Description

高淀粉轻质石膏墙板
本申请是申请日为2006年6月8日、申请号为200680019824.7、发明名称为“高淀粉轻质石膏墙板”的发明专利申请的分案申请。
技术领域
本发明涉及一种制备含有预胶质化淀粉和萘磺酸盐分散剂的石膏浆液的方法，和由所述石膏浆液制得的产品。本发明还涉及一种增加包括墙板在内的含石膏产品的干强度的方法，其是通过在用于制造所述产品的浆液中使用与预胶质化淀粉组合的萘磺酸盐分散剂来进行。
背景技术
石膏（二水合硫酸钙）的某些特性使其非常适合用于制造工业和建筑产品，诸如石膏墙板。石膏是一种蕴藏丰富并且通常极为廉价的原材料，通过脱水和再水合的过程，能够对其进行浇注、模制或另外使其形成有用的形状。制造石膏墙板和其它石膏产品的基本材料是通常称为“灰泥”的半水合形式的硫酸钙（CaSO4·1/2H2O），它是通过加热转化二水合形式的硫酸钙（CaSO4·2H2O），由去除其1-1/2个水分子得到。
常规的含石膏产品（诸如石膏墙板）具有多种益处，诸如成本低和易于加工，但当切割或钻开所述产品时，会产生大量的石膏粉尘。已使用淀粉作为用于制造所述产品的浆液中的成分来实现对制造含石膏产品的方法的多种改进。淀粉可增加包括石膏墙板在内的含石膏产品的抗弯强度和压缩强度。已知的石膏墙板含有小于约10lbs/MSF含量的纸板淀粉（board starch）。
还需要在含有预胶质化淀粉的石膏浆液中使用大量的水以便确保所述浆液的适当流动性。不幸的是，大部分的水最终都必须通过加热来分离去除，这一步骤因加热过程中所用的燃料具有较高成本而显得代价太大。加热步骤还相当费时。已发现，使用萘磺酸盐分散剂能够增加浆液的流动性，从而克服需水的问题。此外，还发现，如果使用量足够高，那么萘磺酸盐分散剂能够与预胶质化淀粉交联以在干燥后结合石膏晶体，从而增加石膏复合物的干强度。过去，并未认识到三偏磷酸盐能够影响石膏浆液的需水量。然而，本发明的发明者已发现，在特定分散剂的存在下，将三偏磷酸盐的含量增加到目前尚未知的程度甚至在高淀粉含量的存在下仍可能会实现适当的浆液流动性，和出人意料地降低的水量。当然，由于增加三偏磷酸盐含量随之减少了燃料的使用以及与随后去除水的处理步骤相关的处理时间，故而变得特别合乎需要。由此，本发明的发明者还发现，通过在用于制造石膏板的浆液中使用与预胶质化淀粉组合的萘磺酸盐分散剂将能够增加所述墙板的干强度。
发明内容
本发明大体来说包含一种包括灰泥、萘磺酸盐分散剂和预胶质化淀粉的浆液。以干灰泥的重量计，所述萘磺酸盐分散剂是以约0.1重量%-3.0重量%的量存在。以所述调配物中干灰泥的重量计，所述预胶质化淀粉是以至少约0.5重量%多达约10重量%的量存在。其它浆液添加剂可包括加速剂、粘合剂、纸纤维或玻璃纤维和其它已知的组分。本发明还包含用所述浆液制成的含石膏产品。
本发明还包含一种包括灰泥、三偏磷酸盐、萘磺酸盐分散剂和预胶质化淀粉的浆液。以干灰泥的重量计，所述三偏磷酸钠是以至少约0.12重量%的量存在。在优选实施例中，以干灰泥的重量计，所述三偏磷酸盐是以约0.12-0.4重量%的量存在。以干灰泥的重量计，所述萘磺酸盐分散剂是以约0.1重量%-3.0重量%的量存在。以所述调配物中干灰泥的重量计，所述预胶质化淀粉是以至少约0.5重量%多达约10重量%的量存在。其它浆液添加剂可包括加速剂、粘合剂、纸纤维或玻璃纤维和其它已知的组分。本发明还包含用所述浆液制成的含石膏产品。
优选的含石膏产品为石膏墙板。在本实施例中，本发明构造包含形成于两个大体平行的盖板之间的凝固石膏组合物的石膏墙板，所述凝固石膏组合物是使用由水、灰泥、预胶质化淀粉和萘磺酸盐分散剂构成的含石膏浆液制成。含石膏浆液可视情况含有三偏磷酸盐，例如三偏磷酸钠。根据本发明制成的这种石膏墙板具有高强度，但重量比常规板轻得多。此外，当切割、锯开、扳断或钻开根据本发明制成的墙板时，将产生少得多的粉尘。
在另一实施例中，本发明提供一种通过混合包含水、灰泥、预胶质化淀粉和萘磺酸盐分散剂的含石膏浆液来制造石膏墙板的方法，其中以灰泥的重量计，所述预胶质化淀粉是以至少约0.5重量%多达约10重量%的量存在。将所得的含石膏浆液沉积于第一个纸盖板上，并且将第二个纸盖板放到已沉积的浆液上以形成石膏墙板。当含石膏浆液硬化到足以进行切割后，对石膏墙板进行切割，并且干燥所得到的石膏墙板。含石膏浆液可视情况含有三偏磷酸盐，例如三偏磷酸钠。还可将其它常用成分用于浆液中，包括（适当时）加速剂、粘合剂、纸纤维、玻璃纤维和其它已知的成分。通常还加入肥皂泡沫以减小最终的石膏墙板产品的密度。

