Description

Technical Field

[0001] This application belongs to the field of jewelry technology, specifically relating to a jewelry accessory and jewelry. Background Technology

[0002] Natural gemstones, with their unique colors, luster, and rarity, are widely used in jewelry and high-end products, making them highly sought after by consumers. However, natural gemstones also have drawbacks such as scarcity, high prices, and the tendency for settings to fall out, which limit their further application.

[0003] Traditional lacquered jewelry, with its fashionable and avant-garde characteristics, aligns with the aesthetic preferences of young consumers. The lacquering process allows for the creation of jewelry with unique designs and color combinations, satisfying the fashion and individualistic demands of young consumers. However, traditional lacquered jewelry also has some drawbacks, such as: a lack of three-dimensionality; the smooth, flat lacquer surface fails to achieve the three-dimensional effect of natural gemstones or vibrant colors, resulting in a relatively monotonous overall visual effect; susceptibility to oxidation and discoloration; prolonged exposure to air causes the lacquer layer to oxidize, leading to fading and reduced gloss; and a cheap appearance; due to the lack of three-dimensionality, products made with traditional lacquering often give a cheap impression, making it difficult to enhance the product's added value.

[0004] With consumers increasingly demanding more diverse and high-quality jewelry, traditional lacquered jewelry can no longer meet market needs. Utility Model Content

[0045] [Jewelry and Accessories]

[0046] In a first aspect, embodiments of this application provide a jewelry accessory. In some embodiments, the jewelry accessory of this application includes a substrate, a colored layer, and a light-transmitting encapsulation layer; wherein, the substrate has a concave surface; the colored layer has a concave surface and a convex surface, and the convex surface of the colored layer is disposed opposite to the concave surface of the colored layer, and the convex surface of the colored layer is in contact with the concave surface of the substrate; the light-transmitting encapsulation layer covers the concave surface of the colored layer.

[0047] In the jewelry accessories of this application embodiment, the substrate is a component used to support the colored layer; the colored layer is a pigment layer containing pigments, which gives the colored layer the corresponding color; the light-transmitting encapsulation layer refers to a layer structure that has light transmittance and can protect the colored layer.

[0048] Based on the components and their relationships described above, the jewelry accessories of this embodiment include the following structures in some embodiments: Figure 1 As shown, the base 10 of the jewelry accessory 01 has a concave surface 11; the convex surface 22 of the colored layer 20 is disposed opposite to the concave surface 21 of the colored layer 20, and the convex surface 22 of the colored layer 20 is attached to the concave surface 21 of the base 10; the light-transmitting encapsulation layer 30 covers the concave surface 21 of the colored layer 20.

[0049] Thus, the concave surface of the substrate in the jewelry accessories of this application not only provides positioning and support for the colored layer, but more importantly, it can adjust the morphology of the colored layer and the distribution of the pigments contained in the colored layer through the shape and depth of the concave surface of the substrate. Simultaneously, based on the tiny size and special structure of the pigments contained in the colored layer, they can produce multi-angle light reflection and refraction effects. Based on the bonding relationship between the colored layer and the concave surface of the substrate, the two can achieve a synergistic effect of optical reflection, allowing the colored layer to exhibit rich color changes and a three-dimensional light effect at different angles, giving the jewelry accessories a gem-like texture. The light-transmitting encapsulation layer not only effectively prevents damage to the colored layer from the external environment and improves its color stability and durability, but also further adjusts and optimizes the light reflected by the colored layer through its light-transmitting properties. This adjustment not only enhances the three-dimensional light effect and gem-like texture of the jewelry accessories, but also makes the overall visual effect more delicate and layered.

[0050] Therefore, the jewelry accessories in this application embodiment achieve comprehensive optimization of color, luster and texture through the synergistic effect of the concave surface of the substrate, the colored layer and the light-transmitting encapsulation layer, so that the jewelry accessories have a three-dimensional light effect and gemstone texture, and can also make their color and luster stable and lasting.

