进一步的,高岭土、硅藻土、蒙脱石、石墨粉和淀粉三种主成分的搭配保证了多孔陶瓷的强度,石墨粉与淀粉双组份造孔剂使其获得较高的气孔率。
进一步的,通过对高岭土、硅藻土、蒙脱石、石墨粉和淀粉的粒径有效地控制多孔陶瓷的孔径。
进一步的,PVA的浓度为10%~20%,PVA的质量分数为7%~10%,具有较强的粘结效果。
进一步的,步骤S2烘干处理有效排除坯体中的水分。
进一步的,通过干压成型简单易成所需的形状。
进一步的,一次升温排除造孔剂,二次升温烧结成型。
进一步的,硅油浸液在多孔陶瓷表面形成一层硅油膜层。
进一步的,硅油浸液在多孔陶瓷内部通道中形成一层硅油膜层。
进一步的,烘干排除酒精,在中温炉中使得硅油膜生成一层均匀的氧化硅薄膜,提高了对烟油的吸收速率。
综上所述,本发明采用高岭土、硅藻土、蒙脱石为主要原料制备的多孔陶瓷,对其进行表面改性处理,使得多孔陶瓷表面性质变的亲油,且工艺简便易操作,原材料价格低廉,有效提升成本。

实施例6
S1、称取20um高岭土15份、20um硅藻土10份、20um蒙脱石3份、15um石墨粉10份、20um淀粉8份均匀混合后,加入20%浓度10%PVA搅拌均匀,通过30目筛网完成造粒;
S2、称取完成造粒的粉料,均匀摊铺在干压模具腔内,在50MPa下干压成型,而后在烘箱中保持80℃保温20h烘干处理;
S3、将烘干的陶瓷坯体置于烧结炉中,升温速率3℃/min升温至800℃保温3h,然后继续升温,升温速率8℃/min升温至1300℃,保温3h之后随炉冷制成多孔陶瓷;
S4、称取30份的羧基硅油和90份的无水乙醇将两者倒入烧杯后搅拌均匀制成硅油浸液,将多孔陶瓷浸泡在硅油浸液中,置于真空蒸发皿中,抽真空至0.08MPa以下,取出样品在烘箱中100℃保温10h烘干处理,之后放入中温炉控制温度1300℃保温5h制成电子烟多孔陶瓷。
由上述实施例获得的陶瓷随烧结温度的提高和保温时间的提升,陶瓷的强度获得提升,但气孔率随之下降,所以在使用本发明时合理控制温度尤为重要。
以上内容仅为说明本发明的技术思想,不能以此限定本发明的保护范围,凡是按照本发明提出的技术思想,在技术方案基础上所做的任何改动,均落入本发明权利要求书的保护范围之内。
