Description

Technical Field

[0001] The utility model relates to the technical field of plate strengthening, in particular to a bendable explosion-proof acrylic plate sandwich strengthening component. Background Art

[0002] Acrylic plates (polymethyl methacrylate) are widely used due to their high transparency and good processing performance. However, traditional acrylic plates have deficiencies in impact resistance and explosion-proof performance. In some special scenarios, such as chemical workshops, flammable and explosive places, security equipment, etc., plates that are bendable, explosion-proof, and have high strength are required. Currently, to solve the explosion-proof and impact resistance problems, the current market often adopts strengthening means such as increasing the thickness of the acrylic plate or compounding glass fiber.

[0003] Although the existing technology can improve the explosion-proof and impact resistance capabilities to a certain extent, it significantly increases the weight of the plate. At the same time, the increase in thickness easily affects the flexibility of the plate, making it rigid and difficult to bend. For special-shaped windows that need to be bent for installation, curved decorations and other scenarios, the construction requirements cannot be met.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a bendable explosion-proof acrylic plate sandwich strengthening component is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a bendable explosion-proof acrylic plate sandwich strengthening component to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A bendable explosion-proof acrylic plate sandwich strengthening component, including an explosion-proof sandwich layer and an elastic buffer layer I. The explosion-proof sandwich layer includes a fiber mesh, silicone elastic glue, a sealing strip, and a frame. The pores of the fiber mesh are filled with silicone elastic glue. A sealing strip is arranged at the edge of the fiber mesh, and a frame is arranged outside the sealing strip. The top of the explosion-proof sandwich layer is connected to an upper acrylic plate through an adhesive layer I, and the bottom of the explosion-proof sandwich layer is connected to a lower acrylic plate through an adhesive layer II. The elastic buffer layer I is arranged on the upper surface of the upper acrylic plate, and an anti-slip pattern I is arranged on the upper surface of the elastic buffer layer I.

[0007] Further, the warp and weft density of the fiber mesh is 100 mesh, and the thickness of the fiber mesh is 0.8 mm.

[0008] Further, the sealing strip is embedded in the inner groove of the frame, and the cross-section of the frame is U-shaped.

[0009] Further, the frame has a "hui" - shaped structure, and the frame is in close contact with both the upper acrylic plate and the lower acrylic plate.

[0010] Furthermore, the lower surface of the lower acrylic sheet is provided with an elastic buffer layer two, and the lower surface of the elastic buffer layer two is provided with anti-slip texture two.

[0011] Furthermore, the first elastic buffer layer and the second elastic buffer layer are 0.8 mm thick, and the first elastic buffer layer and the second elastic buffer layer are symmetrically distributed about the explosion-proof interlayer.

[0012] This utility model provides a flexible explosion-proof acrylic sheet sandwich reinforcement component, which has the following beneficial effects:

[0013] 1. The first and second elastic buffer layers of this utility model are made of EVA (ethylene-vinyl acetate copolymer) material, and the surfaces are respectively provided with anti-slip texture one and anti-slip texture two, which can increase friction and play a buffering role when subjected to impact, further improving the overall impact resistance. The first and second adhesive layers are made of polyurethane adhesive with a working temperature range of -40℃ to 80℃, which can ensure stable connection of each layer in different environments.

[0014] 2. The fiber mesh of this utility model is woven from 1414D aramid yarn with a warp and weft density of 100 mesh, a tensile strength ≥3200MPa, and an elongation ≤3%. It features high strength and lightweight, and can withstand huge tensile forces. The silicone elastic adhesive 102 is a room temperature curing type (RTV-2) with a Shore hardness of A50. The silicone elastic adhesive is filled into the pores of the fiber mesh. After curing, it forms a composite structure with the fiber mesh, which can effectively prevent the board from breaking into fragments when subjected to impact or explosion pressure. The frame is made of aluminum alloy material. The sealing strip is bonded with structural adhesive and wraps the edge of the fiber mesh. This not only enhances the explosion-proof performance of the component, but also effectively prevents moisture, dust and other substances in the external environment from entering the interlayer space, avoids aging or deterioration of the materials in the interlayer, and extends the service life of the component.

[0018] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0019] like Figure 1 As shown, a flexible explosion-proof acrylic sheet sandwich reinforcement assembly includes an explosion-proof sandwich layer 1 and an elastic buffer layer 6. The top of the explosion-proof sandwich layer 1 is connected to an upper acrylic sheet 4 via an adhesive layer 2. The frame 104 has a "U"-shaped structure and is tightly fitted to both the upper acrylic sheet 4 and the lower acrylic sheet 5. The bottom of the explosion-proof sandwich layer 1 is connected to the lower acrylic sheet 5 via an adhesive layer 3. The elastic buffer layer 6 is disposed on the upper surface of the upper acrylic sheet 4, and the upper surface of the elastic buffer layer 6 is provided with anti-slip texture 7. The lower surface of the lower acrylic sheet 5 is provided with an elastic buffer layer 8, and the lower surface of the elastic buffer layer 8 is provided with anti-slip texture 9. The thickness of the elastic buffer layer 6 and the elastic buffer layer 8 is 0.8 mm, and the elastic buffer layer 6 and the elastic buffer layer 8 are symmetrically distributed about the explosion-proof sandwich layer 1.

