AI Technical Summary
In existing lacquer-jade fusion techniques, the connection strength between the jade and the lacquer body is insufficient, causing the product to easily fall off. This makes it unsuitable for mass production of large-sized handicrafts and lacks a reliable connection structure with multi-point riveting reinforcement.
Ramie rivets are used to mechanically embed and fix the jade components and the pre-drilled holes in the body. A sealant adhesive layer is formed by combining lacquer, glutinous rice flour and tile ash. The number of pre-drilled holes is increased according to the size of the body and they are distributed in an array to form a multi-point riveting connection.
It improves the tensile and shear strength and long-term reliability of lacquer-jade fusion crafts, supports the mass production of large-sized objects and various body types, and achieves the firmness and durability of structural connections.

Technical Field
[0001] This invention relates to the field of lacquer and jade fusion technology, specifically a lacquer and jade fusion craftwork inlay and reinforcement process. Background Technology
[0002] Currently, most products and images of lacquerware combined with jade seen on the market and online use jade as the base, applying lacquer to the surface to create lacquer-jade fusion products. This type of jade-based craftsmanship is complex, time-consuming, and costly, and is constrained by the price and characteristics of raw materials, making mass production difficult and unsuitable for large-sized products. Furthermore, existing lacquer-jade fusion techniques often use adhesive bonding or base wrapping to connect the jade and lacquerware, resulting in insufficient bonding strength between the two materials, easy detachment during later use, and unstable quality issues. This makes it unsuitable for various jade shapes, and there is no known technical solution using fabric rivets as independent connectors, mechanically embedding them through pre-drilled holes in the jade components and base. Especially when the base size increases, there is a lack of reliable mechanical connection structures that can increase the number of openings and use multi-point riveting reinforcement to accommodate the increased base size, resulting in compromised strength and durability of large-sized lacquer-jade fusion products.
[0003] Therefore, we have made improvements to this and proposed a lacquer-jade fusion craftsmanship inlay and riveting reinforcement process. Summary of the Invention
[0004] The purpose of this invention is to provide a riveting and reinforcement process for lacquer-jade fusion crafts to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution, comprising the following steps: Step 1: Based on the size of the base and the shape of the jade components, make multiple pre-drilled holes on the bottom of the base and on the jade components. The larger the base size, the more holes should be made. Step 2: Prepare ramie cloth rivets. The ramie cloth rivets are made by coating coarse ramie cloth with a mixture of lacquer and glutinous rice flour to form small round pieces, and then wrapping the small round pieces with long strips of ramie cloth. Step 3: After applying paint putty to the ramie cloth rivets, pass them through the reserved holes in the jade component and the reserved holes in the base body in sequence for riveting and fixing; Step 4: Finish the work inside the mold, cut off excess fabric strips, apply paint putty, and let it dry in the shade to take shape.
[0006] As a preferred technical solution of this application, the diameter of the reserved hole on the jade component matches the diameter of the reserved hole on the body; the diameter of the small round piece of the ramie cloth rivet is 4 mm larger than the diameter of the jade component hole, and the width of the cloth strip is 6-8 mm larger than the diameter of the jade component hole.
[0007] As a preferred technical solution of this application, the base is a lacquer-coated base or a wooden base; the number of reserved holes at the bottom of the base increases with the size of the base, and each reserved hole corresponds to a ramie rivet; the reserved holes of the jade component are opened in the middle or edge of the jade component, and the axis of the hole is perpendicular to the joint surface between the jade component and the base; the positions of the reserved holes at the bottom of the base correspond one-to-one with the positions of the reserved holes of the jade component.
[0008] As a preferred technical solution of this application, the thickness of the riveting surface of the jade component and the base body does not exceed 1 mm; when the size of the object increases, the thickness of the jade bonding surface increases accordingly; the reserved hole at the bottom of the base body is a through hole, and its thickness direction is consistent with the wall thickness direction of the base body; the reserved hole of the jade component is a countersunk hole or a through hole, used to accommodate the head of the ramie cloth rivet.
[0009] As a preferred technical solution of this application, in the riveting and fixing step, the joint area between the jade component and the body is also coated with a mixture of lacquer, glutinous rice flour and tile ash. After pressing and bonding, the excess lacquer is removed, so that the joint surface between the jade component and the body forms a sealed and firm adhesive layer.
[0010] As a preferred technical solution of this application, the length of the ramie rivet is cut according to the thickness of the body and the thickness of the jade component; after the rivet passes through the interior of the body, the excess cloth strip at the tail end is cut off and tightened, and the cloth strip is pulled apart to the left and right and coated on the surface of the body with a mixture of lacquer, glutinous rice flour and tile ash, so that the ramie rivet and the interior of the body form a mechanical anchor.
[0011] As a preferred technical solution of this application, the process can be riveting in the forward direction or in the reverse direction, and the riveting direction is selected according to the design of the object; when riveting in the forward direction, the head of the ramie cloth rivet is located on the outside of the jade component; when riveting in the reverse direction, the head of the ramie cloth rivet is located on the inside of the body.
[0012] As a preferred technical solution of this application, the small round piece of the ramie rivet is made by coating ramie coarse cloth with lacquer and glutinous rice flour mixture and then drying it in the shade. The small round piece serves as the head of the rivet. The long strip of ramie cloth wrapped around the small round piece serves as the shank of the rivet. The shank is coated with lacquer and then passes through a hole. After curing, it forms a rigid connector.
[0013] As a preferred technical solution of this application, the reserved holes at the bottom of the body are located at the center and around the contact area between the body and the jade component, and multiple reserved holes are arranged in an array or ring; the reserved holes on the jade component correspond one-to-one with the reserved holes on the body, and the hole diameter tolerance is ±0.5 mm.
[0014] As a preferred technical solution of this application, the process is applicable to a variety of large-sized lacquer-jade fusion objects other than cups, including but not limited to plates, bottles, boxes, and ornaments; and the number of openings on the bottom of the body and the jade components is proportional to the size of the object, with no less than 2 openings on a single object and a maximum number of openings not exceeding 50.
[0015] Compared with the prior art, the beneficial effects of the present invention are: The method employs ramie rivets to mechanically embed and secure the jade components and the pre-drilled holes in the base, forming a structural connection rather than relying solely on adhesive interfaces. This significantly improves tensile and shear strength and long-term reliability. Furthermore, this method is not strictly limited by the thickness of the jade material, its shape, or the type of base. The number of openings at the bottom of the base and in the middle of the jade components can be appropriately increased as the base size increases. Multiple pre-drilled holes are arranged in an array or ring and correspond one-to-one. Each hole is secured with ramie rivets for multi-point riveting. The riveting surface thickness does not exceed 1 mm, and the number can be increased appropriately for larger objects. This makes it suitable for various large-sized lacquer-jade fusion objects such as plates, bottles, boxes, and ornaments, supporting various base materials such as lacquerware and wood, as well as mass production.
