Description

Technical Field

[0001] The invention relates to the field of enamel, in particular to a method for customizing transparent enamel without K-gold color. Background Art

[0002] Enamelware is an object decorated with enamel, and its basic components are quartz, feldspar, borax and fluoride, which belong to the same silicate substances as ceramic glaze, colored glaze and glass. Enamel is a composite handicraft obtained by applying crushed and ground enamel glaze to the surface of metal products made by metal processing technology, and then drying and firing.

[0003] For example, the invention with the authorization announcement number CN112725798A discloses a process for firing enamel colors on K gold that are not affected by the K gold base color. The document records that "a layer of 0.02mm pure silver foil is pasted on the surface of the glaze material". The pure silver foil recorded in the document is the international pure silver.

[0004] In the international standard, pure silver foil is recognized as the standard of pure silver. 100% silver is soft and cannot be formed during production, making it inconvenient to make into silver ornaments. It is also easy to "oxidize", commonly known as "discoloration". The use of pure silver foil will cause oxidation and discoloration after cooling. The chemical properties of pure silver foil are not stable enough, which affects the presentation of enamel colors, and thus affects the quality of enamel color firing during processing. In addition, the pure silver foil in the document is covered on the glaze. When the firing temperature deviates, the silver foil will disappear, causing the base color K gold to leak out, so that the fired enamel color is affected by the K gold color. Especially when there is a custom pattern in the enamel, it will also affect the custom pattern.

[0005] At present, the above-mentioned method of customizing patterns is generally to pre-position enamel glazes of different colors and then calcine them. For example, a method for preparing hollow transparent enamel jewelry is CN107411254B.

[0006] Therefore, there are the following defects: 1. Once the customized pattern is calcined, it cannot be effectively improved; 2. The leakage of the aforementioned base color K gold will affect the customized pattern, and because the degree and method of leakage are uncontrollable, the degree of impact and the final effect are also uncontrollable. Summary of the invention

[0007] In order to overcome the deficiencies of the prior art, the present invention provides a method for customizing transparent enamel without K gold color. By setting the platinum foil, the performance of the silver foil can be increased to prevent quality problems caused by poor temperature control, reduce resource waste, and improve work efficiency. In addition, creatively, by adding a laser engraving step in the enamel field, some special patterns or texts can be added to the transparent enamel again after the enamel is calcined. It not only overcomes the above two defects, but also can better complete personalized customization and private customization, which has certain significance for the enrichment of enamel culture and the development of enamel technology.

[0008] In order to solve the above technical problems, the present invention provides the following technical solutions: a method for firing enamel color without K gold color, comprising the following steps:

[0009] S1: Platinum foil: Paste platinum foil on the K gold sheet and bake it at 1000℃ to stick it on the K gold sheet, covering the K gold color and presenting the color of platinum foil;

[0010] S2: Paint firing: Apply enamel glaze on the platinum leaf and fire it at 800℃, repeat the glazing and firing until the glaze completely covers the platinum leaf;

[0011] S3: Silver coating: Paste silver foil on the enamel glaze and fire it at 820-830℃ for 24-36 seconds to make the silver foil stick to the platinum foil; (s here means seconds)

[0012] S4: Glazing: Apply enamel glaze on the silver foil and fire it at 800℃, repeat the glaze application and firing until the glaze completely covers the silver foil, then apply an antioxidant glaze protective agent, dry it naturally and then fire it to obtain an enamel intermediate;

[0013] S5: Laser engraving: Use laser to engrave a preset pattern or text on the enamel intermediate product obtained in step S4 to obtain customized enamel.

[0014] As a preferred technical solution of the present invention, the firing time in step S2 is 60 seconds, and the repeated firing time does not exceed 60 seconds.

[0015] As a preferred technical solution of the present invention, the firing temperature in step S3 is 820° C. and the firing time is 30-36 seconds.

[0016] As a preferred technical solution of the present invention, when the firing temperature in step S3 is 820° C., the optimal firing time is 33 s.

[0017] As a preferred technical solution of the present invention, the firing temperature in step S3 is 820-830° C. and the firing time is 30 seconds.

[0018] As a preferred technical solution of the present invention, when the firing time in step S3 is 30 seconds, the optimal firing temperature is 825°C.

[0019] As a preferred technical solution of the present invention, the firing temperature in step S3 is 830° C. and the firing time is 24-30 seconds.

[0020] As a preferred technical solution of the present invention, when the firing temperature in step S3 is 830° C., the optimal firing time is 27 seconds.

[0021] As a preferred technical solution of the present invention, the firing time in step S4 is 60 seconds, and the repeated firing time does not exceed 60 seconds. The temperature of the firing after natural air drying is 900° C. and the time is 8 hours.

[0022] As a preferred technical solution of the present invention, in step S4, the antioxidant glaze protective agent is made of the following raw materials in parts by weight: 20-25 parts of lithium feldspar, 4-6 parts of quartz, 30-35 parts of kaolin, 10-12 parts of zirconium silicate and 12-16 parts of dolomite.

