recent progress in the rubber antioxidants Rubber Auxiliary Agent,in this review, we systematically review the recent progress of antioxidants for rubber. we first give a brief introduction of the oxidation process and oxidation mechanism for rubbers. then, we present the strategies to improve the anti-oxidative efficiency of rubber antioxidants.
the antioxidative effect of silica-s-tp for rubber composite is superior to for the traditional antioxidants such as 4020, rd, 2246 and 264, and the high efficiency free radical capturing activity of silica-s-tp was stem from the polyphenol on the silica surface.
rubber antioxidants and their transformation products
amine antioxidants are the main rubber antioxidants produced and used in china, of which 6ppd and 2,2,4-trimethyl-1,2-dihydroquinoline (tmq, rd) have the highest production, accounting for more than 80% of the total amine antioxidants.
analysis of rubber antioxidant tmq (rd) in different rubber,this paper provides an in-depth analysis of rubber antioxidant tmq (rd)'s application in various rubber products, highlighting its anti-aging benefits and improving performance in all-steel and semi-steel radial tires, hoses, and belts.
first insights into 6ppd-quinone formation from 6ppd
p-phenylenediamines (ppds), an important type of rubber antioxidants, have received little study on their environmental fate, particularly for their vital photodegradation process in water environment.
transformation products of tire rubber antioxidant 6ppd for sale,6ppd, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (tp), 6ppd-quinone (6ppd), during exposure to gas-phase ozone. important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of tps from 6ppd ozonation.

in this review, we systematically review the recent progress of antioxidants for rubber. we first give a brief introduction of the oxidation process and oxidation mechanism for rubbers.
rubber antioxidants and chemical 6ppd,in this review, we first summarize the category and application of rubber antioxidants in the world, and then demonstrate the formation mechanism of their tps in the environment, emphasizing their influence on the ozone oxidative degradation.

the aging of rubber is considered a huge problem. through the process of aging little amounts of oxygen are absorbed by rubbers as (nr) and (sbr) or their vulcanizes. these lead to a major change in their physico‒mechanical properties. consequently it is important to incorporate antioxidants to rubber mixes to protect the rubber
synthesis and properties of a novel reactive and low,the addition of antioxidants to rubber is one of the most economical and effective methods for delaying rubber aging. however, antioxidant migration can cause environmental pollution. to address this issue, a new reactive antioxidant was synthesized via the chemical bonding of glycidyl methacrylate (gma) and p-aminodiphenylamine (ppda). the
- What are rubber antioxidants?
- Rubber antioxidants are defined as substances that could delay the aging of polymer compounds and prolong the service life of rubber products by inhibiting oxidation, heat, or light radiation . To date, the annual global consumption of rubber antioxidants is over 700,000 tons, accounting for about 40% of the total amount of rubber additives.
- Are rubber antioxidants harmful to human health?
- As shown in Table 1, many commonly used rubber antioxidants are damaging to human health and the environment. For example, the antioxidant MB Antioxidants are indispensable additives in the rubber industry as they enhance the reliability and service life of the rubber product by protecting it from degradation.
- What are the future trends of rubber antioxidants?
- The perspectives on the future trends of rubber antioxidants have been presented. Elastomers, especially diene-rubbers containing unsaturated double carbon bonds in the main chains, are vulnerable to thermal/oxygen aging, which would make the elastomers less elastic and result in earlier failure of the elastomer products.
- Can rubber antioxidants contain rare-earth ions?
- The recently reported rubber antioxidants containing rare-earth ions are summarized in Fig. 4, for instance, Sun et al. prepared a novel hindered phenol rare-earth complex (DTSm) (Fig. 4 f) by a simple and green method using 3,5-di-tert-butyl-4-hydroxybenzoic acid (DT) and samarium chloride hexahydrate (SmCl 3 ·6H 2 O) via coordination reaction.
