80度白度、色比羊脂的瓷质抛光砖及其制备方法
技术领域:
本发明涉及瓷质渗花抛光砖的制备技术领域,尤其涉及一种80度白度、色比羊脂的瓷质抛光砖及其制备方法。
背景技术:
翡翠玉石、玛瑙石等名贵石材是宝石类的一种原矿石,它具有质地细腻、柔润、通透、色彩丰富等特点,经过精心雕琢后,贵气十足。由于它们通透性好,肌理细腻、柔润,这些原矿石材经过打磨抛光后被一些高档场所用作背景墙、点缀景观墙等高档装饰,由于这些高档宝石级的石材具有特殊的通透性,在其背面灯光的照射下,其内部石材肌理可以从正面透露出来,更显得富丽堂皇、高档典雅,贵气十足,集装饰性、欣赏性与一体,受到众多新贵人士的追捧,价格居高不下,而普通陶瓷墙地砖随着装饰技术的不断革新,其表面图案、颜色、纹理的效果均可达到翡翠玉石、玛瑙石等名贵石材的表面效果,但这些石材的内部肌理及通透性目前普通陶瓷墙地砖还无法达到,如果能把这些名贵石材的内部肌理及通透性复制在陶瓷墙地砖产品上,使这种日渐稀少、可遇不可求的名贵宝石级石材,通过普通墙地砖的铺贴,再加上灯光的点缀,从内到外超级纯洁,更好地还原顶级白色系天然石材之美。从而使居家富丽堂皇、高档风雅,更显贵气,必然会在陶瓷装饰技术中产生明显的技术革新,引领陶瓷装饰技术的新发展,具有非常可观的经济效益。
发明内容:
本发明的目的在于克服上述缺点,提供一种80度白度、色比羊脂的瓷质抛光砖及其制备方法,在不对现有瓷质渗花抛光砖生产工艺作出重大改变的基础上,通过对坯体的配方组成、釉浆的配方组成、坯体表面酸化剂的配方组成、助渗剂的配方组成、喷坯体表面酸化剂的喷剂量、喷助渗剂的喷剂量、窑炉烧成工艺的调整与优化,通过精选高白纯净的原材料以及新材料的创新下推出的一款超白的玉瓷砖。碾压了之前世界热捧的75度白的瓷抛砖。增白主要是靠硅酸锆和氧化铝,80度超白玉瓷砖大大高于普通50度的白砖,并且通体洁白、色比羊脂的白色美感,从内到外超级纯洁,更好地还原顶级白色系天然石材之美。同时渗透到产品内部图案的颜色、纹理与表面基本一致,清晰可见、立体感强,具有翡翠玉石、玛瑙石等名贵通透宝石级石材般的独特装饰效果,且产品表面质量好,耐污强、硬度高、耐磨性强、无针孔、熔洞等缺陷,经微观结构分析,产品表面析满了如天然翡翠玉石中的钠铝硅酸盐矿物般的硅酸铝钠(AlNaO6Si2)细小晶体。同时该技术具备较强的普适性,易于在行业内推广。

按所述的釉浆的组分的重量百分比含量,选取相应比例的钾长石和钠长石及石英的混合砂、叶蜡石原料、霞石正长岩原料、锂瓷石原料、粘土原料以及外加重量百分比为0.6%~0.8%的辅助原料,再加入适量的水经球磨细碎成细度为250目筛的筛余为质量百分比0.1%~0.2%且含质量百分比为31%~33%水分的浆料,经除铁过筛制成比重为1.77~1.80g/cm3的浆料。
本发明的80度白度、色比羊脂的瓷质抛光砖及其制备方法:
通过对坯体、釉浆配方组成的优化,在坯体、釉浆配方中引入了含P2O5成分的锂瓷石原料(如江西大丰瓷石公司的锂瓷石),一方面锂瓷石中的LiO2和P2O5是强熔剂,熔点低,在高温中可以加快游离石英的熔融,增加融体的透明度,从而保证产品的透光性能;另一方面LiO2、P2O5还有助于渗透到坯体中的喷墨渗花墨水的发色,使色彩丰富、艳丽。同时引入LiO2还可以生成细小的结晶,P2O5是晶核剂,因此LiO2、P2O5对硅酸铝钠AlNaSi2O4细小晶体的生成还起到促进作用。
