preparation example Construction

[0060] Correspondingly, the embodiment of the present application provides the preparation method of the frame sealant in the above embodiment of the application. The preparation method process flow of the sealing glue of the embodiment of the present application is as follows: Figure 5 shown, including the following steps:

[0061] Step S01: pre-dispersing the conductive fibers and the components contained in the frame sealing glue solution to obtain a mixture;

[0062] Step S02: Kneading the mixture to obtain a frame sealant.

[0063] Among them, the pre-dispersion treatment of the conductive fiber and the sealing glue in step S01 is to make the components mix uniformly. Therefore, as long as the mixing method can realize the uniform mixing of the components, it is within the scope disclosed in the specification of this application, such as In the embodiment, the temperature of the pre-dispersion treatment is 20°C-30°C, and the stirring time is 2h-4h. The temperature of ...

Embodiment 1

[0073] This embodiment provides a frame sealing glue and a preparation method thereof. The sealant of this embodiment includes the following components by weight percentage:

[0074] 20% epoxy resin, 73.75% acrylic resin, 0.75% photoinitiator, 5% thermosetting agent, and 0.5% carbon nanofiber.

[0075] Among them, the epoxy resin is bisphenol A epoxy resin, the acrylic resin is methacrylic resin, the photoinitiator is α,α-diethoxyacetophenone, the thermal curing agent is hexamethylenediamine, and the carbon nanofibers are helical The average diameter of the three-dimensional helical structure is 380nm, the average pitch is 100nm, the diameter of the carbon nanofiber is 100nm, the carbon nanofiber is graphitized (the graphitization rate is 65%), and the surface of the carbon nanofiber is modified by KH550. Example The viscosity of the frame sealant is 240 mPa·s.

[0076] The method for preparing the frame sealant comprises the following steps:

[0077] S1. Mix the HCNFs-KH55...

Embodiment 2

[0081] This embodiment provides a frame sealing glue and a preparation method thereof. Compared with Example 1, the sealing glue of this example is different in that the surface modification treatment of HCNFs does not use KH550.

[0082] The preparation method of the frame sealant is prepared according to the preparation method of the frame sealant in Example 1.

Abstract

The invention discloses frame sealing glue, a preparation method thereof and a display panel. The frame sealing glue comprises a frame sealing glue solution and conductive fibers dispersed in the frame sealing glue solution, and the conductive fibers are in a three-dimensional spiral shape. The frame sealing glue has excellent conductivity, high packaging quality, and excellent toughness and packaging bonding strength after being cured, and the separation resistance of two substrates of the box is improved. The preparation method of the frame sealing glue can ensure that the prepared frame sealing glue is stable in performance and high in efficiency. The display panel contains the frame sealing glue, and is stable in display and long in service life.

Description

technical field [0001] The application belongs to the technical field of display consumables, and in particular relates to a frame sealing glue, a preparation method thereof, and a display panel. Background technique [0002] In the manufacturing process of the thin film transistor liquid crystal display, the color filter substrate and the array substrate need to be bonded to each other, and the bonding material is the frame sealing compound. At present, the box-making process mostly adopts the rapid drip filling method (OneDropFilling, referred to as ODF). The curing of the frame sealing adhesive composition is realized through ultraviolet light irradiation and heating. [0003] The frame sealant composition plays the role of bonding the array substrate and the color filter substrate, and is used to seal the liquid crystal, so the frame sealant composition is a key material in the manufacturing process of the liquid crystal panel box. For twisted nematic (Twisted Nematic,...