具体实施方式
根据本发明的一个实施例，提供由含有灰泥、预胶质化淀粉和萘磺酸盐分散剂的含石膏浆液制成的含石膏成品。以干灰泥的重量计，所述萘磺酸盐分散剂是以约0.1重量%-3.0重量%的量存在。以所述调配物中干灰泥的重量计，所述预胶质化淀粉是以至少约0.5重量%多达约10重量%的量存在。所述浆液中可使用的其它成分包括粘合剂、纸纤维、玻璃纤维和加速剂。通常还将肥皂泡沫加入新调配的含石膏浆液中，以降低最终的含石膏产品（例如，石膏墙板）的密度。
视情况，约0.5重量%多达约10重量%的预胶质化淀粉、约0.1重量%多达约3.0重量%的萘磺酸盐分散剂和最小为至少约0.12重量%多达约0.4重量%的三偏磷酸盐（所有物质都是以石膏浆液中所使用的干灰泥的重量计）的组合将出人意料地明显增加所述石膏浆液的流动性。这将大体上减少制备具有足够的流动性待用于制造含石膏产品（诸如石膏墙板）的石膏浆液所需的水量。相信为标准调配物中含量的至少约2倍的三偏磷酸盐的含量（以三偏磷酸钠的形式）将会增强萘磺酸盐分散剂的分散剂活性。
用于本发明中的萘磺酸盐分散剂包括聚萘磺酸和其盐（聚萘磺酸盐）和衍生物，其为萘磺酸与甲醛的缩合产物。特别合乎需要的聚萘磺酸盐包括萘磺酸钠和萘磺酸钙。萘磺酸盐的平均分子量可在约3,000到27,000的范围内，但所述分子量优选为约8,000到10,000。在给定固体百分比的水溶液中，较高分子量的分散剂具有较高的粘度，并且在调配过程中产生比较低分子量分散剂高的需水量。有用的萘磺酸盐包括购自GEOSpecialty Chemicals,Cleveland,Ohio的DILOFLO；购自Hampshire Chemical Corp.,Lexington,Massachusetts的DAXAD；和购自GEO Specialty Chemicals,Lafayette,Indiana的LOMAR D。萘磺酸盐优选是以（例如）固含量在35-55重量%的范围内的水溶液的形式使用。最优选使用（例如）固含量在约40-45重量%的范围内的水溶液形式的萘磺酸盐。或者，适当时，萘磺酸盐可以干固体或粉末形式使用，诸如LOMAR D。可用于本发明中的聚萘磺酸盐具有通用结构（I）：

