I-Synthesis ye-UV enyangekayo ye-Acrylate ye-Acrylate ye-Acrylate ye-Acrylate ye-UV enomfanekiso obonakalayo

I-Synthesis ye-UV enyangekayo ye-Acrylate ye-Acrylate ye-UV

Inkcazelo emfutshane:

I-Uv-wpua i-coating yenziwe nge-oligomer, i-photoinitiator, i-diluent esebenzayo, njl.Ubume bayo bumisela iimpawu ezisisiseko zefilimu yokunyanga ye-UV, njengokuqina, ukuguquguquka, ukumelana nokunxiba, ukuxhathisa kwamanzi kunye nokuxhathisa ukubola.I-Photoinitiator licandelo elibalulekileyo lenkqubo yokunyanga ye-UV, edlala indima ebalulekileyo kubuntununtunu benkqubo yokunyanga ye-UV kwaye ikwachaphazela ukusebenza kokugqibela kwefilimu enyangisiweyo.Ukugquma kwe-Uv-wpua kusebenzisa amanzi njenge-diluent esebenzayo, enciphisa kakhulu ukusetyenziswa kwezinyibilikisi eziphilayo.

Ukuhlanganiswa kwe-Acrylate ye-Acrylate yamanzi

I-oligomer kwi-uv-wpua i-wpua yi-wpua, eyona nxalenye ephambili yokugqoka.I-Wpua ngokuqhelekileyo yenziwa ngokusabela kwe-polyisocyanate, i-diol kunye ne-hydroxyl acrylate.I-Isocyanates ibandakanya i-isocyanates enevumba elimnandi, i-aliphatic isocyanates kunye ne-alicyclic isocyanates, echaphazela ukuqina, ukuchasana kwemozulu kunye nokumelana nokutyheli kwewpua.IiDiols ikakhulu ziquka i-polyether diols kunye ne-polyester diols, ezichaphazela amandla okuqina, ukuthamba, ukuxhathisa ubushushu kunye nokumelana ne-hydrolysis ye-wpua.
I-NCO iqela kwi-polyisocyanate isabela kunye neqela le-hydroxyl ye-diol ukwenza i-oligomer kunye namaqela e-isocyanate kuzo zombini iziphelo.2. I-2,2-dihydroxymethylpropionic acid (i-DMPA) isetyenziswe njenge-diol ukwazisa amaqela e-hydrophilic kwi-oligomer, kunye ne-1,4-butanediol (BDO) yongezwa kwi-chain extension chain;3. I-Hydroxyethyl acrylate (HEA) yayisetyenziselwa ukwazisa amaqela asebenzayo ezithombe aqulethe iibhondi eziphindwe kabini ezingaxutywanga zokunyanga kwe-UV.Emva kokuba kugqityiwe ukusabela kwamanyathelo amathathu, i-triethanolamine (i-teoa) yongezwa ukuze i-neutralization reaction, kwaye ekugqibeleni amanzi adityaniswe ukuze afake i-lotion.
Abanye abaphengululi baye benza i-uv-wpua ngokusebenza okugqwesileyo ngokusebenzisa imathiriyeli ekrwada yokwenziwa efana nePolyhexylene glycol, isophorone diisocyanate, iPETA, kunye ne-dimethylbutyric acid (DMBA).Iintlobo ezintathu ze-wpua zadityaniswa ukusuka kwipolyacrylate elungisiweyo kunye neqela le-carboxyl kwikhonkco elisecaleni, i-polyether polyol, i-isophorone diisocyanate kunye ne-hydroxyethyl acrylate.Emva kophando olubanzi lovavanyo lomzimba kunye novavanyo lwesicelo, kucatshangelwa ukuba ukusebenza okubanzi kwe-polyether wpua kungcono.Ukusebenzisa i-toluene diisocyanate, i-polyhexanediol, i-2,2-dihydroxymethylpropionic acid kunye ne-hydroxyethyl methacrylate njengezinto ezibonakalayo, i-prepolymer yaqala ukwenziwa, emva koko i-triethylamine yongezwa njenge-agent engathathi hlangothi, kwaye amanzi asetyenziswa njenge-chain extender ukusabalalisa emanzini ukwenza i-wpua ezinzileyo.
