Antioxydants ya amine, antioxydants ya amine ikoreshwa cyane cyane mukurinda gusaza ogisijeni yumuriro, gusaza ozone, gusaza umunaniro hamwe nicyuma kiremereye ion catalitike okiside, ingaruka zo kurinda ntizihagije.Ingaruka zayo ni umwanda, ukurikije imiterere irashobora kugabanywamo kabiri:

Icyiciro cya Phenyl naphthylamine: nka anti-A cyangwa anti-A, antioxydeant J cyangwa D, PBNA ni antioxydants ya kera cyane, ikoreshwa cyane cyane mu kubuza umwuka wa ogisijeni w’umuriro no gusaza, kubera impamvu z’uburozi, ubu bwoko bwa antioxydants bwakoreshejwe gake muri bihugu by'amahanga.

Antioxydants ya Ketamine: irashobora guha diene reberi ubushyuhe bwiza cyane hamwe nubusaza bwa ogisijeni, rimwe na rimwe kugirango itange imbaraga zo kurwanya imikorere ya flexural, ariko ni gake ibuza okiside ya catalitike ya ioni nicyuma cyo gusaza.Umukozi urwanya gusaza RD.Umuti urwanya gusaza AW ntabwo ufite imikorere ya antioxydeant gusa, kandi akenshi ikoreshwa nka anti-impumuro nziza ya ogisijeni.

Ibikomoka kuri Diphenylamine: Izi antioxydants zibuza imbaraga za ogisijeni yumuriro usaza cyangwa munsi ya polymer ya dihydroquinoline, iyo ikoreshejwe nka antioxydeant, ihwanye na antioxydeant DD.ariko kurinda gusaza umunaniro biri munsi yanyuma.

Ibikomoka kuri p-fenylenediamine: Izi antioxydants ni icyiciro cya antioxydants ikoreshwa cyane mu nganda za rubber muri iki gihe.Zishobora kubuza gusaza ozone, gusaza umunaniro, gusaza kwa ogisijeni yumuriro hamwe nicyuma cya ion-catisale okiside yibicuruzwa.Dialkyl p-phenylenediamine (nka UOP788).Ibi bintu bifite anti-static ya ozone gusaza, cyane cyane imikorere ya ozone ihagaze neza idafite paraffine, hamwe no kubuza neza ingaruka zo gusaza kwa ogisijeni.Ariko, bafite imyumvire yo guteza imbere gucana.

Gukoresha ibyo bintu hamwe na alkyl aryl p-phenylenediamine birashobora gutanga uburinzi bwiza bwo kwirinda gusaza kwa ozone.Mubyukuri, dialkyl-p-phenylenediamine ikoreshwa buri gihe hamwe na alkyl-aryl-p-phenylenediamine.Alkyl aryl p-phenylenediamine nka UOP588, 6PPD.ibintu nkibi bifite uburinzi buhebuje bwo kwirinda gusaza ya ozone.iyo ikoreshejwe ibishashara bya paraffin, irerekana kandi uburinzi budasanzwe bwo kwirinda gusaza kwa ozone kandi mubisanzwe ntabwo bafite ikibazo cyo gutera ubukonje.Ubwoko bwa mbere, 4010NA, buracyakoreshwa cyane.

6DDP nayo ni antioxydants ikoreshwa cyane muriki cyiciro.Impamvu zibitera nuko idatera dermatite, ntigira ingaruka nke kumutekano wibikorwa ugereranije nizindi alkyl aryl p-phenylenediamine na dialkyl p-phenylenediamine, ntabwo ifite ubushake buke bwo guteza inkongi, ntabwo ihindagurika ugereranije nizindi alkyl aryl na dialkyl p-phenylenediamine, ni stabilisateur nziza kuri SBR, kandi yerekana imiterere ya antioxydeant.Iyo insimburangingo zose ari aryl, yitwa p-phenylenediamine.Ugereranije na alkyl aryl p-phenylenediamine, igiciro ni gito, ariko igikorwa cyo kurwanya ozonation nacyo kiri hasi, kandi kubera umuvuduko wacyo wimuka, ibyo bintu bifite igihe kirekire kandi birwanya antioxydants.Ikibi cyabo nuko byoroshye gutera amavuta muri reberi hamwe nubushyuhe buke, ariko ni ingirakamaro cyane muri CR irashobora gutanga uburinzi bwiza cyane.Kandi ntabwo itanga ikibazo cyo guteza imbere gucana.

