定位剥开干粒瓷砖的生产工艺及其产品Production technology and products for positioning and peeling dry grain ceramic tiles 技术领域Technical field
本发明涉及建材领域，特别涉及了定位剥开干粒瓷砖的生产工艺及其产品。The invention relates to the field of building materials, and in particular to a production process for positioning and peeling dry-grain ceramic tiles and products thereof.
背景技术Background technique
仿古瓷砖大多数是一种釉面瓷砖，一般仿古瓷砖产品会使用胶水和干粒来配合实现图案的设计，Most antique tiles are glazed tiles. Generally, antique tile products use glue and dry granules to achieve the pattern design.
目前，对干粒的定位通常采用：At present, dry granules are usually positioned as follows:
(1)胶水定位工艺，需要在瓷砖表面喷洒大量胶水，通过胶水的布施位置确定干粒的粘接位置，然后通过吹、吸的方式去除未布置胶水位置的干粒，来实现干粒的位置布施；通常仿古砖板面需要大量布施干粒，因此需要大面积布施胶水，成本较高；通过布施胶水形成的图案，由于胶水布施的精细度问题，导致干粒产品精细度不好；修改图案时，需要修改全部胶水位置，修改范围大；受胶水的稳定性影响，如温度、湿度均会导致胶水性能，导致粘接的干粒数量不稳定，从而影响产品的稳定性。(1) The glue positioning process requires spraying a large amount of glue on the surface of the ceramic tile, determining the bonding position of the dry particles through the location of the glue, and then removing the dry particles where the glue is not arranged by blowing and sucking to achieve the position of the dry particles. Distribution; Usually antique brick panels require a large amount of dry particles, so glue needs to be applied over a large area, which is costly; the pattern formed by applying glue will have poor fineness in the dry particle product due to the fineness of the glue application; modify the pattern At this time, all glue positions need to be modified, and the scope of modification is large; it is affected by the stability of the glue, such as temperature and humidity, which will affect the performance of the glue, causing the number of bonded dry particles to be unstable, thus affecting the stability of the product.
(2)在陶瓷砖表面利用剥开墨水或精雕墨水，传统的干粒粒径一般在100-300微米，使用时将干粒和悬浮剂混合后，布施在瓷砖表面，经过高温烧成，干粒颗粒固定在瓷砖表面，部分凸出在表面易产生凹凸质感，由于干粒与悬浮剂的自身性能造成釉面凹凸不平或者瓷砖纹理不清晰，导致产品的美观性和稳定性较差。(2) Use peeling ink or engraving ink on the surface of ceramic tiles. The traditional dry particle size is generally 100-300 microns. When using, mix the dry particles and suspending agent, apply them on the surface of the ceramic tiles, and burn them at high temperature. Dry granules are fixed on the surface of ceramic tiles, and part of them protrudes on the surface, which is prone to uneven texture. Due to the properties of dry granules and suspending agent, the glaze surface is uneven or the ceramic tile texture is unclear, resulting in poor aesthetics and stability of the product.
本申请所要解决的技术问题为：如何降低干粒瓷砖的成本、提高干粒瓷砖的美观性和稳定性。The technical problem to be solved by this application is: how to reduce the cost of dry-grain ceramic tiles and improve the aesthetics and stability of dry-grain ceramic tiles.
发明内容 Contents of the invention
为了克服现有技术的不足，本发明的目的在于提供定位剥开干粒瓷砖的生产工艺及其产品。In order to overcome the shortcomings of the prior art, the object of the present invention is to provide a production process for positioning and peeling dry-grain ceramic tiles and products thereof.
