Abstract
本发明涉及具有低水可浸出氯化物含量的矿物纤维产品,其适合作为非腐蚀性隔热体和/或隔音体材料。
Description
技术领域
本发明涉及矿物纤维产品和矿物纤维产品的用途。
背景技术
矿物纤维产品(也称为矿棉产品)通常包括矿物纤维(也称为人造玻璃质纤维(MMVF)),例如玻璃纤维、陶瓷纤维、玄武岩纤维、矿渣纤维和石纤维(岩纤维),它们通过固化的热固性聚合物粘结剂材料粘结在一起。为了用作隔热或隔音产品,粘合的矿物纤维垫通常通过以常规方式将由合适的原料制成的熔体转化为纤维来生产,例如通过纺丝杯工艺或通过级联转子工艺。将纤维吹入成形室中,并且在空气中且仍然热的同时,用粘结剂溶液喷涂,并作为垫或网随机沉积到行进的输送机上。然后将纤维垫转移到固化炉中,在固化炉中将热空气吹过垫以固化粘结剂并将矿物纤维牢固地粘结在一起。
在过去,选择的粘结剂树脂是苯酚-甲醛树脂,其可以经济地生产并且可以在用作粘结剂之前用脲扩链。然而,针对降低或消除甲醛排放的现有和提出的立法已经导致无甲醛粘结剂的开发,例如基于多羧基聚合物和多元醇或多元胺的粘结剂组合物,例如EP-A-583086、EP-A-990727、EP-A-1741726、US-A-5,318,990和US-A-2007/0173588中所公开的。
另一类非苯酚-甲醛粘结剂是脂族和/或芳族酸酐与烷醇胺的加成/消除反应产物,例如在WO 99/36368、WO 01/05725、WO 01/96460、WO 02/06178、WO 2004/007615和WO2006/061249中所公开的。这些粘结剂组合物是水溶性的并且就固化速度和固化密度而言表现出优异的粘合性能。WO 2008/023032公开了该类型的脲改性粘结剂,其提供具有降低的水分吸收的矿棉产品。
由于用于生产这些粘结剂的一些原料是相当昂贵的化学品,因此一直需要提供经济生产的无甲醛粘结剂。
与先前已知的来自矿物纤维的水性粘结剂组合物相关的另一个效果是用于生产这些粘结剂的至少大部分起始材料来自化石燃料。消费者正在倾向于完全或至少部分地由可再生材料生产的产品,因此需要提供至少部分地由可再生材料生产的用于矿棉的粘结剂。
使用矿物纤维产品作为工业设备或管线的隔热体或隔音体的主要问题是腐蚀。因此,隔绝体下腐蚀(CUI)是指由于水或湿气渗透在外部包覆隔绝体下方发生的管线或设备的外部腐蚀。腐蚀的表面大部分被隔绝系统隐藏,并且直到为了检查而移除隔绝体或在金属失效和/或泄漏而导致健康和安全事故的情况下才被观察到。CUI特别是在经历循环温度变化的钢结构(例如石油和天然气工业中的管道)用隔绝体下发生。
腐蚀在水和氧气的存在下发生。如果隔绝体下的设备或管线(例如钢工件)保持干燥,则没有腐蚀问题。然而,保持隔绝体干燥可能是困难的。某种类型的腐蚀可由水溶性氯化物引起或支持。用于矿物纤维的现有技术粘结剂组合物可包含大量的水溶性氯化物。因此,矿物纤维产品本身可能对隔绝部件的腐蚀有贡献。
碳钢隔绝体下的腐蚀风险在50至175℃的温度范围内被认为是高的并且在-20℃至320℃之间的循环温度工作中被认为是极端的。最常见的CUI类型是碳钢的一般和点状腐蚀(如果湿隔绝体与碳钢接触其可能发生),以及奥氏体不锈钢的外部应力腐蚀痕迹(ESCT),其是主要由水溶性氯化物的作用所引起的特定类型的腐蚀。
发明内容
因此,本发明的一个目的是提供一种用于隔绝体的矿物纤维产品,其对隔绝物体的腐蚀性降低,能经济地制备并且使用可再生材料作为起始产品制备用于生产矿物纤维产品的水性粘结剂组合物。
本发明的另一个目的是提供这种矿物纤维产品的用途。
根据本发明的第一方面,提供了一种矿物纤维产品,其包含由固化的粘结剂组合物结合的矿物纤维,未固化的粘结剂组合物包含一种或多种木质素磺酸盐木质素,木质素磺酸盐木质素具有0.03-1.4mmol/g的羧酸基团含量,基于木质素磺酸盐木质素的干重,其中该矿物纤维产品根据EN 13468:2001的水可浸出氯化物含量小于10mg/kg。
