Description

防水通风管产品
技术领域
本发明一般涉及建筑材料产品，特别是涉及防水纤维风管产品和制造该产品的方法。
背景技术
管道和导管用于在建筑的加热，通风和空调(HVAC)系统中输送空气。在许多应用中，特别是在商业和工业的建筑中，使用柔性的隔热和隔音材料作为管道衬里。衬里提高了管道的工作热效率同时减少空气流动产生的噪音。管道衬里可以包括任何适宜的有机材料或无机材料，例如，像绝缘玻璃纤维等的矿物纤维。例如，典型的玻璃纤维管道衬里由密度为大约1.5至3磅/立方英尺(pcf)和厚度为大约0.5至2英寸的玻璃纤维衬垫制成。为了防止由于气流导致的纤维腐蚀，保温层包括其内部或“气流”表面上的一涂层。保温层的气流表面是穿过管道的传输空气表面而且与在最终管道组件的管道薄钢板接触的表面相对。在刷和/或管道内壁真空清洗过程中涂层也用作保护保温层。美国专利申请Nos.3861425和4101700提供了在管道内表面具有涂层的管道衬里的实例。可以在市场上购买的一些涂覆保温层的管道衬里有Vally Forge，PA的CertainTeed公司的商标为ToughGard的产品，Toledo，OH的Owens Coming Fiberglass公司的商标为Aeroflex和 Aeromat的产品，和Denver，CO的Johns Manville公司的商标为Permacote和PolycousticTM的产品。
其他隔热的HVAC系统使用的管道或者用刚性管道板或管制成或者用它们作为衬里。管道板是由树脂粘结的矿物纤维制成的刚性元件，而且其气流表面也可以有保护涂层。管道板一般具有大约3至6磅/立方英尺的密度和0.5至2英寸的厚度。从前述的管道衬里制造商处可以购买各种商标的涂覆的和未涂覆的管道板。不管在管道衬里上还是在管道板上，专用的防水涂层都增加了制造这些产品的成本和复杂性。
公知的微生物可以在有水分和养分的环境中生长同时许多种微生物对室内的空气质量(IAQ)有不利的影响。如果液态水渗漏到通风管的隔热层中，水会收集滞留在隔热层中并支持微生物的生长。
为了解决HVAC系统中微生物生长的问题，美国专利申请Nos.5314719、5379806、5487412和5783268中公开了在不渗透的管道衬里和/或管道板的输送空气的表面上或表面内施加抗微生物制剂。然而，这些专利没有提供防止水进入到管道中并在管道隔热材料中收集和滞留进而导致微生物生长的有效方法。另外，抗微生物制剂在非常有限的区域中有效。也就是，它们仅在其直接施加的区域内能防止微生物的形成。例如，美国专利申请No.5314719描述了大约1毫米的杀真菌剂的抑制区域。典型的管道衬里和管道板其隔热层厚度是大约0.5至2英寸。在这些产品中，这种有限的抑制区域对由通过外壁和管道接缝进入的水而浸透的管道隔热层导致的微生物的形成没有任何效果。
如果在通风管的气流表面施用隔热层产品，防水渗透涂层会抑制水进入到隔热层和伴随在其中的微生物的形成。美国专利申请No.3861425讨论了将这种涂层施用到由例如棉絮、垫、板或类似的玻璃纤维隔热介质构成的或加衬的HVAC管道上。虽然这种涂层可以带来防止纤维腐蚀和防水的好处，却增加了该产品及其制造方法的成本和复杂性。可以在纤维隔热产品形成后在其气流表面上施用涂层。这需要通过刷子、滚轴、喷枪或通过其他一些工具或方法在预先形成的隔热制品上施用涂层而后使涂层固化或干燥。这种成形后涂覆步骤延长了制造隔热产品所需的时间，而且不管手工还是机械化生产，为了确保涂层施用的均匀性必须仔细监视。
许多HVAC系统并未表现出其通风管有明显的纤维腐蚀因为它们在相对低的空气流速下工作。因此，它们不需要具有保护涂层或表面材料覆盖层的隔热产品。实际上，前述的隔热产品制造商有几种用于这类HVAC管道设备的未涂覆管道衬里和管道板。然而，未涂覆纤维隔热HVAC管道产品具有有限的防水性。所以，在它们受潮的情况下易于微生物的生长。
因此，对于未涂覆的防水纤维通风管隔热产品来说，存在一种用于制造该类产品的简单和经济的方法。
发明内容
本发明提供防水纤维通风管隔热产品和制造该类产品的方法。特别是，本发明提供一种包含树脂粘结玻璃纤维垫的管道板或管，该垫具有未涂覆、防水的气流表面。通过在用于粘结最接近气流表面的纤维垫的树脂中混合疏水剂，优选使管道板或管具有防水性能。这样，将防止管道内部的液态水进入隔热层中，因而降低了在隔热层中微生物生长的可能性。
参考下述优选实施方案和进行本发明过程的优选方法的详细描述，本发明其他详细内容、目的和优点将变得清晰。
附图说明
由下面的优选实施方案的描述，仅通过实施例并结合附图，本发明将变得更加清楚，附图中：
图1是根据本发明制造的隔热通风管产品的侧视图；和
图2是用于制造本发明的管道板的装置的局部断开的视图。
具体实施方式