技术原理：通过设置油性或水性剥开墨水，配合干粒釉的油性或水性，使得干粒釉在铺淋时，干粒釉与剥开墨水之间实现自动分离，达到干粒布施效果；面釉的保水性较好，使剥开墨水不易渗透到面釉，节省了剥开墨水的用量，较少量的剥开墨水即可实现剥开效果；通过干粒粒径级配，配合悬浮剂实现理想布施效果；采用湿法干粒工艺，使面釉配合干粒釉实现干粒的烧制固定。Technical principle: By setting the oil-based or water-based peeling ink, and matching the oily or water-based dry grain glaze, the dry grain glaze and the peeling ink are automatically separated when the dry grain glaze is spread, and the dry grain spreading effect is achieved; The glaze has good water retention, which makes it difficult for the peeling ink to penetrate into the top glaze, saving the amount of peeling ink. A smaller amount of peeling ink can achieve the peeling effect; through dry particle size gradation, combined with suspending agent To achieve the ideal spreading effect; the wet dry granulation process is used to match the top glaze with the dry granule glaze to achieve the firing and fixation of the dry granules.
本发明所采用的技术方案为：The technical solutions adopted by the present invention are:
定位剥开干粒瓷砖的生产工艺，包括如下步骤：The production process of positioning and peeling dry grain ceramic tiles includes the following steps:
S1、在干燥陶瓷坯体表面布施面釉并烘干；S1. Apply top glaze on the surface of the dry ceramic body and dry it;
S2、按预设图案在面釉上打印能剥开干粒的剥开墨水；S2. Print the peeling ink on the surface glaze according to the preset pattern that can peel off the dry particles;
S3、布施干粒釉，干粒釉自动避开剥开墨水打印区域；S3. Apply the dry glaze, and the dry glaze will automatically avoid peeling off the ink printing area;
S4、烧成；S4, firing;
其中，所述剥开墨水选用精雕墨水或亚雕墨水；Wherein, the peeling ink is fine carving ink or sub-carving ink;
所述干粒釉包括干粒以及悬浮剂，所述干粒的粒径选用范围为30μm-100μm；The dry particle glaze includes dry particles and a suspending agent, and the particle size of the dry particles ranges from 30 μm to 100 μm;
所述干粒釉中的干粒包括23wt％-27wt％粒径为30μm-45μm的干粒、46wt％-50wt％粒径为45μm-75μm的干粒以及24wt％-28wt％粒径为75μm-100μm的干粒；The dry particles in the dry particle glaze include 23wt%-27wt% dry particles with a particle size of 30μm-45μm, 46wt%-50wt% dry particles with a particle size of 45μm-75μm, and 24wt%-28wt% with a particle size of 75μm-75wt%. 100μm dry particles;
所述悬浮剂由包括以下重量份的原料制成：The suspension agent is made of raw materials including the following parts by weight:
羧甲基纤维素钠10-15份；Sodium carboxymethylcellulose 10-15 parts;
甲基乙二醇5-8份；5-8 parts of methylglycol;
偏磷酸钠3-5份； 3-5 parts of sodium metaphosphate;
去离子水77—83份。77-83 parts of deionized water.
定位剥开干粒瓷砖的生产工艺及其产品通过剥开墨水配合湿法干粒生产技术，无需使用胶水，少量的墨水便可实现干粒的精准定位，降低了生产成本，提高了瓷砖表面纹理的立体效果以及精细度，并且能够在面釉上打印任意图案，使瓷砖表面的纹理更加细腻逼真，并且受环境影响较小，即使较小的细纹、小角度转角图案均可精准实现剥开。The production process of positioning and peeling dry grain ceramic tiles and its products uses peeling ink combined with wet dry grain production technology. Without the use of glue, a small amount of ink can achieve precise positioning of dry grains, reducing production costs and improving the surface texture of ceramic tiles. It has a three-dimensional effect and fineness, and can print any pattern on the surface glaze, making the texture on the ceramic tile surface more delicate and lifelike, and less affected by the environment. Even small fine lines and small angle corner patterns can be peeled off accurately. .