[0020] The specific operation is as follows: Elastic buffer layer 1 (6) and elastic buffer layer 2 (8) are made of EVA (ethylene-vinyl acetate copolymer) material, and anti-slip texture 1 (7) and anti-slip texture 2 (9) are respectively set on the surface, which can increase friction and play a buffering role when subjected to impact, further improving the overall impact resistance. Adhesive layer 1 (2) and adhesive layer 2 (3) are made of polyurethane adhesive with a working temperature range of -40℃ to 80℃, which can ensure stable connection of each layer in different environments.

[0021] like Figure 2 As shown, the explosion-proof interlayer 1 includes a fiber mesh 101, silicone elastic adhesive 102, sealing strip 103, and frame 104. The pores of the fiber mesh 101 are filled with silicone elastic adhesive 102. A sealing strip 103 is provided at the edge of the fiber mesh 101, and a frame 104 is provided outside the sealing strip 103. The warp and weft density of the fiber mesh 101 is 100 mesh, and the thickness of the fiber mesh 101 is 0.8 mm. The sealing strip 103 is embedded in the inner groove of the frame 104, and the cross-section of the frame 104 is U-shaped.

[0022] The specific operation is as follows: the fiber mesh 101 is woven with 1414D aramid yarn, with a warp and weft density of 100 mesh, a tensile strength ≥3200MPa, and an elongation ≤3%. It has the characteristics of high strength and lightweight, and can withstand huge tensile forces. The silicone elastic adhesive 102 is a room temperature curing type (RTV-2) with a Shore hardness of A50. The silicone elastic adhesive 102 is filled into the pores of the fiber mesh 101. After curing, it forms a composite structure with the fiber mesh 101, which can effectively prevent the board from breaking into fragments when subjected to impact or explosion pressure. The frame 104 is made of aluminum alloy material. The sealing strip 103 is bonded with structural adhesive and the edge of the fiber mesh 101 is wrapped. This not only enhances the explosion-proof performance of the component, but also effectively prevents moisture, dust and other substances in the external environment from entering the interlayer space, avoids aging or deterioration of the materials in the interlayer, and extends the service life of the component.

[0023] In summary, this flexible explosion-proof acrylic sheet sandwich reinforcement assembly, when in use, consists of an upper acrylic sheet 4, an explosion-proof sandwich layer 1, a lower acrylic sheet 5, and upper and lower surface elastic buffer layers 6 and 8, which are tightly bonded by adhesive layers 2 and 3. The 100-mesh aramid fiber mesh 101 in the explosion-proof sandwich layer 1 is filled with silicone elastic adhesive 102 to form a high-strength flexible structure. The edges are sealed by a U-shaped aluminum alloy frame 104 and a sealing strip 103, which can prevent moisture, dust, corrosive gases, etc. from the external environment from entering the sandwich space, while enhancing the overall explosion-proof performance of the assembly.

[0024] When the component is subjected to external impact, the elastic buffer layer 1 6 and the elastic buffer layer 2 8 preferentially contact the external force. The anti-slip texture 1 7 and the anti-slip texture 2 9 on the surface increase the contact area with the impacting object and disperse the impact force. At the moment of force, the elastic buffer layer 1 6 and the elastic buffer layer 2 8 absorb part of the energy through their own elastic deformation, converting the impact force into their own elastic potential energy, and slowing down the speed and intensity of the impact energy being transmitted to the interior.

[0025] After initial stress relief by elastic buffer layer 6 and elastic buffer layer 8, the energy is transferred to the upper acrylic sheet 4 and the lower acrylic sheet 5. The acrylic sheet itself has a certain degree of toughness, which can diffuse the received stress within the sheet, avoiding stress concentration at a certain point and making the impact force more evenly distributed across the entire sheet. When the impact force is transferred to the fiber mesh 101, the fiber mesh 101 disperses the impact force throughout the entire network structure, preventing excessive local stress from damaging the sheet. Due to the good elasticity and adhesion of the silicone elastic adhesive 102, fragments are prevented from flying, significantly improving safety.

[0026] Since the upper acrylic sheet 4 and the lower acrylic sheet 5 are made of high-purity polymethyl methacrylate material, they have a certain degree of flexibility. During the production process, the acrylic sheet is pre-stretched, and with the flexible design of the explosion-proof interlayer 1, as well as the elastic buffer layer 1 and the elastic buffer layer 2 8, the interlayer reinforcement component has good bendability.

[0027] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
