Abstract

The invention belongs to the technical field of packaging and transportation, and particularly relates to a modified composite reinforcing material and an antibacterial wear-resistant light tray. Themodified composite reinforcing material comprises the following components in parts by weight: 50-75 parts of methyl hydroxyl silicone oil, 10-35 parts of nano zinc oxide powder and 1-10 parts of chitosan micro powder. The antibacterial wear-resistant light tray comprises a foam inner core and a polyurea coating layer, wherein the polyurea coating layer coats the outer surface of the foam inner core, the foam inner core comprises a supporting plate and supporting legs located below the supporting plate, and the polyurea coating layer is made of an antibacterial wear-resistant polyurea elastomer coating material. The modified composite reinforcing material is adopted, a tray coating layer material component system is optimized, a spraying process is combined, and the impact-resistant, antibacterial and wear-resistant light tray is obtained.

Description

technical field [0001] The invention belongs to the technical field of packaging and transportation, and in particular relates to a modified composite reinforcing material and an antibacterial and wear-resistant light pallet. Background technique [0002] Pallets are load-carrying devices for cargo assembly, stacking and transportation. It is convenient for loading and unloading, handling unit materials and small quantities of material pallets. It plays a considerable role in protecting products and facilitating storage and transportation. It can be said that pallets are the development of modern logistics industry. essential tool. At first, most pallets used wood as the main material, but with the reduction of wood resources, the stringent requirements of international trade on wooden pallets, the standardization of pallets and the acceleration of the development of pallet sharing systems, iron pallets, plastic pallets and paper pallets began to be used. been used on a lar...
