Problems solved by technology

Wooden ammunition boxes have sufficient toughness, but their disadvantages are that the preparation process is complicated, they are fragile under impact, they do not have flame retardancy, and they are easy to rot during long-term storage and transportation.
Steel ammunition boxes have problems such as being too bulky, poor in flexibility, prone to friction and sparks, difficult to make special-shaped products, and difficult to recycle and reuse.

Description

technical field [0001] The invention belongs to the technical field of special chemical materials, and in particular relates to a glass fiber reinforced polyurethane foam material for military ammunition boxes and a preparation method thereof. Background technique [0002] During military exercises, marching training, etc., it is often necessary to transport various ammunition equipment of different weights and sizes, especially large artillery shells. In order to ensure the absolute safety of the transportation and storage process, the requirements for storing and transporting ammunition boxes are often very high. Military ammunition boxes often need to have a very high load-carrying capacity to carry heavy ammunition; a certain degree of toughness is required to prevent dangerous situations such as fragmentation of the ammunition box and friction of shells caused by bumps during storage and transportation; certain water resistance and water resistance are required. High t...
