Description

Technical Field

[0001] This utility model relates to a composite board, specifically an environmentally friendly polymer composite board, belonging to the field of polymer composite material technology. Background Technology

[0002] Polymer composite panels are high-performance boards made by combining polymer resins with reinforcing materials such as fibers and particles. They combine the corrosion resistance and easy processing properties of polymer materials with the high strength and high modulus advantages of reinforcing materials, making polymer composite panels widely used in decoration and structural fields.

[0003] A thermal insulation polymer composite board disclosed in Chinese Patent Application Publication CN214606264U includes a main body with a cavity inside. A sealing plate is fixedly connected to the top of the main body, and a groove is formed on the top of the sealing plate. A vent pipe is formed at the bottom of the groove, and a high-strength elastic block is fixedly connected to the bottom of the sealing plate. By employing the above technical solution, through the design of the sealing plate, the high-strength elastic block, and the load-bearing substrate, the device has excellent compressive strength and can absorb and buffer the impact force, thereby greatly reducing the occurrence of [damage / damage]. The reduced probability of deformation and breakage makes this device more durable. The design of the vent pipe and silica gel drying granules provides excellent moisture resistance, effectively drying any moisture entering the board and keeping its interior dry. This prevents moisture from reducing the board's insulation performance and improves the device's practicality. However, the aforementioned technical solution relies on solvent-based adhesives for interlayer bonding, resulting in excessive VOC emissions. The interlayer bonding is irreversible, making it impossible to disassemble and separate after disposal. Furthermore, the polymer materials and functional fillers are mixed together, leading to low recycling rates, resource waste, and environmental pollution.

[0004] Therefore, an environmentally friendly polymer composite board is proposed here. Utility Model Content

Meanwhile, the hot melt block 303 can be manually fed into the hidden grooves 5 corresponding to both ends of the positioning rod 302 by using a hot melt gun. The cooling and solidification of the hot melt block 303 can facilitate the limiting of both ends of the positioning rod 302. This can improve the connection stability of the environmentally friendly polymer composite board and facilitate the disassembly and assembly of the polymer composite board, thereby improving the environmental performance of the polymer composite board. Simultaneously, when installing the connecting plate 204, the rectangular sealing strip 7 between the two connecting plates 204 can be engaged with the rectangular sealing groove 6 opened on the inner wall of the limiting groove 203 to form a rectangular seal, thereby improving the assembly sealing performance of the polymer composite board.
