Anti-corrosion and anti-rust agent for neutral emulsified cutting fluid

The invention discloses an anti-corrosion and anti-rust agent for neutral emulsified cutting fluid, which is obtained by mixing Guerbet acid and dicyclohexylamine according to the mass ratio of (1-1.5): 1 and reacting at high temperature, wherein the reaction temperature ranges from 60 DEG C to 80 DEG C, and the reaction time ranges from 30 min to 40 min. The anti-corrosion and anti-rust agent disclosed by the invention is added into the neutral emulsified cutting fluid, so that the anti-rust and anti-corrosion performance of the emulsified cutting fluid under the condition that the pH value is neutral is effectively realized, and the industrial application of the neutral emulsified cutting fluid is ensured. 本发明公开了一种用于中性乳化切削液的防腐防锈剂，所述防腐防锈剂由格尔伯特酸与二环己胺按质量比1～1.5：1混合，并在高温下反应得到；其中，反应温度为60～80℃，反应时间为30～40min。本发明的防腐防锈剂添加到中性乳化切削液中，有效解决了乳化切削液pH值中性条件下的防锈与抗腐败性能，使中性乳化切削液的工业应用得到保证。
