Description

在造纸中提高填料含量的方法及材料组合物
技术领域
本发明涉及提高在造纸工艺中所生产的纤维纸板(paper mat)的强度的方法。 
发明背景 
纸板包括水和固体,并且一般是4%到8%的水。纸板的固体部分包括纤维(通常纤维素纤维),并且还可包括填料。提高纸板的强度将容许提高固体比例,即填料含量。由于这样降低了原材料成本,减少了在造纸工艺中所需的能量,并且提高了纸的光学性能,所以这是所期望的。现有技术公开了具有介于10%与40%填料的固体部分的纸板。然而,现有技术还公开了提高填料含量同时发生了所得纸的强度损失。 
填料是在造纸工艺期间被添加到纸板以增强所得纸的不透明性和反光性的矿物颗粒。在美国专利第7,211,608号中描述了填料的一些例子。填料包括用来增加不透明性或亮度、减少孔隙率或降低纸或纸板片的成本的无机颗粒和有机颗粒或颜料。填料的一些例子包括下列中的一个或多个:高岭土、滑石、二氧化钛、三水合氧化铝、硫酸钡、氢氧化镁、颜料例如碳酸钙、及类似物。先前提高纸中的填料含量而不损失纸强度的尝试描述在英国专利GB2016498和美国专利第4,710,270、4,181,567、2,037,525、7,211,608和6,190,663号中。 
碳酸钙填料采用两种形式:GCC(研磨碳酸钙)和PCC(沉淀碳酸钙)。GCC是天然存在的碳酸钙岩石,而PCC是合成生产的碳酸钙。由于PCC具有较大的比表面积,所以PCC具有较好的光散射性能并且给所得纸提供较好的光学性能。然而,由于同样的原因,PCC填充的纸板所生产的纸比GCC填充的纸强度差。 
纸强度是纸板的交织纤维之间所形成的键的数量和强度的函数。具有更大表面积的填料颗粒更可能变得与那些纤维结合并且影响那些键的数量和强度。由于PCC填料的更大的表面积,所以PCC填料比GCC填料对那些键影响更大。 
结果,造纸者被迫进行不期望的权衡。他们必须决定选择具有较好强度但较差光学性能的纸,或者他们必须选择具有较好光学性能但较差强度的纸。因而,对促进在纸中更高填料含量的造纸方法、具有高不透明性的纸、以及具有高强度的填充纸,有明显的需求。

发明详述 
本发明的至少一种实施方案是制造结实的、具有高填料含量、具有高PCC含量和具有较好的光学性能的纸的方法。在本发明的至少一种实施方案中,造纸方法包括以下步骤:产生PCC和GCC的填料共混料,其中PCC构成填料的按质量计的至少10%,且GCC构成填料质量的至少10%;用降低强度添加剂与填料颗粒之间的附着力的涂料来预处理至少一些填料颗粒;以及将填料共混料和强度添加剂都添加到纸板。 
已知有一段时间了,将强度添加剂添加到纸板提高了所得纸的强度。在美国专利第4,605,702号中描述了强度添加剂的一些例子。强度添加剂的一些例子是阳离子淀粉,其粘附到纤维素纤维并且将它们紧紧地结合到一起。 
不幸地,添加大量的强度添加剂以补偿由在纸板中使用大量的填料引起的脆弱(weakness)是不切实际的。一个原因是由于强度添加剂是昂贵的并且使用大量的添加剂会导致商业上不可行的生产成本。另外,添加太多的强度添加剂负面影响造纸工艺并且抑制了各种形式的造纸设备的可操作性。举例来说,在阳离子淀粉强度添加剂的情况下,阳离子淀粉延缓滤水过程和脱水过程,这大大地减慢了造纸工艺。 
此外,纤维素纤维仅仅能吸附有限量的强度添加剂。这对可使用多少添加剂和由此可使用多少填料施加了限制。为什么如此的一个原因是由于强度添加剂倾向于中和阴离子纤维/填料电荷,并且当这些电荷过多地被中和时,抑制了强度添加剂的进一步吸附。 
不幸地,将填料添加到纸板还降低了强度添加剂的效率。强度添加剂具有涂覆填料颗粒的倾向。存在的填料颗粒越多,就有越多的强度添加剂涂覆填料颗粒,并且因此就有越少的强度添加剂可用来使纤维素纤维结合 到一起。因为存在可添加的强度添加剂的最大量,所以越多的填料往往意味着越少有效的强度添加剂。这种效应PCC比GCC更敏感,由于PCC更高的表面积而使PCC变得比GCC更多地被强度添加剂涂覆。 
