Description

一种比表面积大的多孔陶瓷及其制备方法
技术领域
本发明涉及陶瓷领域，具体是一种比表面积大的多孔陶瓷。
背景技术
陶瓷是用陶土和瓷土这两种不同性质的粘土为原料，经过配料、成型、干燥、焙烧等工艺流程制成的器物。瓷业是我国的传统工业，陶瓷产品是我国轻工行业的支柱产业和出口拳头产品。陶瓷产品不仅仅有日用陶瓷，工业陶瓷的种类也很多，多孔陶瓷就是工业陶瓷的其中一种。
多孔陶瓷材料是以刚玉砂、碳化硅、堇青石等优质原料为主料、经过成型和特殊高温烧结工艺制备的，多孔陶瓷多用于各种介质的精密过滤与分离、高压气体排气消音、气体分布及电解隔膜等。但是现有的多孔陶瓷的孔隙率还达不到人们的预期，人们在用多孔陶瓷当作滤芯时，滤芯的更换周期较短，人们更换滤芯的次数频繁，这就为人们的使用带来了不便。
发明内容
本发明的目的在于提供一种比表面积大的多孔陶瓷，以解决上述背景技术中提出的问题。
为实现上述目的，本发明提供如下技术方案：
一种比表面积大的多孔陶瓷，包括以下重量法的原料：酚醛树脂3-8份、氧化铝2.4-5份、硼砂8-18份、方解石10-16份、钠闪石16-25份、陶土75-83份、锌镁合金粉0.6-1.3份、石墨2-4份、晶须0.8-1.4份、氧化铬1-2份、苯酚6-10份、纳米二氧化硅4-6份、表面活性剂2-5份和芋头3-10份。
作为本发明进一步的方案：晶须采用碳化硅、硫酸钙、碳酸钙、氧化锌和硼酸铝中的至少一种，晶须的长度为1-3厘米。
作为本发明进一步的方案：该多孔陶瓷还包括竹炭纤维1.6-3.5份。
所述比表面积大的多孔陶瓷的制备方法，具体步骤如下：
步骤一，将锌镁合金粉加入过量的盐酸溶液中，并不断地磁力搅拌，待锌镁合金粉完全溶解时用去离子水洗涤，然后置于氢氟酸溶液中搅拌60-90分钟，再用去离子水多次洗涤，真空干燥4-8小时，干燥温度为70-86摄氏度，再置于分散剂中分散，磁力搅拌1-3个小时，得到分散液；
步骤二，将苯酚加入到质量分数为50-65%的乙醇溶液中，再加入一定量的氨水，在25-28摄氏度的恒温条件下搅拌10-30分钟，待苯酚全部溶解后加入表面活性剂，继续在25-28摄氏度的恒温条件搅拌20-45分钟，然后加入过量的甲醛溶液，在25-28摄氏度的恒温条件搅拌12-15小时，将溶液转移至高压反应釜，在65-84摄氏度下进行水热反应，待反应结束后自然冷却至室温，离心洗涤分离冷冻干燥后获得第一产物；
步骤三，将芋头粉碎成碎屑，再将芋头碎屑放进玻璃容器内并加入质量分数为26-30%的盐酸浸没，加热至90-95摄氏度并且保持30-40秒，快速降温后过滤分离，得到盐酸混合溶液，将盐酸混和溶液减压低温浓缩至稀稠，然后加入质量分数为90-95%的乙醇溶液稀释，并不断搅拌，稍作静置产生芋头果胶沉淀，将玻璃容器上层的酒精过滤倒掉，再次加入等量酒精稀释、搅拌、过滤和沉淀，得到芋头果胶；
步骤四，将石墨粉碎至3-8um，然后将石墨粉倒入分散液中进行搅拌，得到第二产物；
步骤五，将酚醛树脂、氧化铝、硼砂、方解石、钠闪石、陶土、晶须、氧化铬和纳米二氧化硅进行球磨并且过240-300目筛子，得到第三产物；
步骤六，将第一产物、芋头果胶、第二产物和第三产物混合并且加入适量去离子水，混合成泥状，在惰性气氛下以3-6摄氏度/分钟的速率升温至640-680摄氏度并且保持5-8小时，再以10-15摄氏度/分钟的速率升温至960-1080摄氏度并且保温6-12小时，再用8-15摄氏度/分钟的速率降温至520摄氏度并且保温25-40分钟，最后再以3-5摄氏度/分钟的速率降温至120-150摄氏度，最后再进行炉冷，即可得到成品。
作为本发明进一步的方案：步骤五中球磨的球料比为6-9：1，球磨温度为36-45摄氏度。
与现有技术相比，本发明的有益效果是：本发明原料来源广泛，制备工艺简单，通过芋头果胶、多孔的稳定体系等物质相互作用，得到的陶瓷具有高的孔隙率，从而增大了陶瓷的比表面积，满足了人们的使用需求。
