Description

455 478 2 dagar måste bära sina skyddsdräkter, varför skyddsdräkter av detta tidigare kända, icke-luftgenomsläppliga material i praktiskt bruk icke är användbara, eftersom den för huden nödvändiga luftväxlingen ej kan åstadkommas. För att eliminera dessa problem är det genom DE-AS 2 829 599 och 2 843 974 känt, att den såsom ytterskikt fungerande textilvävnaden göres icke- antändlig. att mellan ytterskiktet och det inre skiktet insättes ett fiberskikt av mineralfiber och att det inre skiktet framställes av ett luftgenomsläppligt skummaterial, vars porer innehåller partiklar av aktivt kol, varvid mellan textilväven och skiktet av mineralfiber kan vara anordnat ytterligare ett luftgenomsläppligt, poröst, vattentätt skikt. 455 478 2 days must wear their protective suits, so protective suits of this previously known, non-air-permeable material are not useful in practical use, since the air exchange necessary for the skin cannot be achieved. In order to eliminate these problems, it is known from DE-AS 2 829 599 and 2 843 974 that the textile fabric acting as an outer layer is made non-flammable. that a fibrous layer of mineral fiber is inserted between the outer layer and the inner layer and that the inner layer is made of an air-permeable foam material, the pores of which contain particles of activated carbon, whereby another air-permeable, porous, waterproof layer can be arranged between the textile fabric and the mineral fiber layer.

Det på så sätt utformade, flera skikt innefattande la- minatet utmärker sig genom en relativt hög bekvämlighet vid användningen, när man aktivt söker undvika extremt höga, kortvariga värmepåkänningar.The laminate, designed in this way, comprises several layers with a relatively high level of convenience in use, when actively seeking to avoid extremely high, short-term thermal stresses.

En uppgift i samband med föreliggande uppfinning har därför varit att söka åstadkomma ett flerskiktigt, laminerat material, särskilt för skyddskläder, vilket utmärker sig genom hög materialhållbarhet gentemot nukleära värmeblixtar.A task in connection with the present invention has therefore been to seek to provide a multilayer, laminated material, especially for protective clothing, which is characterized by high material durability against nuclear thermal flashes.

Uppgiften löses i samband med ett laminerat material av inledningsvis beskrivet slag enligt föreliggande uppfinning genom att spärrskiktet består av ett ljusreflekterande, vit- blekt skikt av textilmaterial.The object is solved in connection with a laminated material of the kind initially described according to the present invention in that the barrier layer consists of a light-reflecting, white-bleached layer of textile material.

Det reflekterande skiktet är företrädesvis en vitblekt bomullsväv, vilken dessutom på sin mot det yttre skiktet vända yta kan vara belagd med ett skikt avi.huvudsak sfäriska glas- pärlor el.dyl., vilka har en diameter av minst 0,5 pm och högst 7,0 pm.The reflective layer is preferably a white-bleached cotton fabric, which in addition can be coated on its surface facing the outer layer with a layer of mainly spherical glass beads or the like, which have a diameter of at least 0.5 μm and at most 7 μm. , 0 pm.

Bekvämligheten vid bärandet av en skyddsdräkt, som är framställd av det laminerade materialet enligt uppfinningen nedsättes,ej på grund av att det reflekterande skiktet_är luftgenomsläppligt. Å andra sidan har det helt överraskande visat sig, att materialets energireflekterande förmåga är mycket hög och kan ytterligare höjas avsevärt genom det här beskrivna skiktet av glaspärlor. Det laminerade materialet enligt uppfinningen är därigenom synnerligen väl lämpat att användas i militära skyddsdräkter, eftersom materialet kan 455 478 3 uthärda kortvariga nukleära värmeblixtar.The comfort in wearing a protective suit made from the laminated material of the invention is reduced, not because the reflective layer is air permeable. On the other hand, it has quite surprisingly been found that the energy-reflecting ability of the material is very high and can be further increased considerably by the layer of glass beads described here. The laminated material according to the invention is thereby particularly well suited for use in military protective suits, since the material can withstand short-term nuclear thermal flashes.

