Description
本发明涉及一种隔热性成形体的制作方法，所述的成形体具有隔热性并且是以发泡碱金属硅酸盐颗粒为基，该发泡碱金属硅酸盐颗粒含有二氧化硅（SiO2）和碱金属氧化物（M2O）（M是一种碱金属），其中SiO2和M2O的摩尔比为2～4.5。本发明还涉及按本发明的方法生产的成形体的应用。
日本公布的专利说明书JP-49069755也描述了一种以发泡碱金属硅酸盐颗粒为基的成形体的制作方法。第一步是加热含水硅酸钠的颗粒状材料被加热使之发泡，随后将发泡的颗粒与水或硅酸钠水溶液一起喷射入铸模中，再进行热处理后形成成形体。
德国专利3246619描述了可发泡并可固化的铸模组合物及其生产方法，该组合物含有SiO2、其他氧化物，水和发泡剂如过硼酸盐。该专利还描述了其生产方法。根据德国专利2537492，硅酸盐泡沫颗粒与水玻璃、一种可控制水玻璃的固化的酸性化合物如氟硅酸钠或磷酸、一种疏水剂如聚乙基水合硅氧烷混合，使硅酸盐泡沫颗粒被固化成成形体。
用上述已知的方法以发泡碱金属硅酸盐颗粒为基制成的成形体，其缺点是在高大气湿度环境中尺寸稳定性不好。尤其是在高温和高大气温度的环境中，它往往失去原有的强度。这将导致在这样的环境中（高温高湿）长时间存放后，发泡碱金属硅酸盐颗粒之间的结合力大大地降低了。
因此，本发明的一个目的是开发这样一种方法，用该方法生产的成形体没有以上所述的缺点。
上述目的可用下述方法来达到：该方法是一种隔热性成形体的制作方法，所述的成形体具有隔热性并且是以发泡碱金属硅酸盐颗粒为基，该发泡碱金属硅酸盐颗粒含有二氧化硅（SiO2）和碱金属氧化物（M2O）（M是一种碱金属），其中SiO2和M2O的摩尔比为2～4.5，该方法包括：
a）将100重量份的发泡碱金属硅酸盐颗粒与单铝磷酸盐（Al（H2PO4）3）水溶液混合，并使混合物中硅与铝的摩尔比（Si：Al）为1～60;
b）将上述混合物置入预先选好的模具中，并冲压该混合物使其形成占混合物的原体积的20%～80%的成形体。
c）加热上述的成形体至温度为100～500℃，以使碱金属硅酸盐颗粒与单铝磷酸盐（Al（H2PO4）3）之间发生化学反应以形成化学键。
本发明中，发泡碱金属硅酸盐颗粒构成了成形体的主要成分。在其生产过程中，按照众所周知的方法，预先制备一种碱金属硅酸盐混合物，该混合物包含SiO2和M2O（M是一种碱金属），二者的摩尔比为2～4.5，优选为3.5～3.9。这种混合物可按下述方法得到，例如：把硅酸钠或硅酸钾水溶液（水玻璃）与无定形的二氧化硅混合。二氧化硅的来源并不重要。沉淀或热加工所得的硅石、甚至SiO2含量高的自然界硅酸盐均可使用。也可加入其他添加材料如固化水玻璃的酸性化合物和/或有机硅化合物，但这并不是必需的。发泡碱金属硅酸盐颗粒的生产是通过对上述混合物在100～500℃的温度进行热处理而进行的。如果混合物以颗粒状的形式与热蒸汽或热表面接触，则形成几乎为球状的多孔的碱金属硅酸盐颗粒。
为了生产本发明的成形体，优选是使用直径为0.1～20mm的发泡碱金属硅酸盐颗粒，特别优选的是使用直径为2～6mm的发泡碱金属硅酸盐颗粒。所用颗粒的堆积密度为10～150g/l，优选为30～50g/l，压缩50%时抗压强度为0.1～3N/mm2，优选是0.8～1.2N/mm2，孔的平均直径是50～1000μm，优选是150～200μm，BET表面积为0.01～5m2/g，优选是0.5～1m2/g。
上述发泡碱金属硅酸盐颗粒的水性泥浆状物具有很强的碱性。如果将2克碱金属硅酸盐颗粒研磨、悬浮于50ml水中并在沸点温度保持30分钟，冷却之后的泥浆用玻璃电极测得的pH值在10.0～11.5范围内。甚至在按照本发明，将相应数量的酸性单铝磷酸盐溶液加入到泥浆中后，再加热30分钟，其pH值依然在9.0～10.5的范围内。
从文献中已知，单铝磷酸盐在碱性环境中作为硅质材料的粘合剂是不合适的（T.Chvatal in Sprechsaal 108.（1975），p·585）。但是如果按本发明所给出的方法，在与一种水溶液混合并经进一步处理之后，你会惊奇地发现上述碱金属硅酸盐颗粒可以经热处理而形成稳定的成形体。尤为惊奇的是：按本发明的方法生产的成形体在尺寸稳定性和强度稳定性方面大大优于按现有的方法生产的成形体。碱金属硅酸盐颗粒与单铝磷酸盐水溶液的混合优选是按下述方法进行：把溶液喷洒到运动着的颗粒上，这样颗粒就被均匀地喷湿。水溶液中单铝磷酸盐的含量与碱金属硅酸盐颗粒的量应该相互匹配，以使得混合物中Si：Al摩尔比在1～60的范围内，优选是在12～20的范围内。特别优选的是，水溶液中单铝磷酸盐的含量为5～60%（重量）。
