[0002] At present, the composite oil phase materials used by domestic on-site mixed emulsion explosive production units to produce on-site mixed emulsion explosives are mainly composed of petroleum by-products (such as diesel oil, engine oil, etc.), and are compounded with a small amount of additives. The composite oil phase products The quality is easily affected by fluctuations in the quality of petroleum by-products, thus affecting the quality of mixed emulsified explosives on site
At the same time, the price of petroleum by-products is high, and there is a waste of resources in the production of explosives

Abstract
An oil phase for preparing on-site mixed emulsified explosives from coal-to-oil intermediates includes coal-to-oil intermediates, sp-80 emulsifier, and polymer surfactant, and the weight ratio of the three is 70-80:9-6: Between 21 and 14, the three are metered into the mixing tank, heated and stirred for 40-70min1, the temperature is controlled at 60±5°C, and mixed to form a composite oil phase; the coal-to-oil intermediate product is the coal-to-oil production process A semi-finished product, that is, an intermediate product of coal-to-oil. The invention has the advantages that no other oil phase materials need to be added, and the various performance indexes of the produced emulsion explosive can fully meet the national standards, and the product has the advantages of good fluidity, easy sensitization and the like. The composite oil phase has high calorific value, good safety performance, convenient use, low price, wide sources of various raw materials, and high economic benefits.
Description
technical field [0001] The invention relates to a formula of an oil phase, in particular to an oil phase for preparing on-site mixing emulsified explosives by using a coal-to-oil intermediate product and a preparation method thereof. Background technique [0002] At present, the composite oil phase materials used by domestic on-site mixed emulsion explosive production units to produce on-site mixed emulsion explosives are mainly composed of petroleum by-products (such as diesel oil, engine oil, etc.), and are compounded with a small amount of additives. The composite oil phase products The quality is easily affected by fluctuations in the quality of petroleum by-products, thus affecting the quality of mixed emulsion explosives on site. At the same time, the price of petroleum by-products is relatively high, and there is a waste of resources in the production of explosives. In order to reduce costs and save resources, low-cost coal-to-oil intermediates are used instead of pe...
