Description

Technical Field

[0001] The invention relates to a preparation material and a manufacturing method thereof, and in particular to a preparation material and a manufacturing method thereof for quantitative production of colored sculpture handicrafts. Background Art

[0002] Colored sculpture is the abbreviation of "color sculpture". It is a plastic art that combines modeling and painting, and is a high degree of unity of form and color. Taking Tianjin Clay Figure Zhang's colored sculpture as an example, its quantitative production is divided into six processes: ① Shaping the prototype--② Making the plaster mold--③ Making the clay mold--④ Clay mold trimming--⑤ Clay mold drying--⑥ Clay mold painting. The material used in the ③ clay mold making stage of traditional clay colored sculpture is "clay", and the clay mold is painted and colored to complete the product. However, the traditional material "clay" has many disadvantages:

[0003] 1. Raw materials are difficult to obtain and often need to be dug from a specific depth in the soil. There are many impurities and the initial processing is cumbersome.

[0004] 2. Clay collected from natural soil poses health and safety risks.

[0005] 3. During the drying process of handicrafts, the shrinkage is uneven and the stability is poor.

[0006] 4. It is not suitable for long-term storage. In the later stage, it will still crack and powder due to the influence of weather and humidity.

[0007] 5. It is difficult to accurately control unified quality standards during the process of mass production of products.

[0008] 6. The process of quantitative production of products consumes a lot of manpower.

[0009] 7. If firing is involved, it is quite difficult, and cracks and other defects will occur after firing, resulting in a low yield.

[0010] In summary, the "clay" used in traditional colored sculpture artworks has problems such as difficulty in obtaining, complicated processes, high labor costs, and has obvious limitations in product quantification.

[0011] Taking resin materials as an example, there are the following disadvantages:

[0012] Deformation: Resin crafts are prone to deformation during the production process. This is mainly because the resin solidification shrinkage produces uneven internal stress inside the product, causing the product to bend and deform.

[0013] Cracking: Resin crafts may crack after demoulding, which is usually caused by slow post-curing of the resin or improper demoulding.

[0014] Delamination: During the production process, resin crafts may delaminate. This is usually caused by improper operation or uneven mixing of materials. Solving the delamination problem requires ensuring that the materials are fully mixed and paying attention to details during the operation.

[0015] The potential hazards of resin crafts to the human body include:

[0016] Skin irritation: Long-term contact with resin may cause skin irritation, causing contact dermatitis, local rash and itching and other symptoms.

[0017] Effects on the liver and kidneys: The pungent smell emitted by the resin may affect the liver and kidney functions of the human body, and long-term inhalation may cause liver and kidney discomfort.

[0018] Impact on the hematopoietic system: Resin is a chemical substance. Long-term exposure may affect the hematopoietic system and may cause anemia in severe cases.

[0019] Respiratory irritation: Low-quality resins may contain harmful chemicals, and long-term exposure may cause health problems such as headaches, eye and respiratory irritation.

[0020] It can be seen that traditional clay sculpture materials have the following limitations: Traditional clay sculptures mainly use natural clay excavated from the ground as raw materials, and the acquisition and processing process of this material is primitive and time-consuming. First, a large amount of manpower is required to remove impurities in the clay, such as grass roots and tree roots, which is a time-consuming and laborious step. Secondly, the traditional drying method relies on natural drying, which is greatly affected by the weather and cannot guarantee the continuity and efficiency of production, which in turn affects the stability of the entire production schedule.

[0021] Modern production needs: With the development of the times, the market demand for handicrafts is increasing, and traditional handmade methods are difficult to meet the needs of large-scale production and product quantification. In addition, handicrafts made of traditional clay materials are not hard enough, easy to deform and fragile, which is not conducive to long-distance transportation and long-term preservation. At the same time, there are also problems such as hygiene and environmental protection in the production process, which limit the application and development of traditional clay materials in the contemporary era. Summary of the invention

[0022] In order to solve the deficiencies of the above-mentioned technologies, the present invention provides a preparation material and a production method thereof for the mass production of colored sculpture handicrafts, so as to solve the problems existing in the mass production of clay materials used in traditional colored sculpture handicrafts.

[0023] In order to solve the above technical problems, the technical solution adopted by the present invention is: a preparation material for the quantitative production of colored sculpture handicrafts, comprising the following raw materials in parts by weight: 25-35 parts of red gypsum powder, 5-15 parts of volcanic stone particles, 3-13 parts of red jade particles, 1-3 parts of natural hemp fiber and 45-55 parts of water.

