Abstract
Description
Technical Field
[0001] This invention belongs to the field of handicraft preparation, specifically relating to a Tibetan cultural handicraft and its preparation method. Background Technology
[0002] Tibetan cultural handicrafts carry unique religious beliefs and ethnic cultural connotations, and are the core carriers of Tibetan cultural heritage. Common types include architectural models (such as models of the Potala Palace) and personal ornaments (such as prayer beads and bracelets).
[0003] Currently, there are many shortcomings in the production of existing Tibetan cultural handicrafts: First, old prayer flags, as items of special significance in Tibetan culture, are often left idle or disposed of in the traditional way after use, resulting in extremely low resource utilization and failure to fully perpetuate their cultural value; Second, traditional production techniques mostly rely on hand carving, painting, or processing of single materials (pure wood or pure metal), which are cumbersome, inefficient, and difficult to scale up; Third, the integration of core cultural symbols such as prayer flags with the handicraft carrier is not natural enough, often involving surface printing or simple pasting, which is prone to falling off and affects the overall aesthetics and cultural expression.
[0004] Therefore, there is an urgent need for a method to prepare Tibetan cultural handicrafts that can realize the resource utilization of old prayer flags, is simple in process, has excellent finished product performance, and has a high degree of cultural integration. Summary of the Invention
[0005] To address the problems existing in the prior art, the present invention provides a method for preparing Tibetan cultural handicrafts, the method being as follows:
[0006] (1) Mix the broken prayer flags, resin and curing agent to obtain a mixed raw material; (2) Apply adhesive to the substrate surface and attach the mixed raw materials to the substrate surface to obtain a semi-finished product; (3) The semi-finished product is dried and then post-processed to obtain the Tibetan cultural handicraft.
[0007] Preferably, in step (1), the mass ratio of the broken prayer flags, resin and curing agent is 4-6:2-4:1-3.
[0008] Preferably, in step (1), the resin is epoxy resin.
[0009] Preferably, in step (1), the mixing temperature is 30-50°C.
[0010] Preferably, in step (2), the substrate is a metal substrate, a wood substrate, or a resin substrate.
[0011] Preferably, in step (2), the thickness of the adhesive is 1-2 mm.
[0012] Preferably, in step (3), the drying temperature is 30-40℃ and the drying time is 30-60min.
[0013] Preferably, in step (3), the post-processing includes a grinding process, a polishing process, and a coloring process.
[0014] Based on the same technical concept, another aspect of the present invention is to provide a Tibetan cultural handicraft obtained by the above-described preparation method. The Tibetan cultural handicraft can be a model of Mount Kailash, the Potala Palace, etc., or other wearable Tibetan cultural handicrafts, such as prayer beads, bracelets, etc.
[0015] The beneficial effects of this invention are as follows: 1. Balancing the dual value of resources and culture: This invention uses fragments of old prayer flags as the core raw material, realizing the resource recycling and utilization of old prayer flags with religious and cultural significance. It respects Tibetan cultural traditions, avoids resource waste, conforms to the concept of environmental protection, and allows the cultural value of prayer flags to be continuously passed down in handicrafts.
[0016] 2. Excellent finished product performance: The raw material ratio is scientific, and epoxy resin and suitable curing agent are selected to form a stable gel, which ensures the structural strength of the finished product and effectively solves the problems of easy wear and deformation of traditional handicrafts, thus extending the shelf life.
[0017] 3. Excellent cultural integration and aesthetics: Prayer flag fragments are evenly dispersed in the raw materials and naturally blend with the carrier. Post-processing steps (grinding, polishing, and coloring) further enhance the smoothness and gloss of the finished product surface, which not only strengthens the cultural expression effect but also ensures visual and tactile texture.
[0018] 4. Easy to scale up production: The overall process is simple and easy to operate. No complicated equipment is required, which can reduce production costs and enable large-scale production, which is conducive to the promotion and dissemination of Tibetan cultural handicrafts.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0027] Example 1 This embodiment provides a method for preparing Tibetan cultural handicrafts (Buddhist prayer beads), the method being as follows: (1) Prayer flag pretreatment: Select old prayer flags that have been used for 1.5 years. First, use a clean soft brush to remove surface dust, fiber debris and other impurities along the texture of the prayer flag. Then, manually screen and remove parts with more than 10% of the damaged area, mold or stubborn pollution. Finally, use a precision electric cutting machine to cut the qualified prayer flags into uniform fragments with a side length of 2-3 mm. Remove impurities and unqualified parts to ensure the purity of raw materials, uniform fragment size, and avoid uneven dispersion of subsequent mixed raw materials due to uneven fragment size, so as to ensure the consistency of the finished prayer beads.
