Problems solved by technology

The performance of explosives is the key to the success of explosive compounding, and the agglomeration of explosives will directly affect the quality of explosive compounding, which will seriously lead to the scrapping of products
At present, industrial explosives such as ammonium oil explosives and emulsion explosives produced in China have been greatly improved through the efforts of predecessors, but explosives for explosive compounding need to add a large amount of inert additives to the original industrial explosives, so that the explosives will be seriously damaged. Agglomeration, and there are rare articles at home and abroad about improving the agglomeration phenomenon of explosives used for explosive compounding
At the same time, the original industrial explosives currently used in China are mainly modified ammonium oil explosives and powdery emulsion explosives. Although expanded ammonium nitrate explosives are cheap, they cannot be used in the field of explosive compounding due to their low performance.

Abstract

The present invention provides an explosive cladding explosive prepared from expanded ammonium nitrate explosive, calcium nitrate, graphite and magnesium stearate according to a certain ratio. The present invention also provides a method for preparing the explosive, and the method comprises weighing all raw materials and placing the raw materials in an automatic drug mixing machine to mix uniformly to obtain an explosive cladding explosive. Further, the present invention also provides a method for preparing explosive clad plates by using the explosive, and the method comprises: laying a clad plate on the top of a baseplate, and laying support columns between the clad plate and the baseplate; positioning an explosive frame on the clad plate, overlying the explosive inside the explosive frame, and placing a detonating primer on the explosive; and detonating the explosive by using the detonating primer to obtain the explosive clad plate. The explosive cladding explosive of the invention is good in formula design, simple in a blending method, low in cost, excellent in performance and anti-caking performance; and the explosive clad plate prepared by using the explosive cladding explosive of the invention has a high interlaminar bonding rate and high combination strength, and is for large-scale industrial production.

Description

Technical field [0001] The invention belongs to the technical field of industrial explosive materials, and specifically relates to an explosive for explosive composites and a preparation method and application thereof. Background technique [0002] Explosive compounding technology is large-area layered explosive welding. The products produced by this technology can be used in many fields such as thermal power plant chimney lining, nuclear power condenser tube sheet, chemical reaction vessel, etc., with high efficiency and low pollution, and has been widely used Its application in the field of metal processing has created tremendous social value. The performance of explosives is the key to the success of explosive recombination. The agglomeration of explosives will directly affect the quality of explosive recombination, and severely lead to product scrapping. At present, domestically produced industrial explosives such as ammonium explosives and emulsion explosives have been grea...
