Special compound wax for emulsion explosives based on heavy deasphalting oil

Abstract

The invention discloses special compound wax for emulsion explosives based on heavy deasphalting oil. The special compound wax comprises the following components: heavy deasphalting oil, dewaxing sweat oil, Fischer-tropsch wax and cerate. The preparation method comprises the following steps: melting the heavy deasphalting oil, sequentially adding the residual components under the condition of 85 to 95 DEG C, uniformly mixing, cooling and forming the product. The heavy deasphalting oil and dewaxing sweat oil serve as main raw materials, and the condition that the raw materials are contested during production of microcrystalline wax and petroleum wax; wax-containing raw resources in oil refinery are directly and effectively utilized, and the condition that the production cost is improved due to secondary processing is avoided; the use amount of cerate is as small as possible, so that the cost of the compound wax is reduced to the lowest degree; and the Fischer-tropsch wax at relatively low price is introduced, so that the viscosity, hardness, oil content and the like of the product are adjusted, and the requirements on novel emulsion explosive production process and performance improvement are met.

Description

technical field [0001] The invention relates to a compound wax specially used for emulsion explosives, and belongs to the technical field of petrochemical products. Background technique [0002] Explosives have a wide range of uses in the national economy and are generally valued by people. Emulsion explosives are a kind of water-in-oil emulsion type water-resistant industrial explosives developed by emulsification technology in the late 1960s. It not only solves the sensitivity problem of nitroglycerin explosives, that is to say, under the premise of ensuring the performance of explosives, it effectively improves the safety, but also solves the problem of low detonation sensitivity of ammonium nitrate explosives. Therefore, emulsion explosives are explosives Industry trends. The oil phase material constitutes the continuous phase of the emulsion explosive. In the emulsion explosive system, due to the limitation of oxygen balance and blasting performance requirements, the...