[0028] (2) Precise proportion of raw materials: Weigh epoxy resin (model E-51), prayer flag fragments and amine curing agent (compatible with E-51 epoxy resin, model T-31) according to the mass ratio of 5:3:2, and control the weighing accuracy within ±0.01g; strictly follow the optimized raw material proportion to ensure that the cross-linking reaction between epoxy resin and curing agent is sufficient, the prayer flag fragments can be stably dispersed, and the structural strength and stability of the finished product are guaranteed.
[0029] (3) Pretreatment of the mixing environment: Place the stainless steel stirring container in a constant temperature water bath and preheat it to 35℃ (within the mixing temperature range of 30-50℃) and keep it warm for 5 minutes; preheat the container in advance to avoid temperature fluctuations during the mixing process from affecting the fusion effect of the raw materials and to ensure the temperature of the mixing system is stable.
[0030] (4) Mixing and stirring: Add the weighed epoxy resin and prayer flag fragments to the preheated mixing container in sequence, start the magnetic stirrer and stir at 60r / min for 5 minutes, then add the curing agent and continue stirring at the same speed for 5 minutes until the mixed raw materials form a uniform, non-solid gel without particles or lumps; the combination of step-by-step feeding and uniform stirring makes the prayer flag fragments evenly dispersed in the epoxy resin, and the curing agent fully penetrates, avoiding incomplete local reaction and forming a stable gel state, laying the foundation for subsequent molding.
[0031] (5) Mold pretreatment: Select a 10mm diameter round silicone mold, wipe the inner wall of the mold with anhydrous ethanol to remove oil and residual impurities. After the ethanol has completely evaporated (about 3 minutes), use a cotton swab to evenly apply a 0.1mm thick layer of release agent (model WD-40) to the inner wall of the mold. Clean the mold to avoid impurities from embedding into the finished product. The release agent can reduce the adhesion between the gel and the mold, making it easier to demold smoothly and preventing the beads from breaking.
[0032] (6) Injection molding: The mixed gel is slowly injected into the pretreated bead mold through a funnel. The injection volume is 95% of the mold volume. During the injection process, the mold is gently shaken 3 times (each shake for 2 seconds) after every 3 injections to remove air bubbles inside the gel. Controlling the injection volume avoids gel overflow. Shaking to remove air can prevent pores from appearing inside the finished product and ensure the compactness of the bead structure.
[0033] (7) Curing treatment: Arrange the molds containing the gel neatly on a room temperature drying rack, keep the ambient temperature at 25°C and humidity at 50%, and let stand for 24 hours to allow the gel to fully cure. Standing at room temperature ensures that the curing reaction proceeds smoothly and avoids excessively high temperature that could lead to excessively fast curing speed and internal stress, thus ensuring the stability of the bead structure and achieving the designed strength.
[0034] (8) Demolding process: After curing, slowly pry open the mold along the mold parting surface, gently remove the bead with tweezers, and place it on a clean foam pad; avoid violent demolding to prevent the edge of the bead from cracking or the surface from scratching, and ensure the integrity of the finished product.
[0035] (9) Graded grinding: i) Coarse grinding: Wrap a cylindrical grinding rod with 400 grit alumina sandpaper and grind the surface of the bead in a circular motion for 5 minutes to remove surface mold marks and burrs; ii) Medium grinding: Replace with 800 grit alumina sandpaper and grind in the same way for 3 minutes to refine the surface texture and eliminate coarse grinding marks; iii) Fine grinding: Replace with 1200 grit alumina sandpaper and grind for 2 minutes to make the surface of the bead initially smooth; graded grinding gradually optimizes the flatness of the bead surface and avoids deep scratches caused by grinding with a single grit of sandpaper, laying the groundwork for the subsequent polishing process.
[0036] (10) Cleaning after polishing: Place the finely polished beads into a beaker containing deionized water and ultrasonically clean for 5 minutes to remove surface polishing dust. Then rinse once with anhydrous ethanol and air dry naturally. Thoroughly remove residual polishing dust to avoid dust affecting the polishing effect and subsequent coloring adhesion.
[0037] (11) Polishing treatment: Place the dried beads into a small roller polishing machine, add 5g polishing wax (model W-50) and 100mL deionized water, and polish at a speed of 1500r / min for 8 minutes. After polishing, take them out, rinse them with clean water, and let them dry. Mechanical polishing improves the smoothness and gloss of the bead surface, and enhances the touch texture and visual effect of the finished product.
