Problems solved by technology

However, due to the poor continuous coatability of the ink, small light-transmitting spots are prone to appear. For this, the prior art uses multiple coats of ink to improve the shielding property.
[0005] However, the process of the above-mentioned method is complicated, and the combination between the ink layer and the ink layer, and between the ink layer and PET is usually poor. When it is used at a high temperature for a long time or in a position where electronic products need to be folded frequently, it is easy to cause the ink layer to fall off, and it is difficult to Thinning the product

Embodiment Construction

[0039] The present invention will be described in detail below in conjunction with the implementations shown in the drawings, but it should be noted that these implementations are not limitations of the present invention, and those of ordinary skill in the art based on the functions, methods, or structural changes made by these implementations Equivalent transformations or substitutions all fall within the protection scope of the present invention.

[0040] Such as figure 1 As shown, the aluminum foil Mylar tape of the present invention includes from top to bottom: a surface layer 10, an ink layer 20, a black PET layer 30, an acrylic adhesive layer 40, an aluminum foil layer 50, a conductive adhesive layer 60, and an isolation layer 70. Wherein, the total thickness of the surface layer 10 , the ink layer 20 , the black PET layer 30 , the acrylic adhesive layer 40 , the aluminum foil layer 50 and the conductive adhesive layer 60 is 40 μm˜100 μm.

Abstract

The invention provides an AlMylar adhesive tape and a preparation method thereof. The AlMylar adhesive tape comprises a surface layer, an ink layer, a black PET (polyethylene terephthalate) layer, an acrylic adhesive layer, an aluminum foil layer, a conductive adhering layer and an isolation layer from top to bottom, wherein the ink layer is prepared from the following components in parts by weight: 80 to 120 parts of ink, 30 to 80 parts of solvent, 2 to 5 parts of isocyanate type curing agent, and 0.5 to 2 parts of aids. The AlMylar adhesive tape has the advantages that the light shielding requirements of electronic products are met, and the thinning effect of the product is favorably realized; the technology is simple, and the coating amount and the coating frequency of the ink are reduced; the ink layer is firmly bonded with the black PET layer, the easiness in falling of the ink layer is avoided, and the problem of poor bonding force between the ink layer and the black PET layer in the existing multi-time coating technology is solved.

Description

technical field [0001] The invention relates to the technical field of adhesive tapes, in particular to an aluminum foil Mylar adhesive tape and a preparation method thereof. Background technique [0002] With the rapid development of electronic technology, computers and radio communications are widely used and densely configured, which provides convenience for people's lives. However, at the same time, such electronic products also produce a large amount of electromagnetic radiation during use, which has become an invisible "killer" that endangers human health. Long-term and excessive electromagnetic radiation will cause damage to human reproductive, nervous and immune systems, and at the same time it will form the main cause of skin diseases, cardiovascular diseases, diabetes, and cancer mutations. Electromagnetic wave radiation has been listed by the WHO as the fourth largest source of environmental pollution after water, air and noise. As people pay more and more atten...
