                   Effect of different antioxidants on the adhesion performance of
                      water-based adhesive adhering V-band wrapping adhesive

                 Abstract: By changing the anti-aging system in the V-belt wrapping adhesive formula system, the effects
             of different anti-aging systems on the physical properties of vulcanized rubber and the adhesion performance
             of water-based adhesive prepared from mixed rubber were studied. Research has shown that different anti-
             aging systems have no effect on the degree of vulcanization of the mixed rubber, but have a significant
             impact on the vulcanization rate of the mixed rubber; The combination system of antioxidant RD/MB has the
             best heat and oxygen aging performance for vulcanized rubber, while antioxidant 264 has the worst heat
             and oxygen aging performance for vulcanized rubber; As the amount of adhesive increases, it is detrimental
             to the adhesion performance of the water-based adhesive, and the physical and mechanical properties of
             the vulcanized rubber after thermal oxygen aging significantly affect the adhesion performance of the water-
             based adhesive.
