Problems solved by technology

[0004] (1) Viscous explosives that do not contain TNT. The formula of viscous explosives is porous ammonium nitrate, diesel oil, and adhesive explosives. Since the substances in the formula cannot meet the performance requirements of explosives, in order to improve the explosive performance and sensitivity of explosives, viscous Adding methylamine nitrate to the mixture improves its performance, but methylamine nitrate is a simple explosive, adding this increases the safety risk of explosives
In some explosive formulations, no other substances are added to the binder, but in order to improve the performance of the explosive, a certain amount of aluminum powder must be added to the explosive, but the aluminum powder is very dusty and harmful to the human body after inhalation. Sometimes the workers' hands are not easy to clean, and there are many residues, which are harmful to health
[0005] (2) In the viscous explosives containing TNT, since the explosive itself contains TNT and other components, it is not necessary to add a simple explosive to the adhesive to improve the explosive performance, but TNT itself is highly dangerous and has a high safety risk

Abstract

The invention discloses an adhesive for viscous explosives. The adhesive is prepared from, by weight, 20-45% of ammonium nitrate, 0.1-4% of a flocculant, 3-15% of an alcohol-type polymer and 40-80% of water. The invention further provides a preparation method of the adhesive for the viscous explosives. The adhesive prepared with the method has certain fluidity and adhesiveness, more convenience is achieved in production and use of the viscous explosives, adhesiveness and explosive performance of the viscous explosives are improved, and safety of the explosives is improved.

Description

Technical field [0001] The invention relates to an adhesive, in particular to an adhesive for viscous explosives and a preparation method thereof. Background technique [0002] The viscous granular explosive is a new type of explosive suitable for underground medium-deep hole mechanical charging. It basically does not return when charging and has less dropout, which effectively improves the harm of dust to the health of workers. [0003] At present, the preparation of adhesives for viscous explosives mainly includes the following methods: [0004] (1) TNT-free viscous explosives. The formulations of the viscous explosives are porous ammonium nitrate, diesel fuel, and adhesive explosives. Since the substances in the formulation cannot meet the performance requirements of the explosive, in order to improve the explosive performance and sensitivity of the explosive, Methylamine nitrate is added to the mixture to improve its performance, but methylamine nitrate is a simple explosive, ad...
