Abstract

The invention discloses an insulating material with high temperature resistance and strong acid corrosion resistance for an electric control solid propellant electrode. The insulating material is characterized by being prepared from the following components in parts by weight: 30 to 60 parts of polytetrafluoroethylene suspension, 20 to 30 parts of epoxy resin, 5 to 10 parts of polyvinyl alcohol, 0 to 20 parts of polyphenylene sulfide, 0 to 20 parts of polyimide, 1 to 2 parts of nano titanium dioxide, 0.5 to 2 parts of super-fine calcium carbonate, 1 to 3 parts of molybdenum disulfide, 2 to 5 parts of magnesium hydroxide, 0.5 to 3 parts of oxidized polyethlene wax, 0.5 to 1 part of stearic acid, 2 to 3 parts of n-octanol, 1 to 2 parts of titanate coupling agent, 0.5 to 1 part of levelling agent and 2 to 3 parts of curing agent. The material can resist instant high temperature and strong acid corrosion, is low in preparation and spraying cost and has a certain adhesive force.

Description

technical field [0001] The invention relates to the field of materials, in particular to a high-temperature-resistant and strong-acid-resistant insulating material for electrically controlled solid propellant electrodes. Background technique [0002] Insulating materials are based on high molecular polymers, which are solidified into insulating films under certain conditions, and are generally composed of high molecular resins, additives and other main materials. [0003] Electronically controlled solid propellant is a new type of energetic material that releases a large amount of gas when it is energized and burned. An insulating layer is attached to one electrode to prevent the propellant from detaching from the propulsion device when it is energized and burned. It is also resistant to strong acid corrosion and The role of high temperature resistance. [0004] figure 1 It is a schematic diagram of the electronically controlled solid propellant combustion process, represe...
