Problems solved by technology
[0003] At present, the traditional low-e energy-saving window film has some shortcomings such as single color and poor heat insulation performance, and the golden low-e energy-saving window film with strong decorative effect is even rarer.
At present, most of the window films are heat-reflective coating window films with poor energy-saving performance, which have poor structural stability, poor heat insulation effect, and short service life, which is not conducive to wide-scale promotion of products.
[0004] In the industrial production of low-radiation and energy-saving window films, the magnetron window film needs to be coated and compounded in the later stage of production, which makes the window film inevitably contact with air, which causes its oxidation, and the temperature changes during transportation , will also accelerate the oxidation of the window film, directly affecting its service life

The invention discloses a gold low-radiation energy-saving window film and a preparation method thereof. The window film is gold in the sunshine, and a film layer structure of the gold window film sequentially comprises a flexible transparent PET base material layer, a first high-refractive-index layer, a first metal oxide layer, a first silver alloy layer, a first blocking layer, a second high-refractive-index layer, a second metal oxide layer, a second silver alloy layer, a second blocking layer and a third high-refractive-index layer from the inside to outside. The window film disclosed by the invention forms a refractive-index matching relationship with the three high-refractive-index layers through reflection of the double silver alloy layers for an infrared light, and moreover, the window film has a colour observed to be gold in the sunshine through matching of thickness parameters, and has a great visual effect. Meanwhile, the gold window film further has excellent light-transmitting, heat-isolating and oxidation-resistant performance, and is long in service and easy to produce.
Description
technical field [0001] The invention relates to a film attached to the window glass of automobiles, buildings, etc., in particular to a window film that is golden in sunlight, in particular to a golden low-radiation energy-saving window film and a preparation method thereof. Background technique [0002] The window glass of automobiles, buildings, etc. often needs to be attached with film, usually called window film, to provide functions such as heat insulation and UV protection. At the same time, the window film with excellent performance can also provide good visible light transmittance, which can be clearly observed from the inside of the window glass. Among them, the low-emission window film, also known as the Low-E window film, is formed by depositing a low-emission film layer on the surface of a flexible transparent substrate; With high reflectivity, it is a film product with the advantages of high light transmission and high heat insulation. [0003] At present, the...
