Problems solved by technology

[0004] However, the existing aluminum foil Mylar tape is prone to denaturation of the aluminum foil Mylar tape itself due to changes in temperature, humidity, etc. during use due to its production process and irregular materials, or due to excessive stretching. The fracture phenomenon caused by it, thus losing its use effect, and in the process of use, the aluminum foil and the polyester tape are prone to separation

Description

technical field [0001] The invention relates to the technical field of aluminum foil Mylar tape, in particular to an aluminum foil Mylar tape and a preparation method thereof. Background technique [0002] Aluminum foil Mylar is a new type of material that is gradually replacing traditional light-shielding materials. Aluminum foil Mylar is made of metal aluminum foil, glued on the back and polyester tape (generally PET, PP, etc.) , Mobile phones, computers, PDAs, PDPs, LED displays, notebook computers, copiers and other electronic products where electromagnetic shielding is required, which can eliminate electromagnetic interference, isolate electromagnetic waves from harming the human body, and prevent interference voltage and current from affecting product functions. [0003] Aluminum foil Mylar tape is made of aluminum foil and coated with acrylic or rubber pressure-sensitive adhesive. It adopts high-quality pressure-sensitive adhesive, which has good viscosity, strong ad...
