A multifunctional, high-performance hydrocarbon composition is demanded. Concretely, a metalworking oil composition having high workability even under a severer lubricating condition while resisting to high productivity, and further capable of suppressing deterioration of working environments or degradation of quality of a product without rise of lubricant cost, a metalworking oil composition for minimal quantitative lubrication system, which is excellent in characteristics as a water-insoluble lubricant for nonferrous metalworking and also in characteristics as a lubricant for cutting/grinding by minimal quantitative lubrication method, and can attain improvement in working efficiency and a further extended tool life, an electric discharge machining oil improved in working environments such as odor or skin roughness and further improved in processing rate, particularly processing rate in high-level finish, a rust preventing oil composition improved in resin compatibility, and a detergent excellent in adaptability with organic material are demanded.
Therefore, metalworking oil which contains, as hydrocarbon base oil, hydrocarbon base oil having a density at 15°C of 0.7 to 0.8 g/cm3, and including a n-paraffin content of 10 to 90% by mass, an aromatic content of 0 to 3 % by volume, and a naphthene content of 0 to 20% by volume, a metalworking oil including the above-mentioned base oil and ester oil, and electric discharge machining oil, rust preventing oil, and a detergent composition including the above-mentioned base oil are provided.
我们需要一种多功能、高性能的碳氢化合物组合物。具体地说,一种金属加工油组合物,即使在较苛刻的润滑条件下也具有较高的加工性,同时还能抵御高生产率,并能在不增加润滑油成本的情况下进一步抑制工作环境恶化或产品质量下降;一种用于最小定量润滑系统的金属加工油组合物,该组合物作为用于有色金属加工的水不溶性润滑油,以及作为通过最小定量润滑方法进行切割/磨削的润滑油,具有优异的特性、此外,还需要一种改善工作环境(如气味或皮肤粗糙度)并进一步提高加工率(尤其是高光洁度加工率)的放电加工油、一种提高树脂兼容性的防锈油成分以及一种与有机材料适应性极佳的清洁剂。
因此,提供了作为碳氢化合物基础油的金属加工油、15°C 时密度为 0.7 至 0.8 g/cm3 的碳氢化合物基础油、正石蜡含量为 10 至 90%(质量)、芳烃含量为 0 至 3%(体积)、环烷含量为 0 至 20%(体积)的金属加工油、包括上述基础油和酯类油的金属加工油、电火花加工油、防锈油和包括上述基础油的洗涤剂组合物。
