Abstract

The invention relates to a polyurethane shoe sole added with graphene composite materials and a preparation method thereof. The polyurethane shoe sole is divided into an upper layer and a lower layer,the upper layer is a graphene conductive layer, and the lower layer is a polyurethane supporting layer; the polyurethane supporting layer is prepared from, by mass, a group A and a group B, wherein the group A comprises 70-75 parts of two-functionality-degree polyether polyol, 2-4 parts of four-functionality-degree polyhydric alcohols, 10-12 parts of three-functionality-degree polymer polyhydricalcohols, 0.4-0.5 part of water, 6 parts of glycerol, 2 parts of 2-hydroxy-4-(octyloxy)benzophenone and 3-5 parts of anti-static agents; the group B comprises 110 parts of MDI-polyester prepolymer. The prepared polyurethane shoe sole added with the graphene composite materials has the advantages of being free of poison, environmentally friendly, light and endurable to wear, and moreover, and has the functions of static electricity prevention, ground air injection and bidirectional conductibility, static electricity generated by the human body can be conducted into the ground, the ground negative electrons can be conducted into the human body, and therefore an effect of balancing the yin and yang in 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 added with a graphene composite material 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 soles of leather shoes and sports shoes we wear every day are mostly insulated and short-circuited with the ground, so it is impossible to introduce static electricity into the ground to discharge the charge. Excessive static electricity accumulation in the human body will cause abnormal current conducti...