当需要修改图案时，也只需修改剥开墨水的打印位置，改动较小，无需使用模具，进一步降低模具对的误差对瓷砖表面的纹理造成影响，不采用胶水定位，不受胶水稳定性影响，剥开墨水剥开效果不受温度、湿度影响，大大提高了产品的生产稳定性。When you need to modify the pattern, you only need to modify the printing position of the peeled ink. The change is small and there is no need to use a mold. This further reduces the impact of mold pair errors on the texture of the ceramic tile surface. Glue positioning is not used and it is not affected by the stability of the glue. , the peeling ink peeling effect is not affected by temperature and humidity, which greatly improves the production stability of the product.
通过精雕墨水的油性与干粒釉的水性的油水排斥原理，当精雕墨水或亚雕墨水涂布在面釉表面形成图案后，在面釉表面布施干粒釉，精雕墨水或亚雕墨水中的油性成分与干粒釉产生水油分离的现象，在布施精雕墨水或亚雕墨水的地方实现定位剥开效果，并且使用少量的精雕墨水或亚雕墨水便可实现剥开效果，减少了剥开墨水的用量，降低了生产成本。Through the oil-water repulsion principle of the fine carving ink and the water-based dry grain glaze, when the fine carving ink or sub-carving ink is coated on the surface of the top glaze to form a pattern, the dry grain glaze, fine carving ink or sub-carving ink is applied on the surface of the top glaze. The oily component in the ink and the dry grain glaze produce the phenomenon of water-oil separation. The positioning and peeling effect can be achieved where the fine carving ink or sub-carving ink is applied, and the peeling effect can be achieved by using a small amount of fine carving ink or sub-carving ink. , reducing the amount of peeling ink and reducing production costs.
当干粒粒径过大时，干粒的悬浮性变差，干粒容易在墨水表面停留，不能跟随悬浮剂剥离，干粒纹理与预设打印图案不同，干粒粒径过小时，瓷砖表面纹理的凹凸效果太差，缺乏线条感或纹理感，影响产品的美观性。When the particle size of the dry particles is too large, the suspension of the dry particles becomes poor. The dry particles tend to stay on the surface of the ink and cannot be peeled off with the suspending agent. The texture of the dry particles is different from the preset printing pattern. When the particle size of the dry particles is too small, the surface of the tiles The concave and convex effect of the texture is too poor and lacks a sense of lines or texture, which affects the aesthetics of the product.
通过不同粒径的级配使干粒形成不连续颗粒体系，减小了颗粒间的摩擦，提高了粒度和密度的分布范围，有效降低了质量和体积分数占比，提高干粒的分散性，消除粘滞效应，进一步降低了干粒釉的粘性，提高了干粒釉的流动性，减少瓷砖表面纹理出现空鼓或气泡的现象。Through the gradation of different particle sizes, the dry particles form a discontinuous particle system, which reduces the friction between particles, increases the distribution range of particle size and density, effectively reduces the proportion of mass and volume fraction, and improves the dispersion of dry particles. Eliminate the viscous effect, further reduce the viscosity of the dry glaze, improve the fluidity of the dry glaze, and reduce the phenomenon of hollowing or bubbles in the surface texture of the ceramic tile.
羧甲基纤维素钠分散在去离子水中形成透明的胶体溶液，不仅能够增加悬浮剂的粘度，减少对干粒颜色表征的影响；甲基乙二醇能够提高悬浮剂的 流平性，无色透明，不会影响到干粒颜色，偏磷酸钠提高干粒的分散性，减少干粒出现团聚的现象，进一步提高干粒釉的平整性以及产品表面干粒釉图案的均匀性。Sodium carboxymethyl cellulose is dispersed in deionized water to form a transparent colloidal solution, which can not only increase the viscosity of the suspending agent and reduce the impact on the color characterization of dry particles; methyl ethylene glycol can improve the viscosity of the suspending agent. Leveling, colorless and transparent, will not affect the color of the dry granules. Sodium metaphosphate improves the dispersion of the dry granules, reduces the agglomeration of the dry granules, further improves the flatness of the dry granule glaze and the dry granule glaze pattern on the surface of the product. Uniformity.
