A kind of safety shoe rubber sole and preparation method thereof

Abstract

The invention discloses a safety shoe rubber sole and a preparation method thereof, comprising the following components in parts by weight: 40 parts of nitrile rubber, 8-10 parts of natural rubber, 5-8 parts of bromobutyl rubber, and kneading type polyurethane elastic 8-15 parts of body, 10-25 parts of plasticized cork powder, 10-3 parts of plasticized leather powder, 8-15 parts of nano calcium carbonate, 5-8 parts of naphthenic oil, 15 parts of white carbon black, antioxidant RD 0.6 1.2 parts of polyethylene glycol PEG4000, 0.6 parts of diethylene glycol, 0.15 parts of polyethylene wax, 2.6 parts of yellow resin C9, 1.2 parts of zinc oxide, 0.6 parts of stearic acid, 0.5 parts of silane coupling agent, 1.2 parts of insoluble sulfur , 1.8 parts of vulcanization accelerator; under the premise of ensuring the hardness of the sole, the sole of the present invention is added with plasticized cork powder and plasticized leather powder with a polyhydroxy structure to increase the polarity of the surface of the sole, improve the grip of the sole, and increase the sole's effect on the atmosphere. adaptability to the environment.

Description

technical field [0001] The invention relates to the technical field of rubber soles, in particular to a rubber sole for safety shoes and a preparation method thereof. Background technique [0002] Rubber is a very important sole material with a huge amount. As an important indicator to measure the performance of rubber, the friction performance of rubber products, like other properties, can attract more and more attention. For shoe rubber, good slip resistance is one of the basic functions that rubber products for soles should have, and it is also an important indicator to measure the quality of footwear. The anti-slip performance of the sole refers to the anti-slip effect or grip of the sole on the ground. The quality of the anti-slip performance is directly related to the safety of the shoe when wearing it. [0003] The hardness of the sole material also affects the anti-skid performance of the sole. Generally speaking, the hardness of the sole material is small, and when...
