Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a high-elasticity nitrile rubber material. Background technique [0002] Rubber is a necessary material for the manufacture of aircraft, warships, automobiles, tractors, harvesters, irrigation and drainage machinery, medical equipment, etc. According to different sources, rubber can be divided into natural rubber and synthetic rubber. There are a few varieties of synthetic rubber that are similar to natural rubber in performance, and most of them are different from natural rubber, but both are high-elastic polymer materials, and generally need to be vulcanized and processed before they have practicality and use value. Synthetic rubber began to be produced in the early 20th century and has developed rapidly since the 1940s. Synthetic rubber is generally not as comprehensive as natural rubber in performance, but it has high elasticity, insulation, air tightness, oil r...
