Abstract

The invention discloses a preparation method of a high-elasticity solid tyre material. The high-elasticity solid tyre material is prepared from the following raw materials in parts by weight: 40 to 65parts of natural rubber, 12 to 20 parts of chloroprene rubber, 10 to 12 parts of stearic acid, 8 to 12 parts of aromatic hydrocarbon oil, 2.5 to 4.5 parts of graphene, 12 to 18 parts of carbon black,0.6 to 2.2 parts of gum easy T-78, 10 to 12 parts of tackifier, 5 to 8 parts of carbon nanotube, 2 to 6 parts of silane coupling agent, 4 to 8 parts of antiager, 12 to 18 parts of filler, 6 to 10 parts of accelerant and 4 to 8 parts of vulcanizer. According to the preparation method disclosed by the invention, the tyre has the advantages of better damping and cushioning performance, certain fatigue resistance, capability of greatly prolonging the service life and improving the utilization safety of the solid tire and better application value.

Description

technical field [0001] The invention relates to the technical field of solid tires, in particular to a method for preparing high-elastic solid tire material. Background technique [0002] Solid rubber tire is a kind of industrial vehicle tire used under high load and harsh service conditions, and is widely used in various industrial vehicles, military vehicles, construction machinery and sky trains, etc. However, during the driving process of the vehicle, the temperature of the solid rubber tire rises significantly, and there are phenomena such as high-temperature bursting and chipping. Especially on off-road and mining roads, the solid tire tread rubber has poor cutting resistance. Solid tire tread rubber materials must have comprehensive excellent properties such as high modulus, low heat generation, high thermal conductivity, high fatigue, high strength, and tear resistance, in order to meet the needs of use. Contents of the invention [0003] The purpose of the presen...
