Abstract

Explosive material consisting of one or several self-detonating explosives, such as PETN, HMX, TNT or RDX, desensitized by wax or water and one or several inert materials. The invention is characterized in that the inert material or a part thereof consists of a rubber of the type silicone rubber or latex rubber, which inert material constitutes matrix or binding agent, and that components comprised after being mixed together constitute a compound, which can be cast, extruded or rolled-out.

Description

460 901 och utmärkes av att det inerta materialet eller en del av detta utgöres av ett gummi av typen silikongummi eller latexgummi, vilket ínerta material utgör matris eller bindemedel samt av att ingående komponenter efter samman- blandning utgör en gjutbar, extruderbar eller utvalsbar massa. 460 901 and is characterized in that the inert material or a part thereof consists of a rubber of the type silicone rubber or latex rubber, which inert material constitutes a matrix or binder and in that constituent components after mixing form a castable, extrudable or selectable mass.

Som matris och bindemedel kan således antingen silikongummi eller latexgummi användas. Båda materialen är miljövänliga, ej giftiga och ger inga farliga temperaturhöjningar vid härdningen. De är helt inerta i förhållande till sprängämnen såsom PETN, TNT, HHX eller RDX. Vid gjutning med silikongummi eller latex kan t.ex. vaxflegmatiserad PETN användas.Thus, either silicone rubber or latex rubber can be used as matrix and binder. Both materials are environmentally friendly, non-toxic and do not cause dangerous temperature increases during curing. They are completely inert to explosives such as PETN, TNT, HHX or RDX. When casting with silicone rubber or latex, e.g. wax phlegmatized PETN is used.

Vid gjutning med latex kan även vattenflegmatiserade sprängämnen användas.When casting with latex, water phlegmatized explosives can also be used.

Latexgummi är emellertid begränsat till gjutning av tunna skikt då avdunst- ning av vatten måste kunna ske vid härdningen. Tjockare skikt kan dock er- hållas genom att flera härdade tunna skikt staplas eller lindas på varandra.However, latex rubber is limited to the casting of thin layers as evaporation of water must be possible during curing. Thicker layers can, however, be obtained by stacking or wrapping several hardened thin layers on top of each other.

Såväl när det gäller silikon- som latexgummi kan ytterligare tillsatser ske t.ex. metallpulver för reglering av tätheten eller mikrosfärer av plast eller glas för reglering av initierbarheten.In the case of both silicone and latex rubber, additional additives can be made, e.g. metal powders for regulating the density or microspheres of plastic or glass for regulating the initiability.

Nedan återges ett antal exempel på sprängämnesmateríal enligt uppfinningen.Below are a number of examples of explosive material according to the invention.

Exempel I Följande ingredienser uppvägdes och blandades: 37,62 vaxflegmatiserad PETN (72 vax) l5% järnpulver 6,Å% mikrosfärer av glas älï silikongummi Blandningen gjöts i formar till 25mm skikt. De stelnade sprängmaterialkropparna detonerade med hastigheten 3700 m/s Exempel 2 Följande ingredienser uppvägdes och blandades: 87% vaxflegmatiserad PETN 13% latex Blandningen gjöts till skikttjockleken Bmm. Remsor om l6mm bredd initierades med sprängkapsel och detonerade med hastigheten 7800 m/s. a 3 i 460 901 Exemgel 3 En blandning enligt exempel l gjöts i 3 mm skikt.Example I The following ingredients were weighed and mixed: 37.62 wax phlegmatized PETN (72 wax) 15% iron powder 6.0% microspheres of glass or silicone rubber The mixture was cast in molds into 25 mm layers. The solidified explosive bodies detonated at a speed of 3700 m / s Example 2 The following ingredients were weighed and mixed: 87% wax phlegmatized PETN 13% latex The mixture was cast to the layer thickness Bmm. Strips of l6mm width were initiated with detonator and detonated at a speed of 7800 m / s. a 3 in 460 901 Example gel 3 A mixture according to example 1 was cast in 3 mm layers.

