Description

Technical Field

[0001] The present invention relates to the technical field of composite steel plates, and particularly to a composite steel plate with impact resistance and shock absorption functions. Background Art

[0002] A composite steel plate is a steel plate formed by combining two or more different materials through a specific process. It usually consists of a base layer and a cladding layer. The base layer provides strength and rigidity, while the cladding layer endows special properties. It has significant economic and performance advantages and is widely used in many industries such as petrochemical, offshore engineering, and power industries.

[0003] Although traditional composite steel plates have a certain strength, their shock absorption effect is generally poor, and it is difficult to meet the dual requirements of impact resistance and shock absorption simultaneously. In addition, most of the shock absorption designs in the existing technology adopt external shock absorption devices (such as springs, dampers, etc.), and there is a lack of effective synergy between the impact-resistant layer and the shock absorption layer, resulting in poor overall performance of the material. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the present invention provides a composite steel plate with impact resistance and shock absorption functions, which solves the technical problems that the composite steel plates in the existing technology are difficult to meet the dual requirements of impact resistance and shock absorption simultaneously and have poor overall performance, and has the advantages of enabling the composite steel plate to have excellent shock absorption effect and impact resistance performance at the same time.

[0005] To solve the above technical problems, the present invention provides the following technical solutions: A composite steel plate with impact resistance and shock absorption functions, including an alloy steel substrate. A shock absorption composite mechanism is arranged between the two alloy steel substrates, and an impact-resistant buffer mechanism is arranged between the shock absorption composite mechanism and the alloy steel substrate. A surface protection mechanism is arranged on the surface of the alloy steel substrate. The shock absorption composite mechanism can effectively improve the shock absorption performance of the composite steel plate, the impact-resistant buffer mechanism can improve the toughness of the composite steel plate, and the surface protection mechanism can effectively improve the scratch resistance of the composite steel plate. The shock absorption composite mechanism includes a sensing functional layer. Honeycomb structure layers are symmetrically arranged on both sides of the sensing functional layer. A number of honeycomb holes are formed inside the honeycomb structure layer, and a polymer foam is filled in the honeycomb holes. By filling the polymer foam in the honeycomb holes, the energy of vibration can be absorbed through the compression and rebound of the pore structure, thereby improving the shock absorption ability of the composite steel plate.

[0006] Preferably, the sensing functional layer is made of a piezoelectric material and is used to monitor the stress, strain, and damage conditions of the composite steel plate. When the composite steel plate is extruded by an external force, the sensing functional layer will monitor the damage suffered by the steel plate, thereby preventing the composite steel plate from being severely damaged.

[0007] Preferably, a viscoelastic polymer layer is provided on the outside of the ceramic coating. The viscoelastic polymer in the composite steel plate can improve the damping performance of the material, absorb and consume vibration energy, and thus reduce the response of the structure when subjected to vibration or impact.

[0008] Preferably, the impact-resistant buffer mechanism includes a memory alloy layer, a corrugated structure layer is arranged between the memory alloy layer and the viscoelastic polymer layer, and glass fiber is arranged on the side of the corrugated structure layer facing the alloy steel substrate. The glass fiber can effectively improve the tensile, compressive and bending resistance of the composite steel plate, thereby making the composite steel plate more stable and reliable when subjected to external loads.

[0009] Preferably, the memory alloy layer is adhered and fixed on the alloy steel substrate. When the alloy steel substrate is subjected to a severe impact, the memory alloy layer can recover to its original shape in a relatively short time after being deformed, thereby effectively improving the impact resistance of the composite steel plate.

[0010] Preferably, ceramic particles are provided on the side of the corrugated structure layer facing the shock-absorbing composite mechanism, which can effectively improve the hardness and wear resistance of the composite steel plate.

[0011] Preferably, the surface protection mechanism includes a surface texture opened on the alloy steel substrate, and plastic gaskets are respectively arranged at the four corners on the outside of the alloy steel substrate. When the composite steel plates are stacked, the presence of the plastic gaskets (fixed on the alloy steel substrate by gluing and can be scraped off with a knife when in use) can create a certain gap between two adjacent steel plates, thereby facilitating the staff to take them.

[0012] Preferably, the surface textures are provided in a plurality of groups at equal intervals, and the surface textures are polished by a grinding wheel, which can effectively improve the aesthetics and scratch resistance of the composite steel plate.

[0013] By means of the above technical solution, the present invention provides a composite steel plate with impact resistance and shock absorption functions, which has at least the following beneficial effects:

[0014] 1. The present invention provides a shock-absorbing composite structure and utilizes the cooperation between the viscoelastic polymer layer and the honeycomb structure layer to absorb and consume vibration energy step by step, thereby reducing the response of the composite steel plate when subjected to vibration or impact, and can greatly improve the shock-absorbing performance of the composite steel plate.

