Description

聚合物泡沫
技术领域
本发明涉及含有低含量的高表面积二氧化硅的聚合物泡沫。也描述了热熔融粘合剂泡沫、含有这种泡沫的条带以及它们的制备方法。
发明内容
简言之，在一个方面，本发明提供了一种泡沫，所述泡沫包括聚合物、多个至少部分膨胀的可膨胀聚合物微球和0.3至1.5重量％的表面积为根据ASTM D1993-03(2008)测得的至少300平方米/克的二氧化硅。在一些实施例中，所述泡沫包括至少0.5重量％的所述二氧化硅。在一些实施例中，所述泡沫包括不大于1重量％的所述二氧化硅。

具体实施方式
Gehlsen等人(美国专利No.6,103,152和No.6,797,371)描述了制作聚合物泡沫(包括丙烯酸泡沫)的多种方法。在一些实施例中，所述方法包括利用至少一种可膨胀聚合物微球(“epm”)熔融混合聚合物混料以及将混料通过模具挤出以形成聚合物泡沫。这些泡沫可随后被电子束(“E-beam”)固化。所述泡沫可与一个或多个粘合剂层合并以形成粘合剂制品，例如在泡沫芯的每个主表面上包括一层表皮粘合剂的制品。
虽然这种粘合剂制品已经成功地应用于大范围的应用中，但是本发明人发现将少量高表面积二氧化硅添加到泡沫芯将导致多个关键机械性能的惊人提高，所述机械性能包括断裂伸长率、粘合强度和层间粘合力的一个或多个。
在一些实施例中，本发明提供了一种泡沫，其包括聚合物、多个至少部分膨胀的可膨胀聚合物微球和0.5至1.5重量％的二氧化硅，其BET表面积为至少300平方米/克。
一般来讲，对聚合物的选择不受具体限制。在一些实施例中，可能有利的是，选择适于熔融挤出工艺的聚合物或聚合物的共混物。示例性聚合物包括丙烯酸类聚合物、不溶性丙烯酸酯聚合物、含有紫外线辐射活化基团的弹性体和由非光致聚合型单体制备的聚合物。
在一些实施例中，所述聚合物可包括一种或多种丙烯酸类聚合物，例如丙烯酸酯和甲基丙烯酸酯粘合剂聚合物和共聚物。如本文所用，术语“(甲基)丙烯酸酯”是指丙烯酸酯和/或甲基丙烯酸酯，即(甲基)丙烯酸乙酯是指丙烯酸乙酯和/或(甲基)丙烯酸乙酯。
在一些实施例中，丙烯酸类聚合物包括至少一种非叔烷基醇的丙烯酸酯或甲基丙烯酸酯与可选地至少一种共聚的强化单体的反应产物。在一些实施例中，丙烯酸类聚合物包含至少约70份，在一些实施例中，至少约80份、至少约90份、至少约95份或甚至约100份的至少一种非叔烷基醇的丙烯酸酯或甲基丙烯酸酯。在一些实施例中，丙烯酸类粘合剂聚合物包含不超过约30份，在一些实施例中，不超过约20份、不超过约10份、不超过约5份，甚至不超过约1份的至少一种共聚的强化单体。在一些实施例中，所述丙烯酸类粘合剂组合物不包括共聚的强化单体。
在一些实施例中，非叔烷基醇含有4至20个碳原子。示例性的丙烯酸酯包括丙烯酸异辛酯、丙烯酸-2-乙基己酯、丙烯酸丁酯、丙烯酸异冰片酯以及它们的组合。示例性的甲基丙烯酸酯包括这些丙烯酸酯的甲基丙烯酸酯类似物。
在一些实施例中，共聚的强化单体选自丙烯酸、甲基丙烯酸、2-羧乙基丙烯酸酯、N，N′二甲基丙烯酰胺、N，N′二乙基丙烯酰胺、丁基氨基甲酰乙基丙烯酸酯以及它们的组合。
在一些实施例中，可能有利的是，将至少一种高分子量(甲基)丙烯酸酯聚合物与至少一种低分子量(甲基)丙烯酸酯聚合物合并。
