Wear-resisting sole material and preparation method thereof

Abstract

The invention relates to a formula of a rubber sole material and an improvement of the preparation method of the rubber sole material. The wear-resisting sole material comprises the following components by weight percent: 50-60% of natural rubber 3L, 3-5% of accelerator, 40-45% of filler, 1-1.5% of hardener and 1.5-2% of vulcanizing agent, wherein the hardener is high styrene; and the acceleratoris the mixture of inorganic accelerator, polyethylene glycol, stearic acid, antioxidant and tackifier and the accelerator also contains organic accelerator which is perferably selected from accelerator D, accelerator M and accelerator DM. The sole material of the invention is prepared from good natural rubber by adding the accelerator with various functions; and the sole prepared from the material has light weight, good wear resistance, water resistance and good heat retention property and is suitable to be used as the sole of the shoe with high wear strength such as tennis shoe and outdoor sneaker.

Description

A kind of wear-resistant shoe sole material and preparation method thereof technical field The invention relates to the technical field of polymer materials, in particular to the improvement of the formula of a rubber shoe sole material and its preparation method. Background technique At present, rubber sole materials mainly include synthetic rubber soles, polyurethane soles, and ethylene and acetate copolymer sole materials. Polyurethane soles have good elasticity, formability, and recovery, but their ventilation and water absorption are poor; ethylene and acetate resin copolymer soles have poor elasticity, formability, recovery, ventilation, and water absorption; synthetic rubber The sole needs to add other ingredients to improve its performance. However, the addition of other ingredients also leads to a decrease in the transparency of the sole plate, and these three sole materials are not easy to decompose, difficult to melt and reuse, and will seriously pollute the en...

AI Technical Summary

Problems solved by technology

Polyurethane soles have good elasticity, formability, and recovery, but their ventilation and water absorption are poor; ethylene and acetate resin copolymer soles have poor elasticity, formability, recovery, ventilation, and water absorption; synthetic rubber The sole needs to add other ingredients to improve its performance

However, the addition of other ingredients can also lead to a decrease in the transparency of the sole plate, and these three sole materials are not easy to decompose, difficult to melt and reuse, and will seriously pollute the environment after being discarded.
