Abstract

本发明涉及一种衬垫，其包括反射红外线的层。所述反射层是金属层，其上涂覆了保护层，所述保护层包含塑料，其中加入了无定形SiO2，用来防止腐蚀。

Description

衬垫
本发明涉及衬垫薄膜[底垫]。 
底垫是层状的建筑构件，特别是对于斜屋顶，该建筑构件设置在排水屋面覆盖物下方。它们主要用来将被屋顶下方的风吹来雪或雨向下排走。通常在所述底垫上方提供顺水条或者其它的隔离装置。 
底垫除了能够以机械作用驱走雪和雨以外，还具有另外的功能。所述底垫可以设计成能够进行水蒸气扩散的形式,通过其Sd值[水蒸气扩散当量空气层厚度]调节屋顶内部和环境之间的水蒸气传输。另一个功能包括反射热量或者红外辐射。由此使得阁楼在夏季不会被过份地加热，而且在冬季可以减少热量损失。 
EP 1311387 B1中揭示了在建筑领域使用热反射性箔绝热材料,特别是用作底垫。所述热反射性箔绝热材料包含基底聚乙烯膜，在其两个面上气相沉积金属化的层。在这些金属化的层上施涂了保护清漆。通过使用此保护清漆，防止金属化层受到腐蚀。所述保护清漆是基于用异氰酸酯固化的聚氨酯的双组分清漆。 
在EP 1184482 B1中进一步揭示了一种用来制造可渗透水蒸气、防水的热反射性片状复合材料的方法。所述复合材料包括连续的金属层，以及无孔、可渗透水蒸气并且防水的亲水性合成膜。其中所述的膜首先在氧气中或者包含氧气的空气中，通过等离子体处理进行预先清洁。然后在其上施加厚度为10-200纳米的金属层,然后在其上施涂基于交联的聚氨酯的保护层。 
还已知其它的糊料，例如参见DE 199 17 228 B4，该糊料包含消光剂以及/或者结构化添加剂，其包括5-30重量%的一种或多种(甲基)丙烯酸酯共聚物以及/或者一种或多种聚酯,15-45重量%的一种或多种消光剂和/或结构化剂(structuring agent)，以及30-65重量%的一种或多种有机溶剂。可以加入交联剂和分散剂、流变剂、催化剂、以及任选的其它添加剂和辅助 剂。可以通过加入常规的触变剂，使得所述(甲基)丙烯酸酯树脂和聚酯树脂触变。 
在DE19950284A1中还揭示了能够用可见光固化的组合物,其包含2-99重量%的一种化合物，该化合物包含丙烯酸酯基和/或甲基丙烯酸酯基和/或乙烯基和/或环氧基和/或氧杂环丁烷基和/或丙烯酰基-环氧基-低聚物基团和/或基于可聚合聚硅氧烷的树脂化合物。所述组合物还包含至少一种引发剂、至少一种共引发剂以及一种或多种改性剂，例如填料、染料、颜料、流动促进剂、触变剂、聚合物增稠剂、氧化添加剂、稳定剂和延迟剂。 
US2006/0040091A1中还揭示了一种复合金属化的箔,其包括可渗透水蒸气的层，所述层包括第一表面和第二表面，所述层包括至少一种机织结构或无纺结构。在第一表面上施涂厚度约为15-200纳米的金属层,在此金属层上又施涂有有机涂层，所述有机涂层源自有机聚合物、有机低聚物、或其组合。该有机涂层作为保护清漆层，其厚度为0.2-2.5微米。但是,发现此等厚度的保护清漆层无法确保包括机织结构的反射层具有持久的耐腐蚀性。 
因此，本发明所解决的问题是提供了一种能反射热量的底垫，该底垫可以使得水蒸气从中扩散,由此确保实现反射层的持久保护，但是又具有良好的水蒸气渗透性。 
通过如下技术方案解决了这个问题：即一种底垫(10)，其包括至少一个允许水蒸气扩散的层(12,14,16),位于所述水蒸气扩散层(16)上的金属层(20)，以及位于所述金属层(20)上的保护层(22),其特征在于，所述保护层(22)包含无定形SiO2，所述无定形SiO2占干燥的保护层(22)的10-50重量%。 
因此本发明涉及一种底垫，其包括红外线反射层。为了避免腐蚀，在该作为金属层的反射层上涂覆了保护层，所述保护层包含合成材料，加入了无定形SiO2。 
