Problems solved by technology

Now most lubricants are oil-soluble. In many working conditions, such as cannon barrel cold extrusion and self-tightening processing, metal cutting, metal wire drawing, metal punching and extrusion, etc., the grease is used only once, which is wasteful. Serious and not environmentally friendly; and after the operation is completed, special cleaning agents are required for cleaning, which is very costly

Embodiment 1

[0017] Put 45g of water-soluble polyether, 41.4g of distilled water, and 11g of stearic acid into a blending kettle, heat at about 70-80°C and stir evenly to obtain a mixed solution after complete dissolution. Then put 1g of calcium hydroxide and 0.55g of sodium hydroxide into the mixture, and keep the temperature at 87-95°C for saponification for 30min. After saponification, add 1 g of antiwear agent melamine cyanurate and zinc dialkyldithiophosphate composite solution, and 0.05 g of rust inhibitor benzotriazole, cool naturally to room temperature, grind twice, and filter to obtain the finished product.

Embodiment 2

[0019] Put 30g of water-soluble polyether, 45g of distilled water, and 20g of stearic acid into a blending kettle, heat at about 70-80°C and stir evenly, and obtain a mixed solution after complete dissolution. Then put 2g of calcium hydroxide and 1g of sodium hydroxide into the mixture, and keep the temperature at 87-95°C for saponification for 30min. After saponification, add 1.5 g of anti-wear agent melamine cyanurate and zinc dialkyldithiophosphate composite solution, and 0.05 g of anti-rust agent benzotriazole, cool naturally to room temperature, grind twice, and filter to obtain the finished product.

[0020] The finished products obtained in the above examples are tested, and the results show that the appearance of the water-based lubricating grease is milky white, the dropping point reaches more than 100, the penetration can reach the No. 1 hardness standard, and the anti-wear performance can meet the requirements of the basic working conditions of metal processing.

Abstract

The invention relates to the field of lubricating grease, and particularly relates to environment-friendly water-based lubricating grease and a preparation method thereof. The water-based lubricating grease comprises the following components in percentage by mass: 65-90% of basic liquid, a mixed base thickening agent, 0.5-3% of extreme-pressure anti-wear additive and 0.02-2% of antirust agent, wherein the basic liquid is a mixture of water-soluble polyether and distilled water, and the mixed base thickening agent is generated by reaction of 1-4% of calcium hydroxide and 0.5-1.5% of sodium hydroxide with 6.5-24.5% of stearic acid. The water-based lubricating grease prepared by the method has the advantages of full lubrication and adhesion, good heat transfer and cooling effect and easy cleaning operation and is particularly suitable for occasions such as metal stamping and extrusion machining, metal rolling, metal wire drawing and metal pipeline machining.

Description

technical field [0001] The invention relates to the field of lubricating grease, in particular to an environment-friendly water-based lubricating grease and a preparation method thereof. Background technique [0002] With the continuous consumption of non-renewable resources such as petroleum, the global energy crisis has already appeared, and lubricants closely related to petroleum have become very common in various industries such as industrial equipment and daily necessities. Now most of the lubricants are oil-soluble. In many working conditions, such as cannon barrel cold extrusion self-tightening processing, metal cutting, metal wire drawing, metal punching and extrusion, etc., the grease is one-time use, waste Serious, it is not environmentally friendly; and after the operation is completed, special cleaning agents are required for cleaning, and the cost is very high. Contents of the invention [0003] The invention provides a water-based lubricating grease which ca...
