Abstract

本发明属于建筑陶瓷技术领域,具体涉及一种薄型瓷砖及其制备工艺。其坯体配方的重量百分比组成为:高铝土19~24%、黑泥6~12%、白泥条20~24%、锂长石5~8%、钾钠长石10~15%、钠长石20~25%、滑石2~4%、增韧剂4~8%、坯体增强剂0.5~1%、促进剂0~1%。本发明通过优化坯体配方和粉料颗粒级配以提高成型后的生坯强度,并结合窑炉的烧成制度来提高烧成后的成品强度,以减少因厚度降低带来的断坯、断砖问题,兼具轻薄的同时,还具有吸水率低、强度高、韧性好等特点;同时厚度降低可以减少天然矿物等不可再生资源及能源的消耗、降低建筑物的载荷,符合国家“节能降耗”的总体方针政策。

Description

一种薄型瓷砖及其制备工艺
技术领域
本发明属于建筑陶瓷技术领域,具体涉及一种薄型瓷砖及其制备工艺。
背景技术
建筑陶瓷是一个典型的高能耗、高污染和高资源消耗型行业,给社会的资源和能源消费带来很大的压力。无论从原材料使用量、到生产过程中的能源消耗,薄型建筑陶瓷砖(板)都能很好地实现“节材”“节能”的低碳目标。薄型瓷砖由于坯体厚度减薄,如果采用一般的陶瓷坯料配方,生坯和成品强度不能满足要求,易出现破碎等问题。因此,陶瓷砖的薄型化生产首先要在原料选择和配方设计方面考虑陶瓷砖的增强和增韧技术。
发明内容
针对上述问题,本发明在原料选择和配方设计方面考虑提高陶瓷砖的强度和韧性,提供了一种强度高和韧性好的薄型瓷砖及其制备工艺。
为了实现上述目的,本发明采用的技术方案如下:

C.除铁:将球磨后的浆料泄浆,过振动筛后经除铁机除铁,泥浆入中转池中陈腐12小时备用;
D.制粉:将经步骤C得到的泥浆经喷雾干燥塔干燥制成粉料,粉料含水率4.8% ~ 6.6%,再将所得粉料入储粉桶陈腐24h备用;
E.成型:将步骤D中得到的粉料经压机压制成型;
F.干燥:坯体入干燥窑干燥,干燥后坯体含水率≤0.5%;
G.烧成:坯体入辊道窑烧成,烧成周期50~60min,烧成温度1195~1226℃。
