Abstract

The invention provides an antistatic polyurethane shoe material which is prepared from the following components in parts by weight: 40-50 parts of polyether dibasic alcohol, 30-40 parts of tolyl-2,4-diisocyanate, 3-8 parts of chain extender, 2-6 parts of graphitized carbon black, 1-4 parts of crosslinking agent, 1-3 parts of coupling agent, 0.1-1 part of foaming agent and 0.2-1 part of catalyst. The invention also provides a manufacturing method of the antistatic polyurethane shoe material. The polyurethane shoe material provided by the invention has favorable antistatic property.

Description

Technical field: [0001] The invention relates to a shoe material, in particular to an antistatic polyurethane shoe material and a manufacturing method thereof. Background technique: [0002] Polyurethane is a polymer with many -NHCOO- in the main chain of the polymer structure. It is a synthetic material with a wide range of uses. Its industrial production is mainly prepared by the reaction of various polyols containing terminal hydroxyl groups and polyisocyanates. An important use of polyurethane is as a shoe material, which has the advantages of environmental protection, lightness, comfort and non-deformation, so it is favored by more and more people. However, ordinary polyurethane shoe material has a high resistance value, and cannot take away static electricity in the occasion where antistatic is required, so that it cannot be used in antistatic occasions. Invention content: [0003] The technical problem to be solved by the present invention is to provide an antistat...
