Problems solved by technology

However, the commonly used composite oil phase of the emulsion explosive with diesel oil and emulsifier has a low viscosity, but the storage period is short, and it often breaks and crystallizes within 7 to 10 days, which cannot meet the production needs of the vehicle-made emulsion explosive.

Embodiment Construction

[0007] The composite oil phase of the vehicle-made emulsified explosive of the present invention uses the following basic components in parts by weight: 855-50 parts of Span, 10-30 parts of alkenyl succinimide dispersant, liquid paraffin 6-60 parts, 2-20 parts of extracted oil, 6-30 parts of vegetable oil. Wherein, the alkenyl succinimide dispersant is one or more mixtures of monoalkenyl succinimide, dienyl succinimide, and high molecular weight succinimide; The liquid paraffin is one or a mixture of heavy liquid paraffin or light liquid paraffin; the vegetable oil is one or more of castor oil, coconut oil, cottonseed oil, soybean oil; The extracted oil is a by-product in the lubricating oil processing process, and is an undesired component in the oil product separated when the lubricating oil material is extracted with a solvent in a lubricating oil solvent (furfural, phenol, NMP) refining device, and petroleum fractionation Extracted oil can also be obtained in the process,...

Abstract

The invention relates to a compound oil phase for emulsion explosives made by a loading machine, which is prepared from the following component in parts by weight: 5-50 parts of Span-85, 10-30 parts of alkenyl succinimide, 6-60 parts of liquid paraffin, 2-20 parts of extract oil and 6-30 parts of vegetable oil. The compound oil phase for emulsion explosives made by a loading machine has the advantages of low viscosity and stable state and properties, is easy for pumping and can be delivered at a long distance, and the storage period is longer than 180 days. In spite of low viscosity, the storage life of the existing compound oil phase, which mainly comprises diesel, is only 7-10 days, so that the existing compound oil phase can not be delivered at a long distance on a large scale.

Description

technical field [0001] The invention relates to a vehicle-loaded emulsified explosive, in particular to a composite oil phase of the charged vehicle-made emulsion explosive. Background technique [0002] Emulsion explosives are a new type of water-based ammonium nitrate explosives. It combines the advantages of ammonium oil explosives, slurry explosives and water gel explosives. It has good explosive performance, safe production and use, no pollution, and relatively With a series of advantages such as strong water resistance, it is an explosive variety that is mainly promoted in China's blasting industry. At present, there are more than 70 production lines of emulsion explosives that have been put into operation or are under construction in China, with advanced production technology. Charge vehicle-made emulsion explosive is the advanced equipment and technology used in large-scale open-pit mines at home and abroad. It requires the emulsion explosive matrix to have low visc...