[0051] Matrix:

[0052] The dimensions of the base and concave surface of the base in the jewelry accessories of this application embodiment can be flexibly adjusted according to the size of the jewelry accessories. In some embodiments, the curvature of the concave surface of the base can be 0.1 / R to 0.75 / R. In exemplary examples, it can be typical but non-limiting curvatures such as 0.1 / R, 0.2 / R, 0.3 / R, 0.4 / R, 0.5 / R, 0.6 / R, 0.7 / R, and 0.75 / R, or any range between two curvature values. The curvature of the concave surface refers to the degree of bending of the concave surface, that is, the degree to which the surface deviates from the plane at various points on the concave surface. The curvature of the concave surface can be understood as the average curvature of the concave surface. R in 0.1 / R to 0.75 / R is the radius of the concave surface. The above-mentioned curvature range of the concave surface can indirectly adjust the concave surface of the colored layer, such as... Figure 1 The curvature of the medium surface 21 is adjusted to regulate the morphology of the colored layer and the distribution of the pigments contained in the colored layer, so as to adjust the color, three-dimensional light effect and gem-like texture of the colored layer.

[0053] In some embodiments, the concave surface of the substrate is formed by joining multiple planar surfaces. For example, in some embodiments... Figure 2 As shown, the concave surface 11 of the substrate 10 is formed by splicing together multiple planes 111. Figure 2In the concave surface 11 of the substrate 10 shown, the concave surface 11 is divided into multiple planar regions by planes 111, and these planar regions are joined together to form the concave surface 11. Here, "planar" refers to a plane with zero curvature. By setting the concave surface 11 of the substrate 10 as multiple planes 111, which serve as the support surface for the colored layer, the convex surface of the colored layer can be made to appear as... Figure 1 The convex surface 21 of the colored layer 20 is also divided into multiple corresponding planar regions, so that the colored layer also has multiple reflective light planes, which makes the colored layer produce multi-angle light reflection and refraction effects, and can show rich color changes and three-dimensional light effects at different angles.

[0054] In the embodiment, when the concave surface of the substrate is composed of multiple planes joined together, a single plane is as follows: Figure 2 The area S of a single plane 111 can occupy 1 / 20 to 1 / 3 of the total area of ​​the concave surface, optionally 1 / 17 to 1 / 15. In the example, it can be a typical but non-limiting area ratio such as 1 / 20, 1 / 18, 1 / 17, 1 / 15, 1 / 13, 1 / 11, 1 / 10, 1 / 9, 1 / 7, 1 / 15, 1 / 3, or a range between any two area ratio values. In the embodiment, the area of ​​the concave surface of the substrate can be π mm. 2 ~25πmm 2 Optionally, it can be 1πmm 2 ~16πmm 2 .

[0055] In the embodiment, when the concave surface of the substrate is formed by splicing together multiple planes, the planes are as follows: Figure 2 The number of midplanes 111 includes 3 to 20, optionally 15 to 17. In the example, it can be a typical but non-restrictive area or a range between any two area values, such as 3, 5, 7, 9, 10, 11, 13, 15, 17, 18, 20.

[0056] By controlling the area ratio of a single plane in the concave surface of the substrate within the above-mentioned range or by controlling the number of planes in the concave surface of the substrate within the above-mentioned range, the structure of the colored layer can be further indirectly adjusted, thereby adjusting the multi-angle light reflection and refraction effect of the colored layer and optimizing color changes and three-dimensional light perception.

[0057] In some embodiments, the substrate includes a cured adhesive matrix. These substrates possess good structural stability, effectively positioning and supporting the colored layer. Furthermore, the color of the substrate can be adjusted by selecting the type of substrate as needed to achieve a color matching effect with the colored layer. As in the embodiments, when the substrate includes a cured adhesive matrix, this cured adhesive matrix can be prepared from the material used to prepare the substrate in the jewelry accessory preparation method of the following embodiments.

[0058] Colored layer:

[0059] In the jewelry accessories of this application embodiment, the colored layer is a key structural and functional layer that imparts color, three-dimensional light and visual effects to the jewelry accessories.

[0060] In some embodiments, the colored layer can be bonded to the concave surface of the substrate to improve the bonding strength between the colored layer and the substrate.

[0061] In some embodiments, the thickness of the colored layer is 5nm to 5mm, optionally 5nm to 3mm. In exemplary cases, it can be a typical but non-limiting thickness such as 5nm, 10nm, 50nm, 100nm, 300nm, 500nm, 800nm, 1μm, 3μm, 5μm, 7μm, 1mm, 2mm, 3mm, 4mm, 5mm, or any range between two thickness values. Controlling the thickness of the colored layer within this range can improve its light reflectivity. For example, in some embodiments, the light reflectivity R of the colored layer is >80%. This high light reflectivity enhances the color, three-dimensional light effect, and other visual effects of the colored layer.

