技术领域
本发明涉及陶板生产技术领域，更具体地说，本发明涉及一种窑变烧结陶板及其制备方法。
背景技术
由于幕墙陶板优异的保温隔热性能和美观的外表，目前已被广泛应用于多种建筑领域，如标准工业厂房、通讯机房的墙面板、大型商场、高层民用建筑、办公楼的外保温隔热幕墙板等。随着陶板的应用范围和领域越来越广泛，人们不仅对陶板作为幕墙的保温隔热、防风以及防尘等性能有很高要求，对其外观的要求也是与日俱增，陶板采用黏土烧制，一般的粘土都由硅酸盐矿物在地球表面风化后形成，一般在原地风化，颗粒较大而成分接近原来的石块的，称为原生黏土或者是一次黏土，这种黏土的成分主要为氧化硅与氧化铝，色白而耐火，为配制瓷土之主要原料。
但是其在实际使用时，仍旧存在较多缺点，如陶板的整体重量较大，陶板安装稳定性不强，影响陶板的使用。
发明内容

陶板主体坯料中混合木炭粉，在陶板烧制时，木炭粉燃烧，使陶板主体内形成均匀的气孔，缓冲泥板在烧制过程中产生的剧烈收缩，线性热膨胀稳定，从而防止泥板烧裂。
一种窑变烧结陶板的制备方法，其特征在于：具体包括如下操作步骤：
步骤一：制备陶板主体，按重量份数计取黏土60～66份、高岭土12～14份、木炭粉1～2份，通过搅拌机均匀搅拌，通过模具冲压得到陶板主体坯料，陶板主体坯料内部冲压形成空腔；

步骤三：制备陶板下层，按重量份数计取黏土30～34份、高岭土6～8份、碎瓷片28～34份，通过搅拌机均匀搅拌，通过模具冲压得到板状陶板下层坯料，板状陶板下层坯料底端面冲压形成棱槽；
步骤四：将得到的陶板上层坯料、陶板主体坯料和陶板下层坯料自上而下依次叠放，再次冲压形成陶板坯体，并在陶板主体坯料顶端涂釉；

（2）本发明通过在陶板主体坯料中混合木炭粉，在陶板烧制时，木炭粉燃烧，使陶板主体内形成均匀的气孔，缓冲泥板在烧制过程中产生的剧烈收缩，线性热膨胀稳定，从而防止泥板烧裂，配合模具冲压产生的空腔，方便烧制过程中的气体排出，提高窑变烧结成品率。
