Epoxy acrylate resin, tseem hu ua vinyl ester resin, yog hloov kho epoxy resin uas yaj hauv styrene tom qab cov tshuaj tiv thaiv ntawm epoxy resin thiab acrylic acid;Epoxy acrylate resin muaj cov yam ntxwv zoo ntawm epoxy resin, tab sis nws cov khoom kho thiab molding zoo dua.Nws tsis yog cumbersome li epoxy resin.Nws yog ib lub tshav kub curing resin.Nws muaj cov dej tsis zoo, dej kub tsis kam, tshuaj tiv thaiv, adhesion thiab toughness.Nws tuaj yeem kho tau los ntawm cov organic peroxide curing txoj kev (tsawg kub kub) los yog lub teeb curing txoj kev, thiab yog dav siv nyob rau hauv cov nram qab no teb: corrosion resistant FRP khoom, xws li FRP tso tsheb hlau luam, kav dej, yees thiab corrosion resistant daim phiaj;Kev tiv thaiv corrosion ua haujlwm, xws li cov cement raws lossis hlau raws li iav fiber reinforced yas hauv ob sab phlu, siab corrosion resistant pem teb;Lub zog siab FRP, xws li pultruded FRP profiles, cov khoom ua si, FRP nkoj, thiab lwm yam;Heavy anti-corrosion iav flake txheej;Lwm yam xws li UV number case, hnyav anti-corrosion industrial pem teb, thiab lwm yam.
Lub synthesis ntawm epoxy acrylate tau patented nyob rau hauv lub 1950s, tab sis nws tsis tau siv rau lub tshav pob ntawm UV kho kom txog rau thaum 1970s.Epoxy acrylate yog tsim los ntawm kev lag luam epoxy resin thiab acrylic acid los yog methacrylate, uas yog ib yam ntawm UV curing oligomer nrog loj noj nyob rau hauv domestic UV curing kev lag luam tam sim no;Raws li hom qauv, epoxy acrylate tuaj yeem muab faib ua bisphenol A epoxy acrylate, phenolic epoxy acrylate, hloov epoxy acrylate thiab epoxidized roj acrylate.
Cov qauv molecular ntawm bisphenol A epoxy acrylate muaj cov nplhaib uas muaj ntxhiab thiab sab hydroxyl pawg, uas yog qhov zoo rau kev txhim kho adhesion, thaum lub adhesion ntawm aliphatic epoxy acrylate tsis zoo;Lub nplhaib aromatic qauv kuj endows cov resin nrog siab rigidity, tensile zog thiab thermal stability.
Epoxy acrylate yog siv dav siv UV curable prepolymer.Raws li cov qauv, nws tuaj yeem muab faib ua bisphenol A epoxy acrylate, phenolic epoxy acrylate, epoxidized roj acrylate thiab hloov kho epoxy acrylate.Raws li lub ntsiab resin, kho epoxy acrylate zaj duab xis tau zoo adhesion, tshuaj tiv thaiv thiab lub zog, tab sis kuj tseem muaj qhov tsis zoo, xws li tsis txaus saj thiab siab brittleness ntawm cov yeeb yaj kiab kho.Yog li ntawd, txhawm rau ua kom tau raws li qhov xav tau ntawm cov teb sib txawv, kev hloov kho (lub cev thiab / lossis tshuaj lom neeg) ntawm epoxy acrylate tau dhau los ua ib qho ntawm cov kev tshawb fawb tsom rau hauv daim teb no.
Lub flammability ntawm epoxy acrylate txwv nws daim ntawv thov nyob rau hauv microelectronics thiab lwm yam teb.Rau cov organic coatings, nplaim retardancy kuj tseem ceeb heev.Ntxiv phosphorus compounds tuaj yeem txhim kho cov nplaim hluav taws.Thaum cov txheej txheej ntawm cov polymer kub hnyiab, cov phosphorus uas muaj cov khoom sib txuas yuav nthuav dav thiab qhov ntim yuav nce ntxiv, thiab sab hauv ntawm cov polymer yuav tsis pub dawb los ntawm cov nplaim taws, yog li txhim kho cov nplaim hluav taws.
