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.
[0058] The water-resistant composite oil phase of the above three groups of embodiments is used as a raw material to prepare bulk emulsion explosives according to the formula of bulk emulsion explosives, according to ammonium nitrate: water: composite oil phase = 75.8: 18: 6.2...
