Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating and packaging technology, specifically to an anti-flocculation recyclable water-based graphene packaging barrel. Background Technology
[0002] Graphene zinc powder paint, as a high-performance coating, has broad application prospects in fields such as corrosion prevention and conductivity. However, due to the large specific surface area and strong van der Waals forces of graphene, flocculation is prone to occur during storage and transportation, leading to a decline in the performance of the coating and affecting its effectiveness.
[0003] Traditional paint packaging containers are typically made of ordinary plastic or metal, and are not specifically designed to address the graphene flocculation problem. Furthermore, after use, these containers often leave a large amount of paint residue on their inner walls, making cleaning difficult and increasing the cost and complexity of recycling. Utility Model Content
[0004] The purpose of this invention is to provide an anti-flocculation, recyclable water-based graphene packaging bucket to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-flocculation recyclable water-based graphene packaging bucket, comprising:
[0006] Bucket body and bucket lid;
[0007] Both the barrel body and the barrel lid are made of plastic, and the barrel lid is detachably connected to the top of the barrel body;
[0008] The inner wall of the barrel is coated with a nano anti-stick coating.
[0009] Preferably, the nano-anti-stick coating comprises a composite coating underlayer and a fluorinated silane modified surface layer.
[0010] Preferably, the top of the outer wall of the barrel is provided with an external thread, and the inner wall of the barrel lid is provided with an internal thread that matches the external thread.
[0011] Preferably, a spiral stirring blade is fixedly connected to the bottom of the bucket lid.
[0012] Preferably, the barrel contains a plurality of dispersion balls, which are porous in surface and filled with a polymeric dispersant.
[0013] Preferably, the dispersion spheres are made of ceramic material.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] The nano-anti-stick coating on the inner wall of the container effectively inhibits the flocculation of graphene. This coating significantly reduces paint residue on the inner wall, making cleaning easier and faster. The container body and lid are made of recyclable plastic, making the packaging easy to disassemble and recycle. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.
[0023] Example 1:
[0024] Please see Figure 1-4 This utility model provides a technical solution: an anti-flocculation recyclable water-based graphene packaging barrel, comprising: barrel body 1 and barrel lid 2;
[0025] Both the barrel body 1 and the barrel lid 2 are made of plastic, and the barrel lid 2 is detachably connected to the top of the barrel body 1; the inner wall of the barrel body 1 is coated with a nano anti-stick coating 4. The nano anti-stick coating 4 includes a composite coating base layer and a fluorinated silane modified surface layer.
[0026] Analysis of the above: The nano-anti-stick coating 4 features a silica-titanium composite coating (an existing material) as the bottom layer. This silica-titanium composite coating has extremely low surface energy, less than or equal to 20 mN / m, effectively reducing the adsorption force between graphene and the barrel wall, thus decreasing graphene adhesion and aggregation. The microstructure of the nano-coating exhibits a roughness similar to the surface of a lotus leaf, creating a "lotus effect," making it difficult for the coating to adhere to the barrel wall and further inhibiting graphene flocculation. The fluorinated silane-modified surface layer has good hydrophobicity and oleophobicity, with a contact angle greater than or equal to 110°. This coating significantly reduces the amount of coating residue on the barrel wall; in standard wiping tests, the residue is less than or equal to 0.3 g / m. 2 When cleaning the packaging drums, simply rinse with a small amount of detergent and water to easily remove residual paint from the drum walls, significantly improving cleaning efficiency.
[0027] Example 2:
[0028] Please see Figure 1-4 Based on Embodiment 1, this utility model provides a technical solution: the top of the outer wall of the barrel 1 is provided with an external thread 3, and the inner wall of the barrel cover 2 is provided with an internal thread that matches the external thread 3.
[0029] Analysis of the above content: Using a threaded connection, the screw can be used for installation and disassembly.
[0030] Example 3:
[0031] Please see Figure 1-4 Based on Embodiment 2, this utility model provides a technical solution: a spiral stirring blade 6 is fixedly connected to the bottom of the bucket lid 2.
[0032] Analysis of the above content: When the lid 2 is disassembled and opened by the screw, the rotation of the lid 2 will drive the spiral stirring blade 6 to rotate. The rotation of the spiral stirring blade 6 and the spiral guide plate can stir the coating in the bucket, so that the graphene is evenly dispersed in the coating, effectively solving the problem of graphene flocculation. This spiral stirring blade 6 can automatically stir every time the lid 2 is opened, which is convenient and practical.
[0033] Example 4:
[0034] Please see Figure 1-4This utility model provides a technical solution based on Embodiment 2: the barrel 1 contains a plurality of dispersion balls 5, the dispersion balls 5 have a porous surface, and the pores of the dispersion balls 5 are filled with a polymeric dispersant. The dispersion balls 5 are made of ceramic material.
[0035] Analysis of the above: The dispersion balls 5 have a diameter of 3-5 mm. These dispersion balls 5 are pre-adsorbed with polymeric dispersants, such as polycarboxylate dispersants. When the coating is poured into the container 1, as the coating shakes and flows, the dispersion balls 5 roll within the container 1, slowly releasing the dispersant to continuously disperse the graphene and prevent flocculation. Moreover, the rolling of the dispersion balls 5 also provides a certain stirring effect, further promoting the uniformity of the coating.
[0036] Further expansion: A discharge port can be added to the outer wall of the barrel 1. Under normal circumstances, the discharge port is closed. When in use, the discharge port can be opened to output the paint directly, which is convenient for pouring out (the barrel cover 2 and the spiral stirring blade 6 can be rotated in advance to achieve the mixing effect before discharge).
[0037] A sealing ring is installed between the upper part of the barrel body 1 and the barrel lid 2 to prevent leakage.
[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.

Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model, and no reference numerals in the claims should be considered as limiting the scope of the claims.
