Problems solved by technology

[0012] It can be seen that natural waxes, vegetable waxes and bran waxes have been used in the formulation of emulsion explosive oil phase materials in small quantities as oil phase varieties at home and abroad, but biomass-based composite oil phase materials prepared entirely from biomass raw materials are used for emulsification. Explosives have not been reported at home and abroad

Abstract

A composite oil phase comprises the following raw materials in percentage by mass: 1-80% of hydrogenated stearin, 0-80% of palm stearin (a melting point is 44-62 DEG C), 0-60% of bran wax (the oil content is 0-35%), 0-40% of palm fat (a melting point is 45-55 DEG C), 0-15% of fatty acid methyl ester and 19-50% of a compound emulsifier. A preparation method for a biomass composite oil phase material comprises the following steps: weighing a biomass oil phase at a formula ratio, heating and melting the biomass oil phase, uniformly mixing the molten biomass oil phase in a stirring tank, filtering a mixture through a filter to remove impurities in the biomass oil phase, pumping the filtered oil phase into a blending kettle, adding the emulsifier, performing heat preservation blending, performing cooling solidification in a cooling tank after blending, performing weighing and packaging, and the like. The biomass composite oil phase material is used for producing emulsion explosives, has good explosion performance, is clean and environment-friendly, and reduces the production cost.
