Description

technical field [0001] The invention belongs to the technical field of rubber, and in particular relates to an anti-aging rubber. Background technique [0002] Rubber is a highly elastic polymer material with reversible deformation. It is used to manufacture aircraft, warships, automobiles, tractors, harvesters, irrigation and drainage machinery, medical equipment and other equipment. It is divided into two types: natural rubber and synthetic rubber. Natural rubber is processed by extracting gum from rubber trees, rubber grass and other plants, while synthetic rubber is obtained by polymerization of various monomers. The aging of rubber refers to the aging of rubber and its products under the influence of light, heat, ozone and mechanical pressure during use and storage, resulting in cracking, stickiness, hardening, softening, pulverization, discoloration, Destructive changes such as mildew. Among them, natural rubber has high elasticity and a little plasticity at room tem...
