Description

Technical Field

[0001] This utility model relates to the field of fiberglass molded plates, and in particular to lightweight, impact-resistant and corrosion-resistant fiberglass molded plates. Background Technology

[0002] Lightweight, impact-resistant, and corrosion-resistant materials have wide applications in modern industry, especially in chemical equipment, transportation, construction, and marine engineering. These materials not only need to meet the requirements of high strength and corrosion resistance, but also need to be lightweight to meet the demands for lightweight equipment and energy conservation. Furthermore, the increasing diversity of environmental conditions (such as high humidity, strong ultraviolet radiation, and high or low temperature environments) places higher demands on the comprehensive performance of materials. However, solutions that simultaneously achieve lightweight, impact resistance, corrosion resistance, and long-term stability are relatively scarce among traditional materials, making it difficult to fully meet the needs of complex operating conditions.

[0003] Most existing fiberglass molded sheet materials use conventional resin and ordinary glass fiber reinforcement structures. While they possess some corrosion resistance, their weather resistance and impact resistance are relatively insufficient. For example, traditional materials are prone to aging and cracking under long-term ultraviolet radiation, and their impact resistance is easily compromised under dynamic loads or sudden impacts. Furthermore, during the manufacturing process, uneven resin impregnation or low fiber alignment precision can easily lead to porosity and microcracks, which can cause corrosive media to penetrate and accelerate material degradation. Therefore, developing a lightweight, high-strength fiberglass molded sheet that remains stable and reliable under harsh corrosive environments and dynamic impact loads has become an urgent technical challenge. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide lightweight, impact-resistant, and corrosion-resistant fiberglass molded plates.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lightweight, impact-resistant, and corrosion-resistant fiberglass molded plate, comprising: a corrosion-resistant structure, wherein a coating layer is provided on one outer wall of the corrosion-resistant structure, and an impact-resistant structure is connected to the side of the corrosion-resistant structure away from the coating layer;

[0006] A corrosion-resistant structure includes a corrosion-resistant layer disposed on the outer wall of one side of a coating layer, an additive body disposed on the corrosion-resistant layer, and a fiber layer fixedly connected to one side of the inner wall of the corrosion-resistant layer.

[0007] In a preferred embodiment, the impact-resistant structure includes a buffer layer, and a sandwich layer is fixedly connected to one side of the inner wall of the buffer layer.

[0008] In a preferred embodiment, the inner wall of the buffer layer is provided with a plurality of interlayers, which are arranged in a hexagonal honeycomb pattern.

[0009] In a preferred embodiment, the corrosion-resistant layer is made of a corrosion-resistant resin, such as vinyl ester resin or bisphenol A epoxy resin.

[0010] In a preferred embodiment, the additive body is made of UV-resistant additive, which is uniformly mixed with the corrosion-resistant layer.

[0011] In a preferred embodiment, the fiber layer is made of high-strength and high-modulus fibers, such as aramid fibers, carbon fibers, or S-glass fibers.

[0012] In a preferred embodiment, the buffer layer uses a more resilient resin, such as modified epoxy resin or polyurethane resin.

[0013] In a preferred embodiment, the buffer layer adopts a sandwich structure design, with a sandwich layer sandwiched between two high-strength buffer layer panels, and the sandwich layer uses a lightweight core material.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In use, this invention enhances the material's weather resistance through a corrosion-resistant layer composed of high-performance resins (such as vinyl ester resin and bisphenol A type epoxy resin) and the use of UV-resistant additives. Furthermore, the wear-resistant and corrosion-resistant coating on the outer wall further improves the material's corrosion resistance, while the addition of high-strength, high-modulus fibers (such as aramid fibers, carbon fibers, or S-glass fibers) significantly improves the material's overall strength and toughness. Moreover, the use of a vacuum-assisted resin transfer molding process ensures that the resin fully impregnates the fibers, reducing the material's porosity and minimizing the possibility of corrosive media penetration.

[0016] 2. When in use, this utility model effectively absorbs impact energy and enhances impact resistance by combining a buffer layer made of high-toughness resin (such as modified epoxy resin or polyurethane resin) with a lightweight honeycomb structure core material. The use of automated layup technology ensures the precise arrangement of the sandwich structure, and the combination of hot pressing molding process improves the density and consistency of the material, so that the material can maintain high stability and reliability under complex corrosive environments and dynamic impact loads.

[0031] Example 1

[0032] like Figure 1-4 As shown, this utility model provides a technical solution: a lightweight, impact-resistant, and corrosion-resistant fiberglass molded plate, comprising: a corrosion-resistant structure 1, a coating layer 2 on one side of the outer wall of the corrosion-resistant structure 1, and an impact-resistant structure 3 connected to the side of the corrosion-resistant structure 1 away from the coating layer 2.

