Amine Antioxidants, amine antioxidants yog siv rau inhibit thermal oxygen one ion thiab hnyav hlau ion thiab kev tiv thaiv cov nyhuv yog qhov tshwj xeeb. Nws qhov tsis zoo yog cov pa phem, raws li cov qauv tuaj yeem muab faib ntxiv ua:

Phenylas chav kawm: xws li anti-a lossis antioxidant j lossis rog yog vim li cas lom zem, vim yog cov tshuaj tiv thaiv kab mob ua si, hom tshuaj antioxidant no tau tsis tshua muaj teb chaws txawv teb chaws.

Ketamine Antioxidant: tuaj yeem muab cov roj hmab zoo heev thiab cov pa oxygen ua kom zoo, tab sis tsis tshua muaj kev ua tau zoo rau cov kab ke catalalytic ntawm cov hlau ions thiab ozone kev ua haujlwm qub. Los tiv thaiv tus neeg sawv cev RD. Anti-laus tus neeg sawv cev aw tsis tsuas yog muaj nuj nqi ntawm antioxidant, thiab feem ntau siv ua anti-tsw oxygen tus neeg sawv cev.

Diphenylamine derivatives: Cov antioxidants insibitess zoo li cas los yog tsawg dua li antioxidant, lawv muaj sib npaug rau antioxidant DD. Tab sis kev tiv thaiv tawm tsam kev qaug zog kev laus yog qis dua cov tom kawg.

Cov txiv ntoo ntawm p-phenylenediamine: cov antioxidants yog chav kawm ntawm antioxidants dav siv hauv kev lag luam roj hmab tam sim no. Lawv tuaj yeem cuam tshuam ozone kev laus, qaug zog laus, thermal oxygen asing thiab hlau ion-cat-cat-catalyzed oxidation ntawm cov khoom lag luam roj hmab. Dialkyl p-phenylenediamine (xws li oop788). Cov tshuaj no muaj tshwj xeeb los tiv thaiv zone onezone kev laus, tshwj xeeb tshaj yog cov kev ua yeeb yam tsis muaj paraffin, thiab kev cuam tshuam zoo ntawm cov pa thermal kev niaj hnub. Txawm li cas los xij, lawv muaj ib qho kev nyiam los txhawb cov scorching.

Kev siv cov tshuaj no nrog Alkyl Aryl p-phenylenediamine tuaj yeem muab kev tiv thaiv zoo rau cov ntsiab lus tsis zoo Ozone kev laus. Qhov tseeb, dialkyl-p-phenylenediamine ib txwm siv hauv kev sib xyaw nrog alkyl-aryl-p-phenylenediamine. Alkyl aryl p-phenylenediamine xws li UOP588, 6pps. Cov tshuaj xws li muaj kev tiv thaiv kev tiv thaiv tsis sib luag. Thaum siv nrog paraffin ciab, lawv tseem qhia tau tias muaj kev tiv thaiv zoo tshaj plaws ozone kev laus thiab feem ntau tsis muaj qhov teeb meem ntawm kev txau Frost. Cov khoom siv ntau yam, 4010NA, tseem siv dav.

6ddp yog ib qho siv tau antioxidant hauv pawg no. Cov laj thawj rau qhov no yog tias nws tsis ua rau dermatitis, nws muaj tsawg dua kev nyab xeeb piv rau lwm tus kab mob alkylat, nws tsis tshua muaj ntxhiab piv rau lwm yam alkyl aryl Thiab Dialkyl p-phenylenediamine, nws yog ib qho zoo heev rau SBR, thiab nws qhia tau tias cov khoom ntawm antioxidant. Thaum cov neeg hloov chaw yog tag nrho cov aryl, nws yog hu ua p-phenylenediamine. Piv nrog alkyl aryl p-phenylenediamine, tus nqi yog tsawg, tab sis vim tias nws qeeb tsiv teb tsaws, cov tshuaj no muaj cov tshuaj tiv thaiv zoo thiab ua tau zoo antioxidants. Lawv qhov tsis zoo yog tias lawv yooj yim txau tshuaj yej hauv roj hmab nrog cov solubility tsis muaj txiaj ntsig, tab sis nws muaj txiaj ntsig zoo hauv CR Nws tuaj yeem tsim kev tiv thaiv zoo heev. Thiab nws tsis tsim cov teeb meem ntawm kev txhawb nqa scorching.