[0024] Preferably, the following raw materials are included in parts by weight: 30 parts of red gypsum powder, 10 parts of volcanic stone particles, 8 parts of red jade particles, 2 parts of natural hemp fiber and 50 parts of water.

[0025] Extra-hard and high-strength red gypsum powder: a basic component that does not deform during the curing process, can use a more precise silicone mold, does not require secondary finishing after demoulding, and has low labor costs.

[0026] The advantages of volcanic rock particles are as follows:

[0027] Rich touch: The presence of volcanic stone particles will make the surface of the handicraft have a certain degree of roughness and granularity. When people touch it, they can feel a unique touch different from the smooth plaster surface, which adds a different charm to the handicraft.

[0028] Enhanced firmness: Volcanic stone itself has high strength and hardness. Adding it to the cast gypsum is equivalent to adding a reinforcing phase to the gypsum matrix, which can improve the overall strength and hardness of the colored sculptures, making them more durable and not easy to be damaged or cracked, which is beneficial to extend the service life of the crafts.

[0029] Reduce weight: Volcanic stone is a porous material with relatively low density. Adding an appropriate amount of volcanic stone particles to gypsum can reduce the overall weight of the colored sculptures to a certain extent, making them easier to handle, transport and display, while also reducing transportation costs and support requirements during display.

[0030] Increase thermal insulation: volcanic stone has good thermal insulation performance. After adding it to the cast plaster, it can make the colored sculptures have a certain thermal insulation effect. This is very beneficial for some colored sculptures that are sensitive to temperature. For example, when displayed or stored in a high temperature environment, it can reduce the impact of the external temperature on the crafts and maintain their stability.

[0031] Enriching cultural connotations: Volcanic rocks are products of nature and are closely related to the earth's geological activities and natural phenomena such as volcanic eruptions. Using volcanic rock particles in colored sculptures can give the crafts a unique geological and cultural connotation, allowing people to feel the magic and power of nature while appreciating the crafts, increasing the cultural value and artistic heritage of the crafts.

[0032] Environmental sustainability: volcanic stone is a natural material with a wide range of sources and is renewable. Using volcanic stone particles as an additive for colored sculptures meets the requirements of modern society for environmental protection and sustainable development, helps reduce dependence on traditional non-renewable materials and reduces the impact on the environment.

[0033] Akadama granules have the following advantages:

[0034] Unique appearance: Akadama is usually dark red or brown, with fine particles. When added to the cast plaster, it can bring unique color and texture to the colored sculptures, enriching the visual level of the works.

[0035] Natural style: The natural color and granularity of Akadama can give handicrafts a natural and simple style, making them more artistic and ornamental.

[0036] Enhanced stability: Akadama has certain viscosity and water retention, which can better combine with gypsum, enhance the overall stability of colored sculptures, and reduce the risk of cracking and deformation.

[0037] Regulating humidity: Akadama can absorb and release a certain amount of moisture, which helps to regulate the humidity around the colored sculptures and avoid damage to the works due to excessive dryness or humidity.

[0038] Natural materials: Akadama is a natural soil particle that is non-toxic and harmless and meets environmental protection requirements. Using Akadama as an additive material helps reduce dependence on chemical synthetic materials and reduce the impact on the environment.

[0039] Akadama can be obtained in a sustainable way, such as from specific mining areas or natural environments, ensuring a sustainable supply of material to meet long-term production needs.

[0040] Natural hemp fiber: Adding hemp fiber to the cast plaster in the production of colored sculptures has the following main benefits: Hemp fiber can significantly enhance the connection firmness of colored sculptures. Due to its own characteristics, it plays a role similar to "reinforcement ribs" in plaster, greatly improving the toughness of colored sculptures, making the crafts less likely to break or be damaged, thereby effectively improving the quality and durability of colored sculptures.

[0041] A handicraft made from materials prepared for the quantitative production of colored sculpture handicrafts.

[0042] A method for making a handicraft, the method comprising the following steps:

[0043] S1, Prototype creation;

[0044] S2, making a silicone mold;

[0045] S3, filling raw materials;

[0046] S4, embryo removal and trimming;

[0047] S5, embryos are dried in the sun;

[0048] S6, embryo painting.

