超高分子量聚乙烯填料改性研究

Study on the properties of UHMW PE modiified by the Fillers

本文选用粉煤灰、硅藻土和石墨三种无机填料填充超高分子量聚乙烯（ＵＨＭＷ－ＰＥ），考察了填料对其性能的影响。结果表明，填为加适量的粉煤灰可使ＵＨＭＷ－ＰＥ的耐磨性提高约５０％，热变形温度提高达３０℃。填充三种填料后，冲击强度都有所下降，但当含量控制在１５％以内时，还具有较高的低温冲击性能。

\ This paper discusses effects of three fillers of fly ash, diatomite and graphite on properties of filled UHMW PE. The results show that wear loss of the composites are decreased about 50% and the thermal deformation temperature are increased about 30℃. Notch impact strength of the all three filled UHMW PEs decreases, when the filler content is less than about 15 volume percent, the low temperature impact strength is still maintained high.
