子量不引起聚合物过早胶凝。
而且,在本文,由端点表述的范围包括该范围内包含的所有数值(例如,1至10包括1.4、1.9、2.33、5.75、9.98等)。
而且,在本文,表述“至少一个”包括一个及大于一的所有数字(例如,至少2、至少4、至少6、至少8、至少10、至少25、至少50、至少100等)。
本申请涉及非晶态全氟化聚合物,其用于全氟弹性体胶中。全氟弹性体胶随后固化以形成全氟化弹性体。本公开的非晶态全氟化聚合物(本文中被称为全氟化聚合物)包含酸性端基。
全氟化弹性体用于遭遇恶劣环境的多种应用中,特别是其中发生暴露于高温和腐蚀性化学品的最终用途。在半导体行业中,全氟弹性体在需要抵抗NF3等离子体的工艺中使用。然而,该行业对尤其是金属离子和磷周围的材料纯度有严格要求。
全氟弹性体的高温耐受性和耐化学性可归因于形成聚合物主链的主要部分的共聚全氟化单体单元的稳定性和惰性。全氟化聚合物通常包含少量较不稳定的共聚固化位点单体,其促进全氟化聚合物的有效交联和固化化学。其中引发和终止聚合的聚合物链的末端(本文中被称为端基)也可包含反应性基团,其衍生自引发剂、链转移剂、分子量调节剂和/或聚合期间存在的其它化合物。
如果全氟聚合物包含性质为酸性的端基,则后续过氧化物固化期间和/或之后的聚合物的性能可受影响。因此,传统上,已经将稳定化合物加入全氟弹性体胶中以稳定这些酸性端基并改善例如所得全氟弹性体的压缩永久变形。这些稳定化合物通常包括例如金属氢氧化物(诸如氢氧化钙和氢氧化锶);金属氧化物(如氧化镁、氧化铅、氧化钙、氧化锌);金属碳酸盐(诸如碳酸钡、水滑石和碳酸钙);或者含磷盐(诸如三苯基苄基氯化)。然而,在一些应用中金属和磷原子是不可取的,因为其可污染弹性体用于其中的工艺。

本公开的全氟化聚合物包含酸性末端基团。这些酸性末端基团可通过基于傅里叶变换红外分析(FTIR)的积分吸光度比方法来测定,并且依赖于全氟化弹性体胶的压膜的FTIR谱中突出峰值下的基线校正的积分吸收。所述方法公开于下文并且更详细地在美国专利6,114,452(Schmiegel)和8,604,137(Grootaet等人)中有所论述,其以引用方式并入本文。
在本公开中,检查FTIR光谱的四个不同区域。
首先,测量介于约1620cm-1至1840cm-1之间的最突出峰值的积分吸光度。这些峰值对应于可归因于存在于聚合物中的羰基部分,包括羧基、羧酸酯和酰胺基团的吸光度。
其次,测量介于约1755cm-1至1797cm-1之间的最突出峰值的积分吸光度。这些峰值对应于可归因于存在于聚合物中的羧酸基团的吸光度。
第三,测定介于2220cm-1和2740cm-1之间的C-F拉伸泛频,其指示样品的厚度。该值用于将羰基和羧酸峰值的积分吸光度基线校准(或归一化)。
如果全氟化聚合物包含腈基团(诸如腈固化位点),则测量介于约2232cm-1至2277cm-1之间的最突出峰值的积分吸光度。然后从C-F拉伸泛频值中减去该值,因为C-N拉伸与C-F拉伸泛频重叠以产生“校正的C-F拉伸泛频”。
然后积分吸光度值通过将羰基积分吸光度除以C-F拉伸泛频(或如果存在腈,则校准的C-F拉伸泛频)以产生羰基积分吸光度比来测定。在一个实施方案中,本公开的全氟弹性体胶的羰基积分吸光度比为至少0.060,或甚至0.065。在另一个实施方案中,羧酸积分吸光度比通过将羧酸积分吸光度除以C-F拉伸泛频(或如果存在腈,则校准的C-F拉伸泛频)以产生羧酸积分吸光度比来测定。在一个实施方案中,本公开的全氟弹性体胶的羧酸积分吸光度比为至少0.012,或甚至0.015。
全氟化弹性体胶的交联可用过氧化物固化体系(或固化剂)来执行。
过氧化物固化剂包括有机或无机过氧化物。有机过氧化物是优选的,尤其是在动态混合温度下不分解的那些。
