Abstract

The invention discloses a light shock-absorbing solid tire and a preparation method thereof. According to the technical scheme, the light shock-absorbing solid tire comprises a main material and an auxiliary material, the main material comprises natural rubber, and the auxiliary material comprises an accelerant, an antioxidant, zinc oxide, sulfur, a foaming agent, a coupling agent, activated carbon fibers, glass fibers, stearic acid, coumarone resin, white carbon black and a foam stabilizer. The light shock-absorbing solid tire and the preparation method thereof have the beneficial effects that the accelerator ZS, the accelerator CZ and the accelerator DM are added according to a proper proportion, so that the tire has good elasticity and toughness and is environment-friendly, the heat conduction performance of the tire is greatly improved by adding the zinc oxide according to a proper proportion into the natural rubber, and the service life of the tire is prolonged. The tire burst probability is reduced in the tire using process; a proper proportion of sulfur is added, so that the vulcanization performance is improved; the glass fibers and the tear-resistant resin are added according to a proper proportion, so that the tire is good in ageing resistance, low in rolling resistance and stable in performance.

Description

technical field [0001] The invention relates to the technical field of shock-absorbing solid tires, in particular to a lightweight shock-absorbing solid tire and a preparation method thereof. Background technique [0002] Solid tire is a kind of special automobile tire. It does not use cord as the skeleton and does not need to be inflated, so it does not need inner tube or airtight layer. Solid tire is only used for high-load vehicles or machinery running at low speed, or machinery with fixed position. It is mainly suitable for For special vehicles such as anti-riot vehicles, banknote transport vehicles, anti-terrorist vehicles, engineering vehicles, forestry machinery, etc., the tread of radial tires has high rigidity and small circumferential deformation. Harder rubber can be used as the tread material, so it has good wear resistance and The ground area of ​​the tire is large, the unit ground pressure is small, the load distribution is uniform, and the slippage on the road...
