Kakovost poliuretanskega lepilnega spoja med lesom in jeklom : diplomsko delo = The quality of the polyurethane adhesive bond between wood and steel : B. Sc. thesis

Škamlec, Marko

Lepljeni lamelirani nosilci se uporabljajo v konstrukcijske namene. Potrebno jih je spajati z jeklenimi deli. Vijačenje jeklenih delov lahko zamenjamo z lepljenjem in tako povečamo togost spoja. V ... raziskavi smo proučevali kakovost poliuretanskega lepilnega spoja med lesom in jeklom. Uporabili smo tri različna enokomponentna poliuretanska lepila: COSMO PU-100.110, COSMO PU-180.150 in COSMO PU- 190.110. Lesene lamele smo izdelali iz smrekovine in jih zlepili z jeklenimi lamelami. Preizkušance smo za 6 dni izpostavili trem različnim pogojem in sicer: standardni klimi, vlažni klimi ter namakanju v vodi. Izvedli smo test natezno strižne trdnosti spojev s preklopom po standardu SIST EN 205:2003 in določili delež loma po lesu. Kakovost lepilnega spoja med lesom in jeklom je bila odvisna od uporabljenega poliuretanskega lepila. Najboljše se je izkazalo lepilo COSMO PU-190.110, ki je po izpostavitvi standardni klimi doseglo strižno trdnost 8,49 N/mm2 in 53 % delež loma po lesu. Na kakovost lepilnega spoja je prav tako vplivala priprava preizkušancev pred testiranjem. Najboljše so se odrezali preizkušanci izpostavljeni standardni klimi in najslabše preizkušanci namočeni v vodo. Lepili COSMO PU-190.110 in COSMO PU-180.150 sta se izkazali kot uporabni za lepljenje jekla in lesa v suhih pogojih (standardna klima). Lepilo COSMO PU- 100.110 se je izkazalo kot neuporabno za lepljenje jekla in lesa v proučevanih pogojih.
