I-Waterborne Polyurethane uhlobo olusha lohlelo lwe-polyurethane olusebenzisa amanzi esikhundleni se-organic solvents njenge-medium ehlakazayo. Inezinzuzo zokungcoliswa, ukuphepha kanye nokuthembela, izakhiwo ezinhle kakhulu zemishini, ukuhambisana okuhle, kanye nokuguqulwa okulula.
Kodwa-ke, izinto ze-polyurethane nazo zihlushwa ukumelana kwamanzi ampofu, ukumelana nokushisa, kanye nokumelana nokuqina kwe-solvent ngenxa yokuntuleka kwezibopho ezizinzile ezizinzile.
Ngakho-ke, kuyadingeka ukuthuthukisa nokwandisa izakhiwo ezihlukene zesicelo ze-polyurethane ngokwazisa ama-monomers afana ne-organic fluorosilicone, i-epoxy resin, kanye nama-nanomatadium.
Phakathi kwazo, izinto ze-polyurethane eziguquliwe zase-polyurethane zingathuthukisa kakhulu izakhiwo zazo zemishini, ukugqoka ukugqokwa, nokuqina okushisayo. Izindlela zokuguqulwa zifaka indlela yokuxhumana ye-composite, indlela ye-in-situ polymerization, indlela eshayayo, njll.
Nano silica
I-SIO2 inesakhiwo senethiwekhi enezici ezintathu, enenombolo enkulu yamaqembu e-hydroxyl asebenzayo ebusweni bayo. Kungathuthukisa izakhiwo eziphelele zenhlanganisela ngemuva kokuhlanganiswa ne-polyurethane ngesibopho esingejwayelekile kanye ne-van der Waals Force, njengokuphikiswa okuphakeme, okuphansi okuphansi, ukumelana nokuguga, njll. Guo et al. Synthesised Nano-Sio2 Modified Polyurethane Isebenzisa indlela ye-In-Situ Polymerization. Lapho okuqukethwe kwe-SIO2 kucishe kube ngu-2% (WT, ingxenye enkulu, okufanayo ngezansi), i-Shear Viscosity kanye namandla we-peel of a adhesive athuthukiswa ngokuyisisekelo. Uma kuqhathaniswa ne-polyurethane ehlanzekile, ukumelana okuphezulu okuphezulu kanye namandla ashukumisayo nawo akhuphuke kancane.
Nano zinc oxide
I-Nano ZNO inamandla amakhulu emishini, izakhiwo ezinhle ze-antibacterial ne-bacteriostatic, kanye nekhono elinamandla lokudonsa imisebe ye-infrared kanye nokuvikelwa okuhle kwe-UV, okwenza kube lula ukwenza izinto ngezinto ezikhethekile. Awad et al. wasebenzisa indlela ye-nano positron yokufaka ama-zno filler ku-polyurethane. Ucwaningo luthole ukuthi kukhona ukuxhumana okubonakalayo phakathi kwama-nanoparticles ne-polyurethane. Ukwandisa okuqukethwe kweNano ZNO kusuka ku-0 kuye ku-5% kwandise izinga lokushisa le-Glass Transsure (TG) yePolyurethane, eyathuthukisa ukuqina kwayo okushisayo.
Nano calcium carbonate
Ukuxhumana okunamandla phakathi kweNano Caco3 ne-matrix kuthuthukisa kakhulu amandla ashubile wezinto ze-polyurethane. Gao et al. Okokuqala ukuguqulwa kwe-nano3 nge-oleic acid, bese kulungiswa i-polyurethane / caco3 ngokusebenzisa i-in-situ polymerization. Ukuhlolwa kwe-infrared (FT-IR) kukhombisa ukuthi ama-nanoparticles ayehlakazeka ngendlela efanayo kwi-matrix. Ngokusho kokuhlolwa kokusebenza kwemishini, kwatholakala ukuthi i-polyurethane eguqulwe ngama-nanoparticles inamandla aphezulu aphezulu kune-polyurethane ehlanzekile.
Uhlobo
I-Graphene (g) iyisakhiwo esibekiwe esihlanganiswe yi-SP2 hybrid ama-orbitols, esibonisa amandla amahle kakhulu, ukusebenza okushisayo, nokuqina. Inamandla aphezulu, ubulukhuni obuhle, futhi kulula ukugoba. I-Wu et al. I-Synthesised AG / G / PE Nanocomos, futhi ngokwanda kokuqukethwe kwe-AG / G, ukuqina okushisayo kanye ne-hydrophobicity yezinto ezihlanganisiwe zaqhubeka nokuthuthuka, futhi ukusebenza kwe-antibacterial nakho kukhuphuke ngokufanele.
I-Carbon Nanotubes
I-Carbon Nanotubes (CNTs) yi-nanomatale yobukhulu obuhlukile ye-tubulale Ngokusebenzisa amandla ayo aphezulu, ama-accoughtivity, kanye ne-polyurethane composite izakhiwo, ukuqina okushisayo, izakhiwo zemishini kanye nokuvuselelwa kwezinto ezibonakalayo kungathuthukiswa. I-Wu et al. Ukwethulwa ama-CNTs ngokusebenzisa i-In-Situ Polymerization ukulawula ukukhula nokwakheka kwezinhlayiya ze-emulsion, okwenza ama-CNT ahlakazeke ngokufana ePolyurethane Matrix. Ngokuqukethwe okukhulayo kwama-CNTs, amandla ashukumisayo wezinto ezihlanganisiwe athuthuke kakhulu.
Inkampani yethu inikeza i-silica esezingeni eliphakeme,Ama-Anti-Hydrolysis Agents (Agents Crossinking, Carbodiimide), Ama-UV atholakalayo, njll., okuthuthukisa kakhulu ukusebenza kwe-polyurethane.