在一些实施例中，所述聚合物可包括嵌段共聚物。在一些实施例中，所述嵌段共聚物包括橡胶态嵌段R和至少一种玻璃态嵌段G。在一些实施例中，嵌段共聚物包含至少三个玻璃态嵌段。在一些实施例中，第一嵌段共聚物包含在三个和五个之间的玻璃态嵌段，包括三个和五个。在一些实施例中，第一嵌段共聚物包括四个玻璃态嵌段。
在一些实施例中，第一嵌段共聚物是多臂嵌段共聚物，其具有通式Qn-Y，其中Q代表多臂嵌段共聚物的臂；n代表臂的数量并且为至少3的整数；并且Y是多官能偶联剂的残基。每个臂Q，独立地具有式R-G，其中G代表玻璃态嵌段；R代表橡胶态嵌段。
一般来讲，橡胶态嵌段表现出具有低于室温的玻璃化转变温度(Tg)。在一些实施例中，橡胶态嵌段的Tg小于约0℃，或甚至小于约-10℃。在一些实施例中，橡胶态嵌段的Tg小于约-40℃，或甚至小于约-60℃。
通常，玻璃态嵌段表现出具有高于室温的Tg。在一些实施例中，玻璃态嵌段的Tg为至少约40℃、至少约60℃、至少约80℃或甚至至少约100℃。
在一些实施例中，橡胶态嵌段包括聚合共轭双烯、聚合共轭双烯的氢化衍生物或它们的组合。在一些实施例中，共轭双烯包含4至12个碳原子。示例性的共轭双烯包括丁二烯、异戊二烯、乙基丁二烯、苯基丁二烯、戊间二烯、戊二烯、己二烯、乙基己二烯和二甲基丁二烯。聚合共轭双烯可单独使用或作为与彼此的共聚物使用。在一些实施例中，共轭双烯选自异戊二烯、丁二烯、乙烯丁二烯共聚物以及它们的组合。
在一些实施例中，至少一个玻璃态嵌段包含聚合的单乙烯基芳族单体。在一些实施例中，三嵌段共聚物的两个玻璃态嵌段包含聚合的单乙烯基芳族单体。在一些实施例中，单乙烯基芳族单体包含8至18个碳原子。示例性的单乙烯基芳族单体包括苯乙烯、乙烯基吡啶、乙烯基甲苯、α-甲基苯乙烯、甲基苯乙烯、二甲基苯乙烯、乙基苯乙烯、二乙基苯乙烯、叔丁基苯乙烯、二正丁基苯乙烯、异丙基苯乙烯、其它烷基化苯乙烯、苯乙烯类似物和苯乙烯同系物。在一些实施例中，单乙烯基芳族单体选自苯乙烯、苯乙烯相容单体或单体共混物以及它们的组合。
如本文所用，“苯乙烯相容单体或单体共混物”指优先与聚苯乙烯相连或与嵌段共聚物的聚苯乙烯末端嵌段缔合的可聚合或共聚的单体或单体的共混物。相容性可产生自：与单体苯乙烯的实际共聚作用；在热熔融或溶剂加工过程中相容单体或共混物或聚合的单体或共混物在聚苯乙烯相中的可溶性；或在加工之后静置时单体或共混物与富含苯乙烯的相畴的缔合。
在本发明的一些多臂嵌段共聚物的通式Qn-Y中，n代表臂的数量并且为至少3的整数，即多臂嵌段共聚物是星形嵌段共聚物。在一些实施例中，n在3-10的范围内。在一些实施例中，n在3-5的范围内。在一些实施例中，n为4。在一些实施例中，n等于6或更大。
在一些实施例中，嵌段共聚物是多模嵌段共聚物。本文所用的术语“多模”是指包括具有至少两个不同分子量的玻璃态嵌段的共聚物。这种嵌段共聚物还可被表征为具有至少一个“高”分子量玻璃态嵌段，和至少一个“低”分子量玻璃态嵌段，其中术语高和低是相对于彼此使用的。在一些实施例中，高分子量玻璃态嵌段的数均分子量(Mn)H相对于低分子量玻璃态嵌段的数均分子量(Mn)L的比率为至少约1.25。
