Description

technical field [0001] The invention relates to the technical field of industrial explosive production, in particular to an emulsifier for remote distribution of latex matrix and its preparation method and application. Background technique [0002] As a key component of emulsion explosives, emulsifiers have a significant impact on the quality of the emulsified system, the size of internal phase ions, stability and detonation performance. [0003] The low-molecular-weight emulsifier represented by Span-80 has high emulsification efficiency and low cost, which can satisfy the production of conventional emulsion explosives. However, the emulsion particles form micelles, and the interface forms a film that is not tightly packed. Because the formed film is very thin (thickness about ), there is no elastic frame structure, so the interface film has insufficient elasticity, is easy to age, crack, has poor stability, and has a short shelf life. [0004] In the emulsification syst...
