Abstract

The invention belongs to the field of rubbers, and particularly relates to a rubber resisting thermal ageing. The rubber resisting thermal ageing comprises the following components in parts by weight: 80-220 parts of natural rubber, 50-220 parts of hydrogenated acrylonitrile butadiene rubber, 3-10 parts of nano zinc oxide, 2-4 parts of sodium stearate, 15-65 parts of carbon black N100, 5-12 parts of a softener, 5-15 parts of reinforcing powder, 5-10 parts of sulphur, 2-5 parts of an antiager, 2-8 parts of calcium carbonate, 2-6 parts of a tackifier, 2-5 parts of naphthenic oil, 2-5 parts of white carbon black, 2-5 parts of a scorch retarder, 2-4 parts of phthalic acid dibutyl ester, 2-4 parts of diethyl dithiocarbamic acid, 2-4 parts of 2-thiol imidazoline, and 2-10 parts of a plasticizer. Compared with common rubber, the rubber resisting thermal ageing has the beneficial effects of good thermal ageing resistance and dynamic fatigue resistance, and is used as rubber products in fatigue state for long.

Description

technical field [0001] The invention relates to a rubber with thermal aging resistance, which belongs to the field of 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 practical value. ...
