[0039] like Figure 1 , Figure 4 and Figure 5 As shown, a method for manufacturing a plastic mobile phone frame is provided in the embodiment, which can be used to manufacture a plastic mobile phone frame.

[0040] In some embodiments, the method for manufacturing a plastic mobile phone frame may include:

[0041] S100, an aluminum powder layer is made on one side of the base film.

[0042] In some embodiments, the base film may be an adhesive tape with an adhesive layer attached to one side of the surface. In the embodiments, aluminum powder may be sprayed on the side of the base film away from the adhesive layer in an environment below 100° C. The diameter of the aluminum powder may be 0.1 mm-0.2 mm, thereby forming an aluminum powder layer on one side of the base film. The thickness of the aluminum powder layer may be set to 0.3 mm-0.4 mm.

[0043] In the embodiment, aluminum powder is sprayed in an environment below 100° C., which can reduce oxidation of the aluminum powder and prevent deformation of the base film due to heat, thereby ensuring the flatness of the base film.

[0044] S200, the base film is pasted to the inner wall of the mold, and the aluminum powder layer is facing the inner cavity of the mold, and plastic is poured into the mold to form the frame body 110 and the connector 120 to obtain an intermediate product, wherein an aluminum-plastic interlaced layer 210 is formed on the side of the intermediate product facing the base film.

[0045] In some embodiments, the adhesive layer of the base film can be pasted to the inner wall of the mold, and the side of the base film attached with the aluminum powder layer is facing the inner cavity side of the mold. Among them, the diameter of the aluminum powder in the aluminum powder layer is 0.1mm-0.2mm, and there will be gaps between adjacent aluminum powders. Thus, in the process of pouring plastic, part of the plastic will be filled in the gap between adjacent aluminum powders, and an aluminum-plastic staggered layer 210 with a thickness of 0.3mm-0.4mm will be formed. Correspondingly, the aluminum powder can penetrate into the edge position of the frame body 110 away from the side of the connector 120. In addition, the frame body 110 and the connector 120 can be integrally formed, that is, an intermediate product is obtained, and the sealing performance of the plastic mobile phone frame in use is improved. After the pouring is completed, the intermediate product can be cured and demoulded so that the cured intermediate product can be taken out from the mold. It is understandable that when the intermediate product is taken out of the mold, the tape can be taken out together with the intermediate product and attached to the side of the intermediate product where the aluminum-plastic staggered layer 210 is provided.

[0046] S300, tearing off the base film and polishing the surface of the intermediate product.

[0047] In an embodiment, the tape on the intermediate product can be torn off, and the surface of the intermediate product can be polished by a polishing machine, which can include polishing the side of the intermediate product provided with the aluminum-plastic interlaced layer 210 to remove dirt and aluminum oxide on the surface of the aluminum-plastic interlaced layer 210, and to ensure that the surface roughness of the intermediate product meets the processing requirements of the plastic mobile phone frame.

[0048] S400 , coating an aluminum nitride-zirconium nitride composite layer 220 on the aluminum-plastic interlaced layer 210 .

[0049] In some embodiments, step S400 may be completed in a coating device. The coating device may include a vacuum furnace and a power supply, and a workpiece rack for placing the intermediate product may be provided in the vacuum furnace.

[0050] Combined with Figure 2 In some embodiments, step S400 may include:

[0051] S410, connect the positive electrode of the power supply to the workpiece rack where the intermediate product is placed, connect the negative electrode of the power supply to the target material, the target material includes aluminum nitride, zirconium nitride and aluminum, set the voltage of the power supply to 800V-1000V, control the temperature in the vacuum furnace at 70℃-80℃, and control the vacuum degree in the vacuum furnace at 0.1Pa-1Pa.

[0052] In some embodiments, the mass ratio of each component in the target material can be set to 47%-53% aluminum nitride, 27%-33% zirconium nitride, and 17%-23% aluminum. For example, in some embodiments, the mass ratio of each component in the target material can be set to 47% aluminum nitride, 31% zirconium nitride, and 22% aluminum. Alternatively, the mass ratio of each component in the target material can be set to 50% aluminum nitride, 30% zirconium nitride, and 20% aluminum.

[0053] S420 , starting the power supply, performing vapor deposition for 20 minutes to 30 minutes, and obtaining the aluminum nitride-zirconium nitride composite layer 220 on the aluminum-plastic interlaced layer 210 .

[0054] Because aluminum nitride and zirconium nitride are not conductive, in the embodiment of the present application, adding aluminum to the target material can make the target material conductive. Thus, under the action of high voltage, the target material (cathode) will undergo aluminum ion sputtering due to the glow effect, and aluminum nitride and zirconium nitride can be evaporated and deposited on the intermediate product. Specifically, aluminum nitride and zirconium nitride can be deposited on the surface of the aluminum-plastic interlaced layer 210, and form an aluminum nitride-zirconium nitride composite layer 220 on the surface of the aluminum-plastic interlaced layer 210. In the coating process, because aluminum ions are positively charged and have the same electrical properties as the workpiece frame, aluminum ions will repel the workpiece frame and will not be deposited on the intermediate product.

[0055] In some embodiments, a 2 μm-3 μm thick aluminum nitride-zirconium nitride composite layer 220 may be plated on the surface of the aluminum-plastic interlaced layer 210 .

[0056] S500 , plating a titanium nitride-zirconium nitride composite layer 230 on a side of the aluminum nitride-zirconium nitride composite layer 220 away from the aluminum-plastic interlaced layer 210 .

[0057] In an embodiment, step S500 may also be completed in a coating device.

