Description

一种硅藻土基轻质环保陶瓷砖的制备方法
技术领域
本发明涉及陶瓷的制备方法，特别是涉及一种硅藻土基轻质环保陶瓷砖的制备方法。
背景技术
硅藻土是古代单细胞低等植物硅藻遗体堆积后，经过一定的地质条件下成岩作用而形成的一种具有多孔性的生物沉积岩，是由硅藻死亡以后的遗骸沉积形成的，主要矿物成分是蛋白石及其变种，化学成分主要是SiO2，并含有少量的Al2O3、Fe2O3、CaO、Na2O、MgO等和有机质等杂质。这些杂质夹杂在硅藻壳间，填充于硅藻壳的孔隙中，或附着于壳表面。硅藻体形微小，一般为几微米到几十微米。硅藻土的颜色为白色、灰白色、灰色和浅灰褐色等。硅藻壁壳上有多级、大量、有序排列的微孔结构，使得硅藻土具有许多优异的特殊性能。质量轻，我国硅藻土密度在1.9～2.3g/cm3，堆密度在0.34～0.65g/cm3，比表面积大，一般为19～65cm2/g；孔隙率高，孔半径范围为50～800nm，孔体积为0.45～0.98cm3/g；吸附液体能力强，一般可吸收自身重量1.5～4倍的水量和1.1～1.5倍的油分；化学稳定性高，不溶于盐酸，易溶于碱；熔点高达1400～1650℃，具有相对不可压缩性、质软、隔音、耐磨、耐热等诸多优异性能，因此硅藻土在国内外已经得到了广泛的开发与应用，市场应用前景无限广阔。
以多微孔质硅藻土为原料的环保型室内装修材料，如硅藻土涂料、壁纸、板材及砖材等，在国外特别是日本等国越来越受到消费者的青睐和喜爱。但是，硅藻土环保饰材目前在国内还没有得到大量的推广应用，相关方面的技术研究也才刚刚起步。其制备工艺相对简单，制备得到的产品因引入大量硅 藻土易出现现制品裂纹和烧成收缩率过大等问题，这些技术问题也成为硅藻土作为新型建材材料的一个瓶颈和限制所在。
发明内容
为了解决制备得到的产品因引入大量硅藻土易出现现制品裂纹和烧成收缩率过大等问题，本发明提供一种硅藻土基轻质环保陶瓷砖的制备方法。
本发明的目的是通过以下措施来达到：一种硅藻土基轻质环保陶瓷砖的制备方法，按照如下步骤制备：首先将助熔剂以料球比1∶2装入球磨罐中，用干法球磨混合5～6h；将混合均匀的助熔剂加入硅藻土原料中，并以料球比1∶2装入球磨罐中，采用干法球磨混合60min制得硅藻土混合料。再在硅藻土混合料中加入占混合料质量3％～5％的水玻璃及适量水的混合液，搅拌混合均匀后在SAC型外圆定位锤击式坯体试样压制机上进行压制成型。坯料成型后，对其进行干燥、烧成。
一优选方案为：所述过程中助熔剂为叶腊石、锂辉石、钠长石以及滑石等按照一定比例配制而成，其优选质量比为2:3：3:2。。
一优选方案为：所述过程中助熔剂与硅藻土的质量比为1:20～30。
一优选方案为：所述过程中成型剂选用水玻璃与水的混合液，其中水玻璃(模数为1.8～3)的质量分数为55％～60％。
一优选方案为：所述产品的烧成制度为：室温～180℃升温时间6min，180～350℃升温时间12min，350～950℃升温时间30min，950～1050℃升温时间8min，1050℃保温40min，1050～800℃随炉降温，800～300℃开炉降温，300℃～室温随炉降温。
有益效果：本发明制备的硅藻土基轻质环保陶瓷砖，因助熔剂及成型剂的选配，使其具有吸水率高、开口微孔隙率高、抗弯强度高等优点，且耐高温、使用寿命长。同时该方法工艺简单、工艺过程易于控制，有利于工业化的实现，具有广阔的商业和市场前景。
