| 摘要 |
The invention relates to a synthetic high-temperature lubricant for lubricating high-temperature belt presses, said lubricant comprising a synthetic base oil mixture [A)] containing a base material [a)] based on naphthalene or a naphthalene derivative, a polyester base material [b)], and a complex ester base material [c)], and an additive packet [B)] containing a corrosion inhibitor [a], an extreme pressure additive [b)], an antioxidant [c)], a nonferrous metal deactivator [d)], and a wear-reducing means [e)]. The aim of the invention is to obtain a synthetic high-temperature lubricant for high-temperature belt presses, which has a corrosive action on copper according to DIN EN ISO 2160 at 150 °C after 24 hours with a degree of corrosion of (1), and passes a steel corrosion test according to DIN ISO 7120. |
