摘要:
An environment-friendly basic oil based on natural materials for the formulation of hydraulic oils having improved viscosity at elevated temperature and lower pour point contains rapeseed oil or soybean oil as the main component, an antioxidant selected from methoxyphenol, ethoxyphenol, butyl hydroxyanisole, butyl hydroxytoluene, methoxyhydroquinone, ethoxyhydroquinone, tertiary butyl hydroquinone, and tocopherol, and an ester of a monocarboxylic acid or a fatty acid.