优选的，所述面釉由包括以下重量份的原料制成：
水洗高岭土25-30份；
钾长石15-20份；
钠长石12-20份；
高白铝6-8份；
硅酸锆8-12份；
石英5-8份；
氧化锌3-5份；
碳酸钡2-5份。Preferably, the top glaze is made of raw materials including the following parts by weight:
25-30 parts of washed kaolin;
Potassium feldspar 15-20 parts;
12-20 parts of albite;
6-8 parts of high white aluminum;
8-12 parts of zirconium silicate;
5-8 parts of quartz;
3-5 parts of zinc oxide;
2-5 parts of barium carbonate.
水洗高岭土能够提高面釉的保水性，提高剥开墨水上的停留时间，减少剥开墨水渗入到面釉的现象发生，水洗高岭土含量过少时，面釉过于疏松，剥开墨水容易深入到面釉层中，干粒釉的剥开效果较差，产品表面的图案与预设图案容易产生较大偏差，水洗高岭土过多时，面釉的流动性变差，不利于面釉的流平，影响瓷砖的平整度，并且对面釉的白度以及光泽度有较大影响，增加了产品的色差，从而影响产品质量。Washed kaolin can improve the water retention of the top glaze, increase the residence time of the peeling ink, and reduce the penetration of the peeling ink into the top glaze. When the content of washed kaolin is too low, the top glaze will be too loose, and the peeling ink will easily penetrate into the top glaze. In the middle layer, the peeling effect of the dry glaze is poor, and the pattern on the product surface is prone to large deviations from the preset pattern. When too much washed kaolin is used, the fluidity of the top glaze becomes poor, which is not conducive to the leveling of the top glaze and affects the ceramic tiles. The flatness of the glaze has a great impact on the whiteness and gloss of the glaze, which increases the color difference of the product and thus affects the quality of the product.
优选的，所述干粒与悬浮剂的质量比为1:(2.5-4)。Preferably, the mass ratio of the dry particles to the suspending agent is 1:(2.5-4).
当悬浮剂过少时，干粒釉粘度过大，导致干粒釉无法均匀地分布在面釉的表面，悬浮剂过多时，干粒的含量较少，降低了产品的表面的线条感，降低了美观性。When there is too little suspending agent, the viscosity of the dry glaze is too high, causing the dry glaze to be unable to be evenly distributed on the surface of the top glaze. When there is too much suspending agent, the content of dry particles is less, which reduces the line feel on the surface of the product and reduces the Aesthetics.
一种定位剥开干粒瓷砖，包括自下向上依次设置的坯体层、面釉层、墨水层和干粒层，所述面釉层由面釉制成，所述墨水层由涂布量为50g/m2-70g/m2的剥开墨水制成，所述干粒层由干粒釉制成。 A positioning and peeling dry grain ceramic tile, including a base layer, a top glaze layer, an ink layer and a dry grain layer arranged sequentially from bottom to top. The top glaze layer is made of top glaze, and the ink layer is determined by the coating amount. It is made of peeling ink of 50g/ m2-70g / m2 , and the dry grain layer is made of dry grain glaze.
墨水层的涂布量过少墨水的油性较低，干粒釉的剥开效果较差，墨水层的涂布量过大时，增加了成本，并且增加了喷墨机的工作强度，降低了产品的生产效率。If the amount of ink layer applied is too small, the oiliness of the ink is low, and the peeling effect of the dry glaze is poor. When the amount of ink layer applied is too large, it increases the cost, increases the working intensity of the inkjet machine, and reduces the cost of the inkjet machine. Product production efficiency.
