Abstract

The invention discloses a conductive polyurethane sole material which comprises the following components in percentage by weight: 30-45% of polyhydric alcohol, 4-9% of a chain extender, 0.03-2% of a catalyst, 0.09-0.3% of a foamer, 0.05-2% of a foam stabilizer, 3-10% of plasticizer, 30-45% of prepolymer, 0.5-5% of graphite and 1-8% of aluminum borate crystal whiskers. The conductive performance of the polyurethane shoe material can be extremely improved by adding graphite and aluminum borate crystal whiskers. The affinity of graphite and aluminum borate crystal whiskers to the polymer is improved by surface pretreatment for graphite and aluminum borate crystal whiskers through a coupler. The toughness of the polyurethane material is not reduced to a great extent due to the addition of the inorganic conductive component by adding the plasticizer. In addition, the conductive polyurethane sole material disclosed by the invention is simple in process and environment-friendly.

Description

Technical field: [0001] The invention relates to the technical field of shoe materials, in particular to a polyurethane shoe sole material. Background technique: [0002] There are many types of sole materials, which are generally divided into two types: natural sole materials and synthetic sole materials. Natural sole materials include natural bottom leather, bamboo, wood, etc. Synthetic sole materials include rubber, ethylene vinyl acetate EVA, polyurethane PU, polyvinyl chloride PVC, etc. The common characteristics of sole materials are wear resistance, water resistance, good elasticity, easy to fit the foot shape, and not easy to deform after being shaped. Synthetic sole materials are currently the most widely used type of shoe materials. [0003] Polyurethane sole material, as a kind of synthetic shoe material, is more and more popular among consumers due to its characteristics of lightness, wear resistance, good elasticity, anti-skid and oil resistance, and comfortab...
