聚醚型合成压缩机油的研制

使用聚醚基础油，通过对抗氧剂、极压抗磨剂、助溶剂和防锈剂等添加剂的筛选及性能考察，研制了一种聚醚型合成压缩机油。该产品黏度指数达到210以上，旋转氧弹时间超过1 000 min ，铜片腐蚀（100 ℃，3h）为1b级，四球试验的钢球磨斑直径为0.5 mm左右，具有优异的黏温性能、氧化安定性、防锈抗腐性和良好的极压抗磨性，达到国外同类油品质量水平。经过一年的实际使用，油品磨损金属质量分数低于30 μg/g，表明研制产品能够满足烃类气体压缩机的润滑要求。

RESEARCH ON SYNTHETIC COMPRESSOR OILS BASED ON POLYETHER

Using polyether base oil, a kind of polyether type synthetic compressor oil was developed by screening and investigating the properties of additives such as antioxidation agent, extreme pressure antiwear agent, co-solvent and anti-rust agent. The viscosity index of the product was more than 210, the rotary oxygen bomb time was more than 1000 minutes, the copper strip corrosion（100 ℃，3 h） was grade 1b, and the scar diameter after the four ball milling test was about 0.5mm. The developed product has an excellent performance in viscosity-temperature，oxidation stability，rust resistance and anti-corrosion and good extreme pressure anti-wear. The quality of the product reached the level of foreign similar oils. After practical use for one year，the wear metal content was less than 30 μg/g, showing that the developed product can meet the lubrication requirements of hydrocarbon gas compressors.
