Problems solved by technology

Although alloy particles increase the wear resistance of the sole, their weight is relatively large, which is contrary to the goal of lightweighting the shoe, so its application is greatly restricted

Abstract

The invention discloses a high-polymerization-degree polyvinyl chloride wear-resistant sole material. The sole material is prepared from, by weight, 100 parts of HPVC (high-polymerization-degree polyvinyl chloride), 10-20 parts of nitrile butadiene rubber, 40-60 parts of dioctyl phthalate, 10-20 parts of white carbon black, 5-15 parts of calcium carbonate filler, 5-10 parts of graphene and 2-5 parts of tungsten-cobalt carbide hard alloy particles. The high-polymerization-degree polyvinyl chloride wear-resistant sole material can improve wear resistance and can realize light weight, tensile strength is greater than 20MPa, elongation at break is greater than 370%, abrasion loss is smaller than 0.15cm<2> / 2km, stripping strength is greater than 4.8kN / m, and breaking strength is greater than 47kN / m.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a high-polymerization-degree polyvinyl chloride 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 synthetic base m...
