Description

Technical Field

[0001] This utility model relates to the technical field of outdoor corn stalk-based co-extruded wall panels, specifically an outdoor corn stalk-based co-extruded wall panel with waterproof and flame-retardant functions. Background Technology

[0002] With increasing societal focus on environmental protection and sustainable development, the search for new green building materials has become a crucial direction for the construction industry. Traditional building wall panel materials, such as bricks, concrete, and metal panels, often consume significant amounts of natural resources and energy during production, potentially leading to environmental pollution. Meanwhile, while some organic panels offer advantages like lightweight, they suffer from shortcomings in waterproofing, flame retardancy, and durability. Corn stalks, as a rich source of agricultural waste, not being effectively utilized not only wastes resources but also risks environmental pollution and greenhouse gas emissions due to improper disposal methods such as incineration. Applying corn stalks to building wall panels offers numerous potential advantages, including low cost, renewability, lightweight, and certain thermal insulation properties, aligning with the principles of energy conservation, emission reduction, and resource recycling.

[0003] In the process of developing this utility model, the inventors discovered the following problems with the existing technology: 1. Common outdoor corn stalk-based co-extruded wall panels may not have corresponding waterproof and flame-retardant functions. Prolonged water exposure will reduce the protective effect of the co-extruded wall panels, causing them to fall off and potentially leading to fires, thus increasing the risk; 2. Common outdoor corn stalk-based co-extruded wall panels may not be quick to install. It is necessary to drill holes in the co-extruded wall panels and then use fixing bolts to install them, which reduces the overall installation efficiency, increases the labor force of workers, and also increases time costs. Utility Model Content

[0004] The purpose of this utility model is to provide an outdoor corn stalk-based co-extruded wall panel with waterproof and flame-retardant functions to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: an outdoor corn stalk-based co-extruded wall panel with waterproof and flame-retardant functions, comprising a main wall panel, a first insertion block installed at one end of the main wall panel, first connecting blocks fixedly connected to both sides of the first insertion block, and a second insertion block installed at the other end of the main wall panel, with second connecting blocks fixedly connected to both sides of the second insertion block.

[0005] The main wall panel includes a substrate, the substrate is covered with a waterproof barrier layer, and the waterproof barrier layer is covered with a flame-retardant protective layer.

[0006] More preferably, threaded slots are provided on both sides of one end of the first connecting block and the second connecting block.

[0007] More preferably, one end of the main wall panel is configured as an insertion shape, and the other end of the main wall panel is configured as a plug-in shape, and the main wall panel is provided with multiple such plug-in shapes.

[0008] More preferably, the corners of the main wall panel are rounded.

[0009] More preferably, the waterproof barrier layer is made of polyethylene waterproof membrane.

[0010] More preferably, the flame-retardant protective layer is made of flame-retardant polypropylene.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In this invention, a waterproof barrier layer and a flame-retardant protective layer are added, which makes the co-extruded wall panel with corn stalk as the base material not only have basic strength and heat insulation performance, but also increase waterproofness and flame retardancy. This effectively avoids the substrate from rotting and becoming moldy due to moisture, effectively improves protection, and can also effectively prevent the spread of flames, reducing the possibility of fire causing casualties.

[0013] In this invention, the two sides of the main wall panel are respectively designed as insertion and plug-in, which allows multiple main wall panels to be quickly connected without the need for drilling holes on the surface of the main wall panel for fixing, thus ensuring the integrity of the main wall panel. Furthermore, the rounded corner design effectively avoids accidental injury during connection, increasing safety and improving work efficiency. Attached Figure Description

[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, threaded slots are provided on both sides of one end of the first connecting block 3 and the second connecting block 5. This design allows the first plug-in block 2 and the second plug-in block 4 to be fixedly installed on both sides of the installation position, thereby enabling effective co-extruded wall panel butt installation and ensuring that the edge of the main wall panel 1 is also effectively protected.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, one end of the main wall panel 1 is designed to be inserted, and the other end of the main wall panel 1 is designed to be plugged in. There are multiple main wall panels 1. This design allows multiple main wall panels 1 to be quickly connected, thereby effectively improving work efficiency. There is no need to drill holes on the surface of the main wall panel 1 for fixing, thus ensuring the integrity of the main wall panel 1 and effectively improving the subsequent protection of the main wall panel 1.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the corners of the main wall panel 1 are rounded. This design effectively reduces the risk of significant damage to workers during the handling and installation of the main wall panel 1, thereby improving worker safety.

[0025] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the waterproof barrier layer 102 is made of polyethylene waterproof membrane. Through this design, it is wrapped around the outside of the substrate 101 by co-extrusion process, which can effectively prevent moisture from penetrating into the substrate 101 and prevent the substrate 101 from getting damp and rotting and moldy. This effectively improves the waterproof performance and does not affect the processing and installation performance of the main wall panel 1.

[0027] The usage and advantages of this utility model: The outdoor corn stalk-based co-extruded wall panel with waterproof and flame-retardant functions operates as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the substrate 101 is first produced using a co-extrusion process. A waterproof barrier layer 102 is then attached to the outside of the substrate 101, giving the main wall panel 1 waterproof properties and effectively preventing moisture from penetrating into the substrate 101 and causing it to rot and mold. Then, a flame-retardant protective layer 103 is wrapped around the outer layer of the waterproof barrier layer 102, giving the main wall panel 1 flame-retardant properties and effectively preventing the spread of fire. When installation is required, the fixing bolts are installed into the first insertion block 2 through the threaded slots in the first connecting block 3. Then, one end of the main wall panel 1 is inserted into the first insertion block 2. The other end of the main wall panel 1 is then inserted into the first insertion block 2, and so on. After the installation of the last main wall panel 1 is completed, the fixing bolts are then installed into the second insertion block 4 from the outside through the threaded slots in the second connecting block 5, thus completing the overall installation.