在一些实施例中，(Mn)H的范围在约5,000至约50,000克/摩尔。在一些实施例中，(Mn)H为至少约8,000克/摩尔，在一些实施例中，为至少约10,000克/摩尔。在一些实施例中，(Mn)H不大于约35,000克/摩尔。在一些实施例中，(Mn)L的范围在约1,000至约10,000克/摩尔。在一些实施例中，(Mn)L为至少约2,000克/摩尔，在一些实施例中，为至少约4,000克/摩尔。在一些实施例中，(Mn)L小于约9,000克/摩尔，在一些实施例中，小于约8,000克/摩尔。
在一些实施例中，嵌段共聚物是非对称嵌段共聚物。本文所用的术语“非对称”是指嵌段共聚物的臂不是都一样的。一般来讲，由于玻璃态嵌段的分子量并非都一样，因此多模嵌段共聚物是并非所有多模嵌段共聚物的臂都一样的非对称嵌段共聚物(即，多模非对称嵌段共聚物)。在一些实施例中，本发明的嵌段共聚物是多模非对称嵌段共聚物。在例如美国专利No.5,296,547中描述了制造非对称多模嵌段共聚物的方法。
一般来讲，多官能偶联剂可为任何聚烯基偶联剂或已知具有可与活性聚合物的负碳离子反应以形成连接的聚合物的官能团的其它材料。聚烯基偶联剂可为脂族的、芳族的或杂环的。示例性的脂族聚烯基偶联剂包括聚乙烯基乙炔和聚烷基乙炔、二乙炔、磷酸酯、亚磷酸酯和二甲基丙烯酸酯(例如二甲基丙烯酸酯乙二醇酯)。示例性的芳族聚烯基偶联剂包括聚乙烯基苯、聚乙烯基甲苯、聚乙烯基二甲苯、聚乙烯基蒽、聚乙烯基萘和二乙烯均四甲苯。示例性的聚乙烯基基团包括二乙烯基基团、三乙烯基基团和四乙烯基基团。在一些实施例中，可使用二乙烯基苯(DVB)并且可包括邻二乙烯基苯、间二乙烯基苯、对二乙烯基苯以及它们的混合物。示例性的杂环聚烯基偶联剂包括二乙烯基吡啶和二乙烯基噻吩。其它示例性的多官能偶联剂包括卤化硅、聚环氧树脂、多异氰酸酯、聚酮、聚酐和二羧酸酯。
在一些实施例中，嵌段共聚物可为线型嵌段共聚物。线型嵌段共聚物可通过下式描述
R-(G)m
其中R代表橡胶态嵌段，G代表玻璃态嵌段，m为玻璃态嵌段的数量，为1或2。在一些实施例中，m为1，并且线型嵌段共聚物是包含一个橡胶态嵌段和一个玻璃态嵌段的二嵌段共聚物。在一些实施例中，m为2，并且线型嵌段共聚物包含两个玻璃态末端嵌段和一个橡胶中间嵌段，即线型嵌段共聚物是三嵌段共聚物。
在一些实施例中，第二嵌段共聚物的橡胶态嵌段包含聚合的共轭双烯、其氢化衍生物或它们的组合。在一些实施例中，共轭双烯包含4至12个碳原子。示例性共轭双烯包括上述示例性共轭双烯中的任一种。
在一些实施例中，第二嵌段共聚物的至少一个玻璃态嵌段，并且在一些实施例中，线型嵌段共聚物的每个玻璃态嵌段包含聚合的单乙烯基芳族单体。在一些实施例中，单乙烯基芳族单体包含8至18个碳原子。示例性聚合单乙烯基芳族单体包括上述示例性聚合单乙烯基芳族单体中的任一种。
在一些实施例中，所述聚合物可包括硅氧烷聚合物。
在一些实施例中，所述聚合物可包括两种或更多种聚合物的共混物(例如高分子量丙烯酸聚合物和低分子量丙烯酸聚合物的共混物)、一种或多种丙烯酸类聚合物与一种或多种嵌段共聚物的共混物等等。
可膨胀聚合物微球通常特征在于柔性、热塑性聚合物外壳包围包括在加热时膨胀的液体和/或气体的芯。市售的可膨胀聚合物微球的实例包括以商品名MICROPEARL可得自Pierce & Stevens(Buffalo，NewYork)和Henkel AG的那些和以商品名EXPANCEL可得自Akzo-Nobel的那些。