根据本发明的第二方面,提供了矿物纤维产品作为隔热体和/或隔音体,特别是非腐蚀性隔热体和/或隔音体的用途,该矿物纤维产品包含由固化的粘结剂组合物结合的矿物纤维,未固化的粘结剂组合物包含一种或多种木质素磺酸盐木质素,木质素磺酸盐木质素具有基于木质素磺酸盐木质素干重的0.03至1.4mmol/g的羧酸基团含量,其中该矿物纤维产品任选地根据EN 13468:2001的水可浸出氯化物含量小于10mg/kg。
根据本发明的第三方面,提供了一种用于制造矿物纤维产品的方法,矿物纤维产品包含由固化的粘结剂组合物结合的矿物纤维,未固化的粘结剂组合物包含一种或多种木质素磺酸盐木质素,基于木质素磺酸盐木质素的干重,木质素磺酸盐木质素具有0.03至1.4mmol/g的羧酸基团含量,其中该矿物纤维产品任选地根据EN 13468:2001的水可浸出氯化物含量小于10mg/kg,该方法包括以下步骤:
a)提供包含一种或多种木质素磺酸盐木质素和水的未固化的水性粘结剂组合物,
b)使矿物纤维与未固化的水性粘结剂组合物接触,和
c)使与矿物纤维接触的粘结剂组合物固化,
其中包含在未固化的水性粘结剂组合物中的至少部分水或全部水是添加的非净化水,其中非净化水优选地选自自来水、雨水、工艺水或其组合。
优选地,木质素磺酸盐木质素具有0.03-1.4mmol/g的羧酸基团含量,基于木质素磺酸盐木质素的干重。
根据本发明的第四方面,提供了一种覆盖有矿物纤维产品作为隔热体和/或隔音体的中空物体,其中该矿物纤维产品包含由固化的粘结剂组合物结合的矿物纤维,未固化的粘结剂组合物包含一种或多种木质素磺酸盐木质素,木质素磺酸盐木质素具有0.03-1.4mmol/g的羧酸基团含量,基于木质素磺酸盐木质素的干重,其中该矿物纤维产品任选地根据EN 13468:2001的水可浸出氯化物含量小于10mg/kg。
本发明人已经发现当基于木质素磺酸盐木质素的粘结剂组合物用于矿物纤维产品时,可以使用矿物纤维产品作为低腐蚀性或甚至非腐蚀性的隔热体和/或隔音体。这种粘结剂组合物具有令人惊讶的低的水可浸出氯化物含量。
具体实施方案
本发明的矿物纤维产品包含由固化的粘结剂组合物结合的矿物纤维,未固化的粘结剂组合物包含一种或多种木质素磺酸盐木质素,基于木质素磺酸盐木质素的干重,木质素磺酸盐木质素具有0.03至1.4mmol/g的羧酸基团含量,其中矿物纤维产品根据EN 13468:2001的水可浸出氯化物含量小于10mg/kg,其中根据EN 13468:2001的水可浸出氯化物含量优选小于6mg/kg。
就本申请而言,根据EN 13468:2001测量矿物纤维产品的水可浸出氯化物含量。标准EN 13468:2001尤其涉及建筑设备和工业装置的隔热产品中痕量水溶性氯化物的测定。该标准规定了用于测定产物的水性提取物中痕量水溶性氯化物的设备和程序。对于细节,参考该标准。
水可浸出氯化物含量以mg氯化物/kg矿物纤维产品给出。参考EN标准中的表1,使用100℃和0.5h用于浸出。样品制备根据EN 13468的7.2.1。根据EN 13468的7.2.2.2进行分析(离子色谱法测定)。
本发明人发现本发明的矿物纤维产品具有令人惊奇的低的水可浸出氯化物含量。当使用非净化水如自来水或工艺水来制备未固化的粘结剂组合物时,这甚至是真实的。如本领域技术人员已知的,非净化水可含有相当大量的氯化物。
不希望受任何特定理论的束缚,本发明人认为即使自来水或工艺水用于制备粘结剂组合物,本发明的矿物纤维产品的低水可浸出氯化物含量也至少部分地基于在基于木质素磺酸盐木质素的粘结剂基质内氯化物离子的捕获。这种捕获阻止了氯化物的浸出使得其不可用于腐蚀活性。
通常,未固化的粘结剂组合物是水性粘结剂组合物。水性粘结剂组合物中包含的水可以是加入的净化水、非净化水或净化水和非净化水的组合。
在优选的实施方案中,未固化的粘结剂组合物是水性粘结剂组合物,其中水性粘结剂组合物中包含的至少部分水或全部水是非净化水,其它部分水(如果有的话)是净化水。这是令人惊讶的,因为在常见的现有技术粘结剂中通常使用净化水来避免相当的氯化物含量。净化水的实例是渗透水、去离子水或蒸馏水并且在下文进一步公开。
