Abstract
The invention provides a polaroid and a preparation method and application thereof, wherein the preparation method comprises the following steps of firstly, sequentially connecting a triacetate fiber film A, a polaroid and a triacetate fiber film B to obtain a semi-finished polaroid; then coating methanol on the surface of the triacetate fiber film A of the semi-finished product of the polaroid, drying, coating hardening coating liquid again, and curing to obtain the polaroid; according to the preparation method, the hard coating does not need to be subjected to alkaline washing, the problems of falling, whitening and the like in the alkaline washing can be effectively avoided, the phenomena of poor appearance such as shrinkage, convection honeycombs and the like of the hard coating can be avoided, high adhesive force between the hard coating and a semi-finished product of the polaroid can be ensured, and the problems of block deformation, hard coating fracture and the like caused by adhesion phenomenon during unreeling and peeling can be avoided.
Description
Technical Field
The invention belongs to the technical field of polaroids, and particularly relates to a polaroid and a preparation method and application thereof.
Background
Polarizers are widely used as polarizing and analyzing elements in liquid crystal display devices. A polarizer in a liquid crystal display device has been formed by bonding a polarizer having a hydrophilic surface and a cellulose triacetate film (TAC) having high light transmittance, which are formed by polyvinyl alcohol (PVA) and iodine; the TAC plays the only role of protection in the polarizer, but the TAC is brittle and has the defects of high water absorption and environmental influence on surface characteristics, and the use performance of the polarizer is influenced by direct use. Therefore, in order to improve the product yield, a protection layer is generally applied on the TAC on the upper surface of the polarizer.
At present, the most common polarizer preparation technology is to coat a hard coating on TAC and then compound the TAC film and PVA into a polarizer, but because of poor adhesion of the two, chemical surface treatment (saponification treatment) is required to be performed with alkali before the TAC film and PVA are attached, and the hard coating in the saponification treatment process is inevitably immersed in an alkali solution, which affects the performance of the hard coating.
In order to avoid the above problems, a protective film may be coated on one side of the hard coat layer before the TAC alkali washing to eliminate adverse effects of the saponification reaction. JP10268133A discloses a method for producing a polarizer, which comprises the steps of firstly, arranging a protective layer on one side of a triacetyl cellulose film, and then, performing saponification treatment to obtain a triacetyl cellulose film with only one side being saponified; subsequently, the triacetyl cellulose film was bonded to both surfaces of the PVA so as to be in contact with the saponified surface. The hard coating film on the polarizer obtained in this way has better surface hydrophobicity. Although the method can avoid performance reduction caused by contacting the hard coating with alkaline solution to a certain extent, the production process is complex in the mode, and the edge parts of the two films are easy to permeate by the alkaline solution, so that the quality of the TAC is influenced.
On the other hand, a hard coat layer having alkali resistance may be provided on TAC. JP2015101109 discloses a hard coat layer having a surface with adhesiveness to a high adhesive after saponification treatment without using a protective film on the surface, wherein the hard coat layer has a water contact angle of 70 ° or less on the surface, and the water contact angle of the hard coat layer surface does not decrease even after saponification treatment. CN101790695a discloses a hard coat film with excellent soap resistance and wear resistance, which contains inorganic particles of different particle sizes, and the distribution of organic particles of different particle sizes in the hard coat layer is different. When the hard coat film is immersed in an alkaline solution, the inorganic fine particles present on the contact surface of the hard coat layer on the opposite side to the substrate film side and in the vicinity of the contact surface are not eluted or detached in the alkaline solution. However, the method still has the problem that the hard coating layer shrinks to cause the TAC to warp, and the production cost of the cured resin composition is high, so that the cured resin composition is not suitable for industrial use; in addition, because the TAC manufacturers have different processes, the produced film materials have different surface properties, and during the process of coating the hard coating film, the hard coating film often has poor appearance phenomena such as shrinkage cavity, convection honeycomb and the like due to uneven surface tension of the film substrate or different surface tension at a certain position, thereby seriously affecting the use of the polarizer.
Therefore, the development of a preparation method of the polarizer can ensure that the hard coating does not need to be subjected to alkaline washing liquid, so that the problems of falling off, whitening and the like of the hard coating in the alkaline washing liquid can be effectively avoided, the high adhesive force of the hard coating and TAC can be ensured, and the polarizer with excellent appearance is finally obtained.
