摘要

热塑性聚氨酯(TPU)作为鞋底等材料最突出的问题是止滑性能不足，在湿环境和结冰环境下易打滑. 纳米填料引起材料表面微观形貌、材料变形能力的变化对抗湿滑有重要影响. 本研究将高乙烯基溶聚丁苯橡胶(HVSSBR)与TPU共混，探究了纳米二氧化硅(SiO

)填充的TPU/HVSSBR(70/30)复合材料中填料的选择性分散，并且采用LAT-100试验机测试了恒定面压下不同SiO

用量填充的TPU/HVSSBR复合材料在干、湿摩擦表面以及不同冰面温度(-20，-10和-5 ℃)下的摩擦性能. 结果表明，SiO

在TPU/HVSSBR共物中易分散于HVSSBR橡胶相中，造成了材料表面粗糙度和变形能力的差异，使得干摩擦系数下降13.9%，湿摩擦系数提升8.7%；3种冰面温度(-20，-10和-5 ℃)下摩擦系数最大提升幅度分别为16.9%，17.5%，21.2%. SiO

的加入能提高材料在湿表面和冰表面上的摩擦系数，进一步改善了TPU止滑性能.

Abstract

The most prominent problem of thermoplastic polyurethane (TPU) as sole materials is that it has insufficient skid resistance and is easy to slip under humid or freezing environments. The changes of micro-morphology and deformation capacity of material surface caused by nano-fillers play an important role in the skid resistance. On the basis of blending high vinyl solution polymerized styrene butadiene rubber (HVSSBR) with TPU

the dispersion state of nano silica (SiO

) in TPU/HVSSBR (70/30) composites was investigated. And the friction properties of TPU/HVSSBR composites filled with different SiO

contents under constant surface pressure were tested by LAT-100 machine on dry

wet friction surfaces and ice surface of different temperatures (-20

-10 and 5 ℃). The results showed that SiO

was easily dispersed in HVSSBR rubber phase of TPU/HVSSBR blends

and the addition of SiO

caused the difference of surface roughness and deformation ability of the material surface

resulting in the decrease of dry friction coefficient by 13.9%

the increase of wet friction coefficient by 8.7%; the maximum increase of friction coefficient at three kinds of ice surface temperatures (-20

-10 and -5 ℃) were 16.9%

17.5% and 21.2% respectively. It is indicated that the addition of SiO

can improve the friction coefficient of the material on smooth wet and ice surface and further improve the skid resistance of TPU.
