Embodiment Construction

[0036] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the present invention can be practiced.

[0037] 1. Experimental raw materials:

[0038] Diisocyanate reactants, trifunctional reactants (also known as moderately flexible reactants), acetone or butanone, bromophenol blue, di-n-butylamine, hydrochloric acid, toluene, isopropanol.

[0039] The above-mentioned diisocyanate reactants can be selected from hexamethylene diisocyanate (HDI), toluene diisocyanate (TDI) or diphenylmethane-4,4'-diisocyanate (MDI), such as choosing to use hexamethylene diisocyanate (HDI);

[0040] The above-mentioned trifunctional reactants (moderately flexible reactants) can be selected from polyether triols, polycaprolactone triols or polycarboxylic acid terpolymers, such as polyether triols;

[0041] The epoxy resin monomer can be epichlorohydrin or other aromatic epoxy resin monomers, preferably bisphenol A typ...

Abstract

The invention discloses sealant of a liquid crystal panel and a modification method thereof. The sealant comprises modified epoxy resin, wherein the modified epoxy resin is generated by crosslinking and solidifying an isocyanato-terminated trifunctional monomer and an epoxy monomer; the modified epoxy resin has multiple trident long-chain crosslinked structures, each trident long-chain crosslinked structure has three isocyanato groups to flexibly joint one or more molecular groups of the epoxy resin respectively; and the modified epoxy resin is capable of improving surface adhesive property and stress cracking resistant property on a glass substrate and can be effectively prevented from being miscible with a liquid crystal material so as to relatively reduce pollution on the liquid crystal material.

Description

technical field [0001] The present invention relates to a liquid crystal panel sealant and a modification method thereof, in particular to a liquid crystal panel sealant and a sealant for a liquid crystal panel which uses an isocyanate-terminated trifunctional monomer to modify an epoxy resin. its modification method. Background technique [0002] Liquid Crystal Displays (LCDs) have been widely used in various electronic products. Most of the LCDs are backlight LCDs, which are composed of a liquid crystal panel and a backlight module. Please refer to figure 1 As shown, the structure of an existing liquid crystal panel 10 generally includes: two transparent glass substrates 11, 12; a sealant 13 for sealing, coated between the two glass substrates 11, 12; and , a liquid crystal material 14 sealed in the space surrounded by the sealant 13 . In the assembly process of the liquid crystal panel 10, the liquid crystal material 14 should be sealed between the two glass substrates...
