Effect of antioxidant structure on bromobutyl rubber composites' processability and age resistance
Bromobutyl rubber has numerous applications in industries such as tires, sealing capsules, and aerospace, so enhancing its aging resistance is a critical issue. However, the addition of amine antioxidants to Bromobutyl rubber results in the occurrence of unique storage hardening and storage scorching phenomenon, which lead to the deterioration of the rubber's properties. To examine the impact of various types of amine antioxidants on the storage stability and aging resistance of Bromobutyl rubber, we conducted comparative experiments using five types of amine antioxidants and one phenolic antioxidant. The purpose was to investigate the effect of amine antioxidants on the storage stability and overall performance of Bromobutyl rubber. The results indicate that the inclusion of p-phenylenediamine antioxidants (4020, 4010NA) greatly facilitates the occurrence of storage hardening and storage scorching phenomenon in Bromobutyl rubber, leading to a deterioration in rubber performance. Therefore, it is advisable to refrain from using high-activity p-phenylenediamine antioxidants when working with Bromobutyl rubber.
期刊介绍：
Reactive & Functional Polymers provides a forum to disseminate original ideas, concepts and developments in the science and technology of polymers with functional groups, which impart specific chemical reactivity or physical, chemical, structural, biological, and pharmacological functionality. The scope covers organic polymers, acting for instance as reagents, catalysts, templates, ion-exchangers, selective sorbents, chelating or antimicrobial agents, drug carriers, sensors, membranes, and hydrogels. This also includes reactive cross-linkable prepolymers and high-performance thermosetting polymers, natural or degradable polymers, conducting polymers, and porous polymers.
Original research articles must contain thorough molecular and material characterization data on synthesis of the above polymers in combination with their applications. Applications include but are not limited to catalysis, water or effluent treatment, separations and recovery, electronics and information storage, energy conversion, encapsulation, or adhesion.
