1. Hyperbranched system
Serudzi rutsva rwepolymer, hyperbranched polymer ine spherical chimiro, huwandu hukuru hweanoshingaira ekupedzisira mapoka uye pasina mhepo pakati pemamorekuru cheni.Hyperbranched mapolymers ane zvakanakira kunyungudika nyore, yakaderera kunyungudika, yakaderera viscosity uye yakakwirira reactivity.Naizvozvo, mapoka e acryloyl uye mapoka e hydrophilic anogona kuunzwa kuti agadzire maoligomers emvura anorapa chiedza, izvo zvinovhura nzira itsva yekugadzirira kweWaterborne UV resin.
Iyo UV inorapika yemvura hyperbranched polyester (whpua) yakagadzirirwa nekuita kweHyperbranched Polyester yakapfuma mumapoka ehydroxyl ane succinic anhydride uye ipdi-hea prepolymer, uye pakupedzisira yakagadziriswa neorganic amine kugadzira munyu.Mhedzisiro yacho inoratidza kuti mwenje wekuporesa mwero weresin unokurumidza uye zvimiro zvemuviri zvakanaka.Nekuwedzera kwechikamu chakaoma chemukati, tembiricha yegirazi resin inowedzera, kuoma uye kusimba kwesimba kunowedzerawo, asi kureba panguva yekuzorora kunoderera.Hyperbranched polyesters yakagadzirwa kubva ku polyanhydrides uye monofunctional epoxides.Glycidyl methacrylate yakaunzwa kuti iwedzere kuita ne hydroxyl uye carboxyl mapoka e hyperbranched polymers.Chekupedzisira, triethylamine yakawedzerwa kuti isaite munyu uye kuita munyu kuti iwane UV inorapika inorapika mumvura hyperbranched polyesters.Mhedzisiro yacho yakaratidza kuti kana iyo yakawanda yeboka recarboxyl iri mumagumo emvura-based hyperbranched resin, zviri nani kunyungudika kwemvura;Muyero wekurapa we resin unowedzera nekuwedzera kweiyo terminal kaviri mabhondi.
2 organic-inorganic hybrid system
Mvura yakasvibirira UV mwenje yakarapwa organic / inorganic hybrid system inoshanda inoumbwa yeWaterborne UV resin uye inorganic zvinhu.Zvakanakira zveinorganic zvinhu zvakaita seyepamusoro kupfeka kuramba uye yakakwirira yemamiriro ekunze kuramba inounzwa muresin kuti ivandudze huwandu hwakazara hweiyo firimu rakarapwa.Nekuunza inorganic particles senge nano-SiO2 kana montmorillonite muUV yekurapa sisitimu kuburikidza yakananga dispersion nzira, sol-gel nzira kana intercalation nzira, iyo UV yekurapa organic / inorganic hybrid system inogona kugadzirwa.Uye zvakare, iyo organosilicon monomer inogona kuunzwa mune molecular cheni yeaqueous UV oligomer.
Organo / inorganic hybrid lotion (Si PUA) yakagadzirirwa nekuunza mapoka epolysiloxane muchikamu chakapfava che polyurethane ine maviri terminal hydroxybutyl polydimethylsiloxane (PDMS) uye diluting nema acrylic monomers.Mushure mekuporesa, firimu repende rine zvinhu zvakanaka zvemuviri, high contact angle uye kudzivirira mvura.Hyperbranched hybrid polyurethane uye chiedza chakarapwa hyperbranched polyurethane zvakagadzirirwa kubva kune yega-yakagadzirwa polyhydroxy hyperbranched polyurethane, succinic anhydride, silane coupling agent KH560, glycidyl methacrylate (GMA) uye hydroxyethyl methacrylate.Zvadaro, Si02 / Ti02 organic-inorganic hybrid sol yechiedza yakarapwa hyperbranched polyurethane yakagadzirwa nekusanganisa uye hydrolyzing ne tetraethyl orthosilicate uye n-butyl titanate muzvikamu zvakasiyana.Mhedzisiro yacho inoratidza kuti nekuwedzera kweiyo inorganic content, iyo pendulum kuomarara kweiyo hybrid coating inowedzera uye iyo roughness yekumusoro inowedzera.Hunhu hwepamusoro hweSiO2 hybrid coating huri nani pane hweTi02 hybrid coating.
3 mbiri yekurapa system
Kugadzirisa kusakwana kweatatu-dimensional kurapa kweWaterborne UV resin uye kurapa kweakakora coating uye ane mavara sisitimu, uye nekuvandudza huwandu hwezvinhu zvefirimu, vaongorori vakagadzira huviri hwekurapa system inosanganisa kurapa kwechiedza nemamwe masisitimu ekurapa.Parizvino, kurapa mwenje, kurapa kwekupisa, kurapa mwenje / redox kurapa, mahara radical mwenje kurapa / cationic mwenje kurapa uye mwenje kurapa / wet kurapa zvakajairika maviri maviri ekurapa masisitimu, uye mamwe masisitimu akaiswa.Semuenzaniso, UV yemagetsi inodzivirira inonamira ndeye mbiri yekurapa sisitimu yemwenje kurapa / redox kana mwenje kurapa / kunyorova kurapa.
Iyo inoshanda monomer ethyl acetoacetate methacrylate (amme) yakaunzwa mupolyacrylic acid lotion, uye boka rekuporesa mwenje rakaunzwa kuburikidza naMichael wekuwedzera maitiro pakudziya kwakadzika kubatanidza kupisa kurapa / uv kurapa inotakura mvura polyacrylate.Dry paanogara tembiricha ye60 ° C, 2 x 5 Pasi pemamiriro e6 kW high-pressure mercury rambi irradiation, kuoma kweresin mushure mekugadzirwa kwefirimu ndeye 3h, kupikisa doro kunosvika 158 nguva, uye alkali resistance is 24. maawa.
4 epoxy acrylate / polyurethane acrylate composite system
Epoxy acrylate coating ine zvakanakira kuomarara kwepamusoro, kunamatira kwakanaka, kupenya kwepamusoro uye kunaka kwemakemikari kuramba, asi ine kusachinja-chinja uye brittleness.Waterborne polyurethane acrylate ine hunhu hwekunaka kupfeka kuramba uye kuchinjika, asi kushomeka kwemamiriro ekunze.Kushandisa gadziriso yemakemikari, kusanganisa kwemuviri kana nzira dzemahybrid kunyatsobatanidza marezeni maviri anogona kuvandudza mashandiro eresin imwechete uye kupa kutamba kwakazara kune zvakanakira zvawo, kuitira kuti igadzire yakanyanya-inoshanda UV yekurapa system ine zvese zvakanaka.
5 macromolecular kana polymerizable photoinitiator
Mazhinji mafotoinitiators ari aryl alkyl ketone mamorekuru madiki, asingagone kuparara zvachose mushure mekupora kwechiedza.Iwo asara mamorekuru madiki kana zvigadzirwa zvephotolysis zvinotamira kunzvimbo yekuputira, zvichikonzera yero kana kunhuwa, izvo zvinokanganisa kuita uye kushandiswa kwefirimu rakarapwa.Nekuunza mafotoinitiators, mapoka eacryloyl uye mapoka ehydrophilic kuita hyperbranched polymers, vaongorori vakagadzira macromolecular polymerizable photoinitiators kuti vakunde zvakaipira madiki mamorekuru photoinitiators.