Phenolic Antioxidants

Hom tshuaj tua kab mob no feem ntau yog siv los ua tshuaj tua kab mob, cov neeg muaj qee tus kuj muaj lub luag haujlwm ntawm passive ntawm hlau ions. Tab sis cov nyhuv tiv thaiv tsis zoo li cov amine antioxidant, lub ntsiab kom zoo dua ntawm hom antioxidant no yog cov kuab paug, haum rau cov khoom siv roj hmab.

Hindered Phenol: Hom tshuaj antioxidant no yog qhov tsis muaj zog ntawm cov tshuaj yeeb dej caw thiab cov yeeb tshuaj muaj cov nyhuv nruab nrab. Anti-Aging Tus Neeg Sawv Cev 264 tuaj yeem siv hauv cov khoom lag luam-cov khoom noj.

Tab kaum phom: feem ntau siv ntau yam ntawm 2246 thiab 2246S, kev tiv thaiv kev tiv thaiv thiab tsis muaj kev tiv thaiv zoo rau cov khoom lag luam daim ntaub ntawv tais diav, tab sis kuj tau siv nyob rau hauv cov khoom yas Cov.

Ntau hom phenols, feem ntau yog hais txog qhov kev txiav txim siab ntawm p-phenylenediamine, xws li ib qho ntawm cov tshuaj viscosity ntawm cov roj hmab cov duab roj hmab thiab cov nplaum, tab sis kuj NRBR Br Stabilizer.

Organic Sulfide hom antioxidant

Hom tshuaj tua kab mob no yog siv dav ua cov stabilizer rau polyolefin plastics raws li cov med caterroxide rhuav tshem cov antioxidant. Ntau cov ntawv thov hauv cov roj hmab yog dithiocarbamates thiab thiol-raws benzimidazoles. Daim ntawv thov tam sim no ntawm ib qho ntxiv yog Dibutyl dithiocarbamate zinc. Cov tshuaj no feem ntau siv nyob rau hauv kev tsim cov roj hmab roj hmab tutililizer. Lwm qhov yog Dibutylithiocarbamic acid nickel (antioxidant NBC), tuaj yeem txhim kho kev tiv thaiv nBr, cr, sbr zoo li qub ozone aging. Tab sis rau lawv pab kang oxidation nyhuv.

Thiol raws benzimidazole

Xws li antioxidants MB, MBZ, tseem yog ib qho ntawm cov antioxidant hauv roj hmab, lawv muaj cov nyhuv tiv thaiv nr, sbr, br, nbr. Thiab tau inhibited lub cathabal oxidation ntawm tooj liab ions, tej tshuaj no thiab qee cov tshuaj tua kab mob nquag siv thiab feem ntau ua cov kev cuam tshuam synoxidant. Hom tshuaj tiv thaiv kab mob antioxidant feem ntau siv hauv cov khoom lag luam xim.

Tsis-migratory antioxidant

Qhov twg cov roj hmab hauv kev tiv thaiv ntev ntev ntawm cov tshuaj tiv thaiv kab mob antioxidants, qee tus kuj hu ua cov tshuaj tiv thaiv kab mob lossis tshuaj tiv thaiv kab mob antioxidants. Piv nrog cov antioxidant feem ntau yog qhov nyuaj rau kev rho tawm, nyuaj rau kev tsiv teb tsaws, yog li ntawd antioxidant nyob rau hauv cov roj hmab los tiv thaiv cov nyhuv tiv thaiv ntev ntawm plaub txoj hauv kev:

1, Nce cov molecular qhov hnyav ntawm antioxidant.
2, kev ua cov tshuaj tiv thaiv kab mob thiab cov roj hmab siv tshuaj roj hmab.
3, antioxidant yog grafted rau cov roj hmab ua ntej ua.
4, nyob rau hauv kev tsim khoom, yog li ntawd Monomer nrog kev tiv thaiv muaj nuj nqi thiab roj hmab monomer copolymerization.
Lub antioxidant nyob rau hauv tom kawg peb txoj kev, qee zaum tseem hu ua reactive antioxidant lossis polymer sib koom tes antioxidant.
