Description

Technical Field

[0001] The present invention relates to a high-performance bamboo recombined container and a preparation method thereof, belonging to the technical field of cargo transportation equipment, and is particularly applicable to scenarios such as sea transportation, land transportation, and warehousing of various goods. The purpose of this invention is to utilize the excellent properties of bamboo recombined materials to develop a container that can be used for ultra-long and large-volume goods transportation, providing a high-performance, environmentally friendly, and economical container solution for cargo transportation. Background Art

[0002] In the modern cargo transportation system, as a key transportation equipment, the performance and material selection of containers are crucial. Traditional steel containers have been widely used for a long time, but with the development of the industry, their inherent defects have gradually emerged.

[0003] In terms of weight, the density of steel is as high as about 7.85 g / cm 3 , which makes the self-weight of steel containers extremely large. Taking a common 20-foot standard steel container as an example, its own weight usually reaches about 2.3 tons. During the actual cargo transportation process, this additional self-weight not only occupies the limited load capacity of the transportation tool, directly resulting in a reduction in the effective cargo capacity, but also significantly increases the transportation cost. In road transportation, vehicles need to consume more fuel to carry the weight of the container. Taking a truck with a load capacity of 10 tons as an example, if it is equipped with a traditional steel container, due to the excessive self-weight of the container, the actual cargo capacity may be reduced by 1 - 2 tons, and the fuel consumption will increase by 10% - 15%, greatly increasing the transportation cost.

[0004] The poor corrosion resistance of steel is also a major problem. In a humid, salt-containing marine transportation environment or industrial polluted areas, steel is extremely prone to oxidation reaction and rusting. Generally, after 3 - 5 years of use, obvious rusting phenomena will appear on steel containers, and maintenance work such as rust removal and painting is required. Each maintenance not only requires a large amount of manpower and material resources, purchasing materials such as rust removal equipment and protective coatings, but also needs to pay the labor remuneration of workers. According to statistics, the cost of each maintenance accounts for about 5% - 10% of the container cost. Moreover, frequent maintenance will cause the container to be out of use, affecting its usage efficiency and reducing the continuity and timeliness of transportation.

[0005] In terms of resources and environmental protection, steel production is a high-energy-consuming and highly polluting process. Producing 1 ton of steel requires consuming about 1.5 - 2 tons of iron ore and 0.5 - 0.6 tons of coal, while emitting 1.6 tons of carbon dioxide, and also generating a large amount of pollutants such as waste residue and waste gas. With the increasing global attention to environmental protection and sustainable development, the disadvantages of traditional steel containers in terms of resource consumption and environmental protection are becoming increasingly prominent, not meeting the development requirements of the modern society for green and low-carbon economy.

[0006] Although there are currently attempts to improve containers by using lightweight materials such as aluminum alloys, the cost of aluminum alloys is high, which is 20%-30% higher than that of steel. Moreover, aluminum alloys have certain limitations in terms of strength and impact resistance, and it is difficult to meet the requirements of containers in complex usage environments. For example, when being collided during loading and unloading, aluminum alloy containers are more likely to deform and be damaged. The application research of natural materials such as bamboo in the field of containers is still in its infancy, lacking mature and systematic technical solutions, and there is currently no product and technical standard that can be applied on a large scale.

[0007] Bamboo recombined lumber is a bamboo-based profile formed by breaking bamboo into bamboo strips or loosening it into continuous bamboo bundles that maintain the original arrangement of fibers, or removing the organic matter to obtain loose reticular bamboo fiber bundles or pure fibers, and then being processed (such as carbonization, etc.), dried, sized, assembled into a blank and pressed. The commonly used methods for destroying or removing the organic matter between fibers are mechanical methods and chemical methods. The mechanical method destroys the organic matter between fibers, while the chemical method directly removes the organic matter through chemical treatment, leaving fiber bundles, and materials with better performance can be produced. The raw materials of bamboo recombined lumber are widely sourced and are not affected by the diameter of the original bamboo. The existing technology has also achieved a certain degree of automated production. It has excellent mechanical properties and has good application prospects in the structural system. Summary of the Invention

[0008] In order to solve the above problems, the present invention provides a high-performance bamboo recombined lumber container and a preparation method, which give full play to the advantages of bamboo recombined lumber such as lightweight, high strength, corrosion resistance, and environmental protection, and effectively solve the problems existing in traditional steel containers, such as large weight, easy corrosion, and large resource consumption.

[0011] Step 1: Prepare high-performance bamboo recombined structural materials and process them into container combined components according to design requirements; the bamboo recombined structural materials are bamboo profiles formed by splitting bamboo into bamboo strips or loosening them into continuous bamboo bundles that maintain the original arrangement of fibers, or loose reticular bamboo fiber bundles or pure fibers after removing organic matter, and then processed (such as carbonization, etc.), dried, glued, assembled and formed, and finally pressed.

