[0034] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0035] Embodiment 1: Referring to the veneer stainless steel plate shown in 1, it comprises a substrate 1 and a veneer panel 2 covering the substrate 1. The substrate 1 is a stainless steel plate of the prior art, with a specification of 3000mm×1000mm×1.2mm. A mounting groove 11 with a width of 500mm, a length of 3000mm and a depth of 0.5mm is formed by milling in the center on the surface of the substrate 1 by means of the prior art.

[0036] The veneer panel 2 is an acetate board of the prior art, with a specification of 3000mm×500mm×0.5mm, for example, an acetate board with a tortoise shell decorative pattern or a marble decorative pattern. The veneer panel 2 with a certain thickness can achieve a three-dimensional and realistic decorative effect. The thickness of the veneer panel 2 is the same as the depth of the mounting groove 11, so after assembly, the veneer panel 2 is completely embedded in the mounting groove 11. Of course, when the thickness of the veneer panel 2 is greater than the depth of the mounting groove 11, the veneer panel 2 is partially exposed outside the mounting groove 11. The width of the veneer panel 2 allows a maximum deviation of positive 0.5mm. In this case, the width of the veneer panel 2 is 0.5mm larger than the width of the mounting groove 11.

[0037] During assembly, hot melt adhesive is applied on the back of the decorative panel 2, and the decorative panel 2 is placed in the installation groove 11. Then, hot pressing at 160°C / 0.8MPa is used to form a bonding layer of the adhesive to fix the back of the decorative panel and the bottom of the installation groove.

[0038] In the first aspect, the present embodiment uses a decorative panel 2 with a certain thickness, so that the decorative panel 2 can play a three-dimensional and realistic decorative effect. In the second aspect, the present embodiment uses the setting of the installation groove 11, and the width of the installation groove 11 is smaller than the width of the decorative panel 2, so that the decorative panel 2 is firmly embedded in the installation groove 11, and the auxiliary adhesive layer plays a role in enhancing the bonding strength between the two and avoiding the problem of the decorative layer 2 falling off. At the same time, as an additional advantage, because the combination of the decorative panel 2 and the substrate 1 often uses a hot pressing process, under the action of temperature and pressure, the decorative panel 2 softens to a certain extent, and the softened acetate board has a certain bonding force, so the side of the decorative panel 2 can form a bond with the groove wall of the installation groove 11, which improves the bonding strength between the decorative panel 2 and the substrate 1 and avoids the problem of the decorative panel 2 falling off during use.

[0039] As a preferred embodiment, a layer of steel plate 3 with a thickness of preferably 2.0 mm can be bonded on the back of the substrate 1 to improve the overall thickness and strength of the facing stainless steel plate. The steel plate 3 is a common steel plate, such as a carbon steel plate.

[0040] Example 2: Reference 2 and Figure 3 The veneer stainless steel plate shown in the figure comprises a substrate 1 and a veneer panel 2 covering the substrate 1, and a steel plate 3 with a thickness of 2.2 mm is bonded to the back of the substrate 1. The substrate 1 comprises a bottom plate 12, and a pair of surface plates 13 are bonded to the surface of the bottom plate 12 and the part close to the two side edges, and the opposite side edges of the pair of surface plates 13 and the exposed surface of the bottom plate 12 constitute a mounting groove 11.

[0041] The bottom plate 12 and the top plate 13 are both stainless steel plates of the prior art, with specifications of 3000mm×1000mm×0.8mm and 3000mm×250mm×0.5mm, respectively. After applying hot melt adhesive on the back of a pair of top plates 13 and the surface of the steel plate 3, the side edges of the top plates 13 are aligned with the side edges of the bottom plate 12 and placed on the surface of the bottom plate 12. The pair of top plates 13 are fixedly connected to the surface of the bottom plate 12 and the steel plate 3 is fixedly connected to the back of the floor 12 through a hot pressing process. Then, the opposite sides of the pair of top plates 13 and the exposed surface of the bottom plate 12 constitute the above-mentioned installation groove 11, and the thickness of the top plates 13 is the depth of the installation groove 11.

[0042] The veneer panel 2 is an acetate board of the prior art, for example, an acetate board with a tortoise shell decorative pattern or a marble decorative pattern. The veneer panel 2 has a specification of 3000 mm×500.3 mm×0.5 mm.

[0043] During assembly, hot melt adhesive is applied on the back of the decorative panel 2, and the decorative panel 2 is placed in the installation groove 11. Then, hot pressing at 160°C / 0.8MPa is used to form a bonding layer of the adhesive to fix the back of the decorative panel and the bottom of the installation groove.

[0044] Embodiment 3: Embodiment 3 differs from Embodiment 2 in that, referring to Figure 4 and Figure 5 As shown, there are several drawing grooves 14 on the exposed surface of the bottom plate 12. In other words, in the area on the surface of the bottom plate 12 that is not covered by the surface plate 13, several drawing grooves 14 are obtained by milling using the means of the prior art. Preferably, the drawing groove 14 is arranged along the length direction of the bottom plate 12 and penetrates the bottom plate 12. The drawing groove 14 can be an ordinary rectangular groove, but it is more preferred that the width of the opening of the drawing groove 14 is smaller than the width of its groove bottom. For example, the opening of the drawing groove 14 formed on the surface of the bottom plate 12 has a width of 0.5 mm, and the groove bottom of the drawing groove 14 has a width of 0.6 mm, so that the cross-section of the drawing groove 14 is trapezoidal.

[0045] The back of the decorative panel 2 has an integrally formed connection column 21 embedded in the wire drawing groove 14. In this embodiment, the connection strength between the decorative panel 2 and the base plate 12 can be improved by mechanical connection through the cooperation between the wire drawing groove 14 and the connection column 21.

[0046] Preferably, the size of the veneer panel 2 before assembly is 3000mm×500.5mm×0.55mm, hot melt adhesive is applied on the back of the veneer panel 2, the veneer panel 2 is placed in the installation groove 11, and then after thermal contact at 160°C for 15 minutes, a pressure of 0.8MPa is applied to the surface of the veneer panel 2, and the adhesive is formed into a bonding layer by hot pressing to fix the back of the veneer panel and the bottom of the installation groove. Under the action of temperature, the veneer panel 2 softens, and then under the action of pressure, part of the material on the back of the veneer panel 2 is squeezed into the wire drawing groove 14, and forms a connecting column 21 after cooling.

[0047] Those skilled in the art will appreciate that, depending on the hot pressing temperature and pressure, the formed connecting column 21 may completely fill the drawing groove 14 or may only partially fill the drawing groove 14. Figure 6 As shown, the formed connecting column 21 may completely fill the drawing groove 14. Figure 7 As shown, the formed connecting column 21 only partially fills the drawing groove 14. Figure 8 As shown, the formed connecting column 21 only partially fills the drawing groove 14, and the cross section of the end face of the connecting column 21 is an arc surface that is recovered inward. However, in any case, since the drawing groove 14 is a trapezoidal groove, it can play the role of mechanically connecting the decorative panel 2 and the base plate 12.

[0048] Embodiment 4: Embodiment 4 differs from Embodiment 2 in that the exposed surface of the base plate 12 has hairline texture. The hairline texture can be obtained by a hairline treatment process in the prior art, and the existence of the hairline texture can improve the bonding strength between the floor 12 and the decorative panel 2 to a certain extent. Of course, the exposed surface of the floor 12 can also play a similar role if it is a frosted surface.

[0049] The area where the surface plate 13 of the facing stainless steel plate of Examples 1 to 4 is located can be bent, and after bending, it can be used to make an elevator car.
