进一步的,所述氧化锆改性滑石粉制备方法为:
(1)将滑石粉球磨粉碎至颗粒大小为500目后备用;
(2)对氧化锆进行分级粉碎操作,即先取氧化锆总质量的45%,将其球磨粉碎至颗粒大小为250目,然后将剩余的氧化锆磨粉碎至颗粒大小为500目,最后将其混合均匀得氧化锆粉末待用;
(3)将步骤(1)处理后的滑石粉与其质量5倍的清水混合后,调节其pH至8.5,然后加入滑石粉质量3.5%的月桂醇硫酸钠,搅拌均匀后,加热至65℃,继续搅拌30min,得到滑石粉分散液;
(4)将步骤(2)中得到的氧化锆粉末与滑石粉分散液按150g:300mL的比例均匀混合到一起,再添加氧化锆粉末质量0.1%的高锰酸钾,加热至60℃,进行研磨2小时,然后进行过滤,真空干燥至恒重,即得。

进一步的,所述步骤(4)中真空干燥温度为200℃。
进一步的,所述电石渣粒度为300目,所述电石渣经过有机酸溶液进行酸洗处理。
进一步的,所述电石渣经过有机酸溶液进行酸洗为将电石渣与质量分数为1.2%的乙二酸溶液按50g:220mL的比例混合浸泡2小时,然后过滤,烘干至恒重,即得。
进一步的,所述活性炭为椰壳活性炭。
本发明相比现有技术具有以下优点:本发明制备的耐磨瓷砖采用多种纯天然的矿物质成分,通过添加可塑性与耐火性良好的硅藻土与电石渣进行混合,然后再结合氧化锆改性滑石粉的作用,能够有效的提高原料的分散均匀性,氧化锆改性滑石粉,能够有效的改善原滑石粉的结构特性,使得改性后的滑石粉在瓷砖体系中均匀分散在瓷砖内部,在瓷砖进行烧结过程中,能够有效的促进瓷砖的烧结,提高瓷砖内部结构的紧密程度,促进原料成分之间的致密性,降低孔隙率,从而大幅度的提高了瓷砖的耐磨性;同时硬度相较于普通瓷砖提高了8%左右,并且耐磨性相较于普通瓷砖提高了10%左右;从材料来源讲,利用了石英砂、硅藻土、电石渣,材料易取,既经济又实惠;从环保方面讲,处理了建筑垃圾,美化了环境,变废为宝,极大的提高了资源的利用率,本发明耐磨瓷砖销售较普通环瓷砖的平均销量提高10.12%,经济收入提高13.25%。
