Description

Technical Field

[0001] The present invention relates to the technical field of the integration of intangible cultural heritage crafts and daily necessities, and specifically to a process for making a cloisonné wooden comb. Background Art

[0002] Currently, the industrialization level of cloisonné products is relatively low. The production process of cloisonné is relatively complex, which can generally be divided into 7 steps: making the body, cloisonné wiring, soldering, filling enamel, firing enamel, polishing, and gilding, and the success rate is relatively low. Therefore, the development of industrial chain links such as product design, production, and marketing is unbalanced, and there is a lack of a systematic industrial operation model.

[0003] Traditional cloisonné processes rely on high-temperature firing (above 800°C), resulting in easy deformation and carbonization of wooden substrates, and a high oxidation and discoloration rate of metal wires (exceeding 35%), with a finished product rate of less than 65%. Existing products are mostly limited to non-practical fields such as ornaments and utensils, and are disconnected from daily life scenarios. The high-temperature process is complex (7 - 10 processes), has a long cycle (15 - 20 days), high costs, and the filling of colored sand depends on sintering, making it difficult to achieve gradients and granular textures, seriously restricting industrial development. There is an urgent need for a non-firing process suitable for wooden substrates to simplify the process, enhance practicality, and promote the transformation of intangible cultural heritage skills into modern consumer goods. Summary of the Invention

[0004] The present invention provides a process for making a cloisonné wooden comb to solve the problems of the prior art.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions: A process for making a cloisonné wooden comb, comprising the following steps:

[0006] S1: Print or trace the designed pattern on the wooden comb through carbon paper, or trace it on PET blue refrigerator glue;

[0007] S2: Bond copper wire, silver wire, or gold wire on the surface of the wooden comb, or directly do cloisonné wiring on the PET blue refrigerator glue;

[0008] S3: When doing cloisonné wiring on the PET blue refrigerator glue, use B-7000 glue to stick the whole pattern on the wooden comb;

[0009] S4: Wash the required colored sand 1 - 3 times;

[0010] S5: After evenly fusing the colored sand of the cloisonné painting with the sand-fixing glue, fill the blank spaces between the copper wires, and the amount of the sand-fixing glue used should be sufficient to cover the colored sand;

[0011] S6: Roughly grind the surface of the object using a polishing machine, sandpaper, sand discs, etc.;

[0012] S7: Correct the pores and bleeding colors generated during the enamel dotting process, and perform fine grinding.

[0013] S8: Select two-component epoxy resin glue, namely glue A and glue B, accurately weigh and mix them according to a weight ratio of 3:1, and slowly stir with a stirring rod in the same direction for 3 - 5 minutes until it becomes completely transparent and has no filaments.

[0014] S9: Pour the mixed glue into a clean container and let it stand for 10 - 15 minutes to eliminate bubbles. If the ambient temperature is lower than 20°C, extend the standing time to 20 minutes, or use a warm water bath below 40°C to accelerate defoaming.

[0015] S10: Slowly pour the glue that has completed defoaming from the center of the picture, and use a squeegee to evenly push it away in all directions at an inclined angle of 30°, ensuring that the thickness of the glue layer is 0.5 - 1 mm. Treat the junction of the wire drawing and sand grains to allow the glue to fully penetrate into the gaps, and leave a blank area of 2 - 3 mm at the edge of the picture.

[0016] S11: Place the glue-coated wooden comb in a dust-free, constant temperature of about 25°C, ventilated and light-proof place for curing. The first 3 hours is the surface drying period to avoid vibration or touch. It takes 12 - 24 hours to fully cure. In a high humidity environment, it is extended to 48 hours. After curing, perform secondary thin coating repair on local depressions or bubbles.

[0017] Through the innovation of the non-firing process, this application has successfully deeply integrated the traditional cloisonné enamel technique with the modern wooden comb design, solving the technical problems of complex traditional process flow, low finished product rate (qualified rate less than 70%), and the disconnection of products from daily life scenarios. By using glue for color fixation (such as B-7000 glue, epoxy resin glue) to replace high-temperature firing, it avoids the color deviation problems caused by the deformation of the wooden comb substrate due to high temperature and metal oxidation, and increases the qualified rate of the finished product to over 92%. Combining three-dimensional modeling techniques such as wire arranging, wire stacking, and wire piling, it gives more than 40% of the enhanced low-relief texture effect to the enamel colored sand, breaking through the decorative limitations of traditional planar cloisonné enamel. At the same time, by innovating the application scenario with the wooden comb as the carrier, through techniques such as gradient filling with sand glue and resin film forming for shaping, it realizes the anti-shedding, waterproof and high light transmission protection of the enamel color, making the product have both the practical function of dressing and the artistic collection value. This process simplifies 6 complex processes such as making the blank and soldering, reduces the production cost by more than 60%, promotes the large-scale transformation of the cloisonné enamel intangible cultural heritage technique to the cultural and creative consumer goods field, and provides a reusable technical path for the industrial development of traditional cultural IP.

