Detailed Description
The invention provides a production process of a ceramic tile with metal luster, the ceramic tile and metal dry particle glaze, and in order to make the purpose, technical scheme and effect of the invention clearer and clearer, the invention is further described in detail by referring to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, the present invention provides a production process of a ceramic tile with metallic luster, which is characterized by comprising the following steps:
(1) preparing metal dry particles: adding the uniformly mixed frit raw materials into a tank furnace to be melted into glass liquid, making the glass liquid flow into a water tank in a columnar mode, and crushing the glass liquid into particles by water flow; drying, crushing and screening to prepare metal dry particles; the glass liquid is subjected to microcrystallization treatment to refine crystal grains, which is beneficial to existence of grain boundaries among the crystal grains and improvement of atomic diffusion, and then water quenching is performed to fix the crystal grain structure, so that the growth of the crystal grains is avoided, the refinement of the crystal grains is realized, and the problems of low smoothness of the brick surface and insufficient metal gloss caused by coarse crystal grains are avoided; the rigidity of the metal dry particles is improved, and the hardness of the metal dry particle glaze is further improved.
(2) Preparing a metal dry particle glaze material: uniformly mixing the metal dry particles and a suspending agent according to the weight ratio of 1 to (2-3); the suspending agent is one of methyl glycol, sodium carboxymethyl cellulose and polymethylsiloxane; the suspending agent is an organic matter suspending agent, can be used for improving the suspending capacity of each component in the metal dry particle glaze, and reducing the sedimentation speed of each component, so that the metal dry particle glaze has good fluidity and is easy to level, and the phenomena that the local metal luster on the surface of a brick is stronger and the local metal luster is weaker and the metal luster on the surface of the brick is non-uniform due to the sedimentation and agglomeration of the components are avoided. The metal dry particles and the suspending agent in the proportion enable the metal luster of the brick surface to be fine and smooth and to be uniformly distributed.
(3) Adding water into raw materials of the green brick, ball-milling the raw materials to prepare powder, and then pressing and forming the powder; after primary drying and water spraying, distributing metal dry particle glaze on the green brick; printing patterns/grains on the brick surface by adopting one of silk screen printing, ink jet printing and roller printing;
(4) spreading protective glaze: distributing protective glaze on the printed brick surface;
(5) and (5) drying for the second time, firing and polishing to obtain the ceramic tile with metallic luster.
Compared with the prior art that the overglaze is distributed firstly and then the metal dry particle glaze is distributed, the refractory metal dry particle glaze is distributed under the protective glaze by directly distributing the metal dry particle glaze on the brick blank and then distributing the protective glaze, the protective glaze fully fills the unevenness of the metal dry particle glaze layer, and the brick surface has high fineness and luster which is closer to the metal luster texture due to the refraction of the metal dry particle to light rays after polishing, and the brick surface has high flatness and high smoothness when touching the brick surface.
In addition, the production process of the ceramic tile with the metal luster adopts a one-time firing method, so that the production process is simplified, and the green brick has high vitrification degree, hardness and strength; the glaze and the green brick are mature simultaneously, which is beneficial to the formation and growth of an intermediate crystal layer and further increases the strength and transparency of the ceramic tile; heat loss is less; the production cost can be reduced without increasing or improving the production line.
Specifically, the green brick comprises the following components in parts by weight: 65-67 parts of SiO219 to 21 parts of Al2O31.9-2.5 parts of Na2O, 2.3-3.3 parts of K2O, 0.6-1.2 parts of MgO, CaO less than or equal to 1 part, and Fe2O3、TiO2The total parts are less than or equal to 1 part. The green brick has the most appropriate components and proportion, high strength and no cracking; the expansion coefficient of the brick powder is 210-220, so that the brick powder cannot have large volume change in the drying and firing processes, the probability of shrinkage of green bricks is reduced, and waste products are reduced.
Further, the metal dry particles comprise the following components in parts by weight: 31 to 33 parts of SiO29 to 11 parts of Al2O31-2 parts of CaO, 0-0.5 part of MgO, and 1.2-1.6 parts of K2O, 1.4-2 parts of Na2O, 2.5-3 parts of B2O38 to 8.5 parts of Cr2O33.8 to 4.2 parts of NiO and 25 to 27 parts of NiO
Fe2O34-5 parts of SnO2；Fe2O3Is red or deep red amorphous powder with high covering power, NiO is green black cubic crystal, and Cr is2O3The crystal is light to dark green fine hexagonal crystal, has high covering power and very stable chemical property, and is refractory to metal; the above substances enable firing of a grey-black glaze layer with metallic luster. B is2O3Can be combined with several metal oxides to form boron glass with characteristic color, and B is added2O3The miscibility with other components provides a metallic luster with richer colors. SnO2For visible light hasThe metal dry particle glaze layer has the characteristics of good permeability, stable chemical property, specific infrared radiation reflection and the like, and has the advantages of improving the permeability of the metal dry particle glaze layer, facilitating the light to enter the metal dry particle glaze layer and enabling the refractive index of the metal luster to be higher.