一般来讲，基于泡沫的期望特性来选择可膨胀微球的量。通常，微球的量越多，泡沫的最终密度越小。在一些实施例中，泡沫包括在每100份聚合物树脂中至少0.1重量份的可膨胀微球，在一些实施例中，至少0.5重量份的可膨胀微球。在一些实施例中，所述泡沫包括在每100份聚合物树脂中不大于50重量份的可膨胀微球，在一些实施例中，不大于20重量份的可膨胀微球。
本发明的泡沫包括少量高表面积二氧化硅。在一些实施例中，所述泡沫包括在每100份聚合物树脂中0.3至1.5重量份的二氧化硅。在一些实施例中，所述泡沫包括在每100份聚合物树脂中至少0.5，或甚至0.7重量份的二氧化硅。在一些实施例中，所述泡沫包括在每100份聚合物树脂中不大于1.4重量份或甚至不大于1重量份的二氧化硅。
相对于通常作为填料添加的二氧化硅，所述二氧化硅颗粒具有高表面积。在一些实施例中，根据ASTM D1993-03(2008)“用多点BET氮吸附对沉淀二氧化硅表面积的标准测试方法(Standard Test Method forPrecipitated Silica-Surface Area by Multipoint BET Nitrogen Adsorption)”测量，所述二氧化硅颗粒的表面积为至少300平方米/克，在一些实施例中，为至少320平方米/克。
具体实施方式
实施例表1：制备实例所使用的材料。
丙烯酸类聚合物的制备
通过混合90份2-EHA；10份AA；0.15份IRGACURE 651和0.03份IOTG来制备丙烯酸类聚合物1(AP-1)。由包装膜(由CT Film(Dallas，Texas)以VA-24Film销售的0.0635mm厚的乙烯乙酸乙烯酯共聚物膜)形成离散膜包装。将AP-1组合物密封至该膜包装中，其测得为大约10厘米(cm)×5cm×0.5cm厚。在浸入保持在约21℃和约32℃之间的水浴中的同时，使包装暴露于强度为约3.5毫瓦/平方厘米(mW/sqcm)的紫外线(UV)辐射，并且以NIST单位测得约1680毫焦耳/平方厘米(mJ/sqcm)的总能量。形成包装和固化的方法在美国专利No.5,804,610的实例1中有所描述，该文献的主题内容全部以引用方式并入本文中。
根据AP-1的工序制备丙烯酸类聚合物2(AP-2)，不同之处在于使用85份的2-EHA；15份的AA；0.15份的IRGACURE 651；和0.8份的IOTG。相似地，根据用于丙烯酸类聚合物1的工序制备丙烯酸类聚合物3(AP-3)，不同之处在于组合物是95份的2-EHA；5份的AA；0.15份的IRGACURE 651；和0.02份的IOTG。相似地，通过混合45份IOA；45份BA；10份AA；0.15份IRGACURE 651和0.06份IOTG来制备丙烯酸类聚合物4(AP-4)。通过混合90份2-EHA；10份AA；0.15份IRGACURE 651和0.02份IOTG来制备丙烯酸类聚合物AP-5。根据AP-1的工序，将AP-2、AP-3、AP-4和AP-5置于包装中并暴露于UV能量。
以下根据表2中列出的组合物制备固体(未发泡)样品。针对每个样品。AP-1和AP-2的识别量置于配有Brabender供应的BANBURY混合刀片的捏合混合物碗中。在121℃(250°F)和60rpm的条件下将所述材料混合三分钟。
根据动态剪切测试工序评估这些样品。结果列于表2。
