Description

Technical Field

[0001] The utility model relates to an aluminum foil, in particular to an explosion-proof aluminum foil with elastic buffering, belonging to the technical field of explosion-proof aluminum foils. Background Art

[0002] Explosion-proof aluminum foils are used in equipment such as oil tank trucks, storage oil tanks in gas stations, and oil pipelines to improve the safety of these equipment and reduce the occurrence probability of fire or explosion accidents. Existing explosion-proof aluminum foils are mostly made of a relatively thick single-layer aluminum foil for explosion protection. The outside of the single-layer aluminum foil is easily damaged by external impacts, resulting in the exposure of the internal fuel tank or oil pipeline. At the same time, the single-layer aluminum foil has poor elasticity and is easily broken into fragments when subjected to internal impacts, causing secondary damage to the vicinity.

[0003] Therefore, it is urgent to improve the explosion-proof aluminum foil with elastic buffering to solve the above existing problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an explosion-proof aluminum foil with elastic buffering. The explosion-proof layer is protected by an external elastic layer and arc-shaped layers. When subjected to external impacts, the convex blocks on the arc-shaped layers provide buffering. When subjected to internal impacts, multiple braided ropes cross to form a net to support the explosion-proof layer. When the internal impact is too large and the explosion-proof layer is damaged, the elastic layer pulls back the crack, reducing the crack of the internal explosion-proof layer and preventing fragments from flying out at the same time.

[0005] To achieve the above purpose, the main technical solutions adopted by the utility model include: two of the arc-shaped layers are respectively located on the upper and lower sides of the elastic layer. The elastic layer includes braided ropes and fixing blocks. The braided ropes all penetrate through the fixing blocks and are fixedly connected to the fixing blocks. The explosion-proof layer is located on one side of the elastic layer and is fixedly connected to the arc-shaped layers. The braided ropes include a coating layer and an internal elastic layer. The arc-shaped layers include a plurality of grooves and a plurality of convex blocks. The plurality of grooves correspond to the plurality of braided ropes, and the plurality of convex blocks are located between the plurality of grooves. The upper surface and the lower surface of the fixing blocks are fixedly connected to the intersection points of the plurality of grooves. A protective layer is provided on the outer surface of the outer arc-shaped layer.

[0006] Preferably, the braided ropes are arranged in a cross pattern, the fixing blocks are located at the intersections of the multiple braided ropes, and multiple equilateral triangles are formed after the braided ropes cross.

[0007] Preferably, the thickness of the fixing blocks is greater than the diameter of the braided ropes, and a plurality of ventilation slits are formed between the arc-shaped layers and the braided ropes.

[0008] Preferably, a heat-sealing layer is fixedly connected to the upper surface of the explosion-proof layer, and the heat-sealing layer is fixedly connected to the arc-shaped layer.

[0009] Preferably, the heat-sealing layer includes cloth and heat-sealing glue, and the heat-sealing glue covers both the upper and lower sides of the cloth.

[0010] Preferably, the covering layer is composed of multiple aluminum wires, and the inner elastic layer is composed of multiple glass fiber wires.

[0011] Preferably, the protective layer is a polyester-based TPU film.

[0012] The utility model has at least the following beneficial effects:

[0013] 1. The explosion-proof layer is protected by the external elastic layer and the arc surface layer. When subjected to external impact, the bumps on the arc surface layer provide buffering. When subjected to internal impact, multiple braided ropes cross to form a net to support the explosion-proof layer. When the internal impact is too large and the explosion-proof layer is damaged, the elastic layer pulls back the crack, reducing the crack of the internal explosion-proof layer and preventing fragments from flying out.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will describe the embodiments of the present application in detail in conjunction with the drawings and embodiments, so as to fully understand the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects and implement accordingly.

