Description

Selvklebende folieSelf-adhesive foil

Foreliggende oppfinnelse vedrører en selvklebende folie, særlig en aluminiumfolie, og har til oppgave å utforme folien med hensyn på det selvklebende klister, på en slik måte at det oppnås særlig stor flammesikkerhet uten betydelig reduksjon av de vanlige selvklebende egenskaper. The present invention relates to a self-adhesive foil, in particular an aluminum foil, and has the task of designing the foil with regard to the self-adhesive adhesive, in such a way that particularly high flame safety is achieved without a significant reduction of the usual self-adhesive properties.

Ifølge oppfinnelsen oppnås dette ved at det selvklebende klister består av en blanding av en poly-Z-^hålogenbutadien og en halogenert parafin. According to the invention, this is achieved by the self-adhesive adhesive consisting of a mixture of a poly-Z-halogenbutadiene and a halogenated paraffin.

En fordelaktig løsning av problemet består ifølge oppfinnelsen i at blandingen tilsettes stoffer som reduserer antenneligheten, for eksempel bariummetab.ørat, trif enylfosfat, br omerte difenyler eller difenyleter eller antimontrioksyd. According to the invention, an advantageous solution to the problem consists in adding to the mixture substances which reduce the flammability, for example barium metaborate, triphenyl phosphate, brominated diphenyls or diphenyl ether or antimony trioxide.

Videre er det ifølge oppfinnelsen en foredel at de stoffer som tilsettes blandingen har evne til å avspalte vann ved oppvarming, for eksempel aluminiumsilikater. Furthermore, according to the invention, it is an advantage that the substances that are added to the mixture have the ability to separate water when heated, for example aluminum silicates.

Ifølge oppfinnelsen frembringes en selvklebende folie, særlig en aluminiumfolie, som er meget vanskelig å anvende, mens det på den andre siden har tilfredsstillende selvklebende egenskaper. Dette gjelder særlig de hovedområder for bruken av ? folier utformet i overensstemmelse med oppfinnelsen, for eksempel for bygnings isolering. For eksempel kan fugene til lamellmatter av typen aluminiumdekkete glasullmatter tilklistres ved isola-sjonsarbeider, særlig isolering av rørledninger. Selvkleberens avtrekkings-og skjiærstyrke er tilstrekkelig for slike færmål. Selvklebingsevnen forblir uforandret i en årrekke. Antenneligheten er derimot så lav at forskriftene ifølge den tilsvarende DIN-norm 4102 oppfylles helt. Klisteret i en slik folie kan heller ikke føre glødeild videre, for eksempel langs en isolerjt rørledning fra en etasje til en annen. According to the invention, a self-adhesive foil, in particular an aluminum foil, is produced, which is very difficult to use, while on the other hand it has satisfactory self-adhesive properties. This particularly applies to the main areas for the use of ? foils designed in accordance with the invention, for example for building insulation. For example, the joints of lamellar mats of the type aluminium-covered glass wool mats can be glued during insulation work, in particular the insulation of pipelines. The adhesive's pull-off and shear strength is sufficient for such fair targets. The self-adhesive ability remains unchanged for a number of years. The flammability, on the other hand, is so low that the regulations according to the corresponding DIN standard 4102 are fully met. The adhesive in such a foil cannot also lead a glow plug further, for example along an insulated pipeline from one floor to another.

Det er i og for seg kjent å fremstille en kontaktlim av folie-2-klorbutadiener ved tilsetning av harpikser, fyllmidler osv., idet denne limen etter lenger eller kortere åpen tid binder og herdner, hvoretter limen ikke lenger har noen selvklebende egenskaper. Det har imidlertid overraskende vist seg, at man av en blanding av poly-2-klorbutadien med halogenerte parafiner og/ eller lignende halogenerte stoffer oppnår et klister, som har både selvklebende egenskaper og beholder disse i en årrekke. It is known per se to produce a contact adhesive from foil-2-chlorobutadienes by adding resins, fillers, etc., as this adhesive binds and hardens after a longer or shorter open time, after which the adhesive no longer has any self-adhesive properties. However, it has surprisingly been shown that a mixture of poly-2-chlorobutadiene with halogenated paraffins and/or similar halogenated substances produces an adhesive which has both self-adhesive properties and retains these for a number of years.

Til blandingen kan det evnetuelt tilsettes et tilsetningsstoff av kjente harpikser, såsom kolofonium, kolofoniumestre, poly-terpenharpikser, terpenfenolharpikser, fenolharpikser osv. An additive of known resins can optionally be added to the mixture, such as rosin, rosin esters, polyterpene resins, terpenephenol resins, phenolic resins, etc.

Man kan for å variere klisteregenskapene og eventuelt for å redusere antennelighet tilsette fyllmidler, såsom for eksempel sihkoksyd og titandioksyd, kritt eller også borholdige fosfat-eller halogenholdige uorganiske stoffer, såsom boriummetaborat, trifenylfosfat, bromerte difenyler eller difenyleter m. fl. eller antimontrioksyd. Videre kan man tilsette silikater, blant annet aluminiumsilikat og andre stoffer som har den egenskap, In order to vary the adhesive properties and possibly to reduce flammability, fillers can be added, such as, for example, silica and titanium dioxide, chalk or also boron-containing phosphate or halogen-containing inorganic substances, such as boron metaborate, triphenyl phosphate, brominated diphenyls or diphenyl ether, etc. or antimony trioxide. You can also add silicates, including aluminum silicate and other substances that have the property,

ved<r->at<r->

at de/oppvarming avspalter vann og som derved reduserer antenneligheten. that de/heating splits off water and thereby reduces flammability.

