Abstract

The invention belongs to the rubber field, and particularly relates to fatigue-resistant rubber. The fatigue-resistant rubber comprises the components in parts by weight as follows: 80-200 parts of natural rubber, 50-200 parts of hydrogenated nitrile rubber, 2-10 parts of nano-zinc oxide, 1-4 parts of sodium stearate, 15-50 parts of carbon black N100, 2-12 parts of a softening agent, 4-15 parts of reinforcing powder, 2-10 parts of sulfur, 1- 5 parts of an anti-aging agent, 1-8 parts of calcium carbonate, 1-6 parts of a thickening agent, 1-5 parts of naphthenic oil, 1-5 parts of white carbon black, 1-5 parts of an anti-scorching agent, 1-4 parts of dibutyl phthalate, 1-4 parts of zinc diethyldithiocarbamate, 1-4 parts of 2-imidazolidinethione and 1-10 parts of a plasticizer. The fatigue-resistant rubber has the benefits as follows: compared with common rubber, the rubber has good heat aging resistance and dynamic fatigue resistance, and can be used for rubber products required to be in the fatigue state for a long time.

Description

technical field [0001] The invention belongs to the field of rubber, in particular to a fatigue-resistant rubber. Background technique [0002] The local structural changes and the growth process of internal defects caused by rubber bearing alternating cyclic stress or strain are called rubber fatigue. Under dynamic tension, compression, twisting and shearing, the performance and structure of rubber products will change or be destroyed, which is the so-called fatigue damage. It reduces the mechanical properties of the material and eventually leads to cracking or complete fracture. The essence of rubber fatigue is the appearance of rubber aging under the action of force and heat, including flex fatigue and aging fatigue. There are many conditions for rubber to fatigue, for example, elongation or compression; periodic external force, etc. Fatigue-resistant rubber is widely used in our daily life and industrial production, and has extremely high pra...
