I-Waterborne Polyurethane Matting Resin

Incazelo emfushane:

I-Aqueous polyurethane isisombululo esinamanzi, ukuhlakazeka noma ukugcoba okunamanzi okwenziwe nge-polyurethane resin emanzini.Isetshenziswa kabanzi ekwakheni, ekhaya, emotweni, ezimpahleni zesikhumba, ezintweni zasendlini kanye nezinye izigqoko zokuhlobisa.I-polyurethane etholakala emanzini ingasetshenziswa ukulungisa ukunamathela.Njengamanje, umphumela wokuhlanganisa we-resin yokunamathisela utholakala ikakhulukazi ngokungeza i-ejenti yokuhlanganisa kanye nokuguqulwa kwe-self matting ye-resin.

Incazelo

Ukwengeza i-ejenti yokulinganisa kunganciphisa ukucwebezela kwe-coating, kodwa i-matting agent ijwayele ukuthungwa, okunciphisa ukuzinza kwe-lotion, futhi uma ukuxuba kungalingani, kunezinkinga ezifana nomehluko ekucwebezeleni kokugqoka.Ngakho-ke, ukuze kuxazululwe imiphumela emibi ebangelwa ukwengezwa kwama-matting agents, abantu baqala ukunaka ucwaningo lwe-polyurethane self matting resin kanye ne-microsphere waterborne polyurethane matting resin ngaphandle kokwengeza ama-matting agents.

1. I-Self Extinction Waterborne Polyurethane Resin

I-self matting resin ibhekisela kunhlaka enamathelayo enomphumela wokuhlangana kwendawo ngemva kokwakheka kwefilimu ngaphandle kokwengeza impushana yokumathela eyengeziwe noma i-wax kunhlaka yokuhlanganisa.I-self matting resin inokuhambisana okuhle namanye ama-resin kanye nenkomba ye-refractive efanayo ngemva kokwakhiwa kwefilimu ngoba izingxenye zayo zinezakhiwo ezifanayo zomzimba namakhemikhali kanye nesakhiwo seqembu lamandla optical ngezinhlayiya ze-agent matting, ezixazulula ngokuphumelelayo izinkinga ezibangelwa ukwengeza i-matting agent.Ngesikhathi esifanayo, ngenxa yokuthi inkomba ye-refractive ye-ejenti yokuhlanganisa eyengeziwe kanye ne-molecule yokumboza ayisetshenzisiwe, izakhiwo zakho kokubili ukuhlangana nokubonakala azikwazi ukucatshangelwa, futhi izidingo zokusetshenziswa kwezinye izigqoko azikwazi ukuhlangana.Ngakho-ke, i-self matting coating resin engasebenzisi i-ejenti yokuhlanganisa yangaphandle idonse ukunaka okukhulu.
I-polyurethane self extinction resin etholakala emanzini ngaphandle kwanoma iyiphi i-ejenti yokuhlanganisa yahlanganiswa nge-hydrazine hydrate post chain extension.Enqubweni ye-futhi, izinhlayiya ezifana ne-matting agent ziyakhiqizwa, futhi izinhlayiya zintanta ngokulinganayo ebusweni befilimu yokunamathisela, okwenza indawo engaphezulu ibe yi-micro rough.Le ndlela ayixazululi kuphela iziphambeko ezibangelwa ukusetshenziswa kwe-ejenti yokulinganisa, kodwa futhi inokuqina okuhle kakhulu kwe-lotion, futhi ingathuthukisa ukumelana nokuxubha, ukugoqa ukugoqa kanye nokuxubha ukusheshisa kwefilimu yokugqoka.Ingasetshenziswa kabanzi embotsheni engaphezulu yesikhumba, i-polyvinyl chloride (PVC) yesikhumba, isikhumba sokwenziwa se-polyurethane, njll.
Ilungelo lobunikazi laseShayina cn106432667b lidalula indlela yokulungiselela ye-self-matting ethambile futhi ezwelayo ephuma emanzini e-polyurethane i-ejenti yokuqedela isikhumba.Ilungelo lobunikazi eliguquliwe lisebenzisa i-hmdi, i-HDI Trimer, i-propylene carbonate glycol ne-dimethylbutyric acid (i-DMBA) njengezinto zokusetshenziswa eziyinhloko kanye ne-hydrazine hydrate njenge-chain extender ngemva kwe-emulsification ukuze kulungiswe i-polyurethane egcwele amanzi.I-HDI Trimer entweni eluhlaza inesakhiwo esiyindandatho samaqembu amathathu asebenzayo.Isakhiwo sendandatho sizinzile ngesikhathi senqubo yokuhlanganisa, engakha isakhiwo senethiwekhi esixhumene ngokuphambanayo kweminye imikhiqizo ye-polyurethane.Ukuhambisana kwejeli elincane elikhiqizwe namanye ama-polyurethane resins kuncipha ngesikhathi senqubo yokwakhiwa kwefilimu.Ngaphezu kwalokho, kunezinga elithile le-crystallinity ku-polyurethane, okuholela ekwehleni kokungafihli kokwakheka kwefilimu, ukufeza umphumela wokuqothulwa kwemaski, nokuthuthukisa kakhulu ukunwebeka, ukumelana kwamanzi, ukumelana ne-solubility kanye nokumelana nokugqoka. ifilimu ye-polyurethane.