在坯体、釉浆配方中引入了霞石正长岩原料,由于霞石正长岩的矿物主要是长石类和霞石(Na,K)AlSiO4的固溶体,它在1060℃左右开始熔化,在高温下能溶解石英,故其熔融后的粘度较高,因此不但保证了产品的透光性能,还保证了坯体在高温烧成时不易变形,且热稳性和机械强度都高。
在坯体、釉浆配方中通过添加硅酸锆和氧化铝大大提高表面白度。
同时坯体、釉浆配方组成的优化还保证了坯体、釉浆在高温中与助渗剂的硅溶胶中的钠米硅反应,在表面生成硅酸铝钠(AlNaO6Si2)细小晶体,而这种晶体是一种极细的无定形结构颗粒,呈球形,具有很小的粒径,颗粒是以不同粘结性的聚集体存在,如硬玉(翡翠)中的天然钠铝硅酸盐矿物;这些晶体不但可以使光线直透而不受阻挡,同时还因其呈球形,细密程度高,经抛光打蜡后温润细腻,如加工后的翡翠,柔润、细腻、洁白。
坯体表面酸化剂配方组成的优化及喷酸化剂量的优选,保证了坯体表面的气孔度及气孔的孔径,有利喷墨渗花墨水的渗透速度和深度,保证了图案的颜色及纹理的饱满度,从而不会因图案渗透不够深,在后期抛光工序造成缺花、图案纹理、层次不清等缺陷的产生。
助渗剂配方组成的优化及喷助渗剂量的优选,一方面保证了助渗剂中硅溶胶中的纳米硅能与坯体在高温中生成硅酸铝钠(AlNaO6Si2)细小晶体,因为纳米硅粒径小,分布均匀,比表面积大,高表面活性,不但保证了喷墨渗花墨水的发色,还极易与坯体中的Na2O、Al2O3、SiO2等氧化物反应,在表面生成硅酸铝钠细小晶体;同时助渗剂中的醋酸乳液还可以保证喷墨渗花墨水快速凝结成细小颗粒,沉降到受坯体表面酸化剂作用而形成的气孔里,不会向其它地方扩散,从而保证图案的整体性、清晰度及渗透的深度。
烧成工艺的优化,在1100℃~1150℃温度区域进行合适的保温,一方面保证了坯体在高温中融体的透明度,确保了产品的透光性能;另一方面,在这一区域进行保温,有利于硅酸铝钠(AlNaO6Si2)细小晶体的生成。
本发明的80度白度、色比羊脂的瓷质抛光砖及其制备方法有如下优点:
1、由于优化了坯体、釉浆的配方组成、坯体表面酸化剂的配方组成、助渗剂的配方组成、坯体表面酸化剂的喷剂量、助渗剂的喷剂量及烧成工艺的调整与优化等,从而使制造的产品碾压了之前世界热捧的75度白的瓷抛砖。80度超白玉瓷砖大大高于普通50度的白砖,并且通体洁白、色比羊脂的白色美感,从内到外超级纯洁,更好地还原顶级白色系天然石材之美。经微观结构分析,产品表面析满了硅酸铝钠(AlNaO6Si2)细小晶体。
2、该产品表面平整度、断裂模数、抗折强度、耐磨性、抗热震性、放射性均达到GB/T4100-2015附录G、GB6566-2010中A类标准要求。
3、可塑性强,应用广泛。因为洁白,所以砖面上可以表达出更多的、更好的以前难以表达的图案和色调;因为洁白,所以可以与其他色调更好地搭配,是设计师的最爱和首选。
4、该产品采用现有的喷墨渗花抛光砖的生产工艺,易于实现产业化规模。
