Description
Technical Field
[0001] The present application relates to the technical field of packaging materials, and in particular to a lightweight, high-strength, and corrosion-resistant basalt fiber composite board, a preparation method thereof, and a logistics box prepared using the same. Background Art
[0002] In maritime transport, logistics boxes are an important logistics tool. Their standardization and optimization design are of great significance to improving transportation efficiency and protecting cargo safety. At present, most of the materials used for maritime transport logistics boxes are plastic boards, wooden boards or metal boards. However, plastic boards have low strength and are easy to damage. Although the strength of wooden boards and metal boards meets the requirements of use, they are prone to corrosion, causing great economic losses to the country every year. Lightweight design and enhanced corrosion resistance have become important development trends. By adopting new materials and structural designs, reducing the weight of logistics boxes and improving their carrying capacity and service life has become the future development direction of logistics boxes.
[0003] Existing logistics boxes are composed of six boxes, namely, a bottom plate, four side plates around the box, and a cover plate. The edges of the adjacent boxes are connected to each other by traditional mechanical connection methods. The commonly used connection method is to connect with nails or screws, which is time-consuming to disassemble and easily damages the connection parts. Therefore, it is particularly important to solve the above problems. Summary of the invention
[0004] In order to solve the above technical problems, the present application provides a lightweight, high-strength, and corrosion-resistant basalt fiber composite board, a preparation method thereof, and a logistics box prepared using the same.
[0005] The present application provides a basalt fiber composite board, which specifically includes the following components in parts by weight: 4-8 parts of silicone resin, 30-40 parts of boron-modified phenolic resin, 160-200 parts of basalt fiber, 3-9 parts of foaming agent, and 5-15 parts of modified polyurethane; the silicone resin is selected from one or more of SH-9501 silicone resin, SH-023 silicone resin, SH-5202S silicone resin, and SH-024 silicone resin.

[0007] The combination of silicone resin and boron-modified phenolic resin provides basalt fiber composite panels with excellent high temperature resistance and mechanical strength; the flexibility and weather resistance of silicone resin, coupled with the hardness and stability of boron-modified phenolic resin, enable the composite panels to maintain structural integrity and stability under different environments. The addition of foaming agent significantly reduces the density of the composite panels, achieving lightweight and easy installation and transportation. The introduction of modified polyurethane enhances the chemical corrosion resistance and wear resistance of the composite panels, which enables basalt fiber composite panels to be used for a long time in harsh chemical environments and withstand frequent friction and impact. The basalt fiber composite panels prepared using the above raw materials not only have excellent performance, but also meet the requirements of environmental protection and sustainability.
