Abstract

The invention discloses a sneaker sole with a good anti-skid effect and a preparation method thereof. The sneaker sole with the good anti-skid effect is prepared from the following raw materials in parts by weight: 35 to 45 parts of natural rubber, 18 to 26 parts of butadiene rubber, 25 to 35 parts of a polyurethane elastomer, 6 to 9 parts of glass fiber, 1 to 1.5 parts of nano zinc oxide, 3 to 5 parts of a heat stabilizer, 1.3 to 1.7 parts of a cross-linking agent and 1.8 to 2.5 parts of a foaming agent. According to the sports shoe sole with the good anti-skid effect, the raw materials are selected, the content of the raw materials is optimized, the advantages of the raw materials are brought into full play, and the raw materials supplement and promote each other, so that the prepared sports shoe sole with the good anti-skid effect (dry-type anti-skid and wet-type anti-skid) is high in anti-skid coefficient and good in anti-skid effect. The sports shoe sole is high in resilience rate, still high in resilience rate after being pressed, good in resilience performance, high in impact strength and tensile strength, good in comprehensive mechanical property, good in shock absorption performance, low in density (the density tested is 0.21-0.22 g / cm < 3 >) and good in portability.

Description

technical field [0001] The invention relates to the technical field of polymer composite foamed shoe sole materials, in particular to a sports shoe sole with good anti-skid effect and a preparation method thereof. Background technique [0002] Thermoplastic polyurethane elastomer (TPU) is a commonly used shoe sole material, which has many advantages: low density, soft texture, comfortable and light to wear; good dimensional stability, long storage life; excellent shock absorption and anti-skid performance; good temperature resistance ; Good chemical resistance and so on. [0003] Natural rubber is the variety with the best coordination of physical and mechanical properties and process performance among rubber materials. It has been widely used in daily life, medical and health care, transportation, agriculture, scientific experiments, national defense and other fields. With the development of society, people have put forward higher requirements on the performance of product...
