发明背景
发明领域。
本发明涉及柔性层合结构，并且特别地涉及可以承受宽范围的温度和pH值的柔性、耐流体的层合结构。
相关领域说明
对于食品加工带和工厂和电厂中的伸缩接头来说，其需要可以承受宽范围的温度和pH的柔性、耐流体的材料。日益严峻的工业环境要求比迄今为止得到的材料更稳健的材料。
连续加工食品的方法是已知的，并且通常具有传输食品经过加热加工的传送机。在某些连续加热输送炉中，辐射热量由加热板提供至上述带经过的区域。此类带材料通常必须耐受500℉-550℉，偶尔偏移至600℉的连续使用温度。
如果传输系统使用快速降解的带会导致生产能力的损失。传送带的更新和传输系统的校准耗时且昂贵。停工期在损失制造产量方面是极其昂贵的，并且可能需要额外的备用生产线。
用于加工食品的传送带必须满足特定的FDA标准，包括CFR 177.1550，其禁止制备的食物与某些材料接触，如玻璃纤维。不幸的是，用于加工此类食物的传统传送带是在保护性含氟聚合物PTFE中浸涂和饱和的脆性织造玻璃纤维基材的复合物。此类复合物结构的扫描电子显微镜（SEM）图像提供了棒状玻璃丝和使复合物内部饱和的PTFE聚合物之间不良粘合性的视觉证据（图1和2）。SEM放大倍率下的横截面分析显示玻璃纤维容易与PTFE分离，并且易于断裂。
常称为PTFE涂布的玻璃纤维带由于表面破裂或弱的抗撕裂性经常过早地报废，导致玻璃纤维暴露接触到食品。在常规生产中，由PTFE涂布的玻璃纤维制成的传送带只能维持一两周。在所有实例中破坏的根本原因是存在玻璃纤维。
织造玻璃纤维基材由工业标准，Style 1528或7628玻璃纤维织物组成，该织物具有大约每英寸13磅的撕裂强度（切口），使用ASTM D2261-07测定。然而，上述带通常受到至少每英寸1磅的张力，这表示在典型的45英寸宽的带上，总的幅张力（web tension）是45磅。如果部分或所有的总负荷集中在裂缝的一点上，其远远超过了玻璃纤维织物的撕裂强度，且该基材通常会失效。
同样，对于伸缩接头，选择的材料类似地是PTFE涂布的玻璃纤维。根据定义，伸缩接头要求柔韧性，且经常要求抗振性，因为在内部玻璃纤维会将其自身切割成碎片，因此玻璃纤维只有非常有限的寿命。在图3和4中可以从视觉上明显地看出这一点，其中（作为用于SEM分析的样品制备的结果）横截面视图显示出一团混乱的脆性玻璃纤维，某些已断裂，且其余的纤维在弯曲过程中相互磨损而无法受到保护。
确实，含氟聚合物以前已经应用于PTFE基材（例如，参见Bragaw USP 4877683、Denny USP 4025679、Fagan USP 4324574、Griffin USP 6517919、Kelmartin USP 6770577、Sassa USP 4983434），但是这些制成包含多孔膜和粘合剂的多孔层合材料。使PTFE膜层合成其它的膜（Tippett, USP 7087136、Bragaw USP 4877683），和显示为使PTFE膜层合成PTFE涂布的玻璃纤维（Tippett, USP 7087136、Matthiessen US Pat. Pub. 2005/0164581）或暗示地层合成PTEF织造基材（Matthiessen US Pat. Pub. 2005/0164581），但是在高于PTFE熔点的如此高的温度下使得材料完全不是柔性的。
