Embodiment Construction

[0012] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings. Wherein, the same parts adopt the same reference numerals.

[0013] As mentioned in the background technology, red, orange, and yellow in visible light are long-wave light, and blue-blue-violet are short-wave light. The short-wave in visible light has certain damage to the glasses, especially the blue light can reach deep into the retina, which is especially harmful. In view of this, the present invention provides an anti-visible short-wave damage window film, which absorbs and blocks short-wave visible light, especially blue light, blue and purple light, through the cooperation of a double-layer base film that can prevent Short-wave visible light damages the window film.

[0014] Such as figure 1 As shown, it shows a schematic ...

Abstract

The invention discloses an anti-short-wave visible light damage window film, which sequentially comprises a composite refraction coating, an anti-blue light base film, a dyed adhesive layer, an anti-ultraviolet light base film, a pressure-sensitive adhesive layer and a release film from the outside to the inside. The present invention absorbs and blocks short-waves in visible light, especially blue light, cyan and violet light, through the cooperation of double-layered base films, so as to obtain a window film that can prevent short-wave damage of visible light. In addition, the present invention can also adjust the basic tone of the window film after absorbing blue-violet light through the dyed adhesive layer, making it as colorless and transparent as possible, so that the window film can be more easily and widely applied to various occasions.

Description

technical field [0001] The invention relates to the technical field of window films pasted on the window glass surfaces of vehicles or buildings, in particular to a window film capable of absorbing and blocking short waves in visible light, and in particular to a window film for preventing short wave damage of visible light. Background technique [0002] More than 99% of the solar radiation spectrum in the upper boundary of the earth's atmosphere is between 0.15 and 4.0 microns in wavelength. About 50% of the solar radiation energy is in the visible spectrum (wavelength 0.4-0.76 microns), 7% in the ultraviolet spectrum (wavelength < 0.4 microns), 43% in the infrared spectrum (wavelength > 0.76 microns), and the maximum energy is in the wavelength 0.475 micron. Since the wavelength of solar radiation is much smaller than that of ground and atmospheric radiation (about 3 to 120 microns), solar radiation is usually called short-wave radiation, and ground and atmospheric ...
