Abstract：People who have used rubber products often have the experience that the products will age after a long period of use. Once this happens, not only will the products be easily damaged, but the use effect will also become poor. Specifically, the aging phenomenon of such products is generally caused by the following factors:
People who have used rubber products often have the experience that the products will age after a long period of use. Once this happens, not only will the products be easily damaged, but the use effect will also become poor. Specifically, the aging phenomenon of such products is generally caused by the following factors:
1. Oxygen: Oxygen reacts with molecules in rubber products, which can easily lead to the breakage or excessive cross-linking of molecular chains within the product material. Once this occurs, it can cause changes in material properties, leading to aging of the product.
2. Ozone: Ozone has high chemical activity and is more destructive to rubber product molecules. When products are exposed to too much ozone, they are prone to aging.
3. Heat: High temperature can cause rubber to undergo thermal cracking or cross-linking, and can also accelerate the oxidation reaction rate of materials, so heat can also cause aging of products.
4. Light: The impact of this factor on the aging of rubber products is mainly reflected in the ultraviolet rays in sunlight. If the products are exposed to sunlight for a long time, they are prone to aging under the influence of ultraviolet rays.
In addition, mechanical stress, moisture, and oil can all cause rubber products to age
