Madzi a Polyurethane Matting Resin

Kufotokozera Kwachidule:

Aqueous polyurethane ndi njira yamadzimadzi, kubalalitsidwa kapena mafuta odzola amadzimadzi opangidwa ndi utomoni wa polyurethane m'madzi.Amagwiritsidwa ntchito kwambiri pomanga, nyumba, galimoto, zovala zachikopa, zipangizo zapakhomo ndi zokutira zina zokongoletsera.Madzi a polyurethane amatha kugwiritsidwa ntchito pokonzekera zokutira.Pakalipano, mphamvu ya matting ya utomoni wokutira imapezeka makamaka powonjezera chopangira matting ndi kusintha kwa utomoni wokha.

Kuonjezera matting agent kungathe kuchepetsa gloss ya zokutira, koma matting agent amatha kusungunuka, zomwe zimachepetsa kukhazikika kwa mafuta odzola, ndipo ngati kusakaniza kuli kosiyana, pali mavuto monga kusiyana kwa gloss ya zokutira.Choncho, pofuna kuthetsa mavuto omwe amabwera chifukwa cha kuwonjezera kwa matting agents, anthu anayamba kumvetsera kafukufuku wa madzi a polyurethane self matting resin ndi microsphere waterborne polyurethane matting resin popanda kuwonjezera zowonjezera.

1. Self Extinction Waterborne Polyurethane Resin

Utoto wa Self matting umatanthawuza utomoni wokutira womwe umakhala ndi mphamvu yopindika pambuyo pakupanga filimu popanda kuwonjezera ufa kapena sera ku utomoni wokutira.The self matting resin imagwirizana bwino ndi ma resins ena ndi index yofananira yofananira pambuyo pakupanga filimu chifukwa zigawo zake zimakhala ndi mawonekedwe ofanana ndi thupi ndi mankhwala komanso mawonekedwe a gulu lamphamvu lokhala ndi tinthu tating'onoting'ono, zomwe zimathetsa bwino mavuto omwe amadza chifukwa chowonjezera chothandizira.Panthawi imodzimodziyo, chifukwa chakuti chiwerengero cha refractive cha chowonjezera chowonjezera ndi molekyu yophimba sichigwiritsidwa ntchito, katundu wa matting ndi kuwonekera sizingaganizidwe, ndipo zofunikira zogwiritsira ntchito zokutira zina sizingatheke.Chifukwa chake, utomoni wodzipaka okha womwe sugwiritsa ntchito chotchingira chakunja wakopa chidwi.
Madzi a polyurethane self extinction resin popanda chotengera chilichonse adapangidwa ndi hydrazine hydrate post chain extension.M'kati mwa ndi, particles ofanana matting wothandizira amapangidwa, ndi particles tiwolokere wogawana pamwamba pa zomatira filimu, kupanga padziko yaying'ono akhakula.Njirayi sikuti imathetsa zolakwika zomwe zimayambitsidwa ndi kugwiritsa ntchito matting wothandizira, komanso zimakhala ndi kukhazikika kwa mafuta odzola, komanso zimatha kusintha kukana kupaka, kupukuta mofulumira komanso kupukuta filimuyo.Iwo akhoza ankagwiritsa ntchito kwa ❖ kuyanika pamwamba zikopa, polyvinyl kolorayidi (PVC) zikopa, polyurethane yokumba chikopa, etc.
Patent yaku China cn106432667b imawulula njira yokonzekera yodziphatika yokhayokha yofewa komanso yowoneka bwino ya polyurethane chikopa chamadzi.Patent yosinthidwa imagwiritsa ntchito hmdi, HDI Trimer, propylene carbonate glycol ndi dimethylbutyric acid (DMBA) monga zida zazikulu zopangira ndi hydrazine hydrate monga unyolo wowonjezera pambuyo pa emulsification kukonzekera matting waterborne polyurethane.HDI Trimer muzopangira zili ndi mphete yamagulu atatu ogwira ntchito.Mapangidwe a mphete amakhala okhazikika panthawi ya kaphatikizidwe, omwe amatha kupanga mawonekedwe olumikizana ndi maukonde pazinthu zina za polyurethane.Kugwirizana kwa gel osakaniza opangidwa ndi ma polyurethane resins kumachepetsedwa panthawi yopanga filimu.Komanso, pali mlingo wina wa crystallinity mu polyurethane, zomwe zimabweretsa kuchepa kwa kuwonekera kwa filimu mapangidwe, kukwaniritsa kutha kwa chigoba, ndi bwino kwambiri elasticity, kukana madzi, solubility kukana ndi kuvala kukana. filimu ya polyurethane.

2. Kusintha Kwa Madzi a Polyurethane Matting Resin

Popeza Kuwonjezera matting wothandizira zingakhudze thupi katundu ❖ kuyanika filimu, ndi magulu hydrophilic zili mu kudzikonda matting waterborne utomoni polyurethane kuchititsa osauka kukana madzi ❖ kuyanika filimu pambuyo mapangidwe lotion filimu, makamaka pamene ntchito. pakuphimba pamwamba pa chikopa kapena pepala, makampani ambiri amakonzekera ma resin posintha, monga kusinthidwa kwa silikoni ndikusintha kolumikizana.
Mu ndondomeko ya filimu mapangidwe organosilicon kusinthidwa waterborne polyurethane matting utomoni, ndi hydrophobic organosilicon zigawo amasamukira pamwamba pa lotion ❖ kuyanika filimu kupanga yaying'ono akhakula pamwamba, zomwe zimapangitsa polyurethane kukhala zonse organic ndi inorganic katundu, ndi kukana madzi, matenthedwe. bata ndi makina katundu bwino bwino.Silicone modified waterborne polyurethane matting resin inakonzedwa pogwiritsa ntchito PDMS yosinthidwa PTMG, diisocyanate (IPDI) ndi dimethylol propionic acid (DMPA) monga zipangizo.
The crosslinking kusinthidwa amasintha dongosolo la liniya polyurethane, amene ndi chifukwa cha crosslinking ake wandiweyani maukonde polyurethane macromolecules.Kukula kwa tinthu ta polyurethane mafuta odzola kumawonjezeka, ndipo madzi amasanduka nthunzi pa kuyanika kwa mafuta odzola.Zitsanzo zokhala ndi mainchesi okulirapo zimapanga zowoneka bwino komanso zonyezimira pang'ono pambuyo pomangana wina ndi mnzake.Nthawi yomweyo, kukana kutentha, kukana madzi ndi kukana kwa mankhwala a polyurethane okonzeka m'madzi kunasinthidwanso chifukwa cha mawonekedwe olumikizana ndi netiweki.The self extinction lotion of waterborne polyurethane modified by internal crosslinking inakonzedwa ndi post chain extension njira.Pamwamba pa filimuyi panali zovuta.

Mawu Omaliza

Monga gawo lofunikira pakugwiritsa ntchito utomoni wa polyurethane m'madzi, utomoni wopaka mating waperekedwa chidwi ndi makampani okutira.Komabe, zinthu zina zimakhala zosakhazikika bwino.Popeza palibe chifukwa chowonjezera chopangira chotchingira mu zokutira, utomoni wodzipaka wokhawokha uli ndi kukhazikika kwamphamvu komanso magwiridwe antchito abwino kwambiri, zomwe zidzakhale chitukuko mtsogolo.