在本发明的至少一种实施方案中,用材料组合物预处理至少一些填料颗粒以至少部分地防止强度添加剂粘附到填料颗粒。预处理预期用该材料组合物彻底地涂覆一种或多种填料颗粒中的一些或全部。在可选择的方案中,预处理预期将该材料组合物应用到填料颗粒的一种或多种中的仅仅一部分,或者完全涂覆一些填料颗粒并且将该材料组合物应用到一些其它颗粒中的仅仅一部分。在至少一种实施方案中,用美国专利第5,221,435号中所述的材料组合物中的至少一些并且尤其是用其中所述的偏阳离子电荷物质(cationic charge-biasing species)来实施预处理。在至少一种实施方案中,用在美国专利第6,592,718号中所述的二烯丙基-N,N-二取代的卤化铵-丙烯酰胺共聚物来实施预处理。 
虽然预处理填料颗粒在本领域是已知的,但是预处理填料颗粒的现有技术方法并未涉及影响强度添加剂到填料颗粒的粘附。实际上,许多现有技术预处理增加了强度添加剂到填料颗粒的粘附。例如,美国专利第7,211,608号描述了用疏水聚合物预处理填料颗粒的方法。然而,该预处理对强度添加剂与填料颗粒之间的粘附不起作用,并且只不过排斥水以抵消被强度添加剂所吸收的过量的水。相比之下,本发明减少了强度添加剂与填料颗粒之间的相互作用,并且在纸强度方面产生预料不到的巨大增加。可参考图1来最好地理解这点。 
图1绘制了给定纸的抗张强度对填料相对于用来生产给定纸的纸板的总固体部分的百分比的关系曲线。如图1中所示,增加填料含量与降低纸强度之间的关系是线性关系。这是由于强度添加剂的降低的效率与填料颗粒所捕获的强度添加剂的增加成正比。图1还示出了对于现有技术填料对纸板的任意给定比例,与如果填料是部分的GCC相比较,如果填料是纯的PCC,那么它往往会具有较低的强度。 
图1还示出了根据本发明方法制造的纸具有预料不到的高强度。在图1中,含有32%按质量计的用强度添加剂-排斥凝结剂(strength additive-repelling coagulant)预处理过的50%PCC和50%GCC的填料的纸板试样生产的纸比用仅有20%纯的GCC填料的纸板所生产的纸具有更大的强度。这个结果是双重预料不到的,因为a)含有PCC的填料比纯GCC填料产生了更大强度的纸,以及b)在容许的填料方面增加大于12%是非常大的。高的纸强度是减少纤维素纤维键之间影响的GCC含量以及容许强度添加剂来达到或接近达到最大纸强度的预处理的结果。 
本发明所包括的填料中的至少一些填料是熟知的和商业上可获得的。它们包括用来增加不透明性或亮度、减少孔隙率或降低纸或纸板片的成本的任何无机颗粒或有机颗粒或颜料。最常用的填料是碳酸钙和粘土。然而,滑石、二氧化钛、三水合氧化铝、硫酸钡和氢氧化镁也是合适的填料。碳酸钙包括以无水形式或分散浆料形式的研磨碳酸钙(GCC)、白垩、任何形态的沉淀碳酸钙(PCC)、以及以分散浆料形式的沉淀碳酸钙。GCC或PCC的分散浆料形式通常采用聚丙烯酸聚合物分散剂或聚磷酸钠分散剂来生产。这些分散剂中的每一种分散剂将有效的阴离子电荷给予碳酸钙颗粒。高岭土浆也可用聚丙烯酸聚合物或聚磷酸钠来分散。 
在至少一种实施方案中,处理材料组合物是美国专利6,592,718中所述的材料组合物中的任一种或组合。具体地,在其中详细描述的AcAm/DADMAC共聚物组合物中的任一种适合作为处理材料组合物。AcAm/DADMAC共聚物组合物的一个例子是来自伊利诺斯州内珀维尔的Nalco Company的产品#Nalco-7527(以下称作7527)。 
处理材料组合物可以是凝结剂。本发明中所包括的凝结剂是熟知的并商业上可获得的。它们可以是无机凝结剂或有机凝结剂。代表性的无机凝结剂包括明矾、铝酸钠、聚氯化铝或PAC(也称作碱式氯化铝、氢氧化铝氯化物和聚羟基氯化铝)、硫酸化聚氯化铝、聚硅硫酸铝、硫酸铁、氯化铁和类似物及其共混料。 
