I-amine antioxidants, i-amine antioxidants isetyenziselwa ukuthintela ukuguga kwe-oksijini eshushu, ukuguga kwe-ozone, ukudinwa ukuguga kunye ne-ion metal catalytic oxidation enzima, umphumo wokukhusela ukhethekile.Ukungalungi kwayo kungcoliseko, ngokwesakhiwo sinokwahlulwa kwakhona sibe:

Iklasi ye-Phenyl naphthylamine: njenge-anti-A okanye i-anti-A, i-antioxidant J okanye i-D, i-PBNA yeyona nto indala ye-antioxidant, isetyenziselwa ukuthintela ukuguga kwe-oksijeni ye-thermal kunye nokuguga, ngenxa yezizathu ze-toxicity, olu hlobo lwe-antioxidant alufane lusetyenziswe kwi-antioxidant. amazwe angaphandle.

I-Ketamine antioxidant: inokunika irabha ye-diene ubushushu obuhle kakhulu kunye nokusebenza kwe-oksijini yokuguga, kwezinye iimeko ukunika ukuxhathisa okulungileyo ekusebenzeni kokuqhekeka kwe-flexural, kodwa kunqabile ukuba kuthintele i-oxidation ye-catalytic ye-ion zetsimbi kunye nomsebenzi wokuguga we-ozone.Anti-aging agent RD.I-agent ye-anti-aging AW ayinayo kuphela umsebenzi we-antioxidant, kwaye isetyenziswa rhoqo njenge-agent ye-oxygen anti-odor.

I-Diphenylamine derivatives: Ezi antioxidants zivimbela ukusebenza kwe-oksijini eshushu eguga ngokulingana okanye ngaphantsi kwe-polymer ye-dihydroquinoline, xa isetyenziswe njenge-antioxidant, ilingana ne-antioxidant DD.kodwa ukhuselo lokudinwa ukuguga luphantsi kunolo lwamva.

I-Derivatives ye-p-phenylenediamine: Ezi antioxidants ziyiklasi ye-antioxidants esetyenziswa ngokubanzi kwishishini lerabha ngoku.Bangakwazi ukuthintela ukuguga kwe-ozone, ukukhathala ukuguga, ukuguga kwe-oxygen ye-thermal kunye ne-metal ion-catalyzed oxidation yeemveliso zerabha.I-Dialkyl p-phenylenediamine (efana ne-UOP788).Ezi zinto zine-ozone ekhethekileyo yokuguga, ngokukodwa ukusebenza kwe-ozone ye-static ngaphandle kweparafini, kunye nokuthintela okulungileyo kwefuthe lokuguga kwe-oksijini ye-thermal.Nangona kunjalo, banotyekelo lokukhuthaza ukutshisa.

Ukusetyenziswa kwezi zinto kunye ne-alkyl aryl p-phenylenediamine inokubonelela ngokhuseleko olufanelekileyo malunga nokuguga okuguquguqukayo kwe-ozone.Enyanisweni, i-dialkyl-p-phenylenediamine isoloko isetyenziswa ngokudibanisa ne-alkyl-aryl-p-phenylenediamine.Alkyl aryl p-phenylenediamine ezifana UOP588, 6PPD.ezo zinto zinokhuselo olubalaseleyo ngokuchasene nokuguga okuguquguqukayo kwe-ozone.xa zisetyenziswa kunye neparafini wax, zikwabonisa ukhuseleko olubalaseleyo ngokuchasene nokuguga kwe-ozone kwaye ngokuqhelekileyo abanayo ingxaki yokutshiza iqabaka.Olona didi lokuqala, i-4010NA, lusasetyenziswa ngokubanzi.

I-6DDP ikwayinto esetyenziswa ngokuqhelekileyo kwi-antioxidant kolu didi.Izizathu zale nto kukuba ayibangeli i-dermatitis, inempembelelo encinci ekukhuselekeni kwenkqubo xa kuthelekiswa nezinye i-alkyl aryl p-phenylenediamine kunye ne-dialkyl p-phenylenediamine, inokuthambekela okuncinci ukukhuthaza ukutshisa, iyancipha kancinci xa kuthelekiswa nezinye i-alkyl aryl. kunye ne-dialkyl p-phenylenediamine, sisizinzi esihle kakhulu se-SBR, kwaye ibonisa iipropati ze-antioxidant.Xa izinto ezibambeleyo ziyi-aryl yonke, ibizwa ngokuba yi-p-phenylenediamine.Xa kuthelekiswa ne-alkyl aryl p-phenylenediamine, ixabiso liphantsi, kodwa umsebenzi wokuchasana ne-ozonation uphantsi, kwaye ngenxa yezinga lokuhamba kancinci, ezi zinto zinokuqina okulungileyo kwaye zisebenza ngokufanelekileyo kwi-antioxidants.Ukungalungi kwabo kukuba kulula ukutshiza ukhilimu kwirubha ene-solubility ephantsi, kodwa iluncedo kakhulu kwi-CR inokuvelisa ukhuseleko oluhle kakhulu.Kwaye ayivelisi ingxaki yokukhuthaza ukutshisa.

