Problems solved by technology

[0004] PA, the name is polyamide, its foaming material has high mechanical strength, good toughness, excellent tensile and compressive properties, outstanding fatigue resistance, high softening point, smooth surface, corrosion resistance and other excellent properties, but its rigidity is relatively high. Poor, separate PA foam materials are rarely used in shoe materials and other fields
[0005] Furthermore, as consumers' health awareness continues to increase, the selection of functional materials such as comfort and antibacterial has gradually become one of the important considerations for consumers, especially in the selection of shoe materials, which have mechanical properties, comfort, antibacterial It is very necessary. However, the current antibacterial shoe materials mainly use antibacterial upper materials, which are rarely used on sole materials. This is also one of the important directions for shoe material research and development.

Abstract

The invention relates to the technical field of shoe materials, in particular to a preparation method of an ultra-light shoe sole with a hydrogen explosion structure, the shoe sole and sneakers. The ultra-light shoe sole is prepared from the following raw materials in parts by mass: 60-70 parts of a polyurethane prepolymer, 3.5-7.5 parts of whiskers, 2.5-3.5 parts of a chain extender, 14-24 parts of antibacterial polyamide, 7-12 parts of a polysiloxane-polyimide block copolymer, 1.5-2.1 parts of a nucleating agent and 1.5-1.8 parts of a cross-linking agent. The TPU and the PA are compounded, the composite material is prepared through a supercritical foaming process, and the composite material is mainly applied to a midsole of a shoe sole. The mechanical strength and toughness of the composite material are further enhanced by adding whiskers into the TPU, the shoe sole has certain antibacterial property by adding antibacterial modified PA, and the sneakers with the shoe sole are excellent in durability and elasticity.

Description

technical field [0001] The invention relates to the technical field of shoe materials, in particular to a method for preparing an ultra-light shoe sole with a hydrogen explosion structure, a shoe sole and sports shoes. Background technique [0002] TPU, named thermoplastic polyurethane elastomer rubber, is mainly divided into polyester type and polyether type. It has a wide range of hardness (60HA-85HD), wear resistance, oil resistance, transparency, and good elasticity. It is widely used in daily necessities, sporting goods, toys, decorations, etc. The main features that are widely used in materials and other fields are: wide range of hardness: by changing the ratio of the reactive components of TPU, products with different hardness can be obtained, and with the increase of hardness, the products still maintain good elasticity and wear resistance High mechanical strength: TPU products have outstanding bearing capacity, impact resistance and shock absorption performance; out...