[0033] The corrosion-resistant structure 1 includes a corrosion-resistant layer 11 disposed on the outer wall of one side of the coating layer 2. The corrosion-resistant layer 11 is made of corrosion-resistant resin, such as vinyl ester resin, bisphenol A type epoxy resin, etc. An additive body 12 is disposed on the corrosion-resistant layer 11. The additive body 12 is made of UV-resistant additive and is uniformly mixed with the corrosion-resistant layer 11. A fiber layer 13 is fixedly connected to one side of the inner wall of the corrosion-resistant layer 11. The fiber layer 13 is made of high-strength and high-modulus fibers, such as aramid fiber, carbon fiber or S-glass fiber.

[0034] In this embodiment, a corrosion-resistant structure 1 is designed, which includes a corrosion-resistant layer 11. The corrosion-resistant layer 11 is made of a resin with high corrosion resistance, such as vinyl ester resin or bisphenol A epoxy resin. These resins have excellent stability in corrosive environments such as acids, alkalis, and salts. An additive body 12 is added to the corrosion-resistant layer 11. The additive body 12 is an anti-ultraviolet additive to improve the weather resistance of the material in outdoor environments and reduce the damage of ultraviolet rays to the material. Furthermore, a fiber layer 13 is sandwiched between the corrosion-resistant layer 11 and the additive body 12. The fiber layer 13 is made of high-strength and high-modulus fibers, such as aramid fibers, carbon fibers, or S-glass fibers. These materials have excellent impact resistance, which can significantly improve the strength and toughness of composite materials. A coating layer 2 is provided on one side of the outer wall of the corrosion-resistant layer 11. The coating layer 2 has wear-resistant and corrosion-resistant properties, which can significantly improve the corrosion resistance. The corrosion-resistant structure 1 adopts a vacuum-assisted resin transfer molding process. This process can ensure that the resin is completely impregnated between the fibers, reduce porosity, reduce the penetration of corrosive media, and further ensure the corrosion resistance and impact resistance of the plate.

[0035] Example 2

[0036] like Figure 1-2 As shown in Figure 5, the impact-resistant structure 3 includes a buffer layer 31. The buffer layer 31 uses a resin with higher toughness, such as modified epoxy resin or polyurethane resin. A sandwich layer 32 is fixedly connected to one side of the inner wall of the buffer layer 31. The inner wall of the buffer layer 31 is provided with several sandwich layers 32. The sandwich layers 32 are arranged in a hexagonal honeycomb pattern. The buffer layer 31 adopts a sandwich layer 32 structure design, in which a sandwich layer 32 is sandwiched between two high-strength buffer layer 31 panels. The sandwich layer 32 uses a lightweight core material.

[0037] In this embodiment, an impact-resistant structure 3 is provided, which includes a buffer layer 31. The buffer layer 31 uses a resin with higher toughness, such as modified epoxy resin or polyurethane resin. These resins can absorb more impact energy and reduce the possibility of material fracture. A sandwich structure 32 is designed in the middle of the buffer layer 31, with a sandwich layer 32 sandwiched between two high-strength buffer layer 31 panels. The sandwich layer 32 uses a lightweight core material, which is hexagonal and has a honeycomb structure evenly distributed on one side of the middle of the buffer layer 31. This structure can effectively absorb impact energy and provide better impact resistance. The impact-resistant structure 3 adopts automated lay-up and hot-pressing processes. The automated lay-up technology ensures that the sandwich layer 32 can be accurately arranged and laid on one side of the middle of the buffer layer 31 to improve material consistency and impact resistance. The hot-pressing process can improve the density and consistency of the material, reduce defects, and improve impact resistance.

[0038] Working principle:

[0039] like Figure 1-5 As shown, the composite material design achieves excellent corrosion resistance and impact resistance through the synergistic effect of corrosion-resistant structure 1 and impact-resistant structure 3, combined with multilayer composite material design and advanced manufacturing processes. The corrosion-resistant structure 1 utilizes high-performance resins (such as vinyl ester resin and bisphenol A epoxy resin) to form a corrosion-resistant layer 11, with added UV-resistant additives to enhance the material's weather resistance. Simultaneously, the addition of high-strength, high-modulus fibers (such as aramid fiber, carbon fiber, or S-glass fiber) improves the material's strength and toughness. Furthermore, a wear-resistant and corrosion-resistant coating is added to the outer wall to further enhance its corrosion resistance. A vacuum-assisted resin transfer molding process is employed to ensure complete resin impregnation of the fibers, reducing porosity and minimizing the penetration of corrosive media. The impact-resistant structure 3 uses high-toughness resins (such as modified epoxy resin or polyurethane resin) to form a buffer layer 31. Combined with a sandwich design 32, a lightweight honeycomb core material is embedded in the center of the buffer layer 31 to effectively absorb impact energy and enhance impact resistance. Automated layup technology ensures the precise arrangement of the sandwich layer 32, and hot pressing is used to improve the material's density and consistency, thereby further enhancing its overall performance. The overall design enables the material to maintain high stability and reliability under complex corrosive environments and dynamic impact loads, meeting the needs of various engineering applications.
