Example Embodiment

[0037] The embodiment of the present invention provides a method for preparing a thermal curing agent, such as figure 1 As shown, the preparation method includes:

[0038] S101. Mix 3,5-dimethylaniline with epoxy resin.

[0039] The mixing ratio of 3,5-dimethylaniline and epoxy resin can be based on actual needs in industrial production, and is not limited in the embodiments of the present invention. However, according to the reaction principle that the two are undergoing a compound reaction, it is preferable in the embodiment of the present invention to mix 3,5-dimethylaniline with an epoxy resin in a molar ratio of 2:1 to make the reaction complete. So as not to waste raw materials.

[0040] Wherein, the above-mentioned epoxy resin may be a bisphenol A type epoxy resin with an epoxy value of 0.51.

[0041] S102. Stir the mixed 3,5-dimethylaniline and epoxy resin within a preset temperature range to cause the two to undergo a chemical reaction to generate a thermal curing agent, the...

Abstract

The embodiment of the invention provides a heat curing agent and a preparation method of the heat curing agent, a frame sealing adhesive, a display panel and a display device, relating to the field of display technology, aiming at reducing the pollution of the heat curing agent for liquid crystal in the frame sealing adhesive in a box technology, and improving the picture quality of a liquid crystal display (LCD) device. The preparation method of the heat curing agent comprises the steps of: mixing 3, 5-dimethylaniline and epoxy resin; and leading the mixed 3, 5-dimethylaniline and the epoxy resin to be subjected to combination reaction within the preset temperature range to obtain the heat curing agent. The invention is used for manufacturing the display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a thermosetting agent and a preparation method thereof, a frame sealant, a display panel, and a display device. Background technique [0002] At present, the ODF (One Drop Filling, liquid crystal dripping) process is mostly used in the box alignment process of the liquid crystal display panel, which specifically includes: dropping the liquid crystal on the array substrate, coating the frame sealant on the edge of the color filter substrate, and then, the color filter The film substrate and the array substrate are boxed to form a liquid crystal display panel, and the boxed liquid crystal display panel is irradiated with a certain amount of ultraviolet (Ultraviolet, UV) light, and then heated in a heating furnace to complete the curing of the sealing glue. [0003] The above-mentioned frame sealant has two functions: 1. to bond the array substrate and the color film substrate; 2. ...
