Definitions

  • the present application relates to the field of ceramics, and in particular, to a method for preparing an inkjet infiltration jade polishing tile and an inkjet infiltration jade polishing tile.
  • the jade bricks produced by the inkjet infiltration technology have the characteristics of delicate, soft, transparent and rich colors of natural stone materials. They are often used in some high-end places as high-end decorations such as background walls and decorative landscape walls. They look beautiful and high-end. Elegant, set decoration, appreciation and integration, has very considerable economic benefits.
  • the first object of the present application is to provide a method for preparing an inkjet infiltration jade polished tile, which can obtain good light transmittance, high imitation of natural stone, close texture to jade, clear pattern and texture, good viewing, and stable quality. Brick.
  • a second object of the present application is to provide the above-mentioned ink jet infiltration jade polished tile.
  • a method for preparing an inkjet infiltration jade polished tile includes the following steps:
  • Brick raw materials are added with a suitable amount of water into a slurry through ball milling, then spray-dried to obtain a powder, and then hydraulically formed to obtain a semi-finished brick, and the semi-finished brick is dried to obtain a finished brick;
  • the raw material of the brick blank is calculated by mass percentage, including: Al 2 O 3 20-25%, SiO 2 65-75%, Fe 2 O 3 0.1-0.2%, TiO 2 0.1-0.2%, CaO 0.1-0.2%, K 2 O 1-3%, Na 2 O 2-6%, MgO 0.1-0.2%, Li 2 O 0.2-0.5%, P 2 O 5 0.1-0.2%, RuO 2 0.1-0.2%, V 2 O 5 0.1 -0.2%, Bi 2 O 3 0.1-0.2%, Ce 2 O 3 0.1-0.2%, LiNbO 3 0.1-0.2%, SrZrO 3 0.1-0.2%, sodium decahydrate 0.05-0.1%, hexanitrocobalt Sodium ammonium acid 0.05-0.1%, sodium tripolyphosphate 0.05-0.1% and sodium bismuth 0.05-0.1%;
  • the powder is in mass percentage, and the particle size distribution is: 100-200 mesh 40%, 200-250 mesh 35%, 300-350 mesh 25%;
  • RuO 2 , V 2 O 5 , Bi 2 O 3 , Ce 2 O 3 , LiNbO 3 , and SrZrO 3 can form a microstructure with improved permeability under high temperature conditions, which is effective Control the degree of horizontal and vertical penetration.
  • these ingredients provide part of the color composition, and cooperate with the penetrating ink to form a texture and color closer to the natural jade, while improving the overall permeability.
  • the role of sodium decahydrate and sodium tripolyphosphate is to improve the uniformity between the various components of the brick, to ensure the overall quality of the product, to avoid local defects; at the same time, the use of sodium hexanitrocobalate cobaltate and sodium bismuth can be used Further improve the light transmission performance of the product.
  • Particle size control improves the permeability and controllability of the penetration to avoid defective products; on the other hand, it adjusts the hardness of the product to make it closer to natural jade.
  • the use of acidifying agent is to destroy the structure of the surface of the brick, and make the penetrating ink easier to penetrate.
  • the penetration aid is used to help the penetration of the ink.
  • the combination of penetration aid and acidifying agent makes the penetration in a balanced and controllable state. After the acidifying agent is finished, it is washed with deionized water to avoid the negative influence of the residual acidifying agent on the effect of the penetration aid, which will cause uneven and uncontrollable surface penetration during inkjet.
  • the control of the maximum firing temperature is compatible with the composition of the brick, especially RuO 2 , V 2 O 5 , Bi 2 O 3 , Ce 2 O 3 , LiNbO 3 , and SrZrO 3 ; at this temperature, Each component forms a proper molten and semi-melted state, which creates suitable conditions for penetrating the distribution of ink in the brick, and obtains infiltration jade polished tiles with quality close to natural jade.
  • the firing process is as follows: first heating up to 500 ° C. for 1 h, then heating up to 900 ° C. for 1 h, then heating up to 1200 ° C. for 1 h, and finally rising to the maximum firing temperature in 30-40 min. And keep for 0.5-1h; then lower to normal temperature with 2-3h.

喷墨渗花技术制造得到的玉质砖,具有天然石材质地细腻、柔润、通透、色彩丰富的特点,经常被一些高档场所用作背景墙、点缀景观墙等高档装饰,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:第一,由于砖坯成分的原因,导致成品的光透性能不够好,性能距天然玉石还很远,装饰性、观赏性不够;第二,由于现有技术中的坯体、酸化剂、助渗剂以及墨水之间的相互作用与兼容问题,使得得到产品的花色和纹理渗透不可控,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,特提出本申请。
申请内容
本申请的第一目的在于提供的一种制备喷墨渗花玉质抛光砖的方法,能够获得光透性能好,仿天然石材度高、质感贴近玉石,图案纹理清晰、观赏性好,质量稳定的砖。