[0022] As Figures 1-5As shown in the figure, the explosion-proof aluminum foil with elastic buffer provided in this embodiment includes an explosion-proof layer 1, an elastic layer 2, and two arc-shaped layers 3. The two arc-shaped layers 3 are respectively located on the upper and lower sides of the elastic layer 2. The elastic layer 2 includes braided ropes 4 and fixing blocks 5. The braided ropes 4 are arranged in a cross pattern, and the fixing blocks 5 fix the braided ropes 4 at the intersections of multiple braided ropes 4, enabling multiple braided ropes 4 to bear force together. After the braided ropes 4 cross, a plurality of equilateral triangles are formed, making the overall structure stable. The explosion-proof layer 1 is located on one side of the elastic layer 2 and is fixedly connected to the arc-shaped layer 3. The braided rope 4 includes a coating layer 401 and an inner elastic layer 402. The coating layer 401 is composed of multiple aluminum wires, and the inner elastic layer 402 is composed of multiple glass fiber filaments. Multiple aluminum wires are woven on the outer layer of the glass fiber. Multiple glass fibers are twisted multiple times to form one, making the glass fiber filaments elastic. The arc-shaped layer 3 has multiple grooves 6 and multiple bumps 7. The multiple grooves 6 correspond to the multiple braided ropes 4, and the multiple bumps 7 are located between the multiple grooves 6. The upper surface and the lower surface of the fixing block 5 are fixedly connected to the intersection points of the multiple grooves 6. The explosion-proof layer 1 is made of 7075 aluminum. The single-layer explosion-proof layer 1 has an explosion-proof effect, and the external elastic layer 2 and arc-shaped layer 3 protect the explosion-proof layer 1. When subjected to external impact, the bumps 7 on the arc-shaped layer 3 provide buffering. When subjected to internal impact, multiple braided ropes 4 cross to form a net to provide support for the explosion-proof layer 1. When the internal impact is too large and causes the explosion-proof layer 1 to break, the elastic layer 2 pulls back the crack, reducing the crack of the internal explosion-proof layer 1 and preventing fragments from flying out. A protective layer 8 is provided on the outer surface of the outer arc-shaped layer 3. The protective layer 8 is a polyester-based TPU film, and the polyester-based TPU film has the effect of wear resistance and puncture resistance.

[0023] Further, as Figure 2 and Figure 3 shown in the figure, the thickness of the fixing block 5 is greater than the diameter of the braided rope 4. A plurality of ventilation slits 9 are formed between the arc-shaped layer 3 and the braided rope 4. When subjected to impact, the gas in the bump 7 quickly flows into other bumps 7 through the ventilation slits 9, enabling multiple bumps 7 to bear force together.

[0024] Among them, as Figure 3 shown in the figure, a heat-sealing layer 10 is fixedly connected to the upper surface of the explosion-proof layer 1. The heat-sealing layer 10 is fixedly connected to the arc-shaped layer 3. The heat-sealing layer 10 includes a cloth 12 and a heat-sealing adhesive 11. The heat-sealing adhesive 11 covers the upper and lower sides of the cloth 12. The explosion-proof layer 1 and the arc-shaped layer 3 are fixedly connected through the heat-sealing adhesive 11. When the explosion-proof layer 1 breaks, the explosion-proof layer 1 and the elastic layer 2 quickly separate at the break, preventing the impact force from being too concentrated locally in the elastic layer 2.

[0025] As Figures 1-5As shown in the figure, the principle of the explosion-proof aluminum foil with elastic buffer provided in this embodiment is as follows: The explosion-proof layer 1 is made of 7075 aluminum. The single-layer explosion-proof layer 1 has an explosion-proof effect. The external elastic layer 2 and the arc-shaped layer 3 protect the explosion-proof layer 1. The covering layer 401 is composed of multiple aluminum wires, and the inner elastic layer 402 is composed of multiple glass fiber wires. The multiple aluminum wires are woven outside the glass fiber. The multiple glass fiber wires are twisted multiple times to form a single one, making the glass fiber wires elastic. When subjected to external impact, the bumps 7 on the arc-shaped layer 3 provide buffering. When subjected to internal impact, the multiple braided ropes 4 cross to form a net to provide support for the explosion-proof layer 1. When the internal impact is too large and causes the explosion-proof layer 1 to break, the elastic layer 2 pulls back the crack, reducing the crack of the internal explosion-proof layer 1 and preventing fragments from flying out. The protective layer 8 is a polyester-based TPU film, which has the effect of wear resistance and puncture resistance. The explosion-proof layer 1 and the arc-shaped layer 3 are fixedly connected by a heat-sealing adhesive 11. When the explosion-proof layer 1 breaks, the explosion-proof layer 1 and the elastic layer 2 quickly separate at the break, preventing the impact force from being too concentrated locally on the elastic layer 2.