动态剪切测试工序。使用N200J底漆(3M公司)来涂覆两块30mm×70mm铝板。条带的25mm×25mm样品置于铝板的涂底漆的表面之间，将它们在端部附近粘合在一起，使得板的70mm维度的未粘合部分沿相反方向延伸。粘合的标本在室温下老化24小时。铝板的未粘合部分夹在INSTRON拉伸试验机的颚中，使得当颚分离时，对条带样品的厚度方向施加剪切力。颚以1.3mm/min(0.05英寸/分钟)分离，并且在表2中报告峰值力。

*根据ASTM D1993-03(2008)“用多点BET氮吸附对沉淀二氧化硅表面积的标准测试方法”测量。
泡沫芯条带制备工序。
表皮粘合剂制备工序。利用60mm共旋转双螺杆挤出机(可得自Berstorff)来配混压敏粘合剂。根据美国专利No.5,393,373制备多模非对称星形嵌段共聚物(“PASBC”)，该文献的主题内容全部以引用方式并入本文。通过用聚苯乙烯标准校准的SEC(尺寸排阻色谱法)测量，聚合物的数均分子量，对于两个端部嵌段，为约4,000道尔顿和约21,500道尔顿，对于臂，为127,000-147,000道尔顿，对于该星形物，为约1,100,000道尔顿。聚苯乙烯含量在9.5重量％和11.5重量％之间。估计高分子量臂的摩尔百分比为约30％。
将多模非对称嵌段共聚物(31.2重量％)和线型苯乙烯异戊二烯-苯乙烯(SIS)嵌段共聚物(KRATON 1161D)(13.4重量％)干燥送料至第一粘合剂挤出机的第一区。利用辊进料挤出机(可得自Berstorff)，将丙烯酸类聚合物AP-4(4重量％)加热并送料进第一粘合剂挤出机的第三区。抗氧化剂(IRGANOX 1010)(1.3重量％)、紫外线吸收剂(TINUVIN328)(1.3重量％)、着色乙烯乙酸乙烯酯(EVA；4900CMB)(0.4重量％)被干燥送料至第一粘合剂挤出机的各区；并且第一增粘剂(REGALITER1125)(30.9重量％)、第二增粘剂(CUMAR 130)(10.3重量％)和增塑剂(NYPLAST 222B)(7.2重量％)被熔融送料至第一粘合剂挤出机的各区。配混的粘合剂被送料至硅树脂涂布盒中。
泡沫芯制备工序。在50mm BONNOT单螺杆挤出机中处理泡沫芯层。挤出机在120℃下工作。混合物随后被送料至双螺杆挤出机(40mmBERSTORFF(ZE-40)共旋转双螺杆挤出机)的区1，并在此与F-100可膨胀聚合物微球混合。使用标准混合螺杆设计，前向输送，然后在区2中捏合段，在区2、区4和区6中反向捏合，在剩余区中采用自擦拭输送元件。螺杆速度为125RPM。挤出机温度设为104℃，并且软管和模具温度设为193℃。这种温度分布防止在混合过程中膨胀，并使可膨胀聚合物微球的破裂最小化。利用NORMAG齿轮泵控制挤出物流。利用KTron KCL-KC20送进器以0.23kg/h的速率将可膨胀聚合物微球定量送进到双螺杆挤出机的区8中。25.4cm宽的锻模在1mm处填入隙片，并在193℃下工作。
配混的芯层被送料至得自Cloeren Inc.(Orange，Texas)的三层、多歧管膜模具的中间层。配混的表皮粘合剂被送料通过50mm BONNOT单螺杆挤出机并被送入到所述三层模具的外层。挤出机在120℃下工作。
