Epoxy acrylate resin, yomwe imadziwikanso kuti vinyl ester resin, ndi utomoni wosinthidwa wa epoxy womwe umasungunuka mu styrene pambuyo pa zomwe epoxy resin ndi acrylic acid;Utoto wa epoxy acrylate uli ndi mawonekedwe abwino kwambiri a epoxy resin, koma machiritso ake ndi mawonekedwe ake ndiabwinoko.Sizovuta monga epoxy resin.Ndi utomoni wochiritsa kutentha.Ili ndi kukana madzi abwino kwambiri, kukana madzi otentha, kukana mankhwala, kumamatira komanso kulimba.Itha kuchiritsidwa ndi njira yochiritsira ya organic peroxide (kutentha kotsika kwambiri) kapena njira yochiritsira yopepuka, ndipo imagwiritsidwa ntchito kwambiri m'magawo otsatirawa: zinthu zosagwirizana ndi dzimbiri za FRP, monga akasinja a FRP, mapaipi, nsanja ndi ma grids osagwirizana ndi dzimbiri;Anti dzimbiri ntchito, monga simenti zochokera kapena chitsulo zochokera galasi CHIKWANGWANI analimbitsa pulasitiki akalowa, mkulu dzimbiri zosagwira pansi;FRP yamphamvu kwambiri, monga mbiri ya FRP, zinthu zamasewera, mabwato a FRP, ndi zina zambiri;Chophimba cholimba cha anti-corrosion glass flake;Ena monga UV inki, katundu odana ndi dzimbiri pansi mafakitale, etc.
Kuphatikizika kwa epoxy acrylate kunali kovomerezeka m'zaka za m'ma 1950, koma sikunagwiritsidwe ntchito kumunda wa machiritso a UV mpaka 1970s.Epoxy acrylate amapangidwa kuchokera ku malonda epoxy resin ndi acrylic acid kapena methacrylate, yomwe ndi mtundu wa oligomer yochiritsa UV yomwe imagwiritsidwa ntchito kwambiri m'makampani ochiritsa a UV pakali pano;Malinga ndi mtundu wa kamangidwe, epoxy acrylate akhoza kugawidwa mu bisphenol A epoxy acrylate, phenolic epoxy acrylate, modified epoxy acrylate ndi epoxidized mafuta acrylate.
Mapangidwe a maselo a bisphenol A epoxy acrylate amakhala ndi mphete yonunkhira komanso gulu la hydroxyl, lomwe limathandizira kuwongolera kumamatira, pomwe kumatira kwa aliphatic epoxy acrylate ndikosavuta;Mapangidwe a mphete onunkhira amathandizanso kuti utomoni ukhale wokhazikika kwambiri, kulimba kwamphamvu komanso kukhazikika kwamafuta.
Epoxy acrylate ndi yogwiritsidwa ntchito kwambiri ndi UV prepolymer.Potengera kapangidwe kake, imatha kugawidwa kukhala bisphenol A epoxy acrylate, phenolic epoxy acrylate, epoxidized mafuta acrylate ndi epoxy acrylate yosinthidwa.Monga utomoni waukulu, filimu yochiritsidwa ya epoxy acrylate imakhala ndi zomatira zabwino, kukana mankhwala ndi mphamvu, koma palinso zofooka, monga kusinthasintha kosakwanira komanso kuphulika kwakukulu kwa filimu yochiritsidwa.Choncho, pofuna kukwaniritsa zosowa za madera osiyanasiyana, kusintha (kwakuthupi ndi / kapena mankhwala) kwa epoxy acrylate kwakhala chimodzi mwazofukufuku zomwe zikuyang'ana pa ntchitoyi.
Kutentha kwa epoxy acrylate kumalepheretsa kugwiritsidwa ntchito kwake mu microelectronics ndi zina.Kwa zokutira organic, kuchedwa kwa lawi ndikofunikira kwambiri.Kuphatikizika kwa phosphorous kumathandizira kuchepetsa kutentha kwa moto.Pamene pamwamba wosanjikiza wa polima amayaka, phosphorous munali pawiri adzakula ndipo voliyumu adzawonjezeka, ndipo mkati mwa polima adzakhala wopanda kuwotcha mosalekeza lawi, motero kusintha lawi retardancy.