[0062] In some embodiments, the colored layer is composed of multiple planar colored layer units joined together. Specifically, as shown below... Figure 3 As shown, the colored layer 20 is composed of multiple planar colored layer units, that is, the colored layer 20 is divided into multiple planar colored layer units. Here, each planar colored layer unit in the colored layer 20 refers to a planar colored layer whose individual plane 211 has a curvature of 0. At this time, combined with... Figure 1 and Figure 3 The concave surface 21 of the color layer 20 is formed by splicing together multiple planes 211 corresponding to the number of planar colored layer units. That is, in the concave surface 21 of the colored layer 20, the concave surface 21 is divided into multiple planar regions by planes 211, and each plane 211 is spliced ​​together to form the concave surface 21. Similarly, the convex surface 22 of the colored layer 20 is formed by splicing together multiple planes 221 corresponding to the number of planar colored layer units. That is, in the convex surface 22 of the colored layer 20, the convex surface 22 is divided into multiple planar regions by planes 221, and each plane 221 is spliced ​​together to form the concave surface 22.

[0063] In the embodiment, when the colored layer 20 is as Figure 3 The structure shown is composed of multiple planar colored layer units, and the concave surface 11 of the substrate 10 is as described above. Figure 2 When the substrate 10 is also composed of multiple planes 111, each plane 111 in the concave surface 11 of the substrate 10 has a planar colored layer unit of colored layer 20 stacked on it, such as... Figure 3As shown. In this way, the interfaces of individual planar colored layer units of colored layer 20 and each plane 111 in the concave surface 11 of substrate 10 are adapted and closely fitted, improving the structural stability of both. More importantly, the colored layer 2 is divided into reflective layer regions of multiple planar colored layer units, and the surfaces of multiple planar colored layer units facing away from substrate 10 constitute multiple light-reflecting surfaces, giving the colored layer 20 multi-angle light reflection and refraction effects, which can exhibit rich color changes and three-dimensional light effects at different angles.

[0064] In some embodiments, the colored layer in the above embodiments is a nanostructured color powder layer. This nanostructured color powder layer is a layered structure formed from nanostructured color powder. The nanostructured color powder includes sheet-like particles, each sheet-like particle comprising a first color powder layer and a second color powder layer, and the first and second color powder layers are alternately stacked and combined, with different refractive indices. The alternating stacking and combination of the first and second color powder layers means that the color powder layers are stacked and combined along one extending direction. Setting the nanostructured color powder as sheet-like particles, and having each sheet-like particle comprise multiple layers of color powder with different refractive indices stacked together, effectively enhances the light reflectivity of the nanostructured color powder, improves the brightness of the colored layer, and enriches the visual effects of color variation and three-dimensional light perception.

[0065] In this embodiment, when the sheet-like nanostructured color powder comprises sheet-like particles of an alternatingly stacked first color powder layer and a second color powder layer, the difference in refractive index between the two layers is greater than or equal to 0.2. In this embodiment, the thickness of each layer in the first and second color powder layers can be in the nanometer range. Further optimizing the difference in refractive index between the two color powder layers and the thickness of the monochromatic color powder layer within this range can further improve the light reflection and refractive index of the nanostructured color powder, enhance the brightness and color variation richness of the colored layer, and improve visual effects such as stereoscopic light perception.

[0066] In this embodiment, the material of the first color powder layer may include at least one high-refractive-index material selected from oxides, sulfides, etc. In an example, the oxide may include at least one selected from titanium oxide, zirconium oxide, aluminum oxide, tantalum oxide, and hafnium oxide, and the sulfide may include, but is not limited to, zinc sulfide. In this embodiment, the material of the second color powder layer may include at least one low-refractive-index material selected from silicon monoxide, silicon dioxide, magnesium fluoride, calcium fluoride, and sodium aluminate hexafluoride. By selecting the materials of the first and second color powder layers, the stability and richness of the color of the color powder layer can be improved, and the visual effects such as the color brightness and rich color variations of the nanostructured color powder can also be enhanced.

[0067] Based on the material embodiments of the first and second color powder layers described above, in these embodiments, the thickness of the first color powder layer can be 30–1000 nm, and the thickness of the second color powder layer can be 40–1000 nm. Further controlling the thicknesses of the two color powder layers within these ranges, based on the materials of the first and second color powder layers, can further improve the light reflectivity of the nanostructured color powder, thereby enhancing visual effects such as color brightness and rich color variations.

