1. La'au Lafoa'i
I le avea ai o se ituaiga fou o le polymer, o le polymer hyperbranched o loʻo i ai se fausaga faʻapolofesa, o se numera tele o vaega faʻaiʻuga ma e leai se taamilo i le va o filifili mole.O polymers Hyperbranched e iai le lelei o le faʻamavaeina faigofie, maualalo le faʻafefeteina, maualalo le viscosity ma le maualuga o le gaioiga.O le mea lea, o vaega acryloyl ma vaega hydrophilic e mafai ona faʻafeiloaʻi e faʻapipiʻi moli vai faʻamalolo oligomers, lea e tatalaina ai se auala fou mo le saunia o le vai UV resin.
O se polyester (whpua) e mafai ona togafitia i le vai e mafai ona togafitia i le UV na saunia e ala i le tali a le Hyperbranched Polyester e mauoa i vaega hydroxyl ma succinic anhydride ma ipdi-hea prepolymer, ma mulimuli ane fa'amuta i le amine fa'aola e fai masima.O fa'ai'uga o lo'o fa'aalia ai o le fua fa'amama mama o le resin e vave ma lelei mea fa'aletino.Faatasi ai ma le faateleina o mea faigata vaega, o le vevela suiga tioata o le resin faateleina, o le maaa ma le malosi tensile faateleina foi, ae o le elongation i le malologa ua faaitiitia.O polyesters lapopoa sa saunia mai polyanhydrides ma monofunctional epoxides.Glycidyl methacrylate na faʻafeiloaʻi e faʻafeiloaʻi atili i vaega hydroxyl ma carboxyl o polymers hyperbranched.Mulimuli ane, na fa'aopoopoina le triethylamine e fa'apa'u ma fau masima e maua mai ai le vai e mafai ona fa'amaloloina i le vai polyesters.O faʻaiʻuga na faʻaalia ai o le tele o le vaega o le carboxyl i totonu o le pito o le resini hyperbranched faʻavae vai, o le sili atu lea o le solubility vai;Ole fua ole fa'amaloloina ole resin e fa'atupula'ia i le si'itia o fa'amau fa'alua fa'amau.
2 faiga fa'ato'aga fa'a-inorganic
Ole moli ole vai ole UV ua fa'amālōlōina fa'aola fa'aola / fa'aonapola fa'apipi'i ose fa'afefiloi lelei ole vai ole UV ole vai ma mea fa'aleaganu'u.O le lelei o mea faʻapitoa e pei o le maualuga o le ofuina ma le maualuga o le tau o loʻo faʻafeiloaʻi i totonu o le resin e faʻaleleia atili ai meatotino o le ata faʻamalolo.E ala i le tuʻuina atu o mea faʻapitoa e pei o le nano-SiO2 poʻo le montmorillonite i totonu o le faʻamaloloina o le UV e ala i le faʻasalalau tuusaʻo, metotia sol-gel poʻo le auala faʻafesoʻotaʻi, e mafai ona saunia le UV curing organic / inorganic hybrid system.E le gata i lea, e mafai ona faʻafeiloaʻi le monomer organosilicon i totonu o le filifili mole o le oligomer UV aqueous.
Organo / inorganic hybrid lotion (Si PUA) na saunia e ala i le tuʻuina atu o vaega polysiloxane i le vaega vaivai o le polyurethane faʻatasi ai ma le lua faʻauʻu hydroxybutyl polydimethylsiloxane (PDMS) ma faʻafefe i monomers acrylic.A maeʻa ona faʻamalolo, o le ata vali e iai mea lelei faʻaletino, maualuga faʻafesoʻotaʻi ma faʻafefe vai.O le polyurethane hybrid hyperbranched ma le polyurethane hyperbranched mama mama na saunia mai polyhydroxy hyperbranched polyurethane na faia e le tagata lava ia, succinic anhydride, silane so'o fa'atasi KH560, glycidyl methacrylate (GMA) ma le hydroxyethyl methacrylate.Ona saunia lea o le Si02 / Ti02 organic-inorganic hybrid sol of light cured hyperbranched polyurethane na saunia e ala i le faʻafefiloi ma le faʻafefeteina ma le tetraethyl orthosilicate ma le n-butyl titanate i vaega eseese.O fa'ai'uga o lo'o fa'aalia ai o le fa'atuputeleina o mea fa'aletino, e fa'atupula'ia ai le ma'a'a'a o le pa'u fa'apipi'i ma fa'atupula'ia le talatala.O le tulaga maualuga o le SiO2 hybrid coating e sili atu nai lo le Ti02 hybrid coating.