本发明的有益效果在于：The beneficial effects of the present invention are:
该定位剥开干粒瓷砖的生产工艺及其产品通过剥开墨水配合湿法干粒生产技术，在大面积布干粒的砖面，只需少量剥开墨水即可实现整体干粒布施，成本低；通过干粒的级配，提高瓷砖表面纹理的凹凸效果、线条感以及纹理感，提高产品的美观性；修改图案时，也只需修改剥开墨水的打印位置，改动较小；通过悬浮剂与干粒之间的配合，提高干粒的分散性，减少干粒出现团聚的现象，提高瓷砖的美观性。The production process and products of positioning and peeling dry-grain ceramic tiles use peeling ink combined with wet dry-grain production technology to spread dry grains over a large area of tiles. Only a small amount of peeling ink can be used to achieve overall dry-grain distribution at a low cost. Low; through the gradation of dry particles, the concave and convex effect, line sense and texture of the ceramic tile surface texture are improved, and the aesthetics of the product is improved; when modifying the pattern, only the printing position of the peeled ink needs to be modified, and the change is small; through suspension The cooperation between the agent and the dry particles improves the dispersion of the dry particles, reduces the agglomeration of the dry particles, and improves the aesthetics of the ceramic tiles.

本发明实施例1与对比例1-9制成的瓷砖，性能结果见表2。The performance results of the ceramic tiles made in Example 1 and Comparative Examples 1-9 of the present invention are shown in Table 2.
表2性能结果

Table 2 Performance results

通过实施例1和对比例1-9的性能对比可以看出，本发明通过坯体层、面釉层、墨水层以及干粒层制成的定位剥开干粒瓷砖，替换胶水定位干粒工艺，最终制成低成本、高精细度、稳定性高的干粒瓷砖。It can be seen from the performance comparison between Example 1 and Comparative Examples 1-9 that the present invention uses a positioning and peeling dry-grain ceramic tile made of a green body layer, a glaze layer, an ink layer and a dry-grain layer to replace the glue positioning dry-grain process. , and finally made into dry granular ceramic tiles with low cost, high precision and high stability.
具体的，对比例1面釉中的水洗高岭土为20g，剥开墨水在面釉上的停留时间受到影响，剥开墨水容易渗入到面釉层内，导致墨水层表面不均匀，干粒釉容易附着在墨水层表面，使干粒纹理与预设打印图案之间出现偏差，影响瓷砖的质量；对比例2面釉中的水洗高岭土为40g，减少了剥开墨水渗入面釉的现象发生，但是面釉流动性变差，造成面釉层分布不均匀，进而导致干粒层与墨水层厚度不均，影响瓷砖的质量以及手感，制成的瓷砖也会出现色差。而实施例1中的水洗高岭土为28g，即减少了墨水渗入面釉表面的现象发生，也降低了面釉对瓷砖颜色的影响，提高了干粒瓷砖的稳定性。Specifically, the amount of washed kaolin in the top glaze of Comparative Example 1 is 20g. The residence time of the peeling ink on the top glaze is affected. The peeling ink easily penetrates into the top glaze layer, resulting in uneven surface of the ink layer, and the dry glaze is easy to Adhere to the surface of the ink layer, causing deviations between the dry grain texture and the preset printing pattern, affecting the quality of the ceramic tiles; the water-washed kaolin in the surface glaze of Comparative Example 2 is 40g, which reduces the phenomenon of peeling ink and penetrating into the surface glaze, but The fluidity of the top glaze becomes poor, resulting in uneven distribution of the top glaze layer, which in turn leads to uneven thicknesses of the dry particle layer and the ink layer, affecting the quality and feel of the ceramic tiles, and the finished ceramic tiles will also have color differences. The amount of washed kaolin in Example 1 is 28g, which reduces the phenomenon of ink penetrating into the surface of the top glaze, reduces the impact of the top glaze on the color of the ceramic tiles, and improves the stability of the dry ceramic tiles.
