Abstract

The invention provides an adhesive system suitable for insensitive munitions and a preparation method. The adhesive system is prepared by, by weight, 40-50 parts of polyol, 30-60 parts of energetic plasticizer, 5-10 parts of polyisocyanate, 0.0002-0.001 part of catalyst. During preparation, raw material preprocessing including the rotary evaporation dewatering of the polyol and the energetic plasticizer and raw material preheating is performed during preparation, the polyol and the energetic plasticizer are then premixed, and a curing agent is added finally and sufficient and uniform mixing isperformed to perform curing at 55-65 DEG C for 4-7 days. Compared with a traditional hydroxyl-terminated polybutadiene-based (HTPB-based) adhesive system, the adhesive system is high in oxygen content, good in compatibility with the energetic plasticizer, and capable of evidently increasing the energy output of an explosive system; the adhesive system is mild in reaction under a heat stimulationcondition and melts and expand when being heated to break through a munition shell, explosion possibility under the heat stimulation condition is lowered, and munition insensitivity is increased.

Description

technical field

[0001] The invention belongs to the technical field of cast PBX explosives and insensitive ammunition, and in particular relates to a binder system suitable for insensitive ammunition and a preparation method thereof. Background technique

[0002] The modern battlefield environment is deteriorating day by day, and major accidental safety accidents caused by the vulnerability of the ammunition system itself have brought a heavy price to people. The research on high-energy and insensitive ammunition technology is the key to improving the survivability of the ammunition battlefield. Since the early 1970s, the United States took the lead in proposing the concept of insensitive ammunition, successively developed a variety of insensitive ammunition such as PBXN-109, PBXN-110, and PBXN-129, and formulated the military standard for insensitive ammunition MIL- STD-2105C, for assessing the safety and hazards of munitions. At the same time, NATO has also formulated the...
