Abstract

The invention discloses a plastic-dipped electrode product for an electric-control solid propellant and a preparation method thereof. The plastic-dipped electrode product comprises the following raw materials by weight: 50 to 100 parts of film-forming resin, 10 to 30 parts of a plasticizer, 5 to 10 parts of an inorganic filling material, 0 to 10 parts of an organic filling material, 1 to 5 parts of a coupling agent, 20 to 80 parts of a mixed solvent, 2 to 8 parts of a dispersing agent, 1 to 3 parts of a leveling agent and 3 to 8 parts of an antifoaming agent. The preparation method comprises the following steps: preparing a plastic dipping solution from the above components; dipping an electrode matrix in the plastic dipping solution for 1 to 60 s and then taking out the electrode matrix for drying at 50 to 120 DEG C for 2 to 24 h; then carrying out plasticization at 150 to 350 DEG C for 5 to 30 min; and carrying out normal-temperature cooling so as to prepare the plastic-dipped electrode product with high temperature resistance, strong acid corrosion resistance and good adhesion. The plastic-dipped electrode product prepared by using the method has high insulating properties, good impact resistance, good matrix adhesion, good strong acid resistance and heat resistance.

Description

technical field [0001] The invention relates to the field of plastic dipping products, in particular to a plastic dipping product of an electrically controlled solid propellant electrode and a preparation method thereof. Background technique [0002] Electronically controlled solid propellant is a new type of energetic material that can only continue to burn when it is energized. Because it can ignite multiple times, it is not sensitive to impact, high-temperature flames, and electrostatic induction; the energy is controllable and easy to operate and maintain; the combustion products are harmful to The environment is pollution-free, the preparation process is simple, and the operation safety has attracted much attention. [0003] figure 1 It is a schematic diagram of an electronically controlled propellant device. There is a layer of high-temperature-resistant coating on the center electrode except for the front end. The exposed part of the front end of the center electrode...
