Abstract
The invention discloses a low-density microcellular polyurethane wear-resisting sole material. The low-density microcellular polyurethane wear-resisting sole material is prepared from the following components in parts by weight: 100 parts of polyester polyol, 5 to 20 parts of diol chain extender, 0.5 to 1.2 parts of silicone surfactant, 0.3 to 1.0 part of tertiary amine catalyst, 0 to 0.5 part of metal catalyst, 5 to 10 parts of graphene fiber and 2 to 5 parts of tungsten-cobalt carbide hard alloy particles. According to the material, the defect of plastic feeling caused by reduction of the density of a backing material of an ordinary sole is improved, and light weight is improved while the wear resistance can be improved.
Description
technical field [0001] The invention relates to the technical field of shoe sole materials, in particular to a low-density microporous polyurethane wear-resistant shoe sole material. Background technique [0002] The structure of the sole is quite complex. In a broad sense, it can include all the materials that make up the bottom, such as the outsole, midsole and heel. In a narrow sense, it only refers to the outsole. The common characteristics of general sole materials should be wear-resistant, water-resistant, oil-resistant, heat-resistant, pressure-resistant, impact-resistant, good elasticity, easy to fit the shape of the foot, and not easy to change after being shaped. Heat preservation, easy to absorb moisture, etc., and at the same time, it must cooperate with the midsole, which has a braking effect when walking and changing feet, so that it will not slip and is easy to stop. There are many types of sole materials, which can be divided into natural base materials and ...
