Embodiment Construction

[0023] In a specific embodiment of the present invention, in parts by weight, the basic components of the composite emulsifier used for emulsion explosives are: oil-soluble surfactant OSP: 30-70 parts, calcium sulfonate 5-30 parts parts, sorbitan monooleate: 5-30 parts, soybean lecithin 5-30 parts, oleic acid 5-15 parts. Wherein, the oil-soluble surfactant OSP adopted is the OSP series produced by U.S. Dow Chemical Company; One or a mixture of several kinds; the oleic acid used is a mixture of one or two kinds of vegetable oleic acid or animal oleic acid; the sorbitol monooleate used is a product of the Span Series, especially Span-80.

[0024] Oil-soluble surfactant (OSP-68), calcium sulfonate, sorbitan monooleate (Span-80), soybean lecithin and oleic acid are mixed according to the parts by weight shown in Table 1, The composite emulsifier for emulsion explosives of the present invention can be prepared. The mixing order of each component has no obvious effect on the perf...

Abstract

The invention discloses a compound emulsifier for an emulsion explosive. The compound emulsifier comprises the following components as follows in parts by weight: 5-70 parts of oil-soluble surfactant OSP, 1-30 parts of calcium sulfonate, 3-60 parts of sorbitol monooleate and 3-15 parts of oleic acid. The compound emulsifier disclosed by the invention is applicable to the preparation of the emulsion explosive of level 1 emulsion process; consequently, the prepared emulsion explosive is stable in storage and excellent in explosion performance.

Description

technical field [0001] The invention relates to a composite emulsifier for emulsion explosives Background technique [0002] Emulsion explosives have good waterproof and explosive properties, high degree of production automation, and good safety. They are currently being vigorously developed for civilian use. At present, the continuous production process of emulsion explosives includes two-stage emulsification process and single-stage emulsification process. The single-stage emulsification process is the main process for the production of emulsion explosives in my country because of its better safety. Compared with the two-stage emulsification process, the emulsification time and emulsification strength of the single-stage emulsification process are greatly reduced. [0003] Chinese patent application 96121659.X discloses an emulsifier for an emulsion explosive composition containing a first lipophilic group, a second lipophilic group and a hydrophilic group, and these grou...