[0068] In some embodiments, the particle size of the nanostructured pigments contained in the colored layer in the above embodiments is 5nm to 80nm, optionally 5nm to 20nm. In exemplary examples, it can be a typical but non-limiting particle size such as 5nm, 10nm, 20nm, 30nm, 40nm, 50nm, 60nm, 70nm, 80nm, or any range between two particle size values. When the nanostructured pigment particles are in the above-mentioned sheet-like shape, the length of the sheet-like particles can be 5nm to 80nm, the width can be 5nm to 80nm, and the thickness of the sheet-like particles can be determined by the number of pigment layers they contain. For example, the thickness of the sheet-like particles can be less than their length. The particle size of the nanostructured pigments enables the nanostructured pigments to have a relatively small light-reflecting surface, thereby improving the visual effects such as rich color variations and three-dimensional light perception that the colored layer exhibits during light reflection.

[0069] In some embodiments, the colored layer in the above embodiments further includes a binder, the mass ratio of which to the pigment in the colored layer, such as the aforementioned nanostructured color powder, is 1:(1-2). Adding a binder to the colored layer can enhance its structural strength. Simultaneously, controlling the mass ratio of the binder to the pigment, such as the nanostructured color powder, within this range enhances the structural stability of the colored layer and improves the rich color variations and three-dimensional light-reflecting visual effect exhibited by the colored layer at different angles.

[0070] Transparent encapsulation layer:

[0071] In the jewelry accessories of this application embodiment, the light-transmitting encapsulation layer serves to protect the colored layer and can also adjust the reflected light of the colored layer, thereby adjusting the visual effects such as the three-dimensional light effect and gemstone texture of the jewelry accessories.

[0072] In some embodiments, the surface of the light-transmitting encapsulation layer facing away from the colored layer is convex. In this case, the convex surface can serve as the outer surface of the light-transmitting encapsulation layer or the light-emitting surface of the colored layer reflecting light. Setting the outer surface of the light-transmitting encapsulation layer as convex can effectively increase the light-emitting surface area and the light-emitting angle, thereby enhancing the visual effect of the three-dimensional light perception of the jewelry accessories.

[0073] In some embodiments, the morphology of the light-transmitting encapsulation layer is as follows: Figure 1 and 3As shown, the light-transmitting encapsulation layer 30 is a convex mirror, having a convex surface 31 and another convex surface 32 opposite to the convex surface 31. In this case, the convex surface 31 can be bonded to the concave surface 21 of the colored layer 20. This ensures a tight fit between the light-transmitting encapsulation layer 30 and the concave surface 21 of the colored layer 20, enhancing the bonding strength between them. Furthermore, the other convex surface 32 of the light-transmitting encapsulation layer 30 effectively increases the light-emitting surface area and the light-emitting angle, improving the visual effect of the three-dimensional light perception of the jewelry accessories.

[0074] In some embodiments, the convex surface of the light-transmitting encapsulation layer facing away from the colored layer comprises multiple planar surfaces joined together. In embodiments, such as... Figure 1 and Figure 3 As shown, the convex surface 32 of the light-transmitting encapsulation layer 30 is formed by splicing together multiple planes 321. That is, in the convex surface 32 of the light-transmitting encapsulation layer 30, the convex surface 32 is divided into multiple planar regions by multiple planes 321, and each plane 321 is spliced ​​together to form the convex surface 32. By setting the convex surface 32 of the light-transmitting encapsulation layer 30 away from the colored layer as multiple planes 321, the light-transmitting encapsulation layer 30 has multiple light-emitting surfaces that reflect light, which can work synergistically with the colored layer 20 to improve the visual effect of the jewelry accessories of this application having multi-angle light reflection and refraction effects and three-dimensional light sense.

[0075] In some embodiments, combined with Figure 1 ,like Figure 3 As shown, the convex surface 31 of the light-transmitting encapsulation layer 30 is adapted to the interface morphology of the colored layer 21, and the two surfaces are tightly bonded. At this time, the convex surface 31 is also composed of multiple planes spliced ​​together; that is, within the convex surface 31 of the light-transmitting encapsulation layer 30, the convex surface 31 is also divided into multiple planar regions by multiple planes. In this way, the structural stability of both the light-transmitting encapsulation layer 30 and the colored layer 20 is effectively improved, enhancing the structural and morphological stability of the colored layer 20. This, in turn, improves the multi-angle light reflection and refraction effect and the three-dimensional light effect of the colored layer 20, thus enhancing the visual effect of the jewelry accessories of this embodiment having multi-angle light reflection and refraction effects and a three-dimensional light effect.

