Problems solved by technology

[0003] The technical problem to be solved by the present invention is how to solve the technical problems of the size and uneven distribution of the sensitized bubbles in the emulsion explosive, insufficient foam stabilizing ability, pressure desensitization, short storage period of the explosive and too fast performance degradation of the explosive after being pressurized, Aiming at the shortcomings of the above existing technologies, a pressure-resistant colloidal explosive for underwater blasting and its preparation process are proposed. The preparation process is simple and easy, and the prepared explosive is resistant to extrusion, and the bubbles are not easy to gather after being pressurized. and overflow, strong foam-fixing ability, long storage period, stable quality

Abstract

The invention discloses an extrusion-resistant colloidal explosive for underwater explosion. The extrusion-resistant colloidal explosive comprises the following components: microcrystalline wax, a methylamine nitrate solution, methylamine nitrate, ammonium nitrate, sodium nitrate, perlite, a foaming agent, a foaming accelerant, sesbania powder, a stabilizer, a cross-linking agent, a surfactant, water, an oxidant, a sensitizer, an emulsification foaming adhesive and an emulsifier. The invention further designs a preparation process of the extrusion-resistant colloidal explosive for underwater explosion. The preparation process is simple and feasible, and the prepared explosive is high in extrusion resistance, high in bubble immobilization capability, long in preservation life and stable inquality, and bubbles are not liable to aggregate or overflow after being extruded.

Description

technical field [0001] The invention relates to an explosive, in particular to a pressure-resistant colloidal explosive for underwater blasting and a preparation process thereof. Background technique [0002] In modern marine development, blasting in deep water is widely used. For example, it is often necessary to destroy underwater oil pipelines, water pipelines, underwater optical cables, cables, and underwater hydraulic structures. When clearing waterways, it is necessary to destroy shipwrecks and abandoned oil wells. Blasting and cleaning of pile legs of well pipes and water operation platforms; blasting of reefs and deep-water cofferdams in deep-water pipe trench excavation, deep-water port construction and deep-water bridge pile foundation pit excavation in marine development; oil well and water well drilling When the drill is stuck, it is necessary to blast the drill pipe. These blasts are usually carried out in water tens of meters deep. The water gel explosive is in...