[0012] Step 2: Connect the longitudinal short beam (3-1) at the bottom of the side span, the corner post for door connection (1), and the transverse short beam (5-1) at the bottom of the door connection with the glass fiber steel sleeve bolt connector (8-2) with corner pieces at the bottom. Connect the longitudinal short beam (3) at the bottom and the middle column (2-3) in contact with the ground with the glass fiber steel sleeve bolt connector (8-4) with corner pieces at the bottom or the right-angle glass fiber steel filling plate bolt connector (9). Ensure that the lower ends of the glass fiber steel sleeve bolt connector (8-2) with corner pieces at the bottom and the middle column (2-3) in contact with the ground are on the same horizontal plane, and jointly transfer the load to the ground.

[0013] Step 3: Connect the two ends of the middle transverse short beam (5-4) and the bottom ends of the non-grounded longitudinal side middle columns (2-1) to the longitudinal short beam (3) at the bottom with the right-angle glass fiber steel filling plate bolt connector (9). Connect the two ends of the middle longitudinal short beam (6) at the bottom to the transverse short beam (5). Both the left and right sides at the bottom of the middle column (2-3) in contact with the ground are connected to the longitudinal short beam (3) at the bottom through diagonal braces (7), and the two ends are connected with the diagonal glass fiber steel filling plate bolt connector (10) to form a triangular shape.

[0014] Step 4: Connect the left top longitudinal long beam (4-1) and the right top longitudinal long beam (4-2) with the glass fiber steel sleeve bolt connector (8-3) without corner pieces to form the top longitudinal long beam (4). Connect the top longitudinal long beam (4), the corner post (1) with the glass fiber steel sleeve bolt connector (8-1) with corner pieces at the top to the transverse short beam (5-2) at the top of the door connection and the transverse short beam (5-3) at the top of the connection plate respectively. Connect the two ends of the middle transverse short beam (5-4) to the top longitudinal long beam (4) with the right-angle glass fiber steel filling plate bolt connector (9).

[0015] Step 5: Connect the corner post (1) and the transverse short beam (5-2) at the top of the door connection to the top longitudinal long beam (4) through diagonal braces (7). Connect the corner post (1-2) of the connection plate and the transverse short beam (5-3) at the top of the connection plate. Both ends of all diagonal braces (7) are connected to the beam or column with the diagonal glass fiber steel filling plate bolt connector (10) to form a triangle.

[0016] Step 6: Install the bamboo recombined wood bottom plate (12) inside the bamboo recombined wood frame structure, and install the bamboo recombined wood top plate (13), bamboo recombined wood longitudinal side plates (14), and bamboo recombined wood transverse side plates (15) outside the bamboo recombined wood frame structure. These plates are all two-way bamboo recombined wood fiberboards; install side-facing double doors (11-1) between the connecting door corner columns (1-1), and install a top surface automatic sliding door (11-2) at the exact middle position on the top of the bamboo recombined wood frame structure;

[0017] Step 7: Treat the surface of the bamboo recombined wood plates with PVDF / FSR composite microcapsule enhanced superhydrophobic multifunctional coating technology. Select polyvinylidene fluoride (PVDF) and fluorosilicone resin (FSR) of type YBS-S-860 as the matrix resins, with their mass fractions being 45% and 55% respectively. Combine with Covestro's N3390 curing agent to promote the resin to cure into a film. Add carbon nanofibers (CNF) to enhance the mechanical strength of the coating, and at the same time introduce two types of microcapsules, namely EDTA-Zn / PU@SiO2 microcapsules and FSO / PU@SiO2 microcapsules; fill the seams of the container with silicone sealant to prevent moisture, dust, etc. from entering.

[0018] For the said bamboo recombined wood frame structure, if it is a 40-foot standard marine container, it can be composed of 4 corner columns (1), 19 middle columns (2), 10 bottom side longitudinal short beams (3), 4 top side longitudinal long beams (4), 21 transverse short beams (5), 10 bottom middle longitudinal short beams (6), 24 diagonal braces (7) and connecting parts; the number of components can be increased or decreased according to the actual load-bearing and application conditions.

[0019] The materials of the said side-facing double doors (11-1) and the top surface automatic sliding door (11-2) can be metal, or can adopt one or a combination of bamboo laminated lumber, bamboo recombined wood, bamboo woven glued wood, bamboo plastic composite, bamboo particleboard composite, bamboo shred profile, wood, straw; the top surface automatic sliding door (11-2) can also not be installed according to the actual situation and be replaced with a plate.

