• Synergistically thickened water-based hydraulic or metal-working fluid
  申请人：BASF WYANDOTTE CORPORATION

  公开号：EP0061823A1

  公开（公告）日：1982-10-06

  Water-based hydraulic fluids and metalworking lubricants are disclosed which are thickened with a polyether polyol having a molecular weight of about 1000 to about 75,000 modified with an alpha-olefin epoxide having about 12 to about 18 carbon atoms. Unexpectedly, synergistic thickening results from a combination of said polyether polyol with the components of a water-based hydraulic fluid or metalworking lubricant. The particularly effective components of the hydraulic fluid or metalworking lubricant are the phosphate ester and water-soluble amine corrosion inhibitor components. The hydraulic fluid and metalworking fluids of the invention also contain a water-soluble polyoxyethylated ester of an aliphatic acid and a monohydric or polyhydric aliphatic alcohol, either one or both said acid and said alcohol being polyoxyethylated, a sulfurized molybdenum or antimony compound and a metal deactivator as well as other adjuvants conventional in this art.

  本发明公开了水基液压油和金属加工润滑剂，它们是用分子量约为 1000 至 75,000 的聚醚多元醇增稠的，该聚醚多元醇是用具有约 12 至 18 个碳原子的α-烯烃环氧化物改性的。令人意想不到的是，上述聚醚多元醇与水基液压油或金属加工润滑剂的成分相结合，会产生协同增稠效果。液压油或金属加工润滑剂中特别有效的成分是磷酸酯和水溶性胺类缓蚀剂成分。本发明的液压油和金属加工液还含有脂肪族酸和一元或多元脂肪族醇（所述酸和所述醇中的一种或两种均为聚氧乙烯）的水溶性聚氧乙烯酯、硫化钼或锑化合物和金属失活剂以及本领域常规的其他佐剂。

  A process for producing a flexible polyurethane foam satisfying low resilience, high vibration absorption and high durability, is presented. A mixture comprising from 95 to 50 mass% of a polyoxyalkylene polyol produced by means of an alkali metal catalyst and from 5 to 50 mass% of a polyoxyalkylene polyol produced by means of a double metal cyanide complex catalyst, is reacted with a polyisocyanate compound in the presence of a catalyst and a blowing agent, to produce a flexible polyurethane foam having a resonance frequency of at most 3.7 Hz, a resonance ratio of at most 3.5 and an impact resilience of at most 70%.

  本发明提出了一种生产满足低回弹性、高吸振性和高耐久性要求的软质聚氨酯泡沫塑料的工艺。在催化剂和发泡剂存在的情况下，一种由 95 至 50 质量％的通过碱金属催化剂生产的聚氧亚烷基多元醇和 5 至 50 质量％的通过双金属氰化物络合催化剂生产的聚氧亚烷基多元醇组成的混合物与一种多异氰酸酯化合物反应，生产出一种共振频率不超过 3.7 赫兹、共振比不超过 3.5 和冲击回弹率不超过 70％的软质聚氨酯泡沫塑料。
