Environment-friendly waterborne guide rail lubricating medium with good compatibility with cutting fluid

Abstract

The invention discloses an environment-friendly waterborne guide rail lubricating medium with good compatibility with cutting fluid. The waterborne guide rail lubricating medium comprises a waterborne anti-rust agent, organic amine, a synthetic ester extreme pressure agent, a lubricating agent, a complexing agent, a defoaming agent and water. The creeping phenomenon is reduced or eliminated; a guide rail system is kept clean through the cleaning performance of synthetic ester; the lubricating medium with water as a continuous phase does not contain mineral oil, pollution of the hardly degradable substance, namely the mineral oil to the environment is avoided, and the effluent treatment burden is reduced. The lubricating medium is mutually soluble with the totally synthesized, micro-emulsified and emulsified cutting fluid, the guide rail lubricating medium cannot float on the surface of the cutting fluid, and decay caused by the lubricating medium is avoided; no elements of sulfur, chlorine and phosphorus are contained, and the negative effect caused by the elements is avoided. The product leaks into the cutting fluid, and the lubricating and anti-corrosion performance of the product can be enhanced; even when the cutting fluid is splashed to the surface of a guide rail, the cutting fluid can be evenly dispersed; the product contains the waterborne anti-rust agent, and enough anti-rust performance is provided.

Description

technical field [0001] The invention belongs to a lubricant used in a guide rail lubrication system, in particular to an environmentally friendly water-based guide rail lubricating medium with good compatibility with cutting fluid and more additional functions. Background technique [0002] The current mechanical rail lubrication system is developing rapidly. The traditional hydrostatic support system sends the lubricating medium of the guide rail to the support surface through pressure. There is no contact between metal and metal. The internal friction of the fluid is the only friction that occurs. When the machine tool moves on the guide rail with heavy load and low moving speed, and the static friction When the coefficient is relatively large, the machine tool does not advance steadily but jumps forward, resulting in crawling. In order to solve the above-mentioned problems, the existing guideway system has arranged bearing-type components such as balls or rollers with li...

Problems solved by technology

The lubricating medium of oily guideway is more commonly used, and most of them are mineral oil-based guideway oil. Mineral oil accounts for more than 90% of the product, and its biodegradability in the natural environment is poor. Any form of discharge or treatment will increase the additional burden.

At the same time, although the oily guide rail lubricating medium containing mineral oil can maintain the good operation of the guide rail system itself, it leaks into the cutting fluid tank. Because it has no miscibility with the cutting fluid, after the machine tool cutting the workpiece is shut down, the guide rail lubricating medium floats on the The surface of the cutting fluid tank causes the corruption of the cutting fluid, the continuous production of anaerobic bacteria, the decrease of the service life of the cutting fluid, and the increase of production costs; at the same time, the cutting fluid splashes on the guide rail. Causes corrosion and other defects of the guide rail, affecting sliding accuracy

[0004] In addition, most of the current oil-based or water-based guide way lubricants still contain sulfur, chlorine and phosphorus in the various additives used.

For the processing of some more active metals, such as aluminum, the introduction of chlorine will cause potential corrosion of aluminum parts. For the processing of copper alloys, sulfur corrosion often occurs, and the addition of phosphorus will also accelerate the growth of bacteria in summer. the possibility of corruption and malpractice
