Embodiment 1

[0010] An ultra-light shoe sole material, prepared from the following raw materials in parts by weight: 35 parts of isoprene rubber, 35 parts of butadiene rubber, 20 parts of EVA foam material powder, 7 parts of fumed white carbon black, and 1.5 parts of nano zinc oxide , 2.5 parts of microporous physical foaming agent, 1.5 parts of anti-aging agent, and 1.5 parts of active agent.

[0011] It is formed by high temperature, high pressure, internal mixing and mixing vulcanizing machine.

Embodiment 2

[0013] An ultra-light shoe sole material, prepared from the following raw materials in parts by weight: 30 parts of isoprene rubber, 30 parts of butadiene rubber, 20 parts of EVA foam material powder, 5 parts of fumed white carbon black, and 1 part of nano-zinc oxide , 2 parts of microporous physical foaming agent, 1 part of anti-aging agent, and 1 part of active agent. It is formed by high temperature, high pressure, internal mixing and mixing vulcanizing machine.

Embodiment 3

[0015] An ultra-light shoe sole material, prepared from the following raw materials in parts by weight: 40 parts of isoprene rubber, 40 parts of butadiene rubber, 20 parts of EVA foam material powder, 8 parts of fumed white carbon black, and 2 parts of nano-zinc oxide , 3 parts of microporous physical foaming agent, 2 parts of anti-aging agent, 2 parts of active agent. It is formed by high temperature, high pressure, internal mixing and mixing vulcanizing machine.

Abstract

The invention discloses an ultralight sole material. The ultralight sole material is prepared from raw materials in parts by weight as follows: 30-40 parts of isoprene rubber, 30-40 parts of polybutadiene, 20 parts of an EVA (ethylene vinyl acetate copolymer) foaming material, 5-8 parts of fumed silica, 1-2 parts of nano-zinc oxide, 2-3 parts of a microporous physical foaming agent, 1-2 parts of an anti-aging agent and 1-2 parts of an active agent. By means of the characteristics that the volume density/ratio of the ultralight sole material is 0.95 or lower, the ultralight sole material floats on the water surface completely, the portability of the sole material is improved, the original wear resistance and non-slip performance of rubber can be guaranteed, and the resilience comfort is improved.

Description

technical field [0001] The invention relates to the technical field of shoe materials, in particular to an ultralight shoe sole material. Background technique [0002] Existing materials for making shoe soles are mainly ordinary rubber, TPR thermoplastic rubber, PU polymer polyurethane synthetic materials and the like. It has defects such as heavy weight, poor anti-slip performance, easy to break, poor elongation, and water resistance. Contents of the invention [0003] The object of the present invention is to provide an ultra-light shoe sole material to solve the above technical problems. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] An ultra-light shoe sole material, prepared from the following raw materials in parts by weight: 30-40 parts of isoprene rubber, 30-40 parts of butadiene rubber, 20 parts of EVA foam material powder, and 5-8 parts of fumed white carbon black , 1-2 parts of nano-zinc oxide, 2...