参考图1，它表示本发明隔热通风管产品10的片断。产品10可以是刚性管道板或管，其中包含用适宜的树脂粘结的例如玻璃纤维、耐火纤维或矿物棉纤维的矿物纤维。通过参考图2可以理解，产品10是用一系列的树脂粘结的纤维叠层形成的，在最终的产品中，是作为一个连续的块而不是许多明显或不连续的层或薄层出现和存在。为了附图和解释的简明，尽管一般的刚性管道板或管包括三层或更多粘结层，在此公开的产品10仅包含第一和第二层12和14。用于粘结层12的纤维的粘结剂可以包括，但不限于，在美国专利申请No.5300562和5473012中公开的酚类粘结剂，它们所公开的内容在此引入作为参考。产品10具有大约3至6磅/立方英尺(pcf)的密度和大约0.5至2英寸之间的厚度。产品10的密度和厚度将根据特殊建筑安装的要求或需要的隔音和/或隔热性能来确定。
根据本发明，通过将疏水剂加入到层12和14中至少一层的粘结剂内，优选管道板或管具有防水性，在所述实施方案中，将疏水剂加入到层12中，该层暴露的表面限定了产品10的气流表面。这样，防止管道内部的液态水或其他溶液进入产品10中，因此降低了在隔热层中微生物生长的可能性。优选地，将箔/纤维制品/纸薄片制品或其他适宜的蒸汽阻滞层16附着或粘贴在与层12的气流表面相对的产品表面上，以防止周围环境中的水蒸气进入隔热层中。
参考图2，按照惯例，通过熔化例如玻璃的纺丝熔融材料，用许多纤维化装置22a-22f将熔融材料放入细纤维幕20中而在成形部分18中制造隔热层12和14。纤维幕进入成形防护罩24，其中将在水载体中(或水和粘结剂按顺序)的例如酚树脂的粘结剂喷到幕20上。在成形防护罩24中，在传送链、带或其他常规的驱动传送器26上像网一样堆聚并收集纤维。为了使层12具有疏水性，至少将纤维化装置22f装配成分配其中混合有疏水剂的粘结剂。网出现在成形部分18上后，将其输送至图中未示出的固化炉中来压缩并固化成所需的厚度和密度。而网在炉中时，同时加热层12和14以固化粘结剂而且使层之间相互粘合从而形成产品10的均匀块。优选地，使用图中未示出的加热压盘等在足够的压力下将层12与层14对齐进行挤压使层12和14压制在一起。产品10出现在固化炉后，将蒸汽阻滞层16施加到与气流表面相对的产品上。
在至少层12中使用的粘结剂优选包括有效量的例如硅、油、碳氟化合物、蜡等的至少一种疏水剂从而使产品具有防水性和耐包含适量溶剂的水溶液的特性。根据所选择的疏水剂，其有效量的范围是疏水剂与粘结剂的比例为大约1∶200至1∶5。根据第一个实施方案，适用于这一目的市售的疏水剂是由Midland，MI的Dow Coming公司制造的DC 347硅乳剂。当该制剂以大约1∶24的比例与酚树脂粘结剂混合表现出良好的防水特性。适于与酚树脂一起使用的可选择的疏水剂包括Fairfax，VA的Mobil Oil公司销售的商标为Mulrex的油乳剂，和Columbus，OH的Borden Chemical Inc.销售的原料号为SL 849的油。当BordenSL 849油以1∶6的比例与酚树脂混合时表现出良好的防水特性。
另外，当被制成平面管道板时，尽管在此未图示出，产品10也可以通过任何本领域公知的适宜技术制成为圆管形状，这样制成产品同时起到隔热管道管或圆管形管道垫的作用。
表1描述了根据本发明制成的产品10与CertainTeed公司生产的未改性Ultra*DuctTM板的控制样品的抗液体特性的比较。使用与Intemational Nonwoven &Disposables Association(INDA)标准对憎醇数IST 80.6-92所进行的相同测试来评估上述产品，上述测试的目的是测量用酒精和酒精/水溶液湿润和浸渍的非编织纤维的防水性。憎醇性作为测试材料表面的表面能量或斥水性的大致评估。水和异丙醇溶液抵抗时间是表示去离子水的2ml试样或以所述的量与异丙醇混和的去离子水的时间。
表1
试样 标识 水抵抗时间(小时) 异丙醇溶液抵抗时间(小时/分钟)
10％  20％
Ultra*DuctTM管道板 控制 24+ ＞1小时 ≤1分钟
改性的Ultra*DuctTM管道板(用DowComingDC 437硅) 产品10 24+ ＞1小时 ＞30分钟
改性的Ultra*DuctTM管道板(用BordenSL849m油) 产品10 24+ ＞1小时 ＞30分钟
如表1所示，控制和产品10都表现出超过24小时的抗水时间。尽管在表1中未示出，对于具有溶剂浓度为30体积％或更高的异丙醇水溶液来说，所有产品抗液体时间都可以忽略不计的。然而，对于20％的异丙醇溶液来说产品10的抗液体时间明显比控制的时间长。
尽管出于例证的目的已经详细描述了本发明，应该理解，这些详细描述仅是出于该目的，在不背离由权利要求所限定的本发明的精神和范围的前提下，本领域的普通技术人员可以作出各种改进。
