Description
本发明涉及可涂饰的多层墙壁覆盖层(revêtementmuralmulti-couchesàpeindre),所述覆盖层(revêtement)包含玻璃织物(textiledeverre),该玻璃织物粘接到基于具有多叶形横截面(sectionmultilobée)的纤维的无纺布上,并且即使在涂饰状态下也具有高吸音能力。其还涉及制造此类覆盖层的方法及其用于改善房间或建筑的声学舒适性的用途。
“声学舒适性”的概念,类似一般的舒适的观念,是相对主观的概念。但是,通常认为可以通过以下因素定义良好的声学舒适性:声音(如人声与音乐)的良好清晰度、既不太短以避免声音沉闷的印象又不太长以避免残余回声太过明显的混响时间、以及不存在具有过高声功率的声音。声学舒适性品质主要通过使用固定到例如墙壁和/或地板上的吸音材料令声音衰减来控制。
重要的是区分声学舒适性与隔音性。当声音遇到障碍物,如建筑物的墙壁(paroi)时,一部分入射的声能被反射,另一部分被吸收,第三部分通过障碍物传输。隔音的目的在于减少声音的传输,而改善声学舒适性的目的在于减少和优化被反射的声音成分。
两种最常用于评价声学舒适性品质的参数是混响时间和吸声系数,也称为AlphaSabine指数(αw)。后者定义为被给定材料吸收的声能对入射的声能的比(Ea/Ei)。通过根据标准NFENISO354(在混响室中的吸音测量)进行的扩散场测量测定AlphaSabine指数,并根据标准NFENISO11654(用于建筑物的吸收体——吸音的评价)计算。
由扩散场中获得的吸声系数,在标准NFENISO11654中定义、描述了各种类型的性能。
通常,具有所给多孔或纤维结构以及化学性质的吸音材料或覆盖层在其厚的时候更有效地吸收声音,换句话说,其αw指数随厚度而提高。但是出于容易理解的原因,出售具有过度厚度的墙壁覆盖层是不合意的。它们将需要大的储存与运输能力,并难以被个人安装。过度的厚度,例如超过大约1厘米,还会产生审美问题,特别是在个人住宅领域。
吸音墙壁覆盖层的另一问题是它们的表面外观。通常用具有高度透气并因此也高度可透声音的多孔表面层的涂层获得最佳吸音性质。但是,从审美的观点来看,此类多孔表面层并不总是令人满意,特别是通常不希望涂饰它们,当用涂料层(couchedepeinture)覆盖它们时,其吸音能力急剧降低。
本发明的目的是提出一种可涂饰的墙壁覆盖层,该覆盖层即使在涂饰状态下也具有使其能够作为根据标准NFENISO11654的吸音覆盖层至少分类到类别E(αw=0.15至0.25)或甚至类别D(αw=0.30至0.55)的吸声系数,并且其厚度在涂饰前不超过6毫米。本发明的墙壁覆盖层由此结合了良好的吸音性质和尽可能接近商业可涂饰墙壁覆盖层,如基于玻璃纤维布的覆盖层的令人满意的审美外观。
一定数量的文献描述了隔音多层墙壁覆盖层。
由此,申请CH650196描述了包含开放孔隙泡沫载体和纺织品表面层的多层墙壁覆盖层,所述泡沫载体含有填料和阻燃组分,所述纺织品表面层例如由聚酯制成。插在这两层之间的是穿孔铝箔,意在改善该覆盖层的耐火性。
申请FR2672908描述了一种多层墙壁覆盖层,其中通过热封连续膜将织物层粘接到发泡载体上,该发泡载体随即通过第二热封连续膜粘接到底层上。
类似地,FR0061369公开了一种墙壁覆盖层,其中合成聚合物纺织品通过由聚乙烯制成的热封连续膜粘接到开放孔隙泡沫片材上。
EP0271681公开了一种吸音墙壁覆盖层,其中透气纸张或纺织品层粘接到间隔层结构上,例如纺织品、穿孔板或塑料格栅。覆盖织物的间隔层结构随后粘接到吸音多孔结构上。
