Embodiment
[0023] In the liquid crystal display panel, the sealant is mainly used to connect and seal the first substrate and the second substrate that are oppositely arranged, and form a liquid crystal cell with the first substrate and the second substrate to prevent water vapor from entering; at the same time, the sealant also It is used to support the first substrate and the second substrate, so that a gap is formed between the first substrate and the second substrate, and maintain a stable and reliable environment inside the box. Therefore, the strength and flexibility of the sealant are the key factors affecting the display performance of the LCD panel factor.
[0024] An embodiment of the present invention provides a frame sealant, such as figure 1 As shown, the frame sealant 10 includes: a resin 11, an epoxy oligomer (not shown in the figure), a curing agent (not shown in the figure) and a filler 12, wherein the frame sealant 10 also includes aramid nano fiber13.

Abstract
The invention discloses a frame-sealing adhesive and a liquid crystal display panel. The frame-sealing adhesive comprises resin, an epoxy oligomer, a curing agent, a filling agent and aramid nanofibers. According to the invention, the aramid nanofibers are added into the frame-sealing adhesive, and the aramid nanofibers and the resin form a three-dimensional network structure in the heating hardening process, so that the frame-sealing adhesive has high strength and high flexibility; and meanwhile, after the aramid nanofibers are added into the frame-sealing adhesive, the structure of the frame-sealing adhesive is more compact, water can be prevented from permeating, and the low-moisture permeability of the frame-sealing adhesive is improved.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a frame sealing glue and a liquid crystal display panel. Background technique [0002] With the development of liquid crystal display technology, the market has higher and higher requirements for the performance and process level of liquid crystal display screens, the most obvious of which is that the frame of the screen is getting narrower and narrower, and the technology of narrow frame has a great impact on the performance of the sealing glue (Seal). Higher requirements are put forward. Seal is an important material in Liquid Crystal Display Module (LCM). Its function is to encapsulate liquid crystal, prevent light leakage, and block external water and oxygen. It is not easy to crack, which ensures that the LCM has a certain ability to resist falling and impact during use. [0003] Generally, Seal is composed of resin, epoxy oligomer, heating hardener, silica, filler, and ad...
