[0014] Figure 1 The present invention is a flow chart of a method for repairing bamboo strip-based lacquer wooden articles. DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] Please refer to Figure 1 A method for repairing bamboo strips lacquer woodware according to the present embodiment comprises the following steps: S1. Damage assessment: Conduct a comprehensive inspection of the bamboo-based lacquerware, determine the scope and degree of damage of the parts to be repaired through dimensional measurement, basic information recording and cultural relic photography, analyze and formulate a repair plan based on the records; When conducting a comprehensive inspection of bamboo lacquerware, we use professional high-precision vernier calipers to measure the dimensions to ensure that the data is accurate to the millimeter level. We record in detail the key dimensions of the lacquerware, such as the length, width, height, and depth and area of ​​the part to be repaired. A comprehensive and accurate damage assessment can provide detailed and reliable data support for the formulation of subsequent repair plans. Before making the printing plate in step S2, the part to be repaired of the bamboo strip lacquerware needs to be cleaned, and after removing oil stains, dust and impurities, the part to be repaired is reinforced with raw lacquer to improve its stability and bearing capacity. Oil stains and dust impurities adhere to the surface of the bamboo strip lacquerware for a long time, and may penetrate into the inside of the bamboo strips, corrode the bamboo fibers, and accelerate the damage of the cultural relics, thereby further protecting the integrity of the cultural relics; When cleaning, use a soft cotton ball dipped in an appropriate amount of alcohol, and use gentle circular motions to carefully wipe the part of the bamboo lacquerware to be repaired. Since alcohol has good solubility and volatility, it can effectively dissolve and remove oil stains, and evaporate quickly to avoid residual liquid from damaging the cultural relics. For hard-to-reach parts such as gaps and corners, you can use a small soft brush, dip it in alcohol and gently brush it to ensure that dust and impurities are completely removed. After cleaning, use a clean soft cloth to dry the part to be repaired. Choose high-quality natural lacquer and apply it evenly to the cleaned part to be repaired with a palm brush. Pay attention to the thickness of the lacquer when applying it, and it is better to be thin and even to avoid accumulation or missed brushing.

[0017] In step S2, before making the printing plate, a piece of bamboo strips with complete and clear patterns is selected according to the shape and size of the part to be repaired. The part with complete and clear patterns is selected as a reference, which can ensure that the texture and shape of the bamboo strips are reproduced as accurately as possible during the printing plate making process. The amount of amorphous silicon dioxide required is designed and calculated according to the part, which can avoid material waste or shortage. The test is carried out again on a similar object of the corresponding size, which provides practical experience and data support for formally making printing plates on cultural relics. Try to choose a part that is far away from the diseased area, with intact bamboo strips and clear patterns. Use a high-precision vernier caliper to accurately measure the length, width, height and curvature of the part, and keep detailed records. Based on the dimensional data of the selected part and the process requirements of printing plate production, calculate the approximate amount of amorphous silicon dioxide required through a mathematical model.

[0018] In step S2, the isolation agent is sodium stearate, the highly active adsorption material is amorphous silica, and a printing plate is made using amorphous silica. The selected part is cleaned and then brushed with sodium stearate. After drying, the bamboo strips are surrounded by oil mud to form an appropriate range and a thin layer of amorphous silica without adding XR-500 curing agent is brushed within the range. A mixture of amorphous silica and XR-500 curing agent prepared in proportion in advance is slowly poured onto the bamboo strips within the range surrounded by the oil mud. After the amorphous silica is cured, the amorphous silica is removed from the bamboo strip lacquerware to obtain a printing plate.

[0019] XR-500 is a new type of organosilicon crosslinking agent. It mainly crosslinks and cures with organic compounds with hydrophilic groups at room temperature or slightly heated and wet conditions to improve the compound's bonding strength, water resistance, solvent resistance, corrosion resistance, hydrolysis resistance, high temperature resistance, weather resistance, toughness, hardness, elasticity, adhesion and other physical properties. This product is an environmentally friendly material that does not contain any formaldehyde and VOC volatiles and is the world's most advanced environmentally friendly material. This product can also coexist with compounds for a long time within a reasonable pH range to achieve a good applicability period for the convenience of customers.