3 faiga fa'amalolo lua
Ina ia mafai ona foia le faaletonu o le tolu-dimensional curing o Waterborne UV resin ma faamaloloina o le mafiafia o le ufiufi ma le faiga lanu, ma faaleleia le atoatoa o meatotino o le ata tifaga, tagata suʻesuʻe na atiina ae se faiga faamalolo lua tuufaatasia le malamalama faamalolo ma isi faiga faamalolo.I le taimi nei, faʻamalama faʻamalama, faʻamaʻi vevela, faʻamaʻi mama / redox faʻamaʻi, faʻamaʻi faʻamalama faʻamalama / faʻamalama faʻamalama cationic ma faʻamaʻi mama / faʻamalolo susu o faiga masani faʻamalolo lua, ma o nisi faiga ua faʻaaogaina.Mo se fa'ata'ita'iga, UV fa'apipi'i fa'aeletonika fa'aeletonika ose faiga fa'amalolo lua o le fa'amalolo mama / redox po'o le fa'amalolo mama/fa'amalolo susu.
O le monomer ethyl acetoacetate methacrylate (amme) galue na faʻafeiloaʻi i le polyacrylic acid lotion, ma o le vaega faʻamalama malamalama na faʻafeiloaʻi e ala i Michael faʻaopoopo tali i le maualalo o le vevela e faʻapipiʻi ai le vevela / uv curing waterborne polyacrylate.Fa'agogo i le vevela faifaipea o le 60 ° C, 2 x 5 I lalo o le tulaga o le 6 kW maualuga-omiomi moli mercury irradiation, o le maaa o le resin pe a uma ona faia ata tifaga o le 3h, o le ava malosi e 158 taimi, ma le alkali tetee o le 24 itula.
4 epoxy acrylate / polyurethane acrylate faiga tu'ufa'atasi
Epoxy acrylate coating o loʻo i ai le lelei o le maualuga o le maaa, faʻapipiʻi lelei, maualuga le iila ma le lelei o vailaʻau, ae e le lelei le fetuutuunai ma le brittleness.Waterborne polyurethane acrylate o loʻo i ai uiga o le lelei o le ofuina ma le fetuutuunai, ae leaga le tau.O le faʻaaogaina o vailaʻau faʻasolosolo, faʻafefiloi faʻaletino poʻo auala faʻapipiʻi e faʻapipiʻi lelei ai resini e lua e mafai ona faʻaleleia le faʻatinoga o se resini e tasi ma tuʻuina atu le taʻaloga atoa i o latou lelei, ina ia mafai ai ona atiaʻe se faiga faʻamalolo UV maualuga ma mea lelei uma e lua.
5 macromolecular poʻo polymerizable photoinitiator
O le tele o photoinitiators o aryl alkyl ketone laiti molelaʻau, e le mafai ona pala atoa pe a uma le fofo mama.O vaega laiti o totoe po'o mea o le photolysis o le a alu atu i luga o le ufiufi, e mafua ai le samasama poʻo le manogi, lea o le a aʻafia ai le faʻatinoga ma le faʻaogaina o le ata faʻamalolo.E ala i le faʻaofiina o photoinitiators, vaega acryloyl ma vaega hydrophilic i polymers hyperbranched, tagata suʻesuʻe synthesized waterborne macromolecular polymerizable photoinitiators e foia ai le le lelei o tamai photoinitiators molecular.
