Uvod
Pronalazak se odnosi na trake za brtvljenje u području građevinarstva, osobito za brtvljenje prijelaza između tijela i elemenata gradnje, sastojeći se od jednog nosećeg sloja i snažno samoljepivog sloja za lijepljenje, koji imade žljebove.
Stanje tehnike
Kod podizanja zgrada građevinski se elementi, kao na pr. prozori, vrata, svjetlosne kupole, dimnjaci i fasade, koji se sastoje od najrazličitijih materijala, spajaju s tijelom gradnje. Kako različiti materijali imaju različite za materijal specifične koeficijente toplinskog istezanja, potrebno je da se između različitih građevinskih elemenata predvide razmaci za istezanje. Ovi, nazvani također istezišta , prekidi zaštitnog vanjskog sloja zgrade moraju se posebno brtviti.
Iz stanja tehnike poznati su različiti postupci, da bi se postiglo takvo brtvljenje. U upotrebi su tzv. montažne pjene, obično na bazi poliuretana, s kojima se ta istezišta mogu popuniti pjenom. Ovaj je postupak lak i brzo izvodiv, ali pjene imaju nedostatak, da kroz nastale pore prodire vlaga i time ne postoji više izolaciono djelovanje.
Daljnja metoda brtvljenja prijelaznih prekida koriste se elastične mase za oblikovanje. Time je isključeno prodiranje vlage izvana, ali se istovremeno sprječava svaka cirkulacija zraka, čime u zidu može doći do pljesni ali i oštećenja od mraza.
Pored toga poznate su i metode, kod kojih se najprije ubacuje ljepilo u pukotine, a zatim za dobro zatvaranje stavlja se brtvena traka koja spaja dijelove. Za to su međutim potrebne dvije radne operacije, a osobito stavljanje ljepila pod datim radnim uslovima često ne uspijeva na zadovoljavajući način. Općenito se potroše ekstremne količine ljepila, a istovremeno sprječava ovaj način brtvljenja izjednačenje pritiska pare između unutarnjeg prostora rastojanja i okoline, zbog čega može na primjer doći do stvaranja plijesni.
Osim učvršćivanja traka za brtvljenje pomoću ljepila može se koristiti mehaničko učvršćivanje. Za to se traka za brtvljenje na pr. zavrtnjima, stezaljkama ili stiskanjem. Izjednačenje pritiska pare je kod takvih brtvljenja osigurano, ali je postavljanje dugotrajno i kako su probijene trake za brtvljenje, mora se ponovno brtviti.
Specijalni oblik, način,brtvljenja realizira se profilima iz lima. Ovi imaju prednost kod prijelaza vrata na pr. na terasama. Ovaj oblik brtvljenja je veoma skup i zahtjeva mnogo vremena. Koristi se i tamo, gdje dolazi do dodira s bitumenom, i radi toga je primjena materijala koji ne podnose bitumen,kao što su često korištene trake iz PVC-P-NB, nemoguća.
Kompleksni zadatak predstojećeg pronalaska bio je dakle, staviti na raspolaganje trake za brtvljenje, koje se mogu lako i brzo postaviti, koje omogućavaju prijelaz među što je moguće više različitih materijala, a istovremeno daju dobro brtvljenje i omogućavaju izjednačenje pritiska pare.
Opis pronalaska
Predmet izuma su dakle trake za brtvljenje u građevinarstvu, osobito za brtvljenje prijelaza između građevinskih tijela i elemenata gradnje, sastojeći se od nosećeg sloja i viasokosamoljepivog sloja za lijepljenje, koji imade žljebove.
Na iznenađenje je otkriveno, da traka za brtvljenje ovog pronalaska omogućavaju dobre brtvljenje a istovremeno žljebovi omogućavaju izjednačenje pritiska pare.
Kako su brtve za te svrhe već kod proizvodnje opremljene ljepljivim slojem, otpada dodatni rad prije radilišta i postiže se jednakomjernija raspodjela ljepljivog sloja.
