Problems solved by technology

In this application, the content of nitrile rubber is too high, and the processing technology is poor. The main direction of protection is oil resistance and antistatic, not oil and cold resistance. For non-antistatic rubber materials, it is absolutely unnecessary to use carbon black with good conductivity, etc.

Embodiment 1

[0069] Example 1 An oil-resistant and cold-resistant double-density shoe rubber outsole and its preparation method

[0070] This embodiment provides an oil-resistant and cold-resistant double-density rubber outsole for shoes and boots and its preparation method. The specific preparation process is carried out in sequence as follows:

[0071] (11) Rubber mastication

[0072] Put 31kg of natural rubber (model SCR-10) into an open mill or an internal mixer for masticating, and after the plasticity reaches 0.45-0.50, natural rubber A1 with satisfactory plasticity is obtained;

[0073] (12) Compounding and refining

[0074] Put 27kg of butadiene rubber (model BR9000) and 43 kg of nitrile rubber (model JSR N240S) into the open mixer or internal mixer together with A1 and knead until the rubber cross-section is uniform , after being flat and smooth, C1 is obtained;

[0075] (13) Compound mixing

Abstract

The invention discloses an oil-resistant and cold-resistant double-density rubber outsole for shoes and boots. The compatibility of raw materials is reasonable, and natural rubber, butadiene rubber and nitrile rubber are used as main materials, supplemented by other auxiliary agents, and the ingredients are processed in consideration of rubber materials. and physical and chemical properties, the oil resistance and cold resistance of the rubber material are good; The steps of manufacturing and the like are carried out in sequence, the method is simple, the process is easy to control, and the outsole of the prepared shoe has moderate hardness, good durability and cold resistance. The invention is suitable for preparing oil-resistant and cold-resistant rubber outsoles, rubber hoses, sealing rings and other rubber articles for shoes and boots.

Description

technical field [0001] The invention belongs to the field of rubber manufacturing, and relates to shoe rubber and a preparation method thereof, in particular to an oil-resistant and cold-resistant double-density shoe rubber outsole and a preparation method thereof. Background technique [0002] When working or training in cold regions and environments exposed to non-polar solvents, officers and soldiers need to wear cold-resistant and oil-resistant shoes. Due to their special functions, these shoes are very different from ordinary rubber shoes in the preparation process. Big difference. Rubber has cold resistance, which requires the main part of the rubber to have a soft molecular chain, which is not easy to be crystallized and hardened by the low temperature environment. At present, oil-resistant and cold-resistant rubber materials are mainly made of nitrile rubber, supplemented by a certain proportion of other rubber types. Nitrile rubber contains -CN groups and has stron...
