[0085] Preparation Example 1: Preparation of Vulcanized Rubber

[0086] First mixing:

[0087] Put the main rubber into the internal mixer, set the rotational speed of the internal mixer to 80rpm, and set the mastication temperature of the internal mixer to perform mastication to obtain the masticated rubber. Then, white carbon black, additives and surface modifiers are added into the internal mixer, the mixing temperature of the internal mixer is set, and the first mixing is performed with the masticated rubber to obtain the first mixed rubber.

[0088] Second mixing:

[0089] Lift the top pin of the internal mixer for the first mixing, carry out the second mixing with zinc methacrylate, hydrogenated terpene resin, activator, anti-aging agent, softener and the first mixing rubber, and deglue, Stand for 4h to obtain the second rubber compound.

[0090] The third mixing:

[0091] Put the aforementioned second compounded rubber in the internal mixer for mastication, set the ...

[0095] Second mixing:

[0096] Put the main rubber into the internal mixer, set the rotational speed of the internal mixer to 80rpm, and set the mastication temperature of the internal mixer to perform mastication to obtain the masticated rubber. Then add white carbon black, additives, surface modifiers, zinc methacrylate, hydrogenated terpene resins, activators, anti-aging agents and softeners into the internal mixer, set the mixing temperature of the internal mixer, and plasticize The rubber is subjected to the second mixing to obtain the second mixed rubber.

[0097] The third mixing:

[0098] Put the aforementioned second compounded rubber in the internal mixer for mastication, set the speed of the internal mixer to 80rpm, and the initial plasticating temperature of the internal mixer to 40°C, after the second compounded rubber is masticated for 1min, add The vulcanizing agent and auxiliary crosslinking agent are mixed for the third time to obtain the final compound rubb...

Abstract

The invention relates to the field of rubber, and discloses a rubber composition for shoe soles, application of the rubber composition, vulcanized rubber and a preparation method and application of the vulcanized rubber. The rubber composition comprises main rubber, white carbon black, zinc methacrylate, a surface modifier, hydrogenated terpene resin, an activating agent, a softening agent, a vulcanizing agent, an assistant crosslinker, an anti-aging agent and an additive, the main body rubber is a combination of butadiene styrene rubber and ethylene propylene diene monomer, the additive is calcium sulfate whisker or anhydrite, and the vulcanizing agent is a peroxide vulcanizing agent. The vulcanized rubber prepared from the rubber composition provided by the invention has relatively high tensile strength, wear resistance and flexing resistance.

Description

technical field [0001] The invention relates to the field of rubber, in particular to a rubber composition for shoe soles and its application, a method for preparing vulcanized rubber, and the vulcanized rubber prepared by the method and the application of the vulcanized rubber in shoe soles. Background technique [0002] Shoes are the necessities of people's life, and the sole is an important factor affecting the quality of shoes. At present, the main materials of sole materials mainly include TPR, EVA, rubber, polyurethane, etc. [0003] In the prior art, white fillers are widely used in footwear products, especially in light-colored or colored products, which can endow the sole with good wear resistance, anti-skid performance and shoe surface adhesion performance, among which white carbon black is the most widely used , but the surface of silica contains polar groups, which has poor compatibility with rubber substrates and has an adverse effect on the performance of the ...
