Title:
HIGH-MOLECULAR LEAKAGE-FREE SELF-ADHERING ALUMINUM FOIL AND PREPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/115165
Kind Code:
A1
Abstract:
A high-molecular leakage-free self-adhering aluminum foil and a preparation method. One surface of a first-layer aluminum foil and one surface of a second-layer aluminum foil are compounded by using a PET film, and the other surface of each of the first-layer aluminum foil and the second-layer aluminum foil is coated with a PET adhesive layer; or air gaps of one surface or two surfaces of the aluminum foil (33) are filled with nano-aluminum to form a non-air-permeable air gap surface. The PET film (31) and one surface of the aluminum foil (33) are compounded by using an adhesive (32), and the other surface of the aluminum foil (33) is coated with a PE adhesive layer (34). The high-molecular leakage-free self-adhering aluminum foil has the advantages: firstly, the aluminum foil is resistant to folding and fatigue and high in strength that is several times that provided by a technology in the background; secondly, the wrapping self-adhering performance is good, and the stripping strength formed after adhesion is several times that provided by the technology in the background; thirdly, air gaps on the surface of the aluminum foil are filled with nano aluminum having a same attribute, the compactness of the aluminum foil is greatly improved, and the objective of preparing the high-molecular leakage-free self-adhering aluminum foil by using low-grade aluminum foil is achieved, thereby greatly lowering the requirements for the rolling precision of the aluminum foil, and reducing the manufacturing costs of the aluminum foil; and fourthly, the insulation strength is high, the shielding effect is good, the return loss phenomenon is avoided, and the tensile strength is good.
