Description

Technical Field

[0001] This utility model relates to the field of corner protector technology, and in particular to anti-rust paper corner protectors for packaging. Background Technology

[0002] After leaving the factory, steel coils need to be packaged and then transported to different places. Steel coils generally need to be fitted with paper corner protectors on both sides to protect the edges and corners when the steel coils are packaged as bare coils. Although the existing corner protectors can protect the edges and corners of the steel coils, they cannot effectively prevent the steel coils from rusting, especially in rainy weather, when the steel coils are more prone to rusting, leading to a reduction in product quality. Summary of the Invention

[0003] The purpose of this utility model is to provide rust-proof paper corner protectors for packaging in order to solve the above-mentioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The packaging rust-proof paper corner protector includes an annular edge protector. Multiple protective blocks are evenly distributed at one end of the annular edge protector, and the multiple protective blocks form an annular protective plate. Multiple rows of spherical grooves are evenly opened on the outer side of the annular edge protector, and rust-proof balls are provided in the spherical grooves.

[0005] Preferably, the outer side of the rust-preventive ball is coated with a VCI corrosion inhibitor.

[0006] Preferably, the annular edge protector is made of kraft paper.

[0007] Preferably, the kraft paper includes an upper waterproof layer, an upper flame-retardant layer is fixedly connected to the bottom side of the upper waterproof layer, a tensile layer is provided on the bottom side of the upper flame-retardant layer, a lower flame-retardant layer is provided on the bottom side of the tensile layer, and a lower waterproof layer is provided on the bottom side of the lower flame-retardant layer.

[0008] Preferably, the tensile layer is composed of a first helical column and a second helical column, wherein the first helical column is arranged in multiple parallel rows, and the second helical column is arranged in multiple parallel rows, and the first helical column and the second helical column are perpendicular to each other and intertwined.

[0009] Preferably, both the first and second spiral columns are made of polyethylene material.

[0010] Preferably, both the first and second spiral columns are made of polyethylene material.

[0011] Preferably, both the upper flame-retardant layer (6) and the lower flame-retardant layer are made of asbestos fiber.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: This application features multiple rust-removing balls evenly distributed on a ring-shaped cover. These balls contain VCI corrosion inhibitors. In a sealed environment, the VCI corrosion inhibitors continuously and in an adjustable manner evaporate, ensuring that any gaps within the working unit are filled with a mixed gas containing VCI rust-preventing agents. When this gas encounters a metal surface, it adsorbs onto it, forming a dense protective film only one or a few molecules thick. This protective film effectively isolates the metal surface from contact with moisture, oxygen, and other harmful atmospheric corrosive factors, inhibiting the electrochemical reactions that promote metal corrosion, thereby achieving optimal rust prevention and improving the product's corrosion resistance.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 This utility model provides a technical solution: The rust-proof paper corner protector for packaging includes an annular edge protector 1. Multiple protective blocks 2 are evenly distributed at one end of the annular edge protector 1, forming an annular protective plate. Multiple rows of spherical grooves 3 are evenly distributed on the outer side of the annular edge protector 1. Rust-proof balls 4 are installed in the spherical grooves 3, and the outer side of the rust-proof balls 4 is covered with VCI corrosion inhibitors. In a sealed environment, the VCI corrosion inhibitors continuously and volatile through their own adjustable mechanism, ensuring that any gaps within the working unit are filled with a mixed gas containing VCI rust-proofing factors.