Selvsagt kan det også tilsettes andre polymerer, såsom kautschuk, klorkautschuk, akrylater, styrenbutadien, styren-isopren osv. Of course, other polymers can also be added, such as rubber, chlorinated rubber, acrylates, styrene-butadiene, styrene-isoprene, etc.

Eksempel 1Example 1

.Man bløtla 265 g'*Bayprenn og 40 g "Alresen PA 101" i 900 g toluen, tilsatte 30 g titandioksyd, 10 g magnesiumoksyd og 10 g sinkoksyd og rørte til man fikk en homogen masse. Deretter tilsatte man 493 g klorparafin (omtrent 701 klor) og justerte ved ytterligere tilsetning av løsningsmiddel løsningens viskositet til 15 ' 000 m Pa-, s. 265 g of Bayprenn and 40 g of "Alresen PA 101" were soaked in 900 g of toluene, 30 g of titanium dioxide, 10 g of magnesium oxide and 10 g of zinc oxide were added and stirred until a homogeneous mass was obtained. 493 g of chlorinated paraffin (approximately 701 chlorine) were then added and, by further addition of solvent, the viscosity of the solution was adjusted to 15,000 m Pa-, s.

Den utstrukne og tørkete filmen (25g/m ) hadde en avtrekkings-styrke på 6 til 7 N/CM og en skjærstyrke på en 5 x 5 cm stor etikett på 8 timer ved en belastning på 2 kg. The stretched and dried film (25g/m ) had a pull-off strength of 6 to 7 N/CM and a shear strength of a 5 x 5 cm label in 8 hours at a load of 2 kg.

Eksempel 2Example 2

300 g poly-2-klorbutadién. og 30 g polyterpenharpiks med et smeltepunkt på ca. 115°C ble bløtlagt i 900 g toluen, 30 g "Bromkal 70-5 DE" (en bromert difenyleterblanding) og 400 g klorparafin ble tilsatt og det ble rørt om til en ensartet masse var oppnådd. Ved utspeing med toluen ble viskositeten justert til ca. 15 000 m jPa. s og den tørkete filmen fikk lignende ver-dier som i eksempel 1. 300 g of poly-2-chlorobutadiene. and 30 g of polyterpene resin with a melting point of approx. 115°C was soaked in 900 g of toluene, 30 g of "Bromkal 70-5 DE" (a brominated diphenyl ether mixture) and 400 g of chloroparaffin were added and it was stirred until a uniform mass was obtained. By diluting with toluene, the viscosity was adjusted to approx. 15,000 m jPa. s and the dried film obtained similar values as in example 1.

En selvklebende folie ifølge oppfinnelsen er vist som er eksempel i tegningen. An adhesive foil according to the invention is shown as an example in the drawing.

Aluminiumfolien 1 har på sin ene side det selvklebende sjiktet 2, som består av en blanding av en poly-2-halogenbutadien og klorparafin. Blandingsforholdet kan avhengig av fordringene på den ene siden til de selvklebende egenskaper og på den andre siden til flammesikkerheten, bevege seg innenfor et område av 20 til 70% poly-2-halogenbutadien og 30 til 80% klorparafin. Under det selvklebende sjiktet 2 finnes det et beskyttelsessjikt 3 som ved fremstilling eller utforming er tilpasset til en så mye svakere klebeevne mot det selvklebende sjiktet, at det kan trekkes av. The aluminum foil 1 has on one side the self-adhesive layer 2, which consists of a mixture of a poly-2-halobutadiene and chlorinated paraffin. Depending on the requirements on the one hand for the self-adhesive properties and on the other for the flame safety, the mixing ratio can range from 20 to 70% poly-2-halogenbutadiene and 30 to 80% chlorinated paraffin. Beneath the self-adhesive layer 2 there is a protective layer 3 which, by manufacture or design, is adapted to such a much weaker adhesive ability to the self-adhesive layer that it can be pulled off.

Også andre halogenerte forbindelser som er likeverdige med hensyn til antenneligheten, kan velges helt eller delvis i stedet for de halogenerte parafinene, for eksempel klorerte polyalkener eller klorerte estre. Ved tilsetning av ytterligere stoffer som senker antenneligheten, for eksempel antimontrioksyd, kan flammesikkerheten, ifølge de iakttagelser som er gjort, særlig glødesikkerheten, økes videre uten betydelig reduksjon av de selvklebende egenskaper. Det samme gjelder ved tilsetning av motsvarende stoffer som avspalter vann ved oppvarming, for eksempel aluminiumsilikat. Dermed blir til og med flammesikkerheten til foliematerialet "forbedret. Also, other halogenated compounds which are equivalent in terms of flammability can be chosen in whole or in part instead of the halogenated paraffins, for example chlorinated polyalkenes or chlorinated esters. By adding further substances that lower the flammability, for example antimony trioxide, the flame safety, according to the observations that have been made, especially the glow safety, can be further increased without a significant reduction of the self-adhesive properties. The same applies to the addition of corresponding substances that release water when heated, for example aluminum silicate. Thus, even the flame safety of the foil material is "improved.