在最简单的情况下，所述底垫由三个层组成,即至少一个允许水蒸气扩散的层,一个热反射金属层，以及施涂在所述金属层上的一个保护层。在本发明中，所述水蒸气扩散层可以是纺粘织物、机织织物或有机聚合物材料的膜。由于它们的结构，纺粘织物是机织织物，允许水蒸气扩散,而所述膜必需是具有微型穿孔的或者多微孔的，以便使得水蒸气扩散。所述热反射金属层优选是在真空条件下沉积在所述水蒸气扩散层上的。但是，在所述水蒸气扩散层中,未形成连续金属层，这是因为在纺粘织物中具有较大的孔，所以纺粘织物中的水蒸气扩散层是不连续的,在膜中，在微孔或微小孔洞的附近，其是不连续的。所述金属优选是纯铝或铝合金。为了避免发生腐蚀,为金属层涂覆保护层，保护层包含合成材料，其中加入了无定形SiO2。 
施涂在水蒸气扩散层上的常规保护清漆能够显著地减小其水蒸气渗透性。在本发明中显著地减小了这种效果，从而可以在保护层上添加无定形SiO2。由此改性的保护层能够长久地保护金属层使其免于发生腐蚀和机械磨损，同时能够确保水蒸气扩散层保持高的水蒸气渗透性。造成这些效果的原因可能在于,例如相对于纯的丙烯酸酯分散体，用无定形SiO2改性的丙烯酸酯分散体的可流动性提高。例如，如果将金属层施涂在具有粘合结构的水蒸气扩散层上，然后涂覆改性的丙烯酸酯分散体,则所述改性的丙烯酸酯分散体会流入所述金属化的粘合的织物的孔中，润湿纤丝，例如无尽的化学纤维。由于纯的丙烯酸酯分散体具有低的可流动性,纯的丙烯酸酯渗入孔内、包围纤丝的能力较差。相反,纯的丙烯酸酯分散体倾向于堵塞孔，使得水蒸气难以扩散。 
在仅有的附图中显示了一个实施方式实施例，在下文中将对其进行描述。 
图中显示了本发明的包括多层结构的底垫10。所述底垫10中包括了第一纺粘织物层12，例如该织物层的单位面积质量为120克/平方米，由聚丙烯制备。在所述第一纺粘织物层12上设置着聚丙烯膜14,该聚丙烯膜14可以是多微孔的或者具有微型穿孔的。由于所述膜14具有微型穿孔或者是多微孔的,该膜14可以进行水蒸气扩散，但是会阻断空气流。所述膜14例如由聚丙烯制成，单位面积质量为30克/平方米,其上施加了第二纺粘织物层16,所述第二纺粘织物层16例如由聚丙烯制成，其单位面积质量为20克/平方米。由于所述两个纺粘织物层12、16的结构，它们能够使得水蒸气扩散。使用热粘合法，由所述第一纺粘织物层12、膜14和第二纺粘织物层16制造了复合体18。在高真空条件下，在所述复合体18的第二纺粘织物 层16上施加了金属层20,优选是铝层。所述施加金属层的步骤可以通过气相沉积或溅射法进行。在所述金属层20上施涂保护层22用来作为耐腐蚀保护,所述保护层包含无定形SiO2。无定形SiO2的一个例子是石英玻璃。在图中所述的实施方式实施例中,所述提供有金属层20的水蒸气扩散层是由第二纺粘织物层16组成的。或者所述水蒸气扩散层也可以由膜14形成。在此情况下，将保护层22施加于膜14之上。 
上述复合体仅仅表示一些可以考虑的实施方式中的一种。也可以采用更简单的结构体系,其中不是将独立的层热粘合在一起，而是互相粘结起来。单层粘合织物可以进行扩散但是它们是不透风的。与之相反，由多微孔箔和粘合的织物组成的双层复合体是不透风而且可以进行扩散的。但是，通常多微孔层对紫外光和机械负荷并不是密封的。与之相反，三层结构具有良好的抗紫外性质，具有机械牢固性质，另外还是不透风的。每个层可以具有不同的重量。 
为了证明所述效果，进行了比较测试,结果列于下表(PP=聚丙烯)。 
Figure GDA00002434302600041
在比较测试中测定了耐腐蚀性，测定了用来描述水蒸气渗透性的Sd值。为了进行腐蚀，样品在沸水上方保持15分钟。由此获得腐蚀结果，该结果对应于通常情况下在空气相对湿度100％、温度60℃的情况下三个月的腐蚀情况。然后通过光学检测和评定了腐蚀的程度。根据EN-DIN 12572测定Sd值。 
从上表可以很明显地看出,测试I显示了复合体18的水蒸气渗透性，该复合体18由第一纺粘织物层12(120克/平方米的聚丙烯),膜14(28克/平方米的聚丙烯多微孔膜)以及第二纺粘织物层16(20克/平方米的聚丙烯)组成。由于该复合体18限定了底垫10的水蒸气渗透性,在测试I中，在不施加金属层20和保护层22的情况下进行Sd值的参比测试。这三层12、14、16的Sd值为4厘米。 