[0020] The glass fiber in the said fiberglass sleeve bolt connector (8), right-angle fiberglass filling plate bolt connector (9), and bevel fiberglass filling plate bolt connector (10) can be replaced with one or a combination of carbon fiber, aramid fiber, and basalt fiber.

[0021] The said bamboo recombined wood can also be replaced with one or a combination of bamboo laminated lumber, bamboo woven glued wood, bamboo plastic composite, bamboo particleboard composite, bamboo shred profile, wood, bamboo-wood composite, straw according to the use function and requirements.

[0022] The arrangement quantity and mode of each component of the bamboo recombined wood frame structure can be increased or decreased according to the weight tolerance and usage conditions; the bamboo recombined wood frame structure can also be used as a house.

[0023] The PVDF / FSR composite microcapsule enhanced superhydrophobic multifunctional coating technology has superhydrophobic properties and multiple functions such as wear resistance, self-healing, anti-corrosion, scale inhibition, and ultraviolet resistance; the filling depth of the silicone sealant at each splicing gap of the container is not less than 10 mm.

[0024] After assembling the bamboo recombined wood container frame, use stainless steel kits and stainless steel nails to fix the side facing doors (11-1), top automatic opening doors (11-2), bamboo recombined wood bottom plates (12), bamboo recombined wood top plates (13), bamboo recombined wood longitudinal side plates (14), and bamboo recombined wood transverse side plates (15) on the bamboo recombined wood frame, and apply sealant. The side facing doors (11-1), top automatic opening doors (11-2), bamboo recombined wood bottom plates (12), bamboo recombined wood top plates (13), bamboo recombined wood longitudinal side plates (14), and bamboo recombined wood transverse side plates (15) are all made of two-way bamboo recombined wood fiberboards. The thickness of each layer is not less than 5 mm, and there are at least 4 layers of two-way bamboo recombined wood fiberboards. During the pressing process, apply a certain pressure and temperature to make the fiberboards closely combined, improving the overall strength and sealing performance of the boards. When installing the bamboo recombined wood doors, use stainless steel metal kits to ensure that the doors open and close flexibly and smoothly, and at the same time ensure the sealing performance between the doors and the frame. When installing the bamboo recombined wood bottom plates, top plates, and side plates, use stainless steel nails for fixation, and control the nail spacing between 100-150 mm to ensure that the boards are fixed firmly. During the installation process, carefully check each board to ensure no cracks or deformations. When applying the sealant, ensure that the sealant is uniform and continuous, and the filling depth is not less than 10 mm to prevent moisture and dust from entering the interior of the container.

[0025] A high-performance protective coating was constructed on the surface of bamboo recombinant material by spraying process. The coating is based on polyvinylidene fluoride (PVDF) and YBS-S-860 fluorosilicone resin (FSR), and is modified by adding carbon nanofiber (CNF), EDTA-Zn / PU@SiO2 microcapsules and FSO / PU@SiO2 microcapsules to form a composite coating with unique properties. The coating performance is optimized by precisely controlling the proportion of each component. PVDF and FSR are matched in a mass ratio of 45% and 55%, and the basic film-forming properties of the coating are guaranteed with Covestro N3390 curing agent. Appropriate addition of CNF enhances the mechanical strength of the coating; EDTA-Zn in EDTA-Zn / PU@SiO2 microcapsules plays the role of chelating scale ions and improving scale inhibition performance; FSO / PU@SiO2 microcapsules release lubricant FSO under pressure to enhance wear resistance. The coating has excellent comprehensive properties: excellent superhydrophobicity, strong mechanical durability, good chemical stability, self-repairing ability, good anti-icing and de-icing performance, and can effectively meet the needs of using containers in cold environments.

[0026] Silicone sealant is used to seal the joints of containers, such as the joints of columns, beams, longitudinal beams, diagonal braces (7), etc. The sealant should have good elasticity, aging resistance and waterproof properties, and the filling depth should be no less than 10mm to ensure that the gaps are completely sealed to prevent moisture, dust, etc. from entering the container and affecting the performance of the bamboo recombinant material.

[0027] The beneficial effects of the present invention are:

[0028] Lightweight and efficient: The density of bamboo recombinant wood is only about 1 / 5-1 / 4 of that of steel. This feature makes the 40-foot bamboo recombinant wood frame container show great advantages in weight. The deadweight of a traditional 40-foot steel container is usually around 4-5 tons, while the deadweight of this bamboo recombinant wood frame container can be reduced to about 3 tons. The reduction in deadweight directly leads to a significant increase in effective cargo capacity. Compared with traditional steel containers, the effective cargo capacity of a single container can be increased by more than 1.5 tons. During transportation, fuel consumption is closely related to the load of the vehicle or ship. Since bamboo recombinant wood containers are lighter, fuel consumption during transportation can be reduced by about 10%-15%.

