Description
Foreliggende oppfinnelse vedrører et vannresistent elastisk eksplosivmateriale. The present invention relates to a water-resistant elastic explosive material.
Det er kjent at eksplosivmaterialer inneholdende et selvdetonerende sprengstoff, som f.eks. PETN, HMX, EDX eller TNT, kan fremstilles med støpeplast som matriks. It is known that explosive materials containing a self-detonating explosive, such as PETN, HMX, EDX or TNT can be produced with molded plastic as a matrix.
Fremstillingen av disse såkalte PBX-eksplosivene er imidlertid dyr og komplisert, på grunn av det faktum at de selvdetonerende sprengstoffene må tilsettes i sensibilisert tilstand, fordi herdeprosessen for plastmaterialet påvirkes i betydelig grad av eksisterende avsensibiliseringsmidler, så som voks, olje eller vann. However, the production of these so-called PBX explosives is expensive and complicated, due to the fact that the self-detonating explosives must be added in a sensitized state, because the curing process of the plastic material is significantly affected by existing desensitizing agents, such as wax, oil or water.
På grunn av deres høye sensibilitet og farene forbundet med dette er håndteringen av sensibiliserte eksplosiver komplisert og krever spesielle lokaler og spesielt utstyr, hvilket begrenser produksj onshastigheten. Because of their high sensitivity and the dangers associated with this, the handling of sensitized explosives is complicated and requires special premises and special equipment, which limits the production rate.
De støpbare plasttypene er som regel per se helseskadelige og krever derfor effektiv beskyttelsesutstyr. Når temperaturen i støpeforbindelsen ikke holdes under nøyaktig kontroll, kan lokale temperaturøkninger være så høye at eksplosivet reagerer hvilket resulterer i en eksplosjon. PBX-eksplosivene gir ved detonering eller forbrenning også produkter som er helseskadelige eller korrosive. The moldable types of plastic are generally per se harmful to health and therefore require effective protective equipment. When the temperature of the casting compound is not kept under precise control, local temperature increases can be so high that the explosive reacts resulting in an explosion. When detonated or burned, the PBX explosives also produce products that are harmful to health or corrosive.
Eksplosivmaterialet ifølge foreliggende oppfinnelse kan fremstilles og benyttes uten de ovenfor nevnte ulempene og farene. The explosive material according to the present invention can be produced and used without the above-mentioned disadvantages and dangers.
Et ønske er å muliggjøre arbeidet med avsensibiliserte eksplosiver. Det er imidlertid ikke mulig å anvende støpbare plasttyper som matriksmateriale når avsensibiliseringsmidlet f.eks. er olje eller voks, fordi slike plasttyper oppløser avsensibiliseringsmidlet. Vann kan også benyttes som avsensibiliseringsmiddel, men f.eks. gir vann-avsensibilisert pentyl sammen med en formbar plast opphav til en betydelig volumøkning. One wish is to enable work with desensitized explosives. However, it is not possible to use moldable plastics as matrix material when the desensitiser e.g. is oil or wax, because such types of plastic dissolve the desensitiser. Water can also be used as a desensitizing agent, but e.g. water-desensitized pentyl together with a malleable plastic gives rise to a significant increase in volume.
Foreliggende oppfinnelse gjør det imidlertid mulig å arbeide med avsensibiliserte eksplosiver for å fremstille et vannresistent elastisk eksplosivmateriale. The present invention, however, makes it possible to work with desensitized explosives to produce a water-resistant elastic explosive material.
Foreliggende oppfinnelse vedrører følgelig et eksplosivmateriale bestående av et eller flere selvdetonerende sprengstoffer avsensibilisert med voks eller vann, så som PETN, HMX, TNT eller RDX, og ett eller flere inerte materialer, og er kjennetegnet ved at det inerte materialet helt eller delvis består av en gummi av typen silikongummi eller lateksgummi, hvilket inerte materiale utgjør matriks- eller bindemidlet, og at komponentene etter sammenblanding utgjør en forbindelse, som kan støpes, ekstruderes eXler utvalses. The present invention therefore relates to an explosive material consisting of one or more self-detonating explosives desensitized with wax or water, such as PETN, HMX, TNT or RDX, and one or more inert materials, and is characterized in that the inert material consists wholly or partly of a rubber of the type silicone rubber or latex rubber, which inert material forms the matrix or binder, and that the components form a compound after mixing, which can be molded, extruded or rolled.
