Abstract

The invention discloses an artificial composite tray for logistics and a preparation method thereof, the artificial composite tray for logistics comprises a tray surface and at least four circular-truncated-cone-shaped hollow bottom feet, the tray surface is integrally pressed and formed, the bottom feet protrude towards the same side of the tray surface, and a fork hole is formed between every two adjacent bottom feet; edge ribs protruding towards the same side of the disc face are pressed on the peripheral edge of the disc face. According to the artificial composite tray for logistics, crushed materials of waste materials such as straw, wood chips and saw dust and modified urea-formaldehyde resin glue are pressed, cured, heated and shaped to be integrally formed, and the strength and stability of the tray are guaranteed; meanwhile, local materials can be used, waste such as straw is effectively utilized, and the manufacturing cost of the tray is reduced. A certain amount of free urea is formed in the adhesive, so that the free urea captures and absorbs free formaldehyde existing in adhesive preparation and formaldehyde released during thermocuring of the composite tray, emission of harmful gas in production and use is greatly captured and eliminated, and the adhesive becomes an environment-friendly product.

Description

technical field [0001] The invention relates to the technical field of logistics products, in particular to an artificial composite tray for logistics and a preparation method thereof. Background technique [0002] With the development of loading and unloading and transportation equipment, the degree of mechanization of loading and unloading operations in the logistics field is getting higher and higher. The items to be transported need to be placed on suitable pallets for mechanical loading and unloading, and the use of pallets is increasing. At present, pallets are usually made of plastic or disposable wooden pallets, and the production cost is high. Since most items flow in one direction, after arriving at the receiving place, the pallet takes up a large area and the transportation cost is high. Abandoned or damaged, resulting in a great waste of resources. Contents of the invention [0003] The purpose of the present invention is to provide a man-made composite pallet...