在测试II-VII中，对测试I的底垫10另外添加金属层20,该金属层由35纳米厚的铝层组成，各自涂覆不同的保护层22。在测试II-IV中，在底垫10上施涂纯的丙烯酸酯分散体作为保护层22。与之不同的是，在测试V-VII中,保护层22由包含SiO2的丙烯酸酯分散体组成，在测试V和VI中，其中混合了45%的SiO2，在测试VII中，其中混合了60%的SiO2。在本文中，加入的无定形SiO2的百分比表示相对于干燥的保护层22的重量百分比。该测试证明，就抗腐蚀保护性和Sd值来说，包括用无定形SiO2改性的保护清漆22的底垫10具有最佳的性质。 
关于无定形SiO2加入量的限制，参见下文。通过最小量地加入无定形SiO2，保护层22的性质接近纯丙烯酸酯分散体的性质。为了获得可评估的效果，SiO2的加入量必需至少为10％。当SiO2的用量超过60%的时候，越来越难以在金属层20上获得透明的膜状保护层22,这导致底垫10的反射性能迅速降低。实际上无定形SiO2的加入量存在上限，此时反射性能低于热反射底垫所需的最小值。底垫10的反射性能所需的最小值通常为50%。 
实施例1: 
首先，通过热粘合法制造了三层复合体18，其包括：第一聚丙烯纺粘 织物层12，其重量为120克/平方米；多微孔聚丙烯膜14，其重量为30克/平方米；以及第二聚丙烯纺粘织物层16，其单位面积质量为20克/平方米。在高真空条件下，在所述复合体18的第二聚丙烯纺粘织物扩散层16上气相沉积铝金属层20。该金属层的厚度为35-50纳米。 
然后在提供有金属层20的第二聚丙烯纺粘织物层16的顶侧涂覆12克的清漆(固体含量5克)，形成保护层22,所述清漆由70重量份的纯丙烯酸酯的水性分散体(固体含量48%,Tg=15℃)和30重量份的水性氧化硅溶胶(固体含量30%,300平方米/克表面)组成。采用无气喷涂法施涂涂层，在连续干燥器中进行干燥。干燥后的保护层22的清漆包含21%的无定形SiO2。 
实施例2: 
首先通过热粘合法制造三层复合体18，其包括第一聚丙烯纺粘织物层12，其重量为120克/平方米,具有微型穿孔的聚丙烯膜14，其重量为30克/平方米,以及第二聚丙烯纺粘织物层16，其单位面积质量为20克/平方米。在高真空条件下，在复合体18的第二聚丙烯纺粘织物扩散层16上气相沉积金属层20,该金属层20的厚度为60纳米。 
在所述第二聚丙烯纺粘织物层16的顶侧上提供金属层20，然后涂覆27克的清漆(包含10克固体)，形成保护层22。所述清漆由40重量份的纯丙烯酸酯水性分散体(固体含量48%,Tg=15℃)和60重量份的水性氧化硅溶胶(固体含量30%,300平方米/克表面)组成。所述保护层22通过压延机施涂,例如通过辊轧机施涂，所述辊轧机包括互相叠置的辊子，这些辊子沿相反方向旋转,然后在连续干燥器中干燥。保护层22的干燥的清漆包含48%的无定形SiO2。在本文中，无定形SiO2的粒度可以为1000纳米。 
以上列出的材料仅仅作为示例。层12,14,16均仅由聚丙烯组成，因此可以以更简单的方式进行热粘合。所述对预先制造的复合体进行金属化和涂覆的方法仅仅作为示例。还可以首先对复合体的外层进行金属化，然后将其与其它的层相连，最后施加涂层。还可以首先对外层进行金属化，然后施涂清漆，然后再使其与其它的层相连。 
通常金属层不允许发生扩散。但是，在本发明中，在并没有封闭的织物上气相沉积了一个层,而所述沉积的层也没有封闭的表面。因为织物下方 的箔上没有气相沉积的层,因此金属箔中残留着小孔。还可以在已经气相沉积金属之后，为箔提供孔。还可以不使用所列的丙烯酸类树脂，而是使用聚氨酯聚合物作为粘合剂。 
所列的Sd值中，当材料的Sd>0.2米的时候，是根据EN ISO 1931表征，当材料的Sd<0.2米的时候，是根据EN ISO 12572表征。在DIN 4802.3中，也可以找到关于Sd值的参考文献。 
这些值是通过以下效应定义的：通常从较高的室内温度到较低的外界温度之间，会产生蒸气压梯度，这会通过扩散而变得平衡。这种自然扩散会被涂层或阻挡层箔片减缓。用水蒸气扩散流动密度或Sd值来描述对该平衡的阻抗。所述Sd值或者扩散平衡空气层厚度表示水蒸气迁移通过气密性结构部件所需的时间长度。如果该Sd值为例如3米,则表示水蒸气对流通过该气密板材所需的时间长度等于其迁移通过3米厚的空气层所需的时间长度。因此，该结构部件对水蒸气的阻挡作用相当于3米厚的空气层。
