Problems solved by technology
[0002] Many shoe sole materials on the market now have excellent properties of beautiful appearance, wear resistance, oil resistance and corrosion resistance, but they have the disadvantages of poor toughness and poor heat resistance. In order to further improve the performance, a large amount of fillers, resins and oils are generally added products, not only will greatly increase the production cost, but also greatly increase the quality of the soles, which will make people feel uncomfortable when wearing them.

Embodiment 1
[0007] A method for preparing an ultra-light shoe sole material. The preparation steps of the method are as follows: 60-66 parts by mass of PP, 80-85 parts by mass of toluene diisocyanate, 50-52 parts by mass of polybutyl acrylate, 10 parts by mass of sulfur, 3 -6 parts by mass of stearic acid, 6-8 parts by mass of carbon black, 2.5-5 parts by mass of plasticizer, 3-6 parts by mass of paraffin-based petroleum and 5-6 parts by mass of polydimethylsilicone oil are added to the high-speed stirring mixer mixing for 10 minutes; then adding to a twin-screw extruder to melt and graft for 3 hours to obtain the shoe sole material. The performance testing results of the sole material are as follows: relative density: 0.22, hardness (A) 50, tensile strength / MPa: 2.85, rebound rate: 31%.

Abstract
The invention discloses a preparation method of an ultra-light sole material. The method comprises the preparation steps of: adding 60-66 parts by mass of PP, 80-85 parts by mass of toluene diisocyanate, 50-52 parts by mass of poly(butyl acrylate), 10 parts by mass of sulfur, 3-6 parts by mass of stearic acid, 6-8 parts by mass of carbon black, 2.5-5 parts by mass of a plasticizer, 3-6 parts by mass of paraffin base petroleum and 5-6 parts by mass of polydimethyl silicone oil into a high-speed stirring mixer to mix them for 10min; and then adding the mixture into a twin-screw extruder to carry out melt grafting for 3h, thus obtaining the sole material. The method has a simple preparation process and a low production cost, and the prepared product has the advantages of high wear resistance, good elasticity, as well as the properties of light weight and comfortableness.
Description
technical field [0001] The invention relates to a preparation method of an ultralight shoe sole material. technical background [0002] Many shoe sole materials on the market now have excellent performances of beautiful appearance, wear resistance, oil resistance and corrosion resistance, but they have the disadvantages of poor toughness and poor heat resistance.
