[0004] To address the aforementioned problems, this utility model provides the following technical solution:

[0005] A rigid composite mobile phone case coating includes two fiberglass cloth layers and several glass bead layers and glass fiber layers.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example

[0028] Reference Figures 1 to 4 This embodiment of the present invention provides a rigid composite mobile phone case coating, comprising two fiberglass cloth layers 100, a plurality of glass bead layers 200, and a glass fiber layer 300. At least two of the glass bead layers 200 and one of the glass fiber layers 300 are disposed between the two fiberglass cloth layers 100. The glass bead layers 200 and the glass fiber layers 300 are interleaved and superimposed, and two of the glass bead layers 200 are respectively located between one of the glass bead layers 200 and one of the glass fiber layers 300.

[0029] Specifically, the fiberglass cloth and fiberglass layer 300 are made of the same material but through different processes. Their physical properties are quite similar, exhibiting excellent tensile and bending resistance. Glass beads possess high hardness and rigidity, providing support within the interlayer and increasing the rigidity of the composite board. Epoxy resin has excellent chemical resistance, resisting the erosion of various chemicals and suitable for harsh environments. Therefore, the fiber composite board made from these three materials is not only simple in composition but also has a relatively simple fiber structure. The low material density of the glass bead layer 200 and fiberglass layer 300 contributes to the overall lightweight of the composite board. Furthermore, the interleaved layering of glass beads 200 and fiberglass layer 300 gives this composite board excellent toughness and strength, while maintaining a very simple structure. Since both glass beads and fiberglass use silica sand as the main raw material, their temperature properties and compressive strength are similar, thus reducing processing requirements and making production easier, thereby improving production yield.

[0030] For example, such as Figure 1 As shown, the thickness of the two fiberglass cloth layers 100 is equal to the thickness of several fiberglass layers 300. The thickness of the two fiberglass cloth layers 100 and the fiberglass layers 300 is between 0.1-0.3mm. The total thickness of the glass bead layer 200 and the fiberglass layer 300 is between 0.5-2mm. According to the standard for mobile phone case thickness, they can be divided into thin cases, ordinary cases, and protective cases. The appropriate thickness is adopted according to the actual situation of the product.

[0031] For example, such as Figure 2 As shown, the number of glass bead layers 200 is between 2 and 4, and the number of glass fiber layers 300 is between 1 and 4, as described above and will not be repeated here.

[0032] For example, such as Figure 3 As shown, the glass bead layer 200 includes an epoxy resin adhesive 201 and glass beads 202. The glass beads 202 are immersed in the epoxy resin adhesive 201. The fiberglass cloth layer 100 is bonded to the glass bead layer 200 and the fiberglass layer 300 through the epoxy resin adhesive 201. The epoxy resin can form a strong bond with the fiberglass, ensuring the overall strength and stability of the composite material. After curing, the epoxy resin has high strength and toughness, can effectively transfer loads, improve the tensile and bending resistance of the composite material, can resist the erosion of various chemicals, and is suitable for various harsh environments. The epoxy resin maintains stable performance over a wide temperature range and is not easily affected by temperature changes, making it suitable for use in different environments.

[0033] For example, such as Figure 4As shown, the glass fiber layer 300 includes a first glass fiber 301, a second glass fiber 302, a third glass fiber 303, and a fourth glass fiber 304. The first glass fiber 301 is bonded to the second glass fiber 302 by an epoxy resin adhesive 201, the second glass fiber 302 is bonded to the third glass fiber 303 by an epoxy resin adhesive 201, and the third glass fiber 303 is bonded to the fourth glass fiber 304 by an epoxy resin adhesive 201. The first glass fiber 301 and the second glass fiber 302 are stacked horizontally and vertically, the second glass fiber 302 and the third glass fiber 303 are stacked horizontally and vertically, and the third glass fiber 303 and the fourth glass fiber 304 are stacked horizontally and vertically. Here, the epoxy resin adhesive 201 is used to further reduce the use of other adhesives, thereby affecting the production of the composite board. At the same time, the interlaced bonding of the glass fibers can improve the toughness of the glass fiber layer 300, and the structure of the glass fiber layer 300 is more robust.

[0034] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible (e.g., changes in the size, dimensions, structure, shape and proportion of various elements, as well as parameter values ​​(e.g., temperature, pressure, etc.), mounting arrangements, use of materials, color, orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application). For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of elements may be inverted or otherwise altered, and the nature or number or position of discrete elements may be changed or altered. Therefore, all such modifications are intended to be included within the scope of this utility model. The order or sequence of any process or method steps may be changed or reordered according to alternative embodiments. In the claims, any "device plus function" clause is intended to cover the structure described herein that performs the function, and not only structural equivalents but also equivalent structures. Without departing from the scope of this invention, other substitutions, modifications, alterations, and omissions may be made in the design, operation, and arrangement of the exemplary embodiments. Therefore, this invention is not limited to the specific embodiments, but extends to various modifications that still fall within the scope of the appended claims.

[0036] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.