专利US5681408描述了吸音多层墙壁覆盖层,其中两个相对松散的纺织品通过聚乙烯膜彼此粘接。
专利US4283457描述了一种吸音墙壁覆盖层,其中由玻璃纤维制成的针刺毡通过反应性粘合剂粘接到开放孔隙聚氨酯泡沫上。该材料描述为具有良好的吸音性质,但是这些性质在非常厚的覆盖层上获得,该覆盖层的厚度为1至2厘米并处于未涂饰状态。构成这种覆盖层的表面层的由玻璃纤维制成的针刺毡本身不适于或本身不能很好地适于涂施丙烯酸或醇酸涂料。
这些文献均未能公开即使在低厚度和涂饰状态下也具有允许分类为根据标准NFENISO11654的吸引体的大于或等于0.2的吸声系数(αw)的基于玻璃织物的覆盖层。
在对基于粘接到无纺布载体上的玻璃织物的涂饰或未涂饰的墙壁覆盖层进行的大量扩散场吸音试验后,本申请人已经成功地凸显以下三种趋势:
将与涂料或与房间大气接触的玻璃织物必须具有一定范围内的透气性。该透气性必须足够以使得声音能够穿透到下方的泡沫层中,但是不应超过一个值,超出该值,该材料将在涂饰状态下具有不令人满意的外观。
该无纺布载体必须主要由具有多叶形横截面的纤维组成。该纤维的多叶形横截面实际上在相同密度下提高了纤维壁与空气之间的界面的面积,并且在该界面水平穿过该玻璃织物的声音被吸收。声音可达到的界面的尺寸越大,最终的多层产品的吸声系数将越好。
将玻璃织物粘合到无纺布载体上的粘合剂层不能堵塞载体的所有表面孔隙,换言之,必须令其中穿过表面层的声音可以穿透到无纺布中以便在其中被吸收的微观区自由。但是,粘合剂的量必须足以使玻璃织物能够良好地粘合到该无纺布载体上,否则吸声系数将不合意地降低。
申请人由此观察到,通过优化上面的三个参数(表面处的玻璃织物的透气性,粘合剂层的结构和无纺布载体的纤维的多叶形结构),可能获得在涂饰状态下具有大于或等于0.25的根据NFENISO354和NFENISO11654测定的αw指数的薄的墙壁覆盖层。
因此,本发明的一个主题是一种多层结构,具有3.5至6毫米的总厚度,包含:
(a)由基于具有多叶形横截面的有机纤维的无纺布制成的载体层,
(b)由玻璃织物形成的表面层,具有105N.s.m-4至106N.s.m-4、优选5×105N.s.m-4至8.5×105N.s.m-4、特别是7×105N.s.m-4至8×105N.s.m-4的根据标准ISO9053测得的静态空气流动阻力,
(c)在载体层(a)与表面层(b)之间的界面处的不连续的粘合剂层,所述粘合剂层具有17至60g/m2、优选20至40g/m2、特别21至30g/m2且理想地为22至27g/m2的表面密度(massesurfacique)。
在本发明中,三个层(a)、(b)和(c)是彼此邻接的,换句话说,粘合剂层(c)将表面层(b)直接粘合到无纺布载体层(a)上,在层(a)和(b)之间不存在任何其它层(例如铝箔、加强层或间隔层)。
上面的静态空气流动阻力值是对未涂饰状态下且当然在粘接到无纺布载体层上之前的玻璃织物测得的那些。
该无纺布载体形成层(a)具有以下显著特征:至少主要地、优选至少80重量%由具有多叶形横截面的纤维(下文中也称为多叶形纤维)构成。这些纤维是至少部分由一种或多种热塑性的、通常为合成的聚合物组成的有机纤维。
作为构成层(a)的多叶形纤维的合成聚合物的实例,可以提到聚烯烃,如聚丙烯和聚乙烯,聚酰胺均聚物或共聚物,如尼龙6/6、6/9、6/10、6/12、10、11和12,聚酰亚胺,聚酯如聚(对苯二甲酸亚烷基酯)和聚(萘二甲酸亚烷基酯),聚乳酸,聚羟基链烷酸酯,聚乙烯醇,乙烯/乙烯醇(EVA)共聚物,聚丙烯酸酯,聚己内酯,乙烯/丙烯酸共聚物,聚丙烯酸,聚苯乙烯,聚(四氟乙烯),聚氨酯或其组合。
