PHLEGMATISED EXPLOSIVE AND METHOD FOR DRY PHLEGMATISATION THEREOF Russian patent published in 2014 - IPC C06B21/00 

FIELD: chemistry.

SUBSTANCE: invention relates to the technology of phlegmatising explosives for use in making pressed charge for the munitions-filling and oil industry, particularly perforation cumulative charges and other special charges used at high temperatures. The phlegmatised explosive is based on a phlegmatising agent made from high-melting polyethylene wax PV-200 with melting point of 103-110°C with addition of stearine and plasticiser DOA (di-(2-ethylhexyl)-adipate). The explosive used is, for example, hexogene or oxtogene. The method for dry phlegmatisation of the explosive by vibration mixing is carried out while heating all components to the melting point of the phlegmatising agent, followed by cooling the mixture of explosive crystals coated with the phlegmatising agent to temperature of 20-60°C.

EFFECT: invention enables to exclude water and drying from the phlegmatisation process, which considerably simplifies the process, and obtain a phlegmatised explosive with high thermodynamic stability and improved processing characteristics - packed density and mouldability.
