Abstract
The invention relates to a surfactant, and especially relates to a composite emulsifier with the characteristics of uniform quality, long preservation period, no environmental pollution, good emulsification capability and stable use in emulsion explosive. The composite emulsifier solves the problems of inhomogeneous quality, unstabilization, short preservation period, large fluctuation in the application in emulsion explosive. The composite emulsifier comprises the following raw materials by weight percentage: 30-40% of food additive modified soybean lecithin, 60-70% of high viscosity emulsifier (Span-80) and 0-5% of polyolefin derivative (LR-1). The composite emulsifier used in the production of the emulsion explosive is capable of raising the quality and stability of the emulsion explosive and effectively raising the preservation period of the emulsion explosive.
Description
Technical field
The present invention relates to tensio-active agent, particularly a mass homogeneous, storage period are long, and non-environmental-pollution, emulsifying capacity are good, emulsion [explosive is used the stable composite emulsifying agent.
Background technology
In the emulsion explosive prodn, emulsifying agent is a very The key factor, and under the identical situation of other condition, it is determining the quality and the package stability of emulsion [explosive product.At present, widely used in the preparation of emulsifying explosive is Span-80 and polyisobutene amides emulsifying agent.It is low that Span-80 has emulsion strength, is prone to the emulsive advantage, but the emulsion explosive prodn processing condition are had certain requirement, and the product of production just can have stable storage period.Polyisobutene amides emulsifying agent is applied in the emulsion explosive prodn because of its good stability in storage, but emulsion strength is high, and is relatively harsher to manufacturing technique requirent.In recent years; Along with improving constantly of China's serialization robotization emulsion explosive production line technology; Emulsifying agent is also had higher requirement; Span-80 or polyisobutene amides emulsifying agent can not adapt to the needs of emulsion [explosive development fully, and compound emulsifying agent more is applicable to the emulsion explosive prodn technology that present full continuous automatic is heat-sensitized than single emulsifying agent.In recent years, also have compound emulsifying agent in emulsion [explosive, to use on the market, but this compound emulsifying agent itself is inhomogeneous, package stability is very poor, less than just layering fully in four months, in emulsion [explosive, uses unstable.In view of the foregoing, invent a kind of good stability, the quality homogeneous is grown (12 months not stratified), emulsify well storage period, and the compound emulsifying agent of non-environmental-pollution improves emulsion [explosive quality and package stability to adapt to modern emulsion explosive prodn processing requirement.
Summary of the invention
The object of the invention is exactly a kind of compound emulsifying agent that provides for the defective that overcomes above-mentioned prior art existence.
The object of the invention can be realized through following technical scheme:
A kind of emulsion [explosive is used compound emulsifying agent; Form for raw material by foodstuff additive modified soy bean lipoid, HV emulsifying agent Span-80, polyolefin derivative thing (LR-1); Each component by weight percentage ratio in reactor drum; After fully speed change stirred, composite forming: each components contents scope was under high vacuum condition:
Phosphatidase 13 0-40%
Span-80 60-70％
LR-1 0-5％
Emulsion [explosive of the present invention is compared with existing emulsifying agent with compound emulsifying agent, has raw material and is prone to purchase, and compound energy consumption is low, and technology is simple, and is nontoxic, pollution-free, no coupling product, and quality is uniform and stable, and storage period is long, and emulsifying power is strong; Be applied in the emulsion explosive prodn and can reduce the emulsion explosive prodn cost, effectively improve emulsion [explosive performance and package stability.
