Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a frame sealing adhesive 10, as shown in fig. 2, including a filler 20 and a spacer 30 doped in the filler 20; the spacer 30 is strip-shaped and can transmit light; as shown in fig. 3(a), the strip-shaped spacer 30 is composed of a first sub spacer 301 and a second sub spacer 302 along the length direction thereof; wherein, at least the end of the first sub-spacer 301 far away from the second sub-spacer 302 has polarity.
First, the material of the filler 20 is not limited, but the filler 20 preferably has excellent adhesive strength to a metal or nonmetal material after curing, and has advantages of small shrinkage, high hardness, and the like. The material of the filler 20 may be, for example, a polymer material such as a polymer system mainly including an epoxy resin or an acrylate.
Secondly, the function of the frame sealing adhesive 10 is mainly to bond the two substrates together and keep a certain distance between the two substrates, because the hardness of the filler 20 is small, the spacer 30 needs to be doped in the filler 20, the spacer 30 is used for supporting, and the proportion of the spacer 30 in the frame sealing adhesive 10 is not limited, so that the frame sealing adhesive 10 has good viscosity and certain hardness. The implementation of the invention is preferable, and the mass fraction of the spacer 30 in the frame sealing glue 10 is 1% -2%. For example, the frame sealing adhesive 10 has a mass of 100, the spacer 30 has a mass of 1, and the filler 20 has a mass of 99.
Thirdly, the material of the spacer 30 is not limited to allow light to pass through, and all the material of the spacer 30 may be transparent; the material of the portion of the spacer 30 that transmits light may be transparent.
Fourthly, the length of the first sub-spacer 301 and the length of the second sub-spacer 302 in the spacer 30 are not limited, and the length of the first sub-spacer 301 may be greater than the length of the second sub-spacer 302; the length of the second sub-spacer 302 may be longer than that of the first sub-spacer 301; it is of course also possible that the length of the first sub-spacer 301 and the length of the second sub-spacer 302 are equal.
Fifth, at least the end of the first subpad 301 away from the second subpad 302 has a polarity, where the polarity may be positive, i.e. with a positive charge; or may have a negative polarity, i.e. a negative charge.
In the embodiment of the present invention, since the end of the first sub-spacer 301 away from the second sub-spacer 302 has polarity, the spacers 30 are arranged in a certain orientation, i.e., parallel or approximately parallel to the direction of the electric field, under the action of the electric field. As shown in fig. 3(b), taking the positive polarity at the end of the first sub-spacer 301 away from the second sub-spacer 302 as an example, the electric field is applied to the frame sealing adhesive 10, the end of the first sub-spacer 301 with positive polarity approaches to the side with low voltage in the electric field, and the second sub-spacer 302 approaches to the side with high voltage, so that the spacers 30 in the frame sealing adhesive 10 can be arranged in a certain orientation, that is, the length direction of the spacers 30 is parallel or approximately parallel to the direction of the electric field.
On this basis, it may be that the end of the first sub-spacer 301 that is far from the second sub-spacer 302 has polarity; it is also possible that the first subpad 301 has a polarity everywhere. When the end of the first sub-spacer 301 away from the second sub-spacer 302 has polarity, there is no limitation on the ratio of the length of the portion having polarity in the first sub-spacer 301 to the length of the first sub-spacer 301, so that the spacer 30 can rotate under the action of the electric field after the electric field is applied. The longer the length of the portion having polarity in the first sub-spacer 301, the easier the spacer 30 rotates after the electric field is applied.
The embodiment of the invention provides a frame sealing adhesive 10, wherein a spacer 30 in the frame sealing adhesive 10 is composed of a first sub-spacer 301 and a second sub-spacer 302, and at least the end part of the first sub-spacer 301 far away from the second sub-spacer 302 has polarity, so that if an electric field is applied in the process of coating the frame sealing adhesive 10, the spacers 30 in the frame sealing adhesive 10 are arranged according to a certain orientation, and thus when the frame sealing adhesive 10 is subjected to photocuring (for example, UV light), because the spacers 30 in the frame sealing adhesive 10 are arranged according to a certain orientation, the blocking of light can be reduced, and compared with the prior art that the spacers 30 are distributed in a disordered manner, the spreading distance of the light is increased due to the arrangement of the spacers 30 according to a certain orientation, the curing depth of the frame sealing adhesive 10 is increased, and further the curing rate of the frame sealing adhesive 10 is improved.
Generally, the curing rate of the frame sealing adhesive 10 according to the embodiment of the present invention can reach about 80%.
Preferably, as shown in fig. 4, at least the end of the second sub-spacer 302 away from the first sub-spacer 301 has a polarity, and the polarity of the first sub-spacer 301 is opposite to the polarity of the second sub-spacer 302.