用于本发明的多叶形纤维还还可以含有一定比例,优选小于30%的非热塑性材料,如粘胶纤维、人造丝、莱塞尔纤维、棉、木浆或甚至玻璃纤维。
该多叶形纤维可以由两种或超过两种的不同相形成,例如由叶片连接到其上的中心相(芯)形成,这些叶片可能由不同的聚合物材料形成。
它们尤其可以是通过溶胶-凝胶路线制备的纤维或通过熔融路线,例如通过挤出获得的玻璃-聚合物混合纤维(hybridfiber)。
构成该载体层(a)的具有多叶形横截面的有机纤维可以是单丝纤维或由数条单丝组成的多丝纤维。它们可以是连续的或不连续的,并优选具有1至25dtex、特别为3至15dtex且理想地为5至12dtex的平均线密度。该纤维的长度有利地为0.5至15厘米,优选1至10厘米且特别为2至8厘米。
该多叶形纤维优选是具有三叶、四叶或五叶形横截面的纤维。
叶片的形状没有特殊限制。其可以是浑圆的或具有边缘。该叶片可以具有复杂形状,例如T形或Y形,或各叶片可以具有几个分支。
已知对于多叶形纤维定义修饰比(rapportdemodification),其符合该纤维横截面的外接圆直径(R)对内切圆的直径(r)的比。该R/r比优选为2至7,特别为3至6。
由多叶形纤维形成的载体层(a)在原则上可以通过制造无纺织物的任何技术获得,例如通过针刺法或纺粘法(spunbonding)。
其优选具有200至800g/m2、更优选250至500g/m2且特别为300至400g/m2的表面密度。
可用于本发明的多叶形纤维及其制造方法是已知的,并描述在例如US2006/0012072、US6815383、WO03/105982、EP0595157、EP0860521、EP0201812和EP2272999中。
如引言中已经解释过的那样,在本发明中基本的是在层(a)和(b)之间的界面处的粘合剂层不是例如在FR2672908、US5681408或FR0061369中通过插入粘合剂膜所形成的连续层。
粘合剂层(c)必须将玻璃织物(b)牢固地粘接到载体(a)上,同时保持最大数量的位于层(a)与(b)之间界面处的孔隙开放。不幸的是极难或甚至不可能精确地量化成品中封闭或开放的表面孔隙的比例。
为了达到令人满意的声学结果,必须保持每单位表面一定的涂施量并且不以连续的膜或层的形式沉积粘合剂。必须沉积该粘合剂以便在宏观尺度上相对均匀地覆盖整个界面范围,但是应保证在微观尺度上仅有某些区域覆盖有粘合剂,而其它区域保持空的。例如可以使用环境温度下为固体的网络或格栅形式的热熔粘合剂(hotmeltadhesive)进行此类“不连续”涂施,在高于该粘合剂的软化点或熔点的温度对该组件施以压力下的加热之前将所述热熔粘合剂插在泡沫载体与玻璃织物之间。还可能设想以热熔粘合剂粉末形式将粘合剂施加到无纺布载体(a)上或施加到玻璃织物(b)上,随后施加第二层(b)或(a)并在压力下加热。
热熔粘合剂的化学性质并非本发明的决定性因素,可能使用基于聚氨酯、共聚酰胺(coPA)或PTE的共聚物(coPET),如Protechnic公司提供的产品Texiron9D8的常规热熔粘合剂。
最后,该粘合剂不一定是热熔粘合剂,但可以是例如通过印刷施加到被粘接的两组件之一上的反应性或热固性粘合剂的液体组合物,并确保该粘合剂组合物不会形成连续的膜或层。
