Description
技术领域
本发明涉及陶瓷领域,具体而言,涉及一种砖坯及喷墨渗花玉质抛光砖。
背景技术
天然石材尤其是天然玉石,具有质地细腻、柔润、通透、色彩丰富等特点,经常被一些高档场所用作背景墙、点缀景观墙等高档装饰,在灯光的照射下,其内部石材肌理显现出来更显得富丽堂皇、高档典雅,集装饰性、欣赏性与一体,具有非常可观的经济效益。
现有技术中,有使用喷墨渗花技术进行玉质砖制造的,但是存在以下缺陷:由于现有技术中的坯体与墨水之间的渗透性兼容问题,使得得到产品的花色和纹理渗透不均匀,横向渗透和纵向渗透深度不容易控制,使得整体质量难以均衡控制,导致产品难以大规模批量生产。
有鉴于此,特提出本发明。
发明内容
本发明的第一目的在于提供的一种砖坯,其成分和表面微观结构与渗花墨水配合,能够提高渗花墨水在砖体表面的颜色对比度,改善视觉效果;同时能够使得常规的渗花墨水的横向渗透和纵向渗透变得可控。
本发明的第二目的在于提供一种喷墨渗花玉质抛光砖,光透性能好、图案纹理清晰、质感贴近玉石,强度高,质量稳定。
为了实现本发明的上述目的,特采用以下技术方案:
一种砖坯,以质量百分比计,包括:
Al2O320-25%、SiO265-75%、Fe2O30.1-0.2%、TiO20.1-0.2%、CaO0.1-0.2%、K2O1-3%、Na2O2-6%、MgO0.1-0.2%、Li2O0.2-0.5%、P2O50.1-0.2%、RuO20.1-0.2%、V2O50.1-0.2%、Bi2O30.1-0.2%、Ce2O30.1-0.2%、LiNbO30.1-0.2%和SrZrO30.1-0.2%。
除了砖坯的常见成分之外,RuO2、V2O5、Bi2O3、Ce2O3、LiNbO3、SrZrO3这些成分在高温状态下,能够形成改善渗透性能的微观结构,能够有效的控制横向渗透和纵向渗透的程度,此外,这些成分提供部分颜色构成,与渗花墨水配合,形成更加贴近天然玉石的纹理和颜色,同时改善整体的通透性。
优选地,所述的砖坯还包括辅料,所述辅料,以为质量百分比计,包括十水合硫酸钠0.05-0.1%、六硝基合钴酸铵钠0.05-0.1%、三聚磷酸钠0.05-0.1%和铋酸钠0.05-0.1%。
辅料的作用是提高砖坯各成分之间的均匀性,保证产品整体的质量,避免产生局部瑕疵。同时,六硝基合钴酸铵钠和铋酸钠的使用可以进一步改善产品的光透性能。
进一步优选地,以质量百分比计,包括:Al2O322%、SiO268.6%、Fe2O30.15%、TiO20.15%、CaO0.15%、K2O3%、Na2O4%、MgO0.15%、Li2O0.5%、P2O50.15%、RuO20.15%、V2O50.15%、Bi2O30.15%、Ce2O30.1%、LiNbO30.1%、SrZrO30.1%和所述辅料;
所述辅料为十水合硫酸钠0.1%、六硝基合钴酸铵钠0.1%、三聚磷酸钠0.1%和铋酸钠0.1%。
最佳的成分配比,可以获得更优的产品性能。
更加优选地,所述砖坯由原料经粉碎制成粉料,然后压制而成;所述粉料以质量百分比计,粒度分布为:100-200目40%,200-250目35%,300-350目25%。
粒度控制,一方面是改善渗透性能,提高渗透的可控性,避免出现残次品;另一方面是为了调整产品的硬度,使其更加靠近天然玉石。
本申请提供一种喷墨渗花玉质抛光砖,包括所述的砖坯,还包括:酸化剂和助渗剂;
所述酸化剂为弱酸的水溶液,pH值为4.2-5.8;所述弱酸为醋酸、碳酸、次氯酸、氢氟酸中的一种或多种;
所述助渗剂,按重量份数计,包括硅溶胶50-80份、醋酸乙烯乳液20-40份、脂肪醇聚氧乙烯醚5-10份。
酸化剂的使用是为了破坏砖坯的表面的结构,使得渗花墨水更容易渗透,但是pH值的控制是为了控制这一破坏行为,使渗花墨水的渗透处于可控范围。助渗剂的使用,是为了帮助渗花墨水的渗透。助渗剂与酸化剂的配合,使得渗透处于一种平衡的可控的状态。
优选地,所述酸化剂的喷剂量为30-50g/m2,所述助渗剂的喷剂量为40-60g/m2。