2. Ukuguqulwa Kwe-Waterborne Polyurethane Matting Resin

Njengoba ukungezwa kwe-ejenti yokulinganisa kungase kuthinte izakhiwo ezibonakalayo zefilimu yokumboza, futhi amaqembu e-hydrophilic aqukethwe ku-self matting waterborne resin ye-polyurethane azobangela ukumelana kwamanzi okumpofu kwefilimu yokumboza ngemva kokwakhiwa kwefilimu yokugcoba, ikakhulukazi uma isetshenziswa. ukugqoka okuphezulu kwesikhumba noma iphepha, izinkampani eziningi zilungiselela ama-resin matting ngokuguqulwa, njengokuguqulwa kwe-silicone nokuguqulwa kokuxhumanisa.
Enqubweni yokwakhiwa kwefilimu ye-organosilicon modified waterborne polyurethane matting resin, izingxenye ze-hydrophobic organosilicon zithuthela phezu kwefilimu yokugcoba lotion ukuze zenze indawo encane, okwenza i-polyurethane ibe nakho kokubili izinto eziphilayo kanye ne-inorganic, futhi ukumelana kwamanzi, okushisayo. ukuzinza kanye nezakhiwo zemishini zithuthukiswa ngempumelelo.I-Silicone modified waterborne polyurethane matting resin yalungiswa kusetshenziswa i-PDMS modified PTMG, diisocyanate (IPDI) kanye ne-dimethylol propionic acid (DMPA) njengezisetshenziswa zokusetshenziswa.
Ukuguqulwa kwe-crosslinking kushintsha ukwakheka kwe-linear polyurethane, okuwumphumela wokuphambana kwayo ukuze kwakhiwe ama-macromolecules enethiwekhi ye-polyurethane aminyene.Ubukhulu bezinhlayiyana ze-polyurethane lotion buyakhula, futhi amanzi ayahwamuka phakathi nenqubo yokomisa yokugcoba.Izibonelo ezinodayamitha okhudlwana zakha indawo emangelengele kanye nesicwebezelisi esiphansi ngemva kokunqwabelana.Ngesikhathi esifanayo, ukumelana nokushisa, ukumelana namanzi kanye nokumelana namakhemikhali e-polyurethane elungiselelwe emanzini nakho kwathuthukiswa ngenxa yesakhiwo senethiwekhi esixhumene kakhulu.I-self extinction lotion ye-waterborne polyurethane elungiswe ngokuphambana kwangaphakathi yalungiswa ngendlela yokwandisa iketango leposi.Indawo yefilimu yayimaholo.

Amazwi okuphetha

Njengesici esibalulekile sokusetshenziswa kwe-polyurethane resin emanzini, i-matting coating resin inakwe imboni yokuhlanganisa.Kodwa-ke, eminye imikhiqizo ayinakho ukuzinza okuhle.Njengoba asikho isidingo sokwengeza i-ejenti yokuhlanganisa embotsheni, i-self matting coating resin inokuqina okuqinile nokusebenza okuhle kakhulu kokunamathela, okuzoba umkhuba wokuthuthukiswa esikhathini esizayo.
