Abstract

The invention discloses an adhesive for an iodine polarizer, a preparation method of the adhesive and the iodine polarizer. The adhesive is prepared from the following components in percentage by weight: 1.9-7 percent of an adhesive raw material, 90-97 percent of pure water, 0.2-0.5 percent of a crosslinking agent, 0.1-3.5 percent of EXP, 0.2-0.5 percent of ethylene glycol and 0.1-1 percent of glyoxal. With adoption of the adhesive, the purpose that the iodine polarizer is durable in the performance is achieved. After the adhesive is adhered to a PVA film, in the drying process, iodine ions in the PVA film can be better fixed and kept in an ordered chain state under the condition of 95 DEG C*500H and high temperature and high humidity of 65 DEG C*95 percent*1000H, so that the variation of the optical stability of the polarizer is no larger than 5 percent after and before a test under the conditions, the application range of the corresponding iodine polarizer is expanded, and the optical performance of an electronic product which applies the iodine polarizer is also improved.

Description

technical field [0001] The invention relates to the technical field of polarizer preparation, in particular to an adhesive for an iodine-based polarizer, a preparation method thereof, and an iodine-based polarizer. Background technique [0002] At present, the durability test performance of optical products for general-purpose iodine-based polarizers can only be achieved at dry temperature: 80°C*500H, high temperature and high humidity: 60°C*90%*500H, and the application range of iodine-based polarizers with this capability is relatively narrow , which can only be used on daily ordinary consumer products. [0003] However, with the increasing popularity of electronic products, polarizers used in mobile phones and car displays generally require dry temperature: 90°C*500H, high temperature and high humidity: 65°C*95%*500H, and now large Only dye-based polarizers meet the requirements, but it is difficult to achieve an optical transmittance of more than 42% and a degree of pol...