Wherein, it may be that the end of the second sub-spacer 302 away from the first sub-spacer 301 has a positive polarity, i.e. carries a positive charge, and the first sub-spacer 301 away from the second sub-spacer 302 has a negative polarity, i.e. carries a negative charge; it is also possible that the first sub-spacer 301 has a positive polarity, i.e. carries a positive charge, away from the second sub-spacer 302, and the end of the second sub-spacer 302 remote from the first sub-spacer 301 has a negative polarity, i.e. carries a negative charge.
Here, it may be that the end of the second sub-spacer 302 away from the first sub-spacer 301 has polarity; it is also possible that the second subpad 302 has polarity everywhere. When the end of the second sub-spacer 302 away from the first sub-spacer 301 has polarity, there is no limitation on the ratio of the length of the portion having polarity in the second sub-spacer 302 to the length of the second sub-spacer 302. On this basis, it may be that the end of the second sub-spacer 302 away from the first sub-spacer 301 has polarity, and the first sub-spacer 301 has polarity everywhere; it is also possible that the end of the first sub-spacer 301 remote from the second sub-spacer 302 has a polarity and the second sub-spacer 302 has a polarity everywhere.
In the embodiment of the present invention, at least the end of the second sub-spacer 302 away from the first sub-spacer 301 has a polarity, and the polarity of the first sub-spacer 301 is opposite to the polarity of the second sub-spacer 302, so that if an electric field is applied during the coating process of the frame sealing adhesive 10, the spacers 30 can be rapidly arranged in a certain orientation (parallel or approximately parallel electric field direction), and the arrangement of the spacers 30 can be more orderly, thereby further reducing the blocking of light and facilitating the transmission of light.
Alternatively, as shown in fig. 5, the spacer 30 includes a transparent core 303 including two bottom surfaces and a side surface connected to the two bottom surfaces; the spacer 30 further includes a wrapping layer 304 wrapping the sides of the core 303; wrapping layer 304 has a polarity.
It should be noted that, the spacer 30 is a strip, so the core 303 is also a strip, if the core 303 is a cylinder, two bottom surfaces of the core 303 refer to an upper bottom surface and a lower bottom surface, and a side surface refers to a side surface of the cylinder; if the core 303 is a rectangular parallelepiped, two bottom surfaces of the core 303 mean two opposing surfaces having the smallest area, and the other surfaces of the rectangular parallelepiped mean side surfaces.
Here, since the core 303 of the spacer 30 is transparent and the wrapping layer 304 covers only the side of the core 303, light can be transmitted through the core 303. In this regard, encapsulation 304 may or may not be transparent.
The material of the core 303 is not limited to be capable of transmitting light, and for example, the material of the core 303 may be glass fiber.
The material of wrapping layer 304 is not limited as long as wrapping layer 304 has polarity. The wrapping layer 304 has polarity, and may be, as shown in fig. 6(a) and 6(b), the wrapping layer 304 of the first subpad 301 has polarity; alternatively, as shown in fig. 6(c) and 6(d), the wrapping layer 304 of the second subpad 302 may have a polarity; it is of course also possible that as shown in fig. 7(a) and 7(b), the wrapping layer 304 of the first sub-spacer 301 and the wrapping layer 304 of the second sub-spacer 302 have both polarities, and the wrapping layer 304 of the first sub-spacer 301 has a polarity opposite to the polarity of the wrapping layer 304 of the second sub-spacer 302 (fig. 7(a) and 7(b) are illustrated by way of example in which the wrapping layer 304 of the first sub-spacer 301 has a positive polarity and the wrapping layer 304 of the second sub-spacer 302 has a negative polarity).
On this basis, the wrapping layer 304 of the first sub-spacer 301 has polarity, which may be that the wrapping layer 304 of the first sub-spacer 301 has polarity everywhere as shown in fig. 6(b), or that the portion of the wrapping layer 304 of the first sub-spacer 301 away from the second sub-spacer 302 has polarity as shown in fig. 6(a), that is, the end portion of the first sub-spacer 301 away from the second sub-spacer 302 has polarity; similarly, the wrapping layer 304 of the second sub-spacer 302 has a polarity, which may be the polarity at the wrapping layer 304 of the second sub-spacer 302 as shown in fig. 6(d), or the polarity at the portion of the wrapping layer 304 of the second sub-spacer 302 away from the first sub-spacer 301 as shown in fig. 6(c), that is, the polarity at the end of the second sub-spacer 302 away from the first sub-spacer 301.
In the embodiment of the invention, the spacer 30 comprises the core 303 and the wrapping layer 304, and the core 303 is made of transparent material, so that light can penetrate through the core 303; because the wrapping layer 304 has polarity, if an electric field is applied in the process of coating the frame sealing adhesive 10, the length direction of the spacers 30 is arranged in the direction parallel or approximately parallel to the electric field under the action of the electric field, so that the blocking of light can be reduced, the propagation distance of the light in the frame sealing adhesive 10 can be increased, and the curing rate of the frame sealing adhesive 10 can be improved.
