Abstract

The invention discloses a wear-resistant hard rubber sole suitable for a boot heel. The wear-resistant hard rubber sole is prepared from the following two portions of raw materials, wherein a first portion is prepared from the following raw materials: hydrogenated butadiene-acrylonitrile rubber, rubber-plastic alloy, zinc oxide, octadecanoic acid, magnesium oxide, N-isopropyl-N'-phenyl p-phenylenediamine, 2,2,4-trimethyl-1,2-dihydroquinoline, resin, fumed silica, polyethylene glycol, and dioctyl phthalate; and a second portion is a mixture of sulfur, an accelerant TMTD and an accelerant DM onthe basis of the charging amount of the first portion per kilogram. By adopting the wear-resistant hard rubber sole provided by the invention, the characteristics of the rubber sole such as tear resistance and wear resistance can be apparently improved, the surface hardness of the rubber can be improved, the scratch can be resisted, and the wear resistance of the material can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of rubber soles, and in particular relates to a wear-resistant hard rubber sole suitable for heels of shoes and a preparation method thereof. Background technique [0002] Rubber soles are generally made of natural rubber as a raw material, after mastication, plus other ingredients for mixing and refining to make rubber soles. Its wear performance is poor, especially for outdoor shoes, and its wearing life is short. Under normal circumstances, the wear of the rubber sole is mainly due to the repeated compression and deformation of the surface layer and the heat generated by the friction between the rubber sole and the object, as well as the cracking of the rubber structure of the rubber sole due to factors such as oil stains and ozone oxidation on the rubber sole. The rubber is separated from the surface layer, and the rubber sole is not wear-resistant. Due to the state of the person walking and the weight ...
