It should be understood that the present invention may be embodied in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of a front surface of a noble metal blank 10 according to an embodiment of the present invention, and fig. 2 is a schematic structural diagram of a back surface of the noble metal blank 10 according to an embodiment of the present invention. The preparation method of the enamel precious metal ornament comprises the following steps:
preparing a precious metal blank 10: the noble metal blank 10 is prepared according to the design pattern, and a punching process is performed at a predetermined site of the noble metal blank 10 to obtain the noble metal blank 10 having a plurality of through holes 11.
Specifically, the precious metal green body 10 may be obtained by:
preparing a precious metal blank 10 from a precious metal part (such as a metal sheet) by turning, stamping, milling and the like by using a machining lathe;
drilling holes at preset positions on the blank by using a drilling machine;
and roughly wiping the precious metal blank 10 on a grinding and wiping machine by using 240-400-mesh sand paper until the precious metal blank 10 has no indentation.
The preset points can be end points, folding points and other positions of the design pattern. As an example, the number of the through holes 11 of the precious metal blank 10 is 5, wherein the sites corresponding to the 5 through holes 11 on the front surface of the precious metal blank 10 are respectively labeled as A, B, C, D and E, and the sites corresponding to the back surface of the precious metal blank 10 are respectively labeled as a ', B ', C ', D ' and E '.
Treating the surface of the blank: and (3) carrying out acid pickling treatment on the noble metal blank 10, and coating an adhesive on the surface of the wire distribution track of the noble metal blank 10 after acid pickling.
Wherein, during the acid cleaning treatment, the noble metal blank 10 can be cleaned by adopting a sulfuric acid solution with the mass concentration of 10-15% at the temperature of 30-38 ℃.
Weaving and silk forming: and weaving and tightening the noble metal wires 20 between the through holes 11 in a shuttling way, and pressing the noble metal wires 20 to the surface where the wire distribution tracks coated with the adhesive are positioned so that the front side and the back side of the noble metal blank 10 are both woven with the wire distribution patterns of the noble metal wires 20.
Wherein the aperture area of the through hole 11 may be 2-10 times the cross-sectional area of the noble metal wire 20, so that the noble metal wire 20 can shuttle back and forth in the through hole 11. The size of the aperture of the through hole 11 may be adjusted according to the number of times the noble metal wire 20 is shuttled in the through hole 11.
The noble metal wire 20 may be in the shape of a twisted wire, and the method of preparing the twisted noble metal wire 20 includes the steps of: two strands of 0.12mm noble metal monofilaments are twisted into a twisted shape and then pressed into a synthetic noble metal wire 20 with the cross section thickness of 0.14mm and the width of 0.25mm by a tablet press.
The noble metal wire 20 may also be pre-coated with an adhesive to further improve the reliability of the attachment of the noble metal wire 20 to the wire laying track of the noble metal blank 10.
As an example, taking a as a start point and a stop point, one of the weaving modes is as follows: a → B → B '→ C → D → D' → E → A → A '→ B → C → D' → D → E → E '→ A'. The two points with underlines are wire laying tracks of the noble metal wire 20 on the surface of the noble metal blank 10, for example, a → B is a wire laying track of the noble metal wire 20 between points a and B on the front surface of the noble metal blank 10, and a '→ B' is a wire laying track of the noble metal wire 20 between points a 'and B' on the front surface of the noble metal blank 10. The corresponding points on the front and back surfaces of the noble metal blank 10 are two end points of the through hole 11, such as a and a ', B and B', etc.
After the noble metal wires 20 are woven in a shuttling and weaving manner in each through hole 11, the pattern formed by weaving the noble metal wires 20 on the surface of the noble metal blank 10 is a cloth wire pattern. By the wire tensioning and by pressing the noble metal wire 20, the noble metal wire 20 can be brought into sufficient contact with the glue applied on the surface of the wire laying track in order to better adhere to the surface of the noble metal blank 10.
The adhesive comprises bletilla striata jolt-pulp paste and white latex, and the mass ratio of the bletilla striata jolt-pulp paste to the white latex is 7: 10, the proportion of the adhesive with the mass ratio is greatly different from that of the existing common adhesive, so that the bonding effect of the adhesive and the noble metal wire 20 can be improved.
Sintering blank hole enamel: and filling the through hole 11 with low-temperature glaze containing sodium polyacrylate until the filled low-temperature glaze is flush with the noble metal wire 20 in the axial direction of the through hole 11, and performing primary firing.
The first firing is carried out for 8-10min at the firing temperature of 260-.
The sodium polyacrylate can play a thickening role in the low-temperature glaze so as to prevent the low-temperature glaze from migrating in the first firing process, and the noble metal wire 20 is not easy to separate from the low-temperature glaze after the firing process is finished.
The mass of the sodium polyacrylate accounts for 0.21-0.36% of the mass of the low-temperature glaze, and the viscosity of the sodium polyacrylate is 10000-15000 mPa.s. Within the numerical range, the sodium polyacrylate has better thickening effect on low-temperature glaze.
