Problems solved by technology

But this technology has the following disadvantages: 1. As a means of transportation, especially shared bicycles, the general riding speed is about 8-12 km/h, and the speed of electric bicycles will reach 25 km/h, or even higher , while mopeds and electric tricycles can reach a speed of 50 km/h
Therefore, the material produced by this technology cannot meet the requirements of electric vehicle tire compression deformation
[0006] In order to develop tire materi...

Abstract

The invention discloses a non-pneumatic tire material taking thermoplastic vulcanized rubber as a base material and a preparation method of the non-pneumatic tire material, and belongs to the field ofmodified polymer materials and non-pneumatic tires. The material mainly comprises thermoplastic vulcanized rubber, a styrene elastomer, a hydrogenated styrene elastomer, a plasticizer, polypropylene,polyethylene, a filler, a hyperbranched polymer, a compatilizer, an antioxidant, a wear-resistant anti-slip agent and an ultraviolet light absorber. The preparation method comprises the following steps: mixing and stirring the thermoplastic vulcanized rubber, the styrene elastomer, the hydrogenated styrene elastomer and the plasticizer, mixing the rest materials, and carrying out melt mixing to obtain the target product. The non-pneumatic tire material prepared by the preparation method has the advantages of wear resistance, skid resistance, fatigue resistance, high toughness, high elasticity, low possibility of compressive deformation and the like, can effectively reduce the safety risks of air leakage, tire burst and the like in the driving process of a vehicle, can be recycled, and hasthe characteristics of greenness and environmental protection.

Description

technical field [0001] The invention belongs to the field of modified polymer materials and non-pneumatic tires, and in particular relates to a non-pneumatic tire material with thermoplastic vulcanizate (TPV) as a base material and a preparation method thereof. Background technique [0002] At present, according to the data shown in public reports, it is found that the total number of electric bicycles in China has reached 250 million, and China has become the world's largest consumer of electric bicycles. With the accelerated development of the electric vehicle industry, its driving safety has also become an important focus of social development. Among them, non-pneumatic tires have the characteristics of airtightness, wear resistance, and no tire blowouts, and have become a new direction for the development of the tire industry. .