[0023] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0024] 1. Through the setting of platinum foil, covering silver foil on platinum foil can increase the overall performance of silver foil, has an anti-oxidation effect, and can increase the stability of silver foil after cooling, so as to prevent the color of enamel from being affected after firing, so as to prevent the quality after firing and improve the overall success rate of the firing method.

[0025] 2. Due to the fact that platinum foil and silver have the same glossiness, the overall quality can be prevented from being affected by incomplete firing of the silver foil during firing. The silver foil can be fired repeatedly until it is evenly attached to the platinum foil to prevent quality problems caused by poor temperature control, reduce resource waste, and improve work efficiency.

[0026] 3. By coating with platinum foil and silver foil, white transparent enamel glaze and various enamel glazes that need to transition from transparent white to various colors can be fired, which can effectively produce enamel colors that are not affected by K gold color.

[0027] 4. By setting the platinum foil, which has a higher melting point, the platinum foil can be prevented from changing during the subsequent firing process, which can effectively prevent the K gold color from leaking out. In addition, the platinum foil is extremely stable, which can prevent it from bursting and improve safety performance.

[0028] 5. Setting glaze on silver foil can enrich the presentation of enamel color on the glaze, expand the scope of application, provide more choices, and effectively improve the beauty of the product.

[0029] 6. By setting the antioxidant glaze protective agent, the platinum foil and silver foil can be effectively prevented from oxidation when in contact with the air, which is beneficial to the consistency of the surface color of the finished product and can increase the shelf life of the finished product.

[0030] 7. After the enamel is fired, some special patterns or words can be added to the transparent enamel again, which overcomes the defect that the predetermined pattern cannot be effectively improved after the enamel is finished.

[0031] 8. Laser engraving can better customize and personalize enamel products, which is of certain significance to the enrichment of enamel culture and the expansion and development of enamel technology.

[0032] 9. The invention has low cost, easy operation, broad market prospects, and is suitable for large-scale promotion and application. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Figure 1 The present invention is a flow chart of a method for customizing transparent enamel without K-gold color. Implementation

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work all belong to the protection scope of the present invention. The experimental methods in the following embodiments, unless otherwise specified, are conventional methods, and the materials, reagents, etc. used in the following embodiments, unless otherwise specified, can all be obtained from commercial channels. Example

[0035] like Figure 1 As shown, the present invention provides a method for customizing transparent enamel without K gold color, comprising the following steps:

[0036] S1: Platinum foil: Paste platinum foil on the K gold sheet and bake it at 1000℃ to stick it on the K gold sheet, covering the K gold color and presenting the color of platinum foil;

[0037] S2: coating and firing: coating the platinum foil with glaze and firing at 800°C, repeating the glazing and firing until the glaze completely covers the platinum foil;

[0038] S3: Silver coating: Paste silver foil on the glaze and fire at 820℃ for 30-36s to make the silver foil close to the platinum foil;

[0039] S4: Glazing: Apply glaze on the silver foil and fire it at 800℃. Repeat the glaze application and firing until the glaze completely covers the silver foil. Then apply an antioxidant glaze protective agent, let it dry naturally, and then fire it to obtain an enamel intermediate.

[0040] S5: Laser engraving: Use laser to engrave a preset pattern or text on the enamel intermediate product obtained in step S4 to obtain customized enamel.

[0041] Among them, platinum foil has the same luster as silver and is extremely stable. Platinum foil is the same silvery white as silver foil. Covering silver foil on platinum foil can increase the overall performance of silver foil, has an antioxidant effect, and can increase the stability of silver foil after cooling to prevent affecting the color of enamel after firing is completed, so as to prevent affecting the quality after firing and improve the overall success rate of the firing method.

[0042] Since platinum foil and silver have the same glossiness, the overall quality can be prevented from being affected by incomplete firing of the silver foil during firing. The silver foil can be fired repeatedly until it is evenly attached to the platinum foil to prevent quality problems caused by poor temperature control, reduce waste of resources, and improve work efficiency.

[0043] By coating with platinum foil and silver foil, white transparent enamel glaze and various enamel glazes that need to transition from transparent white to various colors can be fired, which can effectively produce enamel colors that are not affected by the color of K gold.

[0044] The present invention creatively adds a laser engraving step in the field of enamel, and can add some special patterns or texts to the transparent enamel after the enamel is calcined. It not only overcomes the above two defects, but also can better complete personalized customization and private customization, which has certain significance for the enrichment of enamel culture and the development of enamel technology.

[0045] As a further implementation of this embodiment, the firing time in step S2 is 60 seconds, and the repeated firing time does not exceed 60 seconds.

[0046] Step S2 is used to fire the glaze on the platinum foil. When the firing time exceeds 60 seconds, the glaze cannot be applied on the platinum foil and will flow on the platinum foil, and may even cause the glaze to slide, resulting in a waste of resources and affecting processing efficiency.

