Abstract
This invention relates to a UV-curing adhesive for binding the metal pins of liquid crystal displays. The adhesive comprises: prepolymer 30-80 wt. %, active monomer 10-60 wt. %, photo-initiator 1-10 wt. %, and accessory materials 0-10 wt. %. The adhesive has such advantages as high adhesiveness to metals and glass, good solvent resistance, good water-boiling resistance, high curing rate, low energy consumption and high productivity.
Description
Technical field
Patent of the present invention relates to a kind of ultraviolet solidified adhesive, and particularly a kind of ultraviolet solidified adhesive that is used for sticking metal pin in liquid crystal display is LCD pin glue or LCD folder PIN glue again.
Background technology
At present, domestic liquid crystal display device is the general ultraviolet solidified adhesive that adopts import when the bonded metal pin, and the ultraviolet solidified adhesive of domestic production seldom.The essentially consist of ultraviolet solidified adhesive is: (1) prepolymer; (2) reactive monomer; (3) light trigger; (4) auxiliary agent.The ultimate principle of ultraviolet solidified adhesive is: after tens of seconds, light trigger decomposes the generation radical makes its polymerizing curable to main gel, and makes it change reticulated structure into by linear structure in UV-irradiation.The ultraviolet solidified adhesive that is used for sticking metal pin in liquid crystal display, need stand following endurance test:
(1) boiling test: can not come off with manual glue after 100 ℃ * 8 hours;
(2) hot and humid endurance test: 80 ℃ * 90%RH * 400 hours;
(3) organic solvent-resistant test: in acetone, soaked 4 minutes respectively and alcohol in soak after 30 minutes not dry linting foam of glue;
But existing homemade ultraviolet solidified adhesive can't satisfy above-mentioned every requirement simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of novel ultraviolet solidified adhesive that is used for sticking metal pin in liquid crystal display, it can remedy the above-mentioned deficiency of existing homemade ultraviolet solidified adhesive.
Ultraviolet solidified adhesive of the present invention comprises: (1) prepolymer; (2) reactive monomer; (3) light trigger; (4) auxiliary agent, its each component concentration is (weight percent): prepolymer 30-80%; Reactive monomer 10-60%; Light trigger 1-10% auxiliary agent 0-10%.
Prepolymer described in the ultraviolet solidified adhesive of the present invention is aliphatic urethane acrylate and modified epoxy acrylic ester, as the M1800 of CN981, CN1963, CN966J75 and CN104, CN151 and the Taiwan Shi Mei company of SARTOMER company and M6200 etc.
Reactive monomer described in the ultraviolet solidified adhesive of the present invention is the simple function group acrylate, as isobornyl methacrylate, Rocryl 410 and hydroxyethyl methylacrylate etc.
Light trigger described in the ultraviolet solidified adhesive of the present invention is D-1173, I-184 and the TPO of vapour Bagong department.
Auxiliary agent described in the ultraviolet solidified adhesive of the present invention is a silane coupling agent, as domestic trade mark KH550, KH560 and KH570 etc.
The preparation method of ultraviolet solidified adhesive of the present invention is: the light trigger of 1-10% is dissolved in the acrylate monomer of 10-60%, be heated to 30-60 ℃, after treating that solid all dissolves, the prepolymer that adds 30-80%, continuation stirs under 30-60 ℃ of temperature, and the silane coupled agent aid that adds 0-10% at last mixes.