En stapel av S st remsor, 16 mm breda, detonerades med en hastighet av 3500 m/s.A stack of S strips, 16 mm wide, was detonated at a speed of 3500 m / s.

Exemgel Å En blandning av: #32 vattenflegmatlserad HHX 13,72 järnpulver 5.92 mikrosfärer av glas Blandningen gjöts på gasväv till ett band av 3 mm tjocklek och tâcktes efter gjutníngen av ytterligare en gasväv. Gasväven var avsedd som mekanisk armering. 5 st remsor 50 mm breda staplades på varandra och initierades. Detonationens hastighet uppmättes till 3ü00 m/s. Då en annan S0 mm bred remsa iindades S på varandra liggande varv runt ett papprör av l00 mm diameter och detonerades erhölls samma detonationshastighet.Example gel Å A mixture of: # 32 water-phlegmated HHX 13.72 iron powder 5.92 microspheres of glass The mixture was cast on gauze to a strip of 3 mm thickness and covered after the casting of another gauze. The gauze was intended as mechanical reinforcement. 5 strips 50 mm wide were stacked on top of each other and initiated. The velocity of the detonation was measured at 3ü00 m / s. When another S0 mm wide strip was wound S superimposed turns around a cardboard tube of 100 mm diameter and detonated, the same detonation rate was obtained.

Med gummi av silikon eller latextyp kan således sprängämnesmaterial med olika tjocklekar och egenskaper på ett enkelt sätt tillverkas. Laddningar av den typ som framställts enligt receptet enligt exempel I ovan har visat sig bered- villigt detonera på ett vattendjup av H50 meter, nedsänkta i en vattenfylld gruva. Även laddningar, som legat nedsänkta under en tid av en månad kunde utan problem detoneras.Thus, with silicone or latex type rubber, explosive materials with different thicknesses and properties can be manufactured in a simple manner. Charges of the type prepared according to the recipe according to Example I above have been shown to detonate readily at a water depth of H50 meters, immersed in a water-filled mine. Charges that had been immersed for a period of one month could also be detonated without any problems.

Enligt en föredragen utföríngsform utgöres det lnerta materialet förutom nämnda gummi, som nämnts, av ett metallpuiver och/eller ihåliga mikrosfärer av glas eller plast.According to a preferred embodiment, in addition to said rubber, as mentioned, the inner material consists of a metal powder and / or hollow microspheres of glass or plastic.

Enligt ytterligare en föredragen utföringsform förefínns en mekanisk armering av en väv, trådar eller fibrer av textllmaterial eller glasfibrer íngjuten i sprängämnesmaterialet.According to a further preferred embodiment, there is a mechanical reinforcement of a fabric, threads or fibers of textile material or glass fibers embedded in the explosive material.

Genom utförda försök har uppfinnaren konstaterat att vid sprängämnesmaterial innehållande latex kan en snabbstelning på ytan ske om materialet bringas i kontakt med aceton, el. alkohol. Så har till exempel snören med en diameter av 7 m extruderats ned i ett bad av aceton._På grund av ytstelnidgen blev snörena så hanterbara att de kunde upplindas på en torkvinda. Detta för- hållande underlättar avsevärt en massproduktion av sprängämnesmaterialet. 460 901 Enligt en föredragen utförlngsform är sprängämnesmaterlalet därför så utfört att, för det fall matrisen eller bíndemedlet utgöres av latex, en ytlig. snabbstelning av sprängämnesmaterlalet skett genom påverkan av en koagulerande vätska såsom aceton eller alkohol.Through experiments performed, the inventor has found that in the case of explosive material containing latex, a rapid solidification on the surface can take place if the material is brought into contact with acetone, el. alcohol. For example, the strings with a diameter of 7 m have been extruded into a bath of acetone. Due to the surface stiffness, the strings became so manageable that they could be wound on a drying wind. This condition considerably facilitates mass production of the explosive material. 460 901 According to a preferred embodiment, the explosive material is therefore designed in such a way that, in the case where the matrix or binder consists of latex, a surface. rapid solidification of the explosive material occurred by the action of a coagulating liquid such as acetone or alcohol.
