Abstract

A liquid composite oil phase used for an emulsion explosive is disclosed. The liquid composite oil phase comprises 20-50 parts by weight of composite wax, 5-25 parts by weight of microcrystalline wax, 5-20 parts by weight of base oil, 10-30 parts by weight of an oleic acid derivative emulsifier, 5-20 parts by weight of a polyisobutene butanedioic anhydride derivative emulsifier and 0-5 parts by weight of a modifier. A preparing method of the liquid composite oil phase includes adding the composite wax, the microcrystalline wax and the modifier according the ratio, fully melting at 80-100 DEG C, adding the base oil, the oleic acid derivative emulsifier and the polyisobutene butanedioic anhydride derivative emulsifier, fully stirring, filtering, conveying to a thermal-insulating storage tank and storing, and when the liquid composite oil phase is to be used, the liquid composite oil phase is directly conveyed through an oil tank truck to a thermal-insulating tank of an emulsion explosive production line. The liquid composite oil phase is adjustable in hardness of an explosive base, and can avoid explosive deterioration caused by amidation and other side reactions in long-time high-temperature storage processes. The method has beneficial effects of energy conservation, emission reduction and high production safety.

Description

technical field [0001] The invention relates to a liquid composite oil phase for explosives and a preparation method thereof, in particular to a liquid composite oil phase for emulsion explosives and a preparation method thereof. Background technique [0002] Compared with other industrial explosives, emulsion explosives are widely used because of their good water resistance, safety performance and bombing performance, as well as the advantages of wide source of raw materials, high production efficiency and high degree of automatic production. [0003] CN 103497074A discloses a liquid composite oil phase, the oil components of which are HV1 base oil and chlorinated paraffin, which are quite different from the currently used microcrystalline wax, paraffin wax, mechanical oil, composite wax, etc., and are different from those of emulsion explosives. The emulsification and sensitization processes are not matched, and cannot fully meet the technical requirements of the explosive...
