Technical Field
The invention relates to the technical field of aqueous lubricants, in particular to an environment-friendly aqueous cold extrusion lubricant, and a preparation method and application thereof.

In the cold extrusion processing technology of metal, the use of a lubricant is critical, the contact surface can generate resistance for preventing tangential movement, namely external friction force when the processed metal moves relative to a die in the cold molding process of the metal, the external friction force can increase the force and energy required by processing, so that the metal surface is subjected to lubrication treatment, the lubricant is a lubrication medium for reducing the friction resistance of a friction pair and slowing down the abrasion of the friction pair, a firm and tough lubrication film is formed between a workpiece and the die, the purpose of reducing the friction is achieved, if the lubrication of the surface of the lubrication film cannot meet the requirement, the phenomena of die abrasion, adhesion, scratch and the like on the surface of the workpiece can be aggravated, and the development of lubrication technology can promote the development of cold molding processing of the metal.
In the cold molding process of metal, the application of the phosphating-saponification lubrication technology is quite common, but the phosphating-saponification needs to be subjected to seven working procedures of alkali washing oil removal, water washing, acid washing rust removal, water washing, phosphating, water washing, saponification and the like, and the problems of high consumption of raw materials and energy sources, poor total working environment, easiness in causing environmental pollution and the like exist. In recent years, the use of phosphating-saponification lubrication technology has gradually stopped. Therefore, finding an environment-friendly lubricant suitable for metal cold forming is a hot spot of research.
At present, most of novel water-based lubricants on the market are high-molecular graphite type lubricants, and the lubricants have a certain lubricating effect on metal cold molding, but the graphite type lubricants also have a plurality of hidden dangers, such as poor lubricating performance, electric conduction, difficult cleaning, heavy pollution and the like, and have higher cost, and the black dust pollution in the production environment is serious, so that the method is unfavorable for the physical health of workers.

the water-based interface lubricant has the characteristics of cooling, cleaning and pollution prevention, and can reduce the friction resistance of friction pairs and slow down wear.
Further, the aqueous stearate is aqueous zinc stearate, aqueous calcium stearate, aqueous barium stearate or aqueous lithium stearate.
Further, the friction coefficient of the nano tungsten disulfide is 0.1-0.3, and the particle size is 0.5-0.9 mu m.
Further, the nonionic surfactant comprises one or more of alkyl alcohol amide, alkylphenol polyoxyethylene, higher fatty alcohol polyoxyethylene and C13 isopropanol amide;
the aqueous interface lubricant is prepared from alcohol ether carboxylic acid, polyoxyl castor oil, olefin and chlorinated fatty acid; the weight percentages of the components are 12.5 percent of alcohol ether carboxylic acid, 27.5 percent of polyoxyl castor oil, 10 percent of olefin and 50 percent of chlorinated fatty acid.

the defoamer comprises one or more of polyoxyethylene polyoxypropylene pentaerythritol ether, polyoxyethylene polyoxypropylene alcohol amine ether, polyoxyethylene lauryl ether, alkenyl succinic acid and alkenyl succinic acid half ester.
The preparation method of the environment-friendly water-based cold extrusion lubricant comprises the following steps:
s1: adding water and a nonionic surfactant into a reaction kettle until the nonionic surfactant is completely dissolved;
s2: adding water-based stearate and nano tungsten disulfide into the solution prepared in the step S1, heating, continuously stirring, and continuously heating at 60 ℃ for 1h;
s3: and (3) after the solution is cooled, adding an aqueous interface lubricant, polyethylene glycol, polytetrafluoroethylene, a dispersing agent and a defoaming agent into the solution obtained in the step (S2) to obtain the lubricating liquid.
The environment-friendly water-based cold extrusion lubricant prepared by the method is applied to mechanical lubrication.
The beneficial effects of the technical scheme are that:
1) The invention solves the problems of poor lubricating performance, electric conduction, difficult cleaning and the like of the conventional lubricant and the conventional graphite lubricant in the environment-friendly field, improves the problem of high friction coefficient of the graphite-free lubricant, and provides an environment-friendly water-based cold extrusion lubricant which is uniform in dispersion, good in lubricating effect, pollution-free, safe and environment-friendly in preparation process for the water-based lubricant.

The lubricant is suitable for lubrication under various severe conditions such as high temperature, high pressure, high vacuum, high load, high rotation speed, high radiation, strong corrosion, ultralow temperature and the like, and can increase the application scene of the lubricant.
The two are combined, the synergistic effect can be achieved, the lubrication effect of the lubricant is improved, and the lubricant belongs to clean raw materials and is not easy to cause pollution.

Effect verification
1. Determination of the coefficient of Friction
The coefficient of friction of the environment-friendly aqueous cold extrusion lubricants prepared in examples 1 to 3 and comparative examples 1 to 3 was measured by using a four-ball friction tester, and the average coefficient of friction was measured at 30℃under a relative humidity of 30%, a load of 500N, a rotation speed of 1200r/min and a wear of 60min, and the results are shown in Table 1.
| Example 1 | Example 2 | Example 3 | Comparative example 1 | Comparative example 2 | Comparative example 3 | |
| Coefficient of friction | 0.079 | 0.073 | 0.082 | 0.095 | 0.103 | 0.112 |
As can be seen from Table 1, the friction coefficient of the lubricant prepared by the invention can be as low as 0.073, thus achieving the ideal lubrication effect; after polyethylene glycol and polytetrafluoroethylene components are removed, the friction coefficient is increased; after removing the nano tungsten disulfide component, the friction coefficient is increased; after removing the nano tungsten disulfide and polytetrafluoroethylene components, the friction coefficient is increased to 0.112, so that the lubricating effect of the aqueous lubricant is improved through the synergistic effect of the nano sulfur dioxide and polytetrafluoroethylene.
The lubricants of examples 1 to 3 and comparative examples 1 to 3 were subjected to physical and chemical property tests, and the results are shown in Table 2.

As shown in Table 2, the lubricant prepared by the invention has high kinematic viscosity, high viscosity index, up to 962N maximum seizure-free load and good cutting stability, and has good lubrication effect, stable performance and high bearing capacity. After the nano tungsten disulfide and polytetrafluoroethylene are removed in the comparative example 3, the maximum non-biting load is only 876N, the stability is as high as 0.3%, and the lubrication effect, the stability and the bearing capacity of the product are all reduced.
The foregoing is merely exemplary embodiments of the present invention, and specific structures and features that are well known in the art are not described in detail herein. It should be noted that modifications and improvements can be made by those skilled in the art without departing from the structure of the present invention, and these should also be considered as the scope of the present invention, which does not affect the effect of the implementation of the present invention and the utility of the patent.