将PTFE膜层合成PTFE基材以制成柔性、非多孔结构的概念因为充分的理由在此之前没有公布。基于PTFE纤维的基材通常不被考虑为目前所设想的层合材料的良好的候选者，因为似乎不可能使其层合成氟碳膜，并获得良好的结果。即使不考虑层合困难，还应理解的是在各个加工过程中没有适当的热稳定性，当暴露在食品加工带的500℉-550℉的操作温度下时，该含氟聚合物基材会发生20-25%的收缩，导致在层合材料自身内部的不均匀收缩和所述带驱动和转动时的跟踪问题（tracking problems）。
因此，对于包括但不限于食品传送带和伸缩接头的用途，存在对于可以承受宽范围的温度和pH值，并且可以抗撕裂、耐流体和具有高度柔性的稳健材料的需求。

发明详述
本文所述柔性、非多孔层合膜结构可用于在一个宽范围的粘度、温度和pH下商业产品的加工。例如，层合膜结构适合于以下用途：包括但不限于食品制备传送带、伸缩接头材料、柔性导管和用于气态流体的传输。
本文所述的层合膜结构可用作传统PTFE涂布的玻璃纤维复合物的替代物。在某些实施方案中，本文的层合结构是由PTFE氟碳纤维或是已在高温下热稳定的PTFE-PFA杂混氟碳纤维的织造基材形成的，所述杂混氟碳纤维是在PFA的熔点（582℉，305℃）和PTFE的熔点（627℉，330℃）之间的温度下层合至预先形成的PFA膜。大约45℉（25℃）的温差使PFA能够在膜中熔融，且纱线在稳定低于纱线中主要聚合物（PTFE）的熔点的温度下产生。重要的是，未受影响的PTFE如整个织物基材一样保持了其自身的强度和结构柔性。熔融并在冷却后重新固化的PFA组分没有不利地影响该基材。在基材中PTFE的软化点被谨慎地避开，以免基材在冷却下变硬，并失去成品层合材料所需的性质。
如本文所用的术语“层合材料”表示结合在一起的多层材料，在此情况下表示膜与织物基材结合，相对于通过在基材内和遍布其整体的聚合物流体浆的饱和涂层，例如在浸涂中形成的“复合物”。
如本文所用的术语“膜”表示相对薄的聚合物层，其可以不同地描述为非细胞膜（non-cellular membrane）或非金属箔。
可以互换使用的术语“含氟聚合物”和“氟碳”表示具有多个强碳-氟键的基于氟碳的聚合物。
如本文所用的术语“织物”表示由纤维组成的织造、针织或非织造结构。
如本文所用的术语“非多孔的”表示在0.5" H2O的压降下使用ASTM D737测试方法所测得的通过层合材料的空气流速为每平方英尺的材料面积每分钟0立方英尺。
如本文所用的关于描述层合结构的术语“柔性的”表示其可以包覆或卷绕在相对窄半径的圆柱体棒上，并反复地还原成平直构型，并且在层合结构的性能上没有明显的变化。
如本文所用的术语“SEM”是扫描电子显微镜的首字母缩略词，表示在80倍或更大的放大倍率下的显微照片。
在一个制造本文所述的柔性非多孔层合结构的方法的实施方案中，提供织物作为基材，并且使氟化膜层合至织物。所述双带式压制层合机的反向旋转钢带将织物和氟化膜从层合发生的加热压板（heated pressure plates）之间的卷开台（off-wind stand）带走，任选地经过标准冷却板，然后到重绕台（re-wind stand）上。传统双带式压制层合机的概略图显示在图11中。
所述氟化膜是由以下树脂形成的膜：例如，全氟烷氧基共聚物（例如，来自E. I. DuPont de Nemours以商品名Teflon® PFA树脂市售的产品）或化学改性的聚四氟乙烯（PTFE）聚合物（例如，来自E. I. DuPont de Nemours以商品名Teflon® NXT树脂市售的产品）。
在图5和6中层合材料在SEM放大倍率下的横截面视图显示：
a. 所述膜流入到织造结构的间隙空间中，如同该结构已被涂布；
