Detailed Description
The technical solutions of the present disclosure will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only some embodiments of the present disclosure, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present disclosure without making any creative effort belong to the protection scope of the present disclosure. In addition, technical features involved in different embodiments of the present disclosure described below may be combined with each other as long as they do not conflict with each other.
With the overall development of mobile terminals, the requirements of consumers on the appearance and texture of electronic devices are increasing, and taking a smart phone as an example, fig. 1 shows an appearance structure of the smart phone, which is described below with reference to fig. 1. It will be understood by those skilled in the art that the electronic device is not limited to a smart phone, but may be any other device type suitable for implementation, such as a tablet computer, a wearable device, an e-book reader, a multimedia player, etc., and the disclosure is not limited thereto.
As shown in fig. 1, the electronic device 10 includes a housing 100 and a display 200, and the display 200 is connected to the housing 100. In some embodiments, the housing may include a middle frame 110 and a back plate 120, the back plate 120 and the display screen 200 are respectively connected to two sides of the middle frame 110 and form a receiving space, and electrical components such as a main board, a sensor, and an antenna of the electronic device 10 are disposed in the receiving space. In some embodiments, the middle frame 110 and the back plate 120 may also be an integrally formed structure, which is not limited by the present disclosure.
In the related art, the back plate 120 of the electronic device 10 is generally made of glass, composite board, ceramic, and other materials, and is limited by materials and processes, and the back plate 120 of the related art has the disadvantages of brittle quality, low strength, and high density, thereby resulting in low back plate yield, high overall quality, and high maintenance cost.
The glass fiber is artificial fiber, has the advantages of high tensile strength, high strength, good temperature resistance and the like, and the glass fiber board prepared by the glass fiber has the characteristics of high strength and low density, and can further improve the strength of the backboard and reduce the weight when being used for the backboard of the electronic equipment. However, the surface of the glass fiber board is low and is white or semitransparent, so that the glass fiber board used for the electronic equipment backboard is difficult to manufacture rich appearance effects, and the development and popularization of the glass fiber in the field of electronic equipment are limited.
Based on the defects of the related technologies, the embodiment of the disclosure provides a glass fiber board, a preparation method thereof and a related product with the glass fiber board, and aims to enrich the appearance effect of the glass fiber board and facilitate the popularization and application of the glass fiber board in the field of electronic devices.
The embodiment of the disclosure provides a glass fiber board, and the glass fiber board comprises at least two layers of glass fiber substrates and at least one layer of decorative layer which are arranged in a stacked mode. The glass fiber substrate comprises at least one prepreg layer, and the prepreg layer comprises glass fiber cloth woven by glass fiber yarns and a binder at least filled in gaps of the glass fiber cloth. The decorative layer is arranged in the middle layer of the at least two layers of glass fiber substrates.
In the embodiment of the disclosure, for the prepreg layer forming the glass fiber substrate, the difference value between the first refractive index of the binder and the second refractive index of the glass fiber cloth is within a preset range.
It should be noted that, as described above, in the related art, the glass fiber sheet itself appears white or translucent, and thus the appearance effect is limited. It was found through research that this is because the difference in refractive index between the glass fiber step and the binder in the glass fiber sheet is large, resulting in poor transparency of the glass fiber sheet.
In the embodiment of the present disclosure, a difference between the first refractive index of the glass cloth and the second refractive index of the adhesive is within a predetermined range. That is, the refractive index of the glass fiber cloth is as close as possible to that of the binder, so that the obtained prepreg has good transparency, and the appearance effect of the glass fiber board can be realized subsequently.
The process of preparing the prepreg layer is specifically described in the following of the present disclosure, and will not be described in detail herein.
Therefore, in the embodiment of the disclosure, the appearance effect of the glass fiber board is enriched, and the popularization and application of the glass fiber board in the field of electronic equipment are facilitated.
Embodiments of the present disclosure provide a method of manufacturing a glass fiber sheet, which may be used to manufacture a glass fiber sheet having a decorative appearance effect.
As shown in fig. 2, in some embodiments, a method of making a glass fiber sheet, exemplary of the present disclosure, includes:
and S210, obtaining the glass fiber cloth woven by the glass fiber yarns.
The glass fiber yarns are single glass fiber yarns, and a plurality of glass fiber yarns are sequentially woven in an inserting manner to obtain the woven glass fiber cloth.
In some embodiments, the woven structure of the glass fiber cloth can be as shown in fig. 3, a plurality of first glass fiber threads 1 are arranged at intervals along a first direction, and then a plurality of second glass fiber threads 2 are sequentially inserted into the gaps of the first glass fiber threads 1, so as to obtain the woven glass fiber cloth. It can be understood by those skilled in the art that, in the embodiments of the present disclosure, the weaving manner of the glass fiber cloth is not limited, and may be any weaving structure suitable for implementation, which is not described in detail herein.
And S220, impregnating the glass fiber cloth with the binder so that the binder fills gaps of the glass fiber cloth, thereby obtaining the prepreg.
