Abstract

The well-known elastic polymeric material polyether urethane urea SKU-PFL, which is a typical segmented block copolymer, was chosen as an object of study. Powdered microdispersed fillers capable of improving wear resistance were added to this material at the manufacturing stage in different amounts (up to 1.5 wt %): calcium stearate and molybdenum disulfide. The found level of the optimal filler concentration for the studied elastomers in the region close to 0.5 wt % makes it possible to consider calcium stearate and molybdenum disulfide as not only effective, but also economical, components of promising wear-resistant polymeric materials.

填料对分段聚氨酯脲磨粒磨损的影响

摘要

著名的弹性聚合物材料聚醚氨基甲酸酯脲 SKU-PFL 是一种典型的嵌段共聚物，被选为研究对象。能够提高耐磨性的粉状微分散填料在制造阶段以不同的量（最多 1.5 重量％）添加到该材料中：硬脂酸钙和二硫化钼。所研究的弹性体的最佳填料浓度在接近 0.5 重量％的区域内发现的水平使得可以将硬脂酸钙和二硫化钼视为不仅有效而且经济的有前途的耐磨聚合物材料的组成部分。
