Thus, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.
The embodiment of the invention provides frame sealing glue and a liquid crystal display panel. The details will be described below.
Examples
In the liquid crystal display panel, the frame sealing glue mainly plays a role in connecting and sealing a first substrate and a second substrate which are oppositely arranged, and forms a liquid crystal box together with the first substrate and the second substrate so as to prevent water vapor from entering; meanwhile, the frame sealing glue is also used for supporting the first substrate and the second substrate, so that a gap is formed between the first substrate and the second substrate, and a stable and reliable box interior environment is maintained, so that the strength and the flexibility of the frame sealing glue are key factors influencing the display performance of the liquid crystal display panel.
An embodiment of the present invention provides a frame sealing adhesive, as shown in fig. 1, a frame sealing adhesive 10 includes: the sealant 10 further includes an aramid nanofiber 13, and the sealant includes a resin 11, an epoxy oligomer (not shown), a curing agent (not shown), and a filler 12.
According to the embodiment of the invention, the aramid fiber nanofiber 13 is added into the frame sealing glue 10, and the aramid fiber nanofiber 13 and the resin 11 form a three-dimensional net structure, so that the frame sealing glue 10 has high strength and high flexibility; meanwhile, after the aramid nanofibers 13 are added into the frame sealing glue 10, the structure of the frame sealing glue 10 is more compact, moisture permeation can be prevented, and the low-humidity permeability of the frame sealing glue 10 is improved.
The Aramid Nanofibers (ANFs) are heat-resistant and firm synthetic fibers, chain molecules of the aramid nanofibers are highly oriented along the axial direction of the fibers and have excellent heat resistance, and researches show that compared with other fiber composite materials, the aramid nanofibers have more excellent strength and flexibility, particularly, the aramid nanofibers have a special rich branch structure and a large specific surface area, and are easy to form stronger intermolecular force with the contacted resin 11, so that the aramid nanofibers are compounded to form a three-dimensional network structure, and the three-dimensional network structure has better capability of dispersing local stress and bearing external pressure, so that the aramid nanofibers are added into the frame sealing adhesive 10, and the strength and flexibility of the frame sealing adhesive 10 can be obviously improved.
Further, in some embodiments of the present invention, the aramid nanofibers 13 are branched flexible aramid nanofibers. The aramid nano-fiber 13 is branched, so that two branches of the aramid nano-fiber 13 can be increased, the specific surface area of the aramid nano-fiber 13 is further increased, the branch structure of the aramid nano-fiber 13 is richer, and the strength, flexibility and low-moisture-permeability of the frame sealing glue 10 are further improved; meanwhile, the flexibility of the frame sealing glue 10 can be further improved by the aramid nano-fiber 13 being flexible.
It should be understood that: the adding proportion of the aramid nano-fiber 13 can be adjusted according to actual conditions, so that the frame sealing glue 10 has both strength and flexibility.
It should be noted that: the preparation process of the aramid nanofiber 13 is as follows: the aramid nanofiber 13 is prepared by taking aromatic polyimide fiber (Kevlar) large-size fiber (KMF) as a raw material, adding the KMF into dimethyl sulfoxide (DMSO), adding saturated potassium hydroxide (KOH), and carrying out deprotonation reaction on the KMF and the saturated KOH to carry out chemical splitting on the KMF.
Further, as shown in fig. 1, in some embodiments of the present invention, the aramid nanofibers 13 are uniformly dispersed in the resin 11, and the aramid nanofibers 13 form a three-dimensional network structure with the resin 11. The aramid nanofibers 13 are uniformly distributed in the resin 11, so that the homogenization of a three-dimensional network structure can be realized, and the uniformity of the overall performance of the frame sealing glue 10 can be improved. Meanwhile, when the frame sealing adhesive 10 has a three-dimensional network structure, the material of the frame sealing adhesive 10 can be optimally designed in structure, and the material performance of the frame sealing adhesive 10 can be better adjusted and controlled.
Further, in some embodiments of the present invention, the diameter of the aramid nanofibers 13 is 4.5 nanometers and the length of the aramid nanofibers 13 is 1 micrometer to 2 micrometers. In particular, as can be seen in fig. 1: the aramid nano-fiber 13 is composed of a plurality of branched aramid nano-fibers, the diameters of the branched aramid nano-fibers are the same and are 4.5 nanometers, and the total length of the branched aramid nano-fibers is 1 micrometer-2 micrometers.
Further, in some embodiments of the present invention, the resin 11 includes an acryl resin and an epoxy resin. Preferably, the resin 11 is a mixture of an acryl resin and an epoxy resin, and particularly, the resin 11 is a mixture of polymethyl methacrylate and bisphenol a epoxy resin.
It should be noted that: the proportion of the acrylic resin and the epoxy resin in the resin 11 should be adjusted according to actual conditions, specifically: if the content of the acrylic resin is too high and the content of the epoxy resin is too low, the hardness and the adhesive force of the frame sealing glue 10 formed after curing are small; if the content of the acrylic resin is too low and the content of the epoxy resin is too high, the cured frame sealing adhesive 10 has high hardness and brittleness and is easily damaged.
It should be understood that: the aramid nanofibers 13 are uniformly dispersed in the acrylic resin and the epoxy resin.
