Abstract

The invention discloses RDX-based network explosive ink and a preparation method thereof, wherein the raw materials comprise, by weight, 82-86 parts of RDX explosive, 6-8.5 parts of a high-strength adhesive, 6-8 parts of a high-toughness adhesive, 0.5-0.8 part of a sensitivity reducing agent and 0.03-0.05 part of a surfactant. According to the invention, the obtained RDX-based network explosive can be used as ink for direct writing or printing, and the automatic charging of an explosion network can be realized by adopting the ink, so that the charging precision and the charging efficiency areimproved.

Description

technical field [0001] The invention belongs to the field of energetic materials, and in particular relates to an RDX-based network explosive ink and a preparation method thereof. Background technique [0002] Network explosives are a type of explosives used to explode network charges. The RDX-based explosive formulation is the most widely used network explosive at present. It has the advantages of low critical explosion size, strong environmental adaptability, and good safety performance. However, the existing RDX-based network explosive formulations are mainly charged by manual extrusion or manual scraping. It is difficult to greatly improve the charging accuracy and the charging efficiency is low. The main reason is that the process performance of the existing RDX network explosive formulations is difficult to meet. Automated charging needs. Contents of the invention [0003] The purpose of the present invention is to provide a kind of RDX base network explosive ink an...
