Abstract
The rubber-plastic sheet explosive is produced through a high explosive sheet producing process and formula in industrial explosive field. The method is characterized in that: the shaped high explosive is selected, petrochemical by-products are used as a binding agent, a curing agent is not required, and the shaped high explosive is prepared according to a certain proportion and rolled into the rubber-plastic sheet explosive. The preparation method is simple and convenient, the lowest limit detonation velocity of the rubber-plastic sheet explosive is 7000 m/s, the lowest critical detonation velocity is 5000 m/s, the limit thickness is 5 mm, the critical thickness is 1.5-2 mm, the impact sensitivity is 10%, the friction sensitivity is 14%, and the detonation point is 296 ℃.
Description
What the making method of rubber-plastic flake-type explosive related to is the prescription and the manufacture craft of a kind of plasticity flake-type explosive in the industrial explosive field.
Current, make the plasticity flake-type explosive and generally adopt resin or rubber to do binding agent and high explosive RDX, the rolling film-making of PETN twisting.Because the flake-type explosive of adopted solidifying agent, making has certain elasticity and intensity, need flake-type explosive be pasted on the workpiece with glue paste, do not add solidifying agent and have plasticity, but intensity is low, be difficult for pasting on the workpiece, and binding agent cost height, and scrap stock can not reclaim.(see " explosive processing " 1981.7, P.648～654, Zheng Zhemin etc.; The tabular explosive of EL-506-A that du pont company is produced, " Metable " explosive of Britain, US4293351.).
The objective of the invention is to:, enlarge high mangaenese steel explosion hardening kind and size range for improving flake-type explosive intensity; Binding agent with low cost is provided; The jet cutter that adopts rubber-plastic flake-type explosive to make plane wave generator and do blast cutting is used.
Main technical schemes of the present invention is: adopt typing high explosive mixed powder after Passivation Treatment and oily plastic cement twisting, rolling, cut-parts, do not taking place to make rubber-plastic flake-type explosive under the chemical reaction condition.
High explosive mixed powder in the technique scheme is made up of TNT, tetryl or RDX that (content of TNT is 0～42%, surplus is tetryl or RDX), the passivator of the mixed powder adding 1～5% of 60 order grades mixes under screening, sieve, the oily plastic cement 25～5% that will prepare is again rubbed evenly, and after two-roller mill repeatedly roll compacting make material in flakes, the scrap stock recovery of cutting out rolls into sheet again, makes rubber-plastic flake-type explosive.Oil plastic cement be by heavy oil, pitch, Atactic Polypropelene in 25～33%: 33～45: 17～27% ratio, under the condition of 180～200 ℃ of temperature, stir evenly in the pasty state, pour into after the passivation in the high explosive mixed powder, make its temperature remain on 70～80 ℃, (if RDX, its temperature is 100 ℃); Passivator can be graphite, paraffin.
Technical process of the present invention as shown in drawings
Advantage of the present invention is: rubber-plastic flake-type explosive has certain elasticity and has certain plasticity again, need not solidifying agent.Manufacture craft is easy, the binding agent starting material wide model of originating, low price.The lowest limit explosion velocity of rubber-plastic flake-type explosive is 7000 meter per seconds, and minimum critical explosion velocity is 5000m/second, and thickness limit is 5 millimeters, and critical thickness is 1.5～2 millimeters, and impact sensitivity is 10%, and friction sensitivity is 14%, and bursting point is 296 ℃, with one 8
#Detonator can detonate.
Embodiment: by the rubber-plastic flake-type explosive that above-mentioned technical process is made, its prescription and the performance middle sequence number 1 that sees the following form, sequence number 2, sequence number 3.