[0029] Reliable strength: The specially processed bamboo recombinant material has excellent mechanical properties such as tensile strength and compressive strength. Through scientific and reasonable frame structure design and reliable connection methods, this 40-foot bamboo recombinant material container can fully meet the various strength requirements of international container standards. In actual use, whether it is the stacking of goods, vibration during transportation, or force during lifting operations, the container can stably bear the load and effectively ensure the safety of goods during transportation.

[0030] Superior corrosion resistance: Bamboo recombined lumber itself has a certain degree of corrosion resistance. Coupled with a carefully designed surface protection coating and sealing treatment, its corrosion resistance in harsh environments far exceeds that of steel containers. In the humid and high-salt spray environment of ocean transportation, generally, after 3 - 5 years of use, a 40-foot steel container requires large-scale anti-corrosion maintenance work, including rust removal and repainting, and each maintenance is costly. In contrast, this 40-foot bamboo recombined lumber frame container, due to its excellent corrosion resistance, can be continuously used for 8 - 10 years without large-scale anti-corrosion treatment, and the maintenance cost can be reduced by more than 50%. This not only reduces the input of manpower, material resources and financial resources required for maintenance, but also greatly improves the use efficiency of the container and reduces the downtime caused by maintenance.

[0031] Environmentally friendly and sustainable: Bamboo grows extremely fast and can reach a height of 10 - 20 meters in 3 - 4 months. It is a high-quality resource that can be sustainably utilized. Using bamboo recombined lumber to make 40-foot containers can significantly reduce the dependence on non-sustainable resources such as steel. The production of steel not only consumes a large amount of natural resources such as iron ore and coal, but also generates a large amount of greenhouse gases such as carbon dioxide. In contrast, bamboo can absorb a large amount of carbon dioxide during its growth process, playing a role as a carbon sink, and its carbon emissions during the processing are relatively low. Therefore, promoting the use of 40-foot bamboo recombined lumber containers helps to drive the container industry towards the direction of low-carbon environmental protection, conforms to the global sustainable development trend, and is of great significance to environmental protection.

The left and right sides at the bottom of the grounded middle columns (2-3) are both connected to the bottom side longitudinal short beams (3) through diagonal braces (7), and the two ends are connected by diagonal-angle fiberglass steel filling plate bolt connectors (10) to form a triangular shape; Step 4: Use fiberglass steel sleeve bolt connectors without corner pieces (8-3) to connect the left top side longitudinal long beam (4-1) and the right top side longitudinal long beam (4-2) to form the top side longitudinal long beam (4); use fiberglass steel sleeve bolt connectors with corner pieces at the top (8-1) to connect the top side longitudinal long beam (4), corner columns (1) to the door-connected top transverse short beams (5-2) and the connection plate top transverse short beams (5-3) respectively; use right-angle fiberglass steel filling plate bolt connectors (9) to connect the two ends of the middle transverse short beams (5-4) to the top side longitudinal long beam (4) respectively; Step Five: Use diagonal braces (7) to connect the corner columns (1) and the transverse short beams (5-2) at the top of the access door to the longitudinal long beams (4) at the top edge. Connect the corner columns (1-2) of the connecting plate and the transverse short beams (5-3) at the top of the connecting plate. Both ends of all diagonal braces (7) are connected to the beams or columns through diagonal fiberglass filling plate bolt connectors (10) to form triangles. Step Six: Install the bamboo recombined wood bottom plate (12) inside the bamboo recombined wood frame structure, and install the bamboo recombined wood top plate (13), bamboo recombined wood longitudinal side plates (14) and bamboo recombined wood transverse side plates (15) outside the bamboo recombined wood frame structure. These plates are all two-way bamboo recombined wood fiberboards. Install side facing double doors (11-1) between the corner columns (1-1) of the access door, and install a top surface automatic sliding door (11-2) at the exact middle position on the top of the bamboo recombined wood frame structure. Step Seven: Treat the surface of the bamboo recombined wood plates with PVDF / FSR composite microcapsule enhanced superhydrophobic multifunctional coating technology. Select polyvinylidene fluoride (PVDF) and fluorosilicone resin (FSR) of type YBS-S-860 as the matrix resins, and their mass fractions are 45% and 55% respectively. Combine with the N3390 curing agent of Covestro to promote the resin to cure into a film. Add carbon nanofibers (CNF) to enhance the mechanical strength of the coating, and introduce two kinds of microcapsules at the same time, namely EDTA-Zn / PU@SiO2 microcapsules and FSO / PU@SiO2 microcapsules. Fill the seams of the container with silicone sealant to prevent moisture, dust, etc. from entering.
