ʻO nā antioxidants amine, nā amine antioxidants i hoʻohana nui ʻia e kāohi i ka ʻelemakule o ka oxygen thermal, ka ʻelemakule ozone, ka luhi luhi a me ke kaumaha metala ion catalytic oxidation, ʻokoʻa ka hopena pale.ʻO kona hemahema ka pollution, e like me ke kūkulu ʻana hiki ke hoʻokaʻawale hou ʻia i:

Phenyl naphthylamine papa: e like me ka anti-A a i ʻole anti-A, antioxidant J a i ʻole D, ʻo PBNA ka antioxidant kahiko loa, hoʻohana nui ʻia e pale i ka ʻelemakule o ka oxygen a me ka luhi luhi, ma muli o nā kumu ʻawaʻawa, ʻaʻole i hoʻohana pinepine ʻia kēia ʻano antioxidant. ʻāina ʻē.

Ketamine antioxidant: hiki ke hāʻawi i ka diene rubber maikaʻi loa i ka wela a me ka oxygen elemakule hana, i kekahi mau mea e hāʻawi maikaʻi i ke kūpaʻa ʻana i ka hana flexural cracking, akā ʻaʻole hiki ke pale i ka catalytic oxidation o nā ion metala a me ka hana ozone.Mea kūʻē i ka ʻelemakule RD.ʻAʻole wale ka hana o ka antioxidant anti-aging agent AW, a hoʻohana pinepine ʻia e like me ka anti-odor oxygen agent.

ʻO nā derivatives Diphenylamine: Ke kāohi nei kēia mau antioxidants i ka maikaʻi o ka wā kahiko o ka oxygen thermal e like a i ʻole ka liʻiliʻi ma mua o ka polymer dihydroquinoline, ke hoʻohana ʻia ma ke ʻano he antioxidant, ua like lākou me ka antioxidant DD.akā, ʻoi aku ka haʻahaʻa o ka pale ʻana i ka ʻelemakule luhi ma mua o ka hope.

Nā hua o ka p-phenylenediamine: ʻO kēia mau antioxidants he papa o nā antioxidants i hoʻohana nui ʻia i ka ʻoihana ʻōpala i kēia manawa.Hiki iā lākou ke pale i ka ʻelemakule ozone, ka ʻelemakule luhi, ka ʻelemakule o ka oxygen thermal a me ka hoʻoheheʻe ʻana i ka ion-catalyzed o nā huahana lāʻau.Dialkyl p-phenylenediamine (e like me UOP788).Loaʻa kēia mau mea i kahi ʻelemakule anti-static ozone kūikawā, ʻoi aku ka nui o ka hana kahiko ozone static me ka ʻole o ka paraffin, a me ka pale maikaʻi ʻana i ka hopena ʻelemakule wela.Eia nō naʻe, loaʻa iā lākou ka manaʻo e hoʻolaha i ka scorching.

ʻO ka hoʻohana ʻana i kēia mau mea me ka alkyl aryl p-phenylenediamine hiki ke hāʻawi i ka pale maikaʻi mai ka static dynamic ozone aging.ʻO kaʻoiaʻiʻo, hoʻohana mau ʻia ka dialkyl-p-phenylenediamine me ka alkyl-aryl-p-phenylenediamine.Alkyl aryl p-phenylenediamine e like me UOP588, 6PPD.ʻO ia mau mea he palekana maikaʻi loa mai ka dynamic ozone aging.ke hoʻohana ʻia me ka wax paraffin, hōʻike pū lākou i ka pale koʻikoʻi mai ka ʻelemakule ozone static a ʻaʻohe pilikia o ka hoʻoulu ʻana i ka hau.ʻO ka mea mua loa, 4010NA, hoʻohana nui ʻia.

ʻO 6DDP kekahi antioxidant maʻamau i hoʻohana ʻia i kēia ʻāpana.ʻO nā kumu o kēia, ʻaʻole ia e hoʻoulu i ka dermatitis, ʻoi aku ka liʻiliʻi o ka hopena i ka palekana o ke kaʻina hana i hoʻohālikelike ʻia me nā alkyl aryl p-phenylenediamine a me dialkyl p-phenylenediamine, ʻoi aku ka liʻiliʻi o ka hoʻoikaika ʻana i ka wela, ʻoi aku ka liʻiliʻi i ka hoʻohālikelike ʻia me nā alkyl aryl ʻē aʻe. a me ka dialkyl p-phenylenediamine, he mea hoʻopaʻa maikaʻi loa ia no SBR, a hōʻike ia i nā waiwai o kahi antioxidant.Inā he aril nā mea pani, ua kapa ʻia ʻo ia p-phenylenediamine.Ke hoʻohālikelike ʻia me ka alkyl aryl p-phenylenediamine, haʻahaʻa ke kumukūʻai, akā haʻahaʻa hoʻi ka hana anti-ozonation, a no ka lohi o ka neʻe ʻana, ua paʻa maikaʻi kēia mau mea a he mau antioxidants maikaʻi.ʻO kā lākou hemahema ʻo ia ka maʻalahi o ka pīpī ʻana i ka ʻaila i loko o ka lāʻau me ka haʻahaʻa haʻahaʻa, akā maikaʻi loa ia i ka CR hiki ke hana i ka pale maikaʻi loa.A ʻaʻole ia e hoʻopuka i ka pilikia o ka hoʻolaha ʻana i ka wela.

