At present, the integrated bathroom decoration wallboard for high-end positioning mainly adopts ceramic tiles and stone materials, and the middle-low end mainly adopts PET color steel plates and SMC color film coating. The former has good decoration, appearance and durability, but high cost; the latter is low in cost, but poor in performance and short in service life. Therefore, there is a need to develop a decorative board that has low cost, and has the quality, decorative diversity and durability of stone/ceramic tile.

Artificial stone is a new type of material, and currently developed artificial stones include organic artificial stones and inorganic artificial stones. Based on different material components, the preparation method of the inorganic artificial stone is also different from that of the organic artificial stone. The inorganic artificial stone plate is mostly prepared by a pouring method or a pressing plate method. For example, the traditional cement-based large panel is generally prepared by adopting a pouring method, but the substrate prepared by the pouring method has high porosity, high water absorption and large drying shrinkage, so that the panel is warped after being installed on a wall, the appearance is influenced, and potential safety hazards exist. For example, inorganic quartzite plates are generally produced by the pressing plate method, but the cost is high.

The inorganic artificial stone and the organic artificial stone have different material components and different preparation methods. The organic artificial stone is mainly bonded by resin, has better toughness, can be cut after being prepared into square materials, and is not easy to break edges, so the organic artificial stone can be prepared by a method for cutting after preparing the square materials. The inorganic artificial stone plate is not bonded by resin, and the common square material has large volume and large internal and external temperature difference. Therefore, in general, if the inorganic artificial stone plate is prepared by the square stock cutting method, the risk of edge chipping or deformation cracking is easy to occur during the preparation process, so that the method is not popular in preparing the inorganic artificial stone plate in the industry.

The invention adjusts the formula of the inorganic artificial stone material composition, designs reasonable component proportion and enables the composition to be prepared by a square material cutting method. The problems caused by the traditional pouring method or the pressing plate method for preparing the inorganic artificial stone plate can be avoided. For example, the prepared plate has compact structure and low preparation cost.

The technical scheme is as follows:

Optionally, the inorganic gel material is white cement. Specifically, albo brand white cement (p.w42.5) can be selected.

Optionally, the active aggregate is selected from at least one of white silica fume, kaolin and lime, and the particle size of the active aggregate is 0.1-0.5 μm.

Optionally, the sand is selected from at least one of carbonate machine sand and quartz sand.

Optionally, the auxiliary agent is a water reducing agent. The water reducing agent can be selected as the nican water reducing agent (solid content is 45%).

Optionally, the filler is ground calcium carbonate.

The inorganic artificial stone material composition is firstly pressed into a square material, and at the moment, through the adjustment of the composition formula, the square material has good toughness and high bending strength, is not easy to break edges and damage after cutting, and meanwhile, the good toughness can resist the cracking risk caused by the temperature difference between the inside and the outside of the square material. The substrate is obtained after cutting, and then the patterns are transferred by ink permeation to form a cover coat layer, so that the inorganic artificial stone plate with the appearance and texture of natural stone and clear texture can be prepared. The formulation cost of the above composition is 1/2 stone, 2/3 for tile system. Meanwhile, compared with the traditional pouring method, the prepared inorganic artificial stone plate has the advantages of compact structure, high bending strength (more than 10MPa), good impact resistance and 2/3-th preparation cost of the pouring method. Compared with a pressing plate method, the preparation cost is reduced by half while the high performance is maintained. Through ink-bleeding printing, compared with ink which is UV printing attached to the surface of a product, the ink permeates into the surface of the plate, the color fastness is strong, the color is stable and not easy to fade, the natural texture is more vivid, the surface smoothness is high, and the environment is protected. The wear resistance, moisture resistance and acid and alkali resistance of the plate are ensured through the cover coat.

It will be appreciated that in one embodiment, the mix is a mix of ultra high performance concrete, UHPC.

After a mixture is obtained, pressing the mixture into a square material and then cutting to obtain a substrate;

optionally, the vibration current of the pressing is 165A + -2A, and the vibration speed is 2500RPM + -100 RPM.

