Description
Technical Field
The invention relates to a photo-curing adhesive composition for screen edge sealing and application thereof.
Background
With the market change, the frames of the LCD and OLED display screens are becoming narrower and narrower to improve the screen ratio and better visual effect. For narrow frames, the traditional adhesive tape attaching process is high in operation difficulty and low in yield, so that more and more manufacturers use an adhesive attaching and edge sealing mode instead.
Polyurethane (PU) adhesives are a class of high polymers that are polymerized from isocyanates and oligomeric polyols. The main chain of the polyurethane material contains a large amount of carbamate groups, so that the polyurethane material has the advantages of high strength, high wear resistance, high elasticity, excellent low temperature resistance and the like, and the hardness of the polyurethane material can be adjusted in a large range, so that the polyurethane material is widely applied to the fields of adhesives, coatings, composite materials and the like.
For another example, chinese patent document CN105733492A discloses a light-cured adhesive composition capable of adsorbing fine dust, which comprises the following components in parts by mass: 30-70% of polyurethane acrylate oligomer, 20-60% of acrylate monomer, 1-6% of photoinitiator and 0.1-5% of carbon black, wherein the surface tension of the polyurethane acrylate oligomer is more than 48dyne/cm, and the viscosity at 25 ℃ is 8000mPa.s-10000 mPa.s. The adhesive composition has good aging resistance, is cured by UV light, is not influenced by the environmental temperature, avoids the problem of accessory damage caused by heating for shortening the curing time, is pollution-free and high in safety, but cannot meet the requirements of high ultraviolet curing speed and high OD value. These two requirements are contradictory in the sense that a glue with a high OD value absorbs uv light, which results in a poor curing of the glue and a failure to meet the bonding strength requirements.
Disclosure of Invention
One of the technical problems to be solved by the invention is that the effects of fast ultraviolet curing and high OD value cannot be simultaneously obtained and the bonding strength is low in the prior art, and a novel light-curing adhesive composition for screen edge sealing is provided. The second technical problem to be solved by the invention is to provide the application of the novel photo-curing adhesive composition for screen edge sealing.
One of the technical solutions adopted by the present invention to solve the above technical problems is as follows: the light-curing adhesive composition for the screen edge sealing comprises the following components in percentage by mass: 50-60% of polyurethane acrylate oligomer, 30-40% of acrylate monomer, 3-5% of photoinitiator, 1-3% of visible light absorber and 0.2-4% of carbon black, wherein the visible light absorber can effectively absorb visible light with the wavelength of 400-800 nm.
In the above technical solution, preferably, the visible light absorber may be selected from at least one of zirconium carbide powder, BL 1226 or IRAOYP 01.
Preferably, the acrylate monomer is selected from at least one of 2- (ethoxy) ethoxyethacrylic acid, hydroxyethyl acrylate, hydroxypropyl acrylate, tetraethylene glycol diacrylate or ethoxylated trimethylolpropane triacrylate.
More preferably, the acrylate monomer is selected from at least one of 2- (ethoxy) ethoxyethacrylic acid or hydroxyethyl acrylate.
More preferably, the acrylate monomer is selected from the group consisting of a mixture of 2- (ethoxy) ethoxyethacrylic acid and hydroxyethyl acrylate; the mass ratio of the 2- (ethoxy) ethoxy ethyl acrylic acid to the hydroxyethyl acrylate is 5: 2.
preferably, the photoinitiator is selected from the group consisting of 2-hydroxy-methylphenylpropane-1-one, 1-hydroxycyclohexylphenylketone, 2-methyl-1- (4-methylthiophenyl) -2-morpholinyl-1-propanone, benzoin bis methyl ether BDK, 2,4, 6-trimethylbenzoyl-diphenylphosphine oxide, isopropylthioxanthone (2, 4 isomeric mixture), ethyl 4- (N, N-dimethylamino) benzoate, at least one of benzophenone, 4-chlorobenzophenone, methyl o-benzoylbenzoate, diphenyliodonium salt hexafluorophosphate, p-isooctyl N, N-dimethylaminobenzoate, 4-methylbenzophenone, methyl o-benzoylbenzoate or 4-phenylbenzophenone.
More preferably, the photoinitiator is selected from the group consisting of a mixture of 1-hydroxycyclohexyl phenyl ketone and 2,4, 6-trimethylbenzoyl-diphenylphosphine oxide; the mass ratio of the 1-hydroxycyclohexyl phenyl ketone to the 2,4, 6-trimethylbenzoyl-diphenyl phosphine oxide is 3: 1.
Preferably, the urethane acrylate is an aliphatic urethane acrylate.
The second technical solution adopted by the present invention to solve the above technical problems is as follows: the application of the light-cured adhesive composition for the screen edge sealing in the edge sealing of LCD and OLED screens.
The invention adopts polyurethane as base glue, adds photoinitiator into the polyurethane, and generates active free radicals after absorbing high-intensity ultraviolet light in Ultraviolet (UV) light curing equipment, thereby initiating polymerization, crosslinking and grafting reaction, leading the resin to be converted from liquid state to solid state within seconds, and meeting the requirement of rapid curing.
The invention is favorable for solving the problems of surface curing and deep curing of the glue by adopting the photoinitiator, and particularly, the invention better solves the problems of surface curing and deep curing of the glue by adopting the matching of 1-hydroxycyclohexyl phenyl ketone with short wave absorption and 2,4, 6-trimethylbenzoyl-diphenyl phosphine oxide with long wave absorption in the mass ratio of 3: 1. Mainly because 1-hydroxycyclohexyl phenyl ketone absorbs short UVB wave and is beneficial to surface layer drying, and 2,4, 6-trimethylbenzoyl-diphenyl phosphine oxide absorbs long UVA wave and is beneficial to deep curing.
The OD value can reach more than 0.5 (the lowest OD value requirement of screen light leakage prevention) by adding carbon black (capable of absorbing visible light) and a visible light absorbent in the formula.
The invention adopts the technical scheme that the mass ratio of the propyl 2- (ethoxy) ethoxy ethyl acrylic acid to the hydroxyethyl acrylate is 5: 2, the two acrylates are used in a matching way, so that the adhesive strength is ensured, and meanwhile, the elasticity of the adhesive composition is increased, and the adsorption capacity of the surface of the curing adhesive is further enhanced.
When the light-cured adhesive composition is used for screen edge sealing by adopting the technical scheme of the invention, the inventor surprisingly finds that the bonding strength is further enhanced while the effects of fast ultraviolet curing and high OD value are kept. The ultraviolet curing time can be 5s as fast as possible, the ultraviolet curing time is shortened by 75% compared with 20s in the prior art, the OD value is 0.87 as high as 74% compared with 0.5 in the prior art, the bonding strength can be 26N as high as possible, the 12N in the prior art is increased by 117%, and a good technical effect is achieved.
The invention is further illustrated by the following examples.