其中n>2，且其中M为钠、钾、钙等。
以石膏复合物调配物中所使用的干灰泥的重量计，优选为约45重量%的水溶液形式的萘磺酸盐分散剂可以在约0.5重量%到约3.0重量%范围内的量使用。以干灰泥的重量计，萘磺酸盐分散剂的更优选范围为约0.5重量%到约2.0重量%，并且以干灰泥的重量计，最优选的范围为约0.7重量%到约2.0重量%。相比之下，已知的石膏墙板含有以干灰泥的重量计约0.4重量%或更低含量的所述分散剂。
换种方式说，以石膏复合物调配物中所使用的干灰泥的重量计，萘磺酸盐分散剂以干重计可以在约0.1重量%到约1.5重量%范围内的量使用。以干灰泥的重量计，萘磺酸盐分散剂更优选范围（以干固体计）为约0.25重量%到约0.7重量%，并且以干灰泥的重量计，最优选的范围（以干固体计）为约0.3重量%到约0.7重量%。
含石膏浆液可视情况含有三偏磷酸盐，例如三偏磷酸钠。任何适当的水溶性偏磷酸盐或聚磷酸盐都可用于本发明中。优选使用三偏磷酸盐，包括复盐，也就是具有两个阳离子的三偏磷酸盐。特别有用的三偏磷酸盐包括三偏磷酸钠、三偏磷酸钾、三偏磷酸钙、三偏磷酸钠钙、三偏磷酸锂、三偏磷酸铵等，或其组合。优选的三偏磷酸盐为三偏磷酸钠。优选使用（例如）固含量在约10-15重量%的范围内的水溶液形式的三偏磷酸盐。如以引用方式并入本文中的Yu等人的美国专利第6,409,825号中所述，还可使用其它环状或无环聚磷酸盐。
三偏磷酸钠是一种含石膏组合物中的已知添加剂，但以石膏浆液中所使用的干灰泥的重量计，其通常是以在约0.05重量%到约0.08重量%范围内的量使用。在本发明的实施例中，以石膏复合物调配物中所使用的干灰泥的重量计，三偏磷酸钠（或其它水溶性偏磷酸盐或聚磷酸盐）可以在约0.12重量%到约0.4重量%范围内的量存在。以石膏复合物调配物中所使用的干灰泥的重量计，三偏磷酸钠（或其它水溶性偏磷酸盐或聚磷酸盐）的优选范围为约0.12重量%到约0.3重量%。
存在两种形式的灰泥，α和β。这两类灰泥是由不同的煅烧方式制得。在本发明中，可使用β或α形式的灰泥。
在根据本发明所制备的含石膏浆液中，必须使用淀粉（尤其包括预胶质化淀粉）。优选预胶质化淀粉为预胶质化玉米淀粉，例如，购自Bunge Milling,St.Louis,Missouri的预胶质化玉米粉，其具有以下典型分析：水分7.5%，蛋白质8.0%，油0.5%，粗纤维0.5%，灰分0.3%；生坯强度为0.48psi；且松装密度为35.0lb/ft3。以含石膏浆液中所使用的干灰泥的重量计，所述预胶质化玉米淀粉应以至少约0.5重量%多达约10重量%的量使用。
本发明的发明者还发现，在约0.1重量%到3.0重量%的萘磺酸盐分散剂的存在下，通过使用至少约0.5重量%至多达约10重量%的预胶质化淀粉（优选为预胶质化玉米淀粉）（淀粉和萘磺酸盐含量都是以调配物中存在的干灰泥的重量计）能够使干强度（尤其在墙板中）获得意外增加。这出人意料的结果能够在存在或不存在水溶性偏磷酸盐或聚磷酸盐的情况下获得。
此外，还意外地发现，预胶质化淀粉可以至少约10lb/MSF或更高的含量用于根据本发明制成的干石膏墙板中，而且仍能够实现高强度和低重量。石膏墙板中高达35-45lb/MSF的预胶质化淀粉含量被证实是有效的。举例来说，如下表1和表2中所示，调配物B包括45lb/MSF，但产生具有优良强度的1042lb/MSF的纸板重量。在本实例（调配物B）中，呈45重量%水溶液形式的萘磺酸盐分散剂是以1.28重量%的含量使用。
其它有用的淀粉包括经酸改性的淀粉，诸如经酸改性的玉米粉，如购自BungeMilling,St.Louis,Missouri的HI-BOND。这种淀粉具有以下典型分析：水分10.0%，油1.4%，可溶物17.0%，碱性流动性98.0%，松装密度30lb/ft3，和产生4.3的pH值的20%浆液。另一种有用淀粉为未预胶质化小麦淀粉，诸如购自ADM/Ogilvie,Montreal,Quebec,Canada的ECOSOL-45。
当将萘磺酸盐分散剂三偏磷酸盐的组合与预胶质化玉米淀粉和视情况纸纤维或玻璃纤维组合时，用本发明可实现另一出人意料的结果。由含有这三种成分的调配物制成的石膏墙板具有增加的强度和减轻的重量，并且因其生产过程中所需的水量减少而在经济上更合乎需要。
如以引用的方式并入本文中的Yu等人的美国专利第6,409,825号中所述，可以将加速剂用于本发明的含石膏组合物中。一种合乎需要的耐热加速剂（HRA）可由干磨的建筑石膏粉（landplaster）（二水合硫酸钙）制得。可使用少量诸如糖、右旋糖、硼酸和淀粉等添加剂（通常约5重量%）制得此HRA。当前优选糖或右旋糖。如以引用的方式并入本文中的美国专利第3,573,947号所述，另一种有用的加速剂为“气候稳定的加速剂（climate stabilized accelerator）”或“气候可稳定加速剂”（CSA）。
以下实例将进一步说明本发明。不应将其解释为以任何方式限制本发明的范围。

