UV resin, lub npe hu ua photosensitive resin, yog oligomer uas tuaj yeem hloov pauv lub cev thiab tshuaj lom neeg hauv lub sijhawm luv luv tom qab raug rau lub teeb, thiab tom qab ntawd crosslink thiab solidify.UV resin feem ntau muab faib ua hnyav raws li UV resin thiab dej-raws li UV resin.
Cov kuab tshuaj raws li UV resin
Cov kuab tshuaj raws li UV resins feem ntau suav nrog: UV unsaturated polyester, UV epoxy acrylate, UV polyurethane acrylate, UV polyester acrylate, UV polyether acrylate, UV ntshiab acrylic resin, UV epoxy resin, UV silicone oligomer, thiab lwm yam.
UV resin dej
Waterborne UV resin yog hais txog UV resin uas yog soluble hauv dej lossis tuaj yeem tawg nrog dej.Cov molecule muaj qee cov pawg muaj zog hydrophilic, xws li carboxyl, hydroxyl, amino, ether, thiab acylamine pawg;Nws kuj muaj cov pab pawg tsis txaus, xws li acryloyl, methacryloyl lossis allyl pawg.Waterborne UV ntoo tuaj yeem muab faib ua peb pawg: tshuaj pleev, dej dispersible thiab dej-soluble, feem ntau suav nrog peb pawg: waterborne polyurethane acrylate, waterborne epoxy acrylate thiab waterborne polyester acrylate.
Cov dej uas muaj UV resin feem ntau muaj 80-90% dej thiab 10-20% lwm yam khoom ntxiv.Tom qab txheej txheej thiab polishing, nyias txheej txheej ntawm polymer yog sab laug rau saum npoo ntawm substrate, uas ua rau cov txheej txheem sib txawv vim muaj cov qauv sib txawv.Xws li siab gloss, matt, abrasion resistant, thiab lwm yam.
Waterborne resin yog lub ntsiab ntawm Z nyob rau hauv waterborne UV resin.Nws txiav txim siab thiab cuam tshuam cov khoom ntawm cov dej uas muaj UV resin, xws li luster, adhesion, abrasion resistance, dryness, thiab lwm yam. Yog li ntawd, kev xaiv kom zoo ntawm cov dej uas muaj UV resin yog tus yuam sij rau kev ua tiav ntawm kev xa dej ntawm UV resin.
Muaj ntau ntau hom resins, xws li waterborne rosin modified maleic resin, waterborne polyurethane resin, waterborne acrylic resin, waterborne alkyd resin, waterborne amino resin, thiab lwm yam. Rau waterborne UV resin, cov resin xaiv yuav tsum muaj cov yam ntxwv ntawm yooj yim soluble ntsev, zoo. dej tso tawm, zoo gloss tom qab tsim zaj duab xis, tshav kub tsis kam, tshuaj tiv thaiv, ceev ceev kom qhuav, thiab lwm yam, thaum waterborne acrylic copolymer resin tuaj yeem ua tau raws li qhov yuav tsum tau luam ntawv thiab glazing mus rau qhov loj.Yog li ntawd, thaum npaj waterborne UV resin, waterborne acrylic copolymer system yog peb xaiv zoo tshaj plaws.
Aqueous acrylic copolymer resin tuaj yeem muab faib ua aqueous acrylic resin tov, aqueous acrylic dispersion, thiab acrylic lotion.Acrylic lotion tuaj yeem muab faib ua zaj duab xis-tsim acrylic lotion thiab non film-forming acrylic lotion.Cov khoom ntawm waterborne acrylic copolymer resin yog tsim los ntawm monomers.Kev ua tau zoo thiab txheej txheem synthesis.Qee cov monomers tuaj yeem txhim kho luster thiab hardness, thaum lwm tus tuaj yeem muab tshuaj tiv thaiv thiab adhesion.Ntau qhov kev sim tau ua pov thawj tias cov dej ua los ntawm UV resin, uas yog kev tshawb fawb sib xyaw nrog aqueous acrylic acid tov thiab acrylic acid lotion, muaj cov khoom zoo tagnrho.
