Abstract
The invention relates to an emulsifier, in particular to an environment-friendly emulsion explosive compound emulsifying agent, aiming at solving the problems of being single in the type of the emulsifying agent used in the production of emulsion explosive and not being capable of meeting the market demand in the prior art. The emulsifying agent consists of the raw materials with the following parts by weight: 30-40 parts of bis-polyisobutylene-succinimide (T152), 50-65 parts of sorbitan monooleate (S-80), and 3-6 parts of sorbitan polyethenoxy ether glycerintrioleate (T-85). When in emulsification, stronger frame structure can be formed, so as to lead the molecular arrangement to be more compact, and increase the intensity of an interfacial film and the coating effect on water phase, thus not only realizing easy emulsification, but also ensuring the storage stability of the explosive. The explosion performance of the emulsion explosive can be effectively improved.
Description
Technical field
The present invention relates to a kind of emulsifying agent, be specially a kind of environment protective emulsive explosive composite emulsifying agent.
Background technology
Emulsifying agent is a kind of raw material of key in the production of emulsion explosive, and under the certain condition of prescription and other raw material and technology, it is determining the blast performance of emulsion explosive and the stability of storage.The emulsifying agent that at present domestic main use S-80 or double focusing iso-butylene succimide use as emulsion explosive production.It is low that S-80 has the requirement emulsion strength, easily emulsification, the advantage of explosive production easy to implement, but product instability storage period of producing, S-80 with oil phase material, water-phase material in the impurity effect time molecule in two easy oxidation scissions of key, the water that is wrapped up by oil phase will enter oil phase, causes the emulsifying base breakdown of emulsion, emulsion explosive was lost efficacy, and blast effectiveness is also not fully up to expectations.With two succimides is that the explosive of emulsifying agent production has the high advantage of package stability, but emulsification desired strength height is relatively harsher to manufacturing technique requirent.Flourish along with China's capital construction, emulsion explosive application increase sharply.S-80 or two succimide can not adapt to the needs of emulsion explosive development fully.In this year, the scientific research personnel is also arranged with the compound use of two or more emulsifying agent.Huainan Polytechnique College's journal 1998, people such as 18 (4) 29-31 Xing Hong dragons have carried out the research of emulsion explosive emulsifying agent consistency, the result shows that the consistency of polyisobutene succinimide emulsifying agent and Valelinum Liquidum is good, linearly the molecular chain state is dissolved in the oil, increase with the dispersity at oil phase behind the SPAN-80 formation compound emulsifying agent, emulsion explosive system stability is strengthened.Colliery blasting.2003 (2) disclose the application of STL type compound emulsifying agent in emulsion explosive, have introduced the characteristics of S-80 or two succimide class emulsifying agents in the document, and have carried out the application test of compound emulsifying agent, have determined the rational proportion of STL type compound emulsifying agent.Experiment shows, adopts compound emulsifying agent can overcome the deficiency of single emulsifying agent, and the package stability of raising explosive reduces production costs.But can't satisfy the weakness of improving Emulsion Explosive Stability difference and emulsification condition requirement harshness.With SPAN-80, two succimide, tween is ternary compound emulsifying agent existing application in lubricating oil additive and diesel oil emulsifier of raw material, but does not see its open report with application in emulsion explosive as yet.
Summary of the invention
The present invention is single in order to solve the emulsifying agent kind of using in the emulsion explosive production that exists in the prior art, the problem that can not meet the need of market and a kind of environment protective emulsive explosive composite emulsifying agent is provided.
The present invention is realized by following technical scheme, a kind of environment protective emulsive explosive composite emulsifying agent, form by following materials of weight proportions, double focusing iso-butylene succimide (T152) 30-40 part, sorbitan monooleate (S-80) 50-65 part, anhydrous sorbitol Soxylat A 25-7 trioleate (T-85) 3-6 part
Sorbitan monooleate (S-80), anhydrous sorbitol Soxylat A 25-7 trioleate (T-85) with above-mentioned part by weight, under 100-110 ℃ condition, mix, and then the two mixed solution and double focusing iso-butylene succimide (T152) mixed under 100-110 ℃ condition.
The emulsifying agent of the emulsion explosive that we use at present is based on sorbitan monooleate (S-80), double focusing iso-butylene succimide (T-152), and tween series is auxilliary.We at first use tween series anhydrous sorbitol Soxylat A 25-7 mono-laurate (T-20), anhydrous sorbitol Soxylat A 25-7 monopalmitate (T-40), anhydrous sorbitol Soxylat A 25-7 monostearate (T-60), anhydrous sorbitol Soxylat A 25-7 trioleate (T-85) etc.Ratio with sorbitan monooleate (S-80), double focusing iso-butylene succimide (T152), tween series 6:3:1-3 is made compound emulsifying agent, and its effect is as follows:
From experimental result, S-80+T152+T-85 group (being called for short the STT group) consistency is better, and emulsifying effectiveness is better.
The selection of proportion scale: at first investigate the compatibility situation of S-80+T152, its effect such as following table:
Can see that from above-mentioned experiment S-80 and T152 ratio are that 3:2 or 2:3 effect are relatively good, but consider that 3:2 is first-selected from the cost angle.
According to S-80 and T152 ratio is that the T-85 combined experiments effect of the proportion relation of 3:2 and different ratios is as follows:
| Numbering | S-80+T152 | T-85 | Become the cream time (part) | The emulsifying base situation |
| STT1 | 80 | 20 | 3.5 | Easily emulsification, matrix is rarer |
| STT2 | 85 | 15 | 4 | Easily emulsification, matrix is than thickness |
| STT3 | 90 | 10 | 4.5 | Easily emulsification, the matrix thickness |
| STT4 | 95 | 5 | 5 | Easily emulsification, the matrix thickness |
For the actual effect of the compound emulsifying agent of testing different ratios, following rock explosive blast performance contrast table for using the different ratios emulsifying agent to produce
| Group | Gap distance (cm) | Average brisance (mm) | Average explosion velocity (m/s) |
