Problems solved by technology

During the use of lubricating oil, except for a small part that is consumed due to volatilization, leakage, oxidation and other reasons, most of it remains in the mechanical equipment. However, during the use process, the entry of external pollutants and the self-oxidation of the oil, Both will lead to a decrease in the performance of the oil and cannot continue to be used
The recycling of waste lubricating oil has become the focus of attention. Improper disposal of waste engine oil not only wastes resources, but also causes harm to the environment.

Abstract

The invention particularly relates to a method for preparing a heavy ammonium nitrate-fuel oil explosive by utilizing waste engine oil. The method comprises the following steps of carrying out pretreatment to obtain regenerated engine oil, preparing a latex matrix, preparing an ammonium nitrate-fuel oil explosive, preparing an emulsion explosive and preparing the heavy ammonium nitrate-fuel oil explosive. The method for preparing the heavy ammonium nitrate-fuel oil explosive by utilizing the waste engine oil has the following advantages that after the waste engine oil is used for preparing the heavy ammonium nitrate-fuel oil explosive, on one hand, the problems of emission and pollution of the waste engine oil on a job site are solved, on the other hand, the purchase cost of raw materials of explosive production is reduced, environmental benefits and economic benefits are good, safety is high, cost is low, the recovery range is wide, and the method is beneficial for protecting environment.

Description

technical field [0001] The invention belongs to the technical field of chemical industry and relates to a method for preparing explosives, in particular to a method for preparing heavy ammonium oil explosives by using waste engine oil. Background technique [0002] Heavy ammonium oil explosive is a new type of industrial explosive blended with emulsion explosive and ammonium oil explosive in a certain proportion. It is characterized by good water resistance, high workability and adjustable density. It is especially suitable for metallurgy, building materials, coal It is often used in medium and deep hole blasting in open-pit mining operations. It is widely used in blasting projects with large blast hole diameters, a lot of water, pre-charged charges, and a large amount of blasting at a time. The oil phase material of heavy ammonium fuel explosive requires a large amount of diesel and engine oil. With the rise of oil prices in recent years, the production cost of heavy ammoni...