Antioxydants ya fenolike

Ubu bwoko bwa antioxydeant bukoreshwa cyane nka antioxydants, ubwoko butandukanye nabwo bufite uruhare rwa passivation ya ioni yicyuma.Ariko ingaruka zo gukingira ntabwo ari nziza nka antioxydeant amine, inyungu nyamukuru yubwoko bwa antioxydeant ntabwo ihumanya, ibereye ibicuruzwa bya rubber bifite ibara ryoroshye.

Fenol ikumirwa: ubu bwoko bwa antioxydeant bukoreshwa cyane antioxydants 264, SP hamwe nizindi antioxydants zifite uburemere buke cyane, ugereranije n’imihindagurikire y’ibintu bityo bikaba bitaramba, ariko ibyo bintu bigira ingaruka zo gukingira.Umuti urwanya gusaza 264 urashobora gukoreshwa mubicuruzwa byo mu rwego rwibiryo.

Bisfenol ikumirwa: ubwoko bukunze gukoreshwa bwa 2246 na 2246S, umurimo wo kurinda no kutanduza ibyo bintu nibyiza kuruta fenolisiyo zibangamiye, ariko igiciro kiri hejuru, ibyo bintu birashobora gutanga uburinzi bwiza kubicuruzwa bya reberi, ariko bikoreshwa no mubicuruzwa bya latex .

Multi-fenolike, ahanini yerekeza ku bikomoka kuri p-phenylenediamine, nka 2,5-di-tert-amylhydroquinone ni imwe muri zo, ibyo bintu bikoreshwa cyane cyane mu gukomeza ubwiza bwa firime ya reberi itavanze, hamwe na NBR BR stabilisateur.

Ubwoko bwa sulfide kama antioxydeant

Ubu bwoko bwa antioxydeant bukoreshwa cyane nka stabilisateur ya plastike ya polyolefin nka hydroperoxide yangiza antioxydeant.Porogaramu nyinshi muri reberi ni dithiocarbamates hamwe na benzimidazoles ishingiye kuri thiol.Kugeza ubu ikoreshwa rya byinshi ni dibutyl dithiocarbamate zinc.Iyi ngingo isanzwe ikoreshwa mugukora butyl rubber stabilisateur.Ikindi ni dibutyldithiocarbamic acide nikel (antioxidant NBC), irashobora kunoza uburinzi bwa NBR, CR, SBR static ozone gusaza.Ariko kuri NR ifasha kang okiside.

Thiol ishingiye kuri benzimidazole

Nka antioxydants MB, MBZ, nayo ni imwe muri antioxydants ikoreshwa cyane muri reberi, igira ingaruka zo gukingira kuri NR, SBR, BR, NBR.Kandi byabujije okiside ya catalitike ya ion z'umuringa, ibintu nkibi hamwe na antioxydants ikoreshwa cyane kandi akenshi bitanga ingaruka zifatika.Ubu bwoko bwumwanda wa antioxydeant bukoreshwa mubicuruzwa bifite amabara yoroheje.

Antioxydants itari iyimuka

Iyo reberi mu ngaruka zirambye zo kurinda antioxydants, bita antioxydants itimuka, zimwe nazo zitwa antioxydants idashobora gukururwa cyangwa antioxydants ikomeza.Ugereranije na antioxydants rusange muri rusange biragoye kuyikuramo, biragoye kuyikina kandi biragoye kwimuka, kugirango antioxydeant muri reberi ikore ingaruka zirambye zo kurinda uburyo bune bukurikira:

1 、 Ongera uburemere bwa molekile ya antioxydeant.
2, gutunganya antioxydants hamwe na rubber bihuza imiti.
3 ant Antioxydants yometse kuri reberi mbere yo kuyitunganya.
4, mubikorwa byo gukora, kugirango monomer ifite imikorere yo gukingira hamwe na rubber monomer copolymerisation.
Antioxydants muburyo butatu bwa nyuma, rimwe na rimwe izwi kandi nka antioxydeant reaction cyangwa polymer ihuza antioxydeant.
