preparation example Construction

[0062] The present invention also provides a preparation method of the composite rubber, comprising: mixing foamed rubber particles with non-foamed rubber particles, molding and vulcanizing to obtain composite rubber.

[0063] The foamed rubber particles are prepared according to the following method: 50-60 PHR of chlorinated polyethylene, 25-35 PHR of high-cis polybutadiene, 10-15 PHR of epoxy natural rubber, 10-20 PHR of white carbon black, 1-20 PHR of the first dispersant 3PHR; zinc oxide 2~5PHR, polyol 2~5PHR; magnesium oxide 2~5PHR; first silane coupling agent 1~3PHR, rubber activator 0.5~2PHR, first antiaging agent 0.5~2PHR, first anti-fog 0.5-2PHR of the agent, 0.5-1.5PHR of the first accelerator and 2-5PHR of the low-temperature foaming agent are mixed, molded and foamed to obtain foamed rubber particles.

[0064] Among them, the chlorinated polyethylene, high cis polybutadiene, epoxy natural rubber, white carbon black, the first dispersant, zinc oxide, polyol, magnesi...

Embodiment 1

[0073] Foam rubber raw material:

[0074]

[0075]

[0076] Mix the raw materials of the above-mentioned foam rubber at 165°C and 150kg / cm 2 Molding and foaming for 270s to obtain foamed rubber particles.

[0077] Non-foaming rubber raw material

[0078]

[0079] Mix the above non-foaming rubber raw materials at 165°C, 150kg / cm 2 Molded for 270s to obtain non-foaming rubber particles.

[0080] Mix foamed rubber particles (blue) and non-foamed rubber particles (red) according to the mass ratio of 30:70, 160°C, 150kg / cm 2 Forming and vulcanizing for 270s to obtain composite rubber.

[0081] figure 1 It is a photograph of the composite rubber obtained in Example 1.

[0082] Composite rubber molding preparation obtained in embodiment 1 figure 2 The sole of the pattern shown, in which the toe of the sole is thin horizontal stripes, the width of the stripes and the width between the stripes are both 0.5mm, and the depth of the stripes is 0.5mm; The width of the gro...

Embodiment 2

[0089] The preparation method is the same as in Example 1, except that foamed rubber particles and non-foamed rubber particles are mixed according to the mass ratio of 20:80.

[0090] The properties of the composite rubber obtained in Example 2 were tested, and the results obtained are shown in Table 2.

Abstract

The invention provides composite rubber. The composite rubber is obtained by compounding foamed rubber and non-foamed rubber. Compared with the prior art, the composite rubber disclosed by the invention has the advantages that excellent wet-skid property of the foamed rubber is matched with the wear resistance of the non-foamed rubber, so that the composite rubber has excellent wet-skid property on the premise of not influencing the wear resistance, and meanwhile, different conventional uneven appearance effects are shown.

Description

technical field [0001] The invention belongs to the field of material technology, and in particular relates to a composite rubber, a preparation method thereof and a shoe sole material. Background technique [0002] The slip resistance of the sole directly affects the comfort and safety of the shoes when they are worn. Poor anti-slip performance, easy to slip and fall when walking, especially on wet, smooth and slippery roads. With the development of the global construction industry, especially the construction of public places, the building floors are becoming more and more high-end, gorgeous and magnificent, but most of them ignore the problem of anti-slip on the ground, resulting in frequent accidents of slipping and falling. [0003] In order to reduce the losses caused by slipping and falling accidents, more and more consumers, shoe production and importing countries have focused their attention on improving the slip resistance of shoe soles. At present, the research ...
