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 ℃.
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
recent progress in the rubber antioxidants Rubber Auxiliary Agent
therefore, for a real application, the antioxidants are indispensable to retard the thermal-oxidative-aging process of the rubber composites and then prolong the service life. in this review, we systematically review the recent progress of antioxidants for rubber.
antioxidant 4010na-zhejiang huangyan zhedong rubber auxiliary,natural rubber, synthetic rubber and latex with excellent general antioxidant, excellent protective properties of ozone cracking; also the heat, oxygen, light and aging two protective agent.

the complexity of thermo-oxidative aging factors along with the lack of quantitative tools significantly hampers its applications. so, building a screening strategy to quickly and easily find an appropriate and eco-friendly ao is imperative. in this study, we chose natural rubber (nr) as a matrix and provided
highly aging-resistant elastomers doped with antioxidant,a novel aging-resistant styrene-butadiene rubber (sbr) composite is prepared using the antioxidant n-isopropyl-n'-phenyl-p-phenylenediamine (4010na) loaded inside of halloysite clay nanotubes and used as filler.

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
molecular simulation and experimental study on the damping,when 4010na is added at 32 phr, the composite has better damping properties, mechanical properties, and aging resistance, which provides a new insight for the construction of high performance elastomer composites.
the aging properties and phase morphology of silica filled
large amounts of antioxidants are used in unsaturated rubber composites, such as butadiene rubber (br), which would inevitably cause surface discoloration. in this study, silicone rubber (vmq) was blended with br for improving its anti-aging properties.
recent progress in the rubber antioxidants Rubber Auxiliary Agent,various external factors, including oxidative agents (such as oxygen), heavy metals, uv rays, ozone, mechanical stress, heat, and aggressive chemicals, etc., could accelerate rubber aging. this review mainly focused on thermo-oxidative aging because it is the most common aging type for rubbers.
- What causes oxidative aging of rubber?
- Various external factors, including oxidative agents (such as oxygen), heavy metals, UV rays, ozone, mechanical stress, heat, and aggressive chemicals, etc., could accelerate rubber aging. This review mainly focused on thermo-oxidative aging because it is the most common aging type for rubbers.
- What is thermo-oxidative aging of rubber?
- This review mainly focused on thermo-oxidative aging because it is the most common aging type for rubbers. The oxidative degradation of rubber proceeds by a free-radical chain reaction mechanism . As shown in Fig. 1a, rubber aging processes have three distinct phases: (i) Initiation, (ii) Propagation, and
- 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) .
- 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.