It can be understood that the glass fiber cloth woven by the glass fiber yarns is a single-layer cloth which is flexible and ductile, and the glass fiber cloth needs to be impregnated with a binder in order to improve the structural strength of the glass fiber plate.
In some embodiments, the binder may include a resin that is liquid or semi-liquid at a particular temperature. By impregnating the fiberglass cloth with resin, a liquid or semi-liquid resin adhesive can be filled in the gaps of the fiberglass cloth as shown in fig. 3, and after the resin is cured, the composite prepreg of the resin and the fiberglass cloth with certain structural strength can be obtained.
It should be noted that, as described above, in the related art, the glass fiber sheet itself appears white or translucent, and thus the appearance effect is limited. It is found through research that this is because the difference between the refractive index of the glass fiber step and that of the binder in the glass fiber board is large, which results in poor transparency of the glass fiber board.
In the embodiment of the present disclosure, a difference between the first refractive index of the glass fiber cloth and the second refractive index of the adhesive is within a predetermined range. That is, the refractive index of the glass fiber cloth is as close as possible to that of the binder, so that the obtained prepreg has good transparency, and the appearance effect of the glass fiber board can be realized subsequently.
In some embodiments, the adhesive is a resin, and the second refractive index of the resin may be 1.540 to 1.590 according to the composition, so that a glass cloth having a refractive index close to the second refractive index may be used. For example, in one example, the refractive index of the fiberglass cloth is about 1.54, such that a highly transmissive epoxy having a second refractive index of about 1.54 may be used.
It is understood that, in the embodiments of the present disclosure, the adhesive is not limited to the epoxy resin exemplified above, but may be any other adhesive having a transparent property suitable for implementation, and the present disclosure is not limited thereto. In addition, for the preset range of the difference value between the first refractive index and the second refractive index, a person skilled in the art may select the difference value according to specific design requirements, and the disclosure does not limit the difference value.
And S230, laminating and laminating the multiple layers of prepregs and at least one decorative layer to obtain the glass fiber board.
In the embodiment of the present disclosure, based on the foregoing, the prepreg obtained by combining the glass fiber cloth obtained in S220 and the binder has good transparency and a good light transmission effect, so that a decorative layer can be used to provide a rich appearance effect for the glass fiber board.
Specifically, the prepreg obtained in S220 is a single-layer prepreg, and the thickness thereof is generally 0.01mm to 0.1mm, and in the case of a glass fiber board for realizing a back sheet of an electronic device, for example, the thickness may be 0.5mm. Therefore, based on the thickness requirement of the glass fiber plate, a preset number of layers of prepregs can be laminated and pressed.
In the disclosed embodiments, the decorative layer may include one layer or may include multiple layers. In one example, the decorative layer includes one layer, so that a single layer of the decorative layer can be sandwiched between multiple layers of prepreg, or a single layer of the decorative layer can be disposed on outer layers of multiple layers of prepreg, and then the layers are laminated and pressed together to obtain the glass fiber board with decorative appearance effect. In another example, the decorative layer comprises multiple layers, so that the multiple layers of decorative layer can be sequentially and alternately laminated with multiple layers of prepreg, and then the lamination treatment is carried out together to obtain the glass fiber board with multiple composite appearance effects.
In some embodiments, in consideration of the material stability of the glass fiber board, the decorative layer may be made of a material having a better compatibility with the prepreg, so as to avoid affecting the bonding force between the materials of each layer and avoiding the occurrence of a delamination phenomenon. For example, the decorative layer may include, but is not limited to, one or more of a fiberglass felt layer, a flash powder layer, a metal wire layer, an aramid fiber layer, a polyester fiber layer, a plant fiber layer, and an animal fiber layer.
It can be understood that in the embodiment of the disclosure, the prepreg is obtained by using the glass fiber cloth with similar refractive index and the adhesive, so that the transparency of the prepreg is better, when the laminating and pressing are performed, a plurality of decorative layer effects can be arranged between the transparent prepreg layers, and the appearance effect of the glass fiber board is richer. Taking the electronic device back panel as an example, in the related art, since the glass fiber board itself has poor transparency, most of them can only achieve an appearance effect similar to a matte surface, but the embodiment of the present disclosure is not limited thereto.
Therefore, in the embodiment of the disclosure, the appearance effect of the glass fiber board is enriched, and the popularization and application of the glass fiber board in the field of electronic equipment are facilitated.
Fig. 4 illustrates a structure of a glass fiber panel provided in some embodiments of the present disclosure, and the glass fiber panel and a method for manufacturing the same will be described below with reference to fig. 4.
In some embodiments, the glass fiber panel of the disclosed examples includes a plurality of layers of glass fiber substrates 300 and at least one decorative layer 400 in a laminated arrangement. The glass fiber substrate 300 includes at least one prepreg layer 310, and the prepreg layer 310 may be the prepreg obtained by the aforementioned preparation method S220. The decoration layer 400 may be disposed on the middle layer or the outer layer of the multi-layer glass fiber substrate 300.