[0038] (12) Coloring treatment: Select red weather-resistant water-based pigment with Tibetan cultural characteristics, and use a small spray gun (nozzle diameter 0.3mm) to spray evenly on the surface of the beads. Keep the spraying distance at 15cm and control the spraying thickness at 0.05mm. Water-based pigment is environmentally friendly and odorless. The weather-resistant formula can avoid fading after long-term use. Precise control of spraying parameters ensures uniform color and conforms to Tibetan cultural aesthetics.
[0039] (13) Finished product curing and drying: Place the colored beads in a 30℃ forced-air drying oven and dry for 20 minutes until the pigment is completely cured; gentle drying avoids pigment cracking or falling off, ensures stable color adhesion, and improves the service life of the finished product.
[0040] Example 2 This embodiment provides a method for preparing a Tibetan cultural handicraft (Potala Palace model), the method being as follows: (1) Prayer flag pretreatment: Select old prayer flags that have been used for 1 year. First, gently rinse the surface stains with 30℃ clean water. Then, use a hair dryer (low temperature setting, wind speed setting 3) to dry the prayer flags at a distance of 20cm (about 5 minutes). Manually screen and remove moldy, insect-infested and damaged parts. Use an electric cutting machine to cut qualified prayer flags into fragments with a side length of 1-2 mm. Finally, put the fragments into a 30℃ oven to dry for 10 minutes to remove residual moisture (moisture content controlled at ≤1%). Clean the prayer flag fragments and remove moisture to avoid moisture affecting the gel state and curing effect of the mixed raw materials, and to prevent bubbles or delamination in the finished product.
[0041] (2) Raw material preparation: Weigh epoxy resin (model E-44), prayer flag fragments and amine curing agent (compatible with E-44 epoxy resin, model 650) accurately according to the mass ratio of 5:3:2. After weighing, put them into sealed containers for later use. The accurate ratio ensures the reaction efficiency of epoxy resin and curing agent. Sealed storage avoids moisture absorption or contamination of raw materials and ensures the stability of raw material performance.
[0042] (3) Mixing and stirring: Place the mixing container in a 40℃ constant temperature water bath, first add the weighed epoxy resin, stir and preheat for 2 minutes, then add the prayer flag fragments and curing agent, start the electric stirrer and stir at a speed of 50r / min for 10 minutes until a uniform non-solid gel is formed; the constant temperature water bath ensures that the mixing temperature is stable within the range of 30-50℃, and the uniform stirring makes the prayer flag fragments evenly dispersed in the resin, avoiding local aggregation, and ensuring that the cultural elements on the model surface are evenly distributed.
[0043] (4) Substrate pretreatment: Select a resin Potala Palace model substrate (size 20cm×15cm×8cm). First, use 400-grit sandpaper to lightly sand the surface of the substrate to remove surface dust and smooth layer. Then wipe the surface of the substrate with a cloth dipped in anhydrous ethanol and let it air dry naturally (about 10 minutes). Sanding increases the roughness of the substrate surface and improves the physical adhesion between the adhesive and the substrate. The cleaning step avoids impurities affecting the bonding effect and ensures that the mixed materials and the substrate are firmly bonded.
[0044] (5) Adhesive coating: Select special jewelry glue (model AB-800), pour the glue into a clean plastic tray, and use a stainless steel scraper to evenly apply a 1mm thick layer of adhesive to the pretreated substrate surface. During the coating process, keep the scraper at a 45° angle to the substrate. Control the adhesive thickness to meet the requirements. The special glue has good compatibility with the resin substrate and mixed gel to ensure bonding strength. The 45° angle coating can avoid adhesive accumulation or omission.
[0045] (6) Adhesion and molding: Pour the non-solid gel into a piping bag, spread it evenly point by point through the piping bag and press it onto the base surface coated with adhesive. Control the pressing pressure at 0.5MPa and the pressing time at 2 seconds per point to ensure that the prayer flag fragments are completely covered on the base surface without gaps or accumulation. Pressing makes the gel and adhesive fully contact each other, enhances the adhesion, and evenly distributes the prayer flag fragments to make the cultural elements more natural and improves the overall aesthetics of the model.
[0046] (7) Drying and bonding: Place the bonded semi-finished product into a constant temperature and humidity chamber, set the temperature to 35℃ and the humidity to 55%, and let it stand for 40 minutes to allow the gel to fully bond and cure with the substrate; control the temperature and humidity to avoid drying too quickly, which may cause the gel to crack or not bond firmly, and the constant temperature and humidity environment ensures uniform curing reaction and ensures the stability of the semi-finished product structure.
