Problems solved by technology

The wood packaging materials used at home and abroad are mainly pine wood. After the pine wood is felled, it has to go through steps such as drying, processing, installation, and finishing. The main problems of wood are the long processing cycle, non-fireproof, non-waterproof, and fear of insects and other shortcomings; Steel packaging is heavy, afraid of impact, and poor in radiation protection

Abstract

The invention provides a military ammunition can material and a preparation method thereof. The military ammunition can material is formed by mixing a long glass fiber composite material and a short glass fiber composite material. The long glass fiber composite material is prepared by the following raw materials, by weight: 30-40 parts of first homopolymerization PP, 50-60 parts of glass fibers, and 8-12 parts of a first compatilizer. The short glass fiber composite material is prepared by the following raw materials, by weight: 35-45 parts of first homopolymerization PP, 15-22 parts of copolymerization PP, 8-12 parts of HIPS, 8-12 parts of glass fibers, 11-13 parts of a toughening agent, 5-8 parts of a second compatilizer, 0.2-0.3 part of an anti-aging agent, 0.5-2 parts of a pigment, 0.5-1 part of a lubricant, and 0.5-1 part of an antistatic agent. A composite material with excellent comprehensive mechanical properties and corrosion resistance, aging resistance, cold resistance and antistatic properties which can meet requirements of military ammunition cans is obtained by mixing the long glass fiber composite material and the short glass fiber composite material.

Description

technical field [0001] The invention belongs to the technical field of military ammunition boxes, and in particular relates to a military ammunition box material and a preparation method thereof. Background technique [0002] The current packaging materials for shells are mainly wood and metal. As the battlefield situation changes, the first two materials have exposed various defects. The wood packaging materials used at home and abroad are mainly pine wood. After the pine wood is felled, it has to go through steps such as drying, processing, installation, and finishing. The main problems of wood are the long processing cycle, non-fireproof, non-waterproof, and fear of insects and other shortcomings; Steel packaging is heavy, afraid of impact, and poor in radiation protection. With the development of science and technology, the application of electronic technology, especially microelectronic technology and computer technology in various shells, has made shells develop from ...