[0076] In the example, the surface of the light-transmitting encapsulation layer facing away from the colored layer is convex, and this convex surface is a gemstone surface, such as... Figure 3 The convex surface 32 of the light-transmitting encapsulation layer 30 shown is a gemstone surface. This gemstone surface can be a diamond surface. This gives the jewelry accessory a high-quality gemstone appearance.

[0077] In this embodiment, the material of the light-transmitting encapsulation layer can be at least one of silica, transparent resin, glass, or gemstone. The transparent resin may include, but is not limited to, polymethyl methacrylate. These light-transmitting encapsulation layers possess good transparency and mechanical strength, and can protect the colored layer, improving the stability of the colored layer's shape and color. When the material of the light-transmitting encapsulation layer is glass or gemstone, it can create a visually synergistic effect with the colored layer, enhancing its three-dimensional light perception.

[0078] [Preparation method of the above-mentioned jewelry accessories]

[0079] In some embodiments, the jewelry accessories described in the above application can be prepared according to a preparation method including the following steps:

[0080] S10: Provide a substrate with a concave surface;

[0081] S20: Forming a colored layer of pigment on the concave surface of the substrate;

[0082] S30: A light-transmitting encapsulation layer is formed on the surface of the colored layer away from the substrate using a light-transmitting encapsulation material, encapsulating the outer surface of the colored layer to form an accessory.

[0083] The method for preparing jewelry accessories in this application can effectively form a colored layer on the concave surface of the substrate, which can make the colored layer have a bowl-shaped structure with relatively set convex and concave surfaces. Under the action of the colored layer structure and pigment, the formed colored layer can produce multi-angle light reflection and refraction effects. With the synergistic effect of the substrate and the light-transmitting encapsulation layer, the prepared jewelry accessories can exhibit rich color changes and three-dimensional light effects from different angles.

[0084] Step S10:

[0085] The substrate in step S10 is the same as the substrate of the jewelry accessory in the above-described application embodiment. Therefore, the concave surface of the substrate is also the same as the concave surface of the substrate of the jewelry accessory in the above-described application embodiment. Figure 1 and Figure 2 The concave surface 11 of the substrate 10.

[0086] In this embodiment, the substrate can be prepared using the following method:

[0087] After mixing agent A and agent B in a certain proportion, the mixture is molded to form a substrate preform with a concave surface, and then cured to obtain the substrate.

[0088] In this embodiment, Agent A and Agent B can be conventional two-component adhesives or AB adhesives. Agent A includes propylene oxide or ethylene oxide; Agent B can include at least one of alcohols, ketones, esters, etc. When Agent A and Agent B are mixed, they exhibit a certain degree of fluidity, allowing for efficient formation of a matrix preform. The alcohols, ketones, and esters in Agent B act as curing agents, causing Agent A to cure. Simultaneously, the alcohols, ketones, and esters in Agent B also act as solvents, effectively mixing and dispersing Agent A within Agent B, improving the uniformity of the mixture and thus enhancing the structural and shape stability of the matrix preform. This matrix preform can have a concave structure, resulting in a concave matrix after curing. The matrix prepared by this method exhibits good structural stability and mechanical strength, improving the structural stability of the prepared jewelry accessories.

[0089] When the concave surface of the substrate is as follows Figure 2 and Figure 3 When multiple planes 111 are shown, the concave surface of the substrate blank can be shaped, such as by shaping to form... Figure 2 and Figure 3 The concave surface 11 shown has multiple planes 111. The shaping process can be mold forming or polishing, etc.

[0090] In the embodiments, the curing process may be performed by irradiating with ultraviolet light and by vacuum treatment to smooth the substrate surface, including concave surfaces.

[0091] Step S20:

[0092] In step S20, the formed colored layer is as described in the above text application embodiment where the jewelry accessory has a colored layer, such as... Figure 1 and Figure 3 The colored layer 20 in the middle.

