Abstract

The invention discloses high-elastic glue for an inflatable solid tire and a preparation method thereof. The high-elastic glue is prepared from natural rubber, chloroprene rubber, ethylene-vinyl acetate copolymer, zinc oxide, stearic acid, sulphur, accelerant, gum easy T-78, tackifier, anti-aging agent, and filling agent. The preparation method includes steps of firstly, smelting the natural rubber, the chloroprene rubber, ethylene-vinyl acetate copolymer, and zinc oxide, and acquiring first section glue; then adding stearic acid, sulphur, and accelerant and smelting for 1-2 min; adding gum easy T-78, tackifier, anti-aging agent, and filling agent, and continuing to smelt for 3-4 min; discharging glue, and acquiring the high-elastic glue. The high-elastic glue is applied to a middle layer of the inflatable solid tire, thus the tire has good damping and buffering performances, and also has a certain anti-fatigue performance; thus the service life and the use safety of the solid tire are greatly prolonged; the high-elastic glue has good application value.

Description

technical field [0001] The invention relates to the technical field of solid tires, in particular to a high elastic rubber for pneumatic solid tires and a preparation method thereof. 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. [0003] In order to improve the elas...
