Embodiment 1

[0042] (1) Composition of gas generating agent

[0043]

[0044] (2) Performance of gas generating agent

[0045]

[0046] The preparation process of Example 1 is as follows: weigh each component in the formula according to the proportion, and after premixing the liquid component and the small component, add the solid component and the curing agent to the vertical mixer in sequence for mixing, and the mixing temperature is 50°C ~70℃, mixing time 60min~100min. Vacuum spray pour the slurry into the mold or into the engine, and then put it in an oil bath oven at 50°C to 70°C to cure for 7 days.

Abstract

The invention discloses a clean composite solid gas generator which comprises the following components by mass: 10%-20% of an adhesive; 1%-5% of a curing agent, 50%-80% of an oxidant, 0%-15% of a cooling agent; 5%-15% of a plasticizer; 0%-5% of a combustion regulator and 0%-2% of an additive. The clean composite solid gas generator has the advantages of low content of gas residue, cleaness, no acid, simple main raw material synthesis, low cost, and the like, and can provide gas for a precise gas actuator or a full gas servo mechanism.

Description

technical field [0001] The invention relates to a gas generating agent for gas generators and other gas generators, especially a clean composite solid gas generating agent. Background technique [0002] The gas generating agent is the power source for auxiliary control power devices in aviation, spaceflight and missile technology. Ammonium perchlorate (AP) is the most widely used gas generator oxidant at present, which has the advantages of low hygroscopicity, high energy, good high / low temperature ignition performance, and low minimum pressure for stable combustion, but it will produce a lot of smoke in the gas particles and contains HCl corrosive gas. On the one hand, it will cause strong erosion, corrosion and even blockage of turbine blades or gas generator pipelines. Therefore, for precision gas steering gears, small-caliber nozzles and parts that work for a long time and are used repeatedly, it is required to use a gas generator with low residue content, smokeless ga...
