High-elastic, high-toughness and environment-friendly rubber sole material and preparing method thereof

Abstract

The invention provides a high-elastic, high-toughness and environment-friendly rubber sole material. The sole material is prepared from, by weight, 45-52 parts of nitrile butadiene rubber, 15-20 parts of PVC, 0.5-1 part of an antifogging agent, 1-1.5 parts of an anti-ageing agent, 0.5-1 part of a coupling agent, 1.5-2.5 parts of a vulcanizing agent, 1.5-2 parts of an accelerator, 10-14 parts of a plasticizer, 3-5 parts of a foaming agent, 0.5-1 part of a cross-linking agent, 5 parts of zinc oxide powder, 3 parts of stearic acid and 18-24 parts of a composite carbon dust material. The invention further provides a preparing method of the high-elastic, high-toughness and environment-friendly rubber sole material. The sole material is good in elasticity and flexibility and environmentally friendly.

Description

Technical field:

[0001] The invention relates to a shoe sole material, in particular to a high-elasticity, high-toughness, environment-friendly rubber shoe sole material and a preparation method thereof. Background technique:

[0002] Nitrile rubber is produced by emulsion polymerization of butadiene and acrylonitrile, referred to as NBR. Nitrile rubber is mainly produced by low-temperature emulsion polymerization. It has excellent oil resistance, high wear resistance, good heat resistance, and good adhesion. powerful. Its disadvantages are poor low temperature resistance, poor ozone resistance, poor insulation performance, and slightly poor elasticity. There are five types of acrylonitrile content (%) in nitrile rubber: 42-46, 36-41, 31-35, 25-30, and 18-24. The higher the acrylonitrile content, the better the oil resistance, but the cold resistance will decrease accordingly, and it can be used for a long time in the air at 120°C or in the oil at 150°C. In addition, nitr...
