Thermoplastic elastomer and preparation method therefor

Abstract

The invention provides a thermoplastic elastomer. The thermoplastic elastomer is prepared from the following raw materials in parts by weight: 33-40 parts of base oil, 35-45 parts of calcium powder with the grain size of 1,000 to 1,250 meshes, 15-20 parts of styrene-butadiene-styrene block copolymer, 15-20 parts of styrene-ethylene-butylene-styrene block copolymer, 1-3 parts of cyclohexane and 1-3 parts of polyurethane. The invention further provides a preparation method for the thermoplastic elastomer. The thermoplastic elastomer and the preparation method therefor have the beneficial effects that the cyclohexane and the polyurethane are added into the original thermoplastic elastomer formula according to certain proportions, so that the Akron attrition volume of prepared soles is lower than 0.6cm<3> / 1.61km, and the wear resistance is close to the requirements of automobile tires; the surface roughness of the thermoplastic elastomer is improved due to the polyurethane, so that the skid resistance is good; and the cyclohexane is highly volatile, so that a certain space is reserved for the free expansion of the thermoplastic elastomer, and the density is lowered while the resistance to temperature is improved.

Description

technical field [0001] The invention relates to a thermoplastic elastomer, in particular to a thermoplastic elastomer for making shoe soles and a preparation method thereof. Background technique [0002] The anti-skid performance of the sole refers to the anti-skid effect or grip of the sole on the ground. The quality of the anti-skid performance is directly related to the safety of the shoes when worn. The anti-skid performance of the soles is not good, and it is easy to slip and fall when walking on slippery and icy roads. In most parts of northern my country, the winter temperature is low, and the roads are more likely to accumulate ice, and people are more likely to slip when walking on them. In addition, with the prosperity and development of the economy and the continuous progress of the society, people make the road surface and indoor ground smoother and smoother, which leads to the frequent occurrence of fall accidents. Therefore, it is urgent to effectively improve ...

AI Technical Summary

Problems solved by technology

The anti-wear performance of the sole made of this thermoplastic elastomer is about 1.0-2.0 cm in the wear volume of Acron 3 Between / 1.61km, and the anti-slip performance is not good. On ice or smooth ground with water, the soles made of this material are very easy to slip, and accidents such as sole breakage are easy to occur when the ambient temperature is extremely low. , the wear resistance is not high, and sufficient stability, safety and comfort cannot be guaranteed