Det reflekterande skiktet enligt uppfinningen tjänar företrädesvis såsom ersättning för det genom DE-AS 2 829 599 kända skiktet av mineralfiber mellan det yttre skiktet av textilmaterial och det luftgenomsläppliga, värmedämpande inre skiktet. Enligt uppfinningen kan emellertid dessutom det genom DE-AS 2 829 599 kända míneralfiberskiktet vara anordnat, varvid det reflekterande skiktet är anordnat mellan ytter- skiktet av textilmaterial och mineralfiberskiktet. Konstruk- tionen och sammansättningen av mineralfiberskiktet framgår av DE-AS 2 829 599.The reflective layer according to the invention preferably serves as a replacement for the layer of mineral fiber known from DE-AS 2 829 599 between the outer layer of textile material and the air-permeable, heat-absorbing inner layer. According to the invention, however, in addition the mineral fiber layer known from DE-AS 2 829 599 can be arranged, the reflective layer being arranged between the outer layer of textile material and the mineral fiber layer. The construction and composition of the mineral fiber layer is shown in DE-AS 2,829,599.

Dessutom kan också vara anordnat ett luftgenomsläppligt, poröst men vattentätt skikt mellan det reflekterande skiktet och mineralfiberskiktet enligt DE-AS 2 843 974.In addition, an air-permeable, porous but waterproof layer can also be arranged between the reflective layer and the mineral fiber layer according to DE-AS 2 843 974.

Av väsentlig betydelse är, att det reflekterande skiktet på sin mot det yttre skiktet vända yta är "b1ändvitt“ eller "bländsljustï Detta kan exempelvis också åstadkommas genom att den mot det yttre skiktet vända ytan är försedd med en silverbeläggning eller är silverfärgad eller också är aluminerad. Det här använda uttrycket "blekt" skall alltså motsvara “bländvitt“ resp. "bländljust".It is essential that the reflective layer on its surface facing the outer layer is "dazzling white" or "glare". This can also be achieved, for example, by the surface facing the outer layer being provided with a silver coating or being silver-colored or also aluminized. . The term "bleached" used here must therefore correspond to "dazzling white" resp. "dazzling".

De i det föregående beskrivna glaspärlorna är företrädes- vis klistrade på det reflekterande skiktets mot det yttre skiktet vända yta och på sådant sätt, att luftgenomsläpplig- heten bibehålles praktiskt_taget intakt. På grund av den före- dragna användningen av det laminerade materialet enligt uppfinningen användes därvid ett icke-antändligt bindemedel.The glass beads described above are preferably adhered to the surface of the reflective layer facing the outer layer and in such a way that the air permeability is maintained practically intact. Due to the preferred use of the laminated material according to the invention, a non-flammable binder was used.

Det reflekterande skiktet kan vara löst eller fast anordnat mellan det inre skiktet och det yttre skiktet. I sistnämnda fall är det reflekterande skiktet antingen fast- klistrat, fastsvetsat eller fastpressat på det inre skiktet.The reflective layer may be loose or fixedly arranged between the inner layer and the outer layer. In the latter case, the reflective layer is either glued, welded or pressed onto the inner layer.

När det inre skiktet på genom DE-AS 2 829 599 känt sätt utgöres av ett skikt av luftgenomsläppligt skummaterial, vars porer innehåller partiklar av aktivt kol, är det reflekterande skiktet företrädesvis bundet (ty. "bondiert") på det inre skiktet.When the inner layer in a manner known from DE-AS 2 829 599 consists of a layer of air-permeable foam material, the pores of which contain particles of activated carbon, the reflective layer is preferably bonded (ie "bondiert") to the inner layer.

När det reflekterande skiktet är löst anordnat mellan det yttre skiktet-och det inre skiktet resp. det inre filter- 455 478 4 skiktet, är det reflekterande skiktet företrädesvis fastsytt mellan dessa båda skikt.When the reflective layer is loosely arranged between the outer layer and the inner layer resp. the inner filter layer, the reflective layer is preferably sewn between these two layers.

