Detailed Description

Before the three-dimensional multilayer ceramic patch of the present invention is described in detail in the present embodiment, it is to be noted that similar elements will be denoted by the same reference numerals in the following description. The drawings of the present invention are for illustrative purposes only and are not necessarily to scale, nor are all details thereof presented in the drawings.

First, the technique of the present invention can be applied to any ceramic patches for decoration or other purposes, such as nail patches, wall tiles, and mobile phone case patches.

Please refer to fig. 1, which is a schematic diagram illustrating a first embodiment of the present invention. As shown in the figure, the three-dimensional laminated ceramic patch 1 of the present embodiment is formed by stacking a plurality of ceramic thin layers 2 layer by layer, the plurality of ceramic thin layers 2 includes a first ceramic thin layer 21 and a second ceramic thin layer 22, and the color and transmittance of the first ceramic thin layer 21 are different from those of the second ceramic thin layer 22. In this embodiment, the color and transmittance of the plurality of ceramic thin layers 2 are different from each other, that is, the color and transmittance of each ceramic thin layer 2 are different.

To explain further, the ceramic patch 1 of the present embodiment includes the cut end portion 44 and the neck portion 45, and the ceramic laminate body 2 located at the neck portion 45 has the darkest color, such as yellow, and the color gradually becomes lighter from the neck portion 45 toward the cut end portion 44, and the lightest color, such as white. The ceramic thin layer body 2 at the cut end 44 has the highest transmittance, and gradually decreases in transmittance toward the neck 45. Accordingly, the color and transmittance of each ceramic thin layer body 2 can be changed at will, and a gradually layered color and transmittance can be formed, so that natural teeth can be highly simulated, and personalized patterns can be directly formed according to requirements.

Referring to fig. 2 and 3 together, fig. 2 is a perspective view of a ceramic green sheet according to a first embodiment of the present invention, and fig. 3 is a structural view of a manufacturing apparatus according to the first embodiment of the present invention. The following describes the manufacturing process of the ceramic patch 1 of the present embodiment, and first describes the basic architecture of the manufacturing equipment used in the present embodiment, which includes a main controller 3, a slurry layer module 4, a slurry tank 40, a coloring and spraying module 5, a colorant tank 51, and a light curing module 6; the slurry tank 40 is filled with slurry prepared by blending zirconia powder, light-cured resin, solvent and additive; and the toner tank 51 is filled with toner.

Firstly, the main controller 3 controls the slurry layer laying module 4 to lay a slurry layer on a base station (not shown); then, the main controller 3 controls the coloring and spraying module 5 to spray coloring materials on the slurry layer; standing for several seconds, after the equal color material enters the slurry layer, the main controller 3 controls the illumination curing module 6 to illuminate the slurry layer for curing. Thus, the slurry layers are spread layer by layer, and after the pigment is sprayed on the slurry layers, the slurry layers are irradiated to be cured.

The change of the transmittance layer by layer can be achieved by adjusting the formula of the slurry in the slurry tank 40, for example, by gradually adding a light-transmitting slurry prepared from 6Y PSZ powder, a photocurable resin, a solvent and an additive as the process proceeds, thereby increasing the transmittance. However, the above steps are repeated, i.e. spreading the slurry layer, spraying and coloring, and curing by irradiation, to form the ceramic green sheet 11, and finally sintering the ceramic green sheet 11 at high temperature to form the ceramic patch 1.

In addition, as shown in fig. 1 and fig. 2, the thickness of each ceramic thin layer body 2 in the ceramic patch 1 of the present embodiment is 10 μm to 30 μm, preferably 20 μm; and the thickness of the ceramic patch 1 is 0.2mm to 0.8mm, preferably 0.5 mm. The ceramic patch 1 of the present embodiment includes the design surface 41 and the adhesion surface 42, and the surface roughness Ra of the adhesion surface 42 is larger than the design surface 41, and is preferably 0.1 μm or more.

Further describing the surface roughness Ra, the attachment surface 42 is provided with the anti-shedding microstructure 12, which is a stepped rough surface 43 formed by the edge portions of a plurality of ceramic thin layer bodies 2 stacked layer by layer. As shown in fig. 2, the ceramic green sheets 11 are stacked and formed by inclining at a specific angle θ, and the edge portions of the plurality of ceramic thin layer bodies 2 stacked and formed in this way will naturally form the step-shaped rough surface 43. Accordingly, the step-shaped rough surface 43 is beneficial to adhering adhesive, so as to improve the adhesion.

Referring to fig. 4A and 4B, fig. 4A is a schematic view of a second embodiment of the present invention, and fig. 4B is a cross-sectional view taken along line a-a in fig. 4A. The main difference between this embodiment and the previous embodiments is that the anti-peeling microstructure 12 of this embodiment is formed by the recessed portion 13, i.e. by the plurality of dovetail grooves 15, the dovetail grooves 15 can form strong holding force to the adhesive, and the adhesive is not easy to be peeled off once entering the dovetail grooves 15. The depth of the dovetail groove 15 may be 50 μm to 300 μm, and the width of the groove opening may be 1 to 3 times the depth, on the premise that it is not noticeable to the naked eye from the appearance surface 41. Further, since the light transmittance of the ceramic chip 1 is higher as it approaches the cut end portion 44, the dovetail groove 15 is preferably provided near the neck portion 45. However, the dovetail grooves 15 may be provided throughout the attachment surface 42, but the depth of the dovetail grooves 15 may become gradually shallower as it approaches the tangential end 44.

Please refer to fig. 4C, which is a schematic diagram of a third embodiment of the present invention; the embodiment is mainly used to show that the anti-peeling microstructure 12 may also adopt a mode of the protrusions 14, i.e. circular bumps and wave-shaped raised strips as shown in the figure, and the height of the protrusions 14 may be 50 μm to 300 μm. In addition, the anti-shedding microstructure 12 may be in the form of a text or other geometric figures, such as the fourth embodiment shown in fig. 5A and the fifth embodiment shown in fig. 5B.

Referring to fig. 6A and 6B, fig. 6A is a schematic diagram of a sixth embodiment of the present invention, and fig. 6B is a cross-sectional view taken along line B-B in fig. 6A. The main difference between this embodiment and the foregoing embodiments is that in this embodiment, colored regions with different colors may be additionally disposed in the single ceramic thin layer body 2; when multiple layers are stacked, a specific pattern can be formed.

To explain, as shown in fig. 6B, the ceramic laminate 2 includes three first colored regions 31 and two second colored regions 32; the color and transmittance of the first colored region 31 can be set as in the first embodiment, but the color of the second colored region 32 can be red or pink; stacked in this manner, the second colored region 32 can form a cherry blossom pattern as shown in fig. 6A.

The above-described embodiments are merely exemplary for convenience of description, and the scope of the claims of the present invention should not be limited to the above-described embodiments.
