Rubber sheet's ozone and aging protection

The surface of the rubber sheet is easily oxidized with ozone, causing aging and damage of the rubber sheet. In the early days, physical methods were generally used for protection: a barrier was placed on the surface of the rubber sheet to avoid contact between the ozone and the rubber sheet. However, it has been found in practice that physical protection methods can only protect static rubber products. Therefore, using dynamically chemical protection methods for the rubber sheet products.

The following is a brief introduction to the principle of physical protection: physical protection means spraying a layer of paraffin on the surface of the rubber sheet to form a protective film. Paraffin can also be added to the rubber material to form a protective film after it is sprayed out of the rubber sheet's surface. Thereby preventing the erosion to the surface of the rubber sheet by ozone.

So what is the chemical protection method of the rubber sheet? What is the principle of chemical protection? Chemical protection refers to adding organic compounds to rubber sheets and using chemical reactions to prevent aging. Such organic compounds generally refer to chemical antiozonant. There is no unified statement on the mechanism of anti-ozonant action of rubber sheets. Common mechanisms include: rubber sheet protective film mechanism, rubber sheet scavenger mechanism, self-healing mechanism of oil-resistant rubber sheet, and suturing mechanism of insulating rubber sheet.
