Description

Technical Field

[0001] This invention relates to the field of acrylic glass processing technology, and in particular to an acrylic glass splicing structure and composite sheet. Background Technology

[0002] Polymethyl methacrylate (PMMA), also known as plexiglass, is a transparent polymer material with excellent comprehensive performance, widely used in traffic noise barriers, transparent buildings, thermal insulation curtain walls, and aircraft windows. For large-scale PMMA-based ornamental or landmark buildings, there is often a combination and splicing of different pieces. In this process, the common existing technology uses adhesives to bond the edges of the plexiglass to the surfaces of adjacent plexiglass blocks, forming an interconnected structure. Once the adhesive has cured, it can be put into use.

[0003] However, the aforementioned existing technologies are only applicable to non-structural stress-bearing locations. In structural stress-bearing areas that play a major supporting role, the small contact area of ​​the adhesive layers in the surface-to-surface bonding makes the bonding area prone to bending, breakage, and other phenomena, resulting in insufficient reliability and certain safety hazards. Utility Model Content

[0004] The purpose of this application is to provide an acrylic splicing structure and composite board, which aims to solve the problem that spliced ​​composite boards obtained based on existing technology are prone to bending and breaking due to insufficient adhesive layer strength.

[0005] To achieve the above objectives, this application provides an acrylic splicing structure, including a base, a support member, and a liquid material. The base has a receiving groove, the support member is disposed on the receiving groove, the support member is used to abut against the acrylic to be spliced, and the liquid material is used to inject into the receiving groove to fix the receiving groove and the acrylic.

[0006] Optionally, the receiving groove includes a groove bottom and a groove wall, wherein the groove bottom and the groove wall have the same shape.

[0007] Optionally, the bottom of the tank and the tank wall have different shapes; the bottom of the tank is planar, and the tank wall is serrated or zigzag.

[0008] Optionally, the support member is disposed on the bottom of the groove and abuts against the groove wall.

[0009] Optionally, there are multiple support members, which are spaced apart from each other along the length of the receiving groove to form two rows of support rails. The support rails are disposed on the bottom of the groove and abut against the groove wall.

[0010] Optionally, the number of the support members is two, the two support members are disposed on the bottom of the groove and respectively abut against the adjacent groove wall, and the length of the support member is equal to the length of the receiving groove.

[0011] Optionally, the support member is disposed on the bottom of the groove along the centerline of the groove bottom.

[0012] Optionally, the number of the support members is one, and the length of the support member is equal to the length of the receiving groove.

[0013] Optionally, there are multiple support members, and the multiple support members are spaced apart from each other along the length direction of the receiving groove.

[0014] This application also provides a composite sheet material, including plexiglass and the plexiglass splicing structure as described above, wherein the plexiglass is disposed in the receiving groove and forms a cavity with the support member for injecting the liquid phase material; wherein the length of the plexiglass is less than the length of the receiving groove, and the width of the plexiglass is less than the width of the receiving groove.

[0015] This application sets up a base with a receiving groove, and then sets up a support member in the receiving groove to support the acrylic glass to be spliced. When the acrylic glass is placed in the receiving groove, liquid material is injected into the receiving groove to fix the acrylic glass in the receiving groove. In this way, due to the increase in the connection surface area between the acrylic glass and the base, the overall structural strength of the acrylic glass and the stress reliability in the width direction are improved, and the safety is significantly improved.

[0028] Please refer to Figure 1 , Figure 1An exploded view of an acrylic glass splicing structure is shown, including a base 1, a support member 2, and a liquid material (not shown). The base 1 has a receiving groove 12, and the support member 2 is disposed inside the receiving groove 12, serving to support the acrylic glass 3 to be spliced. The liquid material (not shown) is injected into the receiving groove 12 to fix the receiving groove 12 and the acrylic glass 3. Specifically, in this embodiment, the base 1 has a receiving groove 12 with a preset depth, width, and length. The support member 2 is disposed inside the receiving groove 12, and when the end of the acrylic glass 3 is placed in the receiving groove 12, the support member 2 serves to support the acrylic glass 3. Then, by injecting the liquid material (not shown) into the receiving groove 12, and after the liquid material (not shown) solidifies, the acrylic glass 3 and the base 1 are fixed. Thus, due to the increased connecting surface area between the acrylic glass 3 and the base 1 (compared to the prior art, the two inner sidewalls of the receiving groove 12 constitute the newly added bonding area), the overall structural strength of the acrylic glass 3 and its stress reliability in the sectional direction are improved, significantly enhancing safety. The width of the receiving groove 12 is preferably 100-800 mm, the depth is preferably 100-500 mm, and the length is set according to actual needs.

