Problems solved by technology

[0002] Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature. It can produce a large deformation under the action of a small external force, and it can return to its original shape after the external force is removed. During use, due to friction with other objects, resulting in The surface of the rubber is damaged or even loses its original performance, and the rubber is used for too long, and the aging speed becomes faster. With the frequent occurrence of electrical fire accidents, the flame retardant problem of wires and cables has gradually attracted the attention of countries all over the world. When the cable burns, it releases A large amount of smoke and toxic and corrosive gases are dangerous factors in fires, which hinder people's safe evacuation and fire fighting work, and cause serious losses of life and property. Good, and rubber materials that can effectively inhibit the occurrence of aging phenomena have become a technical problem that needs to be solved at present
