Amine antioxidants, amine antioxidants amagwiritsidwa ntchito makamaka kuletsa kukalamba kwa okosijeni, ukalamba wa ozoni, ukalamba wotopa ndi heavy metal ion catalytic oxidation, chitetezo ndi chapadera.Kuipa kwake ndikuipitsa, malinga ndi kapangidwe kake kangagawikenso kukhala:

Phenyl naphthylamine class: monga anti-A kapena anti-A, antioxidant J kapena D, PBNA ndi antioxidant yakale kwambiri, yomwe imagwiritsidwa ntchito kwambiri kuletsa ukalamba wa okosijeni wamafuta ndi ukalamba wotopa, chifukwa cha kawopsedwe, mtundu uwu wa antioxidant sunagwiritsidwe ntchito kawirikawiri. maiko akunja.

Ketamine antioxidant: imatha kupatsa mphira wa diene kutentha kwabwino kwambiri komanso kukalamba kwa okosijeni, nthawi zina kuti apereke kukana kwabwino kwa kusweka kwa flexural, koma kawirikawiri kuletsa makutidwe ndi okosijeni othandizira a ayoni achitsulo ndi ntchito yokalamba ya ozoni.Anti-aging agent RD.Anti-aging agent AW sikuti imakhala ndi ntchito ya antioxidant, ndipo imagwiritsidwa ntchito ngati anti-odor oxygen agent.

Zochokera ku diphenylamine: Ma antioxidants awa amalepheretsa kukalamba kwa okosijeni wamafuta wofanana kapena wocheperapo kuposa dihydroquinoline polima, akagwiritsidwa ntchito ngati antioxidant, amafanana ndi antioxidant DD.koma chitetezo ku kutopa ukalamba n'chochepa kuposa chakumapeto.

Zochokera ku p-phenylenediamine: Ma antioxidants awa ndi gulu la ma antioxidants omwe amagwiritsidwa ntchito kwambiri pamakampani opanga mphira pakadali pano.Amatha kuletsa ukalamba wa ozoni, ukalamba wotopa, ukalamba wotentha wa okosijeni ndi chitsulo cha ion-catalyzed oxidation ya zinthu za rabara.Dialkyl p-phenylenediamine (monga UOP788).Zinthuzi zimakhala ndi kukalamba kwapadera kwa ozoni, makamaka kukalamba kosasunthika kwa ozoni popanda parafini, komanso kuletsa kukalamba kwa mpweya wabwino.Komabe, iwo ali ndi chizolowezi cholimbikitsa kutentha.

Kugwiritsa ntchito zinthu izi ndi alkyl aryl p-phenylenediamine kungapereke chitetezo chabwino ku ukalamba wosasunthika wa ozoni.Ndipotu, dialkyl-p-phenylenediamine nthawi zonse amagwiritsidwa ntchito limodzi ndi alkyl-aryl-p-phenylenediamine.Alkyl aryl p-phenylenediamine monga UOP588, 6PPD.zinthu zotere zili ndi chitetezo chapadera ku ukalamba wamphamvu wa ozoni.Akagwiritsidwa ntchito ndi sera ya parafini, amasonyezanso chitetezo chapadera ku ukalamba wosasunthika wa ozoni ndipo nthawi zambiri sakhala ndi vuto la kupopera mbewu mankhwalawa chisanu.Mitundu yakale kwambiri, 4010NA, imagwiritsidwabe ntchito kwambiri.

6DDP ndi antioxidant yomwe imagwiritsidwa ntchito kwambiri m'gululi.Zifukwa za izi ndikuti sizimayambitsa dermatitis, zimakhala ndi zotsatira zochepa pa chitetezo cha ndondomeko poyerekeza ndi alkyl aryl p-phenylenediamine ndi dialkyl p-phenylenediamine, zimakhala ndi chizolowezi chochepa cholimbikitsa kutentha, zimakhala zochepa kwambiri poyerekeza ndi alkyl aryl ena. ndi dialkyl p-phenylenediamine, ndi stabilizer yabwino kwa SBR, ndipo imasonyeza katundu wa antioxidant.Pamene zolowa m'malo onse aryl, amatchedwa p-phenylenediamine.Poyerekeza ndi alkyl aryl p-phenylenediamine, mtengo wake ndi wochepa, koma ntchito yotsutsa ozonation imakhalanso yotsika, ndipo chifukwa cha kusuntha kwake pang'onopang'ono, zinthuzi zimakhala ndi mphamvu zokhazikika komanso zimakhala ndi antioxidants.Kuipa kwawo ndikuti ndi osavuta kupopera kirimu mu rabala ndi kusungunuka kochepa, koma ndi kothandiza kwambiri mu CR kungapangitse chitetezo chabwino kwambiri.Ndipo sizimabweretsa vuto lolimbikitsa kutentha.

