Abstract

The invention discloses a tear-resistant sole material and a manufacturing method thereof. The tear-resistant sole material comprises the following components in parts by weight: 55-65 parts of natural rubber; 35 to 45 parts of EPDM; 4-6 parts of a compatilizer; 40-50 parts of a filler, 3-4 parts of activated zinc oxide; 1.5 to 2 parts of stearic acid; 2-4 parts of a foaming agent; 2.5 to 3 partsof vulcanizing agent; 0.3 to 0.6 part of an accelerant; and 0.2 to 0.4 part of an anti-aging agent; a preparation process of the compatilizer comprises the following steps: mixing 10-12 parts by weight of brominated butyl rubber and 0.2-0.3 part by weight of BPO, heating to 60-70 DEG C, mixing for 15-20 minutes, adding 0.5-0.7 part by weight of octadecyltrimethoxysilane, heating to 110-120 DEG C,continuously mixing for 10-15 minutes, cooling, and discharging to obtain the compatilizer. The tear-resistant sole material can meetthe anti-skid requirements ofsoles ondry surfaces andwet surfaces,the quality far exceeds the national standard, and the prepared soles are good in tear resistance and wear-resistant compared with other types of anti-skid soles, and wearing durability is achieved.

Description

technical field [0001] The invention relates to shoe soles, in particular to a tear-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 have the best anti-skid performance. The rubber sole with good anti-skid performance is soft and has a high coefficient of friction, but its mechanical strength is relatively poor, and it is easy to wear and tea...