[0047] (8) Polishing: Take out the dried semi-finished product and use 800 grit sandpaper to lightly polish along the surface texture of the model to remove edge burrs and surface protrusions. After polishing, wipe the surface dust with a clean, dust-free cloth to remove the defects generated during the molding process, so that the model surface is flat and the dust is wiped to avoid affecting the subsequent polishing effect.
[0048] (9) Polishing: Use a small handheld polisher, install a wool polishing wheel, and use polishing paste (model P-30) to polish the model surface at a speed of 1200r / min for 15 minutes. During the polishing process, keep the polishing wheel at a 30° angle to the model surface. The wool polishing wheel and polishing paste work together to gently enhance the gloss of the model surface. Control the speed and angle to avoid damaging the model details and enhance the visual effect and tactile texture.
[0049] (10) Coloring treatment: Select ochre red high temperature resistant oil-based pigment that conforms to the architectural style of Potala Palace. Use a wool brush to apply it evenly to the surface of the model in two coats. After the first coat, let it stand for 10 minutes until the pigment is dry before applying the second coat. The thickness of the coat should be controlled at 0.1 mm. Purpose: Applying the pigment in two coats ensures even coverage and avoids missed areas. The high temperature resistant oil-based pigment has strong adhesion and is not easy to fade, ensuring the long-term preservation of the model.
[0050] (11) Finished product curing: Place the colored model in a 40℃ forced-air drying oven and dry for 30 minutes to allow the pigment to cure completely; Function: Accelerate pigment curing, ensure stable color adhesion, prevent pigment from falling off during use, and improve the overall stability and service life of the finished product.
[0051] Example 3 This embodiment provides a method for preparing Tibetan cultural handicrafts (bracelets), the preparation method being as follows: (1) Raw material preparation: Select old prayer flags that have been used for 2 years, manually screen and remove moldy, damaged and contaminated parts, and use precision cutting equipment to cut qualified prayer flags into uniform fragments with a side length of 1.5-2.5 mm; select epoxy resin (model E-51) as resin raw material, and match it with a suitable amine curing agent (model T-31). Weigh accurately according to the mass ratio of epoxy resin, old prayer flag fragments and curing agent of 5:3:2, and control the weighing accuracy within ±0.01g; (2) Mixing and stirring: Under normal temperature (25-30℃) conditions, first pour the weighed epoxy resin and old prayer flag fragments into a stainless steel mixing container, pre-stir at 50r / min speed for 5 minutes, then add curing agent, and continue to stir at a uniform speed for 5 minutes until the mixed raw materials form a uniform, non-solid gel without particles or lumps. (3) Molding: Select a barrel bead silicone mold with a diameter of 8mm and a length of 12mm. Wipe the inner wall of the mold with anhydrous ethanol to remove oil and impurities. After the ethanol evaporates, slowly inject the non-solid gel into the mold through a funnel. After each injection, gently shake the mold twice to remove internal air bubbles. After the injection is completed, arrange the molds neatly on the drying rack and let them stand for 24 hours to allow the gel to completely solidify. (4) Demolding process: After curing, slowly separate the mold along the mold parting surface, gently remove the barrel bead blank with tweezers, and place it on a clean foam pad to avoid surface scratches; (5) Post-processing: i) Grinding: Grind the barrel bead blank with 400 grit, 800 grit and 1200 grit alumina sandpaper in sequence. Grind with 400 grit sandpaper for 4 minutes to remove mold marks, grind with 800 grit sandpaper for 3 minutes to refine the texture, and grind with 1200 grit sandpaper for 2 minutes to make the surface initially smooth; ii) Polishing: Put the ground barrel bead into a small roller polishing machine, add 3g polishing wax (model W-50) and 80mL deionized water, polish at 1400r / min for 6 minutes, rinse with clean water after polishing and let it air dry naturally; iii) Coloring: Select Tibetan traditional dark blue weather-resistant water-based pigment, use a micro sprayer to evenly spray it on the surface of the barrel bead, control the spray thickness to 0.04mm, and let it stand for 10 minutes after spraying to allow the pigment to dry. (6) Assembly and shaping: Select Tibetan-style raw cotton rope with a diameter of 1.5mm, string the dyed and dried barrel beads into a string of 12 beads, fix the two ends with Tibetan knots, and leave a 1.5cm adjustable knot to obtain the finished bracelet.
