Problems solved by technology

[0002] At present, the oil phase materials used in the production of emulsion explosives by domestic high-temperature sensitization process emulsion explosives are mainly made of petroleum by-product paraffin products, which are compounded by adding emulsifiers, surfactants, etc., and the quality of oil phase materials is easily affected. Fluctuations in the quality of petroleum by-products are affected, thereby affecting the quality of emulsion explosives
At the same time, the price of petroleum by-products is high, and there is a waste of resources in the production of explosives

Embodiment Construction

[0015] A method for preparing an oil phase for high-temperature sensitized emulsion explosives by using coal-to-oil intermediate products, comprising mixing coal-to-oil intermediate products, wax materials, sp-80 emulsifiers, and polymer surfactants, the weight ratio of the four materials being 50-55:12-17:18-22:5-10, the four kinds of materials are added into the mixing tank by metering, heated and stirred for 40-70min, and the temperature is controlled at 75±5°C to form a composite oil phase, coal-to-oil The intermediate product is composed of linear hydrocarbons and oxygenated organic compounds, and is a semi-finished product in the process of coal-to-oil production.

[0016] The coal-to-liquid intermediate product is a coal chemical technology that uses coal as raw material to produce liquid fuel and chemical raw materials. The index of the coal-to-liquid intermediate product is 100°C kinematic viscosity of 10-14mm 2 / s, 20°C density 800-900kg / m 3 , freezing point 0-15°C, ...

Abstract

An oil phase for an emulsified explosive prepared by using a coal-to-oil intermediate product in a high-temperature sensitization process is composed of a coal-to-oil intermediate product, a wax material, an sp-80 emulsifier, and a polymer surfactant, and the weight ratio of the four materials is 50 ‑55: 12‑17: 18‑22: 5‑10, the four materials are metered into the mixing tank, heated, stirred and mixed for 40‑70min, and the temperature is controlled at 75±5°C to form a composite oil phase; The coal-to-liquid intermediate product is a semi-finished product in the process of coal-to-liquid production, that is, the coal-to-liquid intermediate product. The invention has the advantages that no other oil-phase materials need to be added, the performance indexes of the produced emulsion explosive can fully meet the national standards, and the product has the advantages of good fluidity, low pumping pressure 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 an emulsified explosive in a high-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 high-temperature sensitization process emulsion explosives are mainly made of petroleum by-product paraffin products, which are compounded by adding emulsifiers, surfactants, etc., and 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 intermediate products are used...
