兖州矿业(集团)公司杨村煤矿开展了在矿山提升绞车上应用新材料绳衬的研究,并且研制出了高耐磨聚氨酯绳衬。他们利用分子量为1000的国产聚酯多元醇、进口TDI-100、国产MO-CA及国产抗静电剂和阻燃剂,制备聚氨酯矿山提升绞车绳衬。聚氨酯试片拉伸性能测试结果表明,其拉伸强度、拉断伸长率、扯断永久变形和磨耗量均优于在相同场所应用的橡 Yancun Mining (Group) Company Yangcun Coal Mine carried out in the mine hoist application of new materials on the rope lining research, and developed a high wear-resistant polyurethane rope lining. They made use of domestic polyester polyol with molecular weight of 1000, import TDI-100, domestic MO-CA and domestic antistatic agents and flame retardants to prepare polyurethane mine hoist rope lining. Tensile properties of the polyurethane test piece test results show that its tensile strength, elongation at break, permanent deformation and tear wear are better than in the same place of application of rubber
