Description

Technical Field

[0001] This utility model relates to the field of fiber paperboard technology, and in particular to a fiber paperboard with flame-retardant properties. Background Technology

[0002] Fiberboard is a type of board material made from various cellulose materials such as waste paper, hemp, and wood through processing and pressing. The main raw materials for fiberboard include cellulose materials such as waste paper, hemp, and wood. These raw materials, after processing, can be made into fiberboard with excellent properties. With increasing environmental awareness and technological advancements, the production process and performance of fiberboard will continue to improve. Fiberboard will place greater emphasis on environmental protection, energy conservation, and sustainable development, while expanding its application areas and market reach.

[0003] In actual use, existing cardboard has poor wear and tear resistance and is easily worn and damaged, thus losing the protective function of the packaging made of cardboard. This is not conducive to the long-term use of cardboard and has poor practicality.

[0004] An existing patent (publication number: CN215152766U) discloses a paperboard with wear and crack resistance, comprising an upper paperboard, a lower paperboard disposed on one side of the upper paperboard, and a first fiber reinforcement layer and a second fiber reinforcement layer sandwiched between the upper and lower paperboards, with the second fiber reinforcement layer disposed on both sides of the first fiber reinforcement layer. The first and second fiber reinforcement layers between the upper and lower paperboards enhance the toughness of the double-layer paperboard, improve its crack resistance, and the combined arrangement of the upper and lower paperboards strengthens the paperboard's overall strength, effectively preventing easy penetration and damage by external forces.

[0005] To address the aforementioned issues, existing patents propose solutions that enhance the toughness of double-layer cardboard and improve its crack resistance by using a first and second fiber reinforcement layer between the upper and lower cardboard layers. However, during use, due to the inherent material properties, the cardboard's flame retardancy is insufficient, thereby reducing its flame retardant performance. Summary of the Invention

[0006] The purpose of this invention is to provide a fiber paperboard with flame-retardant effect. By filling the inside of the paperboard with two sets of flame retardants, the flame retardants can decompose at high temperatures to produce a large amount of non-flammable gases such as water vapor and carbon dioxide. These gases form a protective layer on the surface of the paperboard, isolating it from air and heat, thereby inhibiting combustion and achieving the flame-retardant effect, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a fiber paperboard with flame-retardant effect, comprising a paperboard body, a positioning groove on the upper surface of the paperboard body, a flame-retardant mechanism for flame retardant paperboard inside the paperboard body, and a protective mechanism for protecting items on the inner side of the paperboard body.

[0008] The flame-retardant mechanism includes a positioning strip, which is fixed to the lower surface of the cardboard body. The positioning strip is inserted into the positioning slot. An installation cavity is provided inside the cardboard body. Several reinforcing cores are fixed to the inner wall of the installation cavity. Both ends of the reinforcing cores are filled with flame retardant.

[0009] Preferably, the left side of the cardboard body is provided with a wear-resistant outer layer.

[0010] Preferably, the outer wall of the wear-resistant outer layer has four symmetrical fixing holes, and a fixing rod is inserted into each of the four fixing holes.

[0011] Preferably, the end of the fixing rod is fixed with a waterproof plate that fits tightly against the outer surface of the wear-resistant outer layer.

[0012] Preferably, the protective mechanism includes a buffer inner plate, which is disposed inside the cardboard body.

[0013] Preferably, two connecting blocks are fixed on the left side of the inner buffer plate, and a limit block is fixed at the end of each of the two connecting blocks.

[0014] Preferably, one side of the limiting block is abutted against and connected to a buffer spring that is fixedly connected to the inner surface of the cardboard body.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Through the set flame-retardant mechanism, two sets of flame retardants are filled inside the cardboard body. The flame retardants can decompose at high temperature to produce a large amount of non-flammable gases such as water vapor and carbon dioxide. These gases form a protective layer on the surface of the cardboard, which isolates air and heat, thereby inhibiting combustion and achieving the effect of flame retardancy.

