Abstract
本发明公开了一种多孔陶瓷，该发明是由碳化硅藻土，活性炭，粘土，造孔剂，水混合制备而成。本发明的多孔陶瓷，主要以硅藻土，活性炭，黏土为主要原材料，大大降低了多孔陶瓷的生产成本，并添加适量复配的造孔剂，在保证造孔量的较多的情况下，多孔陶瓷的吸水率和气孔率逐渐升高，而且不会引起体积密度和抗折强度的下降。
Description
技术领域
本发明涉及化工领域，具体涉及一种多孔陶瓷。
背景技术
多孔陶瓷是一种含有气孔的固体材料，一般来说，气孔在多孔陶瓷体中所占的体积分数在20%到95%之间。多孔陶瓷作为固液分离介质、液体的过滤净化、气体净化以及化学反应的催化剂载体等广泛应用在环保、化工、冶金医药及生物医学等领域。
硅藻土是由统称为硅藻的单细胞藻类死亡以后的硅酸盐遗骸形成的,其本质是含水的非晶质SiO2，因其具有巨大的比表面、强大的吸附性以及表面电性等特点,在污水处理、各种填料、涂料添加剂等场合得到广泛应用。硅藻土来源广泛，价格低廉，本身就具有大量微孔，是制备多孔陶瓷的理想原料。
发明内容
本发明目的在于，提供一种多孔陶瓷，本发明采用的技术方案如下：
一种多孔陶瓷，其特征在于，由以下组分按重量百分比混合制备而成：
碳化硅藻土 45-65份
活性炭 5-20份
粘土 10-20份
造孔剂 5-15份
水 5-30份。
进一步地，所述的碳化硅藻土粒径在300-500目。
进一步地，所述的碳化硅藻土是经酸洗后，于氮气保护下在800-1000℃高温碳化处理。
进一步地，所述的造孔剂是由淀粉与煤粉按照重量比为1:1混合组成。
本发明相对于现有技术的有益效果是：本发明的多孔陶瓷，主要以硅藻土，活性炭，黏土为主要原材料，大大降低了多孔陶瓷的生产成本，并添加适量复配的造孔剂，在保证造孔量的较多的情况下，多孔陶瓷的吸水率和气孔率逐渐升高，而且不会引起体积密度和抗折强度的下降。
具体实施方式
以下将结合实施例对本发明的构思及产生的技术效果进行清楚、完整地描述，以充分地理解本发明的目的、特征和效果。显然，所描述的实施例只是本发明的一部分实施例，而不是全部实施例，基于本发明的实施例，本领域的技术人员在不付出创造性劳动的前提下所获得的其他实施例，均属于本发明保护的范围。
实施例1：一种多孔陶瓷，其特征在于，由以下组分按重量百分比混合制备而成：

实施例2：一种多孔陶瓷，其特征在于，由以下组分按重量百分比混合制备而成：
碳化硅藻土 58份
活性炭 8份
粘土 12份
造孔剂 7份
水 15份。
以上对本发明的较佳实施方式进行了具体说明，但本发明创造并不限于所述实施例，熟悉本领域的技术人员在不违背本发明精神的前提下还可作出种种的等同变型或替换，这些等同的变型或替换均包含在本申请权利要求所限定的范围内。