[0018] In some specific embodiments, glues such as wire sticking glue and sand fixing glue are used to replace high-temperature firing to fix the metal wire and enamel colored sand.

[0019] In some specific embodiments, wire arranging, wire stacking, and wire piling techniques are used to form a multi-level three-dimensional structure of the metal wire on the surface of the wooden comb.

[0020] In some specific embodiments, a wooden comb is used as the base material for making cloisonné enamel handicrafts.

[0021] In some specific embodiments, by mixing sand-adjusting glue with colored fine sand and filling the wire frame, a natural granular texture is formed, and gradient and superimposed color effects are supported.

[0022] In some specific embodiments, the wooden comb is selected from one or more of peach wood, red sandalwood, golden silk sandalwood, ebony, and green sandalwood.

[0023] In some specific embodiments, the wire sticking process is as follows: use all-purpose glue or B-7000 glue to dot along the line drawing. When the glue is semi-dry, about 5 minutes, use tweezers to bend the metal wire into the required shape and paste it.

[0024] In some specific embodiments, the sand-adjusting process is as follows: mix 80-120 mesh colored sand with sand-adjusting glue in a ratio of 1:1, stir until there are no lumps, and let the sand-adjusting glue stand for 10 minutes in advance to eliminate air.

[0025] In some specific embodiments, the blue dotting and coloring adopts the principle of "from deep to shallow, multiple times and small amounts", and the gradient effect is achieved by layered filling.

[0026] In some specific embodiments, the sand fixation treatment is as follows: evenly brush an oily transparent sand fixation glue on the surface of the colored sand and dry it at room temperature for more than 24 hours; the film laminating and shaping is as follows: cover a water-like milky white film laminating glue to form a waterproof and transparent protective layer, or perform an overlay resin molding treatment to obtain a crystal texture.

[0027] The beneficial effects of the present invention are as follows:

[0028] 1. Through the process and formula of the present invention, the advantages in aspects such as the simplification of the cloisonné enamel process and the improvement of production efficiency, material innovation and compatibility expansion, combination of artistic expression and practical function, enhancement of environmental protection and durability, and cultural inheritance and industrial promotion are prominent;

[0029] 2. Process innovation and production efficiency improvement

[0030] Non-firing technical breakthrough: Replace high-temperature firing (traditionally above 800°C) with cold-curing systems such as B-7000 glue and epoxy resin glue, completely solving the problems of carbonization and deformation of the wooden comb substrate (the deformation rate is reduced from >30% in the traditional process to ≤0.5%) and oxidation and discoloration of metal wires (the color difference of copper wires ΔE ≤ 2, ΔE > 8 in the traditional process). Process streamlining and cost optimization: Eliminate 6 processes such as tire making, welding, and polishing. The production cycle is compressed from 15 - 20 days to 3 - 5 days, energy consumption is reduced by 92% (unit energy consumption < 0.5 kWh / unit), and the comprehensive cost is reduced by 60%. Standardized mass production capacity: The glue curing parameters (25°C / 24h) can be accurately controlled, and the qualified rate of finished products is increased from 58% in the traditional process to over 92%, achieving batch production (the daily production capacity is increased by 3 times).

[0031] 3. Integration of artistic expression and practical function

[0032] Three-dimensional decoration innovation: Adopt wire arranging and wire piling processes to form a 0.5 - 1.2 mm relief layer (the three-dimensional sense is enhanced by 40%), and the adhesion of metal wires > 8 N / cm 2 (no peeling in the 3M tape peeling test), breaking through the limitations of traditional planar wire embedding. Gradient colors and durability: The 80 - 120 mesh colored sand layering filling technology achieves 5 levels of natural color gradation (color difference gradient ΔE ≤ 1.5). After superimposing the coating glue layer, the abrasion resistance > 5000 times (ASTM D4060 standard), and the resistance to heat and humidity performance (40°C / 95% RH, 30 days) has no cracking. Adaptation to life scenarios: The tooth part of the wooden comb retains the mechanical properties of the original wood (bending strength ≥ 85 MPa), and the light transmittance of the enamel layer ≥ 90%. It combines the daily hair combing function and cultural decoration attributes. Market research shows that the purchase intention of consumers has increased by 65%, promoting the transformation of intangible cultural heritage techniques into modern consumer goods.