如表2中所述，相比对照纸板，使用调配物A和B浆液所制得的石膏墙板的重量明显减轻。再参看表1，调配物A纸板与调配物B纸板相差极大。调配物A与调配物B的水/灰泥（w/s）比类似。调配物B中还使用明显较高含量的萘磺酸盐分散剂。此外，在调配物B中使用约6重量%的实质更多的预胶质化淀粉，这比调配物A增加超过100%，同时伴随明显的强度增加。即使这样，产生所需的流动性的需水量对调配物B浆液而言仍较低，与调配物A相比，差异为约10%。两种调配物的低需水量归因于石膏浆液中萘磺酸盐分散剂和三偏磷酸钠组合的协同作用，这使得甚至在存在实质更高含量的预胶质化淀粉的情况下仍能增加石膏浆液的流动性。
如表2所述，相比使用调配物A浆液所制得的墙板，使用调配物B浆液所制得的墙板具有实质上增加的强度。通过并入与增加量的萘磺酸盐分散剂和三偏磷酸钠组合的增加量的预胶质化淀粉，调配物B纸板的拔钉抗性相比调配物A纸板改进45%。与调配物A纸板相比，在调配物B纸板中还观察到抗弯强度的实质增加。

包括浆液调配物和试验结果在内的其它石膏墙板实例（纸板C、D和E）都展示于下表3中。表3中的浆液调配物包括所述浆液中的主要组分。括号中的值是基于干灰泥的重量以重量百分比表示。

1DILOFLO为45%的萘磺酸盐水溶液
如表3中所述，纸板C、D和E都是由与对照纸板相比淀粉、DILOFLO分散剂和三偏磷酸钠的量显著增加（淀粉和分散剂以百分比计约两倍增加；且三偏磷酸盐增加2到3倍）而同时w/s比保持恒定的浆液制成。然而，如通过拔钉抗性测量到的强度未受到明显影响并且纸板重量明显减轻。因此，在本发明实施例的这一实例中，新颖调配物（诸如，纸板D）可将增加的淀粉调配于保持适当强度的同时还便于使用的可流动浆液中。
实例4
湿石膏立方块强度试验
湿立方块强度试验是在实验室中通过使用购自United States Gypsum公司,Chicago,Illinois的Southard CKS纸板灰泥和自来水进行以测定其湿压缩强度。使用以下实验室试验程序。
在约70℉下，将灰泥（1000g）、CSA（2g）和自来水（1200cc）用于各湿石膏立方块浇注。首先，在塑料袋中将预胶质化玉米淀粉（20g，以灰泥重量计为2.0%）和CSA（2g，以灰泥重量计为0.2%）与灰泥彻底干拌混合，随后使其与含有萘磺酸盐分散剂与三偏磷酸钠的自来水溶液混合。所使用的分散剂为DILOFLO分散剂（1.0-2.0%，如表4中所示）。还如表4中所示使用变化量的三偏磷酸钠。
最初，在实验室用Warning混合机组合干成分和水溶液，将所产生的混合物浸泡10秒，且随后以低速混合所述混合物10秒以便制成浆液。将由此形成的浆液浇注到三个2"×2"×2"的立方体模具中。随后将所浇注的立方块从模具中取出，称重并且密封于塑料袋中以防止水分在进行压缩强度试验之前损失。湿立方块的压缩强度是使用ATS机测量，并且记录为以每平方英寸的磅数（psi）表示的平均值。所得结果如下：

如表4中所述，三偏磷酸钠含量在约0.12-0.4%范围内的本发明的样本4-5、10-11和17相比三偏磷酸钠含量在此范围外的样本通常具有优良的湿立方块压缩强度。

3应了解，在这些试验条件下，破坏百分率<50%是可接受的。
如表5中所述，实验纸板1和2都是由相比对照纸板淀粉、DILOFLO分散剂和三偏磷酸钠的量实质增加而同时w/s比略有降低的浆液制成。然而，如通过拔钉抗性和抗弯试验所测量到的强度仍得以保持或得到改进，并且纸板重量明显减轻。因此，在本发明的实施例的这一实例中，新颖调配物（诸如，实验纸板1和2）可将增加的三偏磷酸盐和淀粉调配于便于使用的可流动浆液中，同时还保持适当强度。

与实例2一样，使用调配物B（实例1）进行其它实验（实验纸板3和4），但预胶质化玉米淀粉是用水以10%的浓度制备（湿淀粉制剂）并且使用HYONIC PFM肥皂（购自GEO Specialty Chemicals,Lafayette,Indiana）的掺合物。举例来说，实验纸板3是用在65-70重量%/35-30重量%范围内的HYONIC PFM10/HYONIC PFM33的掺合物制造。举例来说，实验纸板4是用70/30wt./wt.的HYONIC PFM10/HYONIC PFM33的掺合物制造。实验结果展示于下表6中。