[0020] S2. Printing plate production: brush a layer of isolation agent on a part of a bamboo strip with a complete and clear pattern, which can form an isolation film between the high-activity adsorption material and the bamboo strips, effectively preventing the printing plate from sticking to the bamboo strips after curing. Use oil mud to enclose an appropriate range of the bamboo strips and brush a thin layer of high-activity adsorption material without curing agent in the range. Thinly brushing the high-activity adsorption material without curing agent can fill the tiny pores on the surface of the bamboo strips, reduce the generation of bubbles, make the surface of the printing plate smoother and flatter, and improve the accuracy and quality of printing plate production. Slowly pour the mixture of high-activity adsorption material and curing agent prepared in proportion in advance onto the bamboo strips in the range enclosed by the oil mud. After the high-activity adsorption material is cured, remove the high-activity adsorption material from the bamboo strip lacquerware to obtain the printing plate; Use a soft palm brush, dip it in an appropriate amount of sodium stearate, and brush it along the edge of the part to be repaired from the inside to the outside, evenly and slowly. When brushing, make sure that the sodium stearate fully covers the part to be repaired to avoid missing or accumulation. Then take an appropriate amount of oil mud, knead it in your hands first to make it softer and more plastic. Around the edge of the part to be repaired, fit the oil mud tightly to the surface of the bamboo strips to create a closed enclosure. During the enclosure process, carefully check the sealing between the oil mud and the bamboo strips, press the edge of the oil mud with your fingers to make it tightly combined with the bamboo strips to prevent material leakage. Use a fine brush to thinly brush the high-activity adsorption material without curing agent, and then pour the mixture along the edge of the oil mud enclosure slowly and evenly into the enclosed bamboo strip area. During the pouring process, closely observe the flow of the mixture to ensure that it evenly covers the part to be repaired and no bubbles are generated. If bubbles are found, gently puncture the bubbles with a fine needle.

[0021] S3, coating and drying of raw lacquer: Apply a layer of raw lacquer on the printing surface of the printing plate, dry it naturally after completion, repeat the above operation twice after drying, and extend the drying time for two days after the third application of raw lacquer. Applying raw lacquer multiple times and extending the drying time can make the raw lacquer form a multi-layer structure on the inner surface of the printing plate. After each layer of raw lacquer is dried and solidified, it is closely combined with the next layer to gradually form a solid and continuous lacquer layer. This lacquer layer not only has good wear resistance and corrosion resistance, but also can provide a stable foundation for subsequent processes such as mounting cloth, enhance the bonding force between the printing plate and subsequent added materials, and ensure the quality of the produced lacquer strips; The drying process of raw lacquer is affected by many factors, including temperature, humidity, coating thickness, etc. Prolonging the drying time after the third coating can fully volatilize the water and solvent in the lacquer and completely solidify the raw lacquer. Thoroughly dried raw lacquer can effectively avoid problems such as softening, cracking, and falling off of the lacquer layer caused by insufficient drying, ensure the stability of the lacquer strips during subsequent use and repair, and maximize the quality and effect of the repair work.

[0022] S4, cloth mounting reinforcement: after complete drying, raw lacquer and rice paste are mixed in a ratio of 1:1 to form lacquer paste. Linen of appropriate size is cut. Linen has certain toughness and strength. It is mounted on the surface of raw lacquer and bonded by lacquer paste to form a composite structure with the printing plate. A layer of lacquer paste is brushed on the dried surface of raw lacquer and linen is mounted on it. After natural drying, the filled part of the printing plate after the first mounting is polished. The polishing process can eliminate the unevenness generated during the mounting process and make the surface of the filled part smooth to match the overall texture of the printing plate. The mounting, drying and polishing processes are repeated again. Multiple mounting and polishing processes can fully combine the linen cloth with the lacquer paste and raw lacquer, increase the overall strength and stability of the printing plate, effectively prevent the printing plate from cracking or deforming in subsequent operations, and ensure that the printing plate can remain intact during the lacquer strip production and repair process.

[0023] In step S4, the filling part of the amorphous silica printing plate after mounting and drying is polished with 400-grit sandpaper to ensure that the shape is smooth without protrusions, particles or gaps. When polishing, polish from the center to the edge. Polishing from the center to the edge can ensure that the polishing force is evenly distributed. Starting from the center of the filling part of the printing plate, the restoration personnel can better control the progress and direction of polishing; During the filling process, the accumulation or uneven distribution of materials leads to an uneven surface. Grinding from the center can ensure that all parts of the printing plate are evenly stressed, effectively preventing local over- or under-grinding, and thus ensuring the flatness of the printing plate surface and the accuracy of the shape, so that the repaired printing plate can better fit the original texture and shape of the bamboo strip lacquerware, ensuring that the final lacquer strips can accurately match the part to be repaired, and restore the original appearance of the cultural relics to the greatest extent; the printing plate surface with a smooth shape, no protrusions, no particles, and no gaps is conducive to the smooth progress of subsequent raw lacquer coating, lacquer strip peeling and other processes. When the lacquer strips are peeled off, the uneven surface of the printing plate is easy to damage the lacquer strips. The smooth surface formed by grinding from the center to the edge can reduce these risks, reduce the probability of damage to the lacquer strips during the production and peeling process, and improve the efficiency and quality of the entire repair process; the grinding process can promote a better integration of the filling material and the printing plate itself. The friction generated by grinding from the center to the edge can make the contact interface between the filling material and the amorphous silica printing plate closer, and enhance the bonding between the two. This close combination helps to improve the overall stability of the printing plate. In subsequent repair operations, the printing plate is less likely to have problems such as filling material falling off and delamination, ensuring that the repaired printing plate meets the repair requirements in terms of strength and durability.