[0058] Combined with Figure 3 In some embodiments, step S500 may include:

[0059] S510, connect the positive electrode of the power supply to the workpiece rack where the intermediate product is placed, connect the negative electrode of the power supply to the target material, the target material includes titanium nitride, zirconium nitride and titanium, set the voltage of the power supply to 800V-1000V, control the temperature in the vacuum furnace at 70℃-80℃, and control the vacuum degree in the vacuum furnace at 0.1Pa-1Pa.

[0060] In some embodiments, the mass ratio of each component in the target material can be set to 67%-73% titanium nitride, 17%-23% zirconium nitride and 7%-13% titanium. For example, in some embodiments, the mass ratio of each component in the target material can be set to 73% titanium nitride, 18% zirconium nitride and 9% titanium. Alternatively, the mass ratio of each component in the target material can be set to 70% titanium nitride, 20% zirconium nitride and 10% titanium.

[0061] In the embodiment, the vacuum degree, temperature, power connection mode and power parameter settings during the process of plating the aluminum nitride-zirconium nitride composite layer 220 may be consistent with those during the process of plating the aluminum nitride-zirconium nitride composite layer 220 .

[0062] S520 , starting the power supply and performing evaporation for 50 minutes to 60 minutes to obtain a titanium nitride-zirconium nitride composite layer 230 on the side of the aluminum nitride-zirconium nitride composite layer 220 away from the aluminum-plastic interlaced layer 210 .

[0063] Under the action of high voltage, titanium nitride and zirconium nitride can be evaporated and deposited on the aluminum nitride-zirconium nitride composite layer 220 to form the aluminum nitride-zirconium nitride composite layer 220. Since titanium nitride has weak conductivity, in the embodiment of the present application, titanium is added to the target material to improve the conductivity of the target material, thereby improving the evaporation rate of the aluminum nitride-zirconium nitride composite layer 220. In some embodiments, the thickness of the aluminum nitride-zirconium nitride composite layer 220 can be set to 5μm-6μm.

[0064] Accordingly, the aluminum-plastic interlaced layer 210, the aluminum nitride-zirconium nitride composite layer 220 and the titanium nitride-zirconium nitride composite layer 230 can be used as the strengthening film 200 on one side of the frame body 110, which can have good wear resistance.

[0065] The plastic mobile phone frame produced by the plastic mobile phone frame production method provided by the present application may include the following advantages:

[0066] (1) By replacing the traditional aluminum-based mobile phone frame with plastic, the weight of the mobile phone frame can be further reduced, which is conducive to the lightweight design of electronic products.

[0067] (2) The frame body 110 and the connecting piece 120 are integrally formed by plastic injection molding, so that they can have higher sealing performance during use.

[0068] (3) The frame body 110 is insulated and the strengthening film 200 has very weak conductivity. Thus, the plastic mobile phone frame has good shielding performance, and the shielding effect is much better than the electroplating layer in traditional technology (because the electroplating layer is conductive and has poor shielding performance).

[0069] (4) In the aluminum-plastic interlaced layer 210 of the strengthening film 200, since the aluminum powder and the plastic are arranged in an interlaced manner, the aluminum powder can penetrate into the internal structure of the frame body 110, thereby enabling the aluminum-plastic interlaced layer 210 to have good bonding performance with the frame body 110. In addition, in the aluminum nitride-zirconium nitride composite layer 220, the aluminum nitride has an affinity with the aluminum powder, thereby enabling the aluminum nitride-zirconium nitride composite layer 220 to have good bonding strength with the aluminum-plastic interlaced layer 210. In addition, the titanium nitride-zirconium nitride composite layer 230 and the aluminum nitride-zirconium nitride composite layer 220 contain the same component zirconium nitride, and accordingly, the titanium nitride-zirconium nitride composite layer 230 and the aluminum nitride-zirconium nitride composite layer 220 can have good bonding strength. Thus, the strengthening film 200 in the plastic mobile phone frame of the present application can have good bonding strength with the frame body 110 as a whole, reducing the risk of delamination of the strengthening film 200.

[0070] (5) The hardness of the titanium nitride-zirconium nitride composite layer 230 of the outermost layer of the strengthening film 200 is above Hv1300, which can have very high wear resistance, so that the strengthening film 200 as a whole can have high wear resistance. In addition, the hardness of the aluminum nitride-zirconium nitride composite layer 220 is also above Hv800. From the inner layer to the outer layer of the plastic mobile phone frame, the plastic, aluminum-plastic staggered layer 210, aluminum nitride-zirconium nitride composite layer 220, and titanium nitride-zirconium nitride composite layer 230 increase in sequence, forming a hardness gradient. The inner layer can support the hardness of the outer layer, making the strengthening layer very wear-resistant.

[0071] like Figure 4 and Figure 5 As shown, a plastic mobile phone frame is also provided in the embodiment, which can be made by the plastic mobile phone frame manufacturing method provided in the embodiment. Wherein, the plastic mobile phone frame may include a frame body 110 and a connector 120. Wherein, the frame body 110 may be arranged around the peripheral side of the connector 120, and the frame body 110 and the connector 120 may be integrally injection molded. In addition, a strengthening film 200 may be provided on the side of the frame body 110 away from the connector 120, and the strengthening film 200 may include an aluminum-plastic interlaced layer 210, an aluminum nitride-zirconium nitride composite layer 220 and a titanium nitride-zirconium nitride composite layer 230 arranged in sequence, wherein the aluminum-plastic interlaced layer 210 may be an integral structure with the frame body 110, that is, the aluminum-plastic interlaced layer 210 may be fused to the edge position of one side of the frame body 110 away from the connector 120.