一旦从模具中排出，将共挤出层浇注到硅树脂防粘涂覆的浇注辊上。用温度约20℃的水冷却该辊。将冷却的挤出物从浇注辊转移到0.117mm厚的双面硅树脂涂覆的聚乙烯防粘衬垫上，后者以与浇注辊相同的速度输送至幅材输送线的末端。在转移之后，第一表皮粘合剂与所述衬垫接触，而第二表皮粘合剂暴露于空气。所述衬垫具有允许条带在卷绕之后展开而衬垫不混乱的不同防粘性质。
防粘衬垫是本领域中所熟知的，可以使用任何已知的防粘衬垫。通常情况下，防粘衬垫包括涂有剥离材料的膜或纸基材。市售的防粘衬垫包括但不限于涂覆硅树脂的纸张和涂覆硅树脂的膜，如聚酯膜。合适的防粘衬垫也在转让给3M Innovative Properties Company的美国专利No.6,835,422、No.6,805,933、No.6,780,484和No.6,204,350中有所公开。
在支撑于衬垫上的同时利用电子束固化，使泡沫芯和两个粘合剂表皮在幅材上(on-web)交联。采用作用于所述条带的相对面上的两个顺次的辐射步骤。透过聚乙烯衬垫辐射第一表皮粘合剂，而第二表皮粘合剂在表面敞开的条件下被辐射。电子束单元为ELECTROCURTAINCB-300电子束单元(Energy Sciences Inc.(ESI)，Wilmington，Mass.)，加速度电压为300keV并且一剂量为6MRAD。
拉力(Pluck Force)测试工序。制成为6.4mm(1/4英寸)厚的铝的两个T嵌段的30mm×30mm平面涂有得自3M公司的N200J底漆。25mm×25mm样品被置于涂有底漆的表面之间，将两个T嵌段粘合在一起。T-嵌段安装在INSTRON拉伸试验机中，并以1.3mm/min(0.05英寸/分钟)的速度拉开。峰值分离力报告为以千克力为单位的“拉力”。
角裂解(Angle Cleavage)测试工序。铝的30mm×30mm×30mm L-形零件在一个30mm×30mm面上涂有得自3M公司的N200J底漆。涂有底漆的表面粘合到25mm×25mm样品的一个表面上。样品的相对表面粘合到同样涂覆有N200J底漆的阳极氧化铝面板上。用INSTRON拉伸试验机以2.5mm/min(0.1英寸/分钟)的速率拉动铝的L-形零件的垂直于涂底漆的面的腿。峰值力以千克力单位报告于表4中。
泡沫条带根据泡沫芯条带制备工序进行制备。在表3中总结了泡沫芯组合物。在表3中也报告了利用拉力测试工序测试的拉力。

*每立方英尺38磅
角裂解测试工序也用于评估在添加或不添加少量高表面积二氧化硅的情况下具有替代形式芯组合物的泡沫条带。根据泡沫芯制备工序制备条带样品，不同之处在于，条带以225kEV和10MRAD从带衬侧被电子束固化，并且以250kEV和15MRAD从不带衬侧被电子束固化。在表5中报告了条带芯组合物和角裂解力。

根据本发明一些实施例的示例性泡沫示于图1中。泡沫10包括分散在聚合物20中的至少部分膨胀的可膨胀聚合物微球30和二氧化硅40。
如图2所示，在本发明的一些实施例中，泡沫条带可被制备为包括这种泡沫。泡沫条带100包括泡沫10和粘合到泡沫10的第一表面11的第一粘合剂层50。在一些实施例中，泡沫条带100还包括粘合到泡沫10的第二表面12的第二粘合剂层60。在一些实施例中，单或双粘合剂层可以与泡沫直接粘结。在一些实施例中，至少一个粘合剂层可间接粘合到泡沫上。也就是说，一个或多个中间层例如底漆层，可存在于粘合剂层和泡沫芯之间。
在不脱离本发明的范围和精神的前提下，对本发明进行的各种修改和更改对本领域内的技术人员来说将是显而易见的。