净化水通常是经过机械过滤或加工以除去杂质并使其适合使用的水。蒸馏水是净化水的最常见形式,但是近年来,水更频繁地通过其他方法净化,该方法包括电容去离子化、反渗透、碳过滤、微滤、超滤、紫外氧化或电去离子。优选的是,在未固化的粘结剂组合物中使用的纯化水具有小于10mg/L、优选小于5mg/L的氯化物含量。
合适非净化水的实例是自来水、雨水、工艺水或其组合。自来水和雨水的氯化物含量通常在10-200mg/L的范围内。工艺水的氯化物含量通常在25-200mg/L氯化物的范围内。优选的是,在未固化的粘结剂组合物中使用的未净化水可以具有至少10mg/L的氯化物含量,例如10-200mg/L的氯化物含量。
加入的非净化水的比例可以在0-100wt%,优选30-100wt%,最优选50-100wt%的范围内,基于在未固化粘结剂组合物中包含的水的总重量,其它比例(如果有的话)是净化水。
在生产厂中,该粘结剂组合物通常以浓缩形式生产,即将水含量保持较低。在递送之后,通过在矿物纤维生产现场添加水将浓缩的粘结剂组合物稀释至合适的粘度。使稀释的粘结剂组合物与矿物纤维接触并固化以产生矿物纤维制品。本发明的益处是可以使用非净化水如自来水、雨水或工艺水来稀释浓缩的粘结剂组合物,并且仍然获得水可浸出氯化物含量低的产品。

用于制备本发明矿物纤维产品的未固化粘结剂组合物包含一种或多种木质素磺酸盐木质素作为组分(i)。
组分(i)
组分(i)是一种或多种木质素磺酸盐木质素的形式,其羧酸基团含量为0.03-2.0mmol/g,例如0.03-1.4mmol/g,例如0.075-2.0mmol/g,例如0.075-1.4mmol/g,基于木质素磺酸盐木质素的干重。
木质素、纤维素和半纤维素是植物细胞壁中的三种主要有机化合物。木质素可以被认为是将纤维素纤维保持在一起的胶。木质素含有亲水性和疏水性基团两者。它是世界上第二丰富的天然聚合物,仅次于纤维素,并且估计占生物质中所含总碳的多达20-30%,其在全球超过10亿吨。
木质素磺酸盐方法引入大量的磺酸盐基团,使木质素可溶于水,但也可溶于酸性水溶液。木质素磺酸盐具有高达8%的作为磺酸盐的硫,而硫酸盐木质素具有1-2%的硫,主要与木质素键合。木质素磺酸盐的分子量为15.000-50.000g/mol。木质素的典型疏水性核与大量离子化磺酸根基团一起使该木质素作为表面活性剂具有吸引力,并且其通常可用于分散水泥等。
为了生产基于木质素的增值产品,应首先从生物质中分离木质素,为此可以采用几种方法。硫酸盐和亚硫酸盐制浆工艺因其从木材中有效分离木质素而闻名,因此在世界范围内使用。借助于NaOH和Na2S将硫酸盐木质素与木材分离。来自亚硫酸盐制浆过程的木质素被称为木质素磺酸盐,并且通过使用亚硫酸和/或含有镁、钙、钠或铵的亚硫酸盐在不同pH水平下生产。目前,木质素磺酸盐占商业木质素总市场的90%,并且全球木质素磺酸盐的年度总产量约为180万吨。木质素磺酸盐通常具有丰富的磺酸基,因此具有比硫酸盐木质素更高的硫量。由于磺化基团的存在,木质素磺酸盐是带阴离子电荷的并且是水溶性的。木质素磺酸盐的分子量(Mw)可以类似于或大于硫酸盐木质素的分子量。由于其独特的性质,木质素磺酸盐具有广泛的用途,例如动物饲料、杀虫剂、表面活性剂、石油钻井中的添加剂、胶体悬浮液中的稳定剂和作为混凝土掺合料中的增塑剂。然而,大多数新的纸浆厂采用硫酸盐技术进行纸浆生产,因此,硫酸盐木质素更容易用于增值生产。
然而,木质素磺酸盐和硫酸盐木质素具有来自不同分离方法的不同性质,因此官能团分布不同。木质素磺酸盐中高水平的磺酸基团,通常每四个C9单元至少一个,使得木质素磺酸盐在水中的所有pH水平下都带强电荷。这种丰富的可电离官能团可以解释与其他工艺木质素相比的大多数差异。与硫酸盐木质素相比,更高的电荷密度允许更易溶于水以及在溶液中固体含量更高。此外,出于相同的原因,在相同的固体含量下,与硫酸盐木质素相比,木质素磺酸盐将具有更低的溶液粘度,这可以促进处理和加工。木质素磺酸盐的常用模型结构如图1所示。

实施例
在以下实施例中,制备落入本发明定义的几种粘结剂,并与现有技术的粘结剂进行比较。
