Description

Pyroteknisk lakk. Pyrotechnic varnish.

Foreliggende oppfinnelse angår en pyroteknisk lakk for The present invention relates to a pyrotechnic varnish for

anvendelse som tennmaterial for faste drivkrutt-blokker og ladninger for gassutviklere. use as ignition material for solid propellant blocks and charges for gas developers.

Det særegne ved den pyrotekniske lakk i henhold til oppfinnelsen er at den består av en kollodiumlosning på basis av nitrocellulose og/eller nitroglycerol i et keton, og et meget kraftig tennkrutt dispergert i den nevnte kollodiumlosning, idet tennkruttet er valgt fra gruppen bestående av termittkrutt (blandinger av kaliumperklorat, jernoksyd og magnesium), svartkrutt og zirkoniumkrutt (zirkonium, bariumkromat, ammoniumperklorat og ammonium-bikrornat). The distinctive feature of the pyrotechnic varnish according to the invention is that it consists of a collodion solution based on nitrocellulose and/or nitroglycerol in a ketone, and a very powerful gunpowder dispersed in the aforementioned collodion solution, the gunpowder being selected from the group consisting of thermite gunpowder ( mixtures of potassium perchlorate, iron oxide and magnesium), black powder and zirconium powder (zirconium, barium chromate, ammonium perchlorate and ammonium bicarbonate).

Mengdeforholdet mellom tennkrutt og kollodium-losning i den pyrotekniske lakk er 5-99, 5%, fortrinnsvis 40 - 60 vektprosent tennkrutt og 95 - 0,5%, fortrinnsvis 60 - 40 vektprosent kollodiumlosning. The quantity ratio between gunpowder and collodion solution in the pyrotechnic varnish is 5-99.5%, preferably 40 - 60% by weight tinpowder and 95 - 0.5%, preferably 60 - 40% by weight collodion solution.

Kollodium-losningen inneholder fortrinnsvis 75 vektprosent nitrocellulose og/eller nitroglycerol og 25 vektprosent keton. Ennvidere bor tennkruttet ha en partikkelstorrelse mindre enn The collodion solution preferably contains 75% by weight of nitrocellulose and/or nitroglycerol and 25% by weight of ketone. Furthermore, the gunpowder must have a particle size smaller than

500 mikron. 500 microns.

For fremstilling av ferdige drivkruttblokker overstrykes over-flaten av drivkruttblokkene, som skal antennes, med den pyrotekniske lakk, og losningsmidlet i det påforte lakkskikt fordampes. For the production of finished propellant blocks, the surface of the propellant blocks, which are to be ignited, is coated with the pyrotechnic varnish, and the solvent in the applied varnish layer is evaporated.

Den således erholdte pyrotekniske lakk kan med fordel erstatte den tidligere anvendte omhylling med svartkrutt festet ved liming til den flate av drivkruttblokken som skal antennes hvorved en svikt i sammenklebningen kunne medfore uheldig virkning på systemet for styring av tenningen. The pyrotechnic varnish thus obtained can advantageously replace the previously used covering with black powder attached by gluing to the surface of the propellant block to be ignited, whereby a failure in the bonding could have an adverse effect on the system for controlling the ignition.

Den pyrotekniske lakk kan likeledes anvendes for å tilveiebringe pyrotekniske ladninger for gassutviklere av den type som er beskrevet i franske patentskrifter nr. 2.116.947 og 2.116.948. The pyrotechnic varnish can likewise be used to provide pyrotechnic charges for gas developers of the type described in French patent documents Nos. 2,116,947 and 2,116,948.

For dette formål påstrykes delvis eller fullstendig yttersiden For this purpose, the outer side is partially or completely ironed on

av beholderen for fordampbar væske med den pyrotekniske lakk, of the container for evaporable liquid with the pyrotechnic varnish,

og ketonlosningsmidlet i det således erholdte lakkskikt fordampes. and the ketone solvent in the lacquer layer thus obtained is evaporated.

Fordelene med den nye pyrotekniske lakk er mange: The advantages of the new pyrotechnic paint are many:

- den nodvendiggjor ikke varmeherding eller polymerisasjon, den er stabil ved lagring i tette beholdere, - it does not require heat curing or polymerisation, it is stable when stored in tight containers,

man kan lett influere på dens forbrenningshastighet ved å one can easily influence its burning rate by

modifisere mengdeforholdet av ladning og/eller ved å forandre arten av kollodium-losning eller tennkruttet. modifying the quantity ratio of charge and/or by changing the nature of the collodion solution or the gunpowder.

