Epoxy acrylate resin, oo sidoo kale loo yaqaanno vinyl ester resin, waa resin epoxy la beddelay kaas oo lagu milmay styrene ka dib falcelinta resin epoxy iyo acrylic acid;Epoxy acrylate resin waxa uu leeyahay sifooyinkii ugu wanagsanaa ee xabagta epoxy, laakiin daawaynta iyo qaabaynta ayaa ka wanaagsan.Ma aha mid dhib badan sida resin epoxy.Waa resin daaweeya kulaylka.Waxay leedahay iska caabbinta biyaha oo aad u fiican, caabbinta biyaha kulul, caabbinta daroogada, dhejinta iyo adkaanta.Waxaa lagu daweyn karaa habka daaweynta peroxide organic (heerkulka hooseeya ee heerkulka sare) ama habka daaweynta iftiinka, waxaana si weyn loogu isticmaalaa meelaha soo socda: alaabada FRP u adkaysata daxalka, sida taangiyada FRP, tuubooyinka, munaaradaha iyo xadhkaha u adkaysta;Ka-hortagga daxalka wuxuu u shaqeeyaa, sida sibidhka ama birta ku salaysan fiber galaas ah oo la xoojiyay dahaarka caagga ah, dabaqa u adkaysta daxalka sare;FRP awood sare leh, sida muuqaalada FRP-ga jeexan, alaabta ciyaaraha, doomaha FRP, iwm;Dahaar culus oo ka-hortagga daxalka dhalada;Kuwa kale sida khad UV, dabaqa warshadaha culus ee ka hortagga daxalka, iwm.
Isku-dubbaridka epoxy acrylate ayaa la dammaanad qaaday 1950-meeyadii, laakiin laguma dabaqin goobta daaweynta UV ilaa 1970-yadii.Epoxy acrylate waxa laga sameeyaa resin epoxy-ganacsiyeedka iyo acrylic acid ama methacrylate, kaas oo ah nooc ka mid ah UV daawaynta oligomer oo leh isticmaalka balaadhan ee warshadaha daweynta UV ee gudaha wakhtigan;Sida laga soo xigtay nooca qaab-dhismeedka, epoxy acrylate waxa loo qaybin karaa bisphenol A epoxy acrylate, phenolic epoxy acrylate, epoxy acrylate la beddelay iyo acrylate saliid epoxidized.
Qaab dhismeedka molecular ee bisphenol A epoxy acrylate wuxuu ka kooban yahay giraan udgoon iyo kooxda hydroxyl dhinac, taas oo u fiican hagaajinta adhesion, halka adhesion of aliphatic epoxy acrylate liidata;Qaab dhismeedka giraanta udgoonka ayaa sidoo kale ku siinaya resin adag adag, xoog jilicsan iyo xasilloonida kulaylka.
Epoxy acrylate waa prepolymer UV ah oo si weyn loo isticmaalo.Marka la eego qaab-dhismeedka, waxa loo qaybin karaa bisphenol A epoxy acrylate, phenolic epoxy acrylate, acrylate oil epoxidized iyo epoxy acrylate la beddelay.Sida xabagta ugu weyn, filimka epoxy acrylate ee la daweeyay wuxuu leeyahay adhesion wanaagsan, caabbinta kiimikada iyo xoogga, laakiin sidoo kale waxaa jira cillado, sida dabacsanaan ku filan iyo jajabnaanta sare ee filimka la daaweeyay.Sidaa darteed, si loo daboolo baahiyaha dhinacyo kala duwan, wax ka beddelka (jirka iyo/ama kiimikaad) ee epoxy acrylate waxay noqotay mid ka mid ah cilmi-baadhisyada diiradda saaraya goobtan.
Daboolida epoxy acrylate waxay xaddidaysaa codsigeeda microelectronics iyo meelaha kale.Dahaarka dabiiciga ah, dib u dhigista ololku sidoo kale aad bay muhiim u tahay.Ku darida isku-dhafka fosfooraska waxay wanaajin kartaa dib u dhaca ololka.Marka lakabka sare ee polymer-ka uu gubto, fosfooraska ku jira isku-dhafka ayaa balaadhin doona, mugga ayaa kordhi doona, gudaha polymer-ka wuxuu noqon doonaa mid ka madax bannaan gubasho joogto ah oo ololka ah, sidaas darteed hagaajinta dabka.
