Description
Technical field
The present invention generally belongs to propellant technical field, uses more particularly to a kind of solid propellant rocket motor charge
Solid propellant.
Background technique
The features such as HTPB propellant is because of its high comprehensive performance, moderate cost, becomes in domestic and international solid propellant rocket
Most widely used propellant kind, the dominant position in missile armament.But since HTPB adhesive itself is that one kind is free of
Can substance can not be more compatible with the energetic plasticisers such as nitrate and since its polarity is smaller, constrain its energy characteristics into one
Step improves.In addition, its molten liquid mobility is poor due to fourth hydroxyl adhesive, occur when can not fill up ammonium perchlorate low-temperature decomposition
Hole causes HTPB propellant that can generate violent detonation response in slow cook-off test, can not be tested by slow cook-off,
Therefore HTPB propellant is also unable to satisfy the requirement of Low vulnerability.
As the continuous development of China's tactical missile weapon is started to further increase the long-range strike ability of weapon
Machine requires to further increase to the energy characteristics of propellant, and existing HTPB Propellant warp is unable to satisfy engine technology
Index request, therefore polyethers (code name NEPE) propellant of nitrate plasticising is applied in certain key strategy models, but
High production cost, the risk of NEPE high-energy propellant are larger, constrain its extensive application in tactical weapon model.Cause
This, in domestic and international weapon system still based on HTPB propellant.
In addition, the adhesive due to NEPE propellant is polyethers, the molten liquid of polyethers adhesive is had preferable mobility,
Therefore NEPE high-energy propellant can be tested by slow cook-off, but due to containing a large amount of explosive in NEPE propellant, quick-fried
It is easy to happen detonation under fried shock wave, therefore NEPE propellant is also unable to satisfy the requirement of Low vulnerability.
In order to improve the energy characteristics of HTPB propellant, while improving the low vulnerability of propellant, it can be by polyethers and fourth
Hydroxyl glue is made into block copolymer.The polarity of adhesive not only can be improved in the introducing of polyethers section, to solve HTPB adhesive and nitre
The consistency problem of the energetic plasticisers such as acid esters makes energetic plasticiser be applied in HTPB propellant, to improve propulsion
The energy characteristics of agent；The introducing of polyethers section can also improve the mobility of adhesive molten liquid, this is beneficial to polyethers-fourth hydroxyl
Block polymer is that the propellant of adhesive is tested by slow cook-off, to meet the requirement of propellant low vulnerability.

The patent mainly describes solidification, aging, degradation property and and the energetic plasticiser of this kind block polymer film
Plasticising performance, be not directed to using fourth hydroxyl-polyether block polymer as items such as the mechanics of the propellant of adhesive, technique, energy
Performance.
A kind of polyethers-fourth hydroxyl block polymer, the structure of polymer such as II institute of formula is synthesized by two-step process in China Zhang Chunsen
Show.
A in formula II is polyethers section
The purpose that Zhang Chunsen synthesizes the block polymer is to improve polyurethane adhesive water resistance, therefore it is in text
In only describe the thermal decomposition characteristic of block polymer and the mechanical property of film, be not applied in solid propellant.
Zhang Wanbin is for the first time using HTPB as macromole evocating agent, under lewis acidic catalytic action, utilizes the activity of HTPB
End group causes tetrahydrofuran ring opening polymerization, prepares polytetrahydrofuran-polybutadiene-polytetrahydrofuran triblock copolymer.It is poly-
The structure of object is closed as shown in formula III.