木质素磺酸盐由Borregaard,Norway和Lignotech,Florida提供,为固体含量约为50%的液体。Primid XL552由EMS-CHEMIE AG提供。PEG 200由Sigma-Aldrich提供,为简单起见假定为无水,并原样使用。硅烷(Momentive VS-142 40%活性)由Momentive提供且为简单起见按100%计算。硅树脂BS 1052由Wacker Chemie AG提供。NH4OH 24.7%由Univar提供并以提供的形式使用。
分别测定根据本发明的粘结剂和根据现有技术的粘结剂的以下性质:
矿物纤维产品的水可浸出氯化物含量的测定
矿物纤维产品的水可浸出氯化物含量根据EN 13468:2001测量。该标准规定了用于测定产品的水性提取物中痕量水溶性氯化物的设备和程序。对其进行引用。水可浸出氯化物含量以mg氯化物/kg矿物纤维产品给出。
矿物纤维制品烧失量(LOI)的测定
有机材料的量(烧失量)被确定为通过烧掉有机材料获得的试样的重量损失。这按照EN 13820中的规定来完成。粘结剂含量作为LOI。粘结剂包括油和其它粘结剂添加剂(如果存在的话)。
粘结剂干燥固体物质的测定
固化后粘结剂的含量称为“粘结剂固体”。
从石棉上切下圆盘形石棉样品(直径:5cm;高度1cm)并在580℃下热处理至少30分钟以除去所有有机物。通过将粘结剂混合物的样品(约2g)分布到锡箔容器中经热处理的石棉圆盘上来测量粘结剂混合物的固体。在添加粘结剂混合物之前和之后立即称重含有石棉圆盘的锡箔容器的重量。在锡箔容器中制备两个这样的粘结剂混合物负载的石棉圆盘,然后将它们在200℃下加热1小时。在冷却并在室温下储存10分钟后,称重样品并将粘结剂固体计算为两个结果的平均值。
除非另有说明,否则以下试剂按原样使用:
PEG 200:由Sigma-Aldrich提供,为简单起见假定是无水的并按原样使用。
Primid XL552:羟烷基酰胺交联剂,由EMS-CHEMIE AG提供
粘结剂实施例,参比粘结剂A3(用脲和右旋糖改性的苯酚-甲醛树脂,PUF-甲阶酚醛树脂)
该粘结剂是用脲改性的苯酚-甲醛树脂、PUF-甲阶酚醛树脂。
在46%氢氧化钾水溶液(25.5g)的存在下,先以约1℃/分钟的速率加热,然后在84℃反应温度下使37%甲醛水溶液(606g)和苯酚(189g)反应来制备苯酚-甲醛树脂。在84℃下继续反应直至树脂的耐酸性为4,大部分苯酚被转化,然后加入脲(241g),冷却混合物。
耐酸性(AT)表示给定体积的粘结剂可以用酸稀释而混合物不变混浊(粘结剂沉淀)的次数。硫酸用于确定粘结剂生产中的停止标准,并且低于4的耐酸性表明粘结剂反应结束。
为了测量AT,用1L离子交换水稀释2.5ml浓硫酸(>99%)制备滴定剂。然后在室温下用该滴定剂滴定5mL待研究的粘结剂,同时通过手动摇动保持粘结剂运动;如果优选,使用磁力搅拌器和磁棒。继续滴定直到粘结剂中出现轻微的云状物,当摇动粘结剂时该云状物不会消失。
耐酸性(AT)通过将用于滴定的酸的量(mL)除以样品的量(mL)来计算:
AT=(所用滴定体积(mL))/(样品体积(mL))
使用所获得的脲改性的酚醛树脂,通过加入25%氨水(90mL)和硫酸铵(13.2g),然后加入水(1300g)来制备粘结剂。

用于参比粘结剂A3的稀释水是工艺水。
粘结剂实施例A1和A2:

然后测量粘结剂固体(21.2%)。对于机械强度研究(15%粘结剂固体溶液,粘结剂固体的0.5%硅烷),用水(0.403kg/kg粘结剂混合物)和10%硅烷水溶液(0.011kg/kg粘结剂混合物,Moment ive VS-142)稀释粘结剂混合物。最终的粘结剂混合物具有pH=7.9并用于生产隔绝产品。

实施例2
将1910.0kg木质素磺酸铵置于混合容器中,向其中加入22升NH4OH(24.7%)并搅拌。然后,加入395kg的Primid XL552溶液(预制的31wt%水溶液)和112kg的PEG 200(100%固体)并混合,然后加入34kg硅烷(Momentive VS-142 40%活性,10%水溶液)。