Phenolic antioxidants

Mtundu uwu wa antioxidant umagwiritsidwa ntchito makamaka ngati antioxidant, mitundu yamunthu imakhalanso ndi gawo la ayoni zitsulo.Koma zotetezera sizili bwino monga amine antioxidant, ubwino waukulu wa mtundu uwu wa antioxidant ndi wosaipitsa, woyenera mankhwala a rabara amtundu wowala.

Zolepheretsa phenol: mtundu uwu wa antioxidant umagwiritsidwa ntchito kwambiri ndi antioxidant 264, SP ndi ma antioxidants ena olemera kwambiri a maselo, poyerekeza ndi kusakhazikika kwa zinthu zotere ndipo chifukwa chake kusakhazikika bwino, koma zinthuzi zimakhala ndi zoteteza zapakatikati.Anti-aging 264 angagwiritsidwe ntchito pazakudya zamagulu.

Ma bisphenols omwe amalepheretsa: mitundu yomwe imagwiritsidwa ntchito kwambiri 2246 ndi 2246S, ntchito yoteteza komanso yosaipitsa zinthu izi ndi yabwino kuposa ma phenol omwe amalepheretsa, koma mtengo wake ndi wokwera, zinthuzi zimatha kupereka chitetezo chogwira ntchito pakupanga siponji ya mphira, komanso kugwiritsidwa ntchito muzinthu za latex. .

Mipikisano phenols, makamaka amatanthauza zotumphukira za p-phenylenediamine, monga 2,5-di-tert-amylhydroquinone ndi mmodzi wa iwo, zinthu zimenezi makamaka ntchito kusunga mamasukidwe akayendedwe mafilimu unvulcanized labala ndi zomatira, komanso NBR BR. stabilizer.

Organic sulfide mtundu wa antioxidant

Mtundu uwu wa antioxidant umagwiritsidwa ntchito kwambiri ngati stabilizer ya polyolefin mapulasitiki ngati hydroperoxide kuwononga antioxidant.Ntchito zambiri mu rabala ndi dithiocarbamates ndi benzimidazoles yochokera ku thiol.Kugwiritsa ntchito kwaposachedwa kwambiri ndi dibutyl dithiocarbamate zinc.Izi zimagwiritsidwa ntchito popanga butyl rabara stabilizer.Wina ndi dibutyldithiocarbamic asidi faifi tambala (antioxidant NBC), akhoza patsogolo chitetezo cha NBR, CR, SBR malo amodzi ozoni ukalamba.Koma kwa NR imathandizira kakulidwe ka okosijeni.

Thiol-based benzimidazole

Monga ma antioxidants MB, MBZ, ndi amodzi mwa antioxidants omwe amagwiritsidwa ntchito kwambiri mu rabara, amakhala ndi chitetezo chochepa pa NR, SBR, BR, NBR.Ndipo aletsa kutsekemera kwa ma ayoni amkuwa, zinthu zotere komanso ma antioxidants omwe amagwiritsidwa ntchito kwambiri ndipo nthawi zambiri amatulutsa zotsatira zogwirizana.Kuwonongeka kwamtundu uwu wa antioxidant nthawi zambiri kumagwiritsidwa ntchito pazinthu zowala.

Antioxidant yosamuka

Kumene mphira muchitetezo chosatha cha antioxidants, chotchedwa non-migrating antioxidants, ena amatchedwanso osatulutsa antioxidants kapena antioxidants osatha.Poyerekeza ndi antioxidant ambiri ndi zovuta kuchotsa, zovuta kusewera ndi zovuta kusamuka, kotero kuti antioxidant mu mphira kusewera okhalitsa zoteteza zotsatira za njira zinayi zotsatirazi:

1, Wonjezerani kulemera kwa maselo a antioxidant.
2, kukonza ma antioxidants ndi mphira wolumikizana ndi mankhwala.
3, Antioxidant imamezetsanidwa parabala musanakonze.
4, mu kupanga ndondomeko, kuti monoma ndi ntchito zoteteza ndi mphira monoma copolymerization.
Antioxidant mu njira zitatu zomalizazi, nthawi zina zimadziwikanso kuti reactive antioxidant kapena polima bonding antioxidant.