Optionally, the dimensions of the billet comprise: the length is 2200mm-2700mm, the width is 1200mm-1800mm, and the height is 800mm-1200 mm. . Specifically, optionally, the square stock is a rectangular parallelepiped with a length of 2700mm, a width of 1800mm and a height of 1000 mm.

In one embodiment, the billet may be cut into thin slabs of 2700mm long by 1800mm wide by 15 mm.

Optionally, the method further comprises grinding and polishing steps after the cutting, and the substrate is prepared.

The substrate may have a gloss of 70 to 90 and a mohs hardness of 4 to 6.

It is understood that the substrate is a white substrate.

Optionally, the method for ink-bleed transferring the pattern on the substrate comprises:

It will be appreciated that bleed printing may be output printing as described above in a bleed printer.

The ink-bleed printing described above uses a piezoelectric ink-bleed technique, in which ink is ejected from a nozzle similar to a thermal ink-jet technique, but ink droplets are formed by reducing the area from which ink is ejected. The reduction of the ejection area is controlled by applying a voltage to one or more piezoelectric plates within the ejection area. The micro-piezoelectric printing head technology utilizes the discharge characteristic when a crystal is pressurized, and ink is stably ejected at normal temperature. The ink drop control capability is strong, the printing quality with high definition and high precision can be realized, heating is not needed during micro-piezoelectric ink jet, the ink can not generate chemical change due to heating, and the color fidelity is improved.

It can be understood that the side of the drawing with the predetermined pattern is attached to the substrate and may be fixed with an adhesive tape.

Optionally, applying a temperature of 180 ℃ to 300 ℃ to cause penetration transfer of the ink onto the substrate.

After the drawing is removed, the ink infiltration plate with the resolution of 300dpi, rich pattern layers, bright colors and small color difference can be formed.

The surface textures of the artificial stone are prepared by the pigments, the types of the textures are not flexible, and the plates with complex textures cannot be prepared basically (or the technical difficulty is high and the cost is high). The invention adopts the ink-bleeding printing mode, can print on the UHPC white substrate and can realize the printing of various textures. Various patterns can be randomly customized according to the design requirements, and the requirements of different consumers are met. The ink-bleeding printing plate not only keeps the noble and elegant characteristics of natural stone, but also has the characteristics of bright color and luster and the like. Compared with UV printing (ink is attached to the surface of a product), ink-bleeding printing is to print patterns on a material, and the ink permeates into the surface of a plate, so that the color fastness is strong, a paint film is plump, the surface smoothness is high, the environment is protected, and the like.

And forming an overcoat layer on the ink-permeating plate. Optionally, the raw material of the overcoat is selected from fluorocarbon varnish, polyurethane varnish, or acrylic varnish. The hardness is higher than that of UV gloss oil. Preferably, the material of the overcoat is selected from fluorocarbon varnish, which has low surface energy and extremely low friction coefficient because fluorine atoms in the fluorocarbon varnish have the highest electronegativity, smaller atomic radius and F-C bond is the most stable of all chemical bonds. The inorganic artificial stone plate with the fluorocarbon coating has the advantages of super-long weather resistance, excellent light and color retention, acid resistance of 48H, alkali resistance of 72H, oil resistance of 72H, corrosion resistance and self-cleaning property, and is high in surface hardness (pencil hardness is more than or equal to 3H), good in wear resistance (less than or equal to 0.03g), good in water resistance (168H does not blister or fall off), good in impact resistance (1000g of steel ball, and a paint film is free of cracks and peeling), and high in glossiness.

The top coating can be prepared by spraying or rolling the raw materials for multiple times, and the thickness of each spraying or rolling coating is 0.2mm-0.5 mm.

It will be appreciated that spraying or rolling is continued after one surface drying.

Specifically, the fluorocarbon varnish can be Daisen F55-7 type, the polyurethane varnish can be three-tree polyurethane varnish SGM400 and SGM500, and the acrylic varnish can be Zhejiang bridge acrylic varnish.

The inorganic artificial stone plate can be used as an integrated kitchen and bathroom decorative plate.