For example, in the example of fig. 4, the glass fiber board includes two glass fiber substrates 300 and a decoration layer 400, and the decoration layer 400 is sandwiched between the two glass fiber substrates 300. Each glass fiber substrate 300 includes two prepreg layers 310, and the prepreg layers 310 include glass fiber cloth woven by glass fiber yarns 311 and a binder 312 filled in gaps between the glass fiber cloth.
In some embodiments, the decorative layer may include one or more of a fiberglass felt layer, a glitter layer, a wire layer.
Taking the glass fiber plate structure of fig. 4 as an example, a method for manufacturing a glass fiber plate according to an embodiment of the present disclosure will be described below.
As shown in fig. 5, in some embodiments, a method of making a glass fiber sheet, exemplary of the present disclosure, includes:
s501, obtaining glass fiber cloth woven by glass fiber yarns, and impregnating the glass fiber cloth with a binder to obtain a prepreg.
Specifically, the glass fiber cloth is impregnated with a resin to obtain a glass fiber reinforced resin composite material, that is, a prepreg, with reference to S210 to S220.
In one example, the first refractive index of the glass fiber cloth is 1.540, so that the resin binder with the second refractive index of 1.530-1.550 can be selected, and the difference value between the first refractive index of the glass fiber cloth and the second refractive index of the resin binder meets a preset range, so that the obtained prepreg has good transparency.
And S502, obtaining a preset number of layers of prepreg and decoration layers.
Specifically, the prepreg obtained as described above is a single prepreg layer, and the number of layers of the prepreg can be determined according to the thickness of the prepreg layer, the thickness of the decorative layer, and the thickness of the glass fiber plate.
For example, in the example shown in fig. 4, the thicknesses of the single layers of the prepreg layer 310 and the decorative layer 400 are both 0.1mm, and the thickness of the glass fiber plate is required to be 0.5mm, so that 4 layers of the prepreg layer 310 and 1 layer of the decorative layer 400 can be arranged, and the glass fiber plate obtained after the press bonding process is 0.5mm.
S503, arranging a decorative layer on an interlayer of the prepreg with a preset number of layers.
For example, as shown in fig. 4, first, 4 prepreg layers 310 and 1 decorative layer 400 are stacked in the illustrated structure, that is, the decorative layer 400 is provided in the interlayer of the prepreg layers 310.
And S504, laminating and pressing the prepreg and the decoration layer to obtain the glass fiber board.
In some embodiments, all the materials stacked in S503 may be placed in a mold for cold pressing, that is, each layer of prepreg and decoration layer is preformed in the mold by pressure, so as to obtain a preformed board. The preformed sheet is then pressed together using an autoclave molding process to obtain a glass fiber sheet such as that shown in fig. 4.
In some embodiments, before the pre-formed plate is subjected to autoclave forming, the pre-formed plate can be filled into an aluminum foil bag for vacuumizing, so that the temperature and the pressure of an autoclave can be more uniformly applied to the surface of the plate in a vacuum environment, and the plate can be better formed in the vacuum environment.
Therefore, in the embodiment of the disclosure, the appearance effect of the glass fiber board is enriched, and the glass fiber board is beneficial to popularization and application in the field of electronic equipment.
It should be noted that, in the embodiment of the present disclosure, the number of layers of the prepreg layer 310 and the decoration layer 400 in the glass fiber board is not limited, and may be any number suitable for implementation, and may be set by a person skilled in the art according to the needs of a specific scenario.
As shown in fig. 6, for example, in some embodiments, the glass fiber panel includes 4 prepreg layers 310 and 3 decorative layers 400, and the decorative layers 400 are alternately stacked with the prepreg layers 310 in sequence. The process for preparing the glass fiber board is similar to the above process, and can be understood and fully implemented by those skilled in the art with reference to the above process, and the detailed description thereof is omitted.
In the embodiment of fig. 6, different decorative materials may be used for the 3 decorative layers 400, for example, the 3 decorative layers are a colored glass fiber felt layer, a glitter layer, and a metal wire layer. Because the prepreg layer 310 has good transparency, the outer part of the glass fiber board can have the visual effect of compounding color, metal wires and flash powder, the appearance effect of the glass fiber board is greatly enriched, and the appearance texture of the equipment can be effectively improved when the prepreg layer is used for the backboard of the electronic equipment.
Of course, it can be understood by those skilled in the art that the structure of the glass fiber board of the present disclosure is not limited to the above examples, and on the basis of the foregoing embodiment, any other laminated structure suitable for implementation may also be implemented, and details of the present disclosure are not repeated herein.
Therefore, in the embodiment of the disclosure, the appearance effect of the glass fiber board is enriched, and the popularization and application of the glass fiber board in the field of electronic equipment are facilitated.

In some embodiments, taking the preparation of the back sheet 120 of the smart phone shown in fig. 1 as an example, after the fiberglass cloth is impregnated with the binder to obtain the prepreg, the prepreg may be cut, that is, a large block of the prepreg is cut into about 1m by 1m square, which facilitates the subsequent lamination operation. Also, after the stacking process, the stacked materials may be cut according to the size of the back plate 120, and then the cut small materials may be fed into a mold for cold pressing and autoclave molding. This is understood and fully implemented by those skilled in the art, and the present disclosure will not be described in detail herein.
