[根据细则37.2由ISA制定的发明名称]　玉质鱼肚白效果的陶瓷板、坯料、制备方法及用途 技术领域
本发明涉及陶瓷板技术领域，尤其涉及一种玉质鱼肚白效果的陶瓷板、坯料、制备方法及用途。
背景技术
陶瓷大板和岩板成为现如今陶瓷行业高端制造的趋势。目前市场上常见的大规格白色陶瓷岩板其坯体白度基本在65度以内，偶尔也能看到坯体白度有70度的白色岩板，但几乎都是小规格岩板(900㎜*1800㎜规格以内)，这是由于很多超白坯料的干燥强度不够，成型性能不好，压大规格砖容易在制造过程中出现破损，导致烂砖现象；同时，陶瓷的通体装饰较生硬，坯胎白度、透光率和温润度不能够呈现玉质鱼肚白效果。
专利202011298385.6提供了一种析晶熔块、玉质透光砖和玉质透光砖的制备方法，但是其白度及机械强度并不够，坯胎白度、透光率和温润度等质感还可以进一步地提升。

表2-对比例A1-A5及实施例A的性能测试
Figure PCTCN2021126765-appb-000001
说明：
1、由对比例A1与实施例A对比可知，对比例A1的坯体粉料并没有添加超白高岭土，导致对比例A1的陶瓷板的机械强度下降，干燥强度仅为2.82MPa，断裂模数仅为39；同时，相 对于实施例A，对比例A1的白度只有63.4°，对比例A1的坯体最大波浪变形大了0.25mm,严重影响成品平整度。而实施例A添加了超白高岭土，可以提高陶瓷板的机械强度和促进坯体质感更温润，整体呈玉质鱼肚白效果。
2、由对比例A2与实施例A对比可知，对比例A2的坯体粉料并没有添加高塑性泥；而本方案中，高塑性泥选用特定的可塑性指数和干燥抗折强度，改善坯体在干燥窑、釉线和储坯器等环节由于颠簸震动，施釉造成坯体含水率的升高导致抗破坏强度下降，生坯破损增加的情况。因此，相对于实施例A，对比例A2的生坯干燥强度和断裂模数下降，虽然坯体质感呈温润，但最大波浪变形偏大，成品平整度差，整体通体装饰仍不足，达不到玉质鱼肚白效果。由此，说明了添加特定可塑性指数和干燥抗折强度的高塑性泥可以提高坯体的机械强度、平整度及促进玉质鱼肚白效果。
3、由对比例A3与实施例A对比可知，相对于实施例A，对比例A3并没有添加高白球土，导致了对比例A3的坯体的机械强度下降，生坯干燥强度为2.78MPa，断裂模数为42。同时，对比例A3的白度也下降，仅为64.5°，且最大波浪变形0.30mm，严重影响成品平整度；另外，对比例A3的坯体也达不到玉质鱼肚白效果；由此，说明了添加高白球土可以提高坯体的机械强度、平整度及促进玉质鱼肚白效果。
4、由对比例A4、A5及实施例A对比可知，对比例A4没有添加高白钾砂，对比例A5没有添加高白钠砂，对比例A4和对比例A5的坯体质感都低于同时使用高白钾砂和高白钠砂的实施例A，说明了使用高白钾砂和高白钠砂的其中一个都会导致坯体的透光率和坯体温润质感下降。
综上所述，本方案将超白高岭土高塑性泥、高白球土、高白膨润土、熔块、高白钾砂、高白钠砂、硅灰石和坯体增强剂配合使用时，可以提高坯体的机械强度及促进玉质鱼肚白效果。

将不同对比例及实施例的坯料原料经配料，球磨，除铁，喷雾干燥，陈腐工艺制得坯体粉料。其中喷粉粉料工艺参数控制为：水份10％，容重0.95；颗粒级配范围为20目：2％；40目：45％；60目：36％；100目：15％，100目以下：2％。本实例采用干混方式制备加色线条料，浅灰线条料制备是用坯体粉料100份(干重)，加入占总质量0.1％银灰色料，混合搅拌，喷雾干燥，制得浅灰线条粉料；对于深灰色坯料，用坯体粉料100份(干重)，加入占总质量0.1％坯黑色料、0.05％银灰色料和0.03％深咖色料，搅拌均匀，喷雾干燥制得深灰色粉料；
用坯体粉料、深灰色线条料和浅灰色线条料共三种粉料按预设图案经数码布料机布设粉料，压制成型后经过坯体干燥，淋面釉，喷墨打印跟坯料预设图案对位图，淋抛釉，烧成，正反面抛光，打蜡得成品。
将对比例B1-B5及实施例B进行性能测试，如表4。
表4-对比例B1-B7及实施例B的性能测试
Figure PCTCN2021126765-appb-000003
说明：
1、由对比例B1-B3与实施例B对比可知，对比例B1的超白高岭土含铁量为0.4％，对比例B2的高塑性泥含铁量为0.4％，对比例B3的高白球土含铁量为0.4％，上述组分的铁含量都大于0.2％，导致对比例B1-B3的白度和透光率下降；由此，说明超白高岭土、高塑性泥和高白球土的含铁量不应大于0.2％。
2、由对比例B4-B5与实施例B对比可知，对比例B4的高白钾砂含铁量为0.2％，对比例B5的高白钠砂含铁量为0.2％，上述组分的铁含量都大于0.1％，导致对比例B4-B5的白度，透光率下降；由此，说明超高白钾砂和高白钠砂的含铁量不应大于0.1％。
3、由对比例B6-B7与实施例B对比可知，对比例B6的高塑性泥可塑性指数过低，只有8，导致了对比例B6的生坯干燥强度下降；而对比例B7的高塑性泥干燥抗折强度过低，仅为4MPa，导致了对比例B7的生坯干燥强度下降；说明了本方案的高塑性泥的可塑性指数不能过低，过低会导致陶瓷板的生坯干燥强度下降，以及说明了本方案的高塑性泥的干燥抗折强度不能过低，过低会导致陶瓷板生产过程的破损率增加。

Figure PCTCN2021126765-appb-000004
Figure PCTCN2021126765-appb-000005
说明：
对比例E为专利202011298385.6的实施例，其一方面没有添加高塑性泥及限定高塑性泥的可塑性指数和干燥抗折强度，也没有对超白高岭土、高塑性泥、高白球土、高白钾砂和高白钠砂的含铁量进行限定，虽然坯体质感呈温润，但坯体烧后白度及透光度相对于实施例C和实施例D较低，对比例E的坯体烧后白度为71°，透光性为3.1％，且不能呈现玉质鱼肚白效果。而实施例C和实施例D添加了高塑性泥及限定高塑性泥的可塑性指数和干燥抗折强度，限定超白高岭土、高塑性泥和高白球土的含铁量均≤0.2％；高白钾砂和高白钠砂的含铁量均≤0.1％，实施例C和实施例D能呈现玉质鱼肚白效果，白度、透光度和生坯干燥强度都比对比例E更优，实施例C和实施例D的效果示意图如图1和如图2。
需要说明的是，如图1中，A部为实施例C的陶瓷板，B部为普通石材；A部与B部对比可知，实施例C可以实现仿石材的效果；图3中，是实施例C由下至上通过光源由下至上照射时的图片，光源的透光性好；同时，可以从图3中的C部看出，隐约的花色都是从坯体中透出来(深色中外缘的浅灰色)，呈现玉质鱼肚白效果。如图2，为实施例D的产品效果示意图，呈现玉质鱼肚白效果；由此，本方案可以实现通体、透光和仿石材的效果。
