Abstract
The invention provides an emulsifier used for pre-charge. The emulsifier is prepared from 80-85wt% of a Span-80 emulsifier, 10-16wt% of a polyisobutylene succinimide polymer emulsifier, and 0.5-0.8% of granulesten. The emulsifier used for pre-charge has the advantages of 2-3 months or more of the stable time of a colloid, 2-3 times improvement of the stable storage period, and very substantial technological economic benefit.
Description
Technical field
The present invention relates to a kind of emulsifying agent that is applied to pre-powder charge, belong to chemical field.
Background technology
At home and abroad in the R﹠D and production of emulsion explosive, be widely used dehydrating sorbitol monooleate (commodity are called for short Span-80) and make emulsifying agent, but relatively poor some shortcomings such as grade of the emulsoid stability in storage of Span-80 have been impelled people to study and have been sought new efficient emulsifying agent.The exploitative experiment of the structure by Surfactant and emulsifying effectiveness, stable Relations Among, and to the shaker test of different varieties emulsifying agent, established the possibility that polyisobutene succinimide macromolecule emulsifier (being called for short the PCE emulsifying agent) is used in emulsion explosive.Yet since polyisobutene succinimide macromolecule emulsifier price more expensive, therefore expensive 2～3 times than Span-8O emulsifying agent, be difficult to be accepted by enterprise as emulsifying agent separately.Simultaneously, because viscosity is larger, it is difficult to use in emulsified explosive car commonly used.Under the day by day strong situation of the needs of the pre-powder charge technology to emulsion explosive, it is just imperative to explore a kind of new compound emulsifying agent.
Summary of the invention
The object of the present invention is to provide a kind of emulsifying agent that is applied to pre-powder charge.
Technical scheme of the present invention is:
A kind of emulsifying agent that is applied to pre-powder charge by following raw materials according is by weight percentage: the Span-8O emulsifying agent: 80%～85%, and the polyisobutene succinimide macromolecule emulsifier: 10%～16%, soybean phospholipid: 0.5%～0.8% is formulated.Its preparation method is as follows: take Span-8O emulsifying agent, polyisobutene succinimide macromolecule emulsifier and soybean phospholipid as raw material, at first place the drying room preheating more than 5 hours the polyisobutene succinimide macromolecule emulsifier; Then the Span-8O emulsifying agent is put into 5M
3Reactor in heat up and to be heated to 150 ℃, uniform stirring 20 minutes; Then the polyisobutene succinimide macromolecule emulsifier is drawn into 5M by vacuum
3Reactor in, add simultaneously soybean phospholipid, the three is after stirring 60 minutes under 150 ℃ of conditions, sampling detects, qualified after, carry out the discharging packing.
The invention has the beneficial effects as follows: the colloid-stabilised time is 2～3 months, even can reach the longer time, and the stably stored phase is improved 2～3 times, and its technical economic benefit is also very remarkable.
Embodiment
A kind of emulsifying agent that is applied to pre-powder charge, its preparation methods steps is: take Span-8O emulsifying agent, polyisobutene succinimide macromolecule emulsifier and soybean phospholipid as raw material, at first place the drying room preheating more than 5 hours 0.5 ton of polyisobutene succinimide macromolecule emulsifier; Then 3 tons of Span-8O emulsifying agents are put into 5M
3Reactor in heat up and to be heated to 150 ℃, uniform stirring 20 minutes; Then 0.5 ton of polyisobutene succinimide macromolecule emulsifier is drawn into 5M by vacuum
3Reactor in, add simultaneously 100 kilograms of soybean phospholipids, the three is after stirring 60 minutes under 150 ℃ of conditions, sampling detects, qualified after, carry out the discharging packing.
