    • The present invention provides an insulating material for the enameled wire of a motor of a refrigeration compressor using hydrofluorocarbons as the refrigerant and, as the refrigerating machine oil, a synthetic lubricating oil having at least one ester bond in a molecule such as ester-modified polyoxyalkylene glycol type, ester-modified ether type or ester type, which insulating material contains a compound having at least one carbodiimide group.This insulating material for the enameled wire of a motor of a refrigeration compressor, which is free from the above-mentioned problems of the prior art, which can prevent the surface deterioration or peeling (blister or cracking) etc. seen in the conventional insulating material used for covering the enameled wire (e.g. magnet wire) of a refrigeration compressor, caused by a mixture of the hydrofluorocarbons and the synthetic lubricating oil both used in the compressor, which invites neither insulation breakdown nor reduction in insulation and has improved resistances to said substitute flon and said synthetic lubricating oil, and which further can impart deterioration resistance to the synthetic lubricating oil.
    • 本发明提供一种使用氢氟烃作为制冷剂的制冷压缩机的电动机的漆包线绝缘材料,作为制冷机油,在分子中具有至少一个酯键的合成润滑油如酯改性的聚氧化烯 乙二醇型,酯改性醚型或酯型,该绝缘材料含有具有至少一个碳二亚胺基团的化合物。 用于制冷压缩机的电动机的漆包线的绝缘材料,其不含现有技术的上述问题,其可以防止在常规绝缘材料中看到的表面变质或剥离(起泡或开裂)等 用于覆盖由压缩机中使用的氢氟烃和合成润滑油的混合物引起的制冷压缩机的漆包线(例如电磁线),其既不会绝缘击穿也不会减少绝缘,并且具有改善的对所述替代物的抵抗力 氟利昂和所述合成润滑油,并且还可以赋予合成润滑油耐劣化性。
