Oil phase for medium-low temperature sensitization process emulsion explosive and prepared from coal-to-oil intermediate product and preparation method thereof

Abstract

The invention disclosesan oil phase for a medium-low temperature sensitization process emulsion explosive and prepared from a coal-to-oil intermediate product. Theoil phase comprises the coal-to-oil intermediate product, a wax material, an SP-80 emulsifier and a polymer surfactant according to a weight ratio of (45-55): (15-20): (25-30): (5-10); and the four materials are metered and added into a mixing tank to be heated, stirred and mixed for 40-70 min, the temperature is controlled to be 75 + / -5 DEG C, and the materials are mixed to form the composite oil phase, wherein the coal-to-oil intermediate product is a semi-finished product in the coal-to-oil production process, namely the coal-to-oil intermediate product. The oil phase has the advantages that no other oil phase material is added, various performance indexes of the produced emulsion explosive can completely reach the national standard, and the product has the advantages of good fluidity, low pumping pressure and the like. The composite oil phase has the advantages of higher calorific value, favorable safety performance, convenience in use, low price, wide sources of various raw materials and higher economic benefit.

Description

technical field [0001] The invention relates to an oil phase formula, in particular to an oil phase for preparing an emulsion explosive in a medium-low temperature sensitization process by using a coal-to-oil intermediate product and a preparation method thereof. Background technique [0002] At present, the oil phase materials used in the production of emulsion explosives by domestic medium and low temperature sensitization process emulsion explosives are mainly made of petroleum by-product paraffin products, which are compounded by adding emulsifiers, surfactants, etc. The quality of oil phase materials is easily affected. The fluctuation of the quality of petroleum by-products is affected, thereby affecting the quality of emulsion explosives. 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 ins...
