Cov kws tshawb nrhiav pom tias kev hloov kho ntawm epoxy acrylate (EA) nrog cov carboxyl-terminated intermediate ua rau cov zaj duab xis yooj ywm dua thiab txo qhov viscosity ntawm cov resin. Txoj kev tshawb fawb kuj ua pov thawj tias cov khoom siv raw siv pheej yig thiab yooj yim nrhiav tau.
Epoxy acrylate (EA) tam sim no yog cov oligomer uas siv tau ntau tshaj plaws hauv UV-curable vim nws lub sijhawm kho luv luv, lub zog tawv ntawm txheej, cov khoom siv kho tshuab zoo heev, thiab kev ruaj khov thermal. Txhawm rau daws cov teeb meem ntawm kev tawg yooj yim, kev ywj pheej tsis zoo, thiab viscosity siab ntawm EA, cov epoxy acrylate oligomer uas muaj viscosity qis thiab kev ywj pheej siab ntawm UV-curable tau npaj thiab siv rau cov txheej txheem UV-curable. Cov carboxyl terminated intermediate tau los ntawm kev sib xyaw ntawm anhydride thiab diol tau siv los hloov kho EA kom txhim kho qhov yooj ywm ntawm cov zaj duab xis kho, thiab qhov yooj ywm tau kho los ntawm qhov ntev ntawm cov saw hlau carbon ntawm diols.
Vim lawv cov khoom zoo tshaj plaws, cov epoxy resins siv dav dua hauv kev lag luam txheej dua li lwm cov chav kawm ntawm cov binder. Hauv lawv phau ntawv siv tshiab "Epoxy Resins", cov kws sau ntawv Dornbusch, Christ thiab Rasing piav qhia txog cov hauv paus ntawm cov tshuaj lom neeg ntawm pawg epoxy thiab siv cov qauv tshwj xeeb los piav qhia txog kev siv epoxy thiab phenoxy resins hauv kev lag luam txheej - suav nrog kev tiv thaiv xeb, txheej hauv pem teb, txheej hmoov thiab txheej sab hauv.
Cov resin viscosity tau txo qis los ntawm kev hloov E51 ib nrab nrog binary glycidyl ether. Piv nrog rau EA tsis hloov kho, qhov viscosity ntawm cov resin npaj hauv txoj kev tshawb fawb no txo qis los ntawm 29800 mus rau 13920 mPa s (25 ° C), thiab qhov yooj ywm ntawm cov zaj duab xis kho tau nce ntxiv los ntawm 12 mus rau 1 hli. Piv nrog rau EA hloov kho uas muaj nyob hauv khw, cov khoom siv raw siv hauv txoj kev tshawb fawb no yog tus nqi qis thiab yooj yim kom tau txais nrog qhov kub ntawm cov tshuaj tiv thaiv hauv qab 130 ° C, siv cov txheej txheem yooj yim, thiab tsis muaj cov kuab tshuaj organic.
Cov kev tshawb fawb no tau luam tawm hauv Journal of Coatings Technology and Research, Volume 21, thaum lub Kaum Ib Hlis 2023.
