The ultra-violet light curing adhesive comprises following characteristics: 1 not needing mix; 2 rapid curing at indoor temperature, and controlling the curing speed; 3 suiting for supermatic flow operation; 4 excellent moisture-proof, low and high temperature impact property resistance, and long life; 5 100% solid coating, no environmental contamination. The UV curing adhesive possesses the advantages of short curing adhesive, strong adhesive force, heat resistance and moisture-proof, so it is used in LCD rim.
Description
Technical field
The present invention relates to a kind of preparation method of bonding agent, particularly be applied to the preparation method of ultraviolet cured adhesive of flat-panel display device (OLED and LCD display).
Background technology
The tradition adhesive often solidifies the bonding agent that contains one or more solvents by being heating and curing or adding curing agent. Ultraviolet photo-curing cementing agent is generally by photocuring prepolymer (25-90wt%), monomer (15-60 %), and light trigger (1-3%) and other additives consist of, and sometimes also cooperate light trigger to improve curing efficiency with sensitizer. This adhesive is rapidly simple curing under ultraviolet source irradiation.
At present, what domestic use was more is the epoxy resin cure glue that adopts the method for ionic polymerization curing, this curing glue easily causes display sealing pollution, and hardening time long (need 24 hours under the room temperature, and need about 4 hours 80 ℃ of curing). can't realize continuous productive process.
Shenzhen Tianma Microelectronics Co. is the preparation method who discloses a kind of ultraviolet light solid adhesives with liquid crystal sealling among the CN1049370 in China Patent Publication No., adopt main gel, curing agent, diluent and auxiliary agent are formulated by a certain percentage, its main gel adopts epoxy resin, and adds curing agent, coupling diluent and auxiliary agent and make. After 2 minutes, light trigger decomposes the generation free radical makes its polymerizing curable to main gel, and makes it change network structure into by linear structure at UV-irradiation. But above-mentioned patent exists solidification intensity poor, UV-irradiation was for up to 2 minutes during curing, be not suitable for the automation continuous productive process, in addition high temperature resistant, the high humility performance is not good, and binder component is to the pollution problem of liquid crystal filling mouth, and has no the report that it is used for the flat-panel monitor sealing.
Ocean Paint Inst., Ministry of Chemical Industry is to disclose a kind of curable adhesive among the CN1199075 in China Patent Publication No., when optic-solidified adhesive is used for the sealing of liquid crystal display device do, requires all curable adhesives all will stand following durability experiment:
(1) high temperature durability test: 80 ℃ * 400Hr;
(2) hot and humid endurancing: 80 ℃ * 90%RH * 400Hr;
(3) cold cycling endurancing :-40 ℃-80 ℃, 30 times
They think that existing ultraviolet photo-curing cementing agent can't satisfy above-mentioned requirements.
Ultraviolet photo-curing cementing agent is at optics, and such as optical fiber, the application on optical lens etc. bonding is more, in recent years extensive application also arranged at communication information on the assembling of electronic device.
Flat panel Display Technique-the liquid crystal display (LCD) of tool development prospect is just experiencing developing rapidly, becomes market focus. Because the excellent properties of ultraviolet light adhesive promotes and has supported the development of flat-panel monitor, because liquid crystal display and display of organic electroluminescence based on glass structure, use ultraviolet light polymerization processing bonding agent more suitable in manufacturing process. The ultraviolet light bonding agent becomes a pith supporting New flat panel display spare technique, support new production process. For example in the manufacturing process of liquid crystal display, there are seven kinds of arts demands to use ultraviolet cured adhesive, that is:
1. light million assembly contrapositions are temporary fixed
2. mainboard sealing
3. port sealing
4. the whole pole of metal pin is bonding
5. flexible whole pole sealing
6. bare chip mounts, and dystopy and film are bonding in the same way, and FCOG lid coating.
Summary of the invention
The invention provides a kind of preparation method of ultraviolet cured adhesive, overcome in the existing technique and be not suitable for the automation continuous productive process, otherwise address high temperature resistant, the anti-high humidity of existing UV glue, the poor problem of resistance to low temperature, and binder component is to the pollution problem of liquid crystal filling mouth, can be widely used in the OLED display of flat-panel monitor-particularly encapsulation, liquid crystal display (LCD) the sealing of liquid crystal filling mouth and pin is bonding and the techniques such as encapsulation of OLED display.
Technical solution of the present invention is: the flat-panel display device preparation method of ultraviolet cured adhesive, by main gel, to strengthen glue, reactive diluent, organo-silicon coupling agent, catalyst, stabilizing agent, light trigger formulated, described main gel adopts tetraglycidel ether epoxy resin and acrylic or methacrylic acid by 1～10: 1 quality compares proportioning, in container, add successively tetraglycidel ether epoxy resin, catalyst, polyether-type bisphenol-A, stabilizing agent and acrylic or methacrylic acid, 100～195 ℃ of reactions 2-16 hour, decompression is found time, and cooling is filtered and obtained the bisphenol-a epoxy acrylate prepolymer; Described enhancing glue adopts 663 epoxy resin and acrylic or methacrylic acid by 2～15: 1 quality compares proportioning, in container, add successively 663 epoxy resin, catalyst, stabilizing agent and acrylic or methacrylic acid, under 80～180 ℃ of temperature, reacted 1～1.5 hour, decompression is found time, and cooling is filtered and obtained the polyether-type epoxy acrylic ester prepolymer; Then main gel and strengthen glue by main gel: enhancing glue=2～5: 1 mass ratio is added in the reactor, under 50～90 ℃, insulated and stirred adds organo-silicon coupling agent, light trigger, stabilizing agent, reactive diluent again, reacted 2～3 hours, and filtered to get finished product.
Ultraviolet light of the present invention (UV) cured adhesive has following characteristics:
1. single-component system need not to be mixed;
2. room temperature fast-curing can be controlled at several seconds to tens minutes hardening time, and the thermo-sensitive material use is convenient in cold curing. Curing rate can be controlled in addition;
3. be fit to increasingly automated continuous productive process;
4. have the characteristics such as excellent anti-high humility, high-and low-temperature resistance impact property, thereby guaranteed the long-life of flat-panel monitor.
5.100% solid cladding, solvent-free, can not cause environmental pollution, can reduce fire hazard simultaneously;
In addition, have short, the advantages such as adhesion is strong, heat-resisting, moisture-proof hardening time because UV solidifies glue, promoted the use of at present on the edge banding frame of processing procedure before the LCD.
