Description
Technical Field
The invention relates to a rubber sole and a preparation method thereof, belonging to the technical field of rubber shoe material production.
Background
Shoes are necessities of life. People have both aesthetic property and practicability for the quality requirements of shoes. For athletic shoes such as running shoes and basketball shoes, the wear resistance and slip resistance of the sole are two of the main performance criteria of concern. For casual shoes, children's shoes, etc., sole flexibility is one of the main performance indicators of concern. Different shoes have different performance requirements, and the same sole material is difficult to meet the performance requirements. Professor Gem, in patent CN 103059353A, teaches that the use of epoxidized trans-natural rubber in tires provides a balance of wet skid resistance, abrasion resistance and rolling resistance. In the fatigue and dynamic performance of epoxidized trans-isoprene rubber/natural rubber blend (polymer material science and engineering, 29 vol.29, 9 th page 44-47) professor of yaosmunda and the like, the epoxidized trans-isoprene rubber with the epoxy degree of less than 20% is used in combination with the natural rubber, so that the flexibility of the material can be obviously improved. However, there are few documents such as articles and patents relating to the application of trans-epoxidized natural rubber to shoe sole materials.

The epoxy degree of the epoxidized trans-natural rubber is 13-20%.
The anti-aging agent RD is a 2,2, 4-trimethyl-1, 2-dihydroquinoline polymer.
The anti-aging agent 4010NA is N-isopropyl-N' -phenyl-p-phenylenediamine.
The white carbon black is precipitated white carbon black.
The process oil is a naphthenic oil.
The silane coupling agent Si69 is bis- [ gamma- (triethoxysilyl) propyl ] tetrasulfide.
The accelerator DM is 2,2' -dithiodibenzothiazole.
The promoter TMTD is tetramethyl thiuram disulfide.
In addition, the invention also provides a preparation method of the rubber sole, which comprises the following steps:
(1) preparing a rubber compound: the mixing adopts a two-stage mixing process, and the temperature of an internal mixer is set to be 115 ℃ in the first stage; all raw materials except the accelerator DM, the accelerator TMTD and insoluble sulfur in the formula are added, and are subjected to banburying for 9 minutes and then discharged; adding the rubber compound obtained in the first mixing stage into an internal mixer with circulating water cooling, adding an accelerator DM, an accelerator TMTD and insoluble sulfur, continuously mixing for 15 minutes, and discharging;
