Abstract

The invention discloses an MY type colloid emulsified civil explosive which comprises the following raw materials in percentage by weight: 35%-45% of ammonium nitrate, 6.5%-7.5% of sodium nitrate, 6%-10% of potassium nitrate, 15%-16% of flame inhibitors, 1.5% of urea, 3.5%-4% of emulsifying agents, 10% of water, 6%-6.3% of oil phases, 1.6%-1.8% of foaming agents, 0.15% of foaming promoters, 4.2%-4.4% of expanded perlite, 0.5% of mixed rare earth and 2.5%-6.5% of titanium hydride. The preparation process of the emulsified explosive comprises the steps of water phase preparation, oil phase preparation, emulsification, sensitization and charging. The MY type colloid emulsified civil explosive disclosed by the invention ensures the safety of the emulsified explosive, enhances the explosiveness and detonation sensitivity of the emulsified explosive and has high storage stability.

Description

technical field [0001] The invention belongs to the technical field of explosive preparation, and relates to a MY type colloidal emulsified civil explosive and a production process thereof. Background technique [0002] Permissible explosives in coal mines are an important part of industrial explosives in my country. They are classified according to the conditions of use of industrial explosives and are specially designed for use in underground coal mines where there is a risk of combustible gas and coal dust explosions. [0003] At present, the commonly used explosives are emulsion explosives. The raw materials of emulsion explosives come from a wide range of sources, are low in cost, do not contain TNT which is harmful to the human body, and conform to the planning direction of the national civil explosive product industry development. At the same time, this variety of explosives also has good explosive performance, The advantages of strong water performance, reliable deton...
