Macro-molecular leakage-free self-adhering aluminum foil and manufacturing method thereof

The macro-molecular leakage-free self-adhering aluminum foil, wherein air gaps in one surface or two surfaces of the aluminum foil are filled with nano-aluminum to form a permeable air gap-free surface, the PET film is compounded with one surface of the aluminum foil using an adhesive, and the other surface of the aluminum foil is coated with a modified PE adhesive layer.

An air gap filling production line for a macro-molecular leakage-free self-adhering aluminum foil, comprising a PLC controller, wherein an aluminum foil air gap detection device, a nano-aluminum powder spraying device and a nano-aluminum powder rolling forming device are sequentially provided between an aluminum foil unreeling roll and an aluminum foil reeling roll;

• a photoelectric signal output end of the aluminum foil air gap detection device is connected to a signal input end of the PLC controller, one of signal output ends of the PLC controller is connected to a signal input end of the nano-aluminum powder spraying device, and the other signal output end of the PLC controller is connected to a signal input end of a servo motor;
• the servo motor drives the transmission of the aluminum foil reeling roll.

An aluminum foil air gap repair production line, wherein an electrostatic friction generator, a nano coating device and a nano-aluminum powder rolling forming device are sequentially provided between the aluminum foil unreeling roll and the aluminum foil reeling roll;

• each of the electrostatic friction generator, the nano coating device and the nano-aluminum powder rolling forming device is provided with an inlet and an outlet allowing the aluminum foil to enter and exit;
• after the aluminum foil is discharged from the aluminum foil reeling roll, the aluminum foil sequentially passes through the electrostatic friction generator, the nano coating device and the nano-aluminum powder grinding forming device, and the repaired aluminum foil is reeled by the aluminum foil reeling roll which is driven by a speed reduction motor to rotate.

A filling method for the aluminum foil air gap repair production line, wherein during working, a switch of the motor is started, the motor drives the aluminum foil reeling roll and the double-roll rolling roll in the nano-aluminum powder rolling forming device to rotate, and the aluminum foil enters the electrostatic friction generator from the aluminum foil unreeling roll under the traction of the aluminum foil reeling roll and is subject to forceful friction by the upper and lower pile pads in the electrostatic friction generator, such that the surface of the aluminum foil generates static;

• when the aluminum foil whose surface has static passes through the nano coating device, nano-aluminum powder in the nano coating device is adhered to the surface of the aluminum foil, and by means of the rolling of the double-roll rolling roll in the nano-aluminum powder rolling forming device, the nano-aluminum powder is then compacted by the double-roll rolling roll to well repair air gaps in the surface of the aluminum foil;
• excessive nano-aluminum powder on the surface of the aluminum foil is removed by the surface cleaning brush, and finally the aluminum foil is reeled by the aluminum foil reeling roll.