Som matriks og bindemiddel kan følgelig enten silikongummi . eller lateksgummi anvendes. Begge disse materialene er uskadelige for omgivelsene, ikke-toksiske og gir ikke opphav til farlige temperaturøkninger ved herding. De er fullstendig inerte i forbindelse med eksplosiver så som PETN, TNT, HMX eller RDX. Ved støping med silikongummi eller lateks kan f.eks. voks-avsensibilisert PETN benyttes. Consequently, either silicone rubber can be used as matrix and binder. or latex rubber is used. Both of these materials are harmless to the environment, non-toxic and do not give rise to dangerous temperature increases during curing. They are completely inert in connection with explosives such as PETN, TNT, HMX or RDX. When casting with silicone rubber or latex, e.g. wax-desensitized PETN is used.
Ved støping med lateks kan også vann-avsensibiliserte eksplosiver anvendes. Lateksgummi er imidlertid begrenset til støping av tynne lag, fordi det må være mulig for vannet å fordampe ved herdingen. Lag av større tykkelse kan imidlertid oppnås ved å stable eller tvinne flere herdede tynne lag på hverandre. I tilfelle med silikon-, så vel som lateksgummi, kan ytterligere tilsatser foretas, f.eks. metallpulver for å regulere densiteten eller mikrosfærer av plast eller glass for å kontrollere initieringskapasiteten. When molding with latex, water-desensitized explosives can also be used. However, latex rubber is limited to casting thin layers, because it must be possible for the water to evaporate during curing. However, layers of greater thickness can be obtained by stacking or twisting several hardened thin layers on top of each other. In the case of silicone as well as latex rubber, further additions can be made, e.g. metal powder to regulate the density or plastic or glass microspheres to control the initiation capacity.
Noen eksempler på eksplosivmaterialer ifølge oppfinnelser er beskrevet i det følgende. Some examples of explosive materials according to inventions are described in the following.
Eksempel 1 Example 1
Følgende bestanddeler ble utveid og blandet: The following ingredients were weighed out and mixed:
37,6$ voks-avsensibilisert PETN ( 7% voks) 37.6$ wax-desensitized PETN (7% wax)
15% jernpulver 15% iron powder
b, A% mikrosfærer av glass b, A% glass microspheres
41$ silikongummi 41$ silicone rubber
Blandingen ble støpt i former til lag av tykkelse 25 mm. De størknede eksplosivlegemene detonerte med hastighet 7800 m/sek. The mixture was cast in molds into layers of thickness 25 mm. The solidified explosive bodies detonated at a speed of 7,800 m/sec.
Eksempel 2 Example 2
De følgende bestanddelene ble utveid og blandet: The following ingredients were weighed out and mixed:
87% voks-avsensibilisert PETN 87% wax-desensitized PETN
13% lateks 13% latex
Blandingen ble støpt til lag av tykkelse 3 mm. Bånd av 16 mm bredde ble initiert med sprengkapsel og detonert med hastighet 7800 m/sek. The mixture was molded into layers of thickness 3 mm. Strips of 16 mm width were initiated with a blasting cap and detonated at a speed of 7,800 m/sec.
Eksempel 3 Example 3
En blanding ifølge eksempel 1 ble støpt til lag av tykkelse 3 mm. En stabel av 5 bånd, 16 mm brede, ble detonert med en hastighet på 3500 m/sek. A mixture according to example 1 was cast into a layer of thickness 3 mm. A stack of 5 bands, 16 mm wide, was detonated at a speed of 3500 m/sec.