[0029] Optionally, the main body material of the base 1 is an acrylic polymer, such as polymethyl methacrylate, polyacrylic acid, a copolymer modified from polymethyl methacrylate, or a copolymer modified from polyacrylic acid. The receiving groove 12 can be opened by machining, or it can be formed in advance by using a mold during the molding process of the base 1, which is not limited here.

[0030] Optionally, the support member 2 can be made of metal or the same material as the base 1. The liquid phase material (not shown in the figure) can be a liquid adhesive, preferably a mixture of MMA prepolymer liquid and room temperature initiator. In the illustrated structure, the cross-section of the support member 2 is circular. It is understood that the cross-section of the support member 2 can also be triangular, elliptical, square, rectangular, etc., and is not limited to this.

[0031] Please refer to Figure 2The receiving groove 12 includes a groove bottom 121 and a groove wall 122, and the groove bottom 121 and the groove wall 122 have the same shape. Specifically, in this embodiment, the receiving groove 12 is composed of a groove bottom 121 and a groove wall 122, and both have the same shape. For example, the groove bottom 121 and the groove wall 122 can be planar, wavy, arc-shaped, sawtooth-shaped, or zigzag-shaped, etc., and are not limited here. By setting the groove bottom 121 and the groove wall 122 to have the same shape, after curing, the stress can be distributed more evenly throughout the entire structure of the receiving groove 12, and the occurrence of stress concentration areas can be avoided as much as possible, thereby improving the overall strength and durability of the connection structure. Preferably, both the groove bottom 121 and the groove wall 122 are planar, and the cross-section of the receiving groove 12 forms a rectangle as shown in the figure.

[0032] Please refer to Figure 3 The bottom 121 and the wall 122 of the tank have different shapes; the bottom 121 is planar, while the wall 122 is serrated. Figure 3 (b) or broken line shape ( Figure 3 (c) Specifically, in this embodiment, the bottom 121 of the groove is planar, and the groove wall 122 is formed in a sawtooth shape. Figure 3 (b) or broken line shape ( Figure 3 (c) By setting the tank wall 122 to a non-linear shape such as a sawtooth or zigzag shape, a larger contact surface area can be obtained between the plexiglass 3 and the liquid phase material (not shown in the figure), thereby achieving better reliability in subsequent use.

[0033] Optionally, the support member 2 is disposed on the bottom 121 of the tank and abuts against the tank wall 122. Specifically, in this embodiment, the support member 2 is disposed at the junction between the tank wall 122 and the bottom 121 of the tank, that is, the bottom surface of the support member 2 is disposed on the bottom 121 of the tank, and one side abuts against the tank wall 122. In this way, by disposing of the support member 2 at the bottom edge of the receiving tank 12, when the liquid phase material (not shown in the figure) is injected into the receiving tank 12, the central end face of the plexiglass 3 can better bond with the liquid phase material (not shown in the figure), thereby improving the connection strength.

[0034] Please refer to Figure 2There are two support members 2, which are disposed on the bottom 121 of the trough and abut against the adjacent trough walls 122. The length of the support member 2 is equal to the length of the receiving trough 12. Specifically, in this embodiment, the two support members 2 are respectively disposed on both sides of the receiving trough 12, with their bottom surfaces disposed on the bottom 121 of the receiving trough 12 and one side abutting against the trough wall 122. It can be understood that since the length of the support member 2 is equal to the length of the receiving trough 12, the shape of the two support members 2 is elongated. In this way, the two support members 2 are used to support the plexiglass 3. When the liquid material (not shown in the figure) is injected into the receiving trough 12, the liquid material (not shown in the figure) will fill all areas outside the two support members 2, and then, after sufficient curing, it will effectively bond with the end face of the plexiglass 3, thereby improving the connection strength.