The colorant comprises one or more of chromium oxide, cobalt oxide, zirconium oxide, phthalocyanine blue, manganese oxide, benzidine yellow G and permanent orange G.
The preparation method of the low-temperature glaze comprises the following steps:
taking the following raw materials in parts by weight: 40-50 parts of albite; 20-30 parts of tremolite; 5-15 parts of borax; 10-30 parts of volcanic rock and 10-20 parts of talcum; 0.5-4 parts of strontium carbonate; 10-15 parts of magnesium oxide; 5-15 parts of zinc oxide; 2-5 parts of a coloring agent;
mixing albite, tremolite, borax, volcanic rock, talc, strontium carbonate, magnesium oxide and zinc oxide, pulverizing, and sieving. The mesh number of the sieve can be 60-100 meshes.
Calcining at 1000-1100 deg.C for 5-8 hr;
cooling the calcined mixture to 600-700 ℃, adding the colorant, heating to 800-900 ℃, and continuing for 3-5 hours;
after heating, naturally cooling to below 100 ℃, and adding water accounting for 35-50% of the total mass of the raw materials for grinding. After grinding, the low-temperature glaze can be obtained.
And (3) bluing: filling low-temperature glaze into the cloth wire pattern, wherein the filling height of the low-temperature glaze is lower than that of the noble metal wire 20 of the cloth wire pattern, and performing secondary firing; and filling the high-temperature glaze into the cloth wire pattern until the filling height of the high-temperature glaze is flush with the height of the noble metal wire 20 in the cloth wire pattern, and carrying out third firing, wherein the firing temperature of the third firing is higher than that of the second firing.
The second firing is carried out for 5-7min in the environment of 260-300 ℃. The third firing is carried out for 1-1.5min in an environment of 760-810 ℃.
Because the sodium polyacrylate is added into the low-temperature glaze filled in the through hole 11, the first firing can be carried out at a lower temperature, the glaze in the through hole 11 and the glaze on the front and back sides are mixed and stringed when the glaze is bluing, and in addition, because the cloth silk pattern filled in and the low-temperature glaze filled in the through hole 11 are the same, the enamel finally fired into the enamel precious metal ornament has good color consistency and does not have the problem of inconsistent color.
Because the filled low-temperature glaze is lower than the height of the wire distribution pattern before the second firing, and the filling height of the filled high-temperature glaze is flush with the height of the noble metal wire 20 in the wire distribution pattern before the third firing, the enamel noble metal ornament after the third firing has an inner layer formed by low-temperature firing and an outer layer formed by high-temperature firing. Wherein, the high-temperature glaze can be prepared conventionally. The outer layer of the enamel precious metal ornament fired at high temperature is a high-transparency layer and has higher hardness, the inner layer has richer bright colors and is matched with the transparent and high-hardness outer layer fired at high temperature to present, and the high-hardness outer layer can play a role in preventing scratches when the enamel precious metal ornament is worn and used.
And (6) polishing. During polishing, agate can be used for dipping clean water to repeatedly scrape, press and polish the surface of the enamel precious metal ornament after the third firing, and the places where the precious metal wires 20 in the cloth wire pattern are exposed are waxed and polished, so that the brightness of the enamel on the surface of the finished product is improved.
In some preferred modes, the peripheral edges of the front surface and the back surface of the precious metal blank 10 are provided with flanges 12, and the through holes 11 are positioned in the area enclosed by the flanges 12, so that after the weaving and silking are finished, a spot glaze firing area is formed between the peripheral surface of the silk distribution pattern and the flanges 12, so that when the spot blue step is carried out, the spot glaze firing area can be filled with glaze for firing, and the enamel area on the enamel precious metal ornament is increased.
In the weaving and filament forming step, when there is an intersection position of the noble metal wire 20 (F, G, H, I, J in fig. 1 is a position point of the intersection position of the noble metal wire 20 existing on the front surface of the noble metal blank 10, respectively, and F ', G ', H ', I ', J ' in fig. 2 is a position point of the intersection position of the noble metal wire 20 existing on the front surface of the noble metal blank 10), a groove is provided on the noble metal blank 10 at a position corresponding to the intersection position.
Because the surface of the noble metal wire 20 of the wire distribution pattern can form an enamel surface after the filling glaze is fired, if the surface of the noble metal wire 20 of the wire distribution pattern is uneven, the flatness of the enamel surface of the finished enamel noble metal ornament can be influenced. Therefore, the protruding part of the intersecting position of the noble metal wire 20 is accommodated in the groove, so that the intersecting part of the noble metal wire 20 can be pressed into the groove when the noble metal wire is woven in a shuttling mode, the flatness of the surface of the wire cloth pattern formed by shuttling of the noble metal wire 20 is guaranteed, and the flatness of the enamel surface of the enamel noble metal ornament is guaranteed.