[0015] 2. The present invention provides a shock-absorbing composite structure and utilizes the cooperation between the ceramic coating and the viscoelastic polymer layer to provide certain protection for the weak honeycomb structure layer and the sensing function layer when the composite steel plate is subjected to high-speed impact, thereby ensuring that the honeycomb structure layer and the sensing function layer can function normally.

[0016] 3. By providing an impact-resistant buffer mechanism, and through the interaction between the shape memory alloy layer and the corrugated structure layer, the present invention can always maintain the overall integrity of the structure when subjected to explosion shock, avoid local fracture, effectively improve the tensile and bending resistance of the composite steel plate, so that the composite steel plate not only has a shock absorption effect but also excellent impact resistance;

[0017] 4. By providing an impact-resistant buffer mechanism and adopting an integral pressing method, the shock-absorbing layer can quickly absorb and consume vibrations, and the impact-resistant layer can enhance the overall strength and tensile properties of the structure. The two can have an effective synergistic effect, greatly improving the overall performance of the composite steel plate and also facilitating lightweight applications.

[0018] 5. By providing a surface protection mechanism, and through the interaction between the surface texture and the plastic gasket, the present invention can not only improve the aesthetics and scratch resistance of the composite steel plate, but also facilitate the handling and transfer of the composite steel plate by the staff during stacking and storage.

DETAILED DESCRIPTION OF THE INVENTION

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment 1

[0027] Although traditional composite steel plates have a certain strength, their shock absorption effects are generally poor, and it is difficult to simultaneously meet the dual requirements of impact resistance and shock absorption. In addition, most of the shock absorption designs in the prior art use external shock absorption devices (such as springs, dampers, etc.), and there is a lack of effective synergy between the impact-resistant layer and the shock absorption layer, resulting in poor overall performance of the material. To solve this technical defect in the prior art, as Figure 1 and Figure 3 shown, this embodiment proposes a composite steel plate with impact resistance and shock absorption functions, which can gradually absorb and consume vibration energy, thereby reducing the response of the composite steel plate when it is vibrated or impacted. The composite steel plate includes a alloy steel substrate 1, a shock absorption composite mechanism 2 is arranged between two alloy steel substrates 1, an impact-resistant buffer mechanism 3 is arranged between the shock absorption composite mechanism 2 and the alloy steel substrate 1, and a surface protection mechanism 4 is arranged on the surface of the alloy steel substrate 1. The shock absorption composite mechanism 2 can effectively improve the shock absorption performance of the composite steel plate, the impact-resistant buffer mechanism 3 can improve the toughness of the composite steel plate, and the surface protection mechanism 4 can effectively improve the scratch resistance of the composite steel plate.

[0028] Specifically, the shock absorption composite mechanism 2 includes a sensing functional layer 201, which is made of piezoelectric material and is used to monitor the stress, strain and damage conditions of the composite steel plate. When the composite steel plate is externally squeezed, the sensing functional layer 201 will monitor the damage suffered by the steel plate, thereby preventing the composite steel plate from being severely damaged. Honeycomb structure layers 202 are symmetrically arranged on both sides of the sensing functional layer 201. A number of honeycomb holes 203 are formed inside the honeycomb structure layer 202, and a polymer foam 204 is filled inside the honeycomb holes 203. A ceramic coating 205 is arranged outside the honeycomb structure layer 202. Filling the polymer foam 204 in the honeycomb holes 203 can absorb the vibration energy through the compression and rebound of the pore structure, thereby improving the shock absorption ability of the composite steel plate. A viscoelastic polymer layer 206 is arranged outside the ceramic coating 205. The viscoelastic polymer can improve the damping performance of the material in the composite steel plate, and can absorb and consume the vibration energy, thereby reducing the response of the structure when it is vibrated or impacted.

[0029] According to the above content, when the composite steel plate is in a continuous vibration condition, first of all, the outer viscoelastic polymer layer 206 will initially absorb and consume vibration energy, which can effectively reduce the response of the composite steel plate when subjected to vibration or impact.

[0030] Next, the honeycomb structure layer 202 and the polymer foam 204 will absorb a large amount of vibration energy through the compression and rebound of the pore structure, thus greatly improving the shock absorption ability of the composite steel plate.

[0031] Moreover, by setting the ceramic coating 205 between the viscoelastic polymer layer 206 and the honeycomb structure layer 202, when the composite steel plate is impacted by a sharp object, it can provide certain protection for the honeycomb structure layer 202 and the sensing function layer 201, and improve the strength of the shock absorption composite mechanism 2.

