Okutegeeza:

Ebikolwa eby’okukwatagana (synergistic effects) eby’ebirungo ebiziyiza (rubber anti-ebirungi mulimu okukwatagana wakati w’ebitundu (intramolecular synergism).Okukwatagana (intramolecular synergy), era ekimanyiddwa nga self-, kitegeeza nti anti-ekirungo ekigimusa kirimu ebibinja ebikola ebingi eby’okuziyiza obuwuka obuleeta obulwadde, ebirina ebikolwa eby’okugatta ku buli kimu.

1. Enkolagana wakati w’enkwatagana (intermolecular synergies) enkolagana wakati w’ebitundu (intermolecular synergies) eyinza okwawulwamu ebika bino wammanga :(1) enkolagana zonna zitegeeza enkolagana ezikolebwa okugatta ebirungo ebiziyiza obuwuka obuleeta obulwadde n’enkola y’emu ey’ekirungo ekiziyiza obuwuka obuleeta obulwadde;(2) hetersynergistic effect kitegeeza ekikolwa eky’okukwatagana wakati w’ebirungo ebiziyiza obuwuka obuziyiza obuwuka obuziyiza obuwuka obuleeta obulwadde bwa antioxidant n’enkola ez’enjawulo eziziyiza obuwuka obuziyiza obuwuka obuleeta obulwadde.

(1) are synergy when two different space steric hindrance of hindered phenol, or two kinds of structure and activity of different amine stabilizer, or an aromatic amine and 1 kind of hindered phenolic antioxidant compound, when using highly active stabilizer can effectively capture the oxidation of free radicals or oxygen free radicals, low activity of the stabilizer can provide hydrogen atoms, that highly active stabilizer Regeneration, okukola synergy, okukuuma obusobozi obuziyiza obuwuka obuleeta obulwadde bwa 'antioxidant'.

(2)the typical example of heterogeneous synergistic effect is the combination of main anti-aging agent and auxiliary anti-aging agent.There is synergistic effect between phenolic antioxidant and phosphite.Phenolic anti-aging agent as a kind of main antioxidant, there is a lively hydrogen atom (o-h) in the molecule, this hydrogen atom is more active than the hydrogen atom on the rubber carbon chain (including the hydrogen double bond on the carbon chain), the hydrogen atom first with the macromolecular chain free radical R?Or ROO?Combine to form hydroperoxides and stable phenolic oxygen radicals (ArO?)..Due to the ArO?The increase of the ortho-substitution cardinal number or its branches, namely, the increase of its spatial hindrance effect, can make it protected By the larger adjacent volume groups and improve the stability.Era, olw’okuba aro?Mu nkola y’emu ennene eyungibwa n’empeta ya benzene, enywevu nnyo era erina emirimu emitono, kale tesobola kutandikawo nkola ya lujegere, naye esobola okugatta n’ekirala ekikola eky’eddembe, okukomyawo free radical emu nate, n’okukola ekirungo ekinywevu ennyo, okusobola okukomya okukomya enzirukanya y’olujegere.Aro eno?Aro eno okutebenkera kuno okusobola okugumira rapid rapid custent {1} okukebera okukkakkana okukkakkanya ekirungo kya chain.Aro?Aro eno? also reduce chain transfer reaction, thus improving its antioxidant performance.Hydroperoxides are harmful intermediates that catalyze thermal oxidation.However, phenolic antioxidant cannot decompose hydroperoxide by itself, so when phenolic antioxidant is used alone, it is difficult to achieve the ideal effect of aging prevention.Although phosphite does not have the ability to capture free radicals of peroxide, it can decompose hydroperoxide, thus inhibiting Okuvunda kwa kapiira olw’enkola ya autocatalytic.Naye, okutebenkera kw’amazzi mu phosphorous esters kwa bubi, ekivaako okukendeera kw’obutebenkevu bwazo obuziyiza obuwuka obuleeta obulwadde.Okutebenkera kw’amazzi okwa phosphite anti-okukaddiwa kukwatagana n’okuziyiza steric, kikakasibwa nti ekirungo kya phosphorus mu nsengekera y’enjegere. Hydrogen peroxide decomposition agent esobola okutuuka ku bikolwa ebijjuliza era esobola okukola omulimu omulungi ogw’okukwatagana.N’olwekyo, ebirungo bingi ebizibu ebiziyiza-ebikolebwa bikolebwa phenol ne phosphorous acid ebizibiddwa.

. Anti-Ekirungo ky’okukama n’ekirungo ekiyamba-ekiyinza okukozesebwa okulongoosa obulungi ekirungo ekiziyiza-okuyita mu kirungo kya intramolecular.
