Problems solved by technology

The solution-polymerized styrene-butadiene rubber used in the raw rubber system has a low degree of localization and high cost; the cost of dual-phase carbon black used in the carbon black reinforcement system is high; the use of silane coupling agents with monosulfide bonds in the vulcanization system more expensive
[0005] It can be seen that the cost of tire rubber to improve the grip performance in the prior art remains high, which greatly increases the cost of use for consumers

Embodiment 1

[0058] Select any shells from walnuts, pistachios, pine nuts and longevity fruits, and crush the shells into shell powder with a particle size of 88 μm; add 24 parts of shell powder to 222.5 parts of rubber to form a masterbatch material; Mix the masterbatch material at 150°C for 5 minutes to form a masterbatch; add the final mix material to the masterbatch, pass through an open mill, and vulcanize at 150°C for 10 minutes to form a rubber .

[0059] Among them, the rubber materials include (the following are all mass fractions):

[0060] Solution polystyrene butadiene rubber (SSBR, combined styrene content about 21%, vinyl content about 68%, glass transition temperature Tg about -21℃) 60 parts, high cis-butadiene rubber (BR9000, cis 1,4 -Butadiene content about 97%, glass transition temperature Tg 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 stearic acid) 2 parts,...

Embodiment 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 to finally form rubber. The prepared rubber was subjected to a performance test: the Shore hardness was 60°, and the grip performance (ie friction index) was 103.

Embodiment 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 to finally form rubber. The prepared rubber was subjected to a performance test: the Shore hardness was 63°, and the grip performance (ie friction index) was 108.

Abstract

The embodiment of the invention discloses a rubber production method. The rubber production method comprises the steps of: crushing shells into shell powder; adding 1-25 parts of the shell powder into every 100 parts of sizing material, so as to form masterbatch material; mixing the masterbatch material to form masterbatch; and adding final-batch material, and crosslinking to form rubber. By utilizing the production method disclosed by the invention, the surface roughness of the rubber is increased, the antiskid property of a tire is improved, and especially the driving of a vehicle on the slippery pavement and the snow and ice pavement; and meanwhile, as the shell belongs to the renewable resource, the shell is environment-friendly, is free of pollution and is accordant with requirements of green circular economy, the price is low, and the cost is lowered. The invention further provides rubber prepared by utilizing the preparation method. The invention further provides a tier prepared from the rubber.

Description

technical field [0001] The invention relates to a method for improving rubber tires, in particular to a rubber production method, rubber and tires. Background technique [0002] A tire is a rolling round rubber product assembled on a vehicle or machine, which can support the body, buffer external impacts, achieve contact with the road surface and maintain the driving performance of the vehicle. [0003] With the progress of society, people are more and more dependent on vehicles, and the safety requirements of vehicles are also getting higher and higher, especially the requirements for tire gripping performance, especially on slippery roads that are prone to traffic accidents, When driving on icy and snowy roads, the quality of tire gripping performance directly affects the safety of drivers and passengers. [0004] In the prior art, for the grip performance of tires, manufacturers have carried out research and attempts on the raw rubber system, carbon black reinforcement s...
