synergistic effects of antioxidant and silica on enhancing,in this work, the thermo-oxidative aging performance of antioxidant n-isopropylN'-phenyl-p-phenylenediamine (4010na)/silica (sio2)/natural rubber (nr) composite was evaluated by the...
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.
4010na rubber antioxidant: enhancing durability
4010na is a widely used rubber antioxidant that plays a crucial role in improving the durability and performance of rubber products. this article provides an in-depth overview of 4010na, highlighting its characteristics, applications in rubber product manufacturing, compatibility with other products, and essential cons
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

Oxidative aging, the addition of synthetic antioxidants to the rubber matrix has been used effectively.6,7 Antioxidants are generally considered to be effective additives that protect materials from subsequent aging and can serve as inhibitor components in polymers such as plastics and rubbers.
highly aging-resistant elastomers doped with antioxidant,styrene–butadiene rubber with 27 wt % halloysite loaded with 4010na shows marked increase in aging resistance and promising future of halloysite as a functional rubber filler. keywords: aging resistant

in this study, we chose natural rubber (nr) as a matrix and provided a screening strategy based on diverse natural phenolic antioxidants to evaluate their ability in protecting nr composites. thymol, α-tocopherol, and lipid-soluble epigallocatechin gallate (lsegcg) were chosen from 18 natural phenolic antioxidants as potential alternative
rubber antioxidants and their transformation products,among them, antioxidant 2246 has a good performance to protect rubber from aging caused by heat, oxygen, and metals. because hydrogen in phenolic antioxidants can combine with the oxygen in air, their antiaging efficiency is therefore lowered compared with amine antioxidants [21,22].

synergistic effects of antioxidant and silica on enhancing,in this work, the thermo-oxidative aging performance of antioxidant n-isopropylN'-phenyl-p-phenylenediamine (4010na)/silica (sio 2)/natural rubber (nr) composite was evaluated by the variations of mechanical properties and chemical structure after aging at 100 ℃.
- Which antioxidants are used in rubber vulcanization?
- The amine and phenolic antioxidants are the most widely used rubber antioxidants (Fig. 1 b and c). Generally, the phenolic antioxidants have poor antioxidative efficiency (compared to amine antioxidants) and they can delay vulcanization, but they cause little discoloration problems.
- Are rubber antioxidants a rational design?
- The development of medical antioxidants also inspires the rational design of rubber antioxidants. Recently, Sun, et al. synthesized a novel antioxidant (APPT) containing aromatic amine, thiourea and allyl groups by the reaction between N-phenyl-p-phenylenediamine and allyl isothiocyanate (Fig. 3 b) .
- 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.
- Does 4010na/cb/Nr composite increase thermo-oxidative aging resistance?
- The results shall indicate that, in comparison with 4010NA/CB/NR composite, there existed synergistic effect of antioxidant 4010NA and silica in 4010NA/SiO2 /NR composite on greatly enhancing thermo-oxidative aging resistance of NR material.