b. 所述膜封装了基材的表面和近次表面纤维；和
c. 所述膜形成光滑、未破损的表面。
此外，含氟聚合物纤维已部分软化和并入到膜层（L1和L2）之间的柔性物质（flexible mass）中。明显的是，例如当使用扫描电子显微镜观察时，膜层可以最低限度地辨别。虽然纱线中主要组分（PTFE）的软化点还没有达到，但当实际上它还没有软化时，其看起来也已经软化。对基材中的纤维进行检查，显示其相对于图1和2中能明显看出纤维的玻璃纤维或图8-10中能明显看出纤维的传统PTFE更凝胶态和在形状上无定形。
在实施方案中所得的100％含氟聚合物的层合材料提供了一个附加的益处，那就是其与CFR 177.1550能够100％相容，如果由于任何原因所述膜破裂，并且织造织物暴露到食物上，这将是有用的益处。在这种情况下，所述带保持适于使用，并且不需要立即停止使用或报废，而这是使用基于传统PTFE涂布的玻璃纤维复合材料的食品传送带会导致的情况。
所述杂混层合材料更抗撕裂、抗冲击，并且比传统PTFE涂布的玻璃纤维复合材料更柔韧。在根据本说明书形成的柔性层合材料的具体实施方案中，所述PFA/PTFE层合材料在用途中可以持续长至所使用的传统材料的10倍，且在某些实施方案中高于10倍的时间，所述用途包括例如，用于食品加工带和用于柔性密封件和接头。
合适的织物基材包括织造、针织或非织造结构，其包含含氟聚合物纤维、PTFE氟碳纤维，或其组合。合适的纤维描述在题为“由非-熔体-加工的聚四氟乙烯和全氟烷氧基制备的分散体纺丝含氟聚合物纤维”的相关美国临时专利申请No. 61/635,521中，其公开内容经过引用并入本文。分散体纺丝含氟聚合物纤维（Dispersion Spun Fluoropolymer Fiber）包括PTFE颗粒和PFA颗粒的共混物。所述含氟聚合物纤维通过以下步骤制备：形成PFA颗粒和PTFE颗粒的水性分散体，使该分散体与含有基质聚合物的基质聚合物水溶液混合，挤出该混合物进入凝固浴，和形成中间纤维结构。所述中间纤维结构经过烧结来分解基质聚合物，并使PTFE颗粒和PFA颗粒聚结成共混纤维。PTFE的基质纺丝法（matrix spinning process）将可观浓度的PFA引入具有对于常规织物加工，如针织和编织来说足够的拉伸性能的纤维结构中。将PFA引入基质纺丝PTFE纤维中得到PTFE的具有典型热学能力（最大连续使用温度）的真双组分纤维。此外，将PFA引入纤维基质可以给纤维提供较低的熔体组分。当上述较低的熔体组分在织物结构中时可以提供能够在相对于100％PTFE来说较低的温度和压力下使PFA膜层合的系统。在某些实施方案中，PTFE颗粒是非-熔体加工的，这表示当通过对于熔体-加工聚合物的标准熔体粘度测定方法，例如ASTM D -1238-00或其改进方法来测试时，没有检测到熔体流。
在一个实施方案中，一种杂混复丝纱用于形成织物基材，这通过Toray Fluorofibers USA以3：1的PTFE与PFA分散体的重量比来制备，所述杂混纱有两个软化点，一个对应于PFA，在大约305℃（582℉），较高的一个对应于主要的PTFE组分，在大约330℃（627℉）。上述纤维具有以下标称性质：圆形横截面、1200旦、单丝6.7旦、断裂强度1.2 gf/d、断裂伸长率50％和在300℃下30分钟时11.5%的收缩率，基于对合成纱的标准工业测试方法。测试纤维织造成具有59×59平衡经纬密度（balanced count）的1×2方平组织（basket weave）。使用标准拉幅设备和流程，使其以完全拉紧的状态在拉幅机上以20码每分钟的速率在600℉（315℃）下热固以生产尺寸稳定的织物。