[0093] In some embodiments, the method for forming a colored layer involves mixing pigment and binder on the concave surface of the substrate to form a colored layer structure. Alternatively, before the substrate preform in step S10 cures, the pigment can be directly applied to the concave surface of the substrate preform, and then cured. During the curing process of the substrate preform, the pigment is directly fixed to the concave surface of the substrate, thereby forming a colored layer.

[0094] In this embodiment, the pigment may include nanostructured color powder. This nanostructured color powder may be commercially available. In this embodiment, when the nanostructured color powder is a sheet-like nanostructured color powder including the first and second color powders mentioned above, composite color powder films can be prepared according to the color powder layer structure and the material of each color powder layer in the sheet-like nanostructured color powder, and then granulated to obtain the sheet-like nanostructured color powder.

[0095] Step S30:

[0096] In step S30, the formed light-transmitting encapsulation layer is as described in the above-described embodiment of the jewelry accessory light-transmitting encapsulation layer. Figure 1 and Figure 3 The light-transmitting encapsulation layer 30 in the middle.

[0097] In some embodiments, the method of forming a light-transmitting encapsulation layer on the surface of a colored layer away from the substrate using a light-transmitting encapsulation material may include the following steps:

[0098] S31: A transparent encapsulation material is formed by mixing agent C and agent D in a certain proportion;

[0099] S32: A light-transmitting encapsulation material is formed on a concave surface including a colored layer and then cured to form a light-transmitting encapsulation layer that at least covers the concave surface of the colored layer.

[0100] In this embodiment, agent C and agent D in step S31 can be conventional two-component adhesives or AB adhesives. In this embodiment, agent C in step S31 includes epoxy alkyl resins or epoxy alkyl resin monomer components; agent D includes at least one of amines, acids, phenolic resins, etc. Based on the components of agent C and agent D, in this embodiment, agent C and agent D are mixed in a mass ratio of 1:(1-2). In the exemplary example, the mass ratio of agent C and agent D can be 1:1, 1:2, etc. After the light-transmitting encapsulation material formed by mixing the above-mentioned component types and mixing ratio ranges including agent C and agent D is cured in step S32, the light-transmitting encapsulation layer achieves a glassy effect, and has good anti-aging properties, high hardness, and wear resistance.

[0101] In the examples, the centipoise viscosity (CPS@25℃) of agent C can be 150000±20000 mPa·s, and the centipoise viscosity (CPS@25℃) of agent D can be 150000±20000 mPa·s. The light-transmitting encapsulation material formulated with agents C and D within this viscosity range exhibits good film-forming properties, which can improve the quality and optical performance of the light-transmitting encapsulation layer.

[0102] In some embodiments, the components and mixing ratio of agent C and agent D can be controlled and adjusted to allow the prepared light-transmitting encapsulation material to have different curing times. Moreover, the curing time of the light-transmitting encapsulation material varies with temperature, and the color of the light-transmitting encapsulation material also changes during this process. That is, the film layer state formed by the film-forming treatment of the light-transmitting encapsulation material in step S31 is different at different curing times.

[0103] As in the embodiments, the components of agent C may include epoxy alkyl groups, and the components of agent D may include phenolic resin. When the mass ratio of agent C and agent D is 1:1, the light-transmitting encapsulation material can be heated to the ambient temperature of 50°C by ultraviolet light for 5 minutes. The film layer formed by the film-forming treatment of the light-transmitting encapsulation material has adhesiveness, solidifies on the outside, and is liquid inside.

[0104] In the embodiments, the components of agent C include epoxy alkyl groups, the components of agent D include phenolic resin, and when the mixing mass ratio of agent C and agent D is 1:1, the light-transmitting encapsulation material can be heated to the ambient temperature of 50°C and maintained for 30 minutes by ultraviolet light. The film layer formed by the film-forming treatment of the light-transmitting encapsulation material has adhesiveness, solidifies on the outside and is semi-solid inside.

[0105] In the embodiment, the components of agent C include epoxy alkyl groups, and the components of agent D include phenolic resin. When the mass ratio of agent C to agent D is 1:1, the light-transmitting encapsulation material can be heated to the ambient temperature of 50°C and maintained for 60 minutes by ultraviolet light. The film layer formed by the film-forming process of the light-transmitting encapsulation material solidifies on both the outer surface and the interior, and is milky white.