Phenolic antioxidants

Hoʻohana nui ʻia kēia ʻano antioxidant ma ke ʻano he antioxidant, ʻo nā ʻano like ʻole ke kuleana o ka passivation o nā ion metala.Akā ʻaʻole maikaʻi ka hopena pale e like me ka amine antioxidant, ʻo ka pōmaikaʻi nui o kēia ʻano antioxidant he polluting ʻole, kūpono i nā huahana kalapona māmā.

ʻO ka phenol i kāohi ʻia: hoʻohana nui ʻia kēia ʻano antioxidant antioxidant 264, SP a me nā antioxidants kaumaha molecular kiʻekiʻe, i hoʻohālikelike ʻia i ka volatility o ia mau mea a no laila maikaʻi ʻole ka lōʻihi, akā loaʻa kēia mau mea i ka hopena palekana.Hiki ke hoʻohana ʻia ka anti-aging agent 264 i nā huahana meaʻai.

ʻO nā bisphenols i pale ʻia: ʻoi aku ka maikaʻi o nā ʻano like ʻole o 2246 a me 2246S, ʻoi aku ka maikaʻi o ka hana pale a me ka pollution ʻole o kēia mau mea ma mua o nā phenols i kāohi ʻia, akā kiʻekiʻe ke kumukūʻai, hiki i kēia mau mea ke hāʻawi i ka palekana kūpono no nā huahana sponge, akā hoʻohana pū ʻia i nā huahana latex. .

ʻO nā multi-phenols, e pili ana i nā derivatives o ka p-phenylenediamine, e like me 2,5-di-tert-amylhydroquinone kekahi o lākou, ua hoʻohana nui ʻia kēia mau mea e mālama i ka viscosity o nā kiʻi ʻoniʻoni unvulcanized a me nā adhesives, akā pū kekahi NBR BR mea hoʻopaʻa.

He antioxidant ʻano sulfide organik

Hoʻohana nui ʻia kēia ʻano antioxidant ma ke ʻano he stabilizer no nā plastic polyolefin e like me ka hydroperoxide luku i ka antioxidant.ʻO nā mea hoʻohana hou aʻe i ka lāʻau lapaʻau he dithiocarbamate a me nā benzimidazoles-thiol.ʻO ka hoʻohana ʻana i kēia manawa o kahi mea ʻoi aku ka dibutyl dithiocarbamate zinc.Hoʻohana mau ʻia kēia mea i ka hana ʻana i ka butyl rubber stabilizer.ʻO kekahi ʻo dibutyldithiocarbamic acid nickel (antioxidant NBC), hiki ke hoʻomaikaʻi i ka pale o NBR, CR, SBR static ozone aging.Akā no ka NR kōkua i ka hopena oxidation.

ʻO ka benzimidazole ma muli o Thiol

E like me nā antioxidants MB, MBZ, ʻo ia kekahi o nā antioxidants maʻamau i hoʻohana ʻia i ka lāʻau lapaʻau, loaʻa iā lākou kahi hopena pale maʻalahi ma NR, SBR, BR, NBR.A ua pale i ka catalytic oxidation o nā iona keleawe, ia mau mea a me kekahi mau antioxidants i hoʻohana pinepine ʻia a hana pinepine i nā hopena synergistic.Hoʻohana pinepine ʻia kēia ʻano pollution antioxidant i nā huahana ʻulaʻula.

ʻO ka antioxidant non-migratory

Ma kahi o ka lāʻau lapaʻau i ka hopena pale mau o nā antioxidants, i kapa ʻia he non-migrating antioxidants, ua kapa ʻia kekahi mau antioxidants non-extractable a i ʻole nā ​​​​antioxidant mau loa.Ke hoʻohālikelike ʻia me ka antioxidant maʻamau he paʻakikī ke unuhi, paʻakikī ke pāʻani a paʻakikī hoʻi e neʻe, no laila e pāʻani ka antioxidant i loko o ka lāʻau i kahi hopena pale mau o nā ʻano ʻehā:

1, Hoʻonui i ke kaumaha molekala o ka antioxidant.
2, ka hana ʻana o nā antioxidants a me ka hoʻopaʻa ʻana i nā kemika.
3、Hoʻopili ʻia ka antioxidant ma ka ʻōpala ma mua o ka hana ʻana.
4, i ke kaʻina hana, no laila ka monomer me ka hana pale a me ka copolymerization monomer rubber.
ʻO ka antioxidant i nā ʻano hana ʻekolu hope, i ʻike ʻia i kekahi manawa he antioxidant reactive a i ʻole antioxidant bonding polymer.
