Abstract

The invention discloses frame sealing glue and a preparation method thereof, and relates to the field of displaying. Compared with existing frame sealing glue, the frame sealing glue is high in bonding strength, applied to a liquid crystal display panel with a narrow frame, and capable of improving the yield of a product with the narrow frame. The preparation method of the frame sealing glue includes the steps of compounding raw material, evenly stirring the compounded raw material under the temperature of 30 DEG C, mixing the prepared and stirred raw material at the temperature of 30 DEG C to 40 DEG C, removing bubbles contained in the raw material after mixing, testing viscosity, adjusting, filtering, and removing residues, wherein the composition and the proportion of the raw material used for preparing the frame sealing glue are as follows: 60-70% of low viscosity epoxy acrylic light-cured resin with the viscosity of 40-80 Pa.s, 1-2% of photoinitiator, 1-2% of coupling reagent, 5-15 % of conventional organic fillers, 10-20% of conventional inorganic fillers, and 5% of nanometer fillers.

Description

technical field

[0001] The invention relates to the display field, in particular to a frame sealant and a preparation method thereof. Background technique

[0002] Liquid crystal displays are now widely used in various display fields, such as homes, public places, office places and personal electronic related products. When making them, the array (Array) substrate and the color filter (Color Filter) substrate are manufactured separately, and then The array substrate and the color filter substrate are aligned and formed into a cell (Cell).

[0003] At present, in the box-making process, the rapid drop-injection box-making process (ODF process) is mostly used, and the sealing glue is coated on the color film substrate, and then the TFT substrate and the color film substrate are boxed together, and after a certain amount of UV irradiation, then Through the heating process, the sealing glue is cured, so that the TFT substrate and the color filter substrate are bonded together. ...