Eksempel 4 Example 4
En blanding av: A mixture of:
43$ vann-avsensibilisert HMX 43$ water-desensitized HMX
13,7$ jernpulver 13.7$ iron powder
5,9$ mikrosfærer av glass 5.9$ glass microspheres
Blandingen ble støpt på gas til en bane av 3 mm tykkelse, og ble etter støping dekket med et ytterligere lag gas. Gasen var ment som mekanisk forsterkning. 5 bånd av bredde 50 mm ble stablet på hverandre og initiert. Detoneringshastigheten ble målt til 3400 m/sek. Når et annet bånd av bredde 50 mm ble tvunnet fem ganger på hverandre rundt et papprør av diameter 100 mm og detonert, ble den samme detoneringshastigheten oppnådd. The mixture was cast on gas to a web of 3 mm thickness, and after casting was covered with a further layer of gas. The gas was intended as mechanical reinforcement. 5 strips of width 50 mm were stacked on top of each other and initiated. The detonation speed was measured at 3400 m/sec. When another band of width 50 mm was twisted five times on each other around a cardboard tube of diameter 100 mm and detonated, the same detonation rate was obtained.
Det er følgelig mulig å fremstille eksplosivmateriale med gummi av silikon eller latekstypen på en enkel måte, hvor materialet har forskjellige tykkelser og egenskaper. Satser av typen fremstilt ifølge formelen angitt i eksempel 1 har vist seg å detonere lett ved en vanndybde på 450 m, neddykket i en vannfylt mine. Selv ladninger som hadde ligget neddykket i et tidsrom på en måned, kunne detoneres uten problem. It is therefore possible to produce explosive material with silicone or latex type rubber in a simple way, where the material has different thicknesses and properties. Charges of the type prepared according to the formula given in Example 1 have been found to detonate easily at a water depth of 450 m, submerged in a water-filled mine. Even charges that had been submerged for a month could be detonated without problem.
Ifølge en foretrukket utførelse består det inerte materialet, som nevnt, i tillegg til nevnte gummi, av et metallpulver og/eller hule mikrosfærer av glass eller plast. According to a preferred embodiment, the inert material, as mentioned, in addition to said rubber, consists of a metal powder and/or hollow microspheres of glass or plastic.
Ifølge en annen foretrukket utførelse er en mekanisk armering av et stoff, tråder eller fibrer av tekstilmateriale eller glassfibrer, anbrakt innstøpt i eksplosivmaterialet. According to another preferred embodiment, a mechanical reinforcement of a substance, threads or fibers of textile material or glass fibers, is placed embedded in the explosive material.
Det er videre ved forsøk oppdaget at ved eksplosivmaterialer som inneholder lateks kan rask størkning på overflaten finne sted når materialet bringes i kontakt med aceton eller alkohol. Tråder med en diameter på 7 mm ble f.eks. eksplodert ned i et bad av aceton. På grunn av overflatestørkningen ble trådene så håndterbare at de kunne vinnes opp på en tørke-spole. Denne omstendigheten letter i betydelig grad en massefremstilling av eksplosivmaterialet. It has also been discovered during experiments that with explosive materials containing latex, rapid solidification on the surface can take place when the material is brought into contact with acetone or alcohol. Wires with a diameter of 7 mm were e.g. exploded into a bath of acetone. Due to the surface solidification, the threads became so manageable that they could be wound on a drying reel. This circumstance greatly facilitates mass production of the explosive material.
Ifølge en foretrukket utførelse fremstilles følgelig eksplosivmaterialet på en slik måte at, når matriks- eller bindemidlet består av lateks, finner rask størkning på overflaten av eksplosivmaterialet sted ved hjelp av virkningen av en koaguleringsvæske, så som aceton eller alkohol. Accordingly, according to a preferred embodiment, the explosive material is produced in such a way that, when the matrix or binder consists of latex, rapid solidification on the surface of the explosive material takes place by means of the action of a coagulating liquid, such as acetone or alcohol.