[0106] In the embodiment, the components of agent C include epoxy alkyl groups, and the components of agent D include phenolic resin. When the mass ratio of agent C to agent D is 1:1, the light-transmitting encapsulation material can be heated to the ambient temperature of 50°C and maintained for 120 minutes by ultraviolet light. The film layer formed by the film-forming process of the light-transmitting encapsulation material solidifies both the outer surface and the interior, and is transparent and glassy.

[0107] In this embodiment, during the film-forming process, the surface of the film layer facing away from the colored layer can be shaped and cured. After the film layer is cured, the outer surface of the light-transmitting encapsulation layer, i.e., the surface facing away from the colored layer, can be given a specific morphology, such as... Figure 3 The film has multiple convex surfaces with planes. The shaping and curing process involves placing a model on the outer surface of the film. After the film has cured, it is demolded, so that the outer surface of the light-transmitting encapsulation layer has a shape consistent with the model.

[0108] In addition to using a shaping and curing process to solidify the film layer formed by the film-forming process of the light-transmitting encapsulation material, grinding and / or cutting processes can also be used to give the light-transmitting encapsulation layer specific properties, such as... Figure 3 The material has a convex topography with multiple planar surfaces. Therefore, in the embodiment, after step S32 in the method of forming a light-transmitting encapsulation layer on the surface of the colored layer away from the substrate using a light-transmitting encapsulation material, the following step S33 is further included:

[0109] S33: Grind and / or cut the outer surface of the film layer formed by curing in step S32.

[0110] By polishing and / or cutting in step S32, the outer surface of the cured light-transmitting encapsulation material film can be made to have specific characteristics, such as... Figure 3 It has a convex shape with multiple planes. The polishing and / or cutting can be done using polishing and / or cutting techniques commonly used in the field of jewelry design.

[0111] In an embodiment, when the light-transmitting encapsulation layer is made of other materials, such as glass or gemstones, the glass or gemstone material can be cut and polished to form the required size and shape before being bonded to the surface of the colored layer.

The jewelry of this application includes a jewelry body and jewelry accessories disposed on the jewelry body; wherein, the jewelry accessories include the jewelry accessories of the above-described application embodiments or the jewelry accessories prepared by the jewelry accessory preparation method of the above-described application embodiments. Thus, because the jewelry of this application includes the jewelry accessories of the above-described application embodiments, the jewelry accessories contained in the jewelry can exhibit rich color changes and three-dimensional light effects from different angles, thereby improving the quality of the jewelry of this application, increasing its added value, and enhancing its diversity.

[0114] In some embodiments, such as Figure 4 As shown, the jewelry body 02 of this embodiment has a groove, and the jewelry accessory 01 is embedded in the groove of the jewelry body 02, with the base 10 of the jewelry accessory 01 in contact with the bottom of the groove.

At this time, the base color layer 40 is disposed between the jewelry accessory 01 and the bottom of the jewelry body 02. Adding a base color layer 40 to the bottom of the groove allows the color in the base color layer 40 to overlap with the color layer 20 in the jewelry accessory 01. After light reflection and refraction, this allows the jewelry accessory 01 and the jewelry of this embodiment to exhibit a specific color.

[0116] In this embodiment, the thickness of the base color layer 40 can be from 1 nm to 5 mm. This thickness range enhances the color overlay effect between the base color layer 40 and the colored layer 20 in the jewelry accessory 01. Specifically, the thickness of the base color layer 40 can be adjusted according to the desired color and the designed color, thereby adjusting the specific color of the jewelry in this embodiment.

[0117] In the example, the pigment of the base color layer 40 can be a conventional pigment in the jewelry industry. In order to enhance the stability and strength of the layer structure and the stability of the color development of the base color layer 40, the base color layer 40 may also contain a binder, which forms a mixture with the pigment.

Where specific techniques or conditions are not specified in the embodiments, they are performed according to the techniques or conditions described in the literature in this field or according to the product instructions. Reagents or instruments used, unless otherwise specified, are all conventional products that can be obtained commercially.

