Abstract

The invention relates to the field of industrial technologies, in particular to a preparation method of an on-site mixed-loading emulsion matrix. The on-site mixed-loading emulsion matrix is prepared from, by mass, 15-19 parts of water, 50-78 parts of ammonium nitrate, 1.2-2 parts of 30# engine oil, 3-3.5 parts of diesel oil, 2 parts of emulsifier and 0.15-0.2 part of phosphoric acid. According to the preparation method, the shelf life (two months) of the emulsion matrix can be effectively prolonged, load distance can reach 500 kilometers at normal temperature, and the requirements for trans-regional and cross-border remote grading delivery and mine explosion pre-installing can be met.

Description

technical field [0001] The invention relates to the field of industrial technology, in particular to a method for preparing an on-site mixed emulsified base. Background technique [0002] In today's society with the development of civilization, industrial explosives have developed from a kind of craftsmanship to a modern science and technology, reducing the danger in the preparation and use of explosives, and new techniques and technologies for the preparation of explosives that are safe, environmentally friendly and energy-saving.
