Problems solved by technology

[0002] In recent years, in the design of rubber, high performance and high technology are advancing rapidly, and the amount of rubber used also tends to increase; when rubber is used in a ship environment, it is subjected to heat energy, light radiation energy for a long time, plus oxygen, moisture, etc. And metal ions participate in the chemical reaction, and gradually appear the aging phenomenon of becoming soft and sticky, hard and brittle or cracked, making its physical and mechanical properties deteriorate or even lose its original properties, resulting in failure of the rubber during use. How to prepare A rubber with good thermo-oxidative stability, aging resistance and excellent mechanical properties has become a technical problem to be solved at present
