Abstract

The invention discloses an insensitive taian and a preparation method thereof, in order to solve the problem of low safety performance in the process of the prior art. The insensitive Taian of the present invention is made by covering Taian with a mixture of a thermoplastic elastomer and a flame retardant as a desensitizing agent, and the thermoplastic elastomer is butanediol-succinic acid-adipic acid copolymer, so The flame retardant mentioned above is dioctyl phthalate, and the particle size of said Taian is 50 μm-80 μm. It consists of the following components in mass percentage: 0.5%-10.1% of butanediol-succinic acid-adipic acid copolymer, 0.3%-0.9% of dioctyl phthalate, and 89.1%-98.5% of Taian. The invention effectively reduces the mechanical sensitivity of Taian itself and its flexible explosive, improves the safety performance of the flexible explosive preparation process, does not affect the performance of the original explosive formula, has simple preparation process and low cost, and is suitable for popularization and application in large quantities.

Description

technical field [0001] The invention relates to the field of propellant and explosives, in particular to an insensitive taian and a preparation method thereof. Background technique [0002] Flexible explosive is a kind of mixed explosive that is easy to bend, has rubber-like appearance, small critical diameter and high detonation sensitivity. Due to the characteristics of Taian, it is widely used in the formulation of flexible explosives. However, Taian itself has a high sensitivity, which causes the powders of flexible explosives to collide and rub against each other during the preparation process, causing explosives to burn or even explode. Existing flexible explosives have safety hazards in the process of preparation and operation. In recent years, the application range of flexible explosives in military and civilian products has gradually increased, and the requirements for the safety and reliability of explosive charges have been continuously improved. It is necessary t...
