Embodiment 1

[0034] like figure 1 As shown, a xenon lamp test polarizer includes a protective film 1, a polarizing original plate 2, a pressure-sensitive adhesive layer 3 and a release film 4 bonded together from top to bottom, and the dye-based polarizing original plate 2 consists of The first layer of cellulose triacetate film layer 2-1, the dye-based polarizer 2-2 and the second layer of cellulose triacetate film layer 2-3 bonded together from top to bottom in sequence.

[0035] Wherein, the first cellulose triacetate film layer 2-1 adopts a cellulose triacetate film layer with anti-ultraviolet performance, and the anti-ultraviolet performance means that the transmittance of the full light spectrum at 380nm is 0-5 %.

[0036] The dye-based polarizer 2-2 is formed by swelling, dipping, stretching, color correction and drying of polyvinyl alcohol film, and the dipping liquid is a dichroic dye liquid. The dye-based polarizer 2-2 is bonded with the upper and lower layers of cellulose tria...

Embodiment 2

[0057] A xenon lamp test polarizer, the structure of which is basically the same as that of Example 1, the difference lies in: the hue bs value of the dye-based polarizer original plate 2 is 3.

Embodiment 3

[0059] A xenon lamp test polarizer, the structure of which is basically the same as that of Example 1, the difference lies in: the hue bs value of the dye-based polarizer original plate 2 is -5.

Abstract

The invention discloses a polarizer resistant to a xenon lamp test. The polarizer comprises a protective film, a polarization original plate, a pressure-sensitive adhesive layer and a release film, the polarizer is characterized in that the polarization original plate is a dye type polarization original plate, the polarization original plate comprises a uvioresistant film layer, a dye type polarization element and a cellulose triacetate film layer which are sequentially glued together and a hue value of the dye type polarization original plate ranges from -5 to 5. The polarizer disclosed by the invention can be effectively improved in resistance to the xenon lamp test and avoids the yellowing phenomenon appearing after the xenon lamp test. The invention also provides a preparation method of the polarizer resistant to the xenon lamp test.

Description

technical field [0001] The invention relates to the technical field of polarizer preparation, in particular to a xenon lamp resistance test polarizer and a preparation method thereof. Background technique [0002] Polarizers are an essential part of liquid crystal displays. Common polarizers include iodine-based polarizers and dye-based polarizers. Among them, the iodine-based polarizer has poor heat resistance and moisture resistance, which cannot meet the application of the new generation of liquid crystal display technology in various occasions, especially the use of outdoor instruments and the automotive industry; while the dye-based polarizer has excellent moisture resistance. Good performance and heat resistance, which can well meet the needs of new trends. [0003] When dye-based polarizers are used in displays and instruments that need to work outdoors for a long time, such as instrument displays, rearview mirror displays, sunroofs, and heat insulation films in the ...