适合作为处理材料组合物的一些有机凝结剂通过缩聚来形成。这种类型的聚合物的例子包括表氯醇-二甲胺(EPI-DMA)和EPI-DMA氨交联聚合物。 
适合作为处理材料组合物的另外的凝结剂包括二氯化乙烯与氨或者 二氯化乙烯与二甲胺在添加氨或不添加氨下的聚合物;多官能胺如二亚乙基三胺、四亚乙基五胺、六亚甲基二胺及类似物与二氯化乙烯的缩聚物;以及通过例如三聚氰胺甲醛树脂的缩合反应制备的聚合物。 
适合作为处理材料组合物的另外的凝结剂包括带阳离子电荷的乙烯基加聚物,例如(甲基)丙烯酰胺、二烯丙基-N,N-二取代的卤化铵、甲基丙烯酸二甲氨基乙酯和其季铵盐、丙烯酸二甲氨基乙酯和其季铵盐、甲基丙烯酰胺丙基三甲基铵氯化物、二烯丙基甲基(β-丙酰胺基)铵氯化物、(β-甲基丙烯酰氧基乙基)三甲基铵甲基硫酸盐((beta-methacryloyloxyethyl)trimethyl ammonium methylsulfate)、季铵化聚乙烯基内酰胺、乙烯胺、和已经反应生成Mannich衍生物或四元Mannich衍生物的丙烯酰胺或甲基丙烯酰胺中的聚合物、共聚物和三元共聚物。可采用甲基氯、硫酸二甲酯和苄基氯来生成优选的季铵盐。三元共聚物可包括阴离子单体如丙烯酸或2-丙烯酰氨基2-甲基丙烷磺酸,条件是聚合物上的总电荷是阳离子的。乙烯基加成和缩合的这些聚合物的分子量从低至几百到高达几百万变动。优选地,分子量范围应该从大约20,000至大约1,000,000。在至少一种实施方案中,由描述为用于预处理填料颗粒的适合的材料组合物的材料组合物中的任一种中的一种、一些或者所有的组合来实施预处理。

在至少一种实施方案中,所使用的填料是PCC、GCC和/或高岭土。在至少一种实施方案中,所使用的填料是带有聚丙烯酸聚合物分散剂或它们的共混料的PCC、GCC和/或高岭土。强度添加剂相对于固体纸板之比率可以是每吨纸板3千克添加剂。 
参考下列实施例可更好的理解上述内容,下列实施例是为了说明目的而呈现且并不旨在限制本发明的范围。 
具体实施方式
实施例1 
1(i)填料预处理: 
从造纸厂获得填料颗粒的共混料。该共混料是50%PCC与50%GCC的混合物。PCC是未分散的Albacar HO(由宾夕法尼亚州伯利恒的SpecialtyMineral公司制造),并且GCC(也是由宾夕法尼亚州伯利恒的SpecialtyMineral公司制造)是化学上分散的。对于本申请来说,术语“未分散的”的定义是不借助于化学分散剂就被分布在流体之中。对于本申请来说,术语“化学上分散的”的定义是借助于化学分散剂被分布在流体之中。 
用自来水将填料共混料稀释到18%固体含量。将200毫升稀释的填料共混料放置到500毫升玻璃烧杯中。在添加凝结剂之前进行搅拌至少30秒。搅拌器是EUROSTAR数字高架搅拌器,带有R1342、50毫米的四叶螺旋桨(four-blade propeller)(都来自北卡罗来纳州威尔明顿的IKA Works,Inc.)。在800rpm搅拌下初始混合30秒后,缓慢添加凝结剂溶液。使用的凝结剂溶液是7527。基于无水填料重量,凝结剂的剂量是1千克/吨。在800rpm继续搅拌直至添加了所有的凝结剂。然后搅拌速度增加到1500rpm,保持一分钟。 
1(ii)填料的使用: 
从造纸厂获得纤维素纤维的稠原料。将原料冷却,然后用澄清白水稀释到近似0.7%的稠度。纤维素纤维是60%硬木漂白牛皮浆(HBKP)、20%软木漂白牛皮浆(SBKP)和20%漂白的化学热磨机械浆(BCTMP)。添加了图1所示的各种填料组合物试样。还添加了强度添加剂64170。然后测量用每种试样制备的纸的抗张强度并绘制在图1。 
试样的强度分析显示如下:用50%PCC和50%GCC代替纯的PCC一贯地容许填料含量增加近似3%而纸强度无任何损失。然而,50%PCC 和50%GCC填料的组合,其中用强度添加剂64170和排斥凝结剂7527对GCC颗粒预处理,使得容许填料含量增加令人惊奇的12%而纸强度毫无损失。因此,很明显,本发明方法的步骤容许更多填料将被用在造纸中、更多的PCC将被用在造纸中,同时改善了所得纸的光学性能。 
