Rubber antioxidant is an important additive of rubber products, which can improve the aging resistance of rubber products and extend their service life. However, different rubber materials and uses need to choose different rubber antioxidants, but also need to master the correct use method. This article will introduce how to choose and use rubber antioxidants to help you better understand and apply.
First, the role of rubber antioxidant
Rubber antioxidant is a chemical that can inhibit or delay the aging of rubber materials. It can effectively resist the destruction of rubber materials by oxygen, ozone, ultraviolet light and heat, thereby extending the service life of rubber products.
Second, how to choose the right rubber antioxidant
1. Choose according to the type of rubber material
Different rubber materials have different sensitivity to aging, so it is necessary to choose a suitable rubber antioxidant. For example, the sensitivity of natural rubber and synthetic rubber to oxygen and ultraviolet light is different, and the corresponding antioxidant needs to be selected.
2. Choose according to the use
Rubber products are used in different environments and conditions, so it is necessary to choose suitable rubber antioxidants to resist different aging factors. For example, rubber products used outdoors need to choose an antioxidant that can resist ultraviolet light and oxygen, and rubber products used in high temperature environments need to choose an antioxidant that can resist thermal aging.
3. Select according to the added dose
The added dose of rubber antioxidant has an impact on the anti-aging effect and the cost of use, so it is necessary to choose the appropriate added dose. Under normal circumstances, the added dose of antioxidants is between 0.1% and 2%, and the specific dose needs to be adjusted according to the conditions and requirements of use.
Three, how to use rubber antioxidant
1. Add a method
Add the rubber antioxidant to the rubber material in proportion and stir well. The method of mechanical stirring or manual stirring can be used to make the antioxidant and rubber material fully mixed.
2. Storage method
Rubber antioxidants need to be stored in a dry, cool, ventilated place, away from direct sunlight and high temperatures. At the same time, it needs to be sealed and stored to prevent moist air from entering.
Iv. Case analysis
Taking a rubber products factory as an example, in the process of producing rubber products, it is necessary to choose the appropriate rubber antioxidant for different rubber materials and uses. For example, when producing rubber products for outdoor use, it is necessary to choose an antioxidant that can resist ultraviolet light and oxygen; When producing rubber products for use in high temperature environments, it is necessary to choose an antioxidant that can resist thermal aging. At the same time, it is also necessary to choose the appropriate dosage according to the production cost and use requirements. In the process of use, it is necessary to master the correct adding method and storage method to ensure product quality and safety. Through reasonable selection and use of rubber antioxidants, the rubber products produced by the factory have longer service life and better performance, and improve the market competitiveness of the products.