在单铝磷酸盐水溶液中，可以混悬有30重量份的遮光剂（以所使用的碱金属硅酸盐颗粒的用量为100重量份计）。所使用的遮光剂可以是无机氧化物、混合氧化物、碳化物、氮化物或碳。优选用钛铁矿，钛、铁、铬和锆的氧化物，也可选用碳化硅、碳黑和这些特定材料的混合物。
在将发泡碱金属硅酸盐颗粒与单铝磷酸盐溶液混合之后，将混合物置入横具之中，然后加压，使其形成体积为原体积的20～80%的成形体。在加压期间，混合物所夹带的气体可通过模具而逸出。优选使用那些能形成板状、形体状或管状成形体的模具。此外，当然也可以使用能制造出形状结构更复杂的成形体的模具。
随后在100～500℃的温度对成形体进行热处理步骤。虽然并不是一定需要，但一般是首先将成形体与模具相互分离开来，而仅仅是将成形体进行热处理。如果加热时产生的水蒸汽能逸出的话，那么热处理可以在模具内进行。根据成形体的几何形状和体积不同，优选是在以上所述的一个适当的温度范围内加热10分钟到4小时。但所选择的这个温度应至少能使碱金属硅酸盐颗粒与单铝磷酸盐发生化学反应而形成化学键。
传热可以对流、热辐射、热传导或微波辐射的方式来进行。化学反应键的形成可用红外线光谱监测和确认。热处理的实施可以分批地进行（非连续的），脉冲式进行（部分连续地）或用传送带进行（连续地）。
热处理之后，成形体的密度为0.050～0.2g/cm3，优选是0.070～0.1g/cm3。
按本发明生产的成形体，根据其各自不同的密度而分别具有不同的导热性，其在23℃时的导热率在0.030～0.1W/mK的范围内，因此它是非常合适的隔热材料。由于其强度高，所以对其进行锯、磨、切割、锉或钻孔等机械加工是不成问题的。该成形体的特别的优点是在高大气湿度环境中，具有优良的尺寸稳定性和强度稳定性。在相对湿度为95%、温度为50℃的空调潮湿房间中24小时后，依据德国工业标准DIN53421测得其抗压强度范围为0.01～0.1N/mm2，依据DIN53452测得的抗挠强度范围为0.01～0.1N/mm2。
纸或胶片，例如牛皮纸、铝箔、纸板-灰胶纸柏板、金属片、增强的塑料胶片或纺织玻璃纤维布均可用合适的粘合剂粘贴在成形体的表面，所使用的胶粘剂例如可以是水玻璃或有机接触（organic contact）粘接剂。同样地，成形体也可以具有一密封的涂层（closed coatings），例如用合成有机聚合物或交联的硅树脂溶液进行浸涂或喷涂。最后，隔热成形体也可采用气密包装，覆盖物内的压力应低于大气压，优选是低于10毫巴（mbar），以便增加成形体的隔热性能。
本发明生产的成形体优选是作为建筑物中的隔热材料来使用。例如：用作楼顶或墙体的隔离层，或用作室内装修如悬吊天花板或设置隔离墙。因为它们不易燃，受热时不产生有害气体，而且还不含有对人体有害的无机纤维。此外，该成形体作为一种隔热材料也可应用于制冷工程和温度高达400℃左右的热力工程。还可进一步用于隔音。
通过下述实施例及比较实施例来进一步说明本发明的成形体所具有的优良的尺寸稳定性。
实施例：
将60g发泡硅酸钠颗粒，其SiO2：Na2O摩尔比为3.67，颗粒直径约为3mm，堆积密度为37g/l，压缩至50%时的抗压强度为1.0N/mm2，孔直径约为180μm，BET表面积为0.9m2/g，与36g浓度为50%（重量）的强Al（H2PO4）3水溶液（FFB 32i，从法兰克福的 CHE METALL GmbH得到）混合并使其均匀湿化，使混合物中Si：Al的摩尔比为13.9。将上述混合物置入一个边长为200mm的正方形模具中，并将其加压直到得到一块厚20mm的模板。然后将模板在300℃的温度加热处理1小时，在此期间，模板内部物质的IR光谱发生变化。冷却之后，成形体密度为0.104g/cm3，依据DIN53421测得的抗压强度为0.14N/mm2，依据DIN53452测得的抗挠强度为0.10N/mm2，导热率的值为0.0457W/mK（采用从兰根的HESTO公司得到的HESTO-Lambda-CONTROL A50 instrument进行测试）。
在将温度控制为50℃、相对空气湿度控制为95%的空调房间内存放48小时后，受潮的模板的抗压强度仍然为0.03N/mm2，其抗挠强度仍然为0.03N/mm2。
比较实施例：
将实施例中的60g发泡硅酸钠颗粒用36g水，而不是实施例中的Al（H2PO4）3水溶液，进行喷洒。然后用与上述相同的工序对其进行进一步的处理。
在将温度控制为50℃、相对空气湿度控制为95%的空调房间内存放48小时后，模板不再是无损的，该模板也不能进行抗压强度及抗挠强度的测定。