[0032] In this embodiment, by setting the shock absorption composite mechanism 2 and utilizing the mutual cooperation between the viscoelastic polymer layer 206 and the honeycomb structure layer 202, the vibration energy can be absorbed and consumed step by step, thereby reducing the response of the composite steel plate when subjected to vibration or impact, and can greatly improve the shock absorption performance of the composite steel plate; moreover, in this embodiment, by setting the shock absorption composite mechanism 2 and utilizing the mutual cooperation between the ceramic coating 205 and the viscoelastic polymer layer 206, when the composite steel plate is impacted at high speed, it can provide certain protection for the honeycomb structure layer 202 and the sensing function layer 201 with weak structures, so as to ensure that the honeycomb structure layer 202 and the sensing function layer 201 can function normally.

[0033] Embodiment Two

[0034] In order to prevent the composite steel plate from breaking during the explosion impact and improve the anti-impact performance of the steel plate, on the basis of Embodiment One, as Figure 1 and Figure 2 shown, this embodiment sets an anti-impact buffer mechanism 3. Specifically, the anti-impact buffer mechanism 3 includes a shape memory alloy layer 301, and the shape memory alloy layer 301 is fixedly pasted on the alloy steel substrate 1. When the alloy steel substrate 1 is subjected to a violent impact, the shape memory alloy layer 301 can return to its original state in a short time after deformation, which can effectively improve the anti-impact performance of the composite steel plate. There is a corrugated structure layer 302 between the shape memory alloy layer 301 and the viscoelastic polymer layer 206. On the side of the corrugated structure layer 302 facing the alloy steel substrate 1, there is a glass fiber 303. The glass fiber 303 can effectively improve the tensile, compressive and bending resistance of the composite steel plate, so that the composite steel plate is more stable and reliable when bearing external loads. On the side of the corrugated structure layer 302 facing the shock absorption composite mechanism 2, there are ceramic particles 304, which can effectively improve the hardness and wear resistance of the composite steel plate.

[0035] As can be seen from the above, when the surface of the composite steel plate is subjected to an explosion shock or a sharp impact, even if the alloy steel substrate 1 is severely damaged, the shape memory alloy layer 301 can recover itself within a certain period of time, so as to continue to protect the inner structure and effectively prevent local fracture from occurring.

[0036] Moreover, a glass fiber 303 is filled on the side of the shape memory alloy layer 301 away from the alloy steel substrate 1, which can effectively improve the tensile, compressive and bending resistance of the composite steel plate, so that the composite steel plate is more stable and reliable when bearing an external load.

[0037] In this embodiment, by providing the impact-resistant buffer mechanism 3 and utilizing the mutual cooperation between the shape memory alloy layer 301 and the corrugated structure layer 302, the overall integrity of the structure can be always maintained when subjected to an explosion shock, local fracture can be avoided, and the tensile and bending resistance of the composite steel plate can be effectively improved. Thus, while having a shock-absorbing effect, the composite steel plate also has excellent impact resistance; moreover, in this embodiment, by providing the impact-resistant buffer mechanism 3 and adopting the overall pressing method, the shock-absorbing layer can quickly absorb and consume vibrations, and the impact-resistant layer can enhance the overall strength and tensile performance of the structure. The two can have an effective synergistic effect, greatly improving the overall performance of the composite steel plate and being conducive to lightweight applications at the same time.

[0038] Embodiment Three

[0039] In order to improve the scratch resistance of the composite steel plate, on the basis of the above embodiment, as Figure 1 and Figure 4 shown, this embodiment provides a surface protection mechanism 4. Specifically, the surface protection mechanism 4 includes surface textures 401 formed on the alloy steel substrate 1. Several groups of surface textures 401 are arranged at equal intervals and are formed by grinding with a grinding wheel, which can effectively improve the aesthetics and scratch resistance of the composite steel plate. Plastic gaskets 402 are respectively arranged at the four corners on the outside of the alloy steel substrate 1. When the composite steel plates are stacked and placed, the presence of the plastic gaskets 402 (fixed on the alloy steel substrate 1 by pasting and can be scraped off with a tool during use) can create a certain gap between adjacent two steel plates, thus facilitating the staff to take them.

[0040] In this embodiment, by providing the surface protection mechanism 4 and utilizing the mutual cooperation between the surface textures 401 and the plastic gaskets 402, the aesthetics and scratch resistance of the composite steel plate can be improved, and it is also convenient for the staff to take and transfer the composite steel plates during the stacking and storage process.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
