Embodiment Construction

[0017] The technical route is as follows:

[0018] Preparation of organic silicon modified epoxy resin matrix material:

[0019] Dissolve 7 grams each of silicone and epoxy resin with a weight ratio of 1:1 in 10 milliliters of xylene and cyclohexanone solvents, respectively, and stir with electromagnetic force at a temperature of 50°C and a stirring time of 4 After hours, the above solution was mixed and added to a 100 ml three-necked round-bottom flask, stirred by electromagnetic force, and then gradually dropped with a separatory funnel as the temperature changed to gradually add 0.01 mol of dibutyltin dilaurate catalyst, and finally the temperature was controlled at 136℃ After reacting for 10 hours, the light yellow transparent solution is obtained after the reflux reaction is completed, and the solvent is removed by vacuum distillation to obtain the silicone modified epoxy resin matrix glue material, which is a viscous light yellow transparent colloidal material.

Abstract

A composited binder material for packaging a electroluminescent device comprises 65.0-75.0% of organic silicon / epoxy resin matrix, 0.3-4.6% of ferroferric oxide fiber material, 2.0% of tetraethoxysilanecross-linking agent, 18.0-29.5% of the mixture of polyvinyl alcohol and polyethylene, and the balance of the assistant and a phthalic acid ester plasticizer, wherein the ratio of length to diameter of the fiber material is 4-6.

Description

Technical field [0001] The present invention relates to a packaging material for electroluminescent elements. More specifically, the packaging method of the present invention adopts a packaging method that has good bonding performance and can improve the defects such as brittleness and cracking caused by the stress of the bonding material. Adhesive material for connection. Background technique [0002] Organic electroluminescent device (OELD) is a new type of flat display device newly developed at present. It has low turn-on and drive voltage, and can be driven by DC voltage. It can be matched with large-scale integrated circuits, and it is easy to achieve full color and light emission. High brightness (> 105cd / m2), high quantum luminous efficiency (2.01m / w) and other advantages, but the service life of the OELD device cannot meet the application requirements. One of the technical difficulties that needs to be solved is the packaging materials and packaging technology of the d...
