Description

Technical Field

[0001] This application relates to the field of cargo storage technology, specifically to a novel environmentally friendly coated wooden box. Background Technology

[0002] Wooden crates are commonly used packaging materials in the transportation and storage of goods, and are applied in machinery, chemical, electronics, hardware, and other fields. Traditional wooden crates are difficult to recycle and clean after use, and surface stains and impurities are hard to remove, resulting in low utilization of packaging materials. This necessitates the frequent manufacture of new wooden crates, increasing production costs and wasting resources.

[0003] Some manufacturers produce wooden crates with protective layers. For example, patent CN212638454U discloses a waterproof plywood crate. The bottom of the crate has a base plate, and the upper part of the base plate has side plates on all four sides. The upper part of the side plates is fitted with a cover. The outer wall of the side plates is made of plywood, and the plywood is coated with a water-based transparent varnish. The outer part of the water-based transparent varnish is covered with a plastic film. The inner wall of the side plates is made of tar paper. The four corners of the crate are covered with galvanized iron sheets. The interior of the crate has a storage cavity, and the bottom of the storage cavity has a drying cavity. The top of the drying cavity has a support plate with several ventilation holes arranged in a rectangular array. The top of the support plate has a corrugated board with several through holes arranged in a rectangular array.

[0004] This solution involves attaching plastic film and tar paper to the outer and inner walls of the wooden crate to make it waterproof and stain-resistant. However, the plastic film and tar paper are easily damaged and can easily generate debris, which can contaminate the goods inside the crate. Summary of the Invention

[0019] Preferably, the structural reinforcement coating is a polyurethane-silica nanocomposite coating.

[0020] Preferably, the thickness of the protective coating is 100-150 μm.

[0021] This application has at least the following beneficial effects:

[0022] The hydrophobic and stain-resistant properties of the protective coating make it easy to clean stains and impurities on the surface of the wooden crates. During recycling, most stains can be removed simply by wiping or rinsing, reducing cleaning difficulty and cost, and facilitating recycling and cleaning. Moreover, the recycled wooden crates can be reused multiple times, improving the utilization rate of packaging materials, reducing the number of new wooden crates to be manufactured, thereby reducing the amount of raw materials such as wood used and lowering production costs.

[0026] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0027] In the description of this application, it should be understood that if terms such as "length", "width", "thickness", "upper", "lower", "vertical", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0028] Furthermore, where the terms "first," "second," and "third" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first," "second," and "third" may explicitly or implicitly include at least one of those features. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0031] It should be noted that if an element is referred to as being "fixed to," "set on," or "contained on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0032] The embodiments of this application are described in detail below with reference to the accompanying drawings.

[0033] like Figure 1 As shown in the embodiment of this application, a novel environmentally friendly coated wooden box is provided, including a box body 1, a protective coating, and an adhesive coating 3. The protective coating is applied to the inner and outer walls of the box body 1, and the protective coating includes a resin coating 2, which has waterproof and stain-resistant properties. The adhesive coating 3 is applied between the box body 1 and the protective coating, and the adhesive coating 3 is a nano-composite coating.

[0034] This embodiment of the novel environmentally friendly coated wooden crate is composed of multiple wooden boards. Suitable wood is selected for the crate construction to ensure a sturdy structure and dimensional accuracy. The surface of the crate is pre-treated, such as by sanding and cleaning, to ensure a smooth and clean surface, facilitating coating application. Each wooden board is coated with a protective coating on both its inner and outer sides. The resin coating 2 within the protective coating provides waterproofing and stain resistance, while the adhesive coating 3 uses nanomaterials to enhance the bond between the crate surface and the protective coating. This ensures a tight bond between the coating and the crate, preventing damage or peeling, while also providing a degree of waterproof protection. This significantly increases the number of times the crate can be reused and prevents contamination of goods.

[0035] In a preferred embodiment, the resin coating 2 is a cyclic olefin amorphous transparent copolymer coating. Cyclic olefin amorphous transparent copolymer coatings possess excellent heat resistance, corrosion resistance, and impact resistance, and offer a high cost-performance ratio.

[0036] In a preferred embodiment, the adhesive coating 3 is a composite coating of white latex, nano-sized silicate particles, and a crosslinking agent. The adhesive coating 3 uses modified white latex as the base material, and the addition of nano-sized silicate particles and a crosslinking agent significantly improves the coating's permeability and bonding strength. Compared to traditional single-layer paint coatings, this design increases the adhesion between the coating and the wood by 2.5 times, effectively preventing coating peeling during use. Furthermore, the adhesive coating 3 is applied using a dip-coating process, ensuring that the coating can fully penetrate the microporous structure of the wood surface, forming a dual bonding mechanism of mechanical interlocking and chemical bonding.

[0037] In a preferred embodiment, the thickness of the adhesive coating 3 is 50-80 μm. In practical applications, controlling the thickness of the adhesive coating 3 between 50-80 μm ensures sufficient bonding strength without excessively increasing material costs.

[0038] In a preferred embodiment, the protective coating further includes a transition coating 4, which is applied between the adhesive coating 3 and the resin coating 2. The transition coating 4 is made of acrylic-modified resin, providing a good adhesion base for the outer coating.

[0039] In a preferred embodiment, the protective coating further includes a structural reinforcement coating 5, which is applied between the transition coating 4 and the resin coating 2. The structural reinforcement layer utilizes a nanocomposite material, improving adhesion and mechanical strength. Specifically, the structural reinforcement layer uses a polyurethane-silica nanocomposite material, wherein nano-silica particles are uniformly dispersed in the polyurethane matrix, forming a "brick-and-mortar" structure. This more than doubles the mechanical strength of the coating, significantly improving the impact and wear resistance of the wooden crate.

[0040] In a preferred embodiment, the thickness of the protective coating is 100-150 μm. By precisely controlling the thickness ratio and curing conditions of each sublayer, the performance of each sublayer is ensured to be optimal.

[0041] During the spraying process, the modified white latex is first evenly applied to the surface of the wooden box. After curing, the protective coating is sprayed sequentially. During spraying, the spraying pressure, speed, and angle are carefully controlled to ensure uniform coating thickness. After coating, the wooden box is allowed to dry and cure in a suitable environment to allow the coating to fully perform its functions.

[0042] The above embodiments are used to further illustrate this application, but do not limit this application to these specific implementations. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be understood as falling within the protection scope of this application.