实施例2 
如实施例1中提供纤维素混合物和填料。如实施例1中处理填料。将3千克/吨强度添加剂64170添加到三份试样中,一份含有100%PCC,一份含有50%PCC-50%GCC,以及一份含有50%PCC-50%GCC且GCC用7527预处理。分析所得纸试样,结果显示在图2,图2绘制了给定纸的抗张强度对填料相对于用来生产给定纸的纸板的总固体部分的百分比的关系曲线。 
当3千克/吨添加剂64170与100%PCC一起添加时,仅仅能提高3%填料含量而无强度损失。在大约34%填料含量时,强度提高12%。当100%PCC换成50%PCC-50%GCC时,强度增加了并且可以容许填料含量增加3.5%而不损失纸片强度。当添加3千克/吨添加剂64170时,填料含量可以增加大约另外的2.5%而不牺牲纸片强度。在35%填料含量时,外加3千克/吨64170,纸片强度增加14%。与50%PCC-50%GCC相比较,7527预处理的50%PCC-50%GCC可增加2%填料而不损失强度。当将3千克/吨N-64170添加到具有预处理的50%PCC-50%GCC的配料中时,与仅仅预处理的50%PCC-50%GCC相比较,填料含量可增加4%而不损失纸片强度。在36%填料含量时,添加3千克/吨N-64170增加19%的强度。本试验表明,用同样量的强度添加剂64170,通过预处理填料,显著地增加改善纸片强度的效率。 
实施例3 
运行机器试验,其中造纸机以1360米/分钟的机器速度制备108gsm涂布原纸。提供组合物,其中的纤维素纤维是40%漂白的化学热磨机械浆(BCTMP)、40%HBKP、20%SBKP。配料还含有填料共混料,其是70%PCC和30%GCC。试验期间,包括助留剂、上浆剂和阳离子淀粉的所有湿部添加剂保持恒定。采用斯科特粘合力试验仪(Scott Bond tester)测量 所得纸强度。 
图3示出了纸共混料的所得的斯科特粘接强度,所述纸共混料包括具有不同量的7527和64170的8种共混料。当不添加7527且不添加64170时,强度是0.92千克·厘米。当添加2.5千克/吨64170时,强度增加到1.14千克·厘米,强度提高24%。然而,当进一步添加0.5千克/吨7527时,强度从1.14千克·厘米增加到1.30千克·厘米,进一步提高14%。本试验表明,添加少量的凝结剂,大大提高了64170的效率。 
本领域普通技术人员将认识到,所有先前所述的方法也可应用到含有其它非纤维素纤维材料的纸板、含有纤维素纤维材料和非纤维素纤维材料和/或合成纤维材料的混合物的纸板。 
在此处所述的本发明方法的组合物、操作和配置上可以进行变动,而不背离如权利要求中所限定的本发明的原理和范围。虽然可以许多不同形式来使本发明具体化,但是此处详细描述本发明的特定优选的实施方案。本公开内容是本发明的原理的示例,且并不规定为使本发明限于所示的具体实施方案。此外,本发明包括此处所述的各种实施方案的一些或全部的任意可能的组合。在本申请中或在任一个引用的专利、引用的专利申请或其它引用的资料中任何地方所提及的所有专利、专利申请和其它引用资料据此通过引用以其整体并入。 
以上公开内容规定为说明性的而不是穷尽性的。对于本领域普通技术人员来说,本说明书将暗示许多变化和可选择方案。所有这些可选择方案和变化规定为被包括在本权利要求的范围内,其中术语“包括”意思是“包括,但不限于”。那些熟悉本领域的人员可认识到此处所述的特定实施方案的其它等效变换,这些等效变换也规定为由本权利要求所包括。 
在此完成了对本发明的优选的和可选择的实施方案的描述。那些本领域技术人员可认识到此处所述的特定实施方案的其它等效变换,这些等效变换规定为由附于本文的权利要求所包括。
