Abstract

The invention discloses a wear-resistant sole material and a manufacturing method thereof, and relates to sole materials. The wear-resistant sole material comprises the following components by weight:60-70 parts of butadiene rubber; 30-40 parts of natural rubber; 2-5 parts of activated zinc oxide; 2-5 parts of stearic acid; 4-6 parts of a foaming agent and 1.5-3 parts of a vulcanizing agent; 0.8-1.5 parts of an accelerant; 1-2 parts of an anti-aging agent; and 40-50 parts of modified filler. Hollow glass beads with good reinforcing and toughening effects are selected as filler in the rubber material and are modified to be dispersed and combined in a rubber base material, so that the sole material is good in wear resistance and tear resistance.

Description

technical field [0001] The invention relates to shoe soles, in particular to a wear-resistant shoe sole material and a manufacturing method thereof. Background technique [0002] There are many kinds of shoes at present, and have various functions according to the difference of purpose and applicable ground, for example: keep warm, ventilate, wear-resisting, non-slip, light and so on. Among them, anti-slip is particularly important as the basic requirement of the sole, which can effectively protect the user from slipping. Especially for humid and oily working environments such as hull decks and kitchens, the excellent anti-skid performance is the safety guarantee for users. Common sole materials include rubber, PU, ​​EVA, TPR, etc. Among them, rubber shoe materials are soft and shock-resistant. [0003] The Chinese patent with the notification number CN106750584B discloses a method for compounding and modifying natural rubber masterbatch with lignin silica. The method uses...