喷剂量的控制是为了进一步对渗透行为进行控制,保证产品质量的稳定性。
更加优选地,最高烧成温度范围为1200-1220℃。
最高烧成温度的控制,是与砖坯成分相适应的。在这一温度条件下,各组分形成恰当的熔融和半熔融状态,为渗透墨水在砖坯内的分布,创造合适的条件,获得品质贴近天然玉石的渗花玉质抛光砖。
与现有技术相比,本发明的有益效果为:
1.通过选择砖坯的成分,尤其是RuO2、V2O5、Bi2O3、Ce2O3、LiNbO3、SrZrO3这些成分在高温状态下,能够形成改善渗透性能的微观结构,能够有效的控制横向渗透和纵向渗透的程度,形成更加贴近天然玉石的纹理和颜色,同时改善整体的通透性;
2.助渗剂与酸化剂的配合,使得渗透处于一种平衡的可控的状态,可以获得性能优异的产品。

2、酸化剂和助渗剂的配制
取适量醋酸和氢氟酸,调节pH值至4.6,得到弱酸水溶液;取硅溶胶70份、醋酸乙烯乳液30份、脂肪醇聚氧乙烯醚8份,混合均匀得到助渗剂;
3、表面处理
将制备好的砖坯先喷施酸化剂,控制喷剂量为40g/m2;然后喷施助渗剂,助渗剂的喷剂量为50g/m2;
4、喷墨渗花和烧制
将步骤3所得砖坯使用渗花墨水进行喷墨渗花,然后送入窑炉中烧制,控制最高烧成温度为1210℃,控制总体烧制时间2h;
5、后处理
将烧成的半成品经过磨边、抛光、打蜡,得到成品。
实施例4
与实施例3不同的是,砖坯的成分不同,具体如下:Al2O323%、SiO267%、Fe2O30.2%、TiO20.2%、CaO0.2%、K2O3%、Na2O5%、MgO0.18%、Li2O0.2%、P2O50.1%、RuO20.1%、V2O50.1%、Bi2O30.1%、Ce2O30.1%、LiNbO30.1%、SrZrO30.1%和辅料,即可;辅料为十水合硫酸钠0.08%、六硝基合钴(Ⅲ)酸铵钠0.08%、三聚磷酸钠0.08%和铋酸钠0.08%。
比较例1
与实施例1相比,不同之处在于,砖坯中不含有RuO2、V2O5、Bi2O3、Ce2O3、LiNbO3和SrZrO3;
比较例2
与实施例2相比,不同之处在于,弱酸水溶液pH值为4;
比较例3
与实施例3相比,不同之处在于,弱酸水溶液pH值为6;
比较例4
与实施例4相比,不同之处在于,助渗剂不含脂肪醇聚氧乙烯醚;
比较例5
与实施例2相比,不同之处在于,最高烧成温度为1250℃。
测试实施例1-4和比较例1-5所得的500组产品的参数得到平均值,结果如下表1所示:
表1测试结果
需要说明的是,上表1中良品率的检测标准是:表面无裂纹、表面平整度小于2mm、渗花深度和广度可控且误差不超过5%;光直线透过率是指在光照强度为1000w/m2的平行光源照射下,在光源背侧使用光照度计测得的光强占光源光强的比率。其中,翡翠的最大光直线透过率为12.67%。
由上表1可知,RuO2、V2O5、Bi2O3、Ce2O3、LiNbO3和SrZrO3的添加,能够有效的改善成品的光透性能,使其获得更加近似于玉石的效果,同时能够对渗花的横向和纵向进行控制,保证良品率;辅料的使用,可以提高光直线透过率,提高产品的韧性,与其他成分一起协调作用,提高良品率;酸化剂pH的控制及弱酸的选择,对光透性能影响有限,但是对于控制渗花的效果有较大影响,进而影响良品率;助渗剂成分的选择,尤其是脂肪醇聚氧乙烯醚的使用,是为了控制助渗剂的效果,保证渗花工艺可控,提高良品率;烧制温度的控制,是与砖坯成分相匹配的,有利于优化内部及表面结构,提高光透性能和强度。
本申请提供的砖坯及喷墨渗花玉质抛光砖,光透性能好、图案纹理清晰、质感贴近玉石,强度高。
对于本领域的技术人员来说,本申请可以有各种更改和变化。凡在本申请的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本申请的保护范围之内。尽管已用具体实施例来说明和描述了本发明,然而应意识到,在不背离本发明的精神和范围的情况下可以作出许多其它的更改和修改。因此,这意味着在所附权利要求中包括属于本发明范围内的所有这些变化和修改。
