Embodiment approach

[0106] Ultra-high wear-resistant rubber sole formula: 65 kg of natural rubber, 35 kg of synthetic rubber, vulcanizing agent: 1.9 kg of sulfur, 1.5 kg of vulcanization accelerator M, vulcanization active agent: 3 kg of zinc oxide and 3 kg of stearic acid, solid softener : Coumarone 2 kg, liquid softener: softening oil 12 kg, carbon black 60 kg, antioxidant 4010NA 1.5 kg and release agent LGM-A 0.4 kg.

[0107] The preparation method of super high wear-resistant rubber sole:

[0108] (1) Mastication: Take natural rubber and refine it until the Vickers plasticity is 0.5 to obtain plastication rubber;

[0109] (2) Master batching: 25 kg of carbon black, synthetic rubber, solid softener and 6 kg of liquid softener are added to the internal mixer for master batching to obtain A product;

[0110] (3) Mixing: Put A product and the plasticized rubber obtained in (1) into a rubber mixer and refine for 0.5 minutes under the conditions of 100°C and 0.39-0.40MPa, then add the remaining ca...

Abstract

The invention discloses a highly wear resistant rubber sole and a preparation method thereof. The rubber sole is mainly made by plastication, masterbatching, mixing and remixing of natural rubber, synthetic rubber, sulfidizer, vulcanization accelerator, vulcanization activator, solid softener, liquid softener and carbon black. The rubber sole has the advantages of enhancing the outside force resistance of the rubber, improving the extension modulus and the tensile strength of the rubber, improving the resilience force of the outer bottom, lowering the Hardness HA of rubber materials and radically realizing the highly wear resistant performance; moreover, in the invention, the rubber materials for the highly wear resistant rubber sole are not mixed with plastic materials, and the weight of the synthetic rubber against the total weight of framework materials is not more than 40 percent, while the wear resistance of the sole reaches the Akron wear volume 0.15 to 0.30cm<3>/1.61km, which is far higher than the wear resistance (0.5cm<3>/1.61km) of the rubber for tires, so that the service life of the rubber sole is prolonged more than three times.

Description

technical field [0001] The invention relates to the technical field of shoemaking, in particular to an ultra-high wear-resistant rubber sole and a preparation method thereof. Background technique [0002] Under normal circumstances, the wear resistance of the rubber outsole of the rubber shoes is about 1.0-2.0cm of Akron wear volume. 3 Between / 1.61km, this kind of wear resistance can only make the rubber shoes meet the requirements of general wearing. Due to the influence of factors such as rubber aging, production conditions and limitations of the manufacturing process, the service life of the rubber sole is not long. [0003] Automobile tires, which are also rubber products, have relatively high requirements for wear resistance, and their wear resistance requirements can reach Acron wear volume not greater than 0.50cm 3 / 1.61km, but the production conditions of automobile tires and rubber shoes are different, tires are one-time vulcanized products, the external condition...
