Problems solved by technology

[0005] For this reason, the present invention provides a solid tire with strong flexibility and a preparation method. By using an accelerator instead of a traditional anti-aging agent, adding a mixture of zinc oxide and stearic acid in an appropriate proportion, the tire has a high degree of hardening, and the addition of a reasonable The proportioned foaming agent makes the tire have excellent flexibility, which solves the above-mentioned shortcomings of the existing solid tire

Abstract

The invention relates to a solid tire with high flexibility and a preparation method thereof. According to the technical scheme, the 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, a brightening agent, an anti-fatigue agent, stearic acid, coumarone resin, carbon black and an anti-wear agent. The solid tire with high flexibility and the preparation method have the beneficial effects that the accelerant ZS, the accelerant CZ and the accelerant DM are added according to a proper proportion, so that the tire has good elasticity and toughness and is environment-friendly, and the heat conduction performance of the tire is greatly improved by adding the zinc oxide into the natural rubber according to a proper proportion; 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 anti-fatigue agent and the tear-resistant resin are added according to a proper ratio, so that the tire is good in aging resistance, low in rolling resistance and stable in performance.

Description

technical field [0001] The invention relates to the technical field of solid tires, in particular to a solid tire with strong flexibility and a preparation method. 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 contact area of ​​the tire is large, the unit ground pressure is small, the load distribution is uniform, and the slippage on the road surface is small, s...