但是,只有遵守上面规定的涂施量,包括17至60g/m2、优选20至40g/m2、特别是21至30g/m2且理想地为22至27g/m2,上述“不连续”模式的涂施才能给出良好的声学结果。事实上,如果施加的粘合剂量显著大于60g/m2,该热熔粘合剂存在在熔融时展开直到形成连续层的风险,所述连续层堵塞载体泡沫的表面孔隙,这是必须绝对避免的。相反,如果施加量显著低于17g/m2,在泡沫/玻璃织物界面处的粘合剂强度存在不足的风险,并且申请人观察到,成品由此具有大约0.1至0.15的相当差的吸收系数。
当该粘合剂层(c)由热熔粘合剂形成时,后者的软化点优选低于形成该载体层(a)的多叶形纤维的热塑性聚合物的软化点至少10℃,特别为至少15℃且理想地为至少20℃。这是因为必须防止这种载体层的结构在不益于粘合的热与压力(lachaleuretdelapressiondecontre-collage)的影响下不利地改变。
当遵守有关涂施方法与涂施量的上述所有教导时,成品中的粘合剂层(c)由在层(a)与(b)之间的整个界面上均匀延伸的点和/或线的网络组成。形容词“均匀”在这里具有在宏观尺度上均匀的含义,并包括在微观尺度上的有序和随机的图案。
构成表面层(b)的玻璃织物可以是玻璃布(也就是说由经纱和纬纱组成的纺成织物)或网辐(即无纺布)。还可能设想两者的组合,例如由纺成结构增强的无纺布。但是,本发明不包括如通过针刺法获得的具有非常松散结构的玻璃毡的玻璃织物(textiledeverre)。此类纺织品,当它们具有令人满意的机械强度时,特别具有过大的厚度,并且首先,它们本身通常均不适于涂施涂料。
该玻璃织物优选是玻璃布(toiledeverre),也就是说获自由许多玻璃长丝(或股线)组成的玻璃纱线或这些纱线的衍生物(尤其是粗纱形式的这些股线的组件)的纺成织物。
玻璃布或网辐可以任选含有相对有限比例,通常小于20重量%、优选小于10重量%的由有机材料组成的纤维。这些其它纤维可以是天然纤维如丝纤维、羊毛纤维、木纤维、纤维素纤维或棉纤维;合成或人造纤维如粘胶纤维或人造丝纤维、聚乙烯纤维、聚丙烯纤维、聚对苯二甲酸乙二醇酯纤维、聚苯乙烯纤维、聚甲基丙烯酸甲酯纤维、聚酰胺纤维、聚氯乙烯纤维、聚丙烯腈纤维、聚乙酸乙烯酯纤维、聚乙烯醇纤维、聚酯纤维、聚四氟乙烯纤维和芳纶纤维;金属纤维,例如银纤维、铜纤维或钢纤维;碳纤维;矿物纤维,例如玄武岩纤维、二氧化硅纤维、氧化铝纤维或陶瓷纤维。
混入纱线组成(constitution)中的玻璃可以具有任何类型,例如E、C、R或AR(耐碱)类型。E型玻璃特别是优选的。
构成该纱线的玻璃长丝的直径可以在很大程度上变化,例如5至30μm。长丝的线密度为30至1500tex。
有利地,该玻璃布包含作为经纱的合股玻璃纱(纺织纱线)和作为纬纱的已经经受旨在分离玻璃长丝以令其蓬松(“蓬松化”纱线)的处理的无捻玻璃纱。该经纱与纬纱的线密度优选为50至500tex之间变化。
常规上,用施胶组合物涂布待涂饰的布或网辐,所述施胶组合物保持该纱线并赋予它们合适的刚性以使得能够是适当地进行在最终载体上的安装。
本发明中使用的玻璃织物在本领域是已知的,并可以在市场上获得,例如以Novelio为名获自Adfors公司。它们优选具有80至450g/m2、特别是100至300g/m2且更优选为150至250g/m2的表面密度。
除了上述三个层(a)、(b)和(c)之外,本发明的多层结构可以包含第四层,在下文中称为底层(d),优选其是水蒸气可透的,并粘接到与表面层(b)接触的面相反的载体层(a)的表面上。
该层可以是例如塑料膜、纸板、多孔金属膜、织造织物、非织造织物或其组合。
