Abstract

The invention discloses an electronic paper transparent plastic front panel and a preparation method thereof. The electronic paper transparent plastic front panel comprises an AG film, an ultravioletblocking adhesive layer and a water blocking film, the ultraviolet blocking adhesive layer is located between the AG film and the water blocking film, the ultraviolet blocking adhesive layer is a polyurethane adhesive layer, and the transmittance of the ultraviolet blocking adhesive layer at 380 nm is smaller than 6%; wherein the transmittance of the ultraviolet blocking glue layer at 280nm-370nmis less than 1%, and a ultraviolet blocking glue solution comprises the following components in parts by weight: polyurethane resin, 2-(5-chlorobenzotriazolyl)-6-tert-butyl p-cresol, 6-(2-benzotriazolyl)-4- tert-octyl-6-tert-butyl-4-methyl 2,2'-methylene bisphenol, a curing agent and a solvent. The manufactured front panel has good ultraviolet blocking performance, anti-dazzle performance and water blocking performance at the same time, can be better suitable for reading of a user, and meanwhile prolongs the service life of the front panel.

Description

technical field [0001] The invention belongs to the technical field of electronic paper, and in particular relates to a transparent plastic front panel of electronic paper and a preparation method thereof. Background technique [0002] In recent years, as lightness, flexibility, impact resistance, etc. are excellent, and the area can be easily increased, there is a demand for electronic paper from devices using glass substrates to devices using transparent plastic film front plates. Since ultraviolet rays and water vapor will hinder the display performance of electronic paper ink, the transparent plastic front panel is required to have ultraviolet blocking properties and water vapor blocking properties. In addition, in order to prevent glare from affecting the reading experience during the use of electronic paper, the transparent plastic front panel also needs to have anti-glare function. [0003] The existing ultraviolet blocking adhesive layer is acrylic adhesive layer wi...
