Example Embodiment

[0033] Example 1

[0034] A method for producing aluminum-plastic panels. The aluminum-plastic panels include an upper aluminum alloy layer, a middle layer, and a lower aluminum alloy layer that are sequentially connected. The middle layer uses a flame-retardant material PE plastic profile, and the upper aluminum alloy layer and the lower aluminum alloy layer The alloy layers are sprayed with flame-retardant coatings. A filling ring groove arranged on the peripheral side of the intermediate layer is formed between the upper aluminum alloy layer and the lower aluminum alloy layer. The filling ring groove is filled with thermosetting resin. The production process includes the following steps: ( 1) Degreasing process: A. Preparation: aluminum sheet to be processed, spray chamber, degreasing spray pump, a certain amount of weakly alkaline degreasing fluid, brush roller, a certain amount of neutral degreasing fluid, neutralization chamber, water washing tank , Formation tank, drying b...

Example Embodiment

[0052] Example 2

[0053] This embodiment is basically the same as embodiment 1, the only difference is that the mass concentration of each composition of the alkaline solution in step B in step (1) degreasing process is 50-60g / L sodium carbonate and 15% sodium chromate. -20g / L and trisodium phosphate 1.5-2g / L, and at 92℃, the duration is between 8min-10min, so that an oxide film is formed on the surface of the aluminum sheet, using the alkaline oxidizing solution according to the above ratio The film obtained in the process is softer, poorer in corrosion resistance, higher in porosity, and good in adsorption, which improves the adsorption effect during plastic coating and ensures a good spray effect.

Example Embodiment

[0054] Example 3

[0055] This embodiment is basically the same as embodiment 1, the only difference is that the mass concentration of each composition of the alkaline solution in step B in step (1) degreasing process is 40-50g / L sodium carbonate and 10% sodium chromate. -20g / L and sodium silicate 0.6-1g / L, and in an environment of 98℃, the duration is between 8min-10min, so that an oxide film is formed on the surface of the aluminum sheet, in the alkaline oxidizing solution of the above ratio The obtained film has a higher hardness, and the relative adsorption effect will be worse.

[0056] In the step (1) of Examples 1, 2, and 3, the aluminum flakes obtained by alkaline oxidation were immersed in 20g / L CrO 3 In the solution, passivation treatment at room temperature for 5 to 15 seconds, and then drying at a temperature below 50 ℃, can improve the effect of corrosion resistance and ensure good practicability.

Abstract

The invention discloses a production method of an aluminum-plastic plate. The aluminum-plastic plate produced by the method has the effects of being good in corrosion resistance effect and plastic coating effect, and high in tensile strength. The aluminum-plastic plate is characterized by comprising an upper aluminum alloy layer, a middle layer and a lower aluminum alloy layer which are sequentially connected with one another, wherein the middle layer is prepared from flame-retardant material polyethylene (PE) plastic profiles; the upper aluminum alloy layer and the lower aluminum alloy layer are respectively sprayed with a flame-retardant coating; a filling ring groove is formed at the peripheral side of the middle layer and is positioned between the upper aluminum alloy layer and the lower aluminum alloy layer; the filling ring groove is internally filled with thermosetting resin. The production process comprises the following steps: (1) a degreasing process; (2) coating process; (3) compounding process; (4) strengthening process. The production method of the aluminum-plastic plate is suitable for the technical field of aluminum-plastic plate production.

Description

technical field [0001] The invention relates to a production method of an aluminum-plastic panel. Background technique [0002] The unique performance of the aluminum-plastic composite panel itself determines its wide range of uses: it can be used for building exterior walls, curtain wall panels, renovation of old buildings, interior wall and ceiling decoration, advertising signs, display stands, purification and dust prevention project. It belongs to a new type of building decoration material. [0003] The traditional production method for producing aluminum-plastic panels has cumbersome steps, and the produced aluminum-plastic panels have a poor oxidation effect on the aluminum panels, which affects the plastic coating effect, and the tensile strength of the composite aluminum panels and PE panels is relatively low. Bad, it's all the current problems. Contents of the invention [0004] In view of the deficiencies in the prior art, the object of the present invention i...
