Description
本发明涉及一种用于将基于二氧化钛的光催化涂层无粘合剂地施涂到载体材料上的方法。
此外本发明涉及涂层的用途。
基于二氧化钛的光催化涂层对于多种技术应用领域具有重大的经济意义。重要的应用领域例如为制造住宅建筑中的玻璃和玻璃元件上的涂层或者汽车工业的制品用于在不同的载体材料的情况下生产超疏水性层。在制备具有高浓度二氧化钛的高活性光催化层的情况下不利的是,涂层缺乏机械稳定性。
对于二氧化钛涂层,已知的是施涂二氧化钛在挥发性溶剂例如甲醇中的悬浮液,并且随后在高温环境中烧结所述层。然而在该方法中仅可以产生具有低耐磨强度的机械不稳定的层,由此大大限制了使用领域并且必须定期更新涂层。
例如,由K.Amini,“Manufacturing dye-sensitized solar cells”已知一种涂层方法,其中将二氧化钛悬浮液作为涂层喷雾到太阳能电池上并且烧结。
为了生产持久并稳定的层的已知方法在于混入粘合剂例如水玻璃或硅氧烷。在此,不利的是,二氧化钛颗粒被所使用的粘合剂包裹并且由此光催化的涂层仅有限地起效。
此外,根据DE 10 2014 100 385 A1已知用于沉积基材的功能层的等离子体涂层方法和用于实施所述方法的装置。在此,使用大气等离子体,以及惰性载气,从而,一方面可以带来非常高的能量来在涂层材料中启动化学反应,另一方面可实现在排除空气中的氧的情况下在等离子体中的可控的化学反应。用于形成功能层的涂层材料经由供料在排除氧的情况下直接输送到在喷嘴中产生的等离子体中。
由此,可以产生非常稳定的平坦平面,但是其具有低光催化活性,因为该表面具有非常低的孔隙度。
本发明的目的在于,改善开篇提及类型的方法。此外,本发明的目的在于改善开篇提及类型的用途。
该目的所涉及的方法根据本发明通过具有权利要求1中所提及的特征的方法解决。该目的所涉及的用途根据本发明通过权利要求9中所提及的特征解决。
本发明的有利实施方案是从属权利要求的主题。
用该方法将基于液体,优选水的二氧化钛悬浮液作为细溶胶喷雾到热载体上。在此,液体快速蒸发并且二氧化钛悬浮液的二氧化钛颗粒快速烧结到载体材料上。
用该方法生产的二氧化钛层在高表面质量的同时具有高表面均匀性。相比迄今所使用的方法,将实现有效得多的光催化效果并达到高机械稳定性,特别是提供高耐磨性。令人惊讶地证实,如此所获得的二氧化钛层不仅自身稳定,特别是不可擦拭,而且特别好地粘附在载体材料上。所产生的层具有高的孔隙度,从而待处理的物质可以深入所述材料中。用所述方法产生的二氧化钛层因此特别好地适合作为多孔的并且同时稳定的层用于催化剂,用该催化剂可实现有害物质有效并快速分解。
由于悬浮液不含粘合剂,因此,光催化活性的颗粒不被粘合剂包裹。由此,相比迄今所使用的方法,实现快速并温和的涂布。
该方法的特征在于一系列优点,包括:
-省略了用于烧结的分开的加工步骤。由此,还产生星状晶体(四方锐钛矿晶体,也称为八面石)转化为金红石(经常出现的由“氧化物和氢氧化物”的矿物类构成的矿物)减少。该矿物结晶为具有化学组成TiO2的四方晶体体系,并且主要发展短棱镜至长棱镜、垂直带条晶体并且非常经常的以多合成、层状或环状的三胞、四胞和六胞形式的晶体双生体,以及颗粒至团块矿物-聚集体。
-光催化涂层的效率较高。
-可以非常精确地调节层厚度并且精细分级。
-通过快速蒸发产生多孔层,由此可以将有害物质较好地引入光催化层中,因此实现有害物质有效并快速地分解。
-所述方法可以自动进行。
-所施加的层机械稳定并耐冲洗。
-所述方法可以用于所有的直至特定的温度是稳定的载体材料。
-所述方法节约资源,因为仅使用少量二氧化钛。
所述方法的有利实施方案使用由水和份额为5至20质量%的二氧化钛颗粒构成的二氧化钛悬浮液。
因此,可以实现具有高机械强度的品质上高级的、均匀的层。
有利地使所述载体在喷雾期间达到高于载液的沸点的温度。在根据本发明使用水作为载液的情况下,温度为150至250℃。由此确保短加工时间和高效率。
在本发明的方法的有利实施方案中,通过电流流过载体材料而在载体中自身产生热。由此,还可以进一步提高涂层的品质,因为在涂覆过程期间载体温度可以保持恒定。
用该方法产生的涂层的特征在于一系列优点,包括:
-可达到的层厚度和层结合不再取决于加工速度,由此,还可以产生大面积的催化剂;
-通过精确调节温度,固化过程可以在最优条件发生,而无晶体中不受控地改性,这实现了较好的可调节性。
在涂覆不锈钢以及钝化的金属的情况下,特别是在钛的情况下,提供了另外的优点,如良好的化学耐腐蚀性以及由于低导电性而造成的高电阻用于容易地电加热以及高反射能力以较好地利用处于较深的催化剂层。
根据本发明的方法制备的在载体材料上的基于二氧化钛的涂层的用途根据本发明用于催化剂用于有害物质的分解。
以下详细阐释本发明的实施例。
该实施例阐释了由细网格化金属格栅构成的载体材料的涂层。这类格栅非常良好地适合用于处理流经的气体和液体,例如空气净化和水净化。
所述格栅由不锈钢线制成的网构成。网格宽为0.25mm并且线直径为0.16mm。金属格栅为矩形并且织在两个相对的侧上,其中电流流过所述格栅,由此所述金属格栅被加热到约200℃的温度。用商业上常规的喷枪将由水和二氧化钛粉末构成的二氧化钛悬浮液作为细溶胶喷雾到热金属格栅上。在此,水被快速蒸发并且留下的二氧化钛粉末在烧结工艺中与载体材料结合。由此在载体材料上产生均匀的二氧化钛层。重复喷雾直至达到希望的层厚度。以此方式可以产生具有高机械强度的0.5至40g/m2的层厚度。
