Abstract

The invention relates to the field of tire materials, in particular to a non-pneumatic tire compound, comprising a hydrogenated S-B(S)-S polymer and a coupled SEBS; the hydrogenated S-B(S)-S polymer The product is the hydrogenation product of the triblock S-B(S)-S polymer; the first block and the third block of the triblock S-B(S)-S polymer are styrene blocks , the middle block is a butadiene block, or a random block of styrene and butadiene; the chemical formula of the coupled SEBS is A n X; wherein, A is a hydrogenated styrene-butadiene block polymer segment or a hydrogenated styrene-butadiene-styrene block polymer segment; X is a coupling agent residue; n is an integer , and n is 1-4. The invention also discloses the application of the rubber compound; and a method for preparing a pneumatic tire by using the rubber compound. In the present invention, through the synergistic cooperation of the hydrogenated S-B(S)-S polymer and the coupled SEBS, the safety and anti-skid performance and shock absorption comfort of the air-free tire can be synergistically improved.

Description

Technical field: [0001] The invention relates to a hydrogenated S-B(S)-S block polymer mixed with a coupling type SEBS as a material for a bicycle air-free tire, which can improve the safety and anti-skid property and riding comfort of the tire. Background technique: [0002] Bicycle tires are divided into two types: non-pneumatic tires and pneumatic tires. Pneumatic tires have been limited in application due to their heavy weight, poor shock absorption, and poor riding comfort. However, with the improvement of processing technology and new material technology, as well as the large-scale launch of shared bicycles across the country, the use of air-free tires as bicycle tires can reduce human damage, reduce inflation and maintenance costs, and increase the service life of tires. [0003] Elastomers commonly used in bicycle tires include natural rubber, styrenic elastomers, ethylene-propylene-diene terpolymer EPDM (ie, ethylene propylene diene), ethylene-propylene copolymer E...