Konstruktionen och sammansättningen av det yttre skiktet av textilmaterial och det luftgenomsläppliga, värmedämpande inre skiktet är tidigare kända genom DE-AS 2 829 599.The construction and composition of the outer layer of textile material and the air-permeable, heat-absorbing inner layer are previously known from DE-AS 2 829 599.

Det är i själva verket också möjligt att framställa skyddsdräktsdetaljer, t.ex. stövlar el.dyl" såsom formelement av det här beskrivna materialet. Företrädesvis framställes emellertid materialet i form av en bana, som sedan kan vidare- bearbetas till de önskade beklädnadsdetaljerna.In fact, it is also possible to produce protective suit details, e.g. boots or the like "as molding elements of the material described here. Preferably, however, the material is produced in the form of a web, which can then be further processed into the desired cladding details.

Slutligen bör även framhållas, att det laminerade materialet enligt uppfinningen visserligen är speciellt lämpat att användas för skyddsdräkter av olika slag, men det är icke begränsat till sådan användning. Det är även möjligt att av materialet framställa påsar för att tsex. förvara värmekäns- liga föremål, såsom t.ex. bärbara radioapparater, spräng- patroner el.dyl” men materialet är också användbart för övertäckande ytor, sovsäckar, tältbottnar och motsvarande i samband med framställningen och utrustningen av ställningar, som skall användas för att ge skydd gentemot nukleära värme- blixtar.Finally, it should also be pointed out that although the laminated material according to the invention is particularly suitable for use in protective suits of various kinds, it is not limited to such use. It is also possible to make bags from the material to tsex. store heat-sensitive objects, such as e.g. portable radios, explosive cartridges, etc. ”but the material is also useful for covering surfaces, sleeping bags, tent bases and the like in connection with the manufacture and equipment of scaffolding, which are to be used to provide protection against nuclear thermal flashes.

Såsom eldsäkert bindemedel för att klistra de här nämnda glaspärlorna på det reflekterande skiktet mot det yttre skiktets vända yta användes företrädesvis ett plastbindemedel, som framställes genom polyaddition av triisocyanater med två- värda alkoholer eller andra hydroxylgrupphaltiga föreningar.As the refractory binder for adhering the glass beads mentioned here on the reflective layer to the facing surface of the outer layer, a plastic binder is preferably used which is prepared by polyaddition of triisocyanates with dihydric alcohols or other hydroxyl group-containing compounds.

Det härvid erhållna polyuretanet löses i en keton och tillsättes i förhållandet 9:1 med någon lämplig, i handeln tillgänglig, mättad bromlösning. Vid omröring under 6 timmar under luftuteslutning tillsättes långsamt 5 g magnesiumpulver (torrvikt) per 100 g polyuretan (våtvikt). Av detta plastbin- demedel påföres sedan en kvantitet av ca. 25 g/m2 på det ref- lekterande skiktet resp. den motsvarande banan av textilvävnad och frigöres i anslutning härtill från lösningsmedelsångorna i en luftström vid en temperatur av ca. l80°C. I samband härmed strös glaspärlorna över den med bindemedlet försedda ytan av materialbanan. För att likformigt fördela glaspärlorna över materialbanans yta'skakas banan i riktningen för dess plan.The polyurethane thus obtained is dissolved in a ketone and added in a ratio of 9: 1 with any suitable commercially available saturated bromine solution. When stirring for 6 hours under air exclusion, slowly add 5 g of magnesium powder (dry weight) per 100 g of polyurethane (wet weight). A quantity of approx. 25 g / m2 on the reflective layer resp. the corresponding web of textile fabric and is subsequently released from the solvent vapors in an air stream at a temperature of approx. 180 ° C. In connection with this, the glass beads are sprinkled over the surface of the material web provided with the binder. In order to evenly distribute the glass beads over the surface of the web of material, the web is shaken in the direction of its plane.