[0035] Optionally, there are multiple support members 2, which are spaced apart along the length of the receiving groove 12 to form two rows of support tracks. The support tracks are set on the bottom 121 of the groove and abut against the groove wall 122. Specifically, in this embodiment, multiple support members 2 are arranged at intervals along the length of the receiving groove 12 at the edge of the receiving groove 12, that is, the bottom surface of each support member 2 is set on the bottom 121 of the receiving groove 12, and one side abuts against the groove wall 122, forming two rows of support tracks in a long strip shape. In this way, the two rows of support tracks are used to support the plexiglass 3 as a whole. Since there is a gap between each support member 2, when liquid material (not shown in the figure) is injected into the receiving groove 12, the liquid material (not shown in the figure) will fill the space between each two support members 2, and then effectively bond with the plexiglass 3 after sufficient curing, thereby improving the connection strength.

[0036] Please refer to Figure 4 The support member 2 is positioned on the bottom of the groove 121 along the centerline of the groove bottom 121. Specifically, in this embodiment, the user can set the position of the support member 2 according to the length of the acrylic glass 3. For example, when the width of the acrylic glass 3 is the same, for a longer acrylic glass 3, the user can choose to position the support member 2 along the length direction of the groove bottom 121 on the centerline of the groove bottom 121. Conversely, for a shorter acrylic glass 3, the user can choose to position the support member 2 along the width direction of the groove bottom 121 on the centerline of the groove bottom 121, which is not limited here. In this way, by setting the support member 2 only on the centerline of the receiving groove 12, it is possible to ensure that the acrylic glass 3 provides good support. When the liquid phase material (not shown in the figure) is injected into the receiving groove 12, the liquid phase material (not shown in the figure) will fill all areas except for the support member 2, and then effectively bond with the acrylic glass 3 after sufficient curing, thereby improving the connection strength.

[0037] Optionally, the number of support members 2 is one, and the length of the support member 2 is equal to the length of the receiving groove 12. Specifically, in this embodiment, the support member 2 is set on the bottom 121 along the centerline of the groove bottom 121, and the number of support members 2 is one. The length of the support member 2 is also equal to the length of the receiving groove 12, that is, the shape of the support member 2 is elongated. In this way, by setting the support member 2 only on the centerline of the receiving groove 12, it can ensure that the plexiglass 3 can be well supported. When the liquid material (not shown in the figure) is injected into the receiving groove 12, the liquid material (not shown in the figure) will fill all areas except for the support member 2, and then effectively bond with the plexiglass 3 after sufficient curing, thereby improving the connection strength.

[0038] Optionally, there are multiple support members 2, which are spaced apart from each other along the length of the receiving groove 12. Specifically, in this embodiment, based on the support members 2 being arranged along the centerline of the groove bottom 121 on the groove bottom 121, there are multiple support members 2, which are spaced apart from each other. In this way, the whole formed by the multiple support members 2 is used to support the plexiglass 3. Due to the gap between each support member 2, when the liquid phase material (not shown in the figure) is injected into the receiving groove 12, the liquid phase material (not shown in the figure) will also fill the space between every two support members 2, and then, after sufficient curing, it will effectively bond with the plexiglass 3, thereby improving the connection strength.

[0039] Please refer to Figure 5 The figure shows a cross-sectional view of a composite panel, which includes acrylic glass 3 and the acrylic glass splicing structure described above. The acrylic glass 3 is disposed within a receiving groove 12 and forms a cavity with the support member 2 for injecting liquid material 6. Specifically, in this embodiment, the length of the acrylic glass 3 is less than the length of the receiving groove 12, and the width of the acrylic glass 3 is less than the width of the receiving groove 12. The main body of the acrylic glass 3 is embedded in the receiving groove 12 to abut against the pre-embedded support member 2, forming a cavity with it for injecting liquid material 6. Thus, by injecting liquid material 6 into the receiving groove 12 and then curing the liquid material 6, effective fixation between the acrylic glass 3 and the base 1 is achieved.

[0040] In this process, after the liquid material 6 enters the mold cavity, it can wet and dissolve the surfaces of the support 2, base 1, and acrylic glass 3 to a certain extent. After initial curing and the material losing its fluidity, a longer post-curing period is then implemented, typically overnight at room temperature. Afterward, the user can decide whether a second high-temperature annealing treatment is necessary based on the performance requirements of the application scenario. Thus, during the formation of the potting adhesive layer, the phase interfaces of the support 2, base 1, and acrylic glass 3 gradually dissolve and disappear. As the curing reaction proceeds, they continuously form interconnections, ultimately connecting into a single unit.

[0041] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