根据表2中实施例1与对比例3-4的性能对比可知，对比例3的精雕墨水较少，干粒釉的剥开效果较差，干粒容易在墨水层表面附着，干粒纹理与预设打印图案之间出现偏差，影响了干粒瓷砖表面纹理的精细度；对比例4的精雕墨水过多，提高了喷墨机的工作强度，并且会产生浪费，提高了生产成本；而实施例1中精雕墨水的用量为60g/m2，在保证干粒釉的剥开效果的而同时，也减少了浪费，提高了瓷砖的质量，降低了生产成本。 According to the performance comparison between Example 1 and Comparative Examples 3-4 in Table 2, it can be seen that Comparative Example 3 has less finely carved ink, the peeling effect of the dry grain glaze is poor, the dry grains are easy to adhere to the surface of the ink layer, and the dry grain texture There is a deviation from the preset printing pattern, which affects the fineness of the surface texture of the dry granular ceramic tiles; there is too much fine carving ink in Comparative Example 4, which increases the working intensity of the inkjet machine, generates waste, and increases production costs; In Example 1, the amount of fine carving ink is 60g/m 2 , which not only ensures the peeling effect of the dry glaze, but also reduces waste, improves the quality of the ceramic tiles, and reduces the production cost.
根据表2中实施例1与对比例5-6的性能对比可知，对比例5中的干粒与悬浮剂的质量比为(1:2)，此时，干粒釉粘度过大，导致干粒釉无法均匀地分布在面釉的表面，干粒层的表面不平整，触感较差，干粒纹理不清晰，瓷砖表面纹理的精细度较差；对比例6中的干粒与悬浮剂的质量比为(1:5.1)，干粒的含量较少，降低了产品的表面的线条感，降低了美观性，触感无明显颗粒感。而实施例1的瓷砖表面平整，纹理清晰，同时具备颗粒触感。According to the performance comparison between Example 1 and Comparative Examples 5-6 in Table 2, it can be seen that the mass ratio of dry particles to suspending agent in Comparative Example 5 is (1:2). At this time, the viscosity of the dry particle glaze is too large, resulting in dry The granular glaze cannot be evenly distributed on the surface of the top glaze. The surface of the dry granule layer is uneven and has poor touch. The texture of the dry granules is unclear and the fineness of the surface texture of the ceramic tiles is poor. The difference between the dry granules and the suspending agent in Comparative Example 6 The mass ratio is (1:5.1), and the content of dry particles is small, which reduces the line feeling of the surface of the product, reduces the aesthetics, and has no obvious graininess to the touch. The ceramic tiles in Example 1 have a smooth surface, clear texture, and a grainy feel.
根据表2中实施例1与对比例7-9的性能对比可知，对比例7-9中，干粒的颗粒均未进行级配，对比例7，干粒的粒径过小，导致瓷砖表面干粒层的颗粒触感不明显，并且干粒层缺乏线条感，影响了干粒瓷砖的质量；对比例8干粒的分散性变差，干粒在悬浮剂中分散不均，导致干粒层不平整；对比例9干粒粒径过大，干粒层的手感太过粗糙。干粒分散不均匀并且容易附着在墨水层，干粒纹理与预设打印图案之间出现偏差，影响干粒瓷砖的质量。According to the performance comparison between Example 1 and Comparative Examples 7-9 in Table 2, it can be seen that in Comparative Examples 7-9, the particles of the dry particles are not graded. In Comparative Example 7, the particle size of the dry particles is too small, causing the surface of the ceramic tiles to be damaged. The particles in the dry particle layer have no obvious touch, and the dry particle layer lacks a sense of lines, which affects the quality of the dry particle ceramic tiles; the dispersibility of the dry particles in Comparative Example 8 becomes worse, and the dry particles are unevenly dispersed in the suspension agent, resulting in a dry particle layer Uneven; the dry particle size of Comparative Example 9 is too large, and the dry particle layer feels too rough. The dry particles are unevenly dispersed and easily adhere to the ink layer. There is a deviation between the dry particle texture and the preset printing pattern, which affects the quality of the dry particle ceramic tiles.
