Embodiment 1

[0024] A low-hardness and high wear-resistant anti-skid sole material for shoes, which includes the following raw materials in parts by weight:

[0025] The core raw materials mainly include the following four types, rare earth butadiene: 25 parts, NBR nitrile rubber: 5 parts, carbon black: 15 parts, ointment oil: 20 parts; also include: 3L: 50 parts, styrene-butadiene: 20 parts, black Masterbatch: 6 parts, white carbon black: 15 parts, diethylene glycol: 3 parts, 99 zinc oxide: 5 parts, stearic acid: 1 part, PEG4000: 3 parts, SI69: 1.5 parts, antioxidant: 3 parts, Wax: 1 part, DM: 2 parts, TMTM: 0.4 parts, S: 2.2 parts. Wherein, the ointment oil adopts the ointment oil imported from Germany.

[0026] The preparation method of this sole material is as follows:

[0027] (1) Put the main rubber into the internal mixer and mix evenly, the mixing temperature is 60 degrees, and the mixing time is 2 minutes;

[0028] (2) Add 2 / 3 of white carbon black and powder oil, the mixing te...

Embodiment 2

[0034] The difference from Example 1 is that the preparation method of the sole material is as follows:

[0035] (1) Put the main rubber into the internal mixer and mix evenly, the mixing temperature is 80 degrees, and the time is 5 minutes;

[0036] (2) Add 2 / 3 of white carbon black and powder oil, the mixing temperature is 100 degrees, and the time is 2 minutes;

[0037] (3) Add the remaining amount of white carbon black and accelerators, the mixing temperature is 120 degrees, and knead for 2 minutes;

[0038] (4) When the material is discharged above 120 degrees, the rubber material is cooled and left for more than 24 hours as a mixing base rubber for use;

[0039] (5) Add the vulcanization accelerator to the base rubber in step (4) according to the amount, knead evenly on the open mill, and then punch out the semi-finished blanks with the size of finished products after being cooled.

[0040] (6) The semi-finished blank in step (5) is pressurized and vulcanized, the vulc...

Embodiment 3

[0042] The difference from Example 1 is that the preparation method of the sole material is as follows:

[0043] (1) Put the main rubber into the internal mixer and mix evenly, the mixing temperature is 70 degrees, and the mixing time is 3 minutes;

[0044] (2) Add 2 / 3 of white carbon black and powder oil, the mixing temperature is 95 degrees, and the time is 4 minutes;

[0045] (3) Add the remaining amount of white carbon black and accelerators, the mixing temperature is 110 degrees, and knead for 2 minutes;

[0046] (4) When the material is discharged above 120 degrees, the rubber material is cooled and left for more than 24 hours as a mixing base rubber for use;

[0047] (5) Add the vulcanization accelerator to the base rubber in step (4) according to the amount, knead evenly on the open mill, and then punch out the semi-finished blanks with the size of finished products after being cooled.

[0048] (6) The semi-finished blank in step (5) is pressurized and vulcanized, th...

Abstract

The invention provides a low-hardness high-wear-resistance non-slip sole material for shoes and a preparation method of the low-hardness high-wear-resistance non-slip sole material, wherein the sole material mainly comprises the raw materials in parts by weight: 25 parts of rare earth cis-butadiene, 5 parts of NBR butadiene-acrylonitrile rubber, 15 parts of carbon black and 20 parts of ointment oil. The wear resistance of the product is improved by matching rare earth cis-butadiene and butadiene-acrylonitrile rubber, the hardness of the product is reduced by matching German imported ointment oil with carbon black, the product is low in hardness, good in wear resistance and resistant to skid, the sole made of the product has good wear resistance and toughening effect, and the wear resistance and the skid resistance are improved while the characteristic of comfort in wearing due to low hardness is kept.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a low-hardness, high-wear-resistant anti-slip sole material for shoes and a preparation method thereof. Background technique [0002] The sole material is an accompaniment to footwear products. With the development of footwear products, the quality of sole materials has been continuously improved. Most of the traditional soles are made of natural materials, mainly animal leather, fiber fabrics (such as cotton, hemp, silk and wool, etc.), wood and natural rubber (NR); Varieties emerge in endlessly, mainly synthetic rubber (SR), plastics, thermoplastic elastomers (TEP) and metals. Low hardness and high wear resistance anti-slip material is a kind of thermoplastic rubber material. The sole made of this material has the characteristics of low hardness, super softness, high wear resistance, high elasticity and high anti-skid. [0003] With the continuous improvement of living standar...
