Polyether polyurethane acrylate rau yas txheej

Yam khoom: ZC6202

Khoom ZC6202 yog cov khoom lag luam ntawm lub tuam txhab.Nws lub npe tshuaj yog polyether polyurethane acrylate.Nws yog cov kua dej tsis muaj xim lossis daj daj uas muaj qhov yooj yim thiab adhesion.Nws yog tsuas yog siv rau ntawv, yas txheej thiab ntoo adhesion primer.Aromatic polyurethane acrylate

Ntxiv polyether (polyester) diol thiab polymerization inhibitor rau hauv plaub qhov chaw nres nkoj flask nruab nrog nplawm tshuab, ntsuas kub thiab condenser raj, do sib npaug, ces ntxiv TDI, nce qhov kub ntawm 70-80 ℃ rau cov tshuaj tiv thaiv rau 1.5 teev, kuaj pom tus nqi NCO, Tom qab ntawd ntxiv hydroxyethyl acrylate (hydroxypropyl acrylate), ntxiv cov catalyst, txuas ntxiv cov tshuaj tiv thaiv rau 3 teev, thiab kuaj pom tias NCO tus nqi sib npaug li 0. Lub viscosity ntawm aromatic polyurethane acrylate tau ntsuas los ntawm cov qauv, thiab kev ua haujlwm ntawm aromatic polyurethane acrylate raug kuaj. los ntawm kev ntxiv 3% - 4% photoinitiato.Thov cia qhov chaw txias los yog qhuav, thiab zam lub hnub thiab cua sov; Cia kub tsis pub tshaj 40 ºC, cia tej yam kev mob nyob rau hauv ib txwm tej yam kev mob rau tsawg kawg yog 6 lub hlis.

Pib nrog polyethylene glycol (PEG, MW 1000) ε- Caprolactone ( ε- Cov ntu mos ntawm polyether ester block copolymer diol (pCEC) tau npaj los ntawm lub nplhaib qhib, reacted nrog diisocyanate (toluene diisocyanate los yog diphenylmethane diisocyanate methyl methyl methyl) kho kom tau txais cov khoom siv polyether ester polyurethane acrylate (PUA) Cov khoom sib xyaw thiab cov qauv ntawm PUA tau tshwm sim Cov txiaj ntsig tau pom tias nce PCL ntu tuaj yeem txhim kho cov crystallinity ntawm PUA cov khoom, tab sis txo cov dej nqus thiab degradation tus nqi enzymatic hydrolysis ntawm PUA siab dua. tshaj li ntawm PUA Pcec2000-tdi cov khoom muaj hydrophilicity thiab degradation kev ua tau zoo.Kev nqus dej yog siab li 65.24% hauv 72 teev thiab tuaj yeem degraded tag nrho hauv cov tshuaj enzyme hauv 11 lub lis piam Cov khoom siv PUA no muaj peev xwm siv tau rau hauv cov ntaub so ntswg engineering.
