Description

Technical Field

[0001] This utility model relates to the field of thin film technology, specifically to a four-sided shrinkage magnetron sputtering energy-saving base film. Background Technology

[0002] Traditional magnetron sputtered base films generally suffer from insufficient barrier properties, low mechanical strength, and high energy consumption. While multilayer composite structures can improve performance in existing technologies, poor interlayer bonding and uneven thickness distribution lead to unstable optical performance. Furthermore, nanoscale films are insufficient for the demands of millimeter-scale industrial applications. Therefore, there is an urgent need for a base film that combines high barrier properties, millimeter-scale thickness, and energy-saving characteristics. Summary of the Invention

[0003] The purpose of this invention is to provide a four-sided shrinkable magnetron sputtering energy-saving base film to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A four-sided shrinkable magnetron sputtering energy-saving base film is characterized by comprising a first composite layer structure, a second composite layer structure, and a third composite layer structure, wherein a first barrier layer is disposed between the first composite layer structure and the second composite layer structure, and a second barrier layer is disposed between the second composite layer structure and the third composite layer structure, wherein the first composite layer structure, the second composite layer structure, and the third composite layer structure all include a niobium oxide layer, a zinc aluminum oxide layer, and a silver alloy layer.

[0006] The present invention further provides that the thickness ratio of the first composite layer structure, the second composite layer structure, and the third composite layer structure is 1-1.5∶1-1.5∶1-1.5.

[0007] The present invention further provides that the thickness ratio of the barrier layer to the thickness of the first composite layer is 1-2:1-1.5.

[0008] In a further embodiment of this invention, the barrier layer is made of silicon dioxide.

[0009] The present invention further provides that the thickness ratio of the niobium oxide layer, the zinc-aluminum oxide layer, and the silver alloy layer is 1.33:1:1.

[0010] The present invention is further provided that the niobium oxide layer, zinc aluminum oxide layer, silver alloy layer and silicon dioxide are formed by magnetron sputtering.

[0011] The beneficial effects of this utility model are as follows: Through the three-layer composite structure design and the optimization of the barrier layer, it has the following effects: the niobium oxide layer improves hardness and corrosion resistance, the zinc aluminum oxide layer enhances conductivity, and the silver alloy layer optimizes light reflectivity; the barrier layer inhibits interlayer diffusion and ensures interface stability; the project adopts magnetron sputtering coating process for production, and the barrier layer protects the silver alloy layer to ensure that the reflectivity of infrared light will not decrease with the extension of use time, further extending the service life of the window film and providing a long-lasting high heat insulation effect.