通常通过使用有机过氧化物作为交联剂并在需要时使用交联助剂,诸如甘油的二烯丙基醚、三烯丙基磷酸、己二酸二烯丙基酯、二烯丙基三聚氰胺和异氰尿酸三烯丙酯(TAIC)、异氰尿酸三(甲基)烯丙酯(TMAIC)、氰尿酸三(甲基)烯丙酯、聚异氰尿酸三烯丙酯(聚-TAIC)、苯二甲基-双(异氰尿酸二烯丙酯)(XBD)和N,N'-间亚苯基双马来亚胺,可以执行使用过氧化物的交联。有机过氧化物的示例包括过氧化苯甲酰、二枯基过氧化物、二-叔丁基过氧化物、2,5-二-甲基-2,5-二-叔丁基过氧己烷、2,4-二氯过氧化苯甲酰、1,1-双(叔丁基过氧)-3,3,5-三甲基氯己烷、叔丁基过氧异丙基碳酸酯(TBIC)、叔丁基过氧2-乙基己基碳酸酯(TBEC)、叔-戊基过氧2-乙基己基碳酸酯、叔-己基过氧异丙基碳酸酯、碳过氧酸、O,O'-1,3-丙烷二基OO,OO'-双(1,1-二甲基乙基)酯、叔丁基过氧苯甲酸酯、叔-己基过氧-2-乙基己酸酯、叔丁基过氧-2-乙基己酸酯、二(4-甲基苯甲酰基)过氧化物、月桂基过氧化物和过氧化环己酮。其它合适的过氧化物固化剂在美国专利5,225,504(Tatsu等人)中列出。所用的过氧化物固化剂的量通常将为0.1至5重量份每100份全氟化聚合物,优选地为1至3重量份每100份全氟化聚合物。其它常规的自由基引发剂适合与本公开一起使用。
该交联剂和交联助剂各自可以常规已知量使用,并且所用的量可通过本领域的技术人员适当地测定。参与交联的这些组分中的每种的使用量可以为(例如)每100质量份全氟化聚合物约1质量份或更多、约5质量份或更多、约10质量份或更多、或约15质量份或更多、和约60质量份或更少、约40质量份或更少、约30质量份或更少、或约20质量份或更少。参与交联的组分的总量可以(例如)为每100质量份全氟化聚合物约1质量份或更多、约5质量份或更多、或约10质量份或更多、和约60质量份或更少、约40质量份或更少、或约30质量份或更少。
例如,出于增强强度或赋予功能性的目的,可以将常规辅助剂诸如例如填料、加工助剂或着色剂添加到所述组合物。
此类填料包括:有机或无机填料,诸如粘土、二氧化硅(SiO2)、氧化铝、铁红、滑石、硅藻土、硫酸钡、硅灰石(CaSiO3)、碳酸钙(CaCO3)、氟化钙、氧化钛、氧化铁和炭黑填料、聚四氟乙烯粉末、PFA(TFE/全氟乙烯基醚共聚物)粉末、导电填料、散热填料等可被作为任选组分添加到所述组合物。本领域技术人员能够选择所需量的特定填料来实现硫化化合物的期望物理特性。填料组分可以产生能够保持优选弹性和物理张力(如由伸长率和抗拉强度值所指示的)并同时保持期望特性诸如在较低温度(TR-10)下的回缩的化合物。
在一个实施方案中,组合物包含少于约40重量%、30重量%、20重量%、15重量%或甚至10重量%的无机填料。
所述混合物可以然后诸如通过挤出或模制进行处理和成型,以形成各种形状的制品,诸如由本公开的组合物构成的片材、软管、软管衬里、O形环、垫圈或密封件。然后可以加热成型制品以固化凝胶组合物并形成固化的弹性体制品。
通常在约120℃-220℃的温度下,优选地在约140℃-200℃的温度下对配混混合物施压(即加压固化)约1分钟至约15小时,通常为约1分钟至15分钟的时间。在模制组合物时,通常使用约700kPa-20,000kPa,优选地约3400kPa-6800kPa的压力。首先可以用脱模剂涂覆模具并进行预烘干。
模制的硫化橡胶可在约140-240℃的温度下,优选地在约160-230℃的温度下于烘箱中进行后固化约1-24小时或更长的时间,这取决于样本的截面厚度。对于厚的部件,在后固化期间,通常将温度从所述范围的下限逐步升高到期望的最高温度。所用的最高温度优选地为约260℃,并且要在该值下保持约1小时或更长时间。
压缩永久变形是一旦移除力全氟弹性体就保持的变形。一般来讲,压缩永久变形值越低越好(即,材料的较少变形)。在本公开的一个实施方案中,在不具有传统稳定化合物的情况下制得的并且包括包含至少一个唑部分的化合物的固化的全氟弹性体具有超过在不具有包含至少一个唑部分的化合物情况下制得的相同固化的全氟弹性体的改善的压缩永久变形。
