An antiozonant, also known as anti-ozonant, is an organic compound that prevents or retards damage caused by ozone. The most important antiozonants are those which prevent degradation of elastomers like rubber .

The term antiozonant denotes any additive that protects rubber against ozone deterioration. Most frequently, the protective effect results from a reaction with ozone, in which case the term used is chemical antiozonant. Ozone is generated naturally by electrical discharge and also by solar radiation in the stratosphere.

抗氧化剂 是指能减缓或防止 氧化作用 的 分子 （常专指生物体中）。 氧化是一种使 电子 自物质转移至 氧化剂 的 化学反应，过程中可生成 自由基，进而启动 链反应。 当链反应发生在细胞中， 细胞 便會受到破坏或凋亡。 抗氧化剂则能去除自由基，终止连锁反应并且抑制其他氧化反应，同时其本身被氧化。 抗氧化剂通常是 还原剂，例如 硫醇 、 抗坏血酸 、 多酚类。 [1] 抗氧化剂也是一种 汽油 中重要的添加剂。 它可以防止油料在储存过程中氧化变质形成胶质沉淀从而妨碍内燃 …

Antiozonants – are chemicals and / or waxes that “bleed” to the surface of a rubber article, to protect it against attack from ozone (O3). For long-term storage protection, some rubber articles are sealed with an exterior coating of wax or similar substance for additional protection against attack from ozone.

Jan 1, 1995 · Ozone cracking in elastomers can be characterised by two parameters: a threshold condition and a characteristic rate of growth. Many chemical additives can reduce the growth rate but the most potent also effectively raise the threshold by forming a …

All diene rubber vulcanizates contain free double bonds which are sensitive to attack by molecular oxygen and ozone. To reduce this sensitivity, they are usually formulated with active antiozonants, both to protect against the degrading effects of ozone and to improve the resistance to fatigue in dynamic applications.

Dec 4, 2000 · The term antiozonant, in its broadest sense, denotes any additive that protects an elastomer against ozone deterioration. Most frequently, the protective effect results from a reaction with ozone, in which case the term used is chemical antiozonant. Ozone is generated naturally by electrical discharge and also by solar radiation in the ...

Sep 24, 2006 · In present work a series of ethyl cyanoacetate, ethyl malonate and acetyl acetone derivatives containing, 3,5-dialkyl-4-hydroxybenzyl groups has been tested in isoprene rubbers as well as in their vulcanizates in order to evaluate their antiozonant capability.

antiozonant，英语单词，主要用作名词，作名词时译为“抗臭氧剂”。 [1] antiozonant E 抗臭氧剂 [1] Antiozonant is an ingredient that helps to prevent the exterior rubber surface from cracking, checking, oxidizing, and deteriorating. 它是一种可以防止外部的橡胶表面破裂、氧化甚至更加恶化的一种材料。 [1] antiozonant，英语单词，主要用作名词，作名词时译为“抗臭氧剂”。
