Abstract

The invention relates to the field of shoe making, in particular to a rubber for manufacturing soles and a preparation method thereof. The novel high abrasion-resistant rubber for the soles is prepared from the following raw materials in part by weight: 5 to 20 parts of styrene butadiene rubber (SBR), 70 to 100 parts of butadiene rubber (BR), 35 to 55 parts of white carbon black, 5 to 8 parts of naphthenic oil, 3 to 6 parts of active agent, 4 to 7 parts of zinc oxide, 0.8 to 1.5 parts of stearic acid, 2 to 3 parts of accelerant, 0.4 to 0.6 parts of antifogging agent and 2 to 3 parts of sulfur. Compared with the prior art, the high abrasion-resistant rubber has remarkable advantage of abrasion resistance compared with the traditional rubber for the soles.

Description

[0001] technical field [0002] The invention relates to the field of shoemaking, in particular to a rubber used for making shoe soles and a preparation method thereof. Background technique [0003] Shoes are requisite daily necessities in people's daily life. The comfort and service life of shoes are largely related to the material and performance of the sole. The material of the sole is currently in the majority of rubber soles. Such as ordinary rubber bottom, hot compression molding, divided into natural rubber and recycled rubber. Although it has good wear resistance, non-slip, elastic, not easy to break, good softness, good extensibility, stable shrinkage, good hardness, good bendability, and waterproof. But the disadvantages are heavy weight, easy to spit frost, not easy to corrode; not hard, easy to be pierced; poor air permeability and hygroscopicity, afraid of oil soaking, so it is not suitable to wear in places exposed to oil such as automobile gas stations. At...