该层主要是为了便于在施加到其声学舒适性有待改善的房屋墙壁上之前该多层结构的涂胶(encollage)。该底层(d)当然可以被预涂布。
最后,本发明的多层结构可以包含第五层,在下文中称为上层(sur-couche)(e),由施加到表面层(b)上的涂料层构成。
该涂料可以在将该结构粘接到墙壁结构上之前施加,或者可以仅在粘接到墙壁上之后涂饰该多层结构。
涂料上层(sur-couchedepeinture)(e)可以是通常用于装饰生活空间的任何涂料。其可以是水基丙烯酸涂料或醇酸涂料。最终的涂料层可以是微孔的或不是。其通常以小于600g/m2的涂布重量、优选以50至500g/m2的比率且特别以100至350m2/g的比率施加。
如引言中解释的那样,选择各个层的材料能够获得具有在涂饰状态下足以使其分类为根据标准NFENISO11654的吸音覆盖层(类别D或E)的吸声系数的墙壁覆盖层。可以对小的厚度获得该分类。本发明的多层结构因此具有3.5至6mm、优选4.0至5.5mm的总厚度。
本发明的多层结构可以根据非常类似于已知方法的层压方法并在通常用于制造墙壁覆盖层的现有设备上制造。
在一种此类制造方法(其也是本发明的主题)中,按顺序叠加多叶形纤维制成的无纺布、热熔粘合剂的网辐以及玻璃织物,随后将包含至少三个层的由此形成的结构施以至少等于该热熔粘合剂的软化点的温度,优选施加压力,例如通过压延。
使用热熔网辐的一种可能的替代方案是向多叶形纤维制成的无纺布或该玻璃织物的一个面上施加粉末或液体粘合剂组合物。可以例如通过印刷按照有序图案(格栅、等距离点的网络)进行该施加,或者例如通过施加粉末或喷施液体粘合剂组合物按照随图案进行该施加。在施加粘合剂组合物后,令多叶形纤维制成的无纺布与该玻璃织物接触,优选在压力和加热下,以便将该玻璃织物牢固地粘接到多叶形纤维制成的无纺布上。
本发明的最终主题是如上所述的多层结构用于改善房屋或建筑物的声学舒适性的用途。用于改善声学舒适性的方法包括优选通过粘接将本发明的多层结构施加到所述房屋或所述建筑物的一个或多个内表面上,特别是施加到墙壁上。
实施例
以4.5毫米的厚度和300g/m2的表面密度通过针刺法制造由FIT公司所提供的DeepGroove多叶形纤维(4-DG?,6dpf×1.5",由PET制得)制得的莫利通双面绒。
为了比较,制造一种无纺布,其基于具有3.3dtex的线密度的非多叶形纤维,所述非多叶形纤维基于人造丝/聚丙烯(90/10重量比)。这种对比无纺布具有与基于DeepGroove纤维的无纺布相同的表面密度,即等于300g/m2的表面密度,以及4.4毫米的厚度。
将具有220g/m2的表面密度和7.7×105N.s.m-4的静态空气流动阻力的可涂饰的玻璃纤维布层压到各莫利通双面绒上。使用热熔粘合剂的网辐进行层压,所述热熔粘合剂网辐由双组分纤维构成,所述双组分具有聚对苯二甲酸乙二醇酯(PET)芯和coPET共聚物皮,该皮具有低于由PET均聚物制得的中心部分的软化点。热熔粘合剂的网辐具有25g/m2的表面密度。这三个层一个接一个地叠加,并且该组件通过在大约0.5巴的压延压力下在大约90℃的温度加热来粘接。获得的三层结构具有5毫米的总厚度。随后使用乙烯基粘合剂(OvalitUltra,来自Henkel公司)将其粘接到BA13石膏板上,并用缎纹丙烯酸涂料(150g/m2)涂饰。10.80m2的表面由此用于在混响室中的试验(NFENISO354)。
根据NFENISO11654计算的该吸声系数对于使用基于多叶形纤维的载体层的本发明的样品为0.25,对于使用基于非多叶形人造丝/聚丙烯纤维的无纺布的对比覆盖层仅为0.15。
