Problems solved by technology

What needs to be improved is: in the production process of general aluminum foil, due to the lack of purity of the aluminum ingot or impurities, the surface gloss of the roll and other factors, the rolled aluminum foil contains defects such as micropores, which directly lead to the wrapped cable communication. Signal attenuation, return loss increase

Embodiment 1

[0010] Embodiment 1: with reference to attached figure 1 and figure 2 . A polymer non-leakage self-adhesive aluminum foil, the PET film 1 is compounded with an adhesive 2 and an aluminum foil 3 on one side, and a modified PE adhesive layer 4 is coated on the other side of the aluminum foil 3. The surface of the aluminum foil 3 is a surface without air gaps. The air gaps on one or both sides of the aluminum foil 3 are filled with nano-aluminum. The air gap refers to the tiny holes and gaps, that is, the tiny through holes and gaps caused by impurities and the roll itself during the aluminum foil rolling process are filled with nano-aluminum, so that the compactness of the aluminum foil has been further improved.

[0011] Its aluminum foil surface air gap filling production line includes PLC controller 06, aluminum foil air gap detection device 07, nano-aluminum spraying device 05 and nano-aluminum rolling forming device 03; The photoelectric signal output terminal of the g...

Embodiment 2

[0013] Example 2: On the basis of Example 1, a method for preparing a polymer non-leaking self-adhesive aluminum foil, 1） One side or two sides of the aluminum foil 3 are respectively filled with nano-aluminum of the same property, so that there is no air gap on the aluminum foil surface; 2） Then the PET film 1 is compounded on one side of the aluminum foil 3 with an adhesive 2; 3） Apply the modified PE glue on the non-composite surface of the aluminum foil 3 and dry it to obtain a modified PE film.

Abstract

The invention relates to macro-molecular leakage-free self-adhering aluminum foil which is good in folding resistance and fatigue resistance, high in strength, good in shielding performance and free of return loss and meanwhile has high reliability and self-adhering strength, and a manufacturing method. A PET film and one side of the aluminum foil are composited through an adhering agent, and the other side of the aluminum foil is coated with a modified PE glue layer. The macro-molecular leakage-free self-adhering aluminum foil has the advantages that the aluminum foil is resistant to folding and fatigue and high in strength which is several times that of the prior art; the wrapping self-adhering performance is good, and stripping strength formed after adhesion is several times that of the prior art; air gaps on the surface of the aluminum foil are filled with same-attribute nano aluminum, the compactness of the aluminum foil is greatly improved, the purpose of manufacturing the macro-molecular leakage-free self-adhering aluminum foil through low-grade aluminum foil is achieved, and therefore the requirement for the rolling precision of the aluminum foil is greatly lowered, and the manufacturing cost of the aluminum foil is reduced; insulating strength is high, the shielding effect is good, the return loss phenomenon is avoided, and the tensile strength is good.

Description

technical field [0001] The invention relates to a polymer non-leakage self-adhesive aluminum foil with good folding resistance and fatigue resistance, high strength, good shielding, no return loss, and high reliability self-adhesive strength and a production method thereof. It belongs to the field of communication auxiliary materials manufacturing. Background technique [0002] All the prior patents of the applicant CN201489850U, titled "high-strength double-sided self-adhesive aluminum foil", include aluminum foil, and are characterized in that: there is a layer of adhesive adhesive layer between the two sides of the aluminum foil and the PET film, and the PET film (1) side There is a self-adhesive membrane on it. What needs to be improved is: in the production process of general aluminum foil, due to the lack of purity of the aluminum ingot or impurities, the surface gloss of the roll and other factors, the rolled aluminum foil contains defects such as micropores, and the...
