Embodiment 1
[0021] The preparation method of water-soluble polyionic liquid lubricating additive comprises the following steps:
[0022] (1) Weigh 20.771g (0.1mol) of methacryloyloxyethyltrimethylammonium chloride (DMC) and 11.114g (0.1mol) of N-vinylpyrrolidone (VP) and directly mix, at room temperature, Under nitrogen atmosphere, stirring was continued for 0.5 h.
[0023] (2) The system obtained in step (1) was heated to 70° C., and 1.038 g of 2,2-azobisisobutyronitrile (AIBN) was added as an initiator, and the reaction was kept for 12 h under a nitrogen atmosphere. After the reaction was completed, amber was obtained. Crude product of color paste polymer P (DMC / VP).
[0024] (3) dissolving the crude product obtained in step (2) with absolute ethanol, then standing for 1h, performing Soxhlet extraction with a mixture of absolute ethanol and acetone for 12h, and drying to obtain a purified amber paste-like polymer P ( DMC / VP) 22.474 g, ie 0.0705 mol, yield 79.6%. The volume ratio of a...

Abstract
The invention provides a water-soluble polyionic liquid lubricating additive and an application, and relates to the technical field of ionic liquid and industrial lubrication. According to the water-soluble polyion liquid lubricating additive, methacryloyloxyethyl trimethyl ammonium chloride (DMC) and N-vinyl pyrrolidone (VP) are used as monomers, 2, 2-azodiisobutyronitrile (AIBN) is used as an initiator, and P(DMC / VP) is prepared through a polymerization reaction. Then, ion exchange reaction is carried out on P(DMC / VP) and ricinoleic acid to prepare water-soluble polyionic liquid [P(DMC / VP)][RA]. The ionic liquid provided by the invention shows excellent corrosion resistance and antifriction and anti-wear properties after being added into water glycol, and is a water-soluble polyionic liquid lubricating additive with excellent properties.
Description
technical field [0001] The invention relates to the technical field of ionic liquid and industrial lubrication, in particular to a water-soluble polyionic liquid lubricating additive and its application. Background technique [0002] In recent decades, water-based lubricants have received continuous development and continued attention from researchers. Water-based lubricating products are widely used in metal processing such as cutting, rolling, and hydraulic transmission systems. At present, water-based lubricating additives include carboxylic acids and their salts, water-soluble polymers, and active elements containing sulfur and phosphorus. Carboxylates are widely used in industrial production; water-soluble polymers such as SBS-grafted acrylic copolymers and polystyrene emulsions have good tribological properties, but water-soluble polymers with excellent tribological properties Synthesis and application reports of sulfites are still rare; water-soluble additives conta...
