Description

Technical Field

[0001] The utility model relates to the technical field of corner guard paper, in particular to high-strength corner guard paper. Background Technique

[0002] Corner guard paper, also known as edge board, is one of the most popular packaging products in the world, used to replace wooden packaging and other bulky packaging methods. It is made of waste paper and has the characteristics of low price, light weight, firmness, and compliance with environmental protection requirements. The main purchasers of corner guard paper are the construction industry, the aluminum industry, the steel industry, and other metal industries. In addition, it also includes the brick-making industry, the candy industry, frozen foods, daily necessities, household appliances, chemical products, pharmaceuticals, computers, and other high-tech products. This is because these products have a large number of surfaces and corners that need to be protected. In addition, corner guard paper can also be used in the transportation of fruits, not only playing a protective role, but also enabling the goods to ventilate during transportation.

[0003] Existing corner guard papers are all directly made of a single wood fiber. Such a material structure is not separately set, which will result in low strength in use and cannot meet the requirements. Moreover, corner guard papers are generally set at the bottom of the packaging box. Therefore, corner guard papers usually come into contact with the ground, which requires corner guard papers to have moisture-proof and insect-proof requirements. However, existing corner guard papers do not have the ability of moisture-proof and insect-proof, and need to be improved. Content of the Utility Model

[0004] The purpose of the utility model is to provide high-strength corner guard paper to solve the problems put forward in the above background technique.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] The present utility model provides a high-strength corner protection paper as Figures 1-4 shown, including a corner protection paper composite inner layer 1, an outer wear-resistant layer 2, a composite inner core 8, and a high-performance fiber inner layer 9. A reinforcing inner groove 5 is provided at the middle position inside the corner protection paper composite inner layer 1. A reinforcing cross plate 3 is provided inside the reinforcing inner groove 5. A plurality of reinforcing fins 4 are provided on both sides of the reinforcing cross plate 3. The plurality of reinforcing fins 4 are evenly separated and are located inside the corner protection paper composite inner layer 1. The corner protection paper composite inner layer 1 is composed of a moisture absorption ring 7 and a composite inner core 8, and the composite inner core 8 is located inside the moisture absorption ring 7.

[0021] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, for the high-strength corner protection paper of the present utility model, specifically,

[0022] Outer wear-resistant layers 2 are provided on both sides of the corner protection paper composite inner layer 1. The outer wear-resistant layer 2 is aramid paper, which is mainly made of aramid fibers. Aramid paper is also known as "polyarylamide fiber paper" and is made from aramid staple fibers and aramid precipitated fibers as papermaking raw materials, formed by inclined net papermaking and wet forming, and then obtained by hot pressing. Aramid paper inherits the advantages of aramid fibers, with a strength six times that of steel wire, a toughness twice that of steel wire, but a mass only about one-fifth of that of steel wire. Aramid paper also has very high chemical and physical stability, is resistant to acid and alkali corrosion, flame retardant and high temperature resistant, crack resistant and impact resistant, wear resistant with small deformation, and has good flame retardant insulation and a long service life.

[0023] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, for the high-strength corner protection paper of the present utility model, specifically, a plurality of sealing rubber rings 6 are provided on both sides of the inner wall surface of the reinforcing inner groove 5, and the outer sides of the sealing rubber rings 6 are fixedly bonded to the outer surface of the reinforcing cross plate 3.

[0024] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the high-strength corner protection paper of the present utility model. Specifically, the composite inner core 8 is composed of a high-performance fiber inner layer 9, a straw fiber layer 10, and an artemisia fiber layer 11. The high-performance fiber inner layer 9, the straw fiber layer 10, and the artemisia fiber layer 11 are adhesively arranged in a vertical structure in sequence. The high-performance fiber inner layer 9 of the present application is a composite material made by mixing textiles and pulp. It has multiple advantages such as light weight, high strength, waterproof, fireproof, corrosion-resistant, and wear-resistant. For specific details, reference can be made to various publicly available high-performance fiber paper-based functional materials.

[0025] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the high-strength corner protection paper of the present utility model. Specifically, the moisture absorption ring 7 is a sponge fiber ring, and the sealing rubber ring 6 is an annular ring composed of a rubber sealing strip.

[0026] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the high-strength corner protection paper of the present utility model. Specifically, the straw fiber layer 10 is made of straw pulp fiber, and the artemisia fiber layer 11 is made of artemisia pulp fiber. The straw fiber is rich in silicate, which can kill insects by destroying their outer shells. At the same time, because the straw fiber contains a large amount of alkaline substances, it can also prevent the growth of mold, thus avoiding mildew contamination caused by paper getting damp. The artemisia fiber layer 11 is made of 70% artemisia cellulose + 30% polyamide fiber. The artemisia fiber is made by modern extraction technology to effectively extract artemisia essential oil with antibacterial and aromatherapy effects. The essential oil is combined with cotton, lyocell fiber, viscose fiber, and polyamide materials in the form of microcapsules and embedded inside the fiber to form a fiber containing natural artemisia. It not only retains the original fiber's softness, comfort, moisture absorption, air permeability, coolness, and other properties, but also makes it have the unique advantages of antibacterial, sleep-aiding, and fragrant smell. Compared with chemical insecticides, the plant fibers used in the present application have many advantages. First, plant fibers are natural and have no chemical residues, which are harmless to human health. Second, plant fibers can be decomposed into organic matter and can also be used as fertilizers. Finally, using plant fibers can reduce environmental pollution and protect the balance of the ecosystem.

[0027] Working principle of the utility model: A reinforcing transverse plate 3 and reinforcing fins 4 are arranged inside the corner guard paper. The reinforcing transverse plate 3 and the reinforcing fins 4 penetrate the entire interior of the corner guard paper, thus greatly improving the support strength of the corner guard paper and effectively preventing the problem of deformation of the corner guard paper during use. At the same time, the composite inner layer 1 of the corner guard paper in this application is composed of a moisture absorption ring 7 and a composite inner core 8. The moisture entering the interior of the composite inner layer can be blocked by a sealing rubber ring 6. At the same time, the moisture absorption ring 7 adsorbs the moisture and liquid inside the paper. The composite inner core 8 of this application is composed of a high-performance fiber inner layer 9, a straw fiber layer 10, and an artemisia fiber layer 11. The high-performance fiber inner layer 9 can ensure the basic strength of the entire composite inner core 8, while the straw fiber layer 10 and the artemisia fiber layer 11 can be treated for insect prevention to avoid the bottom of the corner guard paper being eaten by insects.
