Problems solved by technology

[0002] Many sole materials on the market have a beautiful appearance, but they are not very good to wear. For example, the soles of some shoes are relatively hard and wear-resistant. None of them have a lot of wear and tear, but this kind of shoes must fit very well, otherwise the feet can only be accommodated to the shoes, which will make the feet very uncomfortable; there are also some shoes with soft soles, and the soles are larger or smaller. I can make do with it and won’t rub my feet, but the soles of this kind of shoes are easy to wear. After wearing it for a few months, some parts of the sole surface will be worn out, causing deformation of the shoes, and walking will be unstable.

Embodiment 1

[0010] A preparation method for wear-resistant shoe soles, the method comprising the following steps: weighing the following raw materials according to the mass parts: 70-78 parts of EPDM rubber, 11-13 parts of carbon black, 5-7 parts of triethylaluminum, 10-12 parts of p-nitrophenol, 10-12 parts of polystyrene, 30-35 parts of natural 3L rubber, 5-8 parts of polyvinyl alcohol, 11 parts of talcum powder; When the temperature reaches 110-113°C, all raw materials have been mixed evenly, and the mixture is poured out; then the mixture after banburying is granulated by a granulator to obtain granules with a diameter of 2-3cm. cooling in a water tank, and then drying at room temperature; injection molding the dried pellets at a mold temperature of 190±3°C and a vulcanization time of 250±10 seconds to obtain shoe soles.

[0011] The main properties of the prepared sole are as follows: Tensile strength MPa: 24, % elongation at break: 580, % permanent deformation: 32, Shore hardness: ...

Abstract

The invention discloses a method for preparing a wear-resistant sole, which comprises the following steps of weighing the following materials in weight parts: 70-78 parts of ethylene propylene diene rubber, 11-13 parts of carbon black, 5-7 parts of aluminum triethyl, 10-12 parts of p-nitrophenol, 10-12 parts of polystyrene, 30-35 parts of natural 3L rubber, 5-8 parts of polyvinyl alcohol and 11 parts of talcum powder; mixing the weighed raw materials together and then putting the materials into an internal mixer for banburying; pouring out the mixture after all the raw materials are evenly mixed when the temperature reaches 110-113 DEG C; then pelletizing the banburied mixture via a pelletizer to obtain granules, and then putting the granules into a water tank for cooling and then drying the granules under room temperature; finally injection molding the dried granules so as to obtain the sole. The sole prepared by the invention is greatly improved in wear resistance on the premise of not influencing the elasticity, comfort and other properties, and the sole has no toxic or polluting effects and also guarantees safety and environmental friendliness.

Description

technical field [0001] The invention discloses a preparation method of a wear-resistant shoe sole. technical background [0002] Many sole materials on the market now have a beautiful appearance, but they are not very good to wear. For example, the soles of some shoes are relatively hard and wear-resistant. After wearing for a long time, the soles do not have a lot of wear and tear, but this kind of shoes must fit very well. Otherwise, you have to adapt your feet to the shoes, which will make your feet very uncomfortable; there are also some shoes with softer soles, larger or smaller soles, which can be accommodated without grinding your feet, but this kind of shoes The sole of the shoe is easy to wear and tear. After wearing it for several months, some parts of the sole surface will be worn out, causing deformation of the shoe, and walking will be unstable. Contents of the invention [0003] The object of the present invention is to provide a method for preparing wear-...
