Composite oil phase for explosive latex matrix and on-site mixed explosives, preparation method

Abstract

The invention provides a composite oil phase for explosive latex matrix, on-site mixed explosives and a preparation method. The compound oil phase includes 62-84% of paraffin-based neutral oil and 16-38% of emulsifier, which is easy to emulsify, has good emulsifying effect and stable quality. The present invention also provides a latex matrix formed by the compound oil phase and the water phase using a single salt phase formula. The latex matrix has good stability and strong anti-turbulence performance, and can meet the requirements of remote distribution, repeated pumping, Mine blasting pre-charge requirements; easy to disperse, suitable for redispersion and mixing of static mixers, and improve the sensitization effect. The invention also provides an on-site mixed explosive, the explosive has excellent explosive performance and low charge pressure, which greatly improves the safety of the charge process.

Description

technical field

[0001] The invention belongs to the technical field of emulsion explosive manufacture, and in particular relates to a compound oil phase for explosive latex matrix, on-site mixed explosive and a preparation method. Background technique

[0002] On-site mixing technology began to be studied in the late 1980s, and was successfully applied in Benxi Iron and Steel Nanfen Iron Mine in 1990, but it has been developing slowly. The current on-site mixed emulsion explosive production technology has the following problems:

[0003] (1) On-site mixed emulsified explosive formula At present, most domestic emulsified explosive formulas have been applied mechanically, and the water content is relatively low, generally around 10%. The cost is high, the viscosity of the produced latex matrix is ​​relatively high, and the pumping pressure of the on-site mixing truck is relatively high, usually up to 1.2MPa, and there are certain potential safety hazards.

[0004] (2) Some e...
