Embodiment approach

[0019] In one embodiment, the following materials are prepared in parts by weight: 10-20 parts of natural rubber, 80-90 parts of synthetic rubber, 10-20 parts of white carbon black, 1.5-2.5 parts of sulfur, 4-5 parts of active agent, and 1.8-2.5 parts of anti-aging agent, 1.5-2.5 parts of zinc oxide, 1.0-1.5 parts of stearic acid, 0.3-0.8 parts of anti-fogging agent, 1-1.5 parts of anti-aging agent, 40-50 parts of EVA and light resin.

[0020] Concrete preparation steps are as follows:

[0021] Step 1: Mix 10-20 parts by weight of natural rubber in the internal mixer for 5 minutes, turn on the rollers and start kneading for 5 minutes and masticate to obtain plasticized rubber, park for more than 20 hours, and cut the rubber;

[0022] Step 2: On the basis of step 1, sequentially add 80-90 parts by weight of synthetic rubber, 10-20 parts by weight of white carbon black, and 4-5 parts by weight of active agent for banburying, and the time is 4-5 minutes;

[0023] Step 3: On the ...

Abstract

The invention relates to light rubber for a sole and a preparation method thereof. The rubber comprises, by weight, 10-20 parts of natural rubber, 80-90 parts of synthetic rubber, 10-20 parts of white carbon black, 1.5-2.5 parts of sulfur, 4-5 parts of activators, 1.8-2.5 parts of accelerators, 1.5-2.5 parts of zinc oxide, 1-1.5 part of stearic acid, 0.3-0.8 part of an antifoggant, 1-1.5 parts of age resisters, 40-50 parts of ethylene-vinyl acetate copolymer (EVA) and 40-50 parts of light resin. The raw materials are subjected to banburying treatment and placed into a mold for high-temperature press vulcanization to produce the light rubber. The light rubber for the sole is scientific in formula, low in cost and simple in preparation process; and the sole weight is reduced effectively, and a wearer can feel comfortable during walking.

Description

technical field [0001] The invention relates to the field of shoe materials, in particular to a lightweight rubber used for shoe soles and a preparation method thereof. Background technique [0002] The sole is an important part of the shoe material field. The main function of the sole is to protect the feet, prevent slipping, shock absorption, ensure the comfort of the wearer's feet, and reduce the chance of sports injuries. [0003] The material of the sole is currently in the majority of rubber soles. Such as ordinary rubber bottom, thermoplastic 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 disadvantage is that it is easy to spit out, easy to be corroded and the biggest defect is that the quality is heavy. Contents of the invention [0004] Based on this, it is necessary ...
