Problems solved by technology

[0010] (7) Good viscosity-temperature performance, high viscosity index, low compressibility
However, the obtained high water-based lubricating fluid products have poor compatibility and stability, are easy to be corrupted and deteriorated, and because the existing oil-soluble lubricating additives such as lead naphthenate are relatively toxic, they also pollute the environment
The other is water-soluble lubricating additives, such as polyethylene glycol and its derivatives, sulfobenzoic acid and dithiodipropionic acid water-soluble carboxylic acid derivatives, etc., using water-soluble lubricants to solve the problem of lubricating fluid stability However, there is still a big gap between its lubricity and oil-based lubricants, and it has not completely solved the problem of poor lubricity of high-water-based lubricants

Embodiment 1-8

[0026] Under mechanical stirring, add the phosphoric acid ester and the alkali into the water in sequence, and after continuing to stir and dissolve, the solution becomes transparent. Under stirring, add nano-silica particles, and stir evenly. The result is a clear to translucent emulsion. In order to compare the composite effect of nanoparticles and water-soluble phosphate, a high-water base liquid containing nano-silica particles or water-soluble phosphate alone was prepared for comparison. The experimental samples of Examples 1-8 and Comparative Examples 1-2 were prepared in this way, and their specific proportions are shown in Table 1.

Abstract

The invention discloses a high-property high-water based lubricant composition, which comprises the following parts: 95-99% water and 1-5% functional additive (lubricant and alkali) and lucricating additive with nanometer silica particle and soluble phosphate, wherein the even grain size of nanometer silica particle is 10-60nm; the high-water based lubricant consists of nanometer silica particle and soluble phosphate, which improves bearing capacity (PB value) and reduces spot-abrasion diameter (D3040); the water based lubricant is fit for metal manufacturing liquid to cut and polish.

Description

technical field [0001] The invention relates to a lubricant in the field of metal processing, in particular to a high water-based lubricant. Background technique [0002] Since the 1990s, with the increasing emphasis on environmental protection and energy conservation worldwide, the widely used mineral-based lubricants are facing severe challenges from environmental requirements due to their poor biodegradability and environmental pollution. Environmentally friendly lubricants have become the development direction of lubricants. It is against this background that High Water-based Fluid (HWBF) lubricants emerged. [0003] High water-based lubricants refer to liquids composed of 1-5% functional additives and 95-99% water. Compared with traditional oil-based lubricants, high water-based lubricants have the following advantages: [0004] (1) Reduce environmental pollution and benefit workers' health. Higher water-based lubricants are cleaner since they do not contain oil; ...
