Resumen de: WO2026155643A1

The present invention relates to a semi-synthetic nano-soluble compound designed to improve the bioresistance and effectiveness of lubricants in metal processing. This compound incorporates nanoadditives that optimise properties such as thermal conductivity and wear resistance, resulting in more effective lubrication and extending the useful life of the tools. The compound is formulated with several key components, including a base oil, viscosity modifiers, dispersing agents, anti-wear agents, heat stabilisers, emulsifiers and biocides in specific proportions. Unlike conventional formulations, this invention is characterised in that it avoids the use of harmful additives such as chlorates, sulphates and phosphates. The synergy between the nanoadditives and the other ingredients significantly reduces friction, thereby optimising working conditions in biologically contaminated environments. In addition, the resulting emulsion is stable, thus maintaining its effectiveness over time and improving the performance of cutting tools in industrial processes.
