Problems solved by technology

[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. Poor, it's all the existing problems

Embodiment 1

[0034] A production method of an aluminum-plastic panel, the aluminum-plastic panel comprises an upper aluminum alloy layer, a middle layer and a lower aluminum alloy layer connected in sequence, the middle layer adopts a flame-retardant material PE plastic profile, and the upper aluminum alloy layer and the lower aluminum alloy layer The alloy layers are all sprayed with flame-retardant paint, and a filling ring groove is formed between the upper aluminum alloy layer and the lower aluminum alloy layer, which is arranged on the side of the middle layer, and 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 weak alkaline degreasing liquid, brush roller, a certain amount of neutral degreasing liquid, neutralization chamber, washing tank , forming tank, drying box and cooling fan;

Embodiment 2

[0053] This embodiment is basically the same as Example 1, the only difference being that the mass concentration of each composition of the alkaline solution in step B in the step (1) degreasing process is sodium carbonate 50-60g / L, sodium chromate 15 -20g / L and trisodium phosphate 1.5-2g / L, and in an environment of 92°C, the duration is between 8min-10min, so that an oxide film is formed on the surface of the aluminum sheet, and the alkaline oxidation solution according to the above ratio is used The film layer obtained in the method is soft, has poor corrosion resistance, high porosity, and good adsorption, which improves the adsorption effect during plastic coating and ensures a good spraying effect.

Embodiment 3

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

[0056] In the step (1) in the embodiment 1,2,3, the aluminum sheet obtained by the basic oxidation method is immersed in 20g / L of CrO 3 In the solution, passivation treatment at room temperature for 5-15 seconds, and then drying at a temperature lower than 50°C 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...
