Abstract

The invention belongs to the technical field of material and transport, and relates to a composite material for a container base plate and a preparation method thereof. The composite material is a sandwich structure, and comprises a core layer and cover panels covering on upper and lower surfaces of the core layer, wherein the core layer is glass-felt-reinforced thermoplastic composite panel, the cover panels are thermoplastic resin and fiber reinforced thermoplastic sheets made from fibers. The composite material can reasonably select thickness and density of the covering surfaces and core materials according to actual needs, so as to reach optimum economic and weight-loss effects. The composite material is good in wear resistance, corrosion resistance, non-absorbent, and easy to clean; and compared with hardwood base plates, is greatly improved in service life. In addition, the composite material base plate is prepared all by fibers and plastic, free of corrosion and bacteria, and not damaged by insects; during preparation, no adhesive is used, and no formaldehyde is released, and thus the material is completely harmless, green and environmentally protective.

Description

technical field [0001] The invention belongs to the technical field of materials and transportation, and relates to a composite material for a container bottom plate and a preparation method thereof. Background technique [0002] At present, cargo transportation all over the world is developing towards containerization. Container bottom plates have high technical requirements for strength, rigidity, wear resistance, and water resistance. Therefore, since the birth of container transportation in the past few decades, container bottom plates have almost entirely relied on high-density hard broads grown in tropical rainforests. Leaf wood is made by compounding multiple layers. These hardwoods are mainly imported from Southeast Asia. Due to the long growth cycle of hardwoods, and with the global protection of the environment and climate, and the increasing emphasis on maintaining the ecological environment, some countries have begun to restrict the felling and export of these h...
