I-Polyurethane Matting Resin yasemanzini

1. I-Self Extinction Waterborne Polyurethane Resin

I-resin yokulinganisa i-self matting ibhekiselele kwi-resin yokwambathisa enefuthe lokulinganisa umphezulu emva kokwenziwa kwefilimu ngaphandle kokongeza umgubo wokulinganisa owongezelelweyo okanye i-wax kwi-resin yokwambathisa.I-self matting resin inokuhambelana kakuhle kunye nezinye ii-resin kunye ne-index ye-refractive efanayo emva kokubunjwa kwefilimu ngenxa yokuba amacandelo ayo aneempawu ezifanayo zomzimba kunye neekhemikhali kunye nesakhiwo seqela lamandla okukhanya kunye neengqungquthela ze-agent matting, ezisombulula ngempumelelo iingxaki ezibangelwa ukongeza i-agent matting.Ngexesha elifanayo, ngenxa yokuba isalathisi esihlaziyiweyo se-agent edibeneyo yokudibanisa kunye ne-molecule yokugqoka ayisetyenziswanga, iipropathi zombini kunye ne-transparency azikwazi ukuqwalaselwa, kwaye iimfuno zesicelo zezinye iingubo azikwazi ukuhlangabezana nazo.Ke ngoko, i-resin yokwambathisa yokuzimela engasebenzisi arhente yokumata yangaphandle iye yatsala umdla omkhulu.
I-waterborne polyurethane self extinction resin ngaphandle kwe-agent yokulinganisa yenziwe nge-hydrazine hydrate post chain extension.Kwinkqubo kunye, amaqhekeza afana ne-agent agent ayenziwa, kwaye iinqununu zihamba ngokulinganayo phezu kwefilimu enamathelayo, okwenza umphezulu we-micro rough.Le ndlela ayisombululi kuphela iziphene ezibangelwa kukusetyenziswa kwe-agent yokulinganisa, kodwa inozinzo oluhle kakhulu lwe-lotion, kwaye inokuphucula ukuxhathisa ukuxubha, ukukhawuleza ukugoba kunye nokuxubha ngokukhawuleza kwefilimu yokugqoka.Inokuthi isetyenziswe ngokubanzi kwi-surface coating yesikhumba, i-polyvinyl chloride (PVC) yesikhumba, i-polyurethane yesikhumba eyenziweyo, njl.
Ilungelo elilodwa lomenzi wechiTshayina cn106432667b lidiza indlela yokulungiselela ukuzincamathela okuthambileyo kunye novakalelo lwe-agent egqibezela ufele lwe-polyurethane emanzini.I-patent elungisiweyo isebenzisa i-hmdi, i-HDI Trimer, i-propylene carbonate glycol kunye ne-dimethylbutyric acid (i-DMBA) njengezinto eziphambili kunye ne-hydrazine hydrate njenge-chain extender emva kwe-emulsification ukulungiselela i-matting waterborne polyurethane.I-HDI Trimer kwi-raw material inesakhiwo sendandatho samaqela amathathu asebenzayo.Ulwakhiwo lwendandatho luzinzile ngexesha lenkqubo yokudibanisa, enokwenza i-cross-linked network structure kwezinye iimveliso ze-polyurethane.Ukuhambelana kwejeli encinci eyenziweyo kunye nezinye i-polyurethane resins kuyancipha ngexesha lenkqubo yokwenziwa kwefilimu.Ukongeza, kukho inqanaba elithile lecrystallinity kwi-polyurethane, ekhokelela ekunciphiseni ukucaca kokwakheka kwefilimu, ukufikelela kwisiphumo sokuphela kwemaski, kunye nokuphucula kakhulu ukuqina, ukuxhathisa kwamanzi, ukuxhathisa ukunyibilika kunye nokumelana nokunxiba. ifilimu ye-polyurethane.

2. Ukuguqulwa kwe-Polyurethane Matting Resin yasemanzini

Ekubeni ukongezwa kwe-agent yokudibanisa kunokuchaphazela iipropati ezibonakalayo zefilimu yokugqoka, kunye namaqela e-hydrophilic aqulethwe kwi-self matting ye-polyurethane resin yamanzi iya kubangela ukunganyangeki kwamanzi kwifilimu yokugquma emva kokusekwa kwefilimu yokuthambisa, ngakumbi xa isetyenziswa. Ukugqoka okuphezulu kwesikhumba okanye iphepha, iinkampani ezininzi zilungiselela i-resins yokudibanisa ngokuguqulwa, njengokuguqulwa kwe-silicone kunye nokuguqulwa kwe-cross-linking.
Kwinkqubo yokwenziwa kwefilimu ye-organosilicon eguqulweyo ye-waterborne polyurethane matting resin, amacandelo e-hydrophobic organosilicon afudukela kumphezulu wefilimu yokugquma ifilimu ukuze enze umphezulu omncinci orhabaxa, owenza ukuba i-polyurethane ibe nazo zombini iipropati ze-organic kunye ne-inorganic, kunye nokumelana namanzi, i-thermal. uzinzo kunye neempawu zoomatshini ziphuculwa ngokufanelekileyo.I-Silicone eguqulelwe ngamanzi e-polyurethane matting resin yalungiswa ngokusebenzisa i-PDMS elungisiweyo ye-PTMG, i-disocyanate (IPDI) kunye ne-dimethylol propionic acid (DMPA) njengezinto eziphathekayo.
Ukuguqulwa kwe-crosslinking kutshintsha isakhiwo se-linear polyurethane, esisisiphumo sokudibanisa kwayo ukwenza i-network polyurethane macromolecules eshinyeneyo.Ubungakanani be-particle ye-polyurethane lotion iyanda, kwaye amanzi aphuphuma ngexesha lokumisa kwe-lotion.Imizekelo enedayamitha enkulu yenza umphezulu orhabaxa kunye neglosi ephantsi emva kokupakishana.Kwangaxeshanye, ukumelana nobushushu, ukunganyangeki kwamanzi kunye nokumelana neekhemikhali zepolyurethane elungiselelwe amanzi nayo yaphuculwa ngenxa yesakhiwo esixineneyo sonxibelelwano lomnatha.I-self extinction lotion ye-waterborne polyurethane eguqulwe ngokudibanisa kwangaphakathi yalungiswa nge-post chain extension method.Umphezulu wefilimu wawurhabaxa.

Amagqabantshintshi okuphetha

Njengomba obalulekileyo wokusetyenziswa kwe-polyurethane resin yamanzi, i-resin yokugqoka i-matting inikwe ingqalelo yi-coating industry.Nangona kunjalo, ezinye iimveliso zinozinzo olubi.Kuba akukho mfuneko yokongeza i-ejenti yokwaleka kwi-coating, i-resin yokwaleka i-self matting inozinzo olomeleleyo kunye nokusebenza okugqwesileyo kokwambathisa, okuya kuba yindlela yophuhliso kwixesha elizayo.