[0017] 2. Through the protective mechanism, when the internal items shake and collide with the inner wall of the carton, the inner buffer plate will drive the connecting block to move, causing the limit block to push the buffer spring to compress, thereby achieving the buffering effect and improving the protection of the items.

[0025] 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.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 A flame-retardant fiberboard includes a paperboard body 1, a positioning slot 2 on the upper surface of the paperboard body 1, a flame-retardant mechanism for flame retardant paperboard inside the paperboard body 1, and a protective mechanism for protecting items on the inner side of the paperboard body 1.

[0028] The flame-retardant mechanism includes a positioning strip 3, which is fixed to the lower surface of the cardboard body 1. The positioning strip 3 is inserted into the positioning slot 2. The cardboard body 1 has an installation cavity 31 inside. Several reinforcing cores 32 are fixed to the inner wall of the installation cavity 31. Both ends of the reinforcing cores 32 are filled with flame retardant 33. The left side of the cardboard body 1 has a wear-resistant outer layer 34. The outer wall of the wear-resistant outer layer 34 has four fixing holes 4 symmetrically opened. Fixing rods 5 are inserted into the four fixing holes 4. The ends of the fixing rods 5 are fixed with a waterproof plate 6 that is tightly attached to the outer surface of the wear-resistant outer layer 34.

[0029] By adopting the above technical solution, before using the flame-retardant fiberboard, the cardboard is first assembled, and the cardboard body 1 is spliced ​​into a carton. The positioning slot 2 set on the cardboard body 1, with the cooperation of the positioning strip 3, facilitates positioning and splicing. The items to be packaged are placed into the spliced ​​carton. The wear-resistant outer layer 34 set on the outer wall of the cardboard body 1 can enhance the wear resistance of the cardboard. The fixing rod 5 is aligned with the fixing hole 4 opened on the wear-resistant outer layer 34, and the waterproof plate 6 is pushed again to fix the waterproof plate 6 to the outer wall of the cardboard, so that the cardboard has a waterproof effect. The reinforcing inner core 32 set in the mounting cavity 31 can enhance the overall strength of the cardboard body 1 and improve the durability of the cardboard. The two sets of flame retardants 33 filled inside the cardboard body 1 can decompose at high temperature to produce a large amount of water vapor, carbon dioxide and other non-flammable gases. These gases form a protective layer on the surface of the cardboard, which isolates air and heat, thereby inhibiting combustion and achieving the flame-retardant effect.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the protective mechanism includes a buffer inner plate 7, which is placed inside the cardboard body 1. Two connecting blocks 71 are fixed on the left side of the buffer inner plate 7. Limiting blocks 72 are fixed at the ends of the two connecting blocks 71. A buffer spring 73, which is fixedly connected to the inner surface of the cardboard body 1, is abutted and connected to one side of the limiting block 72.

[0031] By adopting the above technical solution, when the internal items shake and collide with the inner wall of the carton, the buffer inner plate 7 inside the cardboard body 1 will drive the connecting block 71 to move, so that the limiting block 72 pushes the buffer spring 73 to compress, thereby achieving the buffering effect and improving the protection effect of the items.

[0032] Working principle: The wear-resistant outer layer 34 on the outer wall of the cardboard body 1 enhances the wear resistance of the cardboard. The fixing rod 5 is aligned with the fixing hole 4 on the wear-resistant outer layer 34, and the waterproof plate 6 is pushed again to fix the waterproof plate 6 to the outer wall of the cardboard, so that the cardboard has a waterproof effect. The reinforcing inner core 32 in the mounting cavity 31 enhances the overall strength of the cardboard body 1 and improves the durability of the cardboard. The two sets of flame retardants 33 filled inside the cardboard body 1 can decompose at high temperature to produce a large amount of water vapor, carbon dioxide and other non-flammable gases. These gases form a protective layer on the surface of the cardboard, which isolates air and heat, thereby inhibiting combustion and achieving the flame retardant effect. The buffer inner plate 7 inside the cardboard body 1 drives the connecting block 71 to move when the internal items shake and collide with the inner wall of the carton. This causes the limiting block 72 to push the buffer spring 73 to compress, thus achieving the buffering effect.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