[0047] As a further implementation of this embodiment, the firing time in step S4 is 60 seconds, and the repeated firing time does not exceed 60 seconds. The temperature of the firing after natural air drying is 900° C. and the time is 8 hours.

[0048] Step S4 is used to fire the glaze on the silver foil. When the repeated firing time exceeds 60s, the glaze will not be able to be applied on the silver foil, and will flow on the silver foil, or even cause the glaze to slip, resulting in a waste of resources. More seriously, the glaze will penetrate into the silver foil and merge with the silver foil, seriously affecting the gloss of the silver foil, thereby affecting the success rate after firing is completed and affecting the processing efficiency.

[0049] By setting an antioxidant glaze protective agent, platinum foil and silver foil can be effectively prevented from oxidizing in contact with air, which is beneficial to the consistency of the surface color of the finished product and can increase the shelf life of the finished product. Specifically, lithium feldspar is added because it can improve the whiteness, light transmittance and smoothness of the finished product; quartz is added because it can increase the glaze's ability to corrode water and chemicals, reduce the glaze's expansion coefficient, and increase the glaze's hardness and strength. Kaolin is added because kaolin can improve the glaze's suspension and adhesion. Zirconium silicate is added because zirconium silicate has a high melting point and good chemical stability, which can improve the glaze's hardness and crack resistance. Dolomite is added because it can improve the glaze's hardness and glossiness.

[0050] Example

[0051] like Figure 1 As shown, the present invention provides a method for customizing transparent enamel without K gold color, comprising the following steps:

[0052] S1: Platinum foil: Paste platinum foil on the K gold sheet and bake it at 1000℃ to stick it on the K gold sheet, covering the K gold color and presenting the color of platinum foil;

[0053] S2: coating and firing: applying glaze on the platinum foil and firing at 800°C, repeating the glazing and firing until the glaze completely covers the platinum foil;

[0054] S3: Silver coating: Paste silver foil on the glaze and fire at 820-830℃ for 30s to make the silver foil close to the platinum foil;

[0055] S4: Glazing: Apply glaze on the silver foil and fire it at 800℃. Repeat the glaze application and firing until the glaze completely covers the silver foil. Then apply an antioxidant glaze protective agent, let it dry naturally, and then fire it to obtain an enamel intermediate.

[0056] S5: Laser engraving: using laser to engrave a preset pattern or text into the enamel intermediate product obtained in step S4.

[0057] Example

[0058] like Figure 1 As shown, the present invention provides a method for firing enamel color without K gold color, comprising the following steps:

[0059] S1: Platinum foil: Paste platinum foil on the K gold sheet and bake it at 1000℃ to stick it on the K gold sheet, covering the K gold color and presenting the color of platinum foil;

[0060] S2: coating and firing: coating the platinum foil with glaze and firing at 800°C, repeating the glazing and firing until the glaze completely covers the platinum foil;

[0061] S3: Silver coating: Paste silver foil on the glaze and fire at 830℃ for 24-30s to make the silver foil close to the platinum foil;

[0062] S4: glazing: apply glaze on the silver foil and fire it at 800℃, repeat the glaze application and firing until the glaze completely covers the silver foil, then apply an antioxidant glaze protective agent, dry it naturally and then fire it to obtain.

[0063] S5: Laser engraving: using laser to engrave a preset pattern or text into the enamel intermediate product obtained in step S4.

[0064] Based on Example 1, Example 2 and Example 3, it can be concluded that when the silver foil is attached to the glaze and fired, the firing temperature is between 820-830°C and the firing time is between 24-36s, as shown in Table 1-Table 3:

[0065] Table 1

[0066]

[0067] Table 2

[0068]

[0069] Table 3

[0070]

[0071] It can be seen from Tables 1 to 3 that when the firing temperature is 820°C, the optimal firing time is 33s; when the firing temperature is 830°C, the optimal firing time is 27s; when the firing time is 820-830°C, the optimal firing time is 30s, and the optimal firing temperature in this range is 825°C.

[0072] By setting the platinum foil, when the firing time and firing temperature of the silver foil are not within the optimal firing range, due to the higher melting point of the platinum foil, the silver foil can be fired repeatedly so that the silver foil can be fired in the optimal state, so that the silver foil can be smoothly attached to the platinum foil, and the final result will not be affected by the performance of the silver foil. This ensures that the fired enamel glaze is white and transparent enamel glaze, as well as various enamel glazes that need to transition from transparent white to various colors, and can effectively produce enamel colors that are not affected by the K gold color.

[0073] By setting the platinum foil, which has a higher melting point, the platinum foil can be prevented from changing during the subsequent firing process, which can effectively prevent the K gold color from leaking out. The platinum foil is also extremely stable to prevent cracking. At the same time, setting glaze on the silver foil can enrich the presentation of enamel colors on the glaze, increase the scope of application, and provide more options.

[0074] By setting an antioxidant glaze protective agent, platinum foil and silver foil can be effectively prevented from oxidizing in contact with air, which is beneficial to the consistency of the surface color of the finished product and can increase the shelf life of the finished product.
