一种水溶性氮化碳润滑剂的制备方法
摘要：
本发明涉及一种水溶性氮化碳润滑剂的制备方法，该方法包括以下步骤：⑴马弗炉中将富氮类前驱物高温煅烧，自然冷却后得到孔状淡黄色固体；⑵常温下，将所述淡黄色固体与去离子水均匀混合，得到固液混合物；⑶所述固液混合物转移至水热釜中，水热反应后，自然冷却、沉降得到上层澄清的弱碱性透明溶液，即为水溶性氮化碳材料；⑷所述水溶性氮化碳材料与咪唑类离子液体混合，即得质量浓度为0.1~200mg/mL的水溶性氮化碳润滑剂。本发明工艺简单、易于规模化生产，所得的润滑剂可显著提高摩擦副的摩擦磨损性能。
摘要（英）：

The invention relates to a method for preparing a water-soluble carbon nitride lubricant. The method comprises the following steps: (1) carrying out high-temperature calcinations on a nitrogen-enriched precursor in a muffle furnace, and naturally cooling so as to obtain a porous light yellow solid; (2) at a normal temperature, uniformly mixing the light yellow solid with deionized water so as to obtain a solid-liquid mixture; (3) transferring the solid-liquid mixture into a hydrothermal kettle, carrying out a hydrothermal reaction, and naturally cooling and precipitating so as to obtain a weakalkali transparent solution of upper supernate, that is, a water-soluble carbon nitride material; (4) mixing the water-soluble carbon nitride material with an imidazolium ionic liquid, thereby obtaining the 0.1-200mg/mL water-soluble carbon nitride lubricant. The water-soluble carbon nitride lubricant is simple in process and easy in on-scale production, and the obtained lubricant is capable of remarkably improving the friction wearing resistance of a friction pair.