[0024] S5. Stripping and repairing of lacquer strips: Soak the removed printing plate in warm water that covers the printing plate. Use the warm water to soften the bonding material between the printing plate and the lacquer strips, so that the bonding force between the printing plate and the lacquer strips is weakened. After two hours, pry with bamboo strips until the printing plate and the lacquer strips are separated. Use a brush to clean the release agent on the surface of the lacquer strips. The clean lacquer strip surface helps to better bond with the bamboo strip lacquerware to be repaired later, ensuring the durability and stability of the repair effect. Soak the printing plate in warm water for a long time, and the viscosity of the adhesive material decreases, which weakens the bonding force between the printing plate and the lacquer strips. At this time, using bamboo pieces to pry can significantly reduce damage to the printing plate and the lacquer strips compared to forcibly separating them in a dry state. The texture of bamboo pieces is relatively soft, and compared with metal tools, it is not easy to scratch or damage the surface of the printing plate and the lacquer strips during the prying process, which maximizes the integrity of both and provides intact materials for subsequent repair work.

[0025] S6. Bamboo strips restoration: Use rice paper to draw the outline of the part to be restored, compare the lacquer strips with the rice paper, remove the excess part of the lacquer strips, grind and adjust the lacquer strips to correspond to the part to be restored, use lacquer paste to stick the lacquer strips to the part to be restored, cover the lacquer strips with plastic wrap and dry them, use rice paper to make a rubbing of the outline of the part to be restored, and provide an accurate template for cutting and adjusting the lacquer strips. By comparing the outline of the lacquer strips with that of rice paper, the excess part of the lacquer strips can be clearly seen and accurately removed to avoid the lacquer strips being too large or too small and not fitting tightly with the part to be restored. Grinding and adjusting the lacquer strips can make them highly consistent with the part to be restored in shape and texture, ensuring the appearance integrity and coordination of the bamboo strip lacquerware after restoration, and restoring the original appearance of the cultural relics to the greatest extent; In step S6, after the plastic wrap is laid on the paint strips, a sandbag is used to press the plastic wrap during the drying process to prevent the paint strips from warping. Pressing the paint strips with sandbags on the plastic wrap can apply uniform and continuous pressure. During the drying process, the paint strips may warp due to shrinkage stress due to evaporation of water. The pressure of the sandbag can effectively offset this stress, making the lacquer strips fit tightly to the part to be repaired, ensuring the firmness and stability of the repair; take out the dried bamboo strips lacquerware cultural relic from the part to be repaired, check the connection between the lacquer strips and the surrounding details, use fine tile ash, raw lacquer, and water in a ratio of 1:1:1 to make lacquer ash, use the lacquer ash to fill the holes and uneven parts, and after drying, use an extremely fine carving knife to carve it until it is consistent with the surrounding details. After the carving is completed, use raw lacquer to adjust the color, test the color on the test color board until the color is consistent, then use a cotton ball to press it on, finally make adaptive adjustments according to the surrounding bamboo strips, use raw lacquer on the test color board until the color is consistent with the surrounding bamboo strips, and then press it to the repair part. This operation is to ensure that the repair area is coordinated and unified in color with the overall cultural relic.

[0026] Working principle of the present invention: The bamboo strips-based lacquer wood restoration method first conducts damage assessment, uses professional tools to accurately measure and record cultural relics information, and provides a basis for the formulation of restoration plans. Before making the printing plate, the part to be repaired is cleaned and reinforced with raw lacquer to prevent impurities from damaging the cultural relics and enhance its stability; a reference area is selected according to the part to be repaired, and the amount of amorphous silica is calculated and tested to ensure the accuracy of the printing plate. When making the printing plate, the oil mud and the high-activity adsorption material without curing agent cooperate with each other to ensure the accuracy and quality of the printing plate production. During the coating and drying process of raw lacquer, multiple coatings and extended drying time are used to form a solid lacquer layer, which provides protection for subsequent processes. Mounting reinforcement uses linen and lacquer paste to form a composite structure, and multiple mounting and polishing enhance the strength of the printing plate, and polishing from the center to the edge ensures the flatness of the printing plate and its fit with the cultural relics. The lacquer strips are peeled off with the help of warm water to soften the bonding material and reduce damage. During the bamboo strips restoration stage, rice paper rubbings provide templates for cutting and adjusting the lacquer strips, plastic wrap and sandbags prevent the lacquer strips from curling, and subsequent filling, carving, and coloring operations make the restored part coordinated with the overall cultural relic in shape, texture, and color, thereby achieving effective restoration of the bamboo strips lacquered wooden objects and restoring their original appearance to the greatest extent possible.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention.
