Problems solved by technology

However, when the rubber sole works in an extremely cold environment, various physical indicators such as flexibility will be seriously reduced. When the temperature drops to a certain level, it may even cause the sole to break, and the wear resistance and elasticity are poor, and the wearing life short

Abstract

The invention relates to an extreme-cold-resistant high-elasticity wear-resistant rubber sole prepared from the following two parts of raw materials, wherein the first part is prepared from the following raw materials in parts by weight: 31.50-33.67 parts of natural rubber, 20.64-22.81 parts of butadiene rubber, 2.65-2.78 parts of zinc oxide, 1.58-1.68 parts of octadecanoic acid, 0.54-0.65 part of N-isopropyl-N'-phenyl-p-phenylenediamine, 0.56-0.76 part of 2,2,4-trimethyl-1,2-dihydro-quinoline, 26.06-28.24 parts of a reinforcing agent, 1.60-1.68 parts of coumarone resin and 9.23-10.33 parts of a softening agent; and the second part is formed by adding sulfur, an accelerant DM, an accelerant CZ and an accelerant D on the basis of the first part. The rubber sole keeps the toughness and cannot break at the temperature of 58 DEG C below zero and has good wear resistance.

Description

technical field [0001] The invention belongs to the technical field of footwear, and in particular relates to an extremely cold-resistant, highly elastic and wear-resistant rubber sole. Background technique [0002] At present, most of the various shoe soles are made of natural rubber as the raw material. After masticating and mixing with other ingredients to make rubber shoe soles, the cost is relatively controllable, and the hardness and other properties can be adjusted according to needs. Basically, People's requests have been met. However, when the rubber sole works in an extremely cold environment, various physical indicators such as flexibility will be severely reduced. When the temperature drops to a certain level, it may even cause the sole to break, and the wear resistance and elasticity are poor, and the wearing life short. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an ext...