Further, in some embodiments of the present invention, the curing agent comprises a thermal curing agent. The curing mechanism of the thermal curing agent is that when the temperature reaches a certain condition, the epoxy oligomer in the frame sealing adhesive 10 and the thermal curing agent undergo a polymerization reaction to form the solid frame sealing adhesive 10.
Further, in order to improve the curing capability of the frame sealing adhesive 10, in some embodiments of the present invention, the curing agent further includes at least one of a light curing agent and a moisture curing agent.
It should be noted that: correspondingly, the frame sealing adhesive 10 further includes a polyacrylate oligomer, and the polyacrylate oligomer and the light curing agent undergo a polymerization reaction under the irradiation of ultraviolet light (UV) to form the solid frame sealing adhesive 10. The curing agent mechanism of the moisture curing agent is that the epoxy oligomer and the moisture curing agent are subjected to polymerization reaction when moisture reaches a certain condition, so as to form the solid frame sealing adhesive 10.
This is due to: the epoxy oligomer needs to be cured at a high temperature for a long time, a small part of the epoxy oligomer is not completely reacted in the thermosetting process, and after the thermosetting process, the moisture curing initiator starts to act along with the accumulation of water vapor on the interface of the frame sealing glue 10, so that the epoxy oligomer which is not completely reacted in the frame sealing glue 10 continues to react, and the adhesion of the frame sealing glue 10 is increased. The influence of water on the mechanical strength of the frame sealing glue 10 is solved, and the reliability of the frame sealing glue 10 is improved.
Furthermore, the moisture curing process needs to be performed under the conditions of low temperature and a small amount of water, the UV curing process absorbs energy, and the thermal curing process needs to be performed under high temperature conditions, so that the moisture curing agent does not react during the UV curing and the thermal curing process or when excessive water exists in the environment, and the moisture curing process must occur after the UV curing and the thermal curing, such as during the use of the display device, so that the moisture entering during the use can be consumed, the influence of the moisture on the service life can be reduced, and the adhesion performance and the mechanical strength of the frame sealing adhesive 10 can be further improved. Since the moisture curing only improves the adhesion performance and the mechanical strength of the frame sealing adhesive 10, if the moisture curing reaction degree is low or no reaction occurs, the normal use of the frame sealing adhesive 10 itself will not be affected.
The frame sealing glue 10 has the functions of photocuring, thermocuring and moisture curing, and the reliability and the safety of the frame sealing glue 10 can be improved.
It should be understood that: the adding proportion of the light curing agent, the moisture curing agent and the heat curing agent can be adjusted according to actual conditions.
Specifically, the light curing agent comprises one or more of benzophenone, acetophenone, alpha-hydroxy ketone and alpha-amino ketone.
Specifically, the heat-curing agent comprises one or more of ethylenediamine, diethylenetriamine, triethylene tetramine, m-phenylenediamine and aromatic polyamine.
Specifically, the moisture curing agent is a lewis acid initiator, and the lewis acid initiator comprises one or more of TiCl4, TiBr2, AlCl3, AlBr3, SnCl4, ZnCl2 and other lewis acids.
Further, in some embodiments of the present invention, the filler 12 is any one of silica, zinc oxide, alumina, titanium oxide, calcium carbonate, and zinc tungstate. The filler 12 is used to maintain the shape of the frame sealing adhesive 10 after curing, and fill the gap between the first substrate and the second substrate with liquid crystal.
Further, in some embodiments of the present invention, the filler 12 is silica.
Further, in some embodiments of the present invention, as shown in fig. 1, the silica is spherical in shape and has a diameter of 1.2 microns to 6 microns.
It should be understood that the frame sealing adhesive 10 in the embodiment of the present invention may further include other additives to improve other properties of the frame sealing adhesive 10. For example, the frame sealing adhesive 10 further includes a stabilizer for improving the stability of the frame sealing adhesive 10, and the stabilizer is usually selected from stabilizers of epoxy resin systems, such as N-phenyl- β -naphthylamine, 2, 6-di-tert-butyl-p-cresol, and the like; the frame sealing glue 10 may further include one or more of a plasticizer, a silane coupling agent and a polymerization inhibitor; the plasticizer comprises one or more of phthalate, phosphate, oxalate and sebacic acid ester; the polymerization inhibitor comprises one or more of hydroquinone, anthraquinone and p-methoxyphenol.
When the frame sealing glue 10 is manufactured, the resin 11, the epoxy oligomer, the aramid nanofiber 13 and the like are sequentially mixed and defoamed, then the curing agent is added, the mixture is mixed and defoamed again to obtain a frame sealing glue theme, and before the frame sealing glue is cured and used, the filler 12 is added into the frame sealing glue main body, and the mixture is defoamed to obtain the frame sealing glue 10.
As shown in fig. 2, an embodiment of the present invention further provides a liquid crystal display panel, where the liquid crystal display panel 100 includes a first substrate 20, a second substrate 30 and a sealant 10 connecting the first substrate 20 and the second substrate 30, where the sealant 10 is the sealant 10 in any of the above embodiments. In general, the first substrate 20 is an array substrate and includes a first substrate, a driving circuit layer, and a pixel electrode, which are stacked, and the second substrate 30 is a color film substrate and includes a second substrate, a black matrix, a color resist layer, and a common electrode, which are stacked.
