Embodiment 1

[0011] This embodiment is carried out with reference to the following mass percentage composition: 98% mixed crystal (68.6% FOX-7, 29.4% RDX) and 2% butyl acrylate-acrylonitrile copolymer emulsion.

[0012] Preparation of this example: Take the preparation of 1000g of explosives as an example, weigh 980g of mixed crystal material and put it into 2000ml of water, weigh the emulsion and pour it into water, stir for 5-10 minutes to form a suspension, and prepare anhydrous sulfuric acid with a concentration of 10%. Sodium solution, add water after it is completely dissolved, add a small amount of ethyl acetate, heat up to 55°C-60°C, stir for 0.5 hours, discharge, rinse with 20°C water repeatedly three times, and pass through a 10-mesh sieve at the same time; The booster powder granules are placed in an oven at a temperature of 60° C. to 65° C. for 5 hours, and the booster powder is obtained after discharging. Accurately weighed and pressed into shape by the constant volume method,...

Embodiment 2

[0014] This embodiment is carried out with reference to the following mass percentage composition: 98% mixed crystal (63.6% FOX-7, 34.4% RDX) and 2% butyl acrylate-acrylonitrile copolymer emulsion. The preparation method of this embodiment refers to embodiment 1.

Abstract

The invention discloses a high-energy pressure-loaded and insensitive booster explosive and a preparation method, and aims to solve the problems that the urgent application demand of current insensitive ammunition has to be met and the existing cyclonite booster explosives cannot meet the insensitive technical requirement. The booster explosive is prepared from, a mixed-crystalline composite material (comprising 1, 1-diamino-2, 2-dinitroethylene and cyclonite) and a binder, and the booster explosive is prepared from moulding powder through an emulsion method. The high-energy pressure-loaded and insensitive booster explosive has the advantages of high-density, high detonation speed, high safety and low cost (simple process, and easy amplification), the insensitive requirement is also met, and the comprehensive performance is excellent. The booster explosive is mainly used for safety detonation of all kinds of explosive charges.

Description

technical field [0001] The invention relates to a high-energy press-packed insensitive booster charge and a preparation method thereof, which are mainly used for detonating various types of blasting equipment. Background technique [0002] The problem of secondary disasters caused by the reaction of explosives under unexpected stimuli has attracted the attention of countries all over the world. In order to ensure the safety of personnel and property, foreign countries took the lead in proposing the development of insensitive ammunition technology, and insensitive energetic materials (including boosters, main explosives, propellants and pyrotechnic charges) are at the heart of achieving insensitive ammunition. [0003] The main function of the booster is to initiate the main charge. Typical foreign boosters are PBX9407, PBXN-6, and TR series, but none of these boosters can meet the insensitivity requirements. In order to meet this requirement, foreign countries mainly develo...
