Cov kws tshawb fawb pom tau tias kev hloov kho ntawm epoxy acrylate (EA) nrog cov carboxyl-terminated intermediate tsub kom qhov yooj ntawm cov zaj duab xis thiab txo cov viscosity ntawm cov resin. Txoj kev tshawb no tseem ua pov thawj tias cov khoom siv raw siv yog pheej yig thiab yooj yim muaj.
Epoxy acrylate (EA) yog tam sim no siv ntau tshaj UV-kho tau oligomer vim nws lub sij hawm luv luv, txheej txheej hardness, zoo heev txhua yam khoom, thiab thermal stability. Txhawm rau daws cov teeb meem ntawm qhov siab brittleness, tsis yooj yim, thiab siab viscosity ntawm EA, UV-kho tau epoxy acrylate oligomer nrog tsawg viscosity thiab siab yooj tau npaj thiab siv rau UV-kho coatings. Carboxyl terminated intermediate tau los ntawm cov tshuaj tiv thaiv ntawm anhydride thiab diol yog siv los hloov EA los txhim kho qhov yooj yim ntawm cov yeeb yaj kiab kho, thiab qhov hloov pauv tau hloov kho los ntawm qhov ntev ntawm cov pa roj carbon diols.
Vim lawv cov khoom zoo heev, epoxy resins tau siv dav hauv kev lag luam txheej ntau dua li yuav luag txhua chav kawm ntawm cov ntawv khi. Hauv lawv phau ntawv siv tshiab "Epoxy Resins", cov kws sau ntawv Dornbusch, Christ thiab Rasing piav qhia txog cov ntsiab lus ntawm chemistry ntawm pawg epoxy thiab siv cov qauv tshwj xeeb los piav qhia txog kev siv epoxy thiab phenoxy resins hauv cov txheej txheem - suav nrog kev tiv thaiv corrosion, txheej hauv pem teb, hmoov txheej thiab sab hauv tuaj yeem coatings.
Cov viscosity resin raug txo los ntawm ib nrab hloov E51 nrog binary glycidyl ether. Piv nrog EA tsis hloov kho, qhov viscosity ntawm cov resin npaj rau hauv txoj kev tshawb no txo qis los ntawm 29800 mus rau 13920 mPa s (25 ° C), thiab qhov hloov tau ntawm cov yeeb yaj kiab kho tau nce ntawm 12 mus rau 1 hli. Piv nrog rau cov khoom lag luam hloov kho EA, cov khoom siv raw siv hauv txoj kev tshawb no yog tus nqi qis thiab yooj yim kom tau txais nrog cov tshuaj tiv thaiv kub qis dua 130 ° C, siv cov txheej txheem synthesis yooj yim, thiab tsis muaj cov kuab tshuaj organic.
Qhov kev tshawb fawb no tau luam tawm nyob rau hauv Journal of Coatings Technology and Research, Volume 21, in November 2023.