[0121] Example 1:

[0122] This embodiment provides a gold-inlaid jewelry piece, comprising a jewelry body with a groove on it. A jewelry accessory is disposed at the bottom of the groove and embedded within it. The jewelry body is made of gold. The jewelry accessory includes a cured adhesive matrix with a concave surface, which is bonded to the bottom of the groove. The natural color of the gold jewelry body forms the base color layer (golden yellow), and the concave surface of the cured adhesive matrix is ​​0.5 / R (where R is the radius of the concave surface of the cured adhesive matrix). A colored layer is layered on the concave surface of the cured adhesive matrix, and a translucent encapsulation layer, resembling a convex mirror, is encapsulated on the concave surface of the colored layer. The colored layer is 2 mm thick and contains sheet-like nanostructured color powder (sheet particles 10 nm long and 5 nm wide). The outer surface of the translucent encapsulation layer, facing away from the colored layer, exhibits a diamond-like appearance.

[0123] This embodiment provides a method for preparing gold-inlaid jewelry, including the following steps:

[0126] S2. Preparation of jewelry accessories:

[0127] S21. A concave base for the jewelry accessory is formed on the bottom surface of the groove:

[0128] After mixing propylene oxide-based agent A with an alkaline catalyst, alcohol-based agent B is added and mixed in a 1:1 mass ratio to obtain a mixed adhesive. 3D modeling is used to form a suitable concave substrate in the groove of the gold jewelry body, followed by curing.

[0129] S22. Forming a colored layer on the concave surface of the substrate:

[0130] A colored layer, typically 2 mm thick, is formed on the concave surface of the substrate formed in step S21 by the nanostructure powder and binder.

[0132] A mixed adhesive is obtained by mixing propylene oxide C agent and amine B agent in a 1:1 mass ratio. The mixed adhesive is then encapsulated on the concave surface of a colored layer. After curing, a light-transmitting encapsulation layer with opposing double convex surfaces in the shape of a convex mirror is formed. Finally, the convex surface of the light-transmitting encapsulation layer, which serves as the outer surface, is ground, polished, and cut to form a diamond-like outer surface with multiple planes.

[0133] Example 2:

[0134] This embodiment provides a gold-inlaid jewelry. The difference between this gold-inlaid jewelry and the gold-inlaid jewelry in Embodiment 1 lies in the concave surface of the cured adhesive matrix contained in the jewelry body, which is 0.1 / R (where R is the concave radius of the cured adhesive matrix).

[0135] Example 3:

[0136] This embodiment provides a gold-inlaid jewelry. The difference between this gold-inlaid jewelry and the gold-inlaid jewelry in Embodiment 1 lies in the concave surface of the cured adhesive matrix contained in the jewelry body, which is 0.75 / R (R is the concave radius of the cured adhesive matrix).

[0137] Example 4:

[0138] This embodiment provides a gold-inlaid jewelry. Compared to the gold-inlaid jewelry in Embodiment 1, this gold-inlaid jewelry differs in that the concave surface of the cured adhesive matrix contained in the jewelry body is composed of multiple small planar components, and the area of ​​each small planar component occupies 1 / 11 of the total concave surface area. The colored layer is also formed along the concave surface of the cured adhesive matrix; in this case, the concave surface of the colored layer also has the same number and area of ​​small planar components as the concave surface of the cured adhesive matrix.

[0139] Example 5:

[0140] This embodiment provides a gold-inlaid jewelry. Compared with the gold-inlaid jewelry in Embodiment 1, this gold-inlaid jewelry differs in that a base color layer is added to the bottom of the groove in the gold jewelry body, that is, a base color layer is added between the bottom of the groove and the base of the jewelry accessory.

The jewelry body is the same as the gold jewelry body in Example 1, and the groove is also the same as the groove in the gold jewelry body of Example 1. The difference between the colored layer and the colored layer in the jewelry accessories of Example 1 is that the colored layer in this comparative example does not have concave or convex surfaces; it simply fills the groove.

[0147] Comparative Example 2:

[0148] This comparative example provides a gold-inlaid jewelry piece, which includes a jewelry body with a groove formed thereon. A color layer is filled into the groove, and the groove is completely filled. The color layer is made of calcium carbonate.

The test was conducted at temperatures of 15°C-25°C and humidity of 30%-60% RH for 48 hours. The results showed that no corrosion, oxidation, or detachment of the ornament components in Examples 1 to 6 was observed. However, the inlaid ornament components within the grooves of Comparative Examples 1 to 3 showed significant oxidation, noticeable color changes, and a darkening of the luster. Furthermore, some ornament components detached from the grooves, particularly in Comparative Examples 2 and 3.

[0153] The inlaid jewelry in Examples 1 to 6 and Comparative Examples 1 to 3 were examined using a naked-eye method to assess their three-dimensional light reflection.
