Abstract

The invention discloses a cork polyurethane sole material. The sole material comprises the following raw materials in parts by weight: 3-4 parts of azodicarbonamide, 30-35 parts of saw dust, 80-100 parts of polycarbonate diol, 60-70 parts of isophorone diisocyanate, 1-2 parts of an initiator, 0.5-1 part of a catalyst a, 0.1-0.2 part of color paste, 2-4 parts of trimethylamine and 20-30 parts of anelastic dispersion liquid. The sole material disclosed by the invention has very strong impact strength and elongation at break, and is soft in texture, good in wear resistance, low in cost and highin quality.

Description

technical field [0001] The invention belongs to the field of shoe sole materials, and in particular relates to a cork polyurethane shoe sole material and a preparation method thereof. Background technique [0002] Polyurethane is the abbreviation of polyurethane. It is a polymer compound containing many repeated amino groups on the polymer main chain. It is formed by chemical reaction between isocyanate and polyol compound. It is light, comfortable, cold-resistant, and processed Fast and many other advantages, and its physical and mechanical performance indicators can be changed within a certain range through the selection of raw materials and the adjustment of formula, so as to meet the different requirements of users for product performance; [0003] Because of many advantages such as low production cost of polyurethane, it is widely used in the making of shoe soles. However, the soft polyurethane sole has poor wear resistance and is not resistant to hydrolysis, which eas...
