Abstract
The invention provides a solid gas generator and a preparation method thereof. The solid gas generator comprises 12 to 23% of a polyether adhesive, 1.2 to 3.6% of a curing agent, 50 to 80% of an oxidizing agent, 0 to 5% of a plasticizer, 0 to 30% of a cooling agent, 0 to 5% of a combustion conditioning agent and 0 to 2% of other additives, wherein the polyether adhesive is one or a composition of more than one selected from the group consisting of ethylene oxide tetrahydrofuran copolyether and propylene oxide tetrahydrofuran copolyether, the curing agent is one or a composition of more than one selected from the group consisting of toluene diisocyanate, isophorone diisocyanate and multifunctional aliphatic diisocyanate, and the plasticizer is one or a composition of more than one selected from the group consisting of dioctyl sebacate, acetyl triethyl citrate and triethyl glycerin tricarbonate. The solid gas generator provided by the invention has a negative pressure exponent of 0 to - 0.30 and provides a power source for attitude control and orbit control power systems of light-weight kinetic kill vehicles (KKV).
Description
technical field [0001] The invention relates to a gas generating agent for gas generators and other gas generators, in particular to a negative pressure index type composite solid gas generating agent. Background technique [0002] Space reconnaissance satellites, penetration and anti-penetration of strategic weapons have constituted a non-negligible part of future warfare, and interception weapons play an extremely important role in it. Among interceptor weapons, Kinetic Energy Weapon (KEW) technology has become one of the main driving forces for countries to develop ballistic missile defense systems. The core component of kinetic energy weapons is "kinetic energy kill interceptor" (KKV). At present, the development direction of KKV technology is light weight (second generation technology) and intelligence based on light weight (third generation technology). This trend The gas power source used is required to adopt negative pressure index technology. At present, there is ...
