O mea mataʻutia mo polyurethane elastomers e tele lava vaega e tolu, e taʻua o le oligomer polyols, polyisocyanates ma le faʻalauteleina o filifili (crosslinking agents).E le gata i lea, o nisi taimi ina ia faʻateleina ai le saoasaoa o le tali atu, faʻaleleia le gaioiga gaioiga ma le faʻatinoga o oloa, e tatau ona faʻaopoopo nisi o mea faʻapipiʻi.E naʻo mea faʻaaogaina i le gaosiga o nofoa polyurethane o loʻo faʻamatalaina auiliili i lalo.

Polyurethane elastomer oloa e lanu, ma o latou foliga matagofie e faalagolago i lanu.E lua ituaiga o lanu, vali faʻaletino ma pigments e le faʻaogaina.O le tele o vaila'au fa'aletino e fa'aaogaina i oloa polyurethane thermoplastic, mea teuteu ma fa'amatagofieina vaega tui ma vaega fa'asalalau.E masani ona lua auala e valivali ai oloa elastomer: o le tasi o le oloina o mea fesoasoani e pei o pigments ma oligomer polyols e fausia ai le paʻu lanu ava malosi, ona faʻafefiloi lea ma faʻafefiloi se aofaiga talafeagai o lanu paʻu tina ava malosi ma oligomer polyols tutusa, ona sosoo ai lea. vevela i latou.A maeʻa le faʻamaʻaina o le vai, e tali atu i vaega o le isocyanate e maua ai oloa, e pei o le thermoplastic polyurethane color granules ma mea faʻapipiʻi lanu;O le isi metotia o le oloina o mea faaopoopo e pei o pigments ma oligomer polyols poʻo plasticizers i le paʻu lanu poʻo le paʻu lanu, faʻamaʻaina e le vevela ma le gaogao, ma afifi mo le faʻaaogaina mulimuli.A fa'aoga, fa'aopoopo sina pa'u lanu la'ititi i totonu o le prepolymer, fa'aoso fa'atasi, ona fa'afo'i lea ma le so'o fa'alava e fa'alautele le filifili e lafo ai le oloa.O lenei metotia e masani ona faʻaaogaina i le MOCA vulcanization system, o le pigment content i totonu o le paʻu lanu e tusa ma le 10% -30%, ma o le aofaʻi faaopoopo o le paʻu lanu i le oloa e masani lava i lalo ole 0.1%.

O le polymer diol ma le diisocyanate ua faia i prepolymers, ua faʻafefiloi faʻatasi, tui i totonu o le paʻu pe a maeʻa le faʻafefeteina o le gaogao, tui i totonu o le paʻu ma faʻamalolo, ona faʻamaloloina lea e maua ai le oloa:

Muamua, faʻamama le mea faʻapipiʻi polyurethane elastomer i lalo o le faʻaitiitia o le mamafa i le 130 ℃, faʻaopopo le faʻamaʻi o le polyester mata (i le 60 ℃) i totonu o le vaʻa tali o loʻo i ai le TDI-100 tuʻufaʻatasia, ma faʻapipiʻi le prepolymer ma lava le faʻamalosi.Ole tali fa'atupu ole fa'atupu ole exothermic, ma e tatau ona maitauina e tatau ona pulea le vevela ole tali ile va ole 75 ℃ i le 82 ℃, ma e mafai ona faia le tali mo le 2 itula.Ona tu'u lea o le prepolymer fa'apipi'i i totonu o se ogaumu fa'amago gaogao i le 75°C, ma fa'amama i lalo o le masini mo le 2 itula a'o le'i fa'aogaina.

Ona faʻamafanafanaina lea o le prepolymer i le 100 ℃, ma faʻamama (vacuum degree -0.095mpa) e aveese ai le ea, fuaina le sui faʻafesoʻotaʻi MOCA, faʻamafanafana i se ogaumu eletise i le 115 ℃ e liusuavai, ma faʻaofuofu le limu ma se faʻamalolo talafeagai. sui e mua'i vevela (100℃).), o le degassed prepolymer ua fefiloi ma le MOCA liusuavai, o le vevela fefiloi o le 100 ℃, ma o le paluga o loʻo faʻavevesi tutusa.I totonu o le faʻamaʻi muamua, pe a le tafe pe pipii le paluga i le lima (gel-pei), tapuni le faʻamaʻi ma tuʻu i totonu o se vulcanizer mo le faʻaogaina o le vulcanization (tulaga faʻafefe: vulcanization vevela 120-130 ℃, vulcanization taimi, mo tele. ma elastomers mafiafia, o le taimi vulcanization e sili atu nai lo le 60min, mo elastomers laiti ma manifinifi, o le taimi vulcanization o le 20min), post-vulcanization togafitiga, tuʻu oloa faʻapipiʻi ma vulcanized i le 90-95 ℃ (i tulaga faʻapitoa, e mafai ona 100). ℃) Fa'aauau le vulcanize mo le 10 itula i totonu o le ogaumu, ona tu'u lea i le vevela o le potu mo le 7-10 aso e fa'amae'a ai le matua ma faia le oloa mae'a.
