Description

Technical Field

[0001] This utility model relates to the technical field of stainless steel composite plates, specifically a high-strength stainless steel composite plate. Background Technology

[0002] Stainless steel composite sheet is a special type of sheet material that combines the properties of stainless steel and another metal to achieve resource conservation and cost reduction without compromising performance. These properties and wide range of applications make stainless steel composite sheet an indispensable material in many industrial sectors.

[0003] Existing stainless steel composite panels are mostly produced by combining stainless steel with another metal material to form a composite panel, which is widely used for building curtain wall installation. This ensures aesthetics and extends service life. However, most existing stainless steel composite panels are solid and have a relatively simple structure, making them heavy and difficult to install as curtain walls. Furthermore, their high production cost results in poor performance when used as curtain walls. Therefore, a high-strength stainless steel composite panel is proposed to solve the above-mentioned problems. Utility Model Content

Detailed Implementation

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0033] like Figures 1 to 5As shown in the figure, a high-strength stainless steel composite plate provided by this utility model embodiment includes a composite plate body 1. The composite plate body 1 includes an upper protective layer 11, a lower protective layer 12, and a support layer 13. The upper protective layer 11 and the lower protective layer 12 can protect the support layer 13, and the support layer 13 supports the upper protective layer 11 and the lower protective layer 12, thereby improving the overall structure of the entire composite plate body 1. The support layer 13 is located between the upper protective layer 11 and the lower protective layer 12. The upper protective layer 11 and the lower protective layer 12 also include a first stainless steel plate 14, a second stainless steel plate 15, and a sandwich steel plate 16. The sandwich steel plate 16 is located between the first stainless steel plate 14 and the second stainless steel plate 15. The composite panel 11 and the sandwich steel plate 16 are cold-rolled together. The upper and lower ends of the support layer 13 are respectively provided with a first insulation layer 17 and a second insulation layer 18. The support layer 13 is an aluminum alloy plate 19. By using the first stainless steel plate 14 and the second stainless steel plate 15, the appearance of the composite panel body 1 is ensured while preventing the outer surface of the composite panel body 1 from rusting. By using the sandwich steel plate 16, the strength of the upper protective layer 11 and the lower protective layer 12 is improved. With the use of the aluminum alloy plate 19, the center of the composite panel body 1 can be supported. The aluminum alloy plate 19 is lightweight, reducing the weight of the composite panel body 1. The lower end of one of the second stainless steel plates 15 is provided with a first adhesive layer 21, and the upper end of the other second stainless steel plate 15 is provided with a second adhesive layer 22. The first adhesive layer 21 is bonded to one of the second stainless steel plates 15 and the first insulation layer 17, respectively. The second adhesive layer 22 is bonded to the other second stainless steel plate 15 and the second insulation layer 18, respectively. The use of the first adhesive layer 21 and the second adhesive layer 22 ensures a tight bond between the two second stainless steel plates 15 and the first insulation layer 17 and the second insulation layer 18, guaranteeing stability. A third adhesive layer 31 is provided on the lower end face of the first insulation layer 17, and a fourth adhesive layer 32 is provided on the upper end face of the second insulation layer 18. The third adhesive layer 31 and the fourth adhesive layer 32 are bonded to the aluminum alloy plate 19. The use of the third adhesive layer 31 and the fourth adhesive layer 32 improves the adhesion between the first insulation layer 17, the second insulation layer 18, and the aluminum alloy plate 19. To ensure the overall structural stability of the composite panel, several evenly distributed through holes 41 are provided on the aluminum alloy plate 19. The inner diameter of the through holes 41 gradually decreases from the top and bottom ends towards the center. By using several through holes 41, the amount of aluminum alloy plate 19 material used can be reduced, thereby reducing the weight of the composite panel body 1. The decreasing inner diameter of the through holes 41 from the top and bottom ends towards the center can improve the supporting strength. The first stainless steel plate 14 and the second stainless steel plate 15 are both 304 stainless steel. 304 stainless steel has a variety of properties, including good corrosion resistance, excellent processing performance, hygiene and environmental protection, beautiful appearance, and good mechanical properties. It not only ensures the aesthetics of the composite panel body 1, but also has good corrosion resistance. The sandwich steel plate 16 is made of 201 stainless steel.201 stainless steel has a low nickel content, resulting in moderate strength that meets certain application requirements. Furthermore, it is relatively inexpensive. Positioning holes 51 are provided at each of the four corners of the composite plate body 1. These four positioning holes 51 allow for the fixing of the composite plate body 1, facilitating its installation and securement.

[0034] The working principle and usage process of this utility model are as follows: During use, the upper protective layer 11 and the lower protective layer 12 cooperate to protect the middle support layer 13. The aluminum alloy plate 19 can support the center position of the composite plate, improve the structural strength of the composite plate body 1, and, in conjunction with the use of two first stainless steel plates 14, can prevent the surface of the composite plate body 1 from rusting and improve the aesthetics of the composite plate body 1. The use of the sandwich steel plate 16 can enhance the strength of the upper protective layer 11 and the lower protective layer 12 and prevent the upper protective layer 11 and the lower protective layer 12 from denting or bending. The use of the first adhesive layer 21 and the second adhesive layer 22 can allow the two second stainless steel plates 15 to be bonded and fixed to the first insulation layer 17 and the second insulation layer 18 respectively. The use of the third adhesive layer 31 and the fourth adhesive layer 32 can allow the aluminum alloy plate 19 to be bonded and fixed to the first insulation layer 17 and the second insulation layer 18. The use of several through holes 41 can reduce the material used for the aluminum alloy plate 19 and ensure that the composite plate body 1 is sufficiently lightweight, thereby realizing the entire usage process of the high-strength stainless steel composite plate.