Noseći sloj
Noseći slojevi koji se prema pronalasku trebaju umetnuti izrađeni su od materijala koji su prema stanju tehnike, poznati za krovne trake, kao na pr. klorsulfonirani polietilen (CSM), etilenkopelimerizet-bitumen (ECB), etilen-propilen, terpolimer-kaučuk (EPDM), etilen-vinilacetat-terpolimer (EVA), legure iz fleksibilnih poliolefina (FPO), klorirani polietilen (Pe-C),poliizobutilen (P1B), polivinilklorid meki (PVC-P) Osobita se prednost daje nosećim slojevima na bazi mekog polivinilklorida, koji se pomoću postupka za bubrenje i vrućim zavarivanjem bez problema mogu spajati s uobičajenim krovnim trakama iz mekog PVC-a i time omogućavaju nepropusne prijelaze. Takvi se noseći slojevi posebice koriste, one koje su otporne na bitumen, postojane, pri čemu se prvenstveno primjenjuje polimeromekšani PVC (PVC-p). Navedeni materijali mogu za poboljšanje upotrebnih svojstava biti modificirani pomoću uobičajenih aditiva /TASCHENBUCH DER KUNSTSTOFFADDITIVE VON GRCHTER/MULLER, 2. naklada, CARL HANSER VERLAG MUNCHEN WIEN, 2983 /
Debljina nosećeg sloja iznosi prvenstveno 0,8 do , osobito od 1 do .
Ljepljivi sloj
Za ljepivi sloj primjenjivo ljepilo - prema izumu - odlikuje se time, da je visoko samoljepiv. Pod snagom lijepljenje treba podrazumijevati onu silu, koja je potrebna da se određeni ljepivi sloj odvaja od definirane podloge. Sile ljepivosti izračunavaju se empirički i za građevinarstvo su ovako klasificirani:

Pod visokosamoljepivim ljepilom u smislu predstojećeg pronalaska podrazumijeva se ljepilo snage ljepljenja od najmanje lo N (cm. Prednost se daje ljepilima snage lijepljenja od 10 do 20 N/cm kod upotrebe. Prema pronalasku pogodna su sva ljepila poznata u tehnici kao samoljepiva ljepila.Pod time se osobito podrazumijevaju fenolne smole (bakeliti), Bituminas, SBS, a osobito su pogodna ljepila iz modificiranog kaučuka, kao na pr. etilen-propilen-terpolimer-kaučuk (EPDM), stirol-butadien-kaučuk (SBR), akrilnitril-butadien-kaučuk (NBR) a osobito butilkaučuk (IIR). Ljepila se mogu koristiti pojedinačno, ali i u kombinacijama. Dodatno mogu ljepila dobiti još i uobičajene, iz tehnike poznate aditive (TASCHENBUCH DER KUNSTSTOFFADDITIVE VON GRCHTER/MULLER, 2. izdanje, CARL HANSER VERLAG MUNCHEN WIEN, 1983).
Prema pronalasku je ljepivi sloj u smjeru toka tračne geometrije, što znači da se stvaraju žljebovi odn. brazde. Cjelokupna debljina ljepivog sloja iznosi prvenstveno 0,l do posebno 0,3 do . Žljebovi mogu u proizvodnom smjeru ili u kutu od 10 do 80°, prvenstveno 25 do 75° prema proizvodnom smjeru teći. Mogu se na pr. žljebovi u proizvodnom smjeru nadograditi takvima s katom između 10 i 80°.
Širina ljepivih traka iznosi prvenstveno 10 do 30, osobito poželjno 15 do , odgovarajući ljepivi žljebovi pokazuju prvenstveno širinu od 2 do 10, posebice 5 do . Razlika u visini između žljeba i kobilice iznositi 0,1 do 2,9, posebice 0,3 do