[0049] Preferably, the filling of the raw materials comprises the following steps:

[0050] Step 1: Raw material preparation: including procurement, inspection and storage;

[0051] Step 2: Premixing of raw materials: Mix red gypsum powder, volcanic stone particles and red jade particles evenly according to proportion;

[0052] Step 3: Fiber dispersion: Cut the natural hemp fiber into 1-2 cm and evenly sprinkle it into the above premix;

[0053] Step 4: Add water to mix: slowly add water in an amount equal to the current mixture, stirring while adding until a uniform and moist mixture is formed;

[0054] Step 5: Vacuum treatment: subject the mixed raw materials to vacuum treatment;

[0055] Step 6: Injection molding: Inject the vacuum-treated raw materials into the mold.

[0056] The new type of perfusion material introduced by the present invention is safe and hygienic, and has great advantages in quantitative production, as follows:

[0057] Improve the hardness and fineness of product shape: After formula design, it has extremely high fluidity, suitable for mold production and can easily meet the needs of various complex shapes. It allows more delicate modeling, allowing designers to turn more creativity into reality, while also reducing the difficulty of operation for craftsmen.

[0058] Promote large-scale production: This material can significantly improve production efficiency, reduce costs, and enable companies to quickly respond to changes in market demand.

[0059] Ensure product quality consistency: Stable and controllable ingredients ensure that the quality and performance of each batch of products are basically consistent. This is of great significance for building brand reputation and expanding market share. In addition, it also helps to reduce scrap rate and further improve economic benefits.

[0060] Enhanced environmental friendliness: Environmentally friendly formula, free of harmful chemicals, and easy to recycle. Minimizes the impact on the natural environment throughout the life cycle, in line with the concept of sustainable development.

[0061] In short, the research and development and application of the preparation material of the present invention not only make up for the shortcomings of the existing technology, but also bring revolutionary changes to the colored sculpture handicraft industry. It is not only a new material choice, but also an important force to promote the development of the colored sculpture handicraft industry in a greener and more efficient direction.

[0066] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0067] A preparation material for the quantitative production of colored sculpture handicrafts, which adopts a mold injection production method.

[0068] The raw materials include: extra-hard and high-strength red gypsum powder, volcanic stone particles, red jade particles, natural hemp fiber and water. The specific ratio is as follows:

[0069] Extra-hard and high-strength red gypsum powder accounts for 30%: it provides basic structural strength and distinctive color characteristics.

[0070] Volcanic stone particles account for 10%: increase the wear resistance and texture of the material, while bringing a unique natural texture effect.

[0071] Akadama particles account for 8%: further enhancing hardness and stability, giving the work a jade-like appearance.

[0072] Natural hemp fiber accounts for 2%: significantly improves toughness, making the finished product more durable and less prone to cracking.

[0073] Water accounts for 50%: as a blending agent, it ensures that all components are evenly mixed and promotes the molding of materials.

[0074] Optimization of raw material acquisition and processing: In view of the difficulty in obtaining "clay" raw materials, the high amount of impurities, and the cumbersome processing, the present invention adopts a new synthetic material, which not only reduces the difficulty of collecting raw materials, but also significantly reduces the pre-processing procedures, making it easier for later painting and coloring, making the entire production process more efficient and convenient. At the same time, the new material has a higher purity, effectively avoiding health and safety hazards, and providing a safer creative environment for artists and producers.

[0075] Compared with traditional colored sculpture materials, each material in the formula of the present invention has a clear and convenient acquisition channel and can be purchased through formal channels. However, the yellow clay used in the traditional colored sculptures of Tianjin Clay Figure Zhang has unclear acquisition channels and needs to be dug from the ground. Not only is there a problem in the procedure, but it may also face challenges in legality and sustainability. The materials in the formula of the present invention do not have obstacles in obtaining raw materials, and can ensure stable production and sustainable development.

[0076] The clay used in traditional clay sculptures requires complicated preliminary processes before it can be used as clay sculpture materials: it needs to be dug from the ground manually, and a lot of manpower is needed to remove impurities such as grass roots and tree roots from the clay, and then it is naturally dried in the sun (a step that is greatly affected by the weather, and the continuity and efficiency of production cannot be guaranteed, which in turn affects the stability of the entire production schedule). However, this application does not require such complicated preliminary processing, and only needs to blend the raw materials according to the formula, thus reducing the preliminary processes.

[0077] Innovation in stability and preservation: In order to solve the problems of uneven shrinkage, poor stability and easy cracking and powdering during long-term storage during the drying process, the new material can maintain high uniformity during the drying and curing process, with almost no shrinkage and deformation, ensuring the accurate reproduction of the shape of the handicraft. In addition, the material has excellent crack resistance and weather resistance, and can maintain good appearance and structural integrity even in extreme weather or after long-term storage, greatly extending the service life of the handicraft.

