Abstract

The invention relates to a polyurethane shoe sole and a preparation method thereof. The polyurethane shoe sole comprises a component A and a component B, wherein the component A comprises the following raw materials in parts by mass: 70 to 75 parts of two-functionality-degree polyether polyol, 2 to 4 parts of four-functionality-degree polyol, 10 to 12 pars of three-functionality-degree polymer polyol, 0.4 to 0.5 part of water, 6 parts of glycerol, 2 parts of 2-hydroxy-4-octyloxybenzophenone and 3 to 5 pars of an anti-static agent; the component B comprises 110 parts by mass of MDI-polyester prepolymer. The polyurethane shoe sol is non-toxic, environment-friendly, portable and wear-resistant, and has anti-static, earthing and free electronic double-way breakover effects. Static electricity generated by a human body can be guided into the ground, the ground negative electrons are guided into the body, and the effect of balancing yin and yang in the traditional Chinese medicine is achieved.

Description

technical field [0001] The invention belongs to the technical field of polyurethane materials, and in particular relates to a polyurethane shoe sole and a preparation method thereof. Background technique [0002] As a new type of polymer material, polyurethane is a high-tech, high-performance, and high-value-added product. As a sole material, it is oil-resistant, soft, wear-resistant, lightweight overall, and has warmth and comfort. However, the existing polyurethane sole is insulated, and sweat cannot be discharged, the feet are prone to heat and static electricity is produced, which has adverse effects on human health. [0003] The air is dry in autumn and winter, and people are often injured by static electricity. The invention discloses a shoe sole, which can lead the static electricity on the body into the ground and the free electrons from the earth into the body on the ordinary ground. Most of the human body is composed of water and minerals, which are good conducto...