Oppfinnelsen illustreres ytterligere av de etterfølgende utforelseseksempler med henvisning til de vedfoyde tegninger hvori:' Fig. 1 er et loddrett sideriss gjennom en drivkruttblokk utstyrt med et pyroteknisk lakkovertrekk ifolge oppfinnelsen, The invention is further illustrated by the following exemplary embodiments with reference to the attached drawings in which: Fig. 1 is a vertical side view through a propellant block equipped with a pyrotechnic lacquer coating according to the invention,

Den således erholdte pyrotekniske lakk ble anvendt for ved påstrykning å tilveiebringe et tennmaterial på en "Epictete"-drivkruttblokk (myknet nitrocellulose og nitroglycerin) med frontforbrenning, og som vist i fig. 1 i loddrett sidesnitt og vist sett forfra i fig. 2. The pyrotechnic varnish thus obtained was used to provide, by application, an ignition material on an "Epictete" propellant block (softened nitrocellulose and nitroglycerin) with front combustion, and as shown in fig. 1 in vertical side section and shown from the front in fig. 2.

Den sylindriske drivkruttblokk 1 har en diameter på 78 mm, er gjennomhullet med en sylindrisk aksial kanal 2 med diameter 1,5 The cylindrical propellant block 1 has a diameter of 78 mm, is pierced with a cylindrical axial channel 2 with a diameter of 1.5

mm og er overtrukket med et skikt av en inhibitor 3 på sideveggen, i kanalen og på dens forside. På blokkens bakside la er det påfort et skikt 4 av den ovenfor fremstilte pyrotekniske lakk, idet 5 g av denne lakk er påstroket jevnt over et ringformet område med ytre diameter 60 mm og indre diameter 10 mm, og således fullstendig adskilt fra blokkens aksiale kanal 2. mm and is coated with a layer of an inhibitor 3 on the side wall, in the channel and on its front. On the backside 1a of the block, a layer 4 of the pyrotechnic varnish prepared above is applied, 5 g of this varnish being applied evenly over a ring-shaped area with an outer diameter of 60 mm and an inner diameter of 10 mm, and thus completely separated from the block's axial channel 2 .

Lakkskiktet torres derett.er i klimarom ved 21 - 2 9°C og 30 - 40% relativ fuktighet i lopet av noen timer, hvorved det på drivkruttblokken erholdes et skikt av tennmaterial med 1 mm tykkelse. The varnish layer is then dried in an air-conditioned room at 21 - 29°C and 30 - 40% relative humidity over the course of a few hours, whereby a layer of incendiary material with a thickness of 1 mm is obtained on the propellant block.

The results are presented graphically in fig. 4. Compilation of the graphic representations in fig. 3 and 4 show an identical arrangement of the propellant and the mixture of gunpowder and collodion in the vacuum test.

Forholdet ved aldring av tennmaterialet erholdt fra den pyrotekniske lakk vises klart ved den såkalte "cube-test". The aging of the ignition material obtained from the pyrotechnic varnish is clearly shown by the so-called "cube test".

Forsoket er basert på aldring i 2 - 6 måneder ved 60°C. Ved forsoket anvendes det 4 terninger med 25 mm sider hvis ene flate er fullstendig dekket med den pyrotekniske lakk med samme tykkelse som det lakkskikt som ble påfort drivkruttblokken. The experiment is based on aging for 2 - 6 months at 60°C. In the experiment, 4 cubes with 25 mm sides are used, one surface of which is completely covered with the pyrotechnic varnish of the same thickness as the varnish layer that was applied to the propellant block.

En provecyklus omfatter: A trial cycle includes:

a) 13 timer i varmeskap med termostat ved den innstilte temperatur + 1,5°C, b) uttagning fra varmeskapet i 6 timer, hvorunder hver terning ble undersokt visuelt og radiografisk med hensyn til grenseflaten a) 13 hours in a heating cabinet with a thermostat at the set temperature + 1.5°C, b) removal from the heating cabinet for 6 hours, during which each cube was examined visually and radiographically with regard to the interface

mellom drivkruttblokken og tennmaterialet. between the propellant block and the ignition material.

De oppnådde resultater etter 22 cykluser ved 60°C er som folger: Det ble ikke observert noen losgjoring eller svikt av tennmaterial-skiktet, og ingen sprekkdannelser i drivkruttblokken. The results obtained after 22 cycles at 60°C are as follows: No loosening or failure of the igniter material layer was observed, and no cracking was observed in the propellant block.