[0078] There are several reasons why gypsum is uniform and does not deform during the curing process:

[0079] 1. Material properties

[0080] 1. Chemical stability: The main component of gypsum is calcium sulfate (CaSO4), and the chemical reaction during the solidification process is relatively stable. Calcium sulfate dihydrate (CaSO4·2H2O) dehydrates to form calcium sulfate hemihydrate (CaSO4·0.5H2O), which then absorbs water to re-form calcium sulfate dihydrate crystals. In this process, the growth of crystals is relatively orderly, and there will be no drastic volume changes or uneven chemical reactions, which helps to maintain the uniformity and stability of the solidification process.

[0081] 2. Particle uniformity: Commercially produced gypsum is usually finely processed and has a relatively uniform particle size. When mixed with water, it can be dispersed more evenly, so that the starting conditions of the curing reaction are similar in all parts. Uniform particles help uniform penetration of water and uniform reaction, avoiding local too fast or too slow curing, thereby ensuring the uniformity of the curing process.

[0082] 2. Curing Mechanism

[0083] 1. Crystallization process: Gypsum solidification is mainly through the rehydration of calcium sulfate hemihydrate to form calcium sulfate dihydrate crystals. During the growth process, the crystals will be arranged and stacked in a relatively regular manner. This orderly crystallization process makes the growth rate of the material in all directions more consistent, thereby reducing the possibility of uneven deformation. The bonding force between the crystals is relatively uniform, and they can jointly withstand external stress and maintain overall stability.

[0084] 2. Self-restraint: As the solidification progresses, the gypsum gradually forms a whole, and the internal crystal structure restrains each other. This self-restraint can limit local deformation and uneven shrinkage. Even if some small stress is generated during the solidification process, it will be dispersed and balanced through the interaction between the crystals, thus avoiding obvious deformation.

[0085] 3. Construction Condition Control

[0086] 1. Water-cement ratio control: During the construction process, it is very important to reasonably control the ratio of gypsum to water (water-cement ratio). An appropriate water-cement ratio can ensure that the gypsum slurry has good fluidity and plasticity, and also ensure the uniformity of the curing process. If the water-cement ratio is too high, the slurry may be too thin, the strength after curing is low and uneven deformation is prone to occur; if the water-cement ratio is too low, the slurry has poor fluidity, which may lead to uneven construction and affect the curing quality. Professionals will accurately control the water-cement ratio to obtain the best curing effect.

[0087] 2. Mixing uniformity: In the process of mixing gypsum and water, sufficient mixing is the key to ensure uniform curing. Mixing can make the gypsum particles fully contact with water and evenly distribute in the slurry. Uniform mixing can avoid the occurrence of insufficiently hydrated areas or particle aggregation, thereby ensuring the consistency of the curing process. Using appropriate mixing equipment and methods, stirring at a certain time and speed, can improve the uniformity of mixing.

[0088] Precise control and quality improvement of quantitative production: The new material of the present invention shows great advantages in quantitative production, so that each batch of handicrafts produced can meet highly consistent quality standards. This not only reduces human errors in the production process, but also improves production efficiency, providing a solid foundation for large-scale and standardized production. At the same time, the use of new materials simplifies the production process, reduces the dependence on highly skilled craftsmen, and makes the production of the molding process of colored sculpture handicrafts more popular and popular.

[0089] 1. Upgraded molds and improved craftsmanship:

[0090] In the quantitative production process, traditional yellow glue uses gypsum molds, while this application uses silicone molds.

[0091] Accuracy of handicraft modeling: Gypsum may shrink to a certain extent during the solidification process, which will affect the dimensional accuracy of the mold. In addition, the processing accuracy of gypsum molds is relatively low, and the color sculpture craft products produced have large dimensional deviations, poor surface flatness and finish; silicone has a smaller shrinkage rate during the curing process, which can better maintain the dimensional stability of the mold, thereby ensuring the dimensional accuracy of the product. It is more delicate and the crafts produced are more refined. Through sophisticated processing techniques, such as CNC processing, high-precision molds can be produced, which can meet the production needs with high requirements for product dimensional accuracy and surface quality.