然后，使用等压或等体积的通用双带式压制技术，在590℉（310℃）-620℉（327℃）之间的温度，优选600℉（315℃），并且在大于大约20 bar（290 psi），和在某些实施例中在30-50 bar（435-725 psi）的压力下，以能提供必要停留时间的适当速度，例如大约0.5-6.5米每分钟，使上述尺寸稳定的织物与标准1或2密耳的PFA挤出膜（通常由E. I. DuPont de Nemours或Saint Gobain生产）层合。在一个实施方案中，在进料速度为大约4 m/min时，达到大约10秒的停留时间。
出人意料的发现是温度和压力的适当组合导致具有高剥离强度、柔性、不渗透性和抗撕裂性的期望性质的层合结构。在温度和压力的适当组合下，上述膜“浸透”（wets out）并与基材紧密粘合，通过术语“浸透”描述一个视觉现象，其中不透明或半透明的织物或膜在加工过程中变得透明，例如，当织造玻璃纤维织物干燥时呈白色，当浸入环氧树脂时变得透明，使用常用的工业术语，它会“浸透”且看上去溶入到下面的树脂材料中。在过低的压力，或过短的停留时间下，例如在传统压延操作中，层合的PFA膜不会浸透，与基材进行弱结合，并且用手容易剥离。上述弱结合显示在图8-10中，其中膜没有与基材的纤维紧密结合，并且看起来漂浮在基材的表面上。
如图5和6所示，在适当的温度、压力和停留时间下层合的PFA膜紧密地布满在基材纤维的表面中。从图7可以看出织造基材中各个含氟聚合物纤维的原始横截面不再是圆形，而是已变形来填充其周围的空隙。在层合过程中，用裸眼可以看出膜在表面上浸透。表面膜和次表面纤维之间的结合非常完全，以致于将膜层中的一个从基材剥离的任何尝试等同于使基材本身破裂。这与通过传统压延形成的，从而在织造基材中各个纤维的原始横截面保持圆形的层合含氟聚合物形成鲜明对比，如图8-10中所示。应该注意的是，为了得到SEM横截面照片而产生的刀片切口可能使纤维束的端面变形。例如，在图9中，靠近照片中心的杂散纤维清楚地具有圆形横截面。
此外，本文所形成的层合结构的规格显著地小于其组分（膜和织物）的单独厚度规格的总和。例如，在图5-7中所示的层合材料由24密耳（0.024英寸）的织物夹心在大约2密耳（0.002英寸）的膜之间，层合前的总规格为0.028英寸。层合使此三层减少为0.0177英寸的平均规格，减少了大约40％。
要注意的是，在某些实施方案中，织物组分的规格可以减少，例如，使用200旦的织物纤维使规格低至5密耳。同样，400旦的织物纤维提供具有低至8密耳规格的织物组分。在这些实施方案中，对于分别使用200旦或400旦的纤维，4密耳或6密耳的预期层合结构规格来说，一个或多个膜组分可以是1密耳。较薄规格的层合结构对于需要更高柔性和/或更高传热速率的应用来说是有效的。
有利地，本文的层合结构对于其作为食品传送带、伸缩接头、柔性导管和形成气态流体的传输通道的预期用途是有效的。本发明层合结构的特别具体实施方案要求：
a. 膜没有表面蚀刻；
b. 在含氟聚合物膜的表面上或表面内没有用来在基材和膜之间产生强粘合性的中间分散体或胶合物，原纤维或结点，或类似的连接途径；
c. 没有填料；和
d. 除了为了尺寸稳定性来固定层合材料的外界环境之外，没有特别的冷却特征或方法步骤。
本发明的方法和结构已在上文和附图中进行了描述；然而，对于本领域普通技术人员来说修改是明显的，并且本发明的保护范围由随附的权利要求书来限定。
