Problems solved by technology

However, traditional non-metallic packaging materials such as fibers, cloth, and polymer materials cannot meet the aforementioned key requirements, and the biggest difficulty at this stage is that the compatibility between packaging materials and propellants cannot be controlled at level 1, and it is even more difficult to Control the surface resistivity at a relatively good level (10 9 ~10 10 Ω)

Abstract

The invention provides a propellant packaging material and a preparation method thereof, the propellant packaging material comprises the following raw materials by weight: 1-6 parts of carbon nanotube, 0.1-0.6 part of dispersant, and the balance of linear low density polyethylene resin; the preparation method comprises the following steps: weighing the carbon nano tube, the dispersing agent and the linear low-density polyethylene resin, and mixing the carbon nano tube and the dispersing agent to obtain a mixture I; adding linear low-density polyethylene resin into the mixture I, and uniformly mixing through a high-speed mixer to obtain a mixture II; and adding the obtained mixture II into a double-screw extruder, and carrying out blending and extrusion granulation to obtain the plastic particles. The invention provides a brand new scheme in which the modified plastic is directly used as a propellant packaging material, and the compatibility of the packaging material and the propellant reaches the level 1 by using a small amount of additive.

Description

technical field [0001] The invention belongs to the technical field of propellant packaging materials, in particular to a propellant packaging material and a preparation method thereof. Background technique [0002] Propellant is the power source and power source for launching, driving, and destroying various weapons and equipment. It is a basic strategic material for national defense. In order to cope with the suddenness of war, propellant needs to be safely stored in peacetime, and products are required to be reliable in wartime. The propellant is a kind of solid energetic material with its own oxidative and combustible components, and has a certain shape, which is extremely sensitive, so it has extremely strict requirements for the storage and transportation of the propellant. The static electricity generated by friction during storage and transportation will cause the propellant to burn and explode, and the propellant is prone to chemical reactions with the packaging mat...
