Problems solved by technology

[0003] At present, the thermoplastic elastomer materials used in the non-inflatable tire market have poor fatigue resistance and are prone to fatigue cracks after long-time riding; due to the poor temperature resistance of ordinary elastomer materials, after the surface temperature rises in summer, the tire deformation is large, and the tire The contact area increases, the riding resistance increases, and the riding comfort is significantly reduced
[0004] Patent 201510361760.X provides an anti-fatigue, temperature-resistant thermoplastic elastomer material for non-pneumatic tires, including 100-150 parts of ultra-high molecular weight hydrogenated styrene elastomer, 80-150 parts of white oil, 10-50 parts of polyphenylene ether, 20-50 parts of polypropylene, 5-15 parts of polyethylene, 5-15 parts of polyolefin blending toughening agent, 10-30 parts of mineral powder, 3-8 parts of silicone powder, 0.2-0.5 parts of stabilizer, the present invention must To a certain extent, it solves the fatigue resistance and high temperature resistance of thermoplastic elastomers, but the formula raw materials are relatively complicated and the preparation cost is high

Abstract

The invention belongs to the technical field of high polymer materials and specifically relates to a thermoplastic elastic material for producing a non-pneumatic tire and a preparation method of the thermoplastic elastic material. The thermoplastic elastic material comprises a hydrogenated styrene-ethylene-butadiene-styrene polymer, paraffin oil, polypropylene, a polyolefin elastomer, ethylene-propylene-diene monomer rubber and auxiliaries. The thermoplastic elastic material prepared by compounding the raw materials is small in specific gravity, excellent in surface elasticity, wear-resistant,high-temperature-resistant and low in cost; the preparation method of the thermoplastic elastic material for producing the non-pneumatic tire comprises the following steps: mixing the raw materials according to a certain proportion, and uniformly stirring the raw materials at room temperature to obtain a mixed material; delivering the mixed material into an extruder at constant speed to carry outextrusion; and carrying out pelletization after extrusion. The method is simple in process and high in production efficiency, and the prepared elastomer is good in consistency.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a thermoplastic elastic material used for making air-free tires and a preparation method thereof. Background technique [0002] For public bicycles at present, in order to reduce the maintenance cost of bicycles and improve the efficiency of use of bicycles, there are bicycle-free pneumatic tires on the market. At present, bicycle free air tires are mainly divided into two types, one is air free solid tires, and the other is air free hollow tires. The former is mainly a tire made of vulcanized rubber. Due to the limitations of vulcanized rubber processing, the structural design is relatively monotonous, the processing process is long, the tire has poor shock absorption capacity, and the riding comfort is poor. The non-inflatable hollow tire has a hollow structure, which improves the shock absorption effect, and the riding comfort is relatively good. Conside...