[0092] The production process of gypsum molds requires making a prototype first, and then remaking the mold. The process is relatively cumbersome, and the solidification time of gypsum is long, and it takes a while to proceed to the next step. The entire production cycle is long and the production efficiency is low. The production of silicone molds is relatively simple. It can be made by pouring, brushing, etc. It has a fast curing speed, which can greatly shorten the production cycle and improve production efficiency. Moreover, silicone molds can be made and modified on-site as needed, which is highly flexible.

[0093] The adhesion between the gypsum mold and the product is strong, and the product is likely to stick to the mold during demoulding, making demoulding difficult and even damaging the product. Especially for some products with complex shapes, deep cavities or undercut structures, the demoulding problem is more prominent. Silicone has good demoulding properties, its surface is smooth, and the adhesion between it and the product is small, making demoulding easy. Even for products with complex shapes, it can be demoulded smoothly without causing damage to the product, greatly improving the production efficiency of handicrafts and the qualified rate of products.

[0094] 2. Reduce labor costs and unify product quality:

[0095] In the quantitative production stage, traditional clay sculptures require manually pressing yellow glue into plaster molds to cast rough clay blanks. This rough blank requires a lot of manpower for fine-tuning, and the quality of manual trimming is difficult to maintain uniformity. The process is relatively primitive, with high costs and low efficiency. The present application only requires pouring silicone molds, demolding, and simple manual trimming.

[0096] 3. Shorten the production cycle: The production cycle of each colored sculpture made of traditional yellow clay is about 2 days, while the production cycle of each colored sculpture made by the present application only takes about 4 hours (2 hours for pouring and 2 hours for finishing).

[0097] The production process is:

[0098] 1. Raw material preparation stage: Collect and screen natural raw materials to ensure that the purity and particle size meet the standards.

[0099] 2. Pre-mixing stage: Mix the red gypsum powder, volcanic stone particles and red jade particles evenly in proportion.

[0100] 3. Fiber dispersion: Cut the natural hemp fiber to a suitable length (1-2 cm) and sprinkle it evenly into the premix.

[0101] 4. Add water to mix: Slowly add water according to the proportion, stirring while adding until a uniform moist mixture is formed.

[0102] 5. Vacuum treatment: Vacuum the mixed materials.

[0103] 6. Injection molding: Inject the mixed material into the mold.

[0104] 7. Drying and curing: Natural curing to ensure complete hardening.

[0105] 8. Surface treatment (optional): polishing, coloring or other decorative treatments to enhance aesthetics.

[0106] The quantitative production of the preparation materials of this application is divided into six processes: ① shaping the prototype--② making the silicone mold--③ pouring the material--④ material trimming--⑤ material drying--⑥ material painting.

[0107] Example

[0108] 1. Artists create prototypes of colored sculptures (this is not within the scope of production, so no detailed description is given).

[0109] 2. Make the silicone mold of the product: Figure 2 As shown;

[0110] 3.Pouring materials:

[0111] Raw material preparation: including procurement, inspection and storage.

[0112] Raw material standards: Materials prepared according to the formula: extra-hard and high-strength red gypsum powder (30%), volcanic stone particles (10%), red jade particles (8%), natural hemp fiber (2%), and water (50%).

[0113] Premixing: Mix red gypsum powder, volcanic stone particles and red jade particles in proportion;

[0114] Fiber dispersion: Cut the natural hemp fiber into 1-2 cm and sprinkle it evenly into the premix. It takes about 10 minutes to complete.

[0115] Add water to mix: Slowly add a certain amount of water (1:1 with the current mixture), stirring while adding, until a uniform moist mixture is formed, which takes about 15 minutes.

[0116] Vacuum treatment: Vacuum the mixed materials.

[0117] Pouring: Pouring the mixed material into the mold.

[0118] Embryo out of the mold, simple trimming, such as Figure 3 As shown. Entering the molding stage, this stage takes about 2 hours depending on the complexity of the product.

[0119] Embryo drying: After forming, it is immediately transferred to the drying area. The drying time depends on the size and thickness of the product, generally within 24 to 48 hours.

[0120] Embryo painting: After drying, quality inspection and necessary surface treatment are carried out. The material embryo is completed and ready for painting, such as Figure 4 shown.

[0121] This application changes the clay modeling process of clay sculptures into casting materials, and its quantitative production is divided into six processes to improve and increase the material, quality and production capacity of the steps of ③ clay modeling--④ clay model trimming--⑤ clay model drying. The reduction of processes first makes the material itself simpler to use, and secondly reduces the manpower required.

[0122] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the scope of the technical solution of the present invention also belong to the protection scope of the present invention.
