Problems solved by technology

Although the current wear-resistant rubber for sports shoe soles has certain wear resistance, there are many deficiencies, such as poor elasticity and weather resistance, and the soles of sports shoes wear out quickly during repeated bouncing and running. The material is easy to age and lose its elasticity. In addition, the current wear-resistant rubber for sports shoe soles has a large shrinkage, uneven sheeting, and difficult control of sheet thickness. In the post-vulcanization process, due to the strong air tightness and poor fluidity of the material, Large shrinkage, poor exhaust and other factors, high defective rate, affect production efficiency
Therefore, existing wear-resistant rubber for sole of sports shoes and preparation method thereof still need to be further improved

[0030] The present invention simultaneously provides a preparation method of wear-resistant rubber for sports shoe soles, comprising the following steps:

[0031] 1) Weigh the following ingredients in parts by mass: 50-80 parts of butadiene rubber, 10-30 parts of epoxy natural rubber, 5-20 parts of hydrogenated nitrile rubber, 1-2 parts of leveling agent, 2-5 parts of silane coupling agent 20-50 parts of white carbon black, 5-15 parts of nano-alumina, 2-5 parts of zinc oxide powder, 2-5 parts of polyethylene glycol, 0.5-2 parts of zinc stearate, 0.5-2 parts of water-based tackifying resin 2-5 parts of softening oil, 1-3 parts of anti-aging agent, 0.5-1 part of paraffin;

[0032] 2) Pour all the ingredients weighed in step 1) into the internal mixer for mixing, the mixing time is 7-9 minutes, and the temperature is 120-140°C;

[0033] 3) discharging, discharging, and cooling the mixture obtained in step 2);

[0034] 4) Weigh the following components by mass parts: 1.5-2 parts...

Embodiment 2

[0041] In Example 2, the mixing time in step 2) is 7 minutes, and the temperature is 120-140°C; the mixing time in step 5) is 5 minutes, and the temperature is 50-70°C;

Embodiment 3

[0042]In Example 3, the mixing time in step 2) is 8 minutes, and the temperature is 120-140°C; the mixing time in step 5) is 4 minutes, and the temperature is 50-70°C.

[0043] The wear-resistant rubber for sports shoe soles prepared in the above-mentioned Examples 1, 2 and 3 was tested for performance, and compared with the performance of existing products at the same time, the results are shown in Table 2 below.

Abstract

The invention discloses wear-resistant rubber for sports shoe soles. The wear-resistant rubber for the sports shoe soles comprises the following components in parts by mass: 50-80 parts of butadiene rubber, 10-30 parts of epoxy natural rubber, 5-20 parts of hydrogenated butadiene-acrylonitrile rubber, 1-2 parts of a homogenizing agent, 2-5 parts of a silane coupling agent, 25-65 parts of a reinforcing agent, 2-5 parts of zinc oxide powder, 2-5 parts of polyethylene glycol, 0.5-2 parts of zinc stearate, 1.5-2 parts of a vulcanizing agent, 1.6-2.1 parts of an accelerator, 0.5-2 parts of a tackifier, 2-5 parts of a softening oil, 1-3 parts of an anti-aging agent and 0.5-1 part of paraffin. The invention further provides a preparation method of the wear-resistant rubber for the sports shoe soles. Wear-resistant rubber shoe soles for the sports shoe soles, prepared according to the technical scheme adopted by the invention, have super wear resistance which is incomparable with that of ordinary rubber soles, and have many properties such as good weather resistance and folding resistance; the preparation method is simple in production process and is suitable for wide application.

Description

technical field [0001] The invention relates to the field of materials, in particular to a wear-resistant rubber for sports shoe soles and a preparation method thereof. Background technique [0002] Due to its special purpose, sports shoes require its sole rubber to have wear resistance, good folding resistance and weather resistance. Although the current wear-resistant rubber for sports shoe soles has certain wear resistance, there are many deficiencies, such as poor elasticity and weather resistance, and the soles of sports shoes wear out quickly during repeated bouncing and running. The material is easy to age and lose its elasticity. In addition, the current wear-resistant rubber for sports shoe soles has a large shrinkage, uneven sheeting, and difficult control of sheet thickness. In the post-vulcanization process, due to the strong air tightness and poor fluidity of the material, Due to factors such as large shrinkage and poor exhaust, the rate of defective products i...
