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

The invention discloses an oil phase prepared from a coal-to-oil intermediate product for high-temperature sensitization process emulsion explosive and a preparation method of the oil phase. The oil phase is composed of the coal-to-oil intermediate product, a wax material, an SP-80 emulsifier and a polymer surfactant according to a weight ratio of (50-55):(12-17):(18-22):(5-10). 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 mixing is carried out to form the compound oil phase; and the coal-to-oil intermediate product is a semi-finished product in the coal-to-oil production process, namely a coal-to-oil intermediate product. The invention 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 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...
