Embodiment 1

[0050] The following raw materials were weighed in parts by mass: No. 5 white oil: 36 parts, KN4010: 30 parts, polymer ester emulsifier: 30 parts, polyisobutylene: 2 parts, stearic acid: 2 parts. Prepared in the following manner:

[0051] First, heat No. 5 white oil, KN4010, and high-molecular ester emulsifier in a separate melting tank to 60-70°C, then pump them into the reaction kettle sequentially through the oil pump and electronic scale according to the proportioning requirements, stir, After heating up to 80°C, add the measured polyisobutene and stearic acid, and continue to stir for about 30 minutes. After the polyisobutene and stearic acid are fully melted, the finished product is obtained after filtration.

Embodiment 2

[0053] No. 10 white oil: 38 parts, KN4006: 27 parts, polymer ester emulsifier: 28 parts, S-80: 2.5 parts, polyisobutylene: 2.5 parts, palmitic acid: 2 parts. Prepared in the following manner:

[0054] First, heat No. 10 white oil, KN4006, polymer ester emulsifier, and S-80 in a separate melting tank to 60-70°C, and then pump them into the reaction kettle sequentially through the oil pump and electronic scale according to the ratio requirements Inside, after stirring and raising the temperature to 85°C, add the measured polyisobutene and palmitic acid, and continue to stir for about 30 minutes. After the polyisobutene and palmitic acid are fully melted, the finished product is obtained after filtration.

Embodiment 3

[0056] No. 15 white oil: 37.5 parts, KN4006: 20 parts, KN4010: 10 parts, polymer ester emulsifier: 28 parts, polyisobutylene: 2.5 parts, stearamide: 2 parts. Prepared in the following manner:

[0057] First, heat No. 15 white oil, KN4006, KN4010, and high molecular weight ester emulsifier in a separate melting tank to 60-70°C, then pump them into the reaction kettle sequentially through the oil pump and electronic scale according to the ratio requirements. After stirring and raising the temperature to 90°C, add the measured polyisobutene and stearamide, and continue stirring for about 30 minutes. After the polyisobutene and stearamide are fully melted, the finished product is obtained after filtration.

Abstract

The invention discloses a composite oil phase for preparing bulk emulsified explosives with upward hole charges. The composite oil phase consists of white oil, naphthenic oil, polymer ester emulsifier, crosslinking agent, S-80 , anti-turbulence agent, and prepared by the following method: first heat white oil, naphthenic oil, polymer ester emulsifier, and S-80 in separate melting tanks to 60-70°C, and then mix according to the ratio requirements The oil pump is measured by the electronic scale and then pumped into the reaction kettle one by one. After stirring and heating up to 80-90°C, add the measured cross-linking agent and anti-turbulence agent, and continue stirring for about 30 minutes until the cross-linking agent and anti-turbulence agent are fully After melting, the finished product is obtained after filtering. The bulk emulsion explosive produced by the composite oil phase of the present invention has the remarkable characteristics of good explosive performance, high working capacity, long storage period, anti-turbulence, long-distance transportation, small colloidal viscosity gradient coefficient, and easy pumping at room temperature. When used in underground mines to charge holes, the rate of drug return is extremely low. It can replace imported products to produce high-quality bulk emulsion explosives, and has good economic benefits.

Description

technical field [0001] The invention relates to the field of industrial explosives, in particular to a composite oil phase for preparing bulk emulsified explosives for upward hole charging. Background technique [0002] In the field of civil blasting, bulk emulsion explosives are a kind of oil-water phase solution or latex matrix that is prepared centrally by fixed or mobile ground stations, and the oil-water phase solution or latex matrix is ​​carried by the charging vehicle to the charging site to complete the latex matrix preparation (vehicle oil-water phase solution time), sensitization, and filling technology have been widely used because of their wide range of use, simple, quick, and safe steps. Since the mid-1990s, Western countries have developed a ground-based centralized preparation of latex matrix dispersed charge system, that is, the "latex matrix remote delivery" system. The so-called "remote distribution of latex matrix" system, like ordinary ammonium nitrate,...
