Description

Technical Field

[0001] This utility model relates to the field of plastic products technology, and in particular to a high-transparency polycarbonate sheet for use in industrial protective windows. Background Technology

[0002] Polycarbonate, as a high-performance engineering plastic, has been widely used in the field of industrial protection due to its unique physical and chemical properties. Compared with glass, polycarbonate has an impact strength that is more than 200 times higher, which can effectively resist physical impacts and provide better safety protection. It is also much lighter than glass, which helps to reduce the overall structural weight. In the application of existing polycarbonate sheets, high light transmittance is achieved by reducing the thickness of the sheet body.

[0003] For example, Chinese patent application number CN202022971858.6 discloses a high-transmittance safety board, including a substrate layer. Above the substrate layer, from bottom to top, are sequentially arranged a first adhesive layer, a buffer layer, a printed pattern layer, a second adhesive layer, and a transparent protective layer. The transparent protective layer is made of polycarbonate and is composed of the buffer layer, substrate layer, printed pattern, and transparent protective layer, ensuring the strength and light transmittance of the entire board while reducing the overall thickness, thus achieving the characteristics of high light transmittance and safety. However, when applied to protective windows, it will inevitably be subjected to certain impacts during industrial production. Its lightweight and impact-resistant properties due to its single-layer solid structure still need improvement. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a high-transparency polycarbonate sheet for industrial protective windows, in order to solve the technical problem that when existing technology is applied to protective windows, they will inevitably be subjected to certain impacts during industrial production processes, and the lightweight and impact resistance of their single-layer solid structure still need to be improved.

[0005] To achieve the above objectives, this utility model provides a high-transparency polycarbonate sheet for industrial protective windows, comprising a substrate layer made of polymethyl methacrylate, a transparent protective layer made of polycarbonate on the side of the substrate layer, the substrate layer and the transparent protective layer being bonded together with epoxy resin adhesive, the central part of the substrate layer having a double-layer cavity structure with internal pores, and the high-transparency polycarbonate sheet further comprising:

[0006] E-shaped structures are provided on the left and right edges of the substrate layer;

[0007] The splicing portions are located on the upper and lower sides of the substrate layer;

[0008] Adjustment portions are respectively provided on both sides of the substrate layer and the transparent protective layer.

[0009] Furthermore, the splicing part includes protrusions and grooves respectively provided on the upper and lower edges of the substrate layer, with the protrusions fitting into the grooves.

[0010] Furthermore, the outer surface of the transparent protective layer is provided with a UV coating.

[0011] Furthermore, the adjustment part includes a fixed rail and an adjustment rail. The fixed rail has a mounting hole, and the adjustment rail can be adjusted and installed on the fixed rail through the mounting hole. An U-shaped connecting strip is installed on the other side of the adjustment rail. One side of the E-shaped structure of the substrate layer and the transparent protective layer are respectively engaged with the inner side of the connecting strip.

[0012] Furthermore, the connecting strip has sealing blocks at both ends, which cooperate with the air holes.

[0013] Furthermore, the enclosed block contains a replaceable desiccant pack.

[0014] Furthermore, the pores are arranged in a through-hole configuration, and the spacing between adjacent pores is 5 times the pore diameter.

[0015] Furthermore, the thickness of the substrate layer is 5 mm, and the thickness of the transparent protective layer is 1 mm.

[0016] The beneficial effects of this utility model are as follows: In use, the splicing part completes the splicing of each polycarbonate sheet in the protective window, and the adjustment part adjusts the protective height of the substrate layer with transparent protective layer in the protective window. Since the middle part of the substrate layer in the high-transparency polycarbonate sheet has a double-layer cavity structure, the cavity structure combined with the thin wall setting ensures the overall strength while achieving lightweight, and can form a certain buffering effect in the protective window.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0027] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar words used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0028] The first aspect of this utility model proposes a high-transparency polycarbonate sheet material for use in industrial protective windows, such as... Figures 1-6 As shown, the material includes a substrate layer 1 made of polymethyl methacrylate, a transparent protective layer 2 made of polycarbonate on the side of the substrate layer 1, and the substrate layer 1 and the transparent protective layer 2 are bonded together with epoxy resin adhesive. The center of the substrate layer 1 has a double-layer cavity structure with pores 3 inside. The high-transparency polycarbonate sheet also includes:

[0029] E-shaped structures 4 are located on the left and right edges of the substrate layer 1;

[0030] The splicing parts are located on the upper and lower sides of the substrate layer 1;

[0031] Adjustment sections are respectively provided on both sides of the substrate layer 1 and the transparent protective layer 2.

[0032] In this embodiment, when used as a protective window, the transparent protective layer 2 faces the industrial production environment. The splicing part completes the splicing of each polycarbonate sheet in the protective window. At the same time, the adjustment part adjusts the protective height of the substrate layer 1 with the transparent protective layer 2 in the protective window. Since the middle of the substrate layer 1 in the high-transparency polycarbonate sheet is a double-cavity structure, the cavity structure combined with the thin wall setting ensures the overall strength while achieving lightweight. If production sputtering causes an impact on the transparent protective layer 2, the substrate layer 1, through the E-shaped structure 4, combined with the adjustment part, can form a certain buffering effect in the protective window.

[0033] In this embodiment, as Figure 1 , Figure 4 , Figure 5 , Figure 6 As shown, the splicing part includes a protrusion 5 and a groove 6 respectively provided on the upper and lower edges of the substrate layer 1. The protrusion 5 is inserted into the groove 6. By inserting the protrusion 5 on the upper side of one substrate layer 1 into the groove 6 on the lower side of another substrate layer 1, the splicing is convenient and reliable.

[0034] In this embodiment, as Figure 1 , Figure 3 As shown, the outer surface of the transparent protective layer 2 is coated with a UV coating to prevent yellowing under prolonged high-temperature conditions and to ensure high light transmittance.

[0035] In this embodiment, as Figure 1 , Figure 2 As shown, the adjustment part includes a fixed rail 7 and an adjustment rail 8. The fixed rail 7 has a mounting hole 9. The adjustment rail 8 can be adjusted and installed on the fixed rail 7 through the mounting hole 9. A U-shaped connecting strip 10 is installed on the other side of the adjustment rail 8. One side of the E-shaped structure 4 of the substrate layer 1 and the transparent protective layer 2 are respectively engaged with the inner side of the connecting strip 10.

[0036] In this embodiment, as Figure 2 As shown, the two ends of the connecting strip 10 are provided with sealing blocks 11. The sealing blocks 11 cooperate with the air holes 3. The sealing blocks 11 contain replaceable desiccant packs. The mist that may be generated in the cavity of the substrate layer 1 due to temperature difference will be discharged into the sealing blocks 11 through the air holes 3. And by replacing the desiccant packs in the sealing blocks 11, the accumulation of condensate in the board can be avoided.

[0037] In this embodiment, as Figure 3 As shown, the vent 3 is a through-hole design, and the spacing between adjacent vent 3 is 5 times the vent diameter, ensuring that any moisture that may be present inside can flow smoothly and further reducing the risk of condensation.

[0038] In this embodiment, the thickness of the substrate layer 1 is 5mm and the thickness of the transparent protective layer 2 is 1mm, which ensures structural strength while achieving high transparency and lightweight effect.