Phenolic antioxidants

Olu hlobo lwe-antioxidant lusetyenziswa ikakhulu njenge-antioxidant, iintlobo zomntu ngamnye zinendima yokudlula i-ion zetsimbi.Kodwa umphumo wokukhusela awulungile njenge-antioxidant ye-amine, inzuzo ephambili yolu hlobo lwe-antioxidant ayingcolisi, ifanelekile kwiimveliso zerabha ezikhanyayo.

I-phenol ethintelweyo: olu hlobo lwe-antioxidant lusetyenziswa ngokubanzi i-antioxidant ye-264, i-SP kunye nezinye ii-antioxidants ezinobunzima be-molecular, xa kuthelekiswa nokuguquguquka kwezinto ezinjalo kwaye ngenxa yoko ukuqina okungahambi kakuhle, kodwa ezi zinto zinefuthe eliphakathi lokukhusela.I-agent ye-anti-aging 264 ingasetyenziswa kwiimveliso zebakala lokutya.

I-bisphenols ethintelweyo: iintlobo ezisetyenziswa ngokuqhelekileyo ze-2246 kunye ne-2246S, umsebenzi wokukhusela kunye nokungangcoliseki kwezi zinto kungcono kune-phenols ezithintelweyo, kodwa ixabiso liphezulu, ezi zinto zinokubonelela ngokhuseleko olusebenzayo lweemveliso ze-sponge zerabha, kodwa zikwasetyenziswa kwiimveliso ze-latex. .

I-Multi-phenols, ikakhulu ibhekisa kwi-derivatives ye-p-phenylenediamine, efana ne-2,5-di-tert-amylhydroquinone yenye yazo, ezi zinto zisetyenziselwa ukugcina i-viscosity yeefilimu zerabha ezingavulwanga kunye ne-adhesives, kodwa kwakhona NBR BR ukuzinzisa.

Organic sulfide uhlobo antioxidant

Olu hlobo lwe-antioxidant lusetyenziswa ngokubanzi njenge-stabilizer yeeplastiki ze-polyolefin njenge-hydroperoxide etshabalalisa i-antioxidant.Usetyenziso olungakumbi kwirabha yi-dithiocarbamates kunye ne-thiol-based benzimidazoles.Ukusetyenziswa kwangoku kokungaphezulu yi-dibutyl dithiocarbamate zinc.Le nto isetyenziswa ngokuqhelekileyo kwimveliso ye-butyl rubber stabilizer.Enye i-dibutyldithiocarbamic acid nickel (i-antioxidant NBC), inokuphucula ukukhuselwa kwe-NBR, CR, SBR static ozone ukuguga.Kodwa kwi-NR inceda impembelelo ye-oxidation.

I-benzimidazole esekelwe kwi-Thiol

Njenge-antioxidants MB, i-MBZ, nayo enye ye-antioxidants esetyenziswa ngokuqhelekileyo kwi-rubber, inefuthe elikhuselayo elikhuselayo kwi-NR, SBR, BR, NBR.Kwaye ithintele i-oxidation ye-catalytic ye-ion zethusi, izinto ezinjalo kunye nezinye ezisetyenziswa ngokuqhelekileyo i-antioxidants kwaye zihlala zivelisa iziphumo ze-synergistic.Olu hlobo longcoliseko lwe-antioxidant luhlala lusetyenziswa kwiimveliso ezinombala okhanyayo.

I-antioxidant engafudukiyo

Apho irabha kwisiphumo sokukhusela esihlala sihleli se-antioxidants, ebizwa ngokuba yi-antioxidant engafudukiyo, ezinye zikwabizwa ngokuba ngama-antioxidants angenakucatshulwa okanye ama-antioxidants aqhubekayo.Xa kuthelekiswa ne-antioxidant ngokubanzi kunzima ukuyikhupha, kunzima ukuyidlala kwaye kunzima ukufuduka, ukuze i-antioxidant kwirabha idlale umphumo okhuselekileyo wokukhusela kwezi ndlela zine zilandelayo:

1, Yongeza ubunzima bemolekyuli ye-antioxidant.
2, ukusetyenzwa kwe-antioxidants kunye ne-rubber chemical bonding.
3, I-antioxidant imiliselwe kwirabha ngaphambi kokuba iqhubeke.
I-4, kwinkqubo yokuvelisa, ukwenzela ukuba i-monomer enomsebenzi wokukhusela kunye ne-rubber monomer copolymerization.
I-antioxidant kwezi ndlela zintathu zokugqibela, ngamanye amaxesha ikwabizwa ngokuba yi-antioxidant esebenzayo okanye i-polymer bonding antioxidant.