Further, the specific gravity of the metal dry particle glaze is 1.20-1.30g/cm3(ii) a The flow rate is 30-35 s; the specific gravity of the metal dry particle glaze material has important influence on the glazing time and the thickness of the glaze layer. The glaze material has high specific gravity, a thicker glaze layer can be obtained in a short time, but the glaze material has high specific gravity, namely the content of metal dry particles is high, and when the glaze material is applied, the metal luster is too strong, the optimal visual effect cannot be achieved, the glaze layer is easy to cause uneven thickness and poor permeability, and the light entering is further influenced; the glaze material has small specific gravity, and the glaze layer with certain thickness needs to be glazed for a plurality of times or glazed for a long time, thereby improving the production cost. The flow rate of the glaze is related to the viscosity, fluidity, etc. of the glaze; the flow rate is slow, namely the viscosity is high, the fluidity is poor, the effect of the glaze after leveling is poor, and even the flatness of the brick surface is influenced; the flow rate is high, the effect of metal dry particles attached to the surface of the tile and the glazing time are influenced, a glaze layer and a green tile body are easily layered, and the overall strength of the ceramic tile is influenced. The ranges of the specific gravity and the flow rate are most suitable, and the glaze is favorably applied.
Specifically, the metal dry particle glaze is distributed and applied by adopting a bell jar glaze spraying mode, and the glaze spraying amount is 260-300g/m2(corresponding to a tile with a specification of 600X 600mm, the amount of application is 95-100 g); the bell jar glaze pouring operation is simple, the leveling effect of the glaze is good, and the metal dry particles are uniformly distributed on the surface of the tile to obtain the ceramic tile with uniform metal luster; the glaze pouring amount determines the thickness of the glaze layer, the metal luster formed by the thickness of the glaze layer within the range has the best effect, and the metal luster is not too thick, so that the texture of the metal luster is distorted and deviates from the actual metal luster; the thickness is not too thin, and the strength of the metallic luster is not enough.
Further, the protective glaze comprises the following components in parts by weight: 44-47 parts of SiO215 to 17 parts of Al2O34-6 parts of CaO, 1-2 parts of MgO and 2-4 parts of K2O, 2.5-4 parts of Na2O, 5-7 parts of BaO, 11 &14 parts of ZnO and 0-1 part of TiO20 to 2 parts of ZrO20 to 1 part of B2O3. The protective glaze has good permeability, and the main component is basically the same as the metallic luster glaze layer, so that a thicker crystal layer is formed between the main component and the metallic luster glaze layer, the bonding strength is improved, and the occurrence of layering is avoided.
Specifically, the specific gravity of the protective glaze is 1.35-1.40g/cm3(ii) a The flow rate is 30-35 s; the protective glaze adopts bell jar pouring glaze, and the pouring glaze amount is 110-160g/m2(corresponding to a tile with a specification of 600X 600mm, the amount of the coating is 40-60 g). The performance is most suitable, which is beneficial to forming the protective glaze layer with the best thickness, viscosity and fluidity, and further beneficial to forming the protective glaze layer with good permeability and high glossiness, which is beneficial to light entering and reflecting and does not influence the color development of the metallic luster glaze layer.
Furthermore, the firing temperature is 1180-1210 ℃, and the firing period is 60-70 min. The ceramic tile is easy to deform due to the excessively high firing temperature, the viscosity of glaze materials is increased, the exhaust is not facilitated, the phenomena of foaming, pinholes or glaze flowing are easy to occur on the glaze surface, and the quality, transparency, acid and alkali resistance, corrosion resistance, pollution resistance and the like of the glaze layer are influenced; the firing temperature is too low, the ceramic effect of the ceramic tile is incomplete, and the strength of the product is easily reduced; the above firing temperature ratio Fe2O3、Cr2O3、NiO、SnO2The melting point of (2) is low, so that the metal with metallic luster is not burnt and melted, and the strong luster feeling of the metal is kept, so that the luster is closer to the texture of metallic luster.
