Description
技术领域
本发明涉及新能源利用玻璃技术领域，具体涉及一种超白玻璃基板的制备工艺。
背景技术
超白玻璃一种超透明低铁玻璃。超白玻璃制成的挡板是线聚焦式太阳能集热系统二次反射镜部分的关键部件，其主要作用是有效减少集热管的对流与辐射散热损失。但由于玻璃挡板表面对太阳光的反射作用将降低太阳能镜场阵列(一次反射镜)反射光进入二次反射镜的透光效率。而且进入二次反射镜的太 阳光已通过一次反射镜进行了聚光(聚光比：10~50)，因此玻璃基板表面对进入二次反射镜太阳光的反射作用将显著降低太阳能集热场的镜场效率。现有的超白玻璃在具体使用过程中，尤其在户外环境中使用的时候，通常存在透光率低，抗反射能力差，表面容易粘附灰尘等情况，影响超白玻璃表面的正常使用功能。
为了克服上述现有技术的缺陷，本发明提供一种超白玻璃基板的制备工艺，通过该工艺对现有超白玻璃进行合理改进设计，在保证超白玻璃透光效率以及透明度的同时，还能够通过抗反射膜有效降低集热管的红外辐射热损失，并且提高集热管表面的超疏水特性，进而有效解决现有技术存在的不足和缺陷。
发明内容
本发明的目的就在于：针对目前存在的上述问题，提供一种超白玻璃基板的制备工艺，通过该工艺对现有超白玻璃进行合理改进设计，在保证超白玻璃透光效率以及透明度的同时，还能够通过抗反射膜有效降低集热管的红外辐射热损失，并且提高集热管表面的超疏水特性，进而有效解决现有技术存在的不足和缺陷。
为了实现上述目的，本发明采用的技术方案是：
一种超白玻璃基板的制备工艺，所用的原料按照质量份数的配比为：氟化物700份，硫酸盐30~60份，二氧化钛120~150份，氯酸盐60~80份，酸性物50~70份，二氧化硫尿15~30份，高岭土60~80份，稳定剂60~100份，膨润土50~80份；并将上述原料配制成蒙砂液；将玻璃基板通过蒙砂液浸泡处理之后，在蒙砂处理的粗糙表面镀抗反射膜，再在抗反射膜的表面镀增透膜，所述增透膜的表面涂覆透明超疏水涂层。通过上述蒙砂液处理之后，玻璃基板表面的粗糙度可以达到200nm~300nm，此时通过在超白玻璃基板表面镀抗反射膜，具有较好的抗红外反射效果。经过近期发明人的具体研究结论得出，当超白玻璃基板表面的粗糙度介于200nm~300nm之间时，结合抗反射膜的填充以及涂覆作用，可以使玻璃基板表面的抗反射效率得到有效提高，并且保持抗反射率为95%以上。
优选的，所述氟化物包括氟化氢铵、氟化氢钠以及氟化氢镍中的至少一种。
优选的，所述硫酸盐包括硫酸铵、硫酸钠、硫酸镍、硫酸锌以及聚合硫酸铁中的至少一种；所述氯酸盐包括氯化镁以及氯化铵中的至少一种。
优选的，所述酸性物包括水杨酸、草酸以及氨基磺酸中的至少一种。
优选的，所述蒙砂液的配制步骤为：将准备1000份的清水，向其中加入氟化物700份、硫酸盐30~60份、二氧化钛120~150份并混合搅拌10min,使原料混合均匀；然后再将氯酸盐60~80份，酸性物50~70份，二氧化硫尿15~30份，高岭土60~80份，稳定剂60~100份，膨润土50~80份加入到上述混合物中，搅拌5min；最后再向其中加入稳定剂60~100份，形成蒙砂液。
优选的，所述抗反射膜为Nb、Cu、Al、Ti、Ag或Au 金属薄膜中的一种或者多种金属膜的层叠膜；所述抗反射膜的厚度为0.5μm~1μm。
优选的，所述增透膜为厚度50nm~200nm的多层膜；所述增透膜为氟化镁、氟化钙、硫化铅以及硒化铅从下往上依次层叠形成的薄膜。
优选的，所述抗反射膜为厚度100nm~500nm的多层膜，所述抗反射膜从内到外依次为氧化锌膜、二氧化钛膜、二氧化硅膜及氮化硅膜层叠形成。
优选的，所述透明超疏水涂层为纳米二氧化硅超疏水涂层；所述透明超疏水涂层的厚度为1μm~2μm。
由于采用了上述技术方案，本发明的有益效果是：
首先，本方案通过在玻璃基底表面进行前期的蒙砂处理，使玻璃表面形成一层粗糙结构；再通过在玻璃外表面增加增透膜，可使超白 玻璃玻璃的透射率增加至约98％，利于提高太阳能集热场的镜场效率。通过在玻璃基板的内表面增加抗反射膜，可使超白玻璃基板的红外反射率达到约95％，显著提高集热管的光热转化效率。
其次，通过在玻璃基板表面构建透明超疏水涂层，利于有效保证玻璃基板表面的超疏水特性。众所周知，在超疏水表面存在极低的表面粘附力，致使超疏水表面水滴不容易粘附在其表面，容易滚落；同时，根据相关科学研究报道，灰尘难以在超疏水表面粘附，使超疏水表面的灰尘容易脱附，进而使超疏水表面具备较好的自清洁效果以及抗污防尘效果，从而有效避免户外灰尘粘附堆积而影响超白玻璃的整体透明性以及正常的使用功能。
再一方面，本发明的制备工艺相对不是特别复杂，形成的多层结构使玻璃表面的总体性能得到有效增强，具有较好的实用价值及推广价值。
