摘　　要：研究了高速纺丝油剂用EO/PO无规聚醚的合成方法。EO/PO无规聚醚的相对分子质量不同,其黏度、表面张力、摩擦系数等均不相同,综合分析认为聚醚最合适的相对分子质量应为3 000左右;聚醚的相对分子质量分布与油剂的稳定性关系密切,相对分子质量分布应越小越好。EO/PO值会影响聚醚的黏度、凝点、溶解性等性能,综合考虑各种性能,其比值以3为宜。此外,使用自制的聚醚作为主要平滑剂调配出锦纶6帘子线油剂,工业应用实验取得了满意的效果。The synthesis of EO/PO atactic polyether for high-speed spinning finish is studied.The viscosity,surface tension and friction coefficient of EO/PO atactic polyether varied with the different of its molecular weight,which is appropriate in 3 000 around.The molecular weight distributing of polyether is related tight with the stability of spin-finishes,and the polyether with little distributing will make the better stability of the finishes.The value of EO/PO will affect the viscosity,solidifying point and dissolution of the polyether,which is appropriate in 3 around.Moreover,PA6 tire cord spin-finishes are prepared using homemade polyether as main smoothness additive,whose effect of industry application test is satisfactory.
