Rubber production method, rubber and tire
A production method and rubber technology, which can be used in special tires, tire parts, transportation and packaging, etc., can solve the problems of low production degree of solution-polymerized styrene-butadiene rubber, increased consumer use costs, and high rubber costs. Achieving the effect of low price, improved grip performance and high hardness

Example Embodiment
[0057] Example 1
[0058] Select any husks of walnuts, pistachios, pine nuts and longevity fruits, crush the husks into husk powder with a particle size of 88μm; add 24 parts of husk powder to 222.5 parts of rubber material to form a masterbatch material; Mix the masterbatch materials at 150℃ for 5 minutes to form a masterbatch; add final compounding materials to the masterbatch, pass through an open mill, and vulcanize at 150℃ for 10 minutes to form rubber .
[0059] The rubber material includes (the following are all mass scores):
[0060] Solution polymerized styrene butadiene rubber (SSBR, bound styrene content is about 21%, vinyl content is about 68%, glass transition temperature Tg is about -21 ℃) 60 parts, high cis butadiene rubber (BR9000, cis 1,4 -Butadiene content is about 97%, glass transition temperature Tg is about -107℃) 40 parts, carbon black (N234) 40 parts, white carbon black (7000Gr) 30 parts, zinc oxide (powdered zinc oxide) 5 parts, Stearic acid (granulated ste...
Example Embodiment
[0064] Example 2
[0065] The particle size of the husk powder was crushed to 250 μm, and the other conditions were the same as in Example 1, and finally rubber was formed. The prepared rubber is tested for performance: the Shore hardness is 60°, and the gripping performance (ie, friction index) is 103.
Example Embodiment
[0066] Example 3
[0067] The particle size of the husk powder was crushed to 500 μm, and the other conditions were the same as in Example 1, and finally rubber was formed. The prepared rubber was tested for performance: the Shore hardness was 63°, and the gripping performance (ie friction index) was 108.