It is further preferred that the material of core 303 is an Optical Fiber (Optical Fiber).
Among them, an optical fiber, also called an optical fiber, is a fiber made of glass or plastic, and can be used as a light transmission means.
In the embodiment of the present invention, when the material of the core 303 is an optical fiber, as shown in fig. 8(a) and 8(b) (an example of a spacer 30 is shown in fig. 8 (b)), the optical fiber not only can transmit light, but also can transmit light, so that the propagation distance of light is increased, and compared with a common transparent material, because the optical fiber can transmit light, the propagation distance of light in the sealant 10 is further, therefore, the material of the core 303 is preferably the optical fiber in the embodiment of the present invention, so that the spacer 30 formed in this way not only can play a supporting role, but also can play a role in transmitting light, and the curing rate of the sealant 10 is improved.
Preferably, the material of wrapping layer 304 is a resin.
In the embodiment of the invention, when the material of the wrapping layer 304 is resin, the resin is transparent, so that light can pass through the resin, and the curing rate of the frame sealing adhesive 10 can be improved. In addition, the filler 20 of the frame sealing adhesive 10 is generally epoxy resin, and when the wrapping layer 304 is made of resin, the filler 20 and the spacer 30 have good physical compatibility according to the principle of similarity and compatibility, so as to provide the bonding strength of the frame sealing adhesive 10.
Preferably, as shown in fig. 6(b), 6(d) and 7(b), the wrapping layer 304 of the first sub-spacer 301 has polarity everywhere; and/or the wrapping 304 of the second subpad 302 may have a polarity everywhere.
Here, it may be that the wrapping 304 of the first sub-spacer 301 has polarity everywhere, the wrapping 304 of the second sub-spacer 302 has no polarity, or the portion of the wrapping 304 of the second sub-spacer 302 has polarity; it is also possible that the wrapping 304 of the second subpad 302 has a polarity everywhere, the wrapping 304 of the first subpad 301 has no polarity, or the portion of the wrapping 304 of the first subpad 301 has a polarity; it is of course also possible that the wrapping 304 of the first sub-spacer 301 has a polarity everywhere, the wrapping 304 of the second sub-spacer 302 has a polarity everywhere, and the polarity of the wrapping 304 of the first sub-spacer 301 is opposite to the polarity of the wrapping 304 of the second sub-spacer 302.
In the embodiment of the invention, the wrapping layer 304 of the first sub-spacer 301 has polarity, and the wrapping layer 304 of the first sub-spacer 301 has polarity everywhere, so that the wrapping layer 304 of the first sub-spacer 301 has higher polarity, and the spacer 30 is easier to rotate quickly under the action of an electric field; similarly, the wrapping 304 of the second subpad 302 may have a polarity everywhere relative to the wrapping 304 of the second subpad 302, which may make the wrapping 304 of the second subpad 302 more polar, and thus the spacer 30 may be more easily rotated at a high speed by the electric field.
It is further preferred that the length of the first sub-spacer 301 is the same as the length of the second sub-spacer 302, with the wrapping 304 of the first sub-spacer 301 having polarity and the wrapping 304 of the second sub-spacer 302 having polarity as shown in fig. 7 (b).
Here, the polarity of the wrapping layer 304 of the first sub-spacer 301 is opposite to that of the wrapping layer 304 of the second sub-spacer 302.
In the embodiment of the present invention, when the length of the first sub-spacer 301 is the same as that of the second sub-spacer 302, the length of the wrapping layer 304 of the first sub-spacer 301 is the same as that of the wrapping layer 304 of the second sub-spacer 302, and the wrapping layer 304 of the first sub-spacer 301 has a polarity at its place, and the wrapping layer 304 of the second sub-spacer 302 has a polarity at its place, so that the magnitude of the polarity of the first sub-spacer 301 is the same as that of the polarity of the second sub-spacer 302, and thus if an electric field is applied in the process of coating the sealant 10, the magnitude of the electric field force applied to the first sub-spacer 301 is the same as that applied to the second sub-spacer 302, so that the spacers 30 can be uniformly distributed in the filler 20, and the length direction of the spacers 30 is parallel to the direction of the electric field.
Optionally, the spacer 30 is made of a transparent material.
When the material of the spacer 30 is a transparent material, the specific material of the spacer 30 is not limited, and may be, for example, glass fibers, and if at least an end of the first sub-spacer 301 away from the second sub-spacer 302 has a polarity, the glass fibers of the portion having the polarity have the polarity.
In the embodiment of the present invention, when the material of the spacer 30 is a transparent material, light can continue to propagate through the transparent material.
